    Default OSIRIS-REx Arrives at Bennu



    The spacecraft arrived at its destination, asteroid Bennu, on Monday, Dec. 3, 2018: https://www.nasa.gov/feature/goddard...s-rex-approach.

    - The spacecraft will spend a year surveying the asteroid...selecting a site to collect a sample...and then return the sample to Earth in September 2023

    Another interesting mission to track!!

    I watched the live stream yesterday - it was a bit underwhelming as I guess it really didn't amount to anything more than seeing the data on a monitor and announcing that the probe had successfully arrived. What I did appreciate was all the videos that gave the background information and all the explanations of what the probe is and what it's going to be doing.

    Realizing that getting there intact and operating properly is already a great accomplishment, the good stuff is just about to start. Looks to be a very interesting couple of years coming up.

    Hi Dave. Thanks for finding and sharing this link with us. The photograph from 50 miles out and showing the rotation is just amazing. Let's hope the sample makes it's way back here on the return trip with no problems.

    Recently analyzed data from the OSIRIS-REx mission has revealed water locked inside the clays that make up the asteroid: https://www.nasa.gov/press-release/n...er-on-asteroid.

    - "Data obtained from the spacecraft’s two spectrometers...reveal the presence of molecules that contain oxygen and hydrogen atoms bonded together"...an indication that liquid water was present at some time on Bennu’s parent body, a much larger asteroid
    - "The mission currently is performing a preliminary survey of the asteroid, flying the spacecraft in passes over Bennu’s north pole, equator, and south pole at ranges as close as 4.4 miles (7 km) to better determine the asteroid’s mass"...data that will be used to design the spacecraft's insertion into orbit

    Orbit insertion is scheduled for New Year's Eve: https://www.space.com/42706-osiris-r...n=20181216-sdc.

    The spacecraft is currently collecting lots of data while "floating free" like a hummingbird over and around the asteroid!! Sounds like fun

    With all the excitement about NH and Ultima Thule, forgot about this OSIRIS-REx achievement: https://www.asteroidmission.org/?lat...reaking-record.

    - On December 31, the spacecraft entered into orbit around the asteroid Bennu, and made Bennu the smallest object ever to be orbited by a spacecraft

    - The spacecraft will perform a series of close flybys of Bennu for several months to take high-resolution images of every square inch of the asteroid to help select a sampling site

    - During the summer of 2020, the spacecraft will briefly touch the surface of Bennu to retrieve a sample; the OSIRIS-REx mission is scheduled to deliver the sample to Earth in September 2023
