NASA To Cryogenically Freeze Satellite Mirrors 47

Posted by Soulskill

coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

There are a lot of ways to make your point on the internet, and one of them is to not talk about shit you don't know. It's Ad hominem. And yes,seriously, that's a wiki link. If you would deign to look at it you might learn something, like the fact that dakameleon didn't commit an ad hominem. Saying India won't develop nuclear weapons when they already have makes you look like an idiot, and I thought dakameleon let you off lightly.

The Broken Design of Microsoft's "Fix it" Tool 165

$luggo writes "Curious about MS Fix It, I recently went hunting in the MS knowledge base for articles that provide the new EZ-button. After locating on few, I decided to click the button to download the Microsoft Installer package containing the executable and/or files that automatically enable the DVD Library feature in Windows Vista Home Premium and Ultimate — on my XP Media Center. 'Surely, MS will use some scripting, HTTP User-Agent sniffing, or even Genuine Windows validation to verify that I am running Vista,' I thought. It did not and I canceled the download when I received the prompt to save the file. So, I wonder: is there a Fix-it for Fix it? Because I can easily imagine someone doing what I did without scrolling to the bottom of the KB article and verifying that the article applies to their OS/version. This is a great example poor design. Why not simply use the download approach that other articles / fixes / service packs use, whereby the user must select the appropriate OS?"
