Although the chances of additional delays are high, the orbital launch debut of SpaceX’s Crew Dragon spacecraft remains stoically targeted for 2:47 am EDT (07:47 UTC) on March 2nd, less than ten days from today.

Known as DM-1, the unproven SpaceX vehicle’s autonomous demonstration mission is a critical milestone along the road to assured US access to the International Space Station (ISS), without which NASA will be forced to continue procuring seats on Russian Soyuz missions with aggressively inflated price tags. If everything goes exactly as planned, a successful DM-1 could translate into the company’s first crewed launch as early as July 2019.

Following a nominal mission plan, the first spaceworthy Crew Dragon will dock with the ISS a little over 24 hours after launch (March 3rd) with around 180 kg (400 lb) of cargo for the station’s six-astronaut crew. Five days later (March 8th), Crew Dragon will depart from the ISS, detach its expendable trunk, and reenter Earth’s atmosphere for a soft landing in the Atlantic Ocean. Throughout these operations, ISS astronauts, NASA technicians and operators, and a range of SpaceX employees will conduct extensive observations and tests of the new spacecraft’s performance during all mission phases, ranging from on-orbit docking (a new technology for SpaceX) to Atlantic Ocean recovery operations.

Once the capsule has been extricated from the ocean, SpaceX’s spacecraft refurbishment technicians will be faced with an extraordinary challenge, upon which the date of Crew Dragon’s first crewed launch will directly hinge. Assuming splashdown ops are nominal and Dragon is returned safely to Florida, it’s safe to assume that SpaceX will transport the spacecraft to its Hawthorne factory, at which point its engineers and technicians will have roughly two months to prepare it for another launch. Known as an in-flight abort (IFA) test, SpaceX specifically opted to perform the spacecraft safety check despite the fact that NASA did not explicitly require its commercial providers (Boeing and SpaceX) to do so. SpaceX completed Crew Dragon’s pad abort test – required by NASA – almost four years ago, while Boeing will not perform an in-flight abort before launching astronauts and has its pad abort scheduled no earlier than (NET) May 2019.

 

SpaceX’s IFA test is designed to verify that Crew Dragon is capable of safely extricating its astronaut passengers from a failing rocket at the point of peak aerodynamic (and thus mechanical) stress during launch, known as Max Q. Combined with a pad abort demonstration, where the above situation is replicated but with the rocket and spacecraft motionless on the launch pad, the engineering assumption is that successful aborts at both standstill and Max Q verify that a given spacecraft has proven that it can essentially abort and carry astronauts to safety at any point during launch.

“The launch scenario where an abort is initiated during the ascent trajectory at the maximum dynamic pressure (known as max Q) is a design driver for the launch abort system. It dictates the highest thrust and minimum relative acceleration required between Falcon 9 and the aborting Dragon … Dragon would separate from Falcon 9 at the interface between the trunk and the second stage… Under these conditions, the Falcon 9 vehicle would become uncontrollable and would break apart.” – SpaceX FAA permit, 2018

Aside from a boilerplate Merlin Vacuum engine on the second stage, SpaceX’s IFA test is set to fly on real Falcon 9 hardware that will almost certainly be consigned to total destruction at the point of abort, around 90 seconds after launch. SpaceX’s decision to expend an entirely flightworthy Falcon 9 Block 5 rocket – featuring a booster capable of supporting anywhere from 5-100 lifetime missions – is a tangible demonstration of the company’s commitment to crew safety above all else, although NASA will either partially or fully compensate SpaceX for the milestone. Set to occur no earlier than June 2019, the IFA schedule is explicitly constrained by the successful launch and recovery of Crew Dragon after DM-1 – any delays to that mission will likely translate into IFA delays, which will translate into delays for the first crewed mission (DM-2).

SpaceX’s Cargo Dragon engineers and technicians have a solid amount of experience refurbishing the spacecraft for cargo missions to the ISS, although the average turnaround for flight-proven capsules currently stands around 18-24 months, not exactly on the heels of the 2-3 months currently alotted for the first Crew Dragon. Thanks to the fact that the IFA Crew Dragon does not need to be refurbished to the standards of orbital flight for its second launch, it’s at least conceivable that that aspirational schedule is within reach. SpaceX’s first crewed demonstration mission (DM-2) could occur as early as one month after a successful IFA (July 2019), pending the completion of joint NASA-SpaceX readiness reviews.

Known as flight readiness reviews (FRRs), those joint reviews are no less significant for DM-1, even if they likely are underwhelmingly marked by a copious amount of slideshow presentations and sitting around tables in meeting rooms. The purpose of the reviews (at least nominally) is to essentially have SpaceX attempt to convince NASA (as empirically as possible) that they are ready to launch Crew Dragon. According to NASA, that review will end NET 6pm EDT (23:00 UTC) on February 22nd, followed one hour later by an official press conference featuring NASA and SpaceX officials.

Elon Musk reveals SpaceX’s target for Starship’s 10th launch

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

NASA and SpaceX are targeting July 31 for the launch of Crew-11, the next crewed mission to the International Space Station (ISS). The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida, using the Crew Dragon Endeavour and a Falcon 9 booster.

Crew Dragon Endeavour returns

Crew-11 will be the sixth flight for Endeavour, making it SpaceX’s most experienced crew vehicle to date. According to SpaceX’s director of Dragon mission management, Sarah Walker, Endeavour has already carried 18 astronauts representing eight countries since its first mission with NASA’s Bob Behnken and Doug Hurley in 2020, as noted in an MSN report.

“This Dragon spacecraft has successfully flown 18 crew members representing eight countries to space already, starting with (NASA astronauts) Bob (Behnken) and Doug (Hurley) in 2020, when it returned human spaceflight capabilities to the United States for the first time since the shuttle retired in July of 2011,” Walker said.

For this mission, Endeavour will debut SpaceX’s upgraded drogue 3.1 parachutes, designed to further enhance reentry safety. The parachutes are part of SpaceX’s ongoing improvements to its human-rated spacecraft, and Crew-11 will serve as their first operational test.

The Falcon 9 booster supporting this launch is core B1094, which has launched in two previous Starlink missions, as well as the private Ax-4 mission on June 25, as noted in a Space.com report.

The four-members of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, as well as Japan’s Kimiya Yui and Russia’s Oleg Platonov.

Tight launch timing

Crew-11 is slated to arrive at the ISS just as NASA coordinates a sequence of missions, including the departure of Crew-10 and the arrival of SpaceX’s CRS-33 mission. NASA’s Bill Spetch emphasized the need for careful planning amid limited launch resources, noting the importance of maintaining station altitude and resupply cadence.

“Providing multiple methods for us to maintain the station altitude is critically important as we continue to operate and get the most use out of our limited launch resources that we do have. We’re really looking forward to demonstrating that capability with (CRS-33) showing up after we get through the Crew-11 and Crew-10 handover,” Spetch stated.

SpaceX launched the Falcon 9 rocket kickstarting Axiom Space’s Ax-4 mission to the International Space Station (ISS). Axiom’s Ax-4 mission is led by a historic international crew and lifted off from Kennedy Space Center’s Launch Complex 39A at 2:31 a.m. ET on June 25, 2025.

The Ax-4 crew is set to dock with the ISS around 7 a.m. ET on Thursday, June 26, 2025. Axiom Space, a Houston-based commercial space company, coordinated the mission with SpaceX for transportation and NASA for ISS access, with support from the European Space Agency and the astronauts’ governments.

The Ax-4 mission marks a milestone in global space collaboration. The Ax-4 crew, commanded by U.S. astronaut Peggy Whitson, includes Shubhanshu Shukla from India as the pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary.

“The trip marks the return to human spaceflight for those countries — their first government-sponsored flights in more than 40 years,” Axiom noted.

Shukla’s participation aligns with India’s Gaganyaan program planned for 2027. He is the first Indian astronaut to visit the ISS since Rakesh Sharma in 1984.

Axiom’s Ax-4 mission marks SpaceX’s 18th human spaceflight. The mission employs a Crew Dragon capsule atop a Falcon 9 rocket, designed with a launch escape system and “two-fault tolerant” for enhanced safety. The Axiom mission faced a few delays due to weather, a Falcon 9 leak, and an ISS Zvezda module leak investigation by NASA and Roscosmos before the recent successful launch.

As the crew prepares to execute its scientific objectives, SpaceX’s Ax-4 mission paves the way for a new era of inclusive space research, inspiring future generations and solidifying collaborative ties in the cosmos. During the Ax-4 crew’s 14-day stay in the ISS, the astronauts will conduct nearly 60 experiments.

“We’ll be conducting research that spans biology, material, and physical sciences as well as technology demonstrations,” said Whitson. “We’ll also be engaging with students around the world, sharing our experience and inspiring the next generation of explorers.”

SpaceX’s Ax-4 mission highlights Axiom’s role in advancing commercial spaceflight and fostering international partnerships. The mission strengthens global space exploration efforts by enabling historic spaceflight returns for India, Poland, and Hungary.
