The SEIS (Seismic Experiment for Interior Structure) instrument on NASA’s InSight lander has sensed 21 Marsquakes since it was deployed on December 19th, 2018. It actually sensed over 100 events to date, but only 21 of them have been identified as Marsquakes. SEIS is extremely sensitive so mission scientists expected these results.Continue reading “InSight Has Already Detected 21 Marsquakes”
NASA managers have just made the difficult but unavoidable decision to scrub the planned March 2016 launch of the InSight lander, the agency’s next mission to Mars, by at least two years because of a vacuum leak that was just detected in the probes flawed seismometer instrument which cannot be fixed in time.
The leak, if uncorrected, would render the probe useless to carry out the unprecedented scientific research foreseen to measure the planets seismic activity and sense for “Marsquakes” to determine the nature of the Red Planets’ deep interior.
