Accidentally producing the polar opposite of Starship serial number 9 (SN9) finishing a trio of Raptor auto evaluations in four hours each week, SpaceX has now suffered three back-to-back static fire aborts on January 20th.
On January 13th, Starship SN9 somewhat successfully ignited its Raptor engines three individual times with zero hands on human evaluation or intervention. Even though an impressive accomplishment, SpaceX CEO Elon Musk shortly revealed that among the enemy ’s three engines have been damaged during the test campaign. NASASpaceflight.com afterwards reported that the business had detected an issue with a single Raptor following the first three-engine static flame, finally firewalling it and performing the subsequent two stationary fires with only two engines.
Two of the engines need minor fixes, so will be changed out

SpaceX originally allocated five days to replace both damaged Raptors (SN44 & SN46), scheduling street closures (a telltale indication of test plans) on January 18th, 19th, and 20th. Windows around the 18th and 19th went with zero attempts. At length, on the 20th, SpaceX kicked off Starship SN9’s first real test attempt since the motor swap around 2pm but it was aborted by 3pm.

Following a very brisk recycle, Starship probably made it less than a minute away from ignition however, the next attempt was finally aborted around 3:40 pm.

2 hours later, after SpaceX extended the conclusion of its street closure from 5pm to 8pm, Starship SN9’s third Raptor static fire attempt was also aborted – once more just a minute or less from ignition.

SpaceX held Starship SN9 for an hour or so after the next abort but finally started final detanking and depressurization around 6:50 pm, marking the close of the day’s attempts.

It’s ’s not possible to say what caused Wednesday’s back-to-back-to-back aborts or if the 3 instances were connected. While possibly frustrating to observe from the sidelines, it’s critical to keep in mind that the public is getting a truly unprecedented continuous belief of SpaceX’s procedure of developing and refining a world-class launching vehicle. In addition, each and every Starship suffers should produce volumes of valuable information that both Starship and Raptor teams may use to better understand how to design, construct, test, and operate the cutting edge vehicle and its engines.
More likely than not, SpaceX is leaning towards warning (and thus cautious hardware and software limitations ) while trying to prepare Starship SN9 because of its authentic data-gathering purpose – an SN8-style high-altitude launching and landing attempt.

SpaceX is currently scheduled to try again with another set of Starship SN9 inactive fire attempts between 8am and 5pm CST (UTC-6) on Thursday, January 21st.

Meanwhile, prior to SN9’s multiple Wednesday aborts, SpaceX gathered the most recent in a collection of Starship ‘test tanks’ from the mill to the launch pad. A team immediately secured the tank to the cement pad and connected it to ground support equipment in preparation for a set of evaluations which will probably finish with SpaceX intentionally pressurizing the tank before its own extremities. When effective, it is going to open the door for prospective Starships to conserve weight by cutting edge steel epidermis thickness from 4mm to 3mm.
Stay tuned for updates on the two active test campaigns.
