Quote HistoryQuoted: well... I mean not even the titular Enterprise was the first ship of its line. Original Trek Enterprise was a Constitution class vessel. The first ship of that line was named the Constitution. Next gen... it was a Galaxy class... updated one for the later movies was a Sovereign Class. I'm not sure... but maybe the one from Enterprise ... since it was an experimental prototype ship might have been the only time the Enterprise was the first ship in a line. Quote HistoryQuoted: Quoted: No, it should become a tradition that the first spaceship of a line that is American made should be named Enterprise.

I'm not sure... but maybe the one from Enterprise ... since it was an experimental prototype ship might have been the only time the Enterprise was the first ship in a line. Has Star Trek established that class naming convention in canon, or is that just a reasonable assumption based on modern conventions? |

Quote HistoryQuoted: Has Star Trek established that class naming convention in canon, or is that just a reasonable assumption based on modern conventions? Rando tangent. Reason number 23 why I detest Star Trek Discovery. Discovery is a Scott Crossfield class starship. Not only is that, (at least in my book) dishonoring the memory of my favorite test pilot. There is no USS Scott Crossfield in that fictional universe. The only ships of that class were the USS Discovery and the USS Glenn.  Attached FileFind me an uglier and more glitchy spaceship in all of fiction than this POS. Star Trek naming conventions are a mess. In canon there are 2 Miranda class starships with the name Saratoga. Edit. If anyone ever makes a Scott Crossfield class starship it had better be impressive looking and fast as fuck. I've even played around with a story idea of a 'spore drive' but used strictly as a navigational system. Not a way of powering a ship. Another edit. Crossfield helped in the designing and was the first test pilot of the X15. Outlaw Star did a decent job of creating a fictional updated and enlarged X15.  Attached File Attached File Attached File |

Not that I ever laid that level of attention. I want to say the Enterprise was the third one. Galaxy and Yamato were made first. I think the Odyssey from DS9 was the only other one given a name. You saw a few in formations and fleet battles toward the end of DS9. |

Isn't his concern with the booster and not the capsule's return? The booster wasn't doing that when it came in. I am not sure what the ISS's velocity has to do with it. Thanks |

Elon Musk's biggest worry about SpaceX's first astronaut mission isn't the rocket launch — it's the spaceship's return to Earth
"Musk added that while the threat was low, his "biggest concern" about the new spaceship was the capsule's asymmetric design, which is driven by its emergency escape system. While screaming back to Earth at 25 times the speed of sound, the capsule's heat shield will deflect and absorb the energy of superheated plasma — but the forces of atmospheric reentry have a slim chance of causing catastrophe." "If you rotate too much, then you could potentially catch the plasma in the super Draco escape thruster pods," Musk said, adding this could overheat parts of the ship or cause it to lose control (by wobbling). "We've looked at this six ways to Sunday, so it's not that I think this will fail. It's just that I worry a bit that it is asymmetric on the backshell." |

Quote HistoryQuoted: Quoted: ISS orbits at 4.76 miles / second. That’s more like Mach 25. It's mostly out of the atmosphere. Although there is some atmospheric drag even at that altitude necessitating occasional boosts. I had the good fortune to fly the full motion Shuttle sim two times. We flew several launch abort and reentry profiles. On one of the reentry profiles we were just at the edge of the atmosphere and the airspeed tape was dead. We were showing Mach 32 with 0 indicated airspeed. As we started to just bump the upper air the airspeed started to just barely move 1-2 knots Mach 25. As soon as we had airspeed the computer switched from reaction jets to aerodynamic control surfaces. The switch was flawless, we proceeded to fly it to touchdown KSC. |

Quote HistoryQuoted: It's going to be refurbished and flown again. SpaceX will continue to need new first stages to replace those that are lost due to failures like two earlier this year. With as many Starlink launches as they will need and as few astronaut launches each year, I don't see a problem. |

It is well known that Musk is more than just a figurehead. He doesn't call himself the CEO or such, he calls himself the Chief Designer (something like that) because he does go to the CAD, table, and back of a napkin often.

do they bring the legs to 90deg to assist with aerodynamic braking?
