Watch a NASA Spacecraft Touch Down On an Asteroid to Collect a Sample

posted by Jason Kottke   Oct 22, 2020

On Tuesday, NASA’s OSIRIS-REx spacecraft touched down on an asteroid called Bennu for about six seconds in order to collect a mineral sample to bring back to Earth.

The Origins Spectral Interpretation Resource Identification Security - Regolith Explorer spacecraft will travel to a near-Earth asteroid, called Bennu (formerly 1999 RQ36), and bring at least a 2.1-ounce sample back to Earth for study. The mission will help scientists investigate how planets formed and how life began, as well as improve our understanding of asteroids that could impact Earth.

The video above is a time lapse sequence of the touch down, sampling, and subsequent take off.

These images were captured over approximately a five-minute period. The imaging sequence begins at about 82 feet (25 meters) above the surface, and runs through the back-away maneuver, with the last image in the sequence taken at approximately 43 feet (13 meters) in altitude — about 35 seconds after backing away. The sequence was created using 82 SamCam images, with 1.25 seconds between frames.
