NASA’s InSight spacecraft

NASA’s Mars Lander InSight has recorded its first ‘Marsquake.’ It has recorded a quake of 2 or 2.5 magnitude which is hard to predict on Earth’s surface.

About InSight Mission:

InSight is part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama.

It will be the first mission to peer deep beneath the Martian surface, studying the planet’s interior by measuring its heat output and listening for marsquakes, which are seismic events similar to earthquakes on Earth.

It will use the seismic waves generated by marsquakes to develop a map of the planet’s deep interior.

Zero Shadow Day

A sub-solar point is when the sun is directly overhead at a particular latitude. When the sun is at the zenith (the highest point in the sky) its rays will be hitting a particular point exactly perpendicular to the surface.

This will make your shadow be exactly under you, making it look like there are no shadows. Take a small jump and you can see your shadow.

How often does it happen? It occurs twice a year.

To know where exactly it is happening now and when it will happen next you can download the Zero Shadow Day app from the Astronomical Society of India.
