Landing the Curiosity rover on Mars was a big feat for NASA, but we could not have done it without the work of small businesses. On Wednesday, Sept. 19, NASA Administrator Charlie Bolden Joined Administrator Karen Mills of the Small Business Administration for a Google+ Hangout with ATA Engineering, one of the small businesses that made the Mars Science Laboratory mission landing a success. Administrators Bolden and Mills will talk with representatives of ATA about their work to design and analyze the design of the entry, descent and landing process -- known as "Seven Minutes of Terror" -- as well as other systems operating the Curiosity rover.
