InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the "inner space" of Mars: its crust, mantle, and core.

SpaceX will conduct an in-flight abort test of its Crew Dragon capsule. The test will ensure that Crew Dragon is capable of safely maneuvering away from the launch vehicle in the event of an anomaly. The test is part of NASA's Commercial Crew program.

OSIRIS-REx will move into position to collect a sample of asteroid Bennu's surface material. The spacecraft's sampling arm will then touch the surface for five seconds as part of the Touch-And-Go (TAG) sampling maneuver.

The OSIRIS-REx spacecraft will return a sample of the asteroid Bennu to Earth. The sample will land via parachute in the Utah desert.
