Armada of Martian Probes Will Study the Planet, Inside and Out

Forty years later, the seismic study of Mars is poised for a second act with NASA’s InSight lander. As IEEE Spectrum went to press, the InSight team was still working to resolve a problem with the spacecraft’s seismometer package but aimed to keep to a scheduled March launch from Vandenberg Air Force Base, in California. If all goes as planned, the spacecraft will reach the Martian surface in September, where it will use seismometers to listen for quakes created as the planet slowly cools and contracts, vibrations rippling out from colliding meteoroids, and other sources of motion. Researchers hope to use the sound waves to build a picture of the interior of the planet, much as signals generated in a sonogram are used to image the body.
