That may be one reason they are so readily replacing them after static fires and then analyzing the physical area of the issue.BillBhttps://www.lastfrontierinbandera.comnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-37762746335766559392021-03-20T13:19:30.666-04:002021-03-20T13:19:30.666-04:00In the case of the "crazy Elon" landing ...In the case of the "crazy Elon" landing maneuver, I can appreciate that pulling off a new maneuver that no one has ever done may not model well in the software. The vehicle moves approximately as it should, but getting all the fluids in the system into the right place seems like the problem. <br /><br /><b>But</b> (big but) it seems at least one Raptor out of every set put on a prototype needs to be replaced. OK, partial credit again because it is in active development but if 1/3 don't work right, how long will it take them to get a set of 28 on Super Heavy to work? Put on 28, replace 9. Then replace 3 of the replacement 9 and 1 of the the final 3. Overly simplistic analysis of something best done with a Poisson distribution - but you get the point. Yeah, the Raptors don't look ready for prime time. <br /><br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-68194728950679335072021-03-20T13:11:53.100-04:002021-03-20T13:11:53.100-04:00I thought it wouldn't be hard to lift the roof...I thought it wouldn't be hard to lift the roof on the high bay and add in another couple of hundred feet, so it's interesting they're going with cranes to hoist the Starship on top of its booster. <br /><br />BN1 doesn't have legs, and we don't know what they're planning to do. We know Elon thinks they should land without deploying legs, but have a tower catch it by the grid fins. It's hard to imagine that working the first time, so I think the first couple of boosters, will land on legs. Or they don't care if they crash the first few boosters trying to catch them. <br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-63325572508830548032021-03-19T22:18:16.674-04:002021-03-19T22:18:16.674-04:00They're actually laying the foundation for two...They're actually laying the foundation for two 450' tall cranes at Boca Chica.Beanshttps://www.blogger.com/profile/15293778848879361153noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-56590368190102012402021-03-19T22:14:24.239-04:002021-03-19T22:14:24.239-04:00I am not a rocket scientist (ianars) but is seems ...I am not a rocket scientist (ianars) but is seems some more attention to engines and fuel systems would be a good idea. Testing by explosion seems needlessly extravagant.

Someone commenting on the audio from Labpadre stated that he had a friend who was being hired as part of the crew that is going to build it. There seem to be preparations near the orbital launch pad to build something else that needs good foundations.BillBhttps://www.lastfrontierinbandera.comnoreply@blogger.com
