It always comes in slightly to the side of the barge and as part of the landing burn it does a final sideways correction. I believe it was for this kind of situation - or one where…

Didn't google earth have exactly this in the early days? I can't remember exact details, but pretty sure it was an easter egg - ctrl + alt + a would launch it.

Also reminds me of ethernet over barbed wire. Seems like similar things have been done for a long time... http://www.sigcon.com/Pubs/edn/SoGoodBarbedWire.htm

Pretty sure Wernher von Braun isn't available any more though [x], in fact I think you're going to have a real hard time with many of the other principals. Principles though seem t…

I believe that comment is more or less based on the shuttle landing and/or the soyuz capsules (eg parachutes) - but as far as I can tell, SpaceX is the only one currently capable (…

How often do sysadmins actually make the call on what gets bought? For a purchasing dept, they'd probably stop at step 2, get the over-priced product and everyone's happy. The re-s…

There's a relationship management issue there somewhere - supporting one-off small volume sales has a definite cost at some point - someone needs to process and fill the order. Lim…
