Speculation is they would do a bunch of tests with the potential to destroy it; cryogenic tests, pressure tests, static firing (probably with three raptor engines instead of one) and build it the rest of the way up. That would be followed by some verification tests before a hop to much higher altitudes than the previous tanks have hopped. <br /><br />Starship is going to have a unique flight profile before landing. Sort of a belly flop for air resistance, followed by a vertical flip while lighting the engines and then landing nose up with the Raptors firing. They need to take it high to get enough time and speed to test that maneuver. <br /><br /> <br />They're scheduled for a road closure and testing overnight tonight. It seems possible they test to tank failure, then roll SN8 to the pad while cleaning up the SN7.1 mess goes on. <br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-44529881096763865232020-09-21T14:27:38.651-04:002020-09-21T14:27:38.651-04:00Over at Teslarati, there is speculation that SN8 m...Over at Teslarati, there is speculation that SN8 may be rolled to the test stand since the hydraulic test rams were move to the launch use test stand closer to the tank farm. The thinking is that SN8 will undergo initial ambient and cryo pressure tests and then be moved back for installation of the fins and nosecone. Glad they are moving on quickly.BillBhttps://www.blogger.com/profile/17593147581583316765noreply@blogger.com
