Space.com: The US’s next low-budget planetary mission—called InSight, short for interior exploration using seismic investigations, geodesy, and heat transport—is scheduled to launch in 2016. The 12th in NASA’s Discovery-class missions, the probe will study the interior and structure of Mars in order to shed light on the evolutionary processes of all the rocky planets in the solar system. At the relatively modest cost of $425 million, the project follows in the wake of NASA’s pulling out of the European-led ExoMars mission because of federal budget cuts.
