OSIRIS-REx Stow Success Media Telecon

Released on October 29, 2020

NASA hosted a media teleconference at 4 p.m. EDT Thursday, Oct. 29, to provide an update on the status of the agency’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft and the mission’s work to safely stow the sample it collected from asteroid Bennu.

The OSIRIS-REx spacecraft made a dramatic six-second touch of Bennu on Oct. 20, and video released the next day indicated a significant number of particles were agitated on Bennu’s surface and collected in the spacecraft’s Touch-And-Go Sample Acquisition Mechanism collector head. Over the following days, the team worked ahead of schedule to stow the primordial cargo for return to Earth in September 2023.

During the teleconference, OSIRIS-REx team members discussed how the stowage process had gone, what else they had learned about the sample, and what the next steps are for the mission to return the sample to Earth.

1. Freund - Sample Stow Animation

This animation shows the initial steps of the OSIRIS-REx spacecraft’s procedure for stowing the sample. The sequence begins with opening the Sample Return Capsule (SRC) and goes through placing the collector head onto the capture ring.

2. Freund - StowCam Stow

Taken on Oct. 27, this imaging sequence shows NASA’s OSIRIS-REx spacecraft successfully placing its sample collector head into the Sample Return Capsule (SRC). The sequence begins with the collector head hovering over the SRC after the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) arm and moving it into the proper position for capture. At the end of the sequence, the collector head is secured onto the capture ring in the SRC. A few particles can also be seen escaping from the capsule.

The image sequence was captured by the StowCam camera. StowCam, a color imager, is one of three cameras comprising TAGCAMS (the Touch-and-Go Camera System), which is part of OSIRIS-REx’s guidance, navigation, and control system. TAGCAMS was designed, built and tested by Malin Space Science Systems; Lockheed Martin integrated TAGCAMS to the OSIRIS-REx spacecraft and operates TAGCAMS.

3. Freund - StowCam Pull Test

Captured on Oct. 28, this image sequence shows NASA’s OSIRIS-REx spacecraft performing the “backout check.” This maneuver commanded the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) arm to back out of the capsule, and is designed to tug on the collector head. The backout check confirmed that the latches which keep the collector head in place are well secured.

4. Freund - Stow TAGSAM Detached

Taken on Oct. 28 by NASA’s OSIRIS-REx spacecraft, this image shows the collector head after it was separated from the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) arm. The collector head is secured onto the capture ring in the Sample Return Capsule.

The image was captured by the StowCam camera. StowCam, a color imager, is one of three cameras comprising TAGCAMS (the Touch-and-Go Camera System), which is part of OSIRIS-REx’s guidance, navigation, and control system. TAGCAMS was designed, built and tested by Malin Space Science Systems; Lockheed Martin integrated TAGCAMS to the OSIRIS-REx spacecraft and operates TAGCAMS.

5. Freund - StowCam SRC Close

Captured on Oct. 28, this imaging sequence shows NASA’s OSIRIS-REx spacecraft completing the final step of the sample stowage process: closing its SRC. To seal the SRC, the spacecraft closes the lid and then secures two internal latches. The sample of Bennu is now safely stored and ready for its journey to Earth.
