A new NASA land use agreement is bringing Google — and, ultimately, the general public — one step closer to outer space. Google announced a 40-year plan Thursday to build a massive research and development campus within NASA’s Ames Research Center. Google will pay $3.66 million a year for the 42.2 acre as-yet-undeveloped lot in Mountain View, Calif. Construction is slated to start by 2013 and go all the way through 2022. Google’s deal with NASA marks a major turning point in the organizations’ unusual public and private sector partnership.
