SpaceX is already preparing for operational astronaut missions
While the world’s attention is focused on the return of orbital human spaceflight from US soil after a nearly decade long absence with the upcoming May 27th Crew Dragon Demo-2 mission, SpaceX is simultaneously preparing for the first Crew Dragon operational mission certified by NASA, dubbed Crew-1, slated to occur later this year.
On Friday, April 24th, SpaceX treated its Twitter followers to some rare imagery of static fire testing completed at the company’s development facility in McGregor, Texas. The company spotlighted a fresh-from-the-factory Falcon 9 booster and Falcon 9 second stage Merlin Vaccum (MVac) engine intended for the Crew-1 mission. Crew-1, the follow-up mission to May’s Demo-2 mission and SpaceX’s first operational human spaceflight mission for NASA, will propel a crew of three NASA astronauts and one JAXA astronaut in a Crew Dragon capsule to the International Space Station.
SpaceX also provided its followers with a view of the pristine second stage MVac engine of the Crew-1 mission before it was sent to Texas for testing. The one-hundredth production MVac engine is seen inside of SpaceX’s manufacturing facility located in Hawthorne, CA before being prepared for shipment. The second stage MVac engine is the only piece of Falcon 9 hardware that SpaceX does not actively recover and reuse, unlike the first-stage booster and protective payload fairing nosecone.
Part of the process
A static fire test is a typical occurrence before shipping the booster and second stage to Florida for payload integration and launch. The static fire process involves holding down the booster and igniting the engines to run for a full-duration firing. A similar test is also performed on with the second stage MVac engine. These test-fires are performed at the Mcgregor facility to proof the vehicle and check for any inconsistencies or off-nominal test readings that may occur before shipping to the vehicle to the launch site. Following the test-fire, the entire vehicle is inspected, cleaned, and prepared for shipment.
A test-fire in Mcgregor is not the last time the engines will be put through the paces before launch. Typically a week or so before the scheduled launch date, the Falcon 9 booster is transported to the launch pad. There, the booster is fully fueled with propellant while securely held to the launch mount. All nine Merlin-1D engines are once again ignited briefly (anywhere between 6 – 12 seconds) to test the propellant load process and collect engine-firing measurements such as temperature and pressure.
Certification before operation
Although the Crew-1 mission is tentatively on the books for later this year, SpaceX and the Crew Dragon capsule have yet to achieve NASA certification to begin operational missions to and from the International Space Station. The second orbital demonstration flight of the Crew Dragon capsule (Demo-2) will serve as the final end-to-end test of SpaceX’s crew transportation system.
However, SpaceX still faces a few obstacles before achieving a full go-ahead by NASA for the launch of Demo-2. As reported by SpaceNews.com NASA’s Aerospace Safety Advisory Panel (ASAP) met via teleconference on Thursday, April 23rd for a routine quarterly briefing. In that meeting, it was briefly discussed that there are still a few “technical items” that remain to be cleared by NASA before the launch of the Demo-2 mission.
Although not specified in the briefing – and likely to be followed up on during “part 2” of the ASAP meeting to be held in early May – those items likely refer to wrapping up the joint investigation of a recent in-flight engine failure of a Falcon 9 Merlin-1D engine and one more qualifying drop-test of the Crew Dragon Mark 3 parachutes. SpaceX, however, shows no plans letting formalities stop the preparation to support future astronaut missions.

SpaceX is rolling out a new feature to Starlink that could be a lifesaver
Starlink now has a new Standby Mode that will enable low-speed internet access in the event of an outage.

SpaceX is rolling out a new feature to Starlink that could be a lifesaver in some instances, but more of a luxury for others.
Starlink is the satellite internet service that Elon Musk’s company SpaceX launched several years ago. It has been adopted by many people at their homes, many airlines on their planes, and many maritime companies on their ships.
It has been a great way for customers to relieve themselves of the contracts and hidden fees of traditional internet service providers.
Now, Starlink is rolling out a new service feature on its units called “Standby Mode,” which is part of Pause Mode. The company notified customers of the change in an email:
“We’re reaching out to you to let you know the Pause feature on your plan has been updated. Pause now includes Standby Mode, which comes with unlimited low-speed data for $5.00 per month, perfect for backup connectivity and emergency use. These updates will take effect in 30 days. All of your other plan features remain the same. You are able to cancel your service at any time for no charge.”
SpaceX did not define how fast these “low speeds” will be. However, there are people who have tested the Standby Mode, and they reported speeds of about 500 kilobytes per second.
The mode is ideal for people who might deal with internet or power outages, but still need to have some sort of internet access.
It could also be used as a backup for people who want to stay with their ISP, but would like to have some sort of alternative in case of an outage for any reason.

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.
🚨 Just wanted you to know, Starship 10’s projected test flight date, according to Grok, is August 4.
Starship’s ninth test flight took place on May 27.
August 4 is 69 days after May 27.
Do with that what you will. 🚀 https://t.co/IISpT08rIy

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:
Launching again in ~3 weeks
— Elon Musk (@elonmusk) July 14, 2025
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.

SpaceX Ax-4 Mission prepares for ISS with new launch date
SpaceX, Axiom Space, and NASA set new launch date for the Ax-4 mission after addressing ISS & rocket concerns.

SpaceX is preparing for a new launch date for the Ax-4 mission to the International Space Station (ISS).
SpaceX, Axiom Space, and NASA addressed recent technical challenges and announced a new launch date of no earlier than Thursday, June 19, for the Ax-4 mission. The delay from June 12 allowed teams to assess repairs to small leaks in the ISS’s Zvezda service module.
NASA and Roscosmos have been monitoring leaks in the Zvezda module’s aft (back) segment for years. However, stable pressure could also result from air flowing across the hatch seal from the central station. As NASA and its partners adapt launch schedules to ensure station safety, adjustments are routine.
“Following the most recent repair, pressure in the transfer tunnel has been stable,” a source noted, suggesting the leaks may be sealed.
“By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda,” the source added.
SpaceX has also resolved a liquid oxygen leak found during post-static fire inspections of the Falcon 9 rocket, completing a wet dress rehearsal to confirm readiness. The Ax-4 mission is Axiom Space’s fourth private astronaut trip to the ISS. It will launch from NASA’s Kennedy Space Center in Florida on a Falcon 9 rocket with a new Crew Dragon capsule.
“This is the first flight for this Dragon capsule, and it’s carrying an international crew—a perfect debut. We’ve upgraded storage, propulsion components, and the seat lash design for improved reliability and reuse,” said William Gerstenmaier, SpaceX’s vice president of build and flight reliability.
The Ax-4 mission crew is led by Peggy Whitson, Axiom Space’s director of human spaceflight and former NASA astronaut. The Ax-4 crew includes ISRO astronaut Shubhanshu Shukla as pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary. The international team underscores Axiom’s commitment to global collaboration.
The Ax-4 mission will advance scientific research during its ISS stay, supporting Axiom’s goal of building a commercial space station. As teams finalize preparations, the mission’s updated launch date and technical resolutions position it to strengthen private space exploration’s role in advancing space-based innovation.
