SpaceX successfully recovers Starship’s first stage, a step towards reuse

Bet successful. SpaceX managed, on Sunday October 13, during a spectacular maneuver, to catch up with the first stage of its Starship megarocket during a test flight. A first which could represent a decisive step towards the reuse of this heavy launcher.

“Mechazilla has grabbed the Super Heavy booster!” »the company enthused on its X account after a flight of around nine minutes, in reference to the nickname of its launch tower.

The two stages of the rocket – the largest and most powerful in the world – must, at the end of its development, be recovered and reused after each flight. A strategy aimed at being able to launch more machines more quickly, and for much less money.

Billionaire Elon Musk’s company aims to use Starship to colonize Mars. The development of the spacecraft is also closely monitored by NASA, which is counting on it to bring its astronauts back to the surface of the Moon.

Takeoff for this fifth Starship test flight took place at 7:25 a.m. local time (2:25 p.m. Paris time) from the company’s Starbase space base in the far south of Texas, United States.

The rocket consists of the Super Heavy first stage and, above it, the Starship, which by extension gives its name to the entire launcher. Super Heavy alone is some 70 meters tall (the complete rocket is 120).

During each flight, Super Heavy detaches from the ship after propelling it using its 33 powerful engines. Until now, it was going to end its journey in the sea, but SpaceX this time managed to get it back on its launch pad, from the first attempt of this delicate maneuver, around nine minutes after takeoff.

Before the Super Heavy stage could touch the ground, mechanical arms installed on the launch tower, nicknamed “the chopsticks”closed on him and immobilized him, we could see on the SpaceX video feed.

“SpaceX engineers spent years preparing for the capture attempt”the company wrote ahead of the launch. “Tens of thousands of hours” were devoted by the technicians “putting in place the infrastructure necessary to maximize our chances of success”she added.

Risky maneuver

For its part, the Starship will continue its flight until landing in the Indian Ocean. It had for the first time successfully landed gently in this ocean during the previous test flight, four months ago.

Images broadcast live by cameras on the ship then showed a layer of orange plasma when it returned from space, due to friction with the atmosphere. Pieces had broken off under the pressure. Since then, SpaceX has said it has carried out “a complete overhaul of the heat shield” of the ship, by laying tiles “new generation”.

Controversies

The development of Starship is being carried out vigorously by SpaceX, launching prototypes without cargo, in order to quickly correct the problems encountered in real flight situations.

In recent weeks, the company has openly complained about the slowness of the American aviation regulator (Federal Aviation Administration, FAA), responsible for flight authorizations. “It takes more time to complete the paperwork required to obtain a license to launch a rocket than it does to design and build the hardware itself”the company was offended, in a rare and long press release, in September.

Elon Musk, who, over the years, has made a shift to the right and who now ostensibly supports Donald Trump for the November 5 presidential election, had called on the head of the FAA to resign.

SpaceX is also fighting accusations of environmental pollution, particularly linked to the deluge of water poured during each Starship launch when the engines are ignited, in order to attenuate acoustic waves and thus limit vibrations. This system was added after the first test flight, in April 2023, destroyed part of the launch pad under the power of takeoff, catapulting debris and creating a cloud of dust.

Several environmental associations denounce the damage caused by SpaceX’s operations to animal species, with the space base being installed right next to a protected reserve.
