Some additional bad news about that Boeing Starliner test that never made their mission to the ISS is out today. They had thruster failures.<br /><br />SpaceX is acting as the Great Disruptor.

And they learn from their mistakes.Beanshttps://www.blogger.com/profile/15293778848879361153noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-69636153961153778882020-01-20T11:50:33.542-05:002020-01-20T11:50:33.542-05:00I'm fervently hoping that NASA doesn't del...I'm fervently hoping that NASA doesn't delay the mission so that Boeing can beat SpaceX with the first manned flight. After all their hard work and dedication, SpaceX deserves to bring home the flag that the last shuttle mission left on ISS (the same flag that was launched on the first shuttle mission).<br /><br />Boeing's performance on the <i>Starliner</i> program has been careless, clumsy, and offhand. They deserve to lose (and I say this after spending 27 years working there in research and development).Malatropenoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-26467947346500892732020-01-19T21:05:45.458-05:002020-01-19T21:05:45.458-05:00"You know we're going to blow up a perfec..."You know we're going to blow up a perfectly good rocket for this, right?"Ritchiehttps://www.blogger.com/profile/08075903551422300106noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-67138620180211733452020-01-19T17:26:27.030-05:002020-01-19T17:26:27.030-05:00SpaceX makes me smile.

One thing that came up in the News Briefing is that NASA may want to make Demo 2 an extended stay mission. That may delay SpaceX Demo 2 so that they can train the astronauts to perform ISS mission tasks.BillBhttps://www.blogger.com/profile/17593147581583316765noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-19681890205763631312020-01-19T16:30:15.629-05:002020-01-19T16:30:15.629-05:00I don't think they blew the booster with the F...I don't think they blew the booster with the FTS (Flight Termination System). At least they didn't indicate so in the New Briefing at 12:00 EST.
