Blue Origin New Glenn NG-2 launches on November 13. 2025

2025 was an incredibly busy year in spaceflight, both here at the Cape and also globally. By Christmas, providers broke previous orbital launch records, with over 300 successful flights globally, largely driven by SpaceX’s Falcon 9 for Starlink satellite deployments.

SpaceX: Launch Cadence at an Unmatched Scale

SpaceX further extended its dominance in 2025 with over 130 orbital launches across the year, the vast majority using its Falcon 9 rocket. The company continued flying at a pace unmatched by any other launch provider, supporting satellite deployments, ISS crew and cargo missions, and national security payloads in addition to continuing building out its wildly popular Starlink offering.

Starlink

On October 25, 2025, SpaceX launched its 10,000th Starlink satellite. Space.com quoted noted satellite tracker Dr. Jonathan McDowell of the Harvard–Smithsonian Center for Astrophysics, saying that there are currently 9,357 Starlink satellites in orbit, with 9,347 in operational positions. The constellation serves over 9 million customers across 100 countries and territories. It is estimated that the company adds around 20,000 new customers daily.

Reusable boosters remain central to that success. Several Falcon 9 first stages flew 20 or more times, reinforcing the idea that rapid reuse is no longer experimental but routine. One of its boosters, B1067, has now flown 32 times and is currently at SpaceX’s facilities at the Kennedy Space Center, being refurbished for another flight. The company has publicly stated that it seeks to certify Falcon 9 boosters for up to 40 flights, and in 2025, several of the company’s boosters have fewer than ten missions remaining to meet that goal.

Starship test flights also continued launching from Texas, focusing on vehicle upgrades, heat-shield performance, and recovery techniques aimed at future missions beyond Earth orbit. The company is also continuing to build out its Boca Chica infrastructure, with a new launch pad nearing completion at the end of this year. Flights from the new facility should take place in the first part of 2026.

SpaceX also received approval to begin converting Space Launch Complex 37 (SLC-37) at Cape Canaveral for Starship operations. The site, previously used by United Launch Alliance’s Delta IV, gives SpaceX a second major East Coast launch location and points to long-term plans for higher-energy missions beyond Falcon 9.

Meanwhile, NASA, the FAA and other relevant authorities are finishing an Environmental Impact Statement for another Florida-based Starship launch pad at LC-39A at Kennedy Space Center. The tower there has long been under construction, with work continuing apace at that facility in addition to the new pad a few miles south at SLC-37.

SpaceX has stated that its goal is to launch from the Cape in 2026.

SpaceX has also begun construction of a new “Gigabay” facility for Starship at its Roberts Road site at Kennedy Space Center. That facility is large — not quite the size of the venerable VAB, but large nonetheless — and should be completed in 2026.

Blue Origin: New Glenn Finally Flies

After years of development, Blue Origin reached orbit for the first time with the debut launch of its New Glenn rocket in 2025. Flying from LC-36 at Cape Canaveral Space Force Station, the successful flight validated the vehicle’s core systems and marked the company’s entry into the heavy-lift orbital launch market.

NG-1, Blue’s mission designation for the debut flight, also had a tertiary goal of landing the New Glenn first stage, but that effort was unsuccessful. The payload reached its target orbit, however, making the flight a rousing success for a company long discounted by many in the space community.

Momentum continued on New Glenn’s second launch, when Blue Origin successfully landed its reusable first-stage booster on its recovery ship ‘Jacklyn’. The recovery showed that the company’s emphasis on reusability was now operational and not theoretical, and it positioned New Glenn as a serious competitor in the heavy-lift category.

Notably, Blue’s second New Glenn flight was much smoother than the debut. This was an expected improvement, but it clearly showed that Blue had taken the lessons learned from NG-1 to heart, made operational improvements, and applied them to the NG-2 flight.

2025 also saw Blue Origin significantly advancing its Blue Origin Blue Moon lunar lander program, as it continued preparing its Blue Moon Mark 1 (MK1) lunar lander for its first demo mission to deliver payloads to the lunar South Pole, presumably on the New Glenn NG-3 flight in early 2026.

Plans to reuse ‘Never Tell Me the Odds’, the booster used for the NG-2 flight, on NG-3. If successful, Blue Origin will achieve landing and then reusing a booster in relatively quick succession.

Blue is continuing development of its second lunar lander, Blue Moon Mark 2 (MK2). While they have made few public statements on the status and progress of the project, it is believed that they are building a flight-capable cabin for testing and crew training for the larger MK2, one of two of NASA’s selected crewed landers. Additionally, Blue is said to be working on life support, thermal control, and docking systems for MK2. Undoubtedly, the results from the MK1 mission will greatly inform the future designs of MK2.

Finally, Blue Origin created a new internal group focusing on national security missions for the US Government, and to run it they hired ULA’s CEO, Tory Bruno.

United Launch Alliance: A Year Full Of Change

2026 was a transitional year for United Launch Alliance, and one that has many observers wondering about the company’s long-term prospects, especially now that their former leader, Tory Bruno, has left to work for the competition.

One one hand, the company has an estimated 70 launches backlogged, with the majority being LEO satellites for Amazon’s Leo telecommunications constellation. On the other, Vulcan has been slow to build any cadence, with August 2025 being the last launch and NET March 2026 for its next flight. That’s not going to trim the backlog appreciably.

The reasons go back to last year: October of 2024, Vulcan’s second flight, CERT-2 saw one of its solid rocket boosters (SRB) nozzles detach due to a manufacturing defect in the nozzle’s internal insulator, causing an off-nominal burn. However, the main engines compensated, kept the rocket on course, and the mission still achieved its orbital goals. The company and Northrop Grumman conducted an investigation to identify the issue and prevent any recurrence.

That took several months and most of ULA’s inertia but the company continued to soldier on with other missions while it waited for the results and corrections to Vulcan.

In written testimony to Congress in May 2025, Major General Stephen G. Purdy stated the Vulcan program had performed unsatisfactorily over the past year. He noted that “major issues with the Vulcan have overshadowed its successful certification,” directly resulting in the grounding of four national security missions.

Due to Vulcan’s delays, the original 60/40 mission split favoring ULA under the NSSL Phase 2 contract shifted closer to 54/46 (or nearly 50/50) in 2025, as more missions were awarded or reassigned to SpaceX. Now, Blue Origin is also in the competition future NSSL launches, with Blue expected to complete NSSL Certification next year. SpaceX isn’t going anywhere either, leaving ULA walking a tightwire in the coming year.

On August 13, 2025, ULA successfully launched its first national security mission for the U.S. Space Force using a Vulcan VC4S. The mission deployed NTS-3, an experimental navigation satellite designed to enhance GPS resilience and was a complete success.

With its Delta family retired, ULA successfully conducted four major launches for Amazon’s broadband constellation (Project Kuiper, now Amazon Leo) using Atlas V rockets. All of those missions were textbook perfect, as has been customary for the rocket.

ULA is planning to increase its launch cadence in 2026, and has all but completed a second launch tower and vertical integration facility for Vulcan.

Finally, close to the Christmas holiday, ULA announced that CEO Tory Bruno had resigned “to pursue another opportunity.” For Bruno, that opportunity turned out to be leading Blue Origin’s new National Security Group, where he will ostensibly be competing with his old company for lucrative USSL launches. At Blue Origin, Bruno will have a reusable rocket system in hand, while ULA will compete with its Vulcan rocket and the vast depth of experience the company has on its resume.

ULA COO John Elbon was named as the Interim CEO in a press release issued today. John Elbon is the chief operating officer for United Launch Alliance (ULA). Before his new role, Elbon was responsible for the operations of the Atlas, Delta, and Vulcan Centaur launch vehicle programs, including design, engineering, integration, production, quality assurance, and program management.

Previously, Elbon served as vice president and program manager for Boeing’s Commercial Programs. In that position, Elbon managed Boeing’s efforts on NASA’s Commercial Crew Space Act Agreements, including the first two phases of the Commercial Crew Development, which for Boeing was the Starliner CST program.

Rocket Lab

In 2025, Rocket Lab completed 21 Electron launches, maintaining one of the highest success rates in the small-satellite market and continuing to serve commercial, civil, and national security customers. Electron missions flew from both New Zealand and Virginia, reinforcing Rocket Lab’s value as a responsive, geographically flexible company.

At the same time, much of Rocket Lab’s strategic focus shifted toward the future with continued development of Neutron, its upcoming medium-lift, partially reusable rocket. Throughout 2025, the company advanced engine testing, structural manufacturing, and launch infrastructure work at Wallops Island, Virginia.

While Neutron did not fly during the year as the company had expected, visible progress signaled Rocket Lab’s intent to move beyond small payloads and compete for larger commercial constellations and U.S. government missions later in the decade.

Beyond launch vehicles, Rocket Lab also expanded its space systems business, delivering spacecraft components, solar panels, and complete satellites to a growing customer base.

Rocket Lab’s share price rose sharply in 2025, with investors seeing significant gains in their positions.

Taken together, 2025 was not a year of dramatic firsts for Rocket Lab, but one of consolidation and preparation — proving it could sustain a high launch tempo today while methodically building the capability to play a much bigger role in the launch market of the future.

NASA

The year was marked by layoffs, with uncertainty and dread a prevalent mood for many at the agency as the new presidential budget called for drastic cuts in NASA’s science programs.

The year also saw a great deal of preparation for a return to the Moon under Artemis, a major anniversary for the International Space Station, and visible progress in science, aviation, and artificial intelligence. It was also a year of leadership change, with private-space veteran Jared Isaacman nominated and later confirmed to a senior NASA leadership role, signaling closer alignment between the agency and the commercial space sector.

The year set the tone for a decade defined by sustained activity rather than isolated milestones.

Lunar exploration remained a central focus. NASA continued methodical preparations for Artemis II, the first crewed mission to orbit the Moon since Apollo, completing the stacking of the Space Launch System rocket and Orion spacecraft and running dozens of mission simulations to stress-test procedures and crew timelines. At the same time, the Commercial Lunar Payload Services program delivered tangible results.

Firefly Aerospace’s Blue Ghost Mission One achieved a successful lunar landing in early March, while Intuitive Machines’ second Nova-C lander reached the surface days later, gathering data despite landing on its side. Together, the missions reinforced NASA’s strategy of using commercial partners to deliver science and technology to the Moon more frequently and at lower cost.

Beyond the Moon, NASA continued expanding its deep-space science portfolio. In November, the twin ESCAPADE spacecraft were launched toward Mars to investigate how the planet’s weak magnetic environment interacts with the solar wind, a key factor in understanding how Mars lost much of its atmosphere. Planning for future lunar surface science also advanced when Blue Origin was selected to deliver the VIPER rover to the Moon’s south pole later in the decade, keeping the agency’s search for water ice on track.

Space science and Earth observation saw several high-profile missions reach orbit in 2025. In March, NASA launched the SPHEREx space telescope to conduct an all-sky infrared survey while also deploying the PUNCH mission to study the Sun’s outer atmosphere and the origins of the solar wind.

Over the summer, the NISAR satellite, a joint mission with India’s ISRO, lifted off to provide unprecedented radar mapping of Earth’s ice sheets, forests, and changing landscapes. Astronomers also turned their attention outward as NASA coordinated global observations of 3I/ATLAS, only the third confirmed interstellar object ever detected passing through our solar system.

Closer to home, the Lucy spacecraft added another successful asteroid flyby to its mission, passing 52246 Donaldjohanson and returning detailed images that will help refine models of early solar system formation.

Human spaceflight milestones were just as prominent aboard the International Space Station. In November, the ISS marked 25 consecutive years of continuous human presence in orbit, a milestone that underscored its role as a testbed for long-duration missions beyond Earth.

Earlier in the year, astronaut Suni Williams set a new record for cumulative spacewalk time by a woman, reflecting both the station’s ongoing maintenance demands and the growing experience of its crews. Williams had the opportunity to mark that achievement because she and Butch Wilmore were part of the ill-fated Boeing CFT mission that launched in 2024 and led to an unexpected nine-month stay on station. The Boeing CFT astronauts joined Crew 9, which launched in September 2024 and landed in the Pacific Ocean on March 18, 2025.

Logistics capabilities also expanded with the arrival of Northrop Grumman’s first Cygnus XL cargo spacecraft, which delivered larger payloads and increased flexibility for station resupply. SpaceX provided the lift for Cygnus, as Northrop Grumman has yet to complete development of a new Antares 300-series replacement.

NASA also made visible progress in aviation and emerging technologies. The X-59 quiet supersonic aircraft completed its long-awaited first flight in October, validating a design meant to dramatically reduce sonic booms and potentially reopen the door to commercial supersonic travel over land.

In materials science, the agency’s heat-resistant superalloy GRX-810 earned recognition as NASA’s 2025 Commercial Invention of the Year, highlighting work aimed at improving engines and structures for extreme environments.

Taken together, 2025 was less about a single headline mission and more about steady progress across many fronts. NASA strengthened its lunar pipeline, celebrated a quarter-century of continuous human spaceflight, launched major new science missions, and laid the groundwork for how future exploration will be managed and analyzed. They also got a new administrator after a tumultuous nomination process. Jared Isaacman will bring many new ideas and changes to the agency, changes that will hopefully rejuvenate and reinvigorate the US space program.

Others

Sierra Space

In 2025, Sierra Space moved its Dream Chaser program through a series of important ground milestones while also reworking its near-term flight plans. The spaceplane, named Tenacity, completed extensive pre-flight testing, including electromagnetic compatibility checks and runway tow trials, clearing several technical hurdles ahead of flight. That flight, planned for 2024, will now take place in 2026. Maybe.

The program’s first mission was significantly reshaped. What was initially planned as a cargo run to the International Space Station was revised into a standalone orbital demonstration, now targeted for late 2026. NASA amended its contract with Sierra Space, removing guaranteed ISS delivery missions as the company redirected more attention toward defense and national security work.

As a result, Tenacity’s debut will focus on proving core flight and reentry capabilities rather than docking operations. The change reflects both development challenges and the additional certification steps required for ISS missions. While near-term station flights are no longer assured, Dream Chaser could still play a role in future logistics, including potential cargo deliveries to commercial space stations such as Orbital Reef, once the vehicle completes its initial orbital testing.

Relativity

Eric Schmidt

In 2025, Relativity Space entered a new phase after a major leadership shakeup. In March, Eric Schmidt stepped in as chief executive following a substantial investment in the company. Under his leadership, Relativity moved away from its earlier goal of fully 3D-printed rockets, adopting a more pragmatic hybrid manufacturing strategy while accelerating development of its larger, reusable Terran R launch vehicle.

Schmidt is a former Google

Stoke Space

Stoke Space, the Kent, Washington, company founded by former Blue Origin and SpaceX employees, had a good 2025, making major progress toward the first launch of its Nova rocket.

Rockets need launch pads, and Stoke has rebuilt SLC-14 at Cape Canaveral Space Force Station to modern standards for Nova. This is no small accomplishment, and on top of that, Stoke was respectful of the history of 14: this is where John Glenn launched in Mercury-Atlas 6, becoming the first American to orbit the Earth.

As for Nova itself, work is focused on final hardware qualification as the company simultaneously activates SLC-14. Stoke had previously planned for a 2025 debut of Nova, but mid-year, the company shifted to the right on the launch calendar in order to complete SLC-14 and to iron out any remaining issues with Nova.

The 40.2-meter (132-foot) tall rocket is expected to fly in the early part of next year. Stoke is also planning to slowly introduce reusability, so expect the first launch to be expendable.

Boeing

In 2025 Boeing welcomed a new CEO, Kelly Ortberg, previously the president and CEO of Rockwell Collins. Ortberg promised major changes throughout the company, including its spaceflight division.

In November 2025, NASA reduced Boeing’s Commercial Crew contract from six planned missions to the International Space Station (ISS) down to four. This followed technical issues during the 2024 crewed flight test that necessitated the astronauts’ return on a SpaceX vehicle in early 2025. The next mission for Starliner will be uncrewed and carrying cargo, but no date for that mission has been announced.

The news was not all bad for Boeing: their autonomous X-37B spaceplane continued its eighth mission, conducting long-duration orbital experiments as well as novel orbital maneuvers that can quickly place the spacecraft in a new orbit very quickly. In the quickly militarizing orbital environment, this is a tactical advantage yet to be demonstrated by any other nation.

Boeing also continued working on the SLS core stage. It’s Artemis II hardware is in the VAB awaiting rollout and at the time of this writing, the core stage for Artemis III is in an advanced state of manufacturing. After that, it is difficult to tell if the SLS rocket will be canceled by NASA and the Trump administration or if Boeing and others will continue manufacturing the rocket.

Taken overall, the year was an incredibly exciting one, but also one that sets the stage for the future: in 2026 humans will return to cislunar space and further development for landing on the lunar surface will continue apace. Vast Space is planning to launch Vast-1, the first privately owned and operated space station in LEO. We’ll also see SpaceX passing 10,000 Starlink satellites on orbit at some point in 2026, along with Amazon’s nascent Leo constellation starting to take form. There will be new rockets making their debut, and in between, lot of launches, especially Falcon 9 launches.

Stay tuned.

NASA and Northrop Grumman have postponed the planned arrival of the Cygnus XL cargo spacecraft at the International Space Station as mission teams work through an alternate approach to ensure a safe rendezvous with the orbiting outpost after an engine issue on the spacecraft. Originally scheduled to reach the station on Wednesday, September 17, Cygnus’s new arrival date is still under review.

The delay resulted from an issue early Tuesday morning when Cygnus XL’s main engine shut down earlier than expected during two planned orbital adjustment burns. These burns were critical to positioning the spacecraft for its approach to the ISS. Despite the premature shutdown, all other systems aboard Cygnus XL are functioning normally, according to NASA officials.

Cygnus XL is carrying over 11,000 pounds of scientific experiments, crew supplies, and hardware for the orbiting laboratory. NASA astronaut Jonny Kim is set to capture the vehicle using the space station’s Canadarm2 robotic arm, with NASA astronaut Zena Cardman serving as backup. Once secured, Cygnus will be berthed to the Earth-facing port of the Unity module, where it will remain until March 2026.

The vehicle launched at 6:11 PM ET on September 14 aboard a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station. The mission, designated Northrop Grumman Commercial Resupply Services 23 (CRS-23), is part of NASA’s ongoing partnership with commercial providers to maintain a steady flow of cargo and research to the ISS.

Flight controllers are currently evaluating an alternative trajectory plan to ensure a safe and successful docking in the coming days. NASA will provide updates as a revised schedule is confirmed.

SpaceX is planning to launch Falcon 9 and the Northrup-Grumman CRS-2 mission towards low Earth orbit and the International Space Station this evening. Shortly afterward, the Space Coast will hear a sonic boom as the booster returns to land at Cape Canaveral.

Launch time is scheduled for 6:11:48 PM ET in an instantaneous window. As is standard for most launches to Station, should weather or technical reasons prevent a launch at the time, SpaceX will be forced to stand down and wait for the next window tomorrow.

Payload

Tonight’s mission will be the Cygnus XL variant of Northrup-Gruman’s cargo delivery spacecraft. The XL is a “stretched” version that offers significantly more cargo volume and payload mass compared to earlier Cygnus versions. Specifically, it increases the cargo-carrying capacity by approximately 1,250 kg (roughly 33%) over the baseline, bringing its total payload capacity to around 5,000 kg (11,000 pounds) of pressurized cargo.

Among the research payloads are experiments for growing semiconductor crystals in microgravity, tools to refine technologies for cryogenic fuel tanks (which are critical for future space missions), and a UV light system designed to limit microbial growth in the station’s water systems. Also aboard are supplies for pharmaceutical crystal development with implications for cancer and other disease treatments. No ice cream this time, we checked and did not see it mentioned in NASA’s manifest.

Weather

Compared to other missions of late, the Launch Mission Execution Forecast from the 45th Weather Squadron of Space Launch Delta 45 is almost optimistic: 75% GO at launch time.

Trajectory

Northeast on the well-worn path to ISS:

Streaming Options

NASA will livestream the launch on NASA-TV. Coverage starts about 20-30 minutes before liftoff.

Spaceflight Now will have coverage of the launch starting about one hour before liftoff on Youtube: link

Please note that there is a delay between the launch stream and the actual countdown clock if you are watching in person. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.

For official updates regarding launch timesSpaceX.com is the best source of information. Starlink launch times change from time to time, and the company generally updates their website within minutes of the decision to change the launch time. This is very handy if none of the streaming options on YouTube have started their broadcasts.

Next Space Flight an app for iOS and Android phones, has a real-time countdown clock that is accurate to a second, give or take. The app is free. Search the App Store or Google Play. They are also available online at nextspaceflight.com.

Launch Viewing: In Person

Since the launch is during the early evening, a lot of options are available for spectators: Jetty Park, the Banana River Bridge on FL 528 W or the southern Titusville parks on Washington Avenue / US-1 are your best bets. Jetty Park will have the best view of the booster return, but not as spectacular a view of liftoff. On the other hand, Titusville parks will have the opposite: a great view of liftoff but not as close as Jetty Park for the landing.

Playalinda Beach is several miles north of the launch pad, but ignition and of course the flight of the rocket and its return are visible from that location. If you go, go early in case the crowds are heavy.

Other options include The Space Bar, a rooftop bar at the Courtyard By Marriott in Titusville. It offers great views of the launches and a full bar and menu. Other options include New York, New York on the Indian River in Titusville, but if you want to grab a bite, go early, because their kitchen usually closes for the day around 6:30 PM.

Vulcan Cert 2 liftoff

United Launch Alliance (ULA) is preparing to launch Vulcan on its first national security mission early next week from SLC-41 at Cape Canaveral Space Force Station. Scheduled for Tuesday, August 12, the USSF-106 mission will lift off from Cape Canaveral’s Space Launch Complex 41, carrying the U.S. Space Force’s Navigation Technology Satellite-3 (NTS-3) into geosynchronous orbit.

Mission DescriptionUSSF-106 is a U.S. Space Force mission deploying multiple payloads—including the NTS-3 (Navigation Technology Satellite 3), a demonstration satellite testing a reprogrammable digital signal generator to improve navigation resilience—directly into GEO using the new Vulcan Centaur VC4S rocket.

Launch dates and liftoff times are subject to change at any time.

USSF-106 will be Vulcan’s first operational flight, a milestone years in the making. ULA started work on the Vulcan family of rockets in 2014, and later the same year decided to use Blue Origin’s BE-4 methane-oxygen (methalox) engines. The decision was somewhat controversial at the time, given that Blue had not completed the final design of BE-4 much less started producing them at scale. It is ULA’s first rocket that the company has designed completely by itself.

This decision was a result of a way to move away from reliance on Russian RD-180 engines, which powered ULA’s Atlas V, and to ensure a domestically produced alternative for national security launches, and was mandated by Congress.

High Stakes for ULA

The mission is a key test not only of the rocket’s technical reliability but also of ULA’s ability to deliver on commitments that have been delayed by the vehicle’s troubled rollout. Military leaders, including Major General Stephen G. Purdy, have voiced frustration with setbacks that pushed back four major national security missions.

For ULA, this launch is more than just another flight; it is a chance to restore customer confidence after the near-disaster of Vulcan’s second certification mission last October. That launch succeeded in reaching orbit, but only after a solid rocket booster nozzle broke off mid-flight, causing asymmetric thrust that had to be corrected in real time by the in-flight software and by ground controllers. The incident raised concerns about the Vulcan’s Northrup Grumman-built GEM 63XL solid rocket motors, which lead to months of investigation and a test firing before certification for Vulcan was granted in March.

ULA holds a $5.3 billion contract to provide launch services through 2034, a lucrative and strategically important deal that depends on consistent, fault-free performance. A successful USSF-106 flight would help Vulcan’s place as a major part of the nation’s launch capability. A failure would put the company’s reputation and perhaps even government contracts in peril.

Northrop Grumman’s Mission Extension Vehicle-1 (MEV-1) has successfully concluded its first mission by undocking from Intelsat’s IS-901 satellite. This event marks the first-ever undocking between two commercial spacecraft in the geosynchronous Earth orbit (GEO) graveyard, setting a new precedent in orbital servicing operations.

A video provided by Intelsat explains:

Launched in 2001, IS-901 was nearing the end of its operational life when MEV-1 docked with it in February 2020 in the satellite “graveyard.” This graveyard orbit is typically about 300 kilometers above the geostationary orbit and exists to minimize interference with active satellites.

The MEV-1 provided propulsion and attitude control, effectively extending the satellite’s service life by five years. After completing its mission, MEV-1 maneuvered IS-901 back to the GEO graveyard orbit and undocked on April 9, 2025, with the MEV-1 mission continuing.

Rob Hauge, president of Space Logistics LLC, a Northrop Grumman subsidiary, highlighted the significance of this mission: “The first-of-its-kind technology that extended a satellite’s life is paving the way for an entire infrastructure of future on-orbit satellite servicing missions for a variety of customers.”

Following this success, MEV-1 is set to embark on its next mission, and to continue demonstrating the viability of in-orbit servicing. Meanwhile, MEV-2 remains docked with Intelsat 10-02, providing life-extension services that have been extended by an additional four years beyond the original contract.

These advancements in satellite servicing technologies are poised to revolutionize the management of space assets, offering solutions for repairs, upgrades, refueling, debris removal, and more. These developments are crucial for enhancing the longevity and sustainability of satellites in orbit and reducing costs by providing longer lifespans for orbital assets.

After a picture-perfect launch Sunday morning, Northrup Grumman’s Cygnus CRS-2 NG-21 (S.S. Francis R. “Dick” Scobee) spacecraft encountered issues with its solar power array and its single engine.

NASA announced yesterday that there were issues with the solar arrays that powered the spacecraft, and that it had burned its first orbital correction engine burn intended to put Cygnus on a path towards ISS.

The solar array issue has been rectified, according to NASA

Northrop Grumman’s Cygnus spacecraft completed the deployment of its two solar arrays at 2:21 p.m. EDT after launching at 11:02 a.m. Aug. 4 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida to the International Space Station for NASA.

NASA, August 4, 2024

Of equal concern is a problem with Cygnus’s engine, which experienced low pressure during its planned firing:

Shortly after launch, the spacecraft missed its first burn slated for 11:44 a.m. due to a late entry to burn sequencing. Known as the targeted altitude burn, or TB1, it was rescheduled for 12:34 p.m., but aborted the maneuver shortly after the engine ignited due to a slightly low initial pressure state. There is no indication the engine itself has any problem at this time.

Cygnus is at a safe altitude, and Northrop Grumman engineers are working a new burn and trajectory plan. The team aims to achieve the spacecraft’s original capture time on station, which is currently slated for 3:10 a.m. on Tuesday, Aug. 6.

August 5 Update From NASA, Dr. Jonathon McDowell and NASA

Around 3PM EDT, NASA gave the following update:

Northrop Grumman’s Cygnus spacecraft continues on its way to the International Space Station following launch at 11:02 a.m. EDT Aug. 4 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The Cygnus spacecraft completed the deployment of its two solar arrays at 2:21 p.m. the same day.

The Cygnus spacecraft has completed two delta velocity burns, and it remains on track for a capture by the space station’s robotic arm slated for 3:10 a.m. on Tuesday, Aug. 6. The spacecraft is in a safe trajectory, and all other systems are operating normally.

Shortly after launch on Sunday, the spacecraft performed as designed by cancelling a scheduled engine burn due to a slightly low initial pressure reading flagged by the Cygnus onboard detection system. Engineers at Northrop Grumman’s mission control center in Dulles, Virginia evaluated the pressure reading, confirmed it was acceptable and re-worked the burn plan to arrive at the space station on the originally planned schedule.

NASA, August 5, 2024

Dr. Jonathon McDowell of the Harvard–Smithsonian Center for Astrophysics and perhaps the most authoritative source concerning orbital objects also offered this update shortly after three today.

From all appearances, Northrup Grumman, IHI Aerospace and NASA have rectified the issues that seemed to imperil the NG-21 mission on its first full day in space. Hopefully, Cygnus’s problems are behind it, and the spacecraft will bring some much-needed supplies and items to ISS as planned.

About Cygnus’s Engine

Cygnus is an American cargo spacecraft designed for expendable logistics missions to the International Space Station (ISS). It features two main components: the Service Module (SM) and the Pressurized Cargo Module (PCM). The Service Module includes 32 thrusters for attitude control and a BT-4 main engine, which burns 800 kg (1,800 lb) of hypergolic propellants—hydrazine and nitrogen tetroxide.

Update: 12 PM EDT Saturday

A wave of thunderstorms passed through the Cape Canaveral area around 90 minutes before liftoff Saturday, forcing SpaceX to stand down from its launch attempt today.

The company said in a latter post on X.com that they would try again tomorrow, but with a 90% Probability of Violation and an approaching tropical system off of Florida’s west coast, the chances of that don’t seem very high. Monday’s forecast is equally squirrelly as the system is forecast to arc through northern Florida, creating storm squalls and windy conditions across the state.

On the other hand, it’s Florida and the weather here can be unpredictable. So, we’ll see when SpaceX can get this launch off of the pad.

—————-

SpaceX is planning to launch Falcon 9 carrying the NG-21 ISS Resupply mission for Northrup Grumman. Liftoff Saturday morning is set 11:28 AM EDT (1538Z) in an instantaneous window from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

SpaceX plans for the booster to return and land at Landing Zone 1 in Cape Canaveral. The Space Coast will hear a sonic boom from the booster as it herald’s its return, which should happen approximately 7.5 minutes after liftoff.

Weather is a major concern for this launch, as a tropical disturbance’s passing to the west in the Gulf of Mexico is expected to bring heavy rains to the Space Coast over the weekend. Current forecasts are calling for weather to arrive sometime Saturday, so the timing of the storm coupled with the normal storm activity of Florida in summer leaves forecasters calling the chances of acceptable weather a coin flip with a 50% chance of a Probability of Violation at launch time.

According to NASA, the payload includes:

  • Test articles to evaluate liquid and gas flow through porous media found in space station life support systems.
  • balloon, penny, and hexnut for a new STEMonstration on centripetal force.
  • Microorganisms known as Rotifers to examine the effects of spaceflight on DNA repair mechanisms.
  • bioreactor to demonstrate the production of many high-quality blood and immune stem cells.
  • Vascularized liver tissue to analyze the development of blood vessels in engineered tissue flown to the space station.

Weather

General Forecast

The forecast at launch time looks relatively benign:

Temperature28.9°C
Humidity~65%
PrecipitationNone, Probably
Cloud coverVariable
Windspeed (at ground level)10-15 MPH / 4.5-6.7 m/s
Visibility~16.5 miles / 27.0 km

Official Launch Forecast

The 45th Weather Squadron’s discussion in their launch forecast mentions the tropical system noted above. “All eyes will remain on Potential Tropical Cyclone Four (PTC 4) as it lifts out of the Greater Antilles and into the Gulf of Mexico. The official forecast from the National Hurricane Center has the system becoming a named storm Saturday and skirting the western Florida Peninsula Sunday, potentially making landfall as a Tropical Storm anywhere from the Florida Big Bend to southwest Florida.

Regardless of where the center of the storm makes landfall, the Space Coast will be on the eastern side of the system, and weather is likely to deteriorate with time from Saturday afternoon into Sunday. For the initial launch window, scattered showers are expected to approach the coastline out of the southeast and potentially move onshore.”

Their primary concerns that could necessitate a delay are: the Cumulus Cloud Rule, Surface Electric Fields Rule, and Thick Cloud Layers Rule.

Online Viewing

SpaceCoastLaunchCalendar.com will have a livestream of the launch if you’re not able to watch the launch in person: Livestream

SpaceX will have a livestream of the launch on their website: NG-21 Mission. This will also be available on the X platform. Coverage starts about five minutes before liftoff.

NASA’s launch coverage begins at 11:00 AM EDT on NASA+, NASA Television, the NASA appYouTube, and the agency’s website.

Spaceflight Now will have coverage of the launch starting about one hour before liftoff on Youtube: link

For official updates regarding launch timesSpaceX.com is the best source of information. Starlink launch times change from time to time, and the company generally updates their website within minutes of the decision to change the launch time. This is very handy if none of the streaming options on YouTube have started their broadcasts.

Remember that there is a delay between a launch stream and the actual countdown clock. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.

Next Space Flight an app for iOS and Android phones, has a real-time countdown clock that is accurate to a second, give or take. The app is free. Search the App Store or Google Play. They are also on the web: nextspaceflight.com.

Launch Viewing: In Person

This morning’s planned launch is from SLC-40 at Cape Canaveral, which means that the best direct views of liftoff are: 

Banana River Bridge on FL-528 W near Port Canaveral, where you will be able to see ignition, liftoff and the booster landing. Free.

Kennedy Space Center Vistor’s Center. From Apollo/Saturn V Center. Premium Launch Transportation Ticket. Bleacher seating is available, expert commentary, and closer view of the launch from across Banana Creek. Landing is pretty far away, relatively speaking. $70 for the launch viewing ticket plus entrance fees and parking. If you choose this go very early — lines will be long!

The southern parks on US-1 / S. Washington Avenue in Titusville. Kennedy Point Park and Rotary Riverview Park (among others) are your best bets for free viewing sites. These sites will be great for the launch, but not as good for the landing.

Indirect Views

There are several excellent viewing spots for SLC-40 launches that offer indirect views — meaning you won’t see the rocket until it clears obstructions such as trees, buildings, even a storm berm in one case.

  • Jetty Park, Port Canaveral
    • Fee required, much be purchased in advance: Port Canaveral Store
    • It’s very possible to see a cruise ship coming or going.
    • The pier especially has great views of the landing — probably the best that the public can get to. The launch view is indirect.
  • Cocoa Beach
    • Parking fees (probably). Pay with your smartphone on the parking app. There are signs everywhere telling you how.
    • Further away, but still good views. Launch and landing is indirect.
  • Northern Titusville Parks
    • Further away, but really nice views after liftoff.
    • You won’t see the landing directly, but instead from a good distance away.

Restaurants With Good Launch Views

  • The Space Bar ($$$) – atop the Courtyard Marriott near Kennedy Parkway
  • New York New York ($$) – on the Indian River with an outdoor seating area. Is family-friendly.
  • Shiloh’s ($$$) — located on the Indian River with an outdoor deck overlooking KSC/CCSFS

Playalinda Beach

Playalinda Beach out on the Cape Canaveral National Seashore should be open to spectators until 8 PM EDT, that is if KSC Security and the National Park Service allow viewers for the launch. Generally, they have been, but security concerns can differ for each launch. It opens to visitors at 6 AM.

This is a popular place, so if you go, go early.

Call ahead to be sure they are open..

Cape Canaveral National Seashore • Playalinda Beach
Phone: (386) 428-3384 x0

Current operating hours: 6:00 AM–8:00 PM

If you are going to Playalinda, and if it is open, remember these general tips. Some may not apply to this particular launch.

  • Get there at least two hours early, or better, earlier than that. Lines are long at the entry gate and they will only allow as many spectator vehicles as there are parking space available.
  • Cape Canaveral National Seashore has a fee to get in and cash is not accepted. Debit and credit cards are okay, or if you have one of the National Park Service’s passes for the Seashore or the National Parks, that will work as well.
  • Cellphone service is spotty at best and often non-existent at Playalinda. Don’t count on your cellphone to keep up with the launch; you might get a signal, or you might not.
  • You are not allowed to view from the pullouts on Beach Road. Stanchions will block them. You’ll have to park and go to the beach.
  • Refreshments are not available. There are no stores at Cape Canaveral National Seashore, so you’ll need to bring drinks and food if you want any while you’re there.
  • Rangers will keep you back a certain distance from the launch area on the beach. Even if the beach is open, you’ll still be unable to go down to the fence that demarcates the normal security zone. There’s a line that spectators can’t go past somewhat north of the fence. That’s for safety and security.

Be prepared for potential changes or pushbacks in the launch schedule, and keep up by monitoring the live stream links mentioned above.

Booster: B0180

SpaceX states on their website, “This is the tenth flight of the first stage booster supporting this mission, which previously launched Ax-2, Euclid, Ax-3, CRS-30, SES ASTRA 1P, and four Starlink missions.”
