Conflict Of Interest?

Clark Lindsey has some thoughts on John Kavanagh’s thoughts about NASA’s potential conflict of interest in COTS/Constellation (at least as currently formulated). I might have some thoughts, too, but not today. Perhaps this weekend or next week, after I get home to Florida (where it now looks unlikely that we’ll get any severe weather soon).

On The Spot

Clark Lindsey has dropped in on the Mars Society conference, which is in DC this year, and has some first-hand reports, on Mike Griffin’s speech and the latest from Elon Musk and SpaceX.

I haven’t spent much time reading them myself, being too busy, but when I do later, I may have some thoughts.

One question I do have, though. Just how big does Mike think is big enough for a heavy lifter for a Mars mission? How many decades does he plan to put off developing the critical technologies of orbital storage and handling of propellants, and vehicle assembly?

Nuts and Bolts of SpaceX Process

SpaceX has moved to “version 1.1” which expresses Elon Musk’s confidence that the next launch will not have the same problems as the first. (In software culture, which Musk earned one of his fortunes in, an initial version of 0.9 or no version augmentation from previous expresses scepticism. 1.1 or augmentation of the major or minor version expresses confidence.) To fix the specific failure from the last launch “…any exposed aluminum B-nuts are being replaced with either an orbital welded joint or a stainless steel B-nut that won’t corrode.” To fix many other sources of potential failure, the electronic monitoring, automatic launch procedures, remote monitoring, exterior redesign and better climate control for payload are all excellent improvements. Bravo!

The oversight by managers they implemented needs more details released before I would recognize it as a new improved way of doing business. (Finally, while I have seen another company launch with the engine compartment on fire, a technical coup may be a PR mistake.)

In other news, Musk’s electric car company is making headlines.

Bummer

A Dneper rocket carrying a lot of Cubesat university experiments failed to get them to orbit. I’m glad that wasn’t Bigelow’s Genesis 1 flight, though.

And it demonstrates once again that no one currently builds reliable launch systems. It also shows the continuing folly of using (in this case literally) converted munitions as transportation devices. Until we fix the problem of reliability and affordability (issues that NASA’s plans don’t even attempt to address), it’s pointless to plan lunar or Mars missions.
