Life Support

Here’s an interesting schematic that describes how they plan to keep crew alive to Mars and back. Doesn’t look like they’re trying to recover water from feces, but that makes sense if they’re going to use them for radiation protection. And they’re venting methane. I’d think that it would be interesting to consider it as fuel for RCS, but perhaps that’s too high a technology risk for a mission that has to leave in less than five years. I don’t see any power input to the system, but I guess that’s a separate issue.

Here’s the full briefing to FISO.

[Update a few minutes later]

OK, looking over the briefing, the current baseline seems to be two launches, one for propellant and one for crew, within a couple weeks of each other.

SLS Delenda Est

Kill it to save human spaceflight:

Simply put, the SLS program should be canceled now to free up approximately $10 billion programmed for this decade. This money could then be redirected to continue the planned flight tests of the Orion spacecraft with the much lower-cost Falcon Heavy booster while making a robust investment in a first-generation space station in the vicinity of the Moon. An investment in such a cislunar station would provide—by the early 2020s—a multifunctional platform to act as a fuel depot, a workstation for robotic operations on the Moon and a habitat to protect against the more intense radiation environment outside of the Earth’s magnetic field. This station could even be used as a habitat during longer-duration human missions to an asteroid and eventually to Mars.

Expect to see a lot more editorials like this as time goes on, new systems appear, and budgets get tighter.

KSC Fire

I just got an email that NASA personnel are being evacuated from a brush fire south of the VAB on Merritt Island.

KSC Fire 1

KSC Fire 2

“Tel-4 road runs north/south for two miles then turns west for two miles until it hits the river. So if the fire jumps that E-W stretch of highway it is off KSC property and into civilian land. There’s a pretty respectable north wind today, so it’s a bit dicey until they get that back-burn done.

The second image is looking due south. So the VAB is to my back (to the north) about 6 miles. In that image, the land to the left is KSC property, the land on the right (about where the truck is down the road) is privately held.”

Sequestration And Commercial Space

A source who (for obvious reasons) wants to remain anonymous informs me that 45th Space Wing at Patrick is starting to cut back on maintenance and operations of range safety at the Cape through the end of the (fiscal) year.

I’ll bet I could find other places to cut that wouldn’t impact commercial launches, but the administration’s goal remains to inflict the maximum amount of pain. I should note that apparently the layoffs will start in the next couple weeks. Whether or not they’ll be able to get those people back in October is an interesting question.
