SpaceX could also be on the cusp of launching its huge Starship rocket for a 3rd time, probably as early as subsequent Thursday. In a web-based replace, the corporate stated it’s focusing on Thursday, March 14 for the third flight take a look at of Starship “pending regulatory approval.”
Whereas SpaceX didn’t publish a launch time on its web site, a livestream submit on X (previously Twitter) confirmed a begin time of seven:30 am EST (6:30 a.m. CST, 1230 UTC). Coupled with SpaceX stating that its broadcast would start about half-hour previous to liftoff, that means a goal launch time of 8:00 a.m. EST (7:00: a.m. CST, 1300 UTC).
The mission continues SpaceX’s iterative method to creating its Starship rocket, which entails flying as a lot as doable and getting by as a lot of its mission profile as it could. SpaceX is hoping to push plenty of boundaries for the car with this flight.
On the Ship 28 higher stage as an example, SpaceX goals to check the payload door, conduct a re-ignition of a number of Raptor engines whereas in area and conduct a propellant switch demonstration in the course of the coast part.
Having the ability to exhibit propellant switch in area is vital not solely to SpaceX’s future ambitions, but additionally to NASA’s Artemis program. Whereas this flight will carry out the switch inside Ship 28, the following huge leap might be a ship-to-ship switch.
SpaceX might want to launch a number of Starships in an effort to gas a tanker on orbit. That tanker will then be used to shift that propellant to the Human Touchdown System program’s model of Starship, which will carry astronauts right down to the floor of the Moon and again up once more.
In February, NASA and SpaceX had been busily testing docking mechanisms that can enable its Orion spacecraft to dock with the HLS Starship whereas in lunar orbit. They carried out the work at NASA’s Marshall Spaceflight Heart, the NASA set up the place the HLS program relies.
Whereas this third flight take a look at gained’t embrace a payload, SpaceX wants to achieve orbit to attain its said targets. Throughout an organization discuss given earlier this yr at Starbase in southern Texas, SpaceX founder Elon Musk defined why they imagine Starship failed to achieve orbit throughout its second flight take a look at.
“Flight 2 nearly truly made it to orbit. Actually, satirically, if had had a payload it will’ve made it to orbit,” stated SpaceX founder Elon Musk throughout an organization discuss earlier this yr. “The rationale that it didn’t fairly make it to orbit was as a result of we vented the liquid oxygen and the liquid oxygen finally led to fireside and an explosion.”
“We wished to vent the liquid oxygen as a result of we usually wouldn’t have that liquid oxygen if we had a payload. So satirically, if it had a payload, it will’ve reached orbit. And so, I believe we’ve bought a very good shot of reaching orbit with Flight 3,” he added.
SpaceX famous in its launch announcement that Starship will launch on a brand new flight path that can see it goal a splashdown within the Indian Ocean roughly an hour after liftoff.
“This new flight path permits us to try new strategies like in-space engine burns whereas maximizing public security,” SpaceX stated in a press release.
Classes discovered
Previous to Wednesday’s announcement of Starship’s subsequent launch date, SpaceX revealed a weblog submit, providing some perception into what it discovered concerning the second flight take a look at of Starship. It pointed to one of many 33 Raptor engines on the Tremendous Heavy booster that “failed energetically” in the course of the 13-engine boostback burn, which brought on the car to blow up roughly 3.5 minutes into flight.
“The most probably root trigger for the booster [rapid unscheduled disassembly] was decided to be filter blockage the place liquid oxygen is equipped to the engines, resulting in a lack of inlet stress in engine oxidizer turbo pumps that ultimately resulted in a single engine failing in a method that resulted within the lack of the car,” SpaceX said. “SpaceX has since carried out {hardware} adjustments inside future booster oxidizer tanks to enhance propellant filtration capabilities and refined operations to extend reliability.”
Addressing this was a part of the 17 motion objects established by the SpaceX-led mishap investigation following OFT-2. On Feb. 26, the identical day SpaceX revealed its weblog submit, the Federal Aviation Administration (FAA) notified the general public that it closed the mishap investigation.
It outlined seven corrective actions wanted for the Tremendous Heavy Booster and ten for the Starship higher stage. As a part of these actions, SpaceX famous that it will introduce “new digital Thrust Vector Management system for Starship’s higher stage Raptor engines and [improve] the pace of propellant loading operations previous to launch.”
Earlier than Starship can fly for a 3rd time, SpaceX might want to obtain a license modification from the FAA. For a timescale comparability, forward of the second flight take a look at of Starship, the FAA introduced the completion of the protection overview portion of the launch license analysis on Oct. 31, 2023, and the U.S. Fish and Wildlife Service wrapped up its formal session on Nov. 14. That paved the best way for a launch license to be issued from the FAA to SpaceX on Nov. 15.
Following a moist costume rehearsal tanking take a look at on Oct. 24, SpaceX posted an identical replace to social media as its most up-to-date one from Wednesday morning. It said that Starship was prepared for its second take a look at flight “pending regulatory approval.”

That was adopted by one other submit on X on Nov. 3 stating their hopes of launching “as quickly as mid-November, pending regulatory approval.” SpaceX’s subsequent submit to X relating to Starship got here on Nov. 10, stating “Starship making ready to launch as early as November 17, pending remaining regulatory approval.”
SpaceX confirmed the meant launch date of Nov. 17 as soon as the launch license was formally authorized on Nov. 15. The launch itself pivoted to Nov. 18 as a consequence of a difficulty that got here up with a grid fin actuator on the Tremendous Heavy Booster.
Provided that that is the third flight take a look at of Starship and never practically as a lot wanted to vary between flights two and three as did between one and two, the declaration of a March 14 launch date with out having a launch license firmly in hand might show to be true.
Nonetheless, remaining regulatory approval remains to be being decided by the FAA. A spokesperson instructed Spaceflight Now on Wednesday that they didn’t have an replace to offer on the development in direction of issuing this third flight license.
So for now, it and the launch stay pending.
This third Starship launch would considerably break our report for the hole between second and third flights of a brand new launch car, which had higher than a yr hole for each Falcon 1 and Falcon 9. Let’s go!
