Mars And SLS

I really find Chris Carberry’s op-ed on SLS incomprehensible. Oh, I don’t mean I don’t understand it, it just seems disconnected with reality, and the interests of anyone seriously interested in seeing humans go to Mars. He speaks about SLS as thought it has kind of reality, and actual utility. To me, a sane Mars organization would be screaming bloody murder at the waste of money to the detriment of hardware needed to actually get to Mars.

Thoughts on the ever-receding SLS, from Bob Zimmerman.

Falcon Heavy And Asteroid Mining

Martin Elvis says it’s a game changer. BFR would be even more so. But this (from the story’s author) is a little silly:

Also, I feel like launching all of those rockets and processing the metals can’t be good for the environment.

The metals would be processed in space. The whole point of this is to start to move industry off the planet, which would be great for the environment. He should try thinking, and doing some actually analysis, rather than going on feels.

[Tuesday-morning update]

This seems related, sort of: Planetary Resources has a funding shortfall.

Seems like those billionaires who supposedly founded it don’t actually have that much faith in the venture.

Lunar Science Workshop

Light posting because I decided at the last minute to fly up to San Jose for the workshop at NASA Ames. Been listening to lunar stuff all day. Highlight: a talk by Jack Schmitt, the only geologist to walk on the moon, and the second to last to walk on it, a little over 45 years ago. And with the death of John Young a few days ago, only one of five remaining moon walkers. He’s looking pretty good at 82, and I think he stands a good chance of seeing the next person walk on the moon.

The Webb Telescope

We had dinner with Leonard and Barbara David when we were in Colorado over the holidays. He told me that he’d been working on this piece about whether it’s too big to fail.

I’ve been concerned about the risk for years. I hope it works, but it’s not the approach I’d have taken. The next big telescope will be assembled in space, not launch origami.
