NASA announced Sept. 2 that it has approved plans to launch a delayed Mars lander mission in 2018, although at an additional cost that could affect plans for later planetary missions.
The InSight Mars lander, originally scheduled for launch in March, will now launch no earlier than May 5, 2018, after NASA’s Science Mission Directorate formally approved the revised mission plan this week. That launch will allow a landing on Mars in November 2018.
NASA postponed the launch in December 2015 after a series of problems with one of its primary instruments, the Seismic Experiment for Interior Structure (SEIS), provided by the French space agency CNES. The instrument suffered a series of vacuum leaks that NASA concluded could not be fixed in time to permit a launch during a window that lasted about a month.
