SpaceX is making preparations for the sixth take a look at flight of the world’s strongest rocket, Starship. Elon Musk’s firm has been taking a “fail fast, learn fast” strategy to analysis and improvement extra akin to the world of Silicon Valley than the aerospace trade, and the tempo of launches solely seems to be dashing up.
When is the subsequent flight?
SpaceX says on its web site that it goals to conduct the sixth take a look at flight of Starship on 19 November, with a launch window opening at 4pm Central Time (10pm UK). A livestream of the launch will likely be broadcast on SpaceX’s X account, the social media platform additionally owned Musk, or it is possible for you to to look at it right here at newscientist.com
It took SpaceX 18 months to hold out the primary 5 Starship take a look at flights, with the fifth happening in the course of October. If the corporate carries out the sixth subsequent week, it would imply a spot of simply over one month for the reason that final flight – its quickest turnaround but.
What is going to SpaceX try in flight 6?
In some ways, flight 6 will likely be a repeat of flight 5, however with just a few key variations.
The booster stage will once more try a “chopstick” touchdown, wherein the craft is grabbed and secured because it returns to the launchpad, permitting it to be lowered to the bottom. This strategy is designed to ultimately permit the booster to be re-used a number of instances and massively cut back the price of placing payloads into orbit.

The higher stage will attain area, perform a partial orbit after which re-enter Earth’s environment for a splash touchdown within the Indian Ocean. However this time, the higher stage will try and reignite one in every of its Raptor engines whereas in area to be able to gather useful operational knowledge. It’ll additionally take a look at new warmth defend designs throughout re-entry.
One other distinction is that the launch will happen later within the day in order that the touchdown of the higher stage within the Indian Ocean might be filmed in daylight, making certain higher element. Earlier missions have seen night time landings and due to this fact footage – whereas cinematic and dramatic – hasn’t given engineers as a lot perception as video of a daytime touchdown will.
What occurred throughout earlier Starship launches?
Take a look at flight 1 on 20 April 2023 noticed three of the booster stage’s 33 engines fail to ignite. The rocket later span uncontrolled and self-destructed.
The second take a look at flight on 18 November 2023 obtained additional, gaining sufficient altitude that the booster and higher phases separated as deliberate. The booster stage finally exploded earlier than reaching floor degree and the higher stage self-destructed, though not earlier than efficiently reaching area.
Take a look at flight 3 on 14 March 2024 was at the least a partial success, because the higher stage reached area as soon as extra, nevertheless it didn’t return to floor degree intact.
The subsequent flight, on 6 June, noticed the higher stage attain an altitude of greater than 200 kilometres and journey at over 27,000 kilometres per hour. Each the booster and the higher stage accomplished mushy splashdowns within the ocean.
Take a look at flight 5 was essentially the most formidable up to now, with Starship’s Tremendous Heavy booster dropping again to the launch pad and being safely caught by SpaceX’s launch tower, referred to as Mechazilla, in a pair of “chopsticks”. It’s geared up with a pair of “chopsticks” to seize the craft at a selected level and safe it, permitting it to be lowered to the bottom.
