The SLS rocket is due for its first launch next week, but NASA's former second-in-command isn't happy about it.
The fanfare surrounding the SLS launch may be giving a misleading impression, according to a former NASA deputy administrator.
Garver said that a test flight is just that.
If this doesn't happen, there is not another test flight planned.
Garver has often compared the SLS with the Starship in her recent memoir and interviews. Before NASA got on board, Garver was an early backer of the company.
She believes that the public will soon see that contrast.
Garver said that it would become embarrassing if Starship launched dozens of times a year like Falcon 9 and SLS.
Garver offered two embarrassing scenarios for NASA, one of which was that the SLS simply doesn't perform as planned.
What do you think? If the first person doesn't go well, you're going to put them on one in two years. Garver has never heard anyone talk about that plan.
It's definitely not out of the realm of possibility, and we'll know soon if she's right about the SLS test launch.
There was a former NASA official who tried to stop the SLS.
NASA's moon mission this month will shoot a probe, which will contain life into deep space.
