The Space Launch System

A history. I’d dispute this, though:

“Humans are pretty needy,” Lyles told me. “You’re taking water, you’re taking all of their environmental control systems, and whatever they need on a really long mission. A large, heavy launch vehicle is almost a no-brainer.”

NASA is not alone in this conclusion. During a two-week span last month, private companies SpaceX and Blue Origin both unveiled giant, SLS-scale launchers that will become key parts of their future spaceflight aspirations.

One of these things is not like the others. SpaceX and Blue Origin want to build big rockets because they plan to put thousands of people into space. NASA is doing it because Congress wants to keep thousands employed in the right zip codes (as the article makes clear).

SpaceX’s Announcement

Here’s Nadia Drake’s story on the announcement. The Q and A ended up being sort of a goat rodeo.

Thoughts from Bob Zubrin.

Joel Achenbach says don’t pack your bags for Mars yet. And Ken Chang says Elon just needs to figure out how to pay for it. Well, I think there are other issues as well. Meanwhile, the National Space Society is gung ho (as they should be, it’s much more in line with the group’s stated objective than anything NASA is doing).

McCandless link was missing, but I fixed it.

In response to Dreier:

Here’s Alan Boyle’s take.

And Elon answered yesterday’s question about how they get down to the surface:

Bill Nye doesn’t buy it. But the Planetary Society doesn’t want “filthy meatbag bodies” on Mars, anyway.

Speaking of which, I’m pretty sure that this announcement will re-energize the SJWs.

An amusing take over at Wait But Why. And one of the first, but certainly not last takes on planetary protection and the Outer Space Treaty.
