SpaceX is requesting permission from regulators to turn its ocean-based rocket landing pads into satellite ground stations.

First reported by Advanced Television, the satellite company has filed for permission with the FCC to test its Starlink antennas aboard its ocean-based rocket landing platforms, known as autonomous spaceport drone ships (ASDS).

The company has requested Special Temporary Authority to operate up to twelve Ka-Band earth stations operating aboard autonomous drone ships in US waters in the North Atlantic Ocean and Pacific Ocean. The east stations will communicate with SpaceX satellites.

SpaceX would operate no more than four earth stations per vessel under this authorization at any given time, the company said. This experiment will enable SpaceX to test antennas onboard SpaceXs autonomous drone ships in the Ka-band.

The trial would run until June 29, 2024. A second SpaceX document added: The purpose of the test is to assess the earth stations' ability to serve as gateways in a maritime environment using test traffic. For the purposes of this experiment, SpaceX seeks to connect earth stations with its first- and second-generation satellite systems in the Ka-band. During the test period, the earth station will only receive and transmit test traffic to assess the capability of these earth stations to route and switch NGSO FSS traffic and backhaul local networks in a maritime environment.

SpaceX first announced plans for unmanned floating landing platforms back in 2014. The companys reusable rockets launch from and land on the barges, and the platforms autonomously keep station using GPS. Current and former platforms used by SpaceX include Just Read the Instructions 1 and 2, Of Course I Still Love You, and A Shortfall of Gravitas. All are based on the Marmac series of barges from McDonough Marine Service.

Starlink has signed a number of connectivity deals in the maritime sector. Container ship companies including Fukujin Kisen, Hapag-Lloyd, Seaspan Corporation, Polembros Shipping, Columbia Shipmanagement, Costamare, Sun Enterprises, F. and Laeisz are Starlink customers.

Cruise liner firms deploying Starlink terminals include Ambassador, Cunard, Seabourn, Aqua Expedition, OceanGate Expeditions, Enesel, Royal Caribbean, Norwegian Cruise Line, Carnival Corporation, Windstar Cruises, Hurtigruten, SeaDeam, and American Cruise Line.

On the week of the sixth anniversary of the first flight of Falcon Heavy, SpaceX looks to launch four separate Falcon 9 missions. Meanwhile, JAXA is preparing for the second flight of the H3 rocket after its unsuccessful maiden launch in 2023, while Roscosmos will resupply the International Space Station (ISS) with Progress MS-26 launching on Soyuz.

On Tuesday evening, this weeks first batch of Starlink satellites was supposed to launch on a SpaceX Falcon 9 from SLC-4E at Vandenberg Space Force Base (VSFB) in California but that was scrubbed due to bad weather. Early Thursday morning, another Falcon 9 launched from SLC-40 at the Cape Canaveral Space Force Station (CCSFS) taking NASAs Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Earth-observing satellite to a Sun-synchronous orbit (SSO). Later in the week, SpaceX will launch again from SLC-40 taking another group of Starlink satellites to low-Earth orbit.

Closing out this extended week, there will be a triple header of launches coming from three different countries. The first will be SpaceXs launch of the IM-1 Nova-C lunar lander out of LC-39A at the Kennedy Space Center (KSC). Then, the Japanese Aerospace Exploration Agency (JAXA) will launch three payloads out of the Tanegashima Space Center in Japan on what aims to be the first successful launch of the H3 rocket. Finally, a Soyuz 2.1a will launch from the Baikonur Cosmodrome in Kazakhstan taking supplies up to the ISS.

SpaceX Falcon 9 | PACE

On Thursday, Feb. 8 at 1:33 AM EST (06:33 UTC), SpaceX launched NASAs PACE Earth-observation satellite on a Falcon 9 out of SLC-40 from CCSFS.

PACE is a long-term Earth-observation satellite that will show constant models of global ocean color, cloud, and aerosol data. This satellite has many different uses all in one package and will benefit humanitys understanding of the Earth by watching for changes and inconsistencies to predict environmental phenomena such as weather, visibility, and air quality.

The booster launching this mission was B1081-4, which propulsively returned to Landing Zone 1 (LZ-1) shortly after launch. The second stage inserted PACE into a 676.5-kilometer Sun-synchronous polar orbit inclined 98 degrees.

SpaceX Falcon 9 | Starlink Group 7-13

Following multiple delays due to unfavorable recovery and cloud conditions, SpaceX is now targeting Feb. 9 at 9:01 PM PST (Feb. 10 at 05:01 UTC) for the launch of Starlink Group 7-13 from SLC-4E at Vandenberg Space Force Base in California. SpaceX has targeted Feb. 6 and Feb. 8 for this launch although both attempts were scrubbed due to excessive weather conditions.

An expected 22 v2 Mini satellites will be lofted to a 53-degree inclination orbit on a southeastern trajectory. The booster B1071 will have launched 14 times and plans to land on the autonomous droneship Of Course I Still Love You downrange in the Pacific Ocean.

The specific booster set to launch the mission is not yet known. Group 7-13 is set to be the 11th SpaceX Falcon 9 launch of the year, and the 25th orbital launch attempt for the year overall.

SpaceX Falcon 9 | Starlink Group 6-39

SpaceX will be launching another stack of Starlink satellites on Feb. 10 at 1:00 AM EST (06:00 UTC) from SLC-40 out of CCSFS in Florida. Starlink Group 6-39 will have a payload of 23 Starlink v2 Mini satellites. These satellites will be heading to an initial low-Earth orbit of 284 by 293 kilometers with a southeastern trajectory inclined 43 degrees. The 23 satellites will be added to the thousands of active Starlink satellites in orbit giving internet to people all over the world.

The booster for this mission is unknown at this time, but it is believed that it will land on one of the two autonomous droneships stationed on the East Coast. This will be the 27th total orbital launch of 2024 with nearly half being Falcon 9 launches.

SpaceX Falcon 9 | Nova-C (IM-1)

Falcon 9s 300th flight and the next mission to the Moon is launching on Feb. 14 at 12:57 AM EST (05:57 UTC). Falcon 9 is set to take Intuitive Machines first Nova-C lunar lander to a trans-lunar injection. Lifting off from historic LC-39A at KSC in Florida, Falcon 9 will launch with an unknown booster and then return to LZ-1 while the second stage does the heavy lifting, taking Nova-C out to the Moon.

Nova-C is the next lunar lander in NASAs Commercial Lunar Payload Services (CLPS) program. CLPS was created to give private companies the resources to build commercial lunar landers to send NASA payloads to the Moon before the crewed Artemis III landing. It will carry five NASA payloads and four private or university payloads with plans to study plume-surface interactions, radio astronomy, and space weather interactions on the lunar surface. The lander will touch down in Malapert A, a crater near the south pole of the Moon.

SpaceX has upgraded LC-39As strongback with new propellant connections to load Nova-C with liquid oxygen and liquid methane propellants while vertical on the launch pad. Recently, SpaceX has performed tests on the new system at the pad before the integrated vehicle is brought out for a wet dress rehearsal in the coming days.

It appears that SpaceX may be testing the TE at 39A with the new connections that should allow @Int_Machines's Nova-C lander to be loaded with propellants while on the pad. The lander uses cryogenic oxygen and methane fluids for its propulsion system.https://t.co/bWDuxt1M5U pic.twitter.com/ELmTDpjPiZ

Alejandro Alcantarilla Romera (Alex) (@Alexphysics13) January 21, 2024

The landing of Nova-C is planned for Feb. 22 with the operation time on the lunar surface being nearly 14 Earth days. Intuitive Machines is following closely after Astrobotics Peregrine Mission One another CLPS lander which failed to land on the Moon last month after a propulsion system malfunction.

If everything goes well with this flight, Intuitive Machines has a second lunar lander lined up to launch in the second quarter of this year to send more NASA, university, and commercial payloads to the lunar surface.

JAXA/MHI H3-22 | VEP 4, CE-SAT-1E & TIRSAT

The second flight of the JAXA and Mitsubishi Heavy Industries (MHI) H3-22 rocket is set for Feb. 15 at 9:22 AM JST (00:22 UTC) from LA-Y2 out of the Tanegashima Space Center in Japan. H3 is classified as a medium-lift launch vehicle and uses cryogenic liquid hydrogen and liquid oxygen in its first and second stages. The core rocket can then optionally be augmented by two or four solid rocket boosters.

This mission will use two boosters along with a short payload fairing, taking three payloads into a Sun-synchronous orbit.

The first flight of H3 experienced a failure of the second engine ignitor causing the test payload to fall short of orbit. While flight two was originally planned to launch the ALOS-4 Earth observation satellite, the vehicle failure caused JAXA to choose to fly the Vehicle Evaluation Payload-4 (VEP-4) mass simulator, although there are also two small satellites onboard for this flight.

CE-SAT-1E is a 70-kilogram Earth observation satellite built by Canon Electronics Inc., and TIRSAT is a five-kilogram 3U CubeSat from Japan Space Systems to test infrared sensors for Earth observation. While there is an inherent risk to flying an unproven rocket, the customers are confident in the new vehicles ability to take their payloads to orbit.

Roscosmos Soyuz 2.1a | Progress MS-26

The next resupply mission to the ISS is launching on a Soyuz 2.1a to low-Earth orbit on Feb. 15 at 9:25 AM AQTT (03:25 UTC) from Site 31/6 at the Baikonur Cosmodrome in Kazakhstan. This mission will take Progress MS-26 to the ISS, carrying food, water, oxygen, fuel, and more to keep the Station and its astronauts healthy.

This will be Soyuz 2.1as 74th overall mission but the first of 2024. Progress MS-26s docking time is unknown, as is the date of its departure from the Station. This will be the 179th Progress mission since the first flight back in 1978.

Weather 40% Favorable for Tuesday PACE Mission Launch PACE Mission - NASA Blogs

SpaceX wants to launch its giant Starship vehicle often over the coming months, as a new photo makes abundantly clear.

In a post on X this afternoon (Feb. 2), SpaceX shared photos of the "megabay" at its Stabase site in South Texas, the center of Starship manufacturing and launch activities.

The building is jam-packed with towering stainless-steel cylinders Super Heavy vehicles, the first stage of SpaceX's Starship megarocket which rise nearly to the roof.

"Super Heavy boosters for the next three flights, with a fourth ready to stack, in the Starbase Megabay," SpaceX wrote in the post.

Related:See stunning photos and video of Starship's 2nd launch

Starship consists of two elements, both of which are designed to be fully and rapidly reusable: Super Heavy and a 165-foot-tall (50 meters) upper-stage spacecraft called Starship.

When fully stacked, Starship stands about 400 feet (122 meters) tall. It's the biggest and most powerful rocket ever built, capable of launching up to 150 tons of payload to low Earth orbit, according to SpaceX's spec sheet.

Starship isn't up and running yet, however; it has launched just twice to date, on test flights in April and November of last year. Both ended in powerful explosions. But Starship made enough progress on the second liftoff acing a full-duration Super Heavy burn and successfully separating its two stages, for example that success seems like a real possibility on flight number three, which may be just around the corner.

Indeed, SpaceX aims to launch the test mission this month, provided it secures a launch license from the U.S. Federal Aviation Administration in time. (The FAA is overseeing an investigation into what happened on the November flight.)

SpaceX thinks that Starship's combination of power and reusability will lead to huge breakthroughs in exploration, allowing humanity to put down stakes on the moon and Mars.

NASA sees promise in the vehicle: It selected Starship to be the first crewed moon lander for its Artemis program, which aims to establish a permanent human presence on and around Earth's nearest neighbor by the end of the 2020s. Starship will put astronauts down on the lunar surface for the first time in 2026, on the Artemis 3 mission, if all goes according to plan.

Tug: Debra C; Support: GO Beyond

SpaceXs Starlink Group 7-13 mission will launch 22 Starlink v2 Mini satellites atop a Falcon 9 rocket; unlike on Starlink Group 7-9, none of these satellites have direct-to-cell capability. The Falcon 9 will lift off from Space Launch Complex 4 East (SLC-4E), at Vandenberg Space Force Base, in California, United States. Starlink Group 7-13 will mark the 137th operational Starlink mission, boosting the total number of Starlink satellites launched to 5,828, of which ~5,438 will still be in orbit around the Earth once launched.

Starlink is SpaceXs internet communication satellite constellation. The low-Earth orbit constellation delivers fast, low-latency internet service to locations where ground-based internet is unreliable, unavailable, or expensive.The first phase of the constellation consists of five orbital shells.

Starlink is currently available in certain regions, allowing anyone in approved regions to order or preorder. After 28 launches SpaceX achieved near-global coverage, but version one of the constellation will not be complete until all five shells are filled. Once Starlink generations 1 and 2 are complete, the venture is expected to profit $30-50 billion annually. This profit will largely finance SpaceXs ambitious Starship program, as well as Mars Base Alpha.

Each Starlink v1.5 satellite has a compact design and a mass of 307 kg. SpaceX developed a flat-panel design, allowing them to fit as many satellites as possible into the Falcon 9s 5.2-meter wide payload fairing. Due to this flat design, SpaceX is able to fit up to 60 Starlink satellites and the payload dispenser into the second stage, while still being able to recover the first stage. This is near the recoverable payload capacity of the Falcon 9 to LEO, around 18 tons.

As small as each Starlink satellite is, each one is packed with high-tech communication and cost-saving technology. Each Starlink satellite is equipped with four phased array antennas, for high bandwidth and low-latency communication, and two parabolic antennas. The satellites also include a star tracker, which provides the satellite with attitude data, ensuring precision in broadband communication.

Each Starlink v1.5 satellite is also equipped with an inter-satellite laser communication system. This allows each satellite to communicate directly with other satellites, not having to go through ground stations. This reduces the number of ground stations needed, allowing coverage of the entire Earths surface, including the poles.

The Starlink satellites are also equipped with an autonomous collision avoidance system, which utilizes the US Department of Defense (DOD) debris tracking database to autonomously avoid collisions with other spacecraft and space junk.

To decrease costs, each satellite has a single solar panel, which simplifies the manufacturing process. To further cut costs, Starlinks propulsion system, an ion thruster, uses krypton as fuel, instead of xenon. While the specific impulse (ISP) of krypton is significantly lower than xenons, it is far cheaper, which further decreases the satellites manufacturing cost.

Each Starlink satellite is equipped with the first Hall-effect krypton-powered ion thruster. This thruster is used for both ensuring the correct orbital position, as well as for orbit raising and orbit lowering. At the end of the satellites life, this thruster is used to deorbit the satellite.

SpaceXs Starlink v2 satellites are larger, more powerful satellites meant to be launched on SpaceXs Starship launch vehicle. While little is known about these satellites thus far, it is known that they mass roughly 1,200 kg and feature a twin-solar array design, to increase power delivered to the satellite. On top of this, according to SpaceX CEO and CTO Elon Musk, the satellites will have an order of magnitude more bandwidth, higher speeds, and be roughly 10x better in every way.

Starting on Starlink Group 7-9, some Starlink v2 satellites will act as cell towers, providing worldwide cell phone coverage to T-Mobile customers. Musk has stated that each of these satellites will have roughly 2-4 Mb/s of bandwidth per cell phone zone, which will allow for tens of thousands of SMS text messages per second or many users placing phone calls. While this technology is primarily meant for contacting emergency services worldwide (similar to Apples connect to satellite feature on the iPhone 14 and 15 series), it will also be able to be used for sending non-emergency-related messages.

Due to delays in the Starship launch vehicle, SpaceX is launching Starlink v2 Mini satellites that will launch on the Falcon 9 rocket. These satellites have a more powerful phased array antenna and utilize the E-band for backhaul. This allows each satellite to provide 4x more capacity than Starlink v1.0 and v1.5.

The Starlink v2 Mini satellites are equipped with a new argon Hall thruster for on-orbit maneuvering. These generate 2.4 times as much thrust as the thrusters on v1.5 satellites and have 1.5 times the specific impulse. Starlink v2 Mini satellites are the first satellites to use an argon thruster on-orbit.

A satellite constellation is a group of satellites that work in conjunction for a common purpose. SpaceXs Starlink constellation consists of two generations: the first (which is largely complete) is filled with Starlink v1/1.5 satellites and the second is to be filled with Starlink v2 and v2 Mini satellites.

Starlink Generation One consists of five orbital shells and has a total of 4,408 satellite slots. These satellites will entirely be launched on Falcon 9, and it is expected for these launches to finish in 2023.

Generation Two consists of 29,988 satellitesthis is roughly 20 times more satellites than were ever launched before the start of Starlink in 2019. These satellites will primarily be launched by Starship; however, as previously mentioned, Falcon 9 will launch some of these satellites while Starship is not operational.

Due to the vast number of Starlink satellites, many astronomers are concerned about their effect on the night sky. However, SpaceX is working with the astronomy community and implementing changes to the satellites to make them harder to see from the ground and less obtrusive to the night sky. SpaceX has changed how the satellites raise their orbits and, starting on Starlink v1.0 L9, added a sunshade to reduce light reflectivity. These changes have already significantly decreased the effect of Starlink on the night sky.

The first orbital shell of Starlink satellites consists of 1,584 satellites in a 53.0 550 km low-Earth orbit. Shell 1 consists of 72 orbital planes, with 22 satellites in each plane. This shell is currently near complete, with occasional satellites being replaced. The first shell provides coverage between roughly 52 and -52 latitude (~80% of the Earths surface), and will not feature laser links until replaced.

Starlinks second shell will host 720 satellites in a 70 570 km orbit. These satellites will significantly increase the coverage area, which will make the Starlink constellation cover around 94% of the globe. SpaceX will put 20 satellites in each of the 36 planes in the third shell. This shell is currently being filled, along with Shell 4.

Shell 3 will consist of 348 satellites in a 97.6 560 km orbit. SpaceX deployed 10 laser link test satellites into this orbit on its Transporter-1 mission to test satellites in a polar orbit. SpaceX launched an additional three satellites to this shell on the Transporter-2 mission. On April 6, 2021, Gwynne Shotwell said that SpaceX will conduct regular polar Starlink launches in the summer, but this shell is now the lowest priority and is expected to be the last filled. All satellites that will be deployed into this orbit will have inter-satellite laser link communication. Shell 3 will have six orbital planes with 58 satellites in each plane.

The fourth shell will consist of 1,584 satellites in a 540 km 53.2 LEO. This updated orbital configuration will slightly increase coverage area and will drastically increase the bandwidth of the constellation. This shell will also consist of 72 orbital planes with 22 satellites in each plane. This shell is currently being filled alongside Shell 2.

The final shell of Phase 1 of Starlink will host 172 satellites in another 97.6 560 km low-Earth polar orbit. Shell 5 will also consist purely of satellites with laser communication links; however, unlike Shell 3, it will consist of four orbital planes with 43 satellites in each plane.

However, it is unclear if this shell will still be filled; previous group 5 launches have gone to a 43 orbit.

The Starlink gen 2 constellation consists of nine orbital shells. It is currently unclear how these shells will be named.

The Falcon 9 Block 5 is SpaceXs partially reusable two-stage medium-lift launch vehicle. The vehicle consists of a reusable first stage, an expendable second stage, and, when in payload configuration, a pair of reusable fairing halves.

The Falcon 9 first stage contains nine Merlin 1D+ sea-level engines. Each engine uses an open gas generator cycle and runs on RP-1 and liquid oxygen (LOx). Each engine produces 845 kN of thrust at sea level, with a specific impulse (ISP) of 285 seconds, and 934 kN in a vacuum with an ISP of 313 seconds. Due to the powerful nature of the engine, and the large amount of them, the Falcon 9 first stage is able to lose an engine right off the pad, or up to two later in the flight, and be able to successfully place the payload into orbit.

The Merlin engines are ignited by triethylaluminum and triethylborane (TEA-TEB), which instantly burst into flames when mixed in the presence of oxygen. During static fire and launch the TEA-TEB is provided by the ground service equipment. However, as the Falcon 9 first stage is able to propulsively land, three of the Merlin engines (E1, E5, and E9) contain TEA-TEB canisters to relight for the boost back, reentry, and landing burns.

The Falcon 9 second stage is the only expendable part of the Falcon 9. It contains a singular MVacD engine that produces 992 kN of thrust and an ISP of 348 seconds. The second stage is capable of doing several burns, allowing the Falcon 9 to put payloads in several different orbits.

SpaceX is currently flying two different versions of the MVacD engines nozzle. The standard nozzle design is used on high-performance missions. The other nozzle is a significantly shorter version of the standard, decreasing both performance and material usage; with this nozzle, the MVacD engine produces 10% less thrust in space. This nozzle is only used on lower-performance missions, as it decreases the amount of material needed by 75%. This means that SpaceX can launch over three times as many missions with the same amount of Niobium as with the longer design.

For missions with many burns and/or long coasts between burns, the second stage is able to be equipped with a mission extension package. When the second stage has this package it has a grey strip, which helps keep the RP-1 warm, an increased number of composite-overwrapped pressure vessels (COPVs) for pressurization control, and additional TEA-TEB.

The booster supporting the Starlink Group 7-13 mission is B1071-14; as the name implies, the booster has supported 13 previous missions. Following the landing, its designation will change to B1071-15.

Following stage separation, the Falcon 9 will conduct two burns. These burns aim to softly touch down the booster on SpaceXs autonomous spaceport drone ship Of Course I Still Love You.

The Falcon 9s fairing consists of two dissimilar reusable halves. The first half (the half that faces away from the transport erector) is called the active half, and houses the pneumatics for the separation system. The other fairing half is called the passive half. As the name implies, this half plays a purely passive role in the fairing separation process, as it relies on the pneumatics from the active half.

Both fairing halves are equipped with cold gas thrusters and a parafoil which are used to softly touch down the fairing half in the ocean. SpaceX used to attempt to catch the fairing halves, however, at the end of 2020 this program was canceled due to safety risks and a low success rate. On Starlink Group 7-13, SpaceX will attempt to recover the fairing halves from the water with its recovery vessel GO Beyond.

In 2021, SpaceX started flying a new version of the Falcon 9 fairing. The new upgraded version has vents only at the top of each fairing half, by the gap between the halves, whereas the old version had vents placed spread equidistantly around the base of the fairing. Moving the vents decreases the chance of water getting into the fairing, making the chance of a successful scoop significantly higher.

"Flying SpaceX was our pleasure," Ax-3 commander Michael Lopez-Alegria, a former NASA astronaut, replied as the Freedom capsule bobbed in the Atlantic. "All four crewmembers are feeling well."

Ax-3 launched atop a SpaceX Falcon 9 rocket on Jan. 18 and arrived at the International Space Station (ISS) in the early morning hours of Jan. 20.

The mission consists of four crewmembers: Commander Michael Lpez-Alegra, a formerNASAspaceflyer who's now Axiom Space's chief astronaut; pilot Walter Villadei, a colonel in the Italian Air Force; mission specialist Alper Gezeravc, the first citizen of Turkey ever to reach space; and mission specialist Marcus Wandt, an European Space Agency reserve astronaut. It is SpaceX's first private all-European mission.

The quartet performed more than 56 scientific experiments during their time aboard the ISS, including work in physics and space medicine. They spoke with a wide variety of dignitaries, students and at the European Space Conference during their stay, including a call to actor Melissa Navia, who portrays Lt. Ortegas on "Star Trek: Strange New World."

"Data collected on ground before and after the mission as well as in flight will impact understanding of human physiology on Earth and on orbit, as well as advance scientific understanding, harness opportunities for industrial advancements, and develop technologies for humanity's progress," Axiom Space wrote in a mission description.

Freedom undocked from the ISS on Wednesday (Feb. 7) at 9:20 a.m. EST (1420 GMT), ending Ax-3's stay aboard the orbiting lab. That stay was expected to end on Saturday (Feb. 3), but bad weather in the splashdown zone pushed it back four days.

"It's been an incredible, busy and fun-filled two weeks up here," Lpez-Alegra said during a livestreamed departure ceremony aboard the ISS on Friday (Feb. 2). "I am very proud of my Ax-3 crewmates, who helped their agencies achieve all of their science objectives, technology demonstrations, as well as the outreach events."

"It's been a real pleasure and honor to have you onboard the International Space Station," ESA astronaut Andreas Mogensen, who commands the station's current Expedition 70 mission, said during the ceremony. "You guys have been great crewmates."

Ax-3 is the sixth spaceflight for Lpez-Alegra. Among his previous missions was Ax-1, which flew to the ISS in April 2022; he is the only person ever to have ridden Dragon to orbit twice. The Ax-2 mission in 2023 was commanded by former NASA astronaut Peggy Whitson.

The other three Ax-3 astronauts had never been to orbit before, though Villadei did reach suborbital space with Virgin Galactic in June 2023.

Ax-3 mission concludes as SpaceX Dragon heads home with astronauts and science aboard, aiming for a Florida coast return.

The SpaceX Dragon spacecraft undocked from the space-facing port of the International Space Stations Harmony module at 9:20 a.m. EST over the Pacific Ocean, west of Ecuador, to complete the third all-private astronaut mission to the orbiting laboratory, Axiom Mission 3 (Ax-3).

Dragon is slowly maneuvering away from the orbital laboratory into an orbital track that will return the astronaut crew and its cargo safely to Earth, targeting a splashdown off the coast of Daytona, Florida, at approximately 8:30 a.m. EST Friday, February 9.

Ax-3 astronauts Michael Lpez-Alegra, Walter Villadei, Marcus Wandt, and Alper Gezeravci will complete 18 days aboard the orbiting laboratory at the conclusion of their mission. The SpaceX Dragon will return to Earth with more than 550 pounds of science and supplies, including NASA experiments and hardware.

Joint operations with the Axiom and SpaceX mission teams end and NASA coverage of the mission concludes when the spacecraft exits the area of the space station, approximately 30 minutes after undocking.

Axiom Space leads independent mission operations for Ax-3 and will resume coverage of Dragons re-entry and splashdown.
