Watch SpaceX fire Starship’s Raptor engines ahead of 4th test flight

SpaceX performed a full-duration static fire of all six Raptor engines on its Starship spacecraft on Monday, and shared a video of the dramatic test on social media.

The static fire, which involved tethering the vehicle to the ground before igniting the engines, took place ahead of the fourth test flight of the entire rocket. The rocket consists of the first-stage Super Heavy — the most powerful booster in the world — and the upper-stage Starship spacecraft. Collectively and somewhat confusingly, the entire vehicle is known as the Starship.

The Starship spacecraft deploys its rocket engines once separated from the Super Heavy booster. One of the engines’ most important roles is to guide and slow the spacecraft as it descends for an upright landing, whether on Earth or some other celestial body. The Starship achieved such a landing during testing in a solo suborbital flight in 2021.

As with the first two test missions, which took place in April and November last year, the Federal Aviation Administration (FAA) is overseeing an investigation into the third test flight that took place earlier this month. Once that is complete, the FAA will likely hand SpaceX a permit for the fourth flight, which SpaceX believes could get airborne as early as May.

The Starship has performed better with each flight, with the third test achieving a slew of firsts that included getting the Starship spacecraft to orbit. SpaceX engineers have been taking data collected from each test mission and using it to improve the flight systems, and therefore, much is expected from the fourth flight.

Once fully tested, the 120-meter-tall Starship rocket is expected to carry crew and cargo to the moon and possibly even to Mars. But a lot of development work still has to be completed before the rocket is deemed safe enough for such ambitious missions.

Cool time-lapse shows SpaceX Crew-10 arriving at space station
SpaceX's Crew-10 arriving at the ISS in March 2025.

Space station astronaut Don Pettit has shared a cool time-lapse of SpaceX’s Crew-10 Crew Dragon spacecraft arriving at the orbital facility on Sunday.

The footage, which runs more quickly than the actual speed, shows the capsule approaching the docking port on the International Space Station (ISS), which orbits at around 250 miles above Earth. Pettit posted a short and long version of the spacecraft's autonomous approach:

SpaceX will launch Tesla’s humanoid Optimus robot to Mars next year
Optimus Gen 2 humanoid robot by Tesla.

The year 2025 is going to be pivotal for Tesla’s humanoid robot plans, if the words of CEO Elon Musk are to be believed. But next year could mark an astronomical milestone for the company’s Optimus robot, in quite the literal sense.
Taking to X, Musk mentioned in a post that SpaceX will put an Optimus robot on Mars atop its flagship Starship rocket by the end of 2026. Just over a week ago, the Starship broke apart following a launch test, the second such failure this year.
“Starship departs for Mars at the end of next year, carrying Optimus,” Musk wrote in a post on X. “If those landings go well, then human landings may start as soon as 2029, although 2031 is more likely.”

This won’t be the first time Musk is making such a claim. Back in November last year, Musk mentioned that SpaceX was capable of sending “several uncrewed Starships” to the red planet within a couple of years and that the payload would include Optimus robots.
Tesla introduced a refined version of the Optimus robot at a glitzy event late in 2024. At the event, Musk told the crowd that Optimus was “the biggest product ever of any kind.” It was later reported that the robots were remotely operated by humans at the event.
Later, during the company’s Q4 2024 earnings calls, Musk shed more light on production plans, adding that the product has a revenue potential higher than $10 trillion. He also mentioned plans to manufacture thousands of humanoid robots in 2025.

Watch SpaceX launch a relief crew for ‘stuck’ Starliner astronauts
At 7:03 p.m. EDT, the SpaceX Falcon 9 rocket and Dragon spacecraft, carrying NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov, launched from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Friday, March 14, 2025..

Four astronauts are on their way to the International Space Station (ISS). After several delays, the members of Crew-10 lifted off in a SpaceX Dragon spacecraft using a Falcon 9 rocket from NASA's Kennedy Space Center in Florida at 7:03 p.m. ET on Saturday night. The crew includes NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov.

“Congratulations to our NASA and SpaceX teams on the 10th crew rotation mission under our commercial crew partnership. This milestone demonstrates NASA’s continued commitment to advancing American leadership in space and driving growth in our national space economy,” said NASA acting Administrator Janet Petro. “Through these missions, we are laying the foundation for future exploration, from low Earth orbit to the Moon and Mars. Our international crew will contribute to innovative science research and technology development, delivering benefits to all humanity.”
