SpaceX Starship prototype rocket explodes after successful landing in high-altitude flight test

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


SpaceX’s Starship prototype exploded shortly after landing for the primary time following a high-altitude flight test on Wednesday.

The reason behind the explosion, or whether or not it was intentional, was not instantly clear. Elon Musk alternatively refers to explosions as “RUDs,” or Rapid Unscheduled Disassembly.

The firm test flew Starship rocket Serial Number 10, or SN10. SpaceX aimed to launch the prototype as excessive as 10 kilometers, or about 32,800 toes altitude. There had been no passengers onboard the rocket, as it’s a growth car and flies autonomously.

The SN10 flight was just like those SpaceX carried out in December and February, when it test flew prototypes SN8 and SN9, respectively. Both prior rockets accomplished a number of growth aims – together with testing aerodynamics, shutting down the engines in succession, and flipping to orient for landing –however each prototypes exploded on affect as they tried to land, unable to decelerate sufficient.

Like SN8 and SN9, the aim of the SN10 flight was not essentially to achieve the utmost altitude, however reasonably to test a number of key components of the Starship system. SpaceX fired all three engines for liftoff after which shut them down separately in sequence because the rocket neared the highest of the flight’s meant altitude.

SN10 then transferred propellant from the principle tanks to the header tanks, earlier than flipping itself for the “belly flop” reentry maneuver – which provides it a managed descent by the air with the rocket’s 4 flaps. Then, in the ultimate moments of descent, SpaceX flipped the rocket and returned it to a vertical orientation, firing the Raptor engines to gradual itself down for the landing.

“Third time’s the charm, as the saying goes – we’ve had a successful soft touchdown on the landing pad,” SpaceX principal integration engineer John Insprucker mentioned on the corporate’s webcast

Starship SN10 lights its three engines and flips earlier than landing.


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 team has several more suborbital test vehicles in build, with number 11 ready to roll out to the pad in the very near future,” Insprucker mentioned.

Musk’s firm is growing Starship with the aim of launching cargo and folks on missions to the moon and Mars.

Starship is certainly one of two “Manhattan Projects” that SpaceX is concurrently growing, with the opposite being its Starlink satellite tv for pc web program. Musk has beforehand estimated that it’s going to value about $5 billion to completely develop Starship, though SpaceX has not disclosed how a lot it has spent on this system to this point.

The firm final month introduced in $850 million in its newest capital fundraise at a $74 billion valuation.

Musk stays “highly confident” that Starship “will be safe enough for human transport by 2023” – an formidable aim given the corporate started the rocket’s growth and testing in earnest in early 2019.

But 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 will probably be a six-day journey to the moon and again.
