I found more space things the day right after the last space-themed tech Tuesday.

Nice to see it coming along. Space related because A) I said so and B) space brings all kinds of new fun ways to get broken.
And last but not least; Railguns. The Navy has officially announced it's going to be putting a railgun on a ship by 2016. http://www.navy.mil/submit/display.asp?story_id=80055 Railguns were the talk of every future weapon show on the planet until about 5 years ago, when suddenly railguns just fell off the face of the planet. I took this as a sign that progress was being made. I was right. Reportedly, it can shoot a spike at Mach 7, and punch through 6" of steel armor plate. I can definitely see railguns as being a space-gun of choice, because explosives in orbit seem like a bad idea. Also, take up way more space and weight. Now I just want a man portable one that you feed ammo out of a big nail-gun roll.
