A NASA lander has detected what scientists believe to be a “marsquake.”

The Mars InSight lander registered a “faint seismic signal” on April 6, which is believed to be the first detected trembling coming from inside the planet, NASA said Tuesday in a news release

Scientists are continuing to figure out the signal’s exact cause. It sounds like a gust of wind, according to a video accompanied by the release.{mosads}

In the statement, InSight Principal Investigator Bruce Banerdt said the event has started the new field of “martian seismology.”

“InSight’s first readings carry on the science that began with NASA’s Apollo missions,” Banerdt said. “We’ve been collecting background noise up until now, but this first event officially kicks off a new field: Martian seismology!”

The likely quake was not large enough to give scientists information on Mars’s interior. Other seismic signals were registered on March 14, April 10 and April 11.

“We’ve been waiting months for a signal like this,” said Philippe Lognonné, Seismic Experiment for Interior Structure team lead at the Institut de Physique du Globe de Paris in France said in the release. “It’s so exciting to finally have proof that Mars is still seismically active. We’re looking forward to sharing detailed results once we’ve had a chance to analyze them.”
