Topic: OSIRIS-REx
During its October 20th, 2020, sample collection event, the spacecraft collected a substantial amount of material from Bennu’s surface, likely exceeding the mission’s requirement of 2 ounces (60 grams). ![]() This illustration shows the OSIRIS-REx spacecraft departing asteroid Bennu to begin its two-year journey back to Earth.

NASA’s OSIRIS-REx Spacecraft retrieves good amount of material from Asteroid Bennu
The spacecraft captured images of the sample collector head as it moved through several different positions. In reviewing these images, the OSIRIS-REx team noticed both that the head appeared to be full of asteroid particles, and that some of these particles appeared to be escaping slowly from the sample collector, called the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) head. ![]() Captured by the spacecraft’s SamCam camera on Oct. 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. They show also that some of these particles are slowly escaping the sampler head. Analysis by the OSIRIS-REx team suggests that bits of material are passing through small gaps where the head’s mylar flap is slightly wedged open.

NASA’s OSIRIS-REx spacecraft touches down, takes Sample from Surface of Asteroid Bennu
The sampling event brought the spacecraft all the way down to sample site Nightingale, touching down within three feet (one meter) of the targeted location. ![]() Captured on October 20th during the OSIRIS-REx mission’s Touch-And-Go (TAG) sample collection event, this series of 2 images shows the SamCam imager’s field of view at the moment before and after the NASA spacecraft touched down on asteroid Bennu’s surface.

NASA releases Broadcast times for OSIRIS-REx Asteroid Sample Collection Activities
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 4:00pm CT on NASA Television and the agency’s website. ![]() NASA’s OSIRIS-REx mission readies itself to touch the surface of asteroid Bennu.

NASA OSIRIS-REx Spacecraft prepares for Touch-And-Go mission to asteroid Bennu
On October 20th, 2020 the mission will perform the first attempt of its Touch-And-Go (TAG) sample collection event. This series of maneuvers will bring the spacecraft down to site Nightingale, a rocky area 52 ft (16 m) in diameter in Bennu’s northern hemisphere, where the spacecraft’s robotic sampling arm will attempt to collect a sample. ![]() This artist’s concept shows NASA’s OSIRIS-REx spacecraft descending towards asteroid Bennu to collect a sample of the asteroid’s surface.

NASA investigates why Asteroid Bennu is shedding material into Space
Now, after more than a year and a half up close with Bennu, they’re starting to better understand these dynamic particle-ejection events. ![]() This mosaic image of asteroid Bennu is composed of 12 images collected on Dec. 2, 2018, by the OSIRIS-REx spacecraft’s PolyCam instrument from a range of 15 miles (24 kilometers).

NASA’s OSIRIS-REx spacecraft completes Second Rehearsal, Ready to make Sample Collection
The approximately four-hour “Matchpoint” rehearsal took the spacecraft through the first three of the sampling sequence’s four maneuvers: the orbit departure burn, the “Checkpoint” burn and the Matchpoint burn. «Read the rest of this article» Sections: Technology | No Comments
NASA’s OSIRIS-REx spacecraft to rehearse landing on Asteroid Bennu
In order to achieve this challenging feat, the OSIRIS-REx mission team devised new techniques to operate in asteroid Bennu’s microgravity environment – but they still need experience flying the spacecraft in close proximity to the asteroid in order to test them. So, before touching down at sample site Nightingale this summer, OSIRIS-REx will first rehearse the activities leading up to the event. ![]() This artist’s concept shows the trajectory and configuration of NASA’s OSIRIS-REx spacecraft during Checkpoint rehearsal, which is the first time the mission will practice the initial steps for collecting a sample from asteroid Bennu.
