On the shuttle they were $40 million. <br /><br />Falcon 9 and Starship are designed from the start to land and be reused. I don't think SLS could change. Remember, back when SLS started they said landing couldn't be done.

Totally my fault for not doing a good enough backup before doing the update; familiarity breeds contempt. I've setup different computers with different Linux versions since then, but haven't gone fully dual boot. <br /><br />I've heard there's an official Microsoft installation of Linux that's supposed to be easy to switch to from Windoze 10, but that's a scary combination of words. <br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-9892744122582511572021-03-18T20:13:09.558-04:002021-03-18T20:13:09.558-04:00Exactly.

The program's troubles are well documented, but if they're going to launch American astronauts on extremely public missions, I want them to be competent. <br /><br />SLS has been an example of big government, cost-plus contracting at its absolute worst. Its mission wasn't a particular space mission (after Aries program); it was to spread jobs and tax money around. Suddenly they find themselves needing to make hardware work. My ex-US representative and then ex-US Senator, Bill Nelson was a major force in getting the money spread around. Now it looks like Nelson will be nominated to be NASA administrator.<br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-47594119650940969262021-03-18T20:12:47.434-04:002021-03-18T20:12:47.434-04:00Off topic:

They're designed to dump slow highly compressed archive.org textbooks (which I find to be very slow to load and cumbersome to page through) to a pile of images. They can then rebind that pile of images into a new pdf that (while less compressed) loads pages much faster and can be flipped through.<br /><br />https://www.amssolarempire.com/Blog/?p=712<br /><br />MadRocketSciAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-43857893280581702362021-03-18T19:21:20.783-04:002021-03-18T19:21:20.783-04:00Yes, congratulations.

I've been a bit cynical about the SLS program, but this was the sort of test they need to do to develop and integrate their hardware properly. <br /><br />MadRocketSciAnonymousnoreply@blogger.com
