OSIRIS-REx Scientists: Taking Asteroid Sample was Like Punching a Ball Pit

Bennu’s surface was disturbed in three different ways: by the force of the spacecraft touching down; by the sampling mechanism, which collected material by blowing gas into its collection filter; and by four of the spacecraft’s back-away thrusters, which moved the spacecraft away from the sample site (marked with a red “X” in the second of these two images) and agitated dust and boulders on the surface. The image above shows the TAG site and highlights (red circle) a large boulder thrown about 40 feet (about 12 meters). (Credits: NASA/Goddard/University of Arizona)

TUCSON, Ariz. (University of Arizona PR) — Asteroid Bennu, the target of NASA’s OSIRIS-REx asteroid sample return mission, led by the University of Arizona, kept surprising the mission team while the spacecraft studied the asteroid from a distance. The biggest surprise, however, came when OSIRIS-REx swooped in to grab a sample of material from Bennu and encountered not a solid surface but one that gave way so easily the sampler arm sank 1 1/2 feet into it within seconds.

LUXEMBOURG, 21 June 2021 (Asteroid Foundation PR) – The Asteroid Foundation’s annual Asteroid Day LIVE programme returns in person Thursday 30 June 2022 at 11:00 CET [5 a.m. EDT/09:00 UTC]. After two years as a digital event, astronauts, experts and science communicators from across the world will again converge on Luxembourg to discuss the importance of asteroid research, missions, and advances in space-based technologies. The four-hour-long programme will vividly bring the solar system’s smallest worlds to life for audiences of all ages and backgrounds.

Asteroid Day LIVE 2022 will be built around seven panel discussions that will tell the full story of asteroids; from the formation of the Solar System, 4.6 billion years ago, to the scientific work taking place today, and our future prospects as we begin to imagine ways to utilise the resources asteroids contain.

NASA Extends Exploration for 8 Planetary Science Missions

WASHINGTON (NASA PR) — Following a thorough evaluation, NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge and understanding of the solar system and beyond.

The missions – Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Mars Science Laboratory (Curiosity rover), InSight lander, Lunar Reconnaissance Orbiter, OSIRIS-REx, and New Horizons – have been selected for continuation, assuming their spacecraft remain healthy. Most of the missions will be extended for three years; however, OSIRIS-REx will be continued for nine years in order to reach a new destination, and InSight will be continued until the end of 2022, unless the spacecraft’s electrical power allows for longer operations.

NASA Mission Helps Solve a Mystery: Why Are Some Asteroid Surfaces Rocky?

Scientists thought Bennu’s surface was like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth had suggested the presence of large swaths of fine-grained material smaller than a few centimeters called fine regolith.  But when NASA’s OSIRIS-REx mission arrived at Bennu in late 2018, the mission saw a surface covered in boulders. The mysterious lack of fine regolith became even more surprising when mission scientists observed evidence of processes potentially capable of grinding boulders into fine regolith.

WASHINGTON (NASA PR) — In a study released Wednesday, NASA researchers used precision-tracking data from the agency’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists’ ability to determine the total impact probability and predict orbits of other asteroids.

The study, titled “Ephemeris and hazard assessment for near-Earth asteroid (101955) Bennu based on OSIRIS-REx data,” was published in the journal Icarus.

GREENBELT, Md. (NASA PR) — After nearly five years in space, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu.

On Monday, May 10, at 4:23 p.m. EDT the spacecraft fired its main engines full throttle for seven minutes – its most significant maneuver since it arrived at Bennu in 2018. This burn thrust the spacecraft away from the asteroid at 600 miles per hour (nearly 1,000 kilometers per hour), setting it on a 2.5-year cruise towards Earth.

NASA’s OSIRIS-REx Completes Final Tour of Asteroid Bennu

This image shows a top-down view of asteroid Bennu, with a portion of the asteroid’s equatorial ridge and northern hemisphere illuminated. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 4, 2021, from a distance of about 186 miles (300 km). The spacecraft’s cameras are pointed directly at Bennu’s north pole. Two large equatorial craters are visible on the asteroid’s edge (center and center left). The image was obtained during the mission’s Post-TAG Operations phase, as the spacecraft slowly approached Bennu in preparation for a final observational flyby on April 7.

NASA’s OSIRIS-REx mission is on the brink of discovering the extent of the mess it made on asteroid Bennu’s surface during last fall’s sample collection event. On Apr. 7, the OSIRIS-REx spacecraft will get one last close encounter with Bennu as it performs a final flyover to capture images of the asteroid’s surface. While performing the flyover, the spacecraft will observe Bennu from a distance of about 2.3 miles (3.7 km) – the closest it’s been since the Touch-and-Go Sample Collection event on Oct. 20, 2020.
