Falcon 9

SpaceX Kuiper KF-03

After multiple delays due to weather, the skies cooperated this evening for SpaceX, allowing the company to launch Falcon 9 and 24 Kuiper telecommunications satellites for Amazon. Liftoff was at 9:58 PM ET.

After flying straight and true throughout its part of the mission, after staging, Booster B1091-2 landed aboard ASDS ‘A Shortfall of Gravitas’ downrange in the Atlantic Ocean off of the coast of the Carolinas at T+ 00:08:18 of the flight.

Meanwhile the second stage and payload continued their ascent until the T+08:30:00 mark when the first second stage shutdown occurred. Another burn is scheduled for the T+00:52:50 mark, and payload deployment is slated to begin shortly after that.

This was the third and final mission for Project Kuiper hardware to launch aboard a Falcon 9, and SpaceX’s 133rd mission for 2025. All-time, SpaceX has flown 546 missions.

Payload

Amazon now has 153 Kuiper spacecraft in orbit.

The Kuiper project is Amazon’s initiative to provide broadband internet service through a constellation of satellites. Today’s launch is the sixth of a series that aims to meet the conditions set by the Federal Communications Commission, which require half of the planned 3,236 satellites to be in orbit by mid-2026. The full network is expected to be completed by mid-2029.

Amazon has publicly committed more than $10 billion to the development and deployment of the Kuiper constellation. The company is building out supporting infrastructure in tandem with the satellites, including user terminals and ground communication sites. The terminals, developed in-house, are designed to be compact and cost-effective. Amazon has said these terminals will support download speeds up to 400 Mbps and will be priced under $400, though full commercial service has not yet begun.

Starlink launching in 2023 from SLC-40 in Cape Canaveral.

SpaceX is planning to launch another tranche of Kuiper satellites for Amazon from Space Launch Complex 40 at Cape Canaveral Space Force Station Monday evening after weather delays stopped previous attempts last week. The current launch window opens at 08:08 PM ET (0008 Z), and closes at 10:22:00 PM the same day. Weather here at the launch site is all but perfect, but out at sea, conditions in the expected booster landing area will remain a concern for at least another couple of days.

After launching and powering the initial ascent phase for the mission, Booster 1091-2 will complete its second mission by landing on ASDS  ‘Just Read the Instructions’, which is stationed downrange in the Atlantic Ocean.

Should it be required, a backup launch opportunity is available on Tuesday, October 14 starting at 7:46:00 PM ET.

Weather

The 45th Weather Squadron of the US Space Force’s Launch Delta 45 has forecast a 95% chance of acceptable conditions at The Cape, and they have also outlined concerns in the booster recovery area.

Trajectory

The vehicle is expected to insert its payloads into a roughly 630 km altitude, 52° inclination orbit — the same operational orbit used for prior Kuiper launches.

Payload

Tonight’s launch carries 24 Kuiper satellites, built for Amazon’s Project Kuiper constellation. These spacecraft are designed for broadband internet delivery, each outfitted with advanced phased-array antennas and inter-satellite laser links to route data across the network.

Together, they will bolster a growing low Earth orbit (LEO) broadband mesh that Amazon aims will eventually consist of over 3,200 satellites to provide global high-speed internet access.

Once in service, these 24 new Kuiper satellites will add capacity and redundancy to the live network. They’re expected to support continuous global coverage in coordination with previously launched Kuiper craft, making the network more robust against outages or orbital anomalies.

SpaceX and NASA launched the IMAP Rideshare mission early Wednesday morning from Launch Complex 39A at Kennedy Space Center. After an apparently event-free countdown, liftoff was at 07:30 AM ET.

The flight appeared to be nominal, and Falcon 9 entered into a parking orbit around eight minutes after liftoff. The rocket and payload are now in a coast phase prior to to payload deployment, after which the three scientific satellites carried to orbit this morning will make their own way to the Lagrange 1 point, about one million miles from the Earth in the direction of the Sun.

About 7.5 minutes after liftoff, Booster B1096 touched down safely downrange aboard ASDS ‘Just Read The Instructions.’ Both barge and booster will now return to Port Canaveral, after which the booster will be offloaded and transported to SpaceX’s Hangar X facility at Kennedy Space Center, where it will be inspected, refurbished as necessary and prepared for its next mission.

Payload

Three space weather satellites were launched this morning: the NASA IMAPCarruthers Geocorona Observatory and the NOAA) Space Weather Follow On – Lagrange 1 (SWFO-L1) instruments.

IMAP (Interstellar Mapping and Acceleration Probe) is designed to study the boundary of the heliosphere, a bubble-like region of space dominated by the solar wind. Positioned about one million miles from Earth at the L1 Lagrange point, IMAP will capture and analyze particles that stream into the solar system from interstellar space. Its goal is to map how the solar wind interacts with the interstellar medium, shedding light on how cosmic rays are filtered and how the heliosphere protects our solar system from galactic radiation.

SWFO (Space Weather Follow-On) is a NOAA satellite mission focused on monitoring solar activity that could impact Earth’s space environment. Scheduled to launch alongside IMAP, SWFO will also be stationed at L1, where it will provide continuous data on solar wind, magnetic fields, and solar energetic particles. Its primary purpose is to support real-time space weather forecasting, helping to protect satellites, power grids, GPS, and other technologies from solar storms and other space weather events.

Carruthers Geocorona Observatory is a NASA mission named after astrophysicist George Carruthers, aimed at studying the outermost layer of Earth’s atmosphere—the geocorona. This layer of hydrogen extends thousands of miles into space, and Carruthers will observe it in ultraviolet light to understand how Earth’s atmosphere escapes into space and interacts with solar radiation. By providing detailed imaging of the geocorona, the probe will help scientists refine models of atmospheric loss, which has implications for both Earth and exoplanet habitability studies.

The fully assembled Carruthers Geocorona Observatory at AstroTech in Titusville earlier this month.

The Carruthers Geocorona Observatory is one of NASA’s newest Earth-facing space weather missions, named in honor of the late George Carruthers, a pioneering astrophysicist who built the first lunar-based telescope as part of the Apollo 16 mission.

What Will This Observatory Measure?

The observatory’s mission is to image the geocorona, a vast cloud of hydrogen atoms that extends tens of thousands of miles beyond Earth’s atmosphere. Also called the exosphere, it is invisible to the naked eye. The geocorona’s hydrogen halo interacts with solar radiation and can be measured to monitor how solar activity affects Earth’s environment.

The Carruthers Observatory uses ultraviolet (UV) imaging to observe how the geocorona responds to solar emissions, particularly during solar storms. By watching the movement and intensity of hydrogen glow in the far-UV spectrum, scientists can get early indicators of incoming disturbances from the Sun.

“Carruthers gives us a front-row seat to the very edge of Earth’s atmospheric bubble,” said Nicola Fox, associate administrator for NASA’s Science Mission Directorate. “It’s a critical piece in understanding how Earth responds to solar energy.”

Heading To L1

After launch, the telescope will travel to the L1, or the first Lagrange Point, which is relatively near the Earth — about one million miles away. L1 is the point of gravitational equilibrium between the Earth and the Sun, and that region provides a stable position for small objects to reside while using a minimum amount of fuel to remain there. Several scientific payloads, such as the Solar and Heliospheric Observatory (SOHO) also reside in the region.

Lagrange-1, or L1, lays about a million miles from Earth in the direction of the Sun. This is about four times the distance from Earth to Moon. Graphic adapted from a NOAA original.

Carruthers will be able to directly measure the size of Earth’s geocorona for the first time. The first Carruthers telescope landed on the moon, too close to see the geocorona in its entirety. That said, this mission will enable scientists to measure the size of Earth’s atmosphere for the first time.

The spacecraft is part of the IMAP Rideshare mission, which will launch tomorrow Wednesday.

Weather

Not great, but improving: the Space Force’s 45th Weather Squadron of Launch Delta 45 is calling for a 40->60% probability of acceptable weather. Essentially, they are saying that weather will improve through the launch window — it will be 40% at 8:00pm and by the end of the window that will increase to 60%.

Of course, that’s just a forecast, and the launch probabilities will be calculated continuously through the launch window until Falcon 9 lifts off or SpaceX calls off the launch.

A final environmental assessment approved by the Federal Aviation Administration (FAA) clears the path for SpaceX to build and operate a Falcon 9 rocket landing zone at Space Launch Complex 40 at Cape Canaveral Space Force Station.

NOTE: this is not either one of the two Starship EA currently underway for the Eastern Range.

The assessment also supports an increase in the number of annual Falcon 9 launches from SLC-40, raising the cap from 50 to 120 per year. The FAA’s decision, finalized in August 2025, comes after months of federal coordination, public comment, and technical review.

The document is below, and it can also be downloaded from the FAA website: SpaceX Falcon 9 Operations at Space Launch Complex-40.

FAA Approval Enables New Landing Zone, Expanded Launch Schedule

The FAA, acting as the lead federal agency, reviewed SpaceX’s proposal to both increase the number of Falcon 9 launches and construct a 400-foot-diameter concrete landing pad east of the SLC-40 pad. According to the final Environmental Assessment (EA), the FAA concluded that the project would not cause significant adverse environmental impacts.

With this approval, SpaceX may now move forward in seeking:

  • A modification to its current launch license (LLO 18-105),
  • A potential new launch license under 14 CFR Part 450, and
  • Airspace closure approvals for each launch and landing.

The FAA emphasized that environmental clearance does not automatically guarantee license approval but does permit further steps toward that end.

Construction of the new landing zone will occur within a 10-acre lease boundary adjacent to the existing launch site. The landing zone includes a concrete pad, gravel apron, nitrogen gas line, processing pedestal, and associated infrastructure.

Environmental Effects

Water & Wetlands

The final EA identified that the construction and operation of the new landing site will affect several protected habitats and species, notably the Florida scrub-jay and Southeastern beach mouse. In consultation with the U.S. Fish and Wildlife Service, a Biological Opinion concluded the project “is not likely to jeopardize” listed species or critical habitats, provided mitigation measures are followed. Those measures include habitat compensation and best management practices during construction.

Noise and Sonic Booms

Noise impacts—especially those resulting from rocket landings—were analyzed in detail. Falcon 9 landings at Cape Canaveral generate sonic booms, but the FAA determined that their frequency and intensity fall within previously analyzed limits. Up to 34 landings annually are expected to take place at the new SLC-40 site. Downrange ocean landings using drone ships will continue for the remainder.

The EA also confirmed that sonic boom pressure levels from the new landing zone would be comparable to existing operations at LZ-1 and LZ-2. Noise levels would be highest during landings but occur infrequently enough that they do not trigger significant regulatory thresholds under federal guidance.

Public Input

The FAA received more than 4,000 public comments during the review period for the draft EA. Public engagement included virtual meetings, local newspaper notices, and hard copies of the document being distributed to several Brevard County libraries.

According the FAA, most comments expressed support or posed technical questions, with at least one requesting that the FAA produce a full Environmental Impact Statement (EIS), citing concerns about cumulative effects and development intensity. The FAA opted to finalize the EA instead, citing that the expected impacts did not reach the threshold requiring a more extensive EIS process.

No substantial objections were raised by local municipalities or regulatory agencies. The Florida Department of Environmental Protection, for instance, found the project consistent with the Florida Coastal Management Program.

With the EA finalized and a Finding of No Significant Impact (FONSI) likely, the next phase will involve regulatory and operational coordination:

CRS-33 launches aboard Falcon 9

SpaceX launched Falcon 9 from Space Launch Complex 40 at Cape Canaveral overnight, sending supplies to the International Space Station aboard Cargo Dragon. Liftoff was at 02:45 AM ET into partly cloudy skies.

Tonight’s launch was the seventh for Booster 1090, which landed safely aboard ‘A Shortfall of Gravitas’ some eight minutes and forty seconds after liftoff. ‘ASOG’ will now return to Port Canaveral, where the booster will be unloaded and transported to SpaceX’s Hangar X for inspection, refurbishment and preparation for its next mission.

At T+08:47, Cargo Dragon achieved its initial orbit, and less than a minute later, it separated from Falcon 9’s second stage and began to make its way to the International Space Station, where it is expected to dock tomorrow morning.

Cargo

Food, supplies, hardware and new scientific experiments make up the bulk of the cargo being carried to ISS. For more specifcs, consult our Launch Preview article.
