NASA Looks a Decade Ahead in Planning Its Mars Missions

The two exploratory vehicles currently roaming the surface of Mars are sending back data that have been “incredibly revealing,” National Aeronautics and Space Administration (NASA) Associate Administrator Edward Weiler told the Senate Space subcommittee March 10.
Weiler added that the agency has plans for missions to Mars every two years into the next decade on a launch schedule that takes advantage of the optimal alignment between Mars and Earth that occurs every 26 months.
