Mission Description 33rd commercial resupply services mission to the International Space Station operated by SpaceX. The flight will be conducted under the second Commercial Resupply Services contract with NASA.

Cargo Dragon 2 brings supplies and payloads, including critical materials to directly support science and research investigations that occur onboard the orbiting laboratory.

As of 10:00 AM Saturday August 23, 2025. Launch times are subject to change or cancellation at any time. Consult SpaceX.com for more information.

Along with the usual gamut of food, gear, and crew supplies, CRS-33 will deliver a range of scientific experiments to the International Space Station. These include stem cells that promote bone formation, aimed at studying how to prevent bone loss in space. Dragon will also carry materials for 3D printing medical implants—research that could lead to better treatments for nerve damage back on Earth.

The Tortilla Express

Another item on the launch manifest for CRS-33 is roughly 1500 tortillas. They are a staple food aboard Station — convenient, quick, and quite handy to bundle up other food items…breakfast, lunch or dinner. They are a crumb-free condensed item, making the humble tortilla one of the most likely foods humans will carry to Mars and beyond.

Other payloads include bioprinted liver tissue for examining how blood vessels form in microgravity, and tools for printing metal cubes in orbit.

Planned Reboost Test For Cargo Dragon

Cargo Dragon will also conduct a reboost test to help maintain the station’s altitude. The boost system, housed in Dragon’s trunk, features its own propellant setup and uses a pair of Draco engines powered by existing hardware.

Starting in September 2025, the system will carry out a series of burns to demonstrate its ability to sustain the lab’s orbit. This follows Dragon’s first successful test of the reboost function on November 8, 2024, during NASA’s 31st commercial resupply mission with SpaceX.

Cargo Dragon is expected to stay docked at the station through December after which it will return to Earth off of the coast of California.

Booster: B1090

This will be the seventh flight of first stage B1090, which will be supporting this mission. Previously, B1090 launched O3b mPOWER-E, Crew-10, Bandwagon-3, O3b mPOWER-D, and two Starlink missions. Following stage separation, it will land on the A Shortfall of Gravitas, located downrange off the South Carolina coast. There will not be a sonic boom on the Space Coast after the launch.

Weather

The 45th Weather Squadron of Space Launch Delta 45 released their Launch Mission Execution Forecast yesterday afternoon, and it calls for a 70% chance of acceptable weather, with watch items being the usual summer items: cumulus clouds and nearby lightning.

Trajectory

Northeast, on the usual ISS route.

B1090 will touch down off the South Carolina coast aboard ‘A Shortfall of Gravitas.’

SpaceX USSF-36 OTV-8

SpaceX launched their 101st Falcon 9 mission of 2025 last night from Kennedy Space Center when the company sent the Boeing X-37 space plane to low Earth orbit on a classified mission. Liftoff was at 11:50 PM EDT, shortly after the opening of the launch window.

Following a “norminal” initial ascent and stage separation, Falcon 9 first-stage booster B1092 touched down at Landing Zone 2 at Cape Canaveral Space Force Station, concluding its sixth flight successfully about 8 miles away from its starting point. This booster previously launched NROL-69, CRS-32, GPS III-7, and two Starlink missions and will soon be transported for refurbishment at SpaceX’s Hangar X facility at Kennedy Space Center.

Payload

The X-37B Orbital Test Vehicle (OTV) is a reusable, uncrewed spaceplane developed by Boeing for the United States Space Force. Roughly the size of a small bus, it resembles a miniature space shuttle orbiter and operates in low Earth orbit for extended missions—some lasting over 900 days.

As Space Coast skies faded into night, United Launch Alliance launched their Vulcan-Centaur rocket from Space Launch Complex-41 at 7:59 PM Eastern Time, carrying the classified USSF-106 mission for the U.S. Space Force. The evening launch, near the end of the one-hour window, was a successful return for the vehicle after its near-catastrophic solid rocket failure in its last launch in October, 2024.

United Launch Alliance (ULA) launched its Vulcan-Centaur rocket from LC-41 at Cape Canaveral Space Force Station carrying the the USSF‑106 mission Tuesday night. Liftoff was at 8:56 PM ET, close to the end of the launch window and into partly cloudy skies, as the usual summer storms were mostly west of the Cape and far away enough to present no problem for the launch team.

This was Vulcan-Centaur’s first operational mission and the first national security payload to utilize its services, a milestone ULA has been working toward since 2014. ULA has faced scrutiny over Vulcan, with military officials calling for more reliability and accountability as the company shifts gearsto its new fleet. There are no more Delta-family launches left, and a dwindling number of Atlas-V launches, most of which are planned for Amazon’s Kuiper Project as well as the Boeing Starliner program.

The DoD awarded ULA a multibillion‑dollar contract in April 2025, securing 19 missions through 2034 under the NSSL Phase 2 procurement. Having completed its certification for National Security Space Launch (NSSL) missions, Vulcan-Centaur and ULA join SpaceX as one of only two providers cleared to carry critical U.S. military and intelligence assets.

“National security begins at liftoff,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “Vulcan did exactly what it was built to do: deliver a critical mission with power, precision and confidence. We are proud to play a role in strengthening the nation’s space capabilities.”

Two methane‑fueled Blue Origin BE‑4 engines power Vulcan Centaur’s core stage, and for this mission, it was equipped with four Northrop Grumman GEM 63XL solid rocket boosters. Two L3 Harris Rocketdyne RL‑10 engines power the second stage, making Vulcan-Centaur a powerful workhorse for the company as it moves into the future.

Payload

The centerpiece of USSF‑106 is the Navigation Technology Satellite‑3 (NTS‑3) a pioneering PNT (position, navigation, and timing) satellite developed by the Air Force Research Laboratory. It’s the first experimental navigation satellite launched by the U.S. military in nearly half a century—a milestone with huge implications for future secure and adaptive navigation systems.

Also aboard USSF-106 was another undisclosed payload, and requests to the Space Force for any additional information were not granted. That’s the nature of classified payloads, and the fewer questions asked the better.

A small jellyfish seen behind an Atlas V

United Launch Alliance (ULA) is gearing up for a Vulcan launch tonight from SLC-41, USSF-106. Liftoff is set between 7:59 and 8:59 p.m. Eastern Daylight Time (2359–0059 UTC). And, if weather and timing permits, the launch may come with a bonus: a jellyfish plume, one of the most spectacular sights a launch spectator can see.

The weather looks favorable, with an 80% chance of conditions being acceptable through the launch window. The primary concerns include cumulus clouds, lightning potential, and surface electric fields. This is of course a common scenario for late-afternoon summer launches on the Space Coast. Final launch preparations by ULA and the Space Force, including the launch vehicle readiness review, are complete and “GO” for tonight.

Launch Time Is Near Local Sunset

If the skies cooperate and if the timing is just right, one of tonight’s most awe-inducing side effects could be a “space jellyfish”, a glowing, jellyfish-shaped plume formed by sunlight illuminating rocket exhaust at high altitude, while the ground below remains in twilight or darkness.

Here’s how it works:

  • Timing is critical: Launching during twilight means the rocket ascends into sunlight while observers are in shadow. That’s because on the ground, the sun is below the horizon but is still visible in the ultra high altitudes a rocket travels through on its way to space. That’s simple geometry: the angle to the horizon is different for the rocket.
  • Clear Skies: If low clouds are between the spectator and the rocket, they won’t see much.
  • High-altitude expansion: If you have seen only a few launches, you probably remember the phase towards the end of the first stage’s part of the flight where gases spread into a broad, diffuse cloud that forms a conical shape behind the rocket. This is not the Max-Q contrail, something common to most rockets, instead, it happens very high in the sky when the rocket’s is mostly outside of Earth’s atmosphere.
  • Optical spectacle: Because it is still in sunlight, the rocket plume is an illuminated cloud that takes on a jellyfish-like shapes, maybe with tendrils trailing behind, formed by thinner exhaust streams.
  • Darkness: the relative contrast between the ground and the sky makes this phenomenon highly visible to launch spectators.

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.

The small shower that soaked SpaceX’s Falcon 9 during the last two minutes of the terminal count today at the Cape. They will try again tomorrow.
Photo: Charles Boyer / Talk of Titusville

A popup shower over the launch pad soaked another SpaceX launch at the last minute today, forcing a scrub of their launch of Falcon 9 carrying the Kuiper KF-02 mission from Space Launch Complex 40 with about 29 seconds remaining before liftoff. The company online announced that it will try again tomorrow. Lather, rinse, repeat.

This scrub was a near repeat of the Jul 31st attempt to launch Crew 11 from LC-39A up at Kennedy: everything was great until it wasn’t. Both launch attempts ended abruptly, as the scrubs came with only seconds remaining on the countdown clock.

Because SpaceX uses densified propellants, once the rocket is fueled, it must launch — or not — on time. If it doesn’t, the launch is scrubbed, and the rocket is defueled for the day.

Summers are like that on the Space Coast. A single cloud can pop up at any time and stop a countdown. Locals shrug and go about their day, but tourists cross their fingers and hope that their luck holds out. Today it didn’t.

SpaceX continued adding to its Starlink constellation last night when it sent another group of 28 Mini V2 satellites to orbit late last evening. Dubbed Starlink 10-29, liftoff was at 11:37 PM ET from Space Launch Complex 40 at Cape Canaveral Space Force Station.

Booster B1069 flew for the 26th time during the mission, and afterwards, it landed offshore aboard ASDS ‘Just Read The Instructions,’ one of SpaceX’s two automated landing platforms assigned to the Eastern Range. B1069 and ‘JRTI’ will now return to Port Canaveral, where the booster will be offloaded and transported to SpaceX’s Hangar X facility at Kennedy Space Center. There it will be refurbished and prepared for its next flight.

A SpaceX Falcon 9 awaiting launch at SLC-40 in Cape Canaveral

SpaceX is set to launch Falcon 9 and the SES-operated O3b mPower satellites this evening from Space Launch Complex 40 at Cape Canaveral. Liftoff is set for 05:12 PM ET, with a two hour window extending to 07:12 PM ET.

Official weather forecasts have given the mission a 50/50 chance for acceptable weather, with roughly a 25% chance of thunderstorms in the launch area during the launch window. Keep in mind that acceptable conditions consider more than just rain, it also includes thunderstorm activity in the launch area as well as the lightning potential in the immediate vicinity of the rocket. To learn more about launch commit criteria, click here.

Boeing’s 9th and 10th O3b mPOWER satellites—launched in partnership with SES—will bolster the company’s push to deliver global connectivity from space. Leveraging Boeing’s fully software-defined payload technology, these satellites can dynamically allocate power to match user demand.

Today will mark the sixth mission for Falcon 9 first stage booster B1096, and after completing its share of the mission, the booster will touch down offshore on ASDS ‘Just Read The Instructions.’
