Canopus

Maybe if they cancel Em-1. But i‘m sceptical.

they don‘t propose to build the satellites or mine the moon, but to provide transportation in case such space based business models arise. Anyway this is really the wrong thread for this discussion.

The idea isn't to return recources to earth from the Moon but to use them in space without having to lift them from the earth. Also why would Solar power satellites contribute to global warming? All in all this model for a cislunar economy would contribute more to the advancement of humanity than some remote Mars colony that doesn't return any value, atleast in my opinion (also a lot more realistic). This is the wrong thread for Cislunar-1000 though.

Will Zubrin volunteer for the first Mars flight in Elon‘s Magic BFR? Edit: Found this article about the ITS from Zubrin himself with some interesting criticism: http://www.thenewatlantis.com/publications/colonizing-mars

More about the reusable lander concept: http://spirit.as.utexas.edu/~fiso/telecon10-12/Post-Donahue_9-7-11/Post-Donahue_9-7-2011.pdf a little bit older but the same concept should still work at the NRHO.

My guess is that the ion engines are the reason for the DST to be serviced and launched from a lunar orbit and not LEO. So while you wouldn’t necessarily need the DSG you still need SLS and Orion to get your crew and cargo there.

Totally different environment though.

Its a total of 13 launches but only Phase 2 and 3 have to do with preperations for a Mars flight. The rest are DSG mission. Have you read the document?

Its not 13 Launches for the Mars mission though.

One Mars Mission would be two Launches. One for the DST and later just the Fuel, and one for Crew and Logistics. As for the Lander i can‘t seem to find it in the document but i wouldn‘t say more than two launches. All in all still less than Constellation proposal. As for the Lunar lander, this proposal is not for the reusable lander. Although you could still reuse the ascent stage in this version.

1,2 tons. Not exactly that impressive for something called Falcon Heavy.

I just found this: http://spirit.as.utexas.edu/~fiso/telecon/Duggan_8-9-17/Duggan_8-9-17.pdf Everything is pretty vague but it is something.

EM-1 goes into a distant retrograde orbit. DSG is supposed to use the Near rectilinear halo orbit

Well for a reusable lander it would provide a better staging point than LLO but i agree that you probably wouldn't need a full Space station for that.

Musk Fanclub is this way

Could have. Did it happen? No. Will it happen in the 30s? I highly doubt it.

Yeah, to the Moon.

They don‘t wan‘t to build a mars ship. The DST they are proposing is launched in one piece and only refueled at the DSG. And if that works out it would be vastly better than the constellation way, Which required 5 Ares V Launches to LEO for one Mars mission. Still i think that a Mars mission is way out of reach anyway and most likely won‘t happen for another 30 years.

The idea was to send an additional stage including spare propellant for the lander alongside an Orion, meet the lander at L2, refuel it and mate it with the stage. Then you use that additional stage to translate to LLO and perform most of the Landing. An interesting concept and i think one worth reinvestigating. Especially since something like the ACES could very well fill the place of that additional stage while giving the private sector something to do. As for Altair, i guess the idea was that it could perform missions without the Orion in order to place cargo on the moon.

NRHO seems better than L2 and both are better than being stuck in LEO when it comes to exploring the moon. Edit: Boeing had a proposal for a Semi reusable lander stationed at the Exploration Gateway Platform at L2. The same concept should work at the DSG.

The only problem i have is that they already want to focus on Mars in the 30s. I‘d rather see them focusing on manned Polar or Farside Landings. I just don‘t get the whole rush to get to mars.

From all i‘ve seen, Europa Clipper should fly on Block 1b with an EUS. So it may be possible to fly both in the same year.

ESA is more of a Space Agency than Roscosmos which is has become little more than a Launch provider. Atleast ESA is actively sending robotic spacecraft around the Solar system. Also with all the Commercial Spacecraft in Development i don't see the need to develop an indigenious manned spacecraft.
