Put me in for a gas giant habitable moon. You gain the benifits of a supermassive magnetic field from the giant, and stave off small-star tidal locking by locking to the giant instead.
-
Going a bit more high tech, I remember reading about "plasma walls" that use magnetically contained plasma to block leaking air. Given a narrow gap of a bearing, do you think this approach would be effective? -
Can you follow his line of reasoning, at least? Mars Direct had a launcher, mars injecter, habitat, lander, ascent vehical, return vehical, and reentry vehical, all separately designed and integrated. MCT has a RTLS lowerstage, a giant supercapsule upperstage, and a supercapsule varient modified as a tanker, to refuel the supercapsule in orbit, and that's it. By using the same design to do multiple things, spaceX saves money.

Cant you just put a "frame" on your asteroid-circling bag, so it looks like a dodecahedron, soccerball, or other geodestic?
-
Even for manned missions, it has many of the benifits of a Cycler Habitat- By putting all the high-mass stuff on the mothership into this kind or orbit, it doesnt need to do a martian insertion while letting the slimmed down lander handle taking the crew to pre=prepared martian habitaats, until the mothership comes around again.

spaceX was founded because Elon wanted to spend -his own money- on a publicity stunt (no buisness plan at all) to put a greenhouse on Mars. And NASA quoted him a price that someone tied for 100th richest person in the world couldnt afford. Once he can afford it, (by making getting to mars cheaper) putting a greenhouse on mars will be the LEAST of what he does.
-
it's periapse was raised by all the debris it swept up clearing it's orbit.
-
On the full scale separation test, on the counterweight... is that a Thwomp? Like from Mario?
-
Space battles will they be point blank?

I think that, stripping out all the political mess, that's exactly how it would go. Mars has all the defensive advantages right up until earth controls the martian orbitals. -

Martian sepratists. Its too far to walk. -

https://en.wikipedia.org/wiki/Point-blank_range In any kind of orbit, point blank will be quite short, as the bullet will be ina completly different orbit than either the firing or target ship. For Lasers, on the other hand, Point blank will be lightseconds away, and if the arget has enough DV to maintain evasion, you CAN miss from beyond that range. -
They had a survey probe- it was on spaceX's one launch failure.
-
Different orbits. Decades ago we didnt even know about the objects we're now using to infer PlanetX's existance.
-
Elon Musk is on record as wanting to colonize mars. He's a majority stockholder of an up-and-coming orbital launch provider, SpaceX. He has the motive and the means. Any hardware he develops with mars capability will have secondary use closer to home. I feel he doesnt need to have an economic incentive to colonize mars- To put it cold-bloodedly as possible, he just wants to open a new market. Setting up the colony is a loss leader for the profitable effort to supply them.
-
I seem to recall SpaceX having a fairly ridiculus waitlist. They're going to need to work through that.
-
If you need to spend an extra million on the launcher to save two (out of like 12 million) in conruction costs, is that worthwhile?
-
SLS's problem is that it's cheaper to make something smaller and use a different, cheaper rocket. With Falcon Heavy, you can save money by making something BIGGER, less efficent. Dont need micromilimeter machined parts of spaceage materials- just build something that does what you want and ride a bigger (but still relatively affordable) rocket.
-
There's apparently some relly technical resonant-orbit type stuff involved. Almost everything we see is stable over astronmical timelines with a planet of mass (earth x10) in that orbit- the stuff that would be unstable and swept up, is missing.
-
Which is why SpaceX is focused on building better ships.
-
Rigid citybag with supplementary cablebags, I'd think.
-
Well, we have an orbit for the hypothetical object- an infrared scan along the track should find SOMETHING..
-
Well, the balloon isnt under pressure, so it wont be a big blowout like Mark Watny's Airlock-cannon. it'll take time to lose lifting gas (unless the rip is at the very top of the balloon, but it still has to "burp" if the baloon is at all rigid) and since breathing air is also a lifting gas the habitat has a very low terminal velocity. (large cross section + low effective weight)
-
Interesting. They havnt found it, but they have a simulated orbit+mass that explains what they set out to explain, plus a bunch of other things that concidently fit their simulation that they were not trying to explain.
-
Actually, the half million coach price WAS for a 1.5 year round trip. It explicitly includes free passage back. And that hundred tons to mars is a 100 passanger load. Clearly there's some form of recycling involved.
-
The MCT is supposedly aiming for a more efficent price point- supposedly half a million for "coach", so call it a million or two breakeven, and tourists in first class pay more.
