SpaceX’s next-generation Starship spacecraft atop its highly effective Tremendous Heavy rocket lifts off from the corporate’s Boca Chica launchpad on an uncrewed take a look at flight, close to Brownsville, Texas, U.S. November 18, 2023.

SpaceX launched its second Starship rocket flight on Saturday, with the corporate pushing growth of the mammoth car previous new milestones.
Liftoff got here a couple of minutes after 8 a.m. ET from its Starbase facility close to Boca Chica, Texas.
Starship flew for greater than seven minutes, efficiently separating from its booster earlier than the rocket’s onboard system deliberately destroyed the car mid-flight.
No individuals had been on board the take a look at flight.
“We’ve got misplaced the info from the second stage … what we do imagine proper now’s that the Automated Flight Termination System on the second stage seems to have triggered very late within the burn,” John Insprucker, SpaceX principal integration engineer, stated on the corporate’s webcast.
The flight termination system is a regular security characteristic in rockets, because it destroys the car if an issue arises or it flies off track. On SpaceX’s webcast, Starship seems to have been detonated at an altitude of about 148 kilometers (or about 485,000 toes). That could be a little beneath half the altitude at which the Worldwide House Station orbits the Earth.
After reaching house, Starship was deliberate to fly a lot of the method across the Earth earlier than re-entering the ambiance and splashing down off the coast of Kauai, Hawaii.
“An extremely profitable day, despite the fact that we did have a ‘speedy unscheduled disassembly’ each of the Tremendous Heavy booster and the ship,” SpaceX high quality engineering supervisor Kate Tice stated on the webcast.
The Federal Aviation Administration cleared SpaceX for a second launch try earlier this week.

SpaceX first launched a full Starship rocket system in April. Though that flight didn’t attain house, it efficiently achieved a number of historic firsts for an experimental rocket of unprecedented scale. The mid-air destruction of the rocket, in addition to an investigation into harm triggered again on the bottom, triggered a regulatory assessment that spanned almost seven months.
The launch try comes on the heels of renewed backlash towards SpaceX CEO Elon Musk over feedback he made on-line. The White Home on Friday condemned what it referred to as “abhorrent promotion of Antisemitic and racist hate” by Musk on his social media platform, X.
Starship system
Starship is each the tallest and strongest rocket ever launched. Absolutely stacked on the Tremendous Heavy booster, Starship stands 397 toes tall and is about 30 toes in diameter.
The Tremendous Heavy booster, which stands 232 toes tall, is what begins the rocket’s journey to house. At its base are 33 Raptor engines, which collectively produce 16.7 million kilos of thrust – about double the 8.8 million kilos of thrust of NASA’s House Launch System (SLS) rocket, which launched for the primary time late final yr.
Starship itself, at 165 toes tall, has six Raptor engines – three to be used whereas within the Earth’s ambiance and three for working within the vacuum of house.
The rocket is powered by liquid oxygen and liquid methane. The total system requires greater than 10 million kilos of propellant for launch.
The Starship system is designed to be absolutely reusable and goals to turn into a brand new technique of flying cargo and folks past Earth. The rocket can be vital to NASA’s plan to return astronauts to the moon. SpaceX gained a multibillion-dollar contract from the company to make use of Starship as a crewed lunar lander as a part of NASA’s Artemis moon program.
Musk beforehand stated he expects the corporate to spend about $2 billion Starship growth this yr.
Targets for second flight
There have been no individuals on board this try to succeed in house with Starship. The corporate’s management has beforehand emphasised that SpaceX expects to fly lots of of Starship missions earlier than the rocket launches with any crew.
SpaceX was trying to surpass the almost 4-minute flight of the primary launch, attain house with Saturday’s try and reveal that enhancements to its floor infrastructure mitigate the harm attributable to the debut try.
In the course of the April launch, SpaceX lit solely 30 of the 33 Raptor engines on the base of the Tremendous Heavy booster. Different engines had been misplaced mid-flight. Moreover, a communications downside led to an sudden delay in triggering the rocket’s Autonomous Flight Termination System, which destroys the car within the occasion it flies off track.
SpaceX launched upgrades to the launch pad infrastructure in addition to the design of the rocket itself for the second try.
