We heard our first marstrasse

After landing on Mars in November last year, the probe InSight first launched a set of meteorological equipment, and then began to check the health of its scientific instruments. After that, the lander NASA launched its assembled French seismometer on the surface of the red planet in December, and brought it into operation in early February. And started to listen.

Finally, on 6 April, the seismometer recorded a weak, but significant seismic signal. The researchers concluded that the boost from the earth that it came from the bowels of the world, not due to any external factors like wind.

The first sounds of the Martian earthquake

“We’ve been waiting months for our first marsotryaseniya,” says Philip Lanion, principal investigator of the mission of the seismometer, which was developed by the French space Agency CNES. “It’s great to finally get the evidence that Mars is still seismically active. We look forward to the opportunity to share detailed results as soon as I read them and simulate our data”.

Of course, scientists have studied earthquakes on our own planet more than a hundred years, listening to them and measuring. In 1969, astronauts Neil Armstrong and buzz Aldrin deployed a seismometer on the moon almost 50 years ago to explore the internal structure of the moon. And found incredibly active geological world.

French scientists in conjunction with NASA has detected that marsotryaseniya reminiscent of those that occurred on the moon.

“The first InSight continue reading science, which began with the mission “Apollo”, says Bruce Banerdt, InSight principal investigator from the jet propulsion Laboratory of NASA in Pasadena, California. “Until now, we collected background noise, but this is the first event officially opens a new field: the Martian seismology”.

This earthquake was not strong enough to tell much about the internal parts of Mars, but they expect that future, stronger earthquakes provide this information.

Meanwhile, NASA and its international partners continue to troubleshoot the probe, “the mole” โ€” part of the descent module, designed for backfilling to a depth up to five meters and providing additional information about the surface of Mars. Shortly after the mole began to hammer itself into the surface two months ago, his progress has been stopped and scientists are now exploring, stuck or not.
