Starship prototype SN10 returns for a smooth touchdown on a concrete pad on the firm’s facility in Boca Chica, Texas.

SpaceX’s Starship prototype exploded shortly after touchdown for the primary time following a high-altitude flight take a look at on Wednesday.
The reason for the explosion, or whether or not it was intentional, was not instantly clear. Elon Musk alternatively refers to explosions as “RUDs,” or Speedy Unscheduled Disassembly.
The corporate take a look at flew Starship rocket Serial Quantity 10, or SN10. SpaceX aimed to launch the prototype as excessive as 10 kilometers, or about 32,800 toes altitude. There have been no passengers onboard the rocket, as it’s a improvement car and flies autonomously.
The SN10 flight was much like those SpaceX performed in December and February, when it take a look at flew prototypes SN8 and SN9, respectively. Each prior rockets accomplished a number of improvement goals – together with testing aerodynamics, shutting down the engines in succession, and flipping to orient for touchdown –however each prototypes exploded on affect as they tried to land, unable to decelerate sufficient.
Like SN8 and SN9, the purpose of the SN10 flight was not essentially to achieve the utmost altitude, however moderately to check a number of key elements of the Starship system. SpaceX fired all three engines for liftoff after which shut them down one after the other in sequence because the rocket neared the highest of the flight’s meant altitude.
SN10 then transferred propellant from the primary tanks to the header tanks, earlier than flipping itself for the “stomach flop” reentry maneuver – which supplies it a managed descent by way of the air with the rocket’s 4 flaps. Then, within the remaining moments of descent, SpaceX flipped the rocket and returned it to a vertical orientation, firing the Raptor engines to sluggish itself down for the touchdown.
“Third time’s the appeal, because the saying goes – we have had a profitable smooth landing on the touchdown pad,” SpaceX principal integration engineer John Insprucker mentioned on the corporate’s webcast
Starship SN10 lights its three engines and flips earlier than touchdown.

The Starship prototype stands at about 150 toes tall, or concerning the dimension of a 15-story constructing, and is powered by three Raptor rocket engines The rocket is constructed of stainless-steel, representing the early variations of the rocket unveiled in 2019.
“The Texas workforce has a number of extra suborbital take a look at automobiles in construct, with quantity 11 able to roll out to the pad within the very close to future,” Insprucker mentioned.
Musk’s firm is creating Starship with the purpose of launching cargo and folks on missions to the moon and Mars.
Starship is certainly one of two “Manhattan Initiatives” that SpaceX is concurrently creating, with the opposite being its Starlink satellite tv for pc web program. Musk has beforehand estimated that it’ll value about $5 billion to completely develop Starship, though SpaceX has not disclosed how a lot it has spent on this system thus far.
The corporate final month introduced in $850 million in its newest capital fundraise at a $74 billion valuation.
Musk stays “extremely assured” that Starship “might be protected sufficient for human transport by 2023” – an bold purpose given the corporate started the rocket’s improvement and testing in earnest in early 2019.
However Musk’s timeline is essential, as Japanese billionaire Yusaku Maezawa has paid for a Starship flight across the moon by 2023. Maezawa on Tuesday introduced that he’s inviting eight members of the general public to affix his dearMoon mission, which might be a six-day journey to the moon and again.
