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”
Just two weeks ago, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander touched down on the surface of Mars. In the hours that followed, mission controllers at NASA-JPL received confirmation that the lander had deployed its solar arrays and was commencing scientific operations.
And in what was sure to be a treat for space exploration enthusiasts, the lander recently provided the first ever experience of what it “sounds” like to be on Mars. The sounds were caught by an air pressure sensor inside the lander and the seismometer instrument that is awaiting deployment to the surface. Together, they recorded the low rumble caused by Martian winds that blew around the lander’s location on Dec. 1st.
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.
