NASA broadcasts a live event from 16:45 to 17:15 UTC to highlight the arrival of the agency's first asteroid repatriation mission. You can watch NASA TV, Facebook Live, Ustream, YouTube and NASA Live. NASA TV also broadcasts an arrival preview program from 16:15 UTC (11:15 am EST).
OSIRIS-REx (Origin, Spectral Interpretation, Resource Identification, Security Regolith Explorer) was launched in September 2016. Bennu slowly approached. OSIRIS-REx is NASA's first mission to visit an asteroid near Earth, measure its surface area, collect a sample, and bring it to Earth. The spaceship will spend almost a year measuring the asteroid, with the aim of selecting a safe and scientifically interesting location for taking the sample.
This asteroid sample is expected to return to Earth by free fall from space until it reaches a height of 33.5 km when a first parachute is deployed. At 3 km the main parachute will be released bringing the capsule with their precious cargo from Bennu for a gentle landing in the Utah desert on September 24, 2023.
