NASA sets new robotic mission to Mars for at least two years
NASA announced Tuesday that the InSight Mars mission delays due to a leak in a seismological measuring instrument. The problem is not to solve for the planned mission launched in March 2016.
The InSight mission aims to study the internal structure of Mars. The problem with the Seismic Experiment for Interior Structure of SEIS consists of a leak in the vacuum housing. The instrument is provided by the French space center CNES and can move into the ground to measure the size of the diameter of an atom. The instrument is protected against the harsh conditions on Mars by a vacuum enclosure. The leak was previously discovered and seemed repaired. Unfortunately, in testing last week at temperatures down to -45 degrees Celsius that the vacuum again not kept.
NASA to this leak should the mission for more than two years delay, because Earth and Mars together only between May and June 2018 again come so close that the moment is appropriate to launch. This proximity will point every 26 months. The trip to Mars takes about six months.
