Ideally, launch, recovery, and refurbishment site should all be the same place. Pat I agree with you Pat, but JR's point is well taken. For historical reasons the refurbishment point is probably not at the AFS on the Cape. Maybe it could be moved there, eventually. But since I suspect leasing space at the AFS might come at a premium, SpaceX is probably already set up to do the refurb elsewhere. Now if the flight rate becomes high enough that could change. Rick Jones mentioned Hawthorne CA. Presumably that is where SpaceX will do the refurb on Dragon initially? So that means continued landing ops in the Pacific near San Diego and specifically the wharves around Long Beach? Given the location of Hawthorne and surrounding environs, doesn't look too promising for conversion to land landings anytime soon. Water landings definitely at an advantage here not to mention capsule simplicity. Dave |

Water landings definitely at an advantage here not to mention capsule simplicity. SpaceX seem to have worked out how to get a new Dragon from Hawthorne to Florida. They should, therefore, be able to work out how to get a used dragon from some flattish empty bit of the US South-West to Hawthorne. There will be, indeed, a new spaceport in New Mexico or thereabouts. And, at worst, they can recover it by helicopter from land as easily as they can from sea, or more so. -- (c) John Stockton, nr London, UK. Turnpike v6.05 MIME.

That should help reduce costs. What are their landing options in case of bad weather at the primary landing site? Dave Land somewhere else? Sylvia. Since they're flying on human blood as their fuel and everything else, they get to land anywhere they like, as well as they get as many do- overs as they like. ~ BG |

Mid Sunday afternoon here. Droll Sylvia... Care to clue us in as to 'where' else is? Central Park in Manhattan? It appeared to me that a craft that returns by parachute and descends pretty much vertically onto shock absorbing landing gear doesn't really have much in the way of requirements for its landing area, beyond being reasonably large, moderately flat, and devoid of significant obstacles. There would have to be plenty of suitable places, including most of Australia (might not be reachable from the particular orbit, but that's another matter). Sylvia. They could always land in central Antarctica rather than the Arctic that's becoming open water. I bet Russia has a low cost landing fee. A lot of land was recently cleared by Katerina. ~ BG |

I thought the ISS routinely passes over Australia? So what would you charge SpaceX for landing rights to your back yard? Would they need venomous snake and/or other large carnivorous reptile insurance? :-D Such risks are grossly overstated. The main concern would be that the astronauts would be bundled into an off-shore immigration detention centre and lost in the system before anyone considers the possibility that they weren't actually claiming refugee status. Sylvia. Good one. ~ BG |
