Lander will be tracked by mini satellites before it begins probing red planet’s ‘inner space’
The lander will dig deeper into Mars than ever before — nearly 16 feet, or five metres — to take the planet’s temperature. It will also attempt to make the first measurements of marsquakes, using a seismometer placed directly on the Martian surface.
A special transmitter on the lander will send radio signals back to Earth, tracking Mars’ subtle rotational wobble to reveal the size of the planet’s core and possibly whether it remains molten.
The Atlas V (five) rocket also holds a pair of mini satellites meant to trail InSight all the way to Mars in a first-of-its-kind technology demonstration.
