Musk: SpaceX is now targeting late February/March for 1st orbital launch of Starship
According to a tweet put out by Elon Musk on January 8, 2023, SpaceX is now targeting late February/March for 1st orbital launch of the 24th prototype of Starship and the seventh prototype of Superheavy.
The testing in 2022 has not gone as smoothly as hoped, and is the reason no launch occurred last year:
Super Heavy B7 first left SpaceX’s Starbase factory in March 2022 and has been in a continuous flux of testing, repairs, upgrades, and more testing in the nine months since. The 69-meter-tall (~225 ft), 9-meter-wide (~30 ft) steel rocket was severely damaged at least twice in April and July, requiring weeks of substantial repairs. But neither instance permanently crippled the Starship booster, and Booster 7 testing has been cautious but largely successful since the rocket’s last close call.
Following its return to the OLS [orbital launch site] in early August, Super Heavy B7 has completed six static fire tests of anywhere from one to fourteen of its 33 Raptor engines. It has almost certainly dethroned Falcon Heavy to become the most powerful SpaceX rocket ever tested. And on January 8th, 2023, SpaceX rolled the rocket back to Starbase’s orbital launch site for the seventh time. According to statements made by CEO Elon Musk and a presentation from a NASA official, the last major standalone test between Booster 7 and flight readiness is a full 33-engine static fire. Together, B7’s 33 Raptor 2 engines could produce up to 7600 tons (16.7 million lbf) of thrust at sea level, likely making Starship the most powerful rocket stage in the history of spaceflight.
I had read speculation earlier that it was impossible for SpaceX to do a full 33-engine static fire test because the OLS could not hold the rocket down. That now appears to be incorrect.
Musk’s tweet and proposed schedule should also not be taken with great seriousness. He routinely sets ambitious targets merely to keep the pace fast, even if those targets are not met.
