LINCOLN OSIRIS FULL
22, 2020, this series of three images shows that the sampler head on NASA’s OSIRIS-REx spacecraft is full of rocks and dust collected from the surface of the asteroid Bennu. Days later, it became clear that the collection attempt had been so successful that the sampling head was overflowing.Ĭaptured by the spacecraft’s SamCam camera on Oct. Based on the regolith characteristics the team observed in images from the spacecraft, those pads are likely to have collected additional material. of material has been mobilized, giving us additional confidence that we actually pushed material up into the sampler head.”Īdditionally, the team was optimistic because the sampler head, known as the TAGSAM, is fitted with pads of stainless-steel hook and loop fasteners. “It’s the kind of mess we were hoping for. We really did kind of make a mess on the surface of this asteroid, but it’s a good mess,” Lauretta said. “When the gas bottle gets fired, you can see that particles are flying all over the place. on October 21, the team received the image sequence that showed the contact and collection. “We were watching the images come down one by one…” At about 2 a.m. “I can tell you a lot of us were up really late last night,” said Dante Lauretta, OSIRIS-REx principal investigator, speaking at a NASA press conference the following afternoon. Because it takes the data streaming from the spacecraft more than 18 minutes to reach Earth, and there were large amounts of data to transmit, it wasn’t immediately apparent if the early evening collection attempt had been successful. Those six seconds were all that the team expected, and enough for the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) sampling head mounted at the end of the arm to crush regolith on the surface and disperse a burst of compressed nitrogen, which further loosened regolith and drove it up into collection chambers within the TAGSAM.Īt such a great distance from Earth, the spacecraft performed the maneuver autonomously, based on programming that was sent by the OSIRIS-REx team following painstaking site identification and practice sessions at the asteroid, Bennu. On October 20, 2020, the OSIRIS-REx spacecraft descended toward the surface of the small asteroid it was orbiting 200 million miles from Earth and touched the rough surface with a sampling arm for six seconds. In space exploration, decades of research and development often come down to a matter of seconds. Sample could provide important clues about the early solar system, seeds of life.
