SpaceX ships Mars engine to Texas for testing
The foundation of any space program is the rocket engines that lift people and payloads off the ground and send them on their way to distant destinations, whether the target is the International Space Station, the moon, or Mars. To date, SpaceX has relied upon its Merlin rocket engine to power its space missions.
But Elon Musk has larger goals for SpaceX than putting satellites into orbit or ferrying astronauts to the ISS. His ultimate plan is to establish a human colony on Mars. That will require more powerful rockets than the Merlin engines used for today’s space missions.
Musk says the next generation Raptor engine is three times more powerful than the Merlin and will generate up to 500,000 lbs of thrust. A cluster of nine Raptor engines will be used to lift the Mars Colonial Transporter on its way to the Red Planet.
This week, SpaceX president Gail Shotwell told the Small Satellite Conference held in Logan, Utah that a Raptor engine has been shipped to the company’s test site in MacGregor, Texas.
Aerospace engineers say it usually takes five to seven years to develop a new rocket engine. Full scale engine testing typically takes place toward the end of the development process. If testing of the Raptor is about to begin, that suggests SpaceX is on target to send a manned Dragon spacecraft to Mars as early as 2020. SpaceX has already successfully demonstrated the supersonic retro-rocket technology it will need to land the Dragon capsule on Mars.
Musk says he will unveil more details about how SpaceX will colonize Mars at this year’s International Astronautical Conference in Guadalajara, Mexico scheduled for September 26 this year. He is often criticized for setting time tables that are overly optimistic, but if testing of the Raptor engine is about to get underway, that would indicate the Mars colonization program is right on time.
Editor’s note: Corrected a passage that originally suggested that an “unmanned” Dragon would take flight in 2020 which in fact should be “manned”.

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’s Crew-11 mission targets July 31 launch amid tight ISS schedule
The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida.

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 launches Ax-4 mission to the ISS with international crew
The SpaceX Falcon 9 launched Axiom’s Ax-4 mission to ISS. Ax-4 crew will conduct 60+ science experiments during a 14-day stay on the ISS.

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.
