InSight, which stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, will launch aboard a United Launch Alliance Atlas V rocket. InSight will study the deep interior of Mars to learn how all rocky planets formed, including Earth and its Moon. The lander's instruments include a seismometer to detect marsquakes, and a probe that will monitor the flow of heat from the planet's interior.
The Atlas V rocket will carry the spacecraft over the Channel Islands just off the California Coast and continue climbing out over the Pacific. The rocket will reach orbit about 13 minutes after launch, when the rocket is about 1,200 miles (1,900 kilometers) northwest of Isabella Island, Ecuador.
Getting a Mars mission flying requires a great many milestones. Among those still to come are the official start of the countdown to launch -- which comes on Saturday at 1:14 a.m. EDT. A little over an hour later, at about 2:30 a.m. EDT, the 260-foot-tall (80-meter) Mobile Service Tower -- a structure that has been protecting the Atlas V launch vehicle and its InSight payload during their vertical assembly -- will begin a 20-minute long, 250-foot (about 80-meter) roll away from the Atlas.
InSight's landing on Mars is planned for Nov. 26, around 3 p.m. EST.
The Jet Propulsion Laboratory (JPL) in Pasadena, Calif., manages InSight for NASA's Science Mission Directorate. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Ala. The InSight spacecraft, including cruise stage and lander, was built and tested by Lockheed Martin Space in Denver, Colo. NASA's Launch Services Program at the agency's Kennedy Space Center in Florida provides launch management. United Launch Alliance of Centennial, Colo., is NASA's launch service provider of the Atlas V rocket. A number of European partners, including France's Centre National d'Études Spatiales (CNES) and the German Aerospace Center (DLR), are supporting the InSight mission. In particular, CNES provided the Seismic Experiment for Interior Structure instrument, with significant contributions from the Max Planck Institute for Solar Systems Research. DLR provided the Heat Flow and Physical Properties Package instrument.
