Wall Street Journal: The Harassment of Elon Musk (Paywall)
Does the Biden Administration have it in for Elon Musk? We’ve sometimes tussled over policy with the Tesla and SpaceX CEO, but the volume of government investigations into his businesses makes us wonder if the Biden Administration is targeting him for regulatory harassment. ... But the collection of probes into Mr. Musk’s ventures are unusual enough to suggest what the Justice Department likes to call a “pattern or practice.” We doubt any order from on high has been sent, but it doesn’t need to be when a figure becomes Progressive Enemy No. 1.

both are available at a decent grocery store - not really endangered species... That said, not sure if they had the right fishing and hunting licenses. Then again, neither are migratory - so they are state licenses, not federal.

There is a certain distance from a starship launch where quail eggs and crab are cooked perfectly by the launch.
SpaceX calls this the flavor zone.. |

NSF Live: Eric Berger - Starship Flight 2 and the Big Falcon 9 Surge |
|
|
View Quote Highlights: Berger's writing a sequel to "Liftoff", which will cover the second decade of SpaceX (from after the Falcon 1 to Demo-2). Berger thinks that the FAA wouldn't say "it'll probably be ready by the end of October" if they didn't feel USFW would be done with their review by then. "So we've probably got another 6-8 weeks before Flight-2". Wildcard is a potential government shutdown, which would likely halt all regulatory processes for an arbitrary time. Starship will take a long time to replace Falcon 9, due to the sheer efficiency of the F9 operation. Blue Origin's lunar lander is "about a decade out". HLS-Starship probably won't be ready before 2027 or so. NASA has no other options. "If they are going to the Moon anytime in the 2020s, it'll be using Starship-HLS". Nonzero chance that NASA will move to cut SLS' throat as soon as Starship (and/or New Glenn) is reasonably operational. |

Something to consider. When we start seriously going to Mars we are going to need to build launch pads there if we want to get back. Probably not quite as dense as this because it doesn't need as much Delta V to get off the surface. But still, this is snot going to be easy.

View Quote I wonder how thick of a launchpad would be needed to support starship considering the lower gravity of mars and thrust of the engines should be less focused because it doesn't have 1bar of atmosphere pushing on it. I have read about fiber reinforced concrete in the past, maybe a composite of Mars soil + carbon fiber + vacuum rated binding agent could be used. With the considerably lower atmospheric pressure wouldn't it be better to use vacuum rated engines for Mars takeoff and landings? With the lower pressure and wider rocket nozzles wouldn't the rocket exhaust be much wider and less concentrated for a mars launch? If you don't use sea level engines on Mars, wouldn't it be better to custom build mars starships without sealevel engines? Schlepping around engines just because you want to land on Earth seems inefficient. Time to build some orbital space stations to handle mars bound freight! Just avoid space station 13 I hear it is run by madmen. ETA has anyone tried any high voltage experiments on Mars? I'm wondering how high voltage reacts in a near vacuum atmosphere with a lot of carbon... is it like the inside of a neon bulb? |

This thread was started in December 2018. View Quote I think that Lunar Cyclers might be worthwhile, in the mid-to-long-term, as it would save on fueling loads for Starship. You could have a couple of small transfer vehicles for dashing out to rdv with (and return from, on the way back) the Cycler, and then to drop into LLO to meet up with HLS. Mars Cyclers.......going to be an awful long time before we have the kind of sortie rate to Mars to require something beefier than Starship or a purpose-built Mars Transfer Vehicle (and a Mars Cycler would be a lot harder to maintain and PMCS than a Lunar Cycler). |

View Quote Such a thing is going to demand nuclear engines and even though contracts have been issued for small experimental ones, that is a technology that is going to demand a lot of careful work before a human is sitting close to. Time and resources, that said I think this is just about the acme of "expensive but worth it." As silly as this may sound I think our big limiting factor right now is human imagination. Most people seem to expect that humanity is going to either descend into a Mad Max nightmare future or it will be like Star Trek. I don't think the future is going to look like either of those scenarios. What I think it will look like is something that is rarely depicted and when it is, it's rarely in a movie or tv show. Its in some novel. If we can't imagine the future then at the least it's going to come as a huge shock when it arrives and people are already clearly getting tired of future shock. Perhaps the answer to all this will wind up being people living an Amish existence with all manner of advanced tech humming away invisibly in the background? |

Deep space starship does not need fins, heat tiles, header tanks or sea level engines assuming the booster flings the starship high enough. But they probably need solar panels, robust environmental systems, radiation shielding, micrometer shielding, heat sinks, deep space comm system and strong locks on the airlock to keep people from taking a walk after being stuck in a fart can for months. |

Originally Posted By Hesperus: Such a thing is going to demand nuclear engines and even though contracts have been issued for small experimental ones, that is a technology that is going to demand a lot of careful work before a human is sitting close to. View Quote Ehhh..... For Lunar Cyclers, NTR or Nuclear Ion would be nice, but not necessary (basic chemical rockets would be fine since the LEO/LLO-to-Cycler shuttle could be kept pretty small and spartan). A nuclear-ion or NTR orbital tug for moving big cargos around in cislunar space is going to be needed, though (we've known that since the 70's). For Mars Cyclers.....again, depends on the orbital mechanics (Mars is still within the realm where solar power is enough for space purposes, but surface activity will need nukes). Starship would be a cool RDV vehicle for each end of the Cycler's loop. NASA (and DARPA/DOD/USSF) have at least two NTR engine programs running, one of which (DRACO) is scheduled for a space-side demo flight in 2027 (LockMart is the contractor). Human's will (eventually, once a full-scale engine is available) likely be "sitting" pretty far from the hot parts (likely on the other side of a shadow shield). The challenge is designing a long-endurance fission core that will do what we want it to do (superheat a fluid, likely Hydrogen) and work reliably in microgravity for years (not crapping out in mid-maneuver and sending our Space Heroes to their lingering doom). Fission ain't a new tech, and we have had NTR rockets working (50+ years ago). The chief obstacles were (a) political and (b) that we weren't doing anything that required NTR engines (once we retrenched back to LEO after Apollo....NTR was kinda irrelevant). Now that the N-word is less scary to Congress and the public at large ("Hey, those crazy Russians shoot at nuclear plants! They must be safe!!!"), and we are breaking out of LEO, NTR is likely to be a real thing before 2030. |
