That went perfectly.

The landing of the ITS "spaceship" really seems like a modernized version of older sci-fi illustrations. Elon Musk intends to use a crane (I'm guessing an internal system) for disemarking and reembarking on Mars. Elon Musk on Twitter: "@BArtusio Three cable elevator on a crane. Wind force on...

The difference being more about delta-t than delta-v.

I thought VASIMR required some ridiculous power source (on the order of a couple hundred megawatts, while ISS only produces tens of kilowatts - such a nuclear reactor would be too heavy or require unrealistic materials)

Liquid hydrogen tends to boil off, and any systems to mitigate that for the several-month journey to Mars were considered to be too heavy, expensive, or complex (this also applied to ground handling systems). Liquid methane and LOX are close in temperature, so it's easier to handle. You also...

"tight resources" - SpaceX wants to do space access more efficiently. (I see your point there, N_Molson, but they don't plan to send millions of people with kerolox Falcon 9s)

I was only stating that as a possible outcome, but there are some people on spaceflight forums who deeply believe manned missions to and colonization of other planets is a waste of time and money. "Oh, sending robots is cheaper and much more effective for what was invested," they might say. Or...

Exactly. That's why I love Musk's determination to colonize Mars. The cost per person for going to Mars is dependent on how many people are going, because of economies of scale. The real question is, are there enough people who are willing to go so that costs can be brought down so that enough...

Just read through this thread on the KSP forum, there's a mixture of excitement and skepticism (e.g. claims that there will be no return on investment) as well. I don't want to come off as negative, I am only unsure. I prefer to live in a future where there is massive activity in space...

Reminds me of your parody post from 2013. Again, I have mixed, contradictory feelings about all this. I am skeptical because I am not sure if millions of people want to pay to permanently move to a barren red desert that's worse than any place on Earth even after some disaster. (There's...

It's great, because it means that my fictional rocket after M-III can have 39 engines.

My thoughts about the presentation: - I expected the integrated second stage + transfer vehicle to be a cylindrical lifting body (because it presents a larger surface area than a capsule shape during aerocapture into Mars's thin atmosphere). - Need to improve cost for a trip to Mars by...

This is everything I thought it was going to be. (mostly)

Raptor engine test - this is what large scale methalox engine exhaust looks like: Elon Musk on Twitter: "Mach diamonds https://t.co/TCX7ZGFnN0"

Here is my recreation of the mission profile in Kerbal Space Program (with the Real Solar System and Realism Overhaul mods).

Elon recently tweeted: Elon Musk on Twitter: "Turns out MCT can go well beyond Mars, so will need a new name... Also, there might be a name for the booster stage... Elon Musk on Twitter: "@andyzalk sounds like the right name for the rocket booster" Don't forget, the announcement of the Mars...

Just like my fictional M-III. Methane engines, too. I was expecting a Falcon 9 sized rocket, but I'm guessing Blue Origin wants to have a heavy-lift rocket like SpaceX's next-generation reusable heavy-lift Mars rocket codenamed "BFR" (which is supposed to be revealed later this month)...

I'm finally getting into Gundam now.

I just finished watching Planetes, great series.
