NASA's InSight Passes Halfway to Mars

NASA's InSight spacecraft, en route to a Nov. 26 landing on Mars, passed the halfway mark on Aug. 6. All of its instruments have been tested and are working well.

As of Aug. 20, the spacecraft had covered 172 million miles (277 million kilometers) since its launch 107 days ago. In another 98 days, it will travel another 129 million miles (208 million kilometers) and touch down in Mars' Elysium Planitia region, where it will be the first mission to study the Red Planet's deep interior. InSight stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport.

This long-exposure image (24 seconds) was taken by Instrument Context Camera (ICC) of NASA's InSight Mars lander. The image shows some of the interior features of the backshell that encapsulates the spacecraft.

The backshell carries the parachute and several components used during later stages of entry, descent, and landing. Along with the heatshield, the backshell protects NASA's InSight Mars lander during its commute to and entry into the Martian atmosphere.

A global dust storm is starting to settle, but still obscures the Martian surface; the Curiosity rover turns six and drills a new rock sample; the InSight lander is more than halfway to Mars and has tested its instruments and cameras.
