NASA’s InSight lander has just felt the vibes on the Red Planet. It is the first time since the mission started; the probe has detected some vibrations. On Tuesday, NASA scientists announced that it is a marsquake. The probe is on Mars since November, it placed its seismometer (SEIS) down and initiated the innovative mission. It started listening to faint rumbles under the surface. But from December, InSight has recorded the very first quake on April 6, i.e., on 128 Martian day of the mission. It was a small quake as compared to Earth, but it plays a crucial role in the overall mission.
The discovery is a pioneer, where humans have recorded quaking that starts beneath the surface, then from something on the surface. NASA also announced that scientists are still studying InSight’s data to confirm whether it was a marsquake. Supposing the analysis concludes a quake, this would add a new milestone to the space agency’s success stories. Due to the extremely silent surface of Mars, the device was able to sense very weak shivering. Thus, NASA is not sure about the event, because it has not got any reliable information regarding the same. Still, the space agency is calling it the first probably marsquake. Scientists say three other likely seismic signals were noticed on March 14, April 10, and April 11.
According to NASA’s experts, those quakes are similar to that of Earth. They take place from the motion of tectonic plates. Scientists reveal marsquake took place due to stress created by the continual process of cooling and contraction. The pressure keeps on growing, and in the end, it becomes strong enough to break the crust, which results in a sensible quake. Although, the recording published by NASA has three different sounds. It reveals the Mars wind, the presumed quake, and the lander’s robotic arm movements. As human ears cannot detect the actual vibes, the space agency has accelerated the recording by a factor of 60. The finding has excited scientists, but it will not assist them in achieving the eventual goal of the InSight mission.
