NASA will broadcast coverage of a first for the agency as its Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission attempts to collect a sample of asteroid Bennu on Tuesday, Oct. 20, at 6:12 p.m. EDT. Live coverage of the spacecraft's descent to the asteroid's surface for its "Touch-And-Go," or TAG, maneuver, which will be managed by Lockheed Martin Space near Denver, will begin at 5 p.m. on NASA Television and the agency's website. Beginning with an orbit departure maneuver around 1:50 p.m., the full sequence of the complicated engineering feat will be covered on @OSIRISREx, and media and the public can ask questions using the hashtag #ToBennuandBack. In addition to the broadcast Tuesday, Oct. 20, briefings and social media activities will cover the mission and asteroid science on Monday, Oct. 19. OSIRIS-REx, which is about the size of a 15-passenger van, is currently orbiting the asteroid Bennu 200 million miles from Earth. Bennu contains material from the early solar system and may contain the molecular precursors to life and Earth's oceans. The asteroid is about as tall as the Empire State Building and could potentially threaten Earth late in the next century, with a 1-in-2,700 chance of impacting our planet during one of its close approaches. OSIRIS-REx is now ready to take a sample of this ancient relic of our solar system and bring its stories and secrets home to Earth. + Full mission coverage and more is available here
NASA's OSIRIS-REx unlocks more secrets from Asteroid Bennu Tucson AZ (SPX) Oct 09, 2020 NASA's first asteroid sample return mission now knows much more about the material it'll be collecting in just a few weeks. In a special collection of six papers published in the journals Science and Science Advances, scientists on the OSIRIS-REx mission present new findings on asteroid Bennu's surface material, geological characteristics, and dynamic history. They also suspect that the delivered sample of Bennu may be unlike anything we have in the meteorite collection on Earth. These discoveries ... read more
