InSight sent a second self from Mars

The American descent module InSight made a second selfie on the surface of Mars. The resulting frame allows you to see how much it has changed in recent months.

InSight was brought to the Red Planet in November 2018, and already on December 6, he took the first selfie and sent a picture to Earth. At that time, he looked like “new”, the main devices - a set of seismometers and a thermal probe to be instilled - were then still stuck to the device.

The second selfie, shown by NASA in May of this year, shows that the descent vehicle was covered with a layer of dust, and the thermal sensor and seismometer were no longer visible - InSight, using a robotic arm, moved them to the surface of a space object.

NASA told that now that these two devices have been removed, you can clearly see the white air pressure sensor. A photograph published on the Web is a mosaic consisting of 14 frames taken from March 15 to April 11, 2019.

On February 1 a dusty whirlwind raged over the landing gear, which removed a good part of the dust from the solar panels. After that, the installed pressure sensor recorded a pressure drop of 9 Pascals, which is about 13 percent of the total environmental pressure of this world. Experts note that such a serious drop in pressure has never before been detected by the equipment. In the same period, the wind speed was 72 kilometers per hour. And the wind speed record is 101 kilometers per hour.
