The place where NASA’s first asteroid sample-return mission was in San Francisco.
The OSIRIS-REx rocket will fly down on a place called Nightingale near the north end of the 1,650-foot-wide (500 meters) asteroid Bennu, which the investigation has been circumnavigating since December 2018, mission squad member said on 12 December 2019, during a news meeting at the annual fall conference of the American Geophysical Union (AGU).
Dante Lauretta, OSIRIS-Rex’S principal investigator and planetary scientist at the University of Arizona, told Space.com that the has been waiting for this day over a long period of time and it has involved many people who worked for a very long period of time. These people have been investigating the data that has been transferred from asteroid over a period of time.
This OSIRIS-Rex mission has cost 800 million USA dollars to research on the Solar System on the previous days and the function of carbon-rich asteroids, for example, the Bennu. These asteroids have helped in releasing life buildings blocks on the earth. Lauretta said that Nightingale had provided the group with a great opportunity to progress on those fronts.
For instance, the site has masses of soft-grained material that can be freely drawn up by the rocket’s selection mechanism. Nightingale is too adjacent to Bennu’s the North Pole, where temperatures have to keep on fairly cool over the years. So, the soil and debris up there have Lesly been altered than material near the asteroid’s center, increasing the likelihood that original organics and hydrated minerals are there to be picked.
Lauretta said during the news meeting that Nightingale sports have a lot of black materials which may be an indicator of organics. Nightingale is a small crater with the impact that appears to be young, this means that OSIRIS-Rex should have the ability to collect asteroids remains that were just unearth and exposed to simple little space weathering.
Nevertheless, Nightingale “does have some dangers accompanying it,” Lauretta said during the news conference.
For instance, if the crater will be 65 feet which are 20 meters or so in width, it will be tight for it to fit in OSIRIS-REx. OSIRIS-RExs includes a span of 20 feet which is 6m and its solar panels. And the crater is surrounded by some uneven rocks, as well as the one that Lauretta has called “Mt. Doom,” which escalates to about 33 feet which are 10m above the crater base
OSIRIS-Rex will use the following 8 months doing the investigation and on how to move within samples.
