This is pretty sexy. Not so sure about traveling at 62k mph but who knows.

Canned man. I'll. Pass. We are already on the best spaceship we will ever have. Spaceship Earth.

Runs on solar. Too big for RCS thrusters. All the filters in the life support system are clogging up. Half the crew are pyromaniacs and the other half are nymphomaniacs.

Even Carl Sagan would say "f**k this" and go down t the shore to build a nice boat for that ocean of night. This island is hosed.

Having had a chance to watch Musk's entire presentation, I'm a bit disappointed, honestly. The decision to go with methane engines is solid, despite the challenges. The idea of taking the fuel down to such a low temperature that the density increases to the point of negating cavitation issues along the leading edges of the turbopump impeller blades is frankly brilliant. Even the kerosene engines are going to develop serious impeller damage over repeated uses. And full-flow staged combustion is f**k hard. Both fuel and oxidizer are to be completely phased over to gas before they hit the chamber. Its a seriously challenging engine. And they want to run 42 of them simultaneously.

All that said...the basic challenges haven't changed, the funding problems have not changed, and fantastical images of one of these vehicles sitting on Europa or Enceladus isn't going to create the realistic 2020 timeframe he was talking about. I have no doubt of the technical capability, assuming we've all got the will to stomach the loss of human life that always accompanies the colonization of distant shores, to make this happen. I doubt the money will be there. And I saw no time spent on the necessary infrastructure to maintain a human population over there. It would take centuries, in all probability, to create an economically and materially self-sufficient Martian population. Musk is mostly focused on the spacecraft. Which is fine...but its only a small piece of the puzzle if the overaching ideology of his company (and his personal passion and life goal) is to make humanity multi-planetary.

anyway, /rant, but the presentation was solid.

Till we get warp speed, our cosmic empire =low earth orbit, the moon, and maybe mars.

it only took 9 years to get to pluto. im confident we will have mining operations in the kuniper belt within 100 years, with or without bending space-time

we're on the cusp. elon musk wants to push us over the edge. he's an arrogant asshole but if he gets us to mars his name will be remembered for millennia to come. looking back in history, columbus sailed the ocean blue in 1492. for the next hundred years history mainly has failed attempts of colonization, and most colonies were in mesoamerica. but once one finally took hold in the north, it created an explosion of people moving from europe in search of terra nova. once it's shown it can be done, it will be done many times over

Very true. There just needs to be some sort of economic case for it. There will be dreamers who want to be the tip of the sword, sure. But mostly people are out to enrich themselves in some way. It takes a special sort to give up the warm spring afternoons under a tree with a cold beer and a BBQ beef rib on Earth, for a cold dirt cave on Mars, slurping cardboard flavored protein paste and working your ass off in an environment that wants to kill you for the rest of your days. The early pioneers, as they always have, will need to be hardy gluttons for punishment with things to prove.

As for travel time, once we get the low thrust, high specific-impulse plasma rockets working on a large scale, we could have relatively short travel times, at least around the inner system. Something like VSIMR, only with a nuclear reactor behind it, could be a complete game changer. The tech already exists.

My predictions is tourism in low earth orbit, and restricted to the mega wealthy.

I think there will eventually be a one-way launch option for those on a more regulated income. Start saving now.

musk's plan is a few hundred thousand dollars for a ticket, and it's one way. sell all your shit, get some loans (somehow, likely by lying) and you're off
