NASA is going to Mars again, this time with the first spaceship dedicated to digging deep below the surface to find out what’s shaking on the red planet.
After a six-month journey, if it all goes as planned, InSight — whose name is short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport — will touch down just north of the Martian equator on November 26, joining five other NASA spacecraft operating on and above Mars.
The 790-pound (358-kilogram) probe will then begin its two-year science mission to seek the “fingerprints” of the processes that formed the rocky planets of the solar system. It will measure the planet’s “vital signs: ‘its “pulse’ (seismology), ‘temperature’ (heat flow) and ‘reflexes’ (precision tracking),” according to NASA.
The explorer doesn’t have wheels, so it can’t roll around gathering up dirt to study. But it does have a 7.8-foot-long (2.4-meter) robotic arm. The arm will place a seismometer on the ground to detect “marsquakes” (think earthquakes, but on Mars, of course).
InSight also will burrow 10 to 16 feet into the crust of Mars, going 15 times deeper than any previous Martian mission, according to NASA.
The mission’s principal investigator, Bruce Banerdt, told CNN he thinks InSight will fill the last gaping hole in NASA’s exploration of Mars, some 75 million miles (121 kilometers) from Earth.
“We have mapped the surface of the entire planet in terms of visible features, topography, gravity and magnetic fields,” he said. “We have studied the atmosphere, both globally and at the surface. We have roved around the surface at four different places, studying the geology and piecing together the history of the surface.
“But until now, the vast regions of the planet deeper than a few miles, or so, (have) been almost completely unknown to us,” Banerdt said. “InSight will change that with a single stroke.”
