Mysterious magnetic pulses discovered on Mars
The nighttime events are among initial results from the InSight lander, which also found hints that the red planet may host a global reservoir of liquid water deep below the surface.
At midnight on Mars, the red planet’s magnetic field sometimes starts to pulsate in ways that have never before been observed. The cause is currently unknown.
That’s just one of the stunning preliminary findings from NASA’s very first robotic geophysicist there, the InSight lander. Since touching down in November 2018, this spacecraft has been gathering intel to help scientists better understand our neighboring planet’s innards and evolution, such as taking the temperature of its upper crust, recording the sounds of alien quakes, and measuring the strength and direction of the planet’s magnetic field.
As revealed during a handful of presentations this week at a joint meeting of the European Planetary Science Congress and the American Astronomical Society, the
