NASA demonstrates that nanotube memory chips--NRAMS--are impervious to the extreme environment and lethal hazards of space during a recent shuttle mission. Lockheed Martin and NASA reported this month that they successfully tested Nantero's nanotube-based memory chips on the Space Shuttle Atlantis while it serviced the Hubble Space Telescope earlier this year. Nanotube memory chips--NRAMs--store information by virtue of tiny mechanical switches that are immune to the heat, cold, cosmic rays, hard radiation and every other hazard from which conventional semiconductors must be protected in space, according to their inventors, Nantero.
