- How NASA Solved a $100 Million Problem for Five Bucks, Gizmodo - It appears you can't read digital displays when you shake at 10 - 12 Hz. When Ares I had this problem, NASA thought it would cost 100's of millions to fix it. However, a clever engineer realized that, if you strobed the display at the frequency of vibration, the screen was clear. Problem solved for $5 (or so). The bad news (?): Ares was cancelled. The good news: This technique is probably applicable to future rockets. The article includes a video demo.
- NASA Vehicle Power Interface for Hubble Space Telescope. 3 racks of equipment for only $75K on ebay. I wonder how the seller got this? Hat tip to Sascha Grant.
