This week, NASA officially announced that NanoRacks will be adding an airlock onto the International Space Station to add capabilities and capacity to their already-up-and-running business.

Four members of the House of Representatives sent letters to DARPA and the Pentagon this week to file a complaint about a program in conflict with the 2010 National Space Policy.
