Space Jobs

Donald Robertson has a crazy idea: Find something useful for people working SLS/Orion to do:

Presidents answer to the nation, not to local job concerns. Two presidents in a row — Bush and Obama — have tried in varying degrees to redirect NASA away from the Apollo model, only to be blocked by institutions and senators who are answerable to local NASA employees. This time, we cannot repeat Mr. Obama’s mistake of canceling the SLS without finding a future for the people who work on it.

The new “constellation” work needs to be planned and distributed in a way that will keep the traditional NASA workforce, and those who represent them, on board. Where is it written that engineers in Alabama cannot be employed building space-based tugs and modules for a lunar base? To have any chance of killing the SLS and replacing it with a useful space program, opponents need to come up with something that fulfills SLS’s political and economic purpose at least as well, while endeavoring to achieve something useful in space at the same time. That is beginning to occur, as NewSpace companies like SpaceX slowly expand beyond California and the Seattle area and increasingly employ people in Texas, Florida, and other traditional NASA states.

Encouraging this change will take a great deal of political capital and skill —the Bush administration did not deploy the former, and the Obama administration failed at the latter. So far, the Trump administration has shown little aptitude for any kind of positive relationship with Congress.

If someone does not come forward to invest the political and financial capital needed to end this conflict and move on to a more constructive vision, the United States will continue to drift in space. Resources will remain split between an increasingly successful but underfunded NewSpace industry unable to fulfill its potential, and the SLS and Orion, which the nation cannot afford to actually use. Our future in space will increasingly rely on largely self-funded efforts by people like Elon Musk and Jeff Bezos.

He says that like it’s a bad thing.

Meanwhile, NASA has incorporated its next planned boondoggle into human exploration plans.

A Veneer Of Certainty

How dependable is climate science?

Not enough to base energy policy on.

[Update a few minutes later]

A vigorous fisking of what Judith Curry calls “the stupidest [peer-reviewed] paper ever written.” With all respect to Professor Curry, that’s a pretty high bar, even in this field.

[Update a couple minutes later]

OK, I slightly misquoted her.

[Update a while later]

Link is fixed, sorry!

GIMP (Again)

Is there a doctor in the house? I’m trying to paste a transparent layer in, and all I’m seeing is an outline of it. Anchoring it does nothing. This may be related: It pastes into the canvas in the upper left corner, but that isn’t part of the image I’m trying to put in into, and I don’t know how to get rid of the dead space above. This is the most infuriatingly non-obvious user interface I’ve ever seen.

[Update a couple minutes later]

OK, I got rid of the extra canvas, but I still see nothing when I paste the new layer in.

[Update a while later]

OK, finally figured it out. I had to “Select All” before copying.

The Russian Space Program

Its woes continue, with another Soyuz launch failure, because the Fregat fired in the wrong direction. Now probably Atlantic-stationary orbit.

Here’s the story from Doug Messier.

[Afternoon update]

Meanwhile, back in the USA, NASA (and the ASAP) is still stupidly obsessing over safety.

This is nuts. Soyuz capsules aren’t armored to that MMOD requirement. As I just emailed a high-level NASA official, why don’t we just quit flying?

The SLS Mess

Jason Davis has a good rundown on it, and the implications for Europa Clipper. I don’t know how he knows this, though:

Any other rocket besides SLS—including SpaceX’s upcoming Falcon Heavy—lacks the power to blast Clipper directly from Earth to Jupiter. A conventional rocket would rely on three gravity assists from Earth and one from Venus, increasing the transit time from about 2.7 years to 7.5 years.

How does he know that? Has he run the numbers, or is he just taking NASA’s word for it? He’s also not considering the possibility of New Glenn, New Armstrong, Vulcan/ACES with a distributed launch, or BFR, all of which could be ready by 2022.

Android And SCP

So I’m trying to move some files from my Linux desktop to my tablet. I suppose the easiest way to do it would be via USB, but it would be nice if I could do a file transfer over the wireless network. I set up the Android with a linux shell, and I’m able to ssh into my desktop with it. But when I use the Android app “andFTP,” which everyone seems to praise, to scp files, it won’t authenticate. Anyone have any idea what the issue could be?
