NASA is calling off the launch of a mission to Mars because of a series of leaks in a key instrument meant to tell scientists about earthquakes and seismic activity on the red planet.
The InSight, known fully as the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport mission, is a collaboration between NASA, other agencies such as France's National Center for Space Studies, and contractors such as Lockheed Martin.
Its purpose is to study the deep interior of Mars, including the planet's seismic activity. Data from such a mission could tell researchers a great deal about the formation of rocky planets, including Earth. And it is important to understand seismic activity if NASA wants to reach its goal of putting humans on Mars.
