The NASA OSIRIS-REx spacecraft has been related to the asteroid Bennu since three December 2018. That day, it handed from one astreoid to a different. Since then, he has surveyed and mapped Bennu.
OSIRIS-REx (Origins, spectral interpretation, useful resource identification, safety, Regolith Explorer) has simply taken a brand new step. On June 12, the spacecraft carried out one other maneuver and broke its personal document for the closest orbit of a planetary physique by a spaceship.
This marked the start of a brand new part of the OSIRIS-REx mission known as Orbital B. The orbit B orbits across the asteroid Bennu at an altitude of 680 meters (2,231 toes ). (This beats his personal earlier document of 1.three km (zero.eight mile) above the floor.)

. OSIRIS-REx will stay in orbit B till the second week of August. After that, it should enhance its orbit to 1.three km above the floor. Through the first two weeks of Orbital B, the spacecraft will research particles ejected into area. When he arrived at Bennu, he first noticed these particles, and scientists wish to research by incessantly taking photos of the asteroid 's horizon.
This picture of the asteroid Bennu was taken at an altitude of solely 690 m (zero.6 km) from the floor of the asteroid. It was captured by NavCam 1, certainly one of three cameras within the TAGCAMS (Contact Digicam System) suite of the probe. The biggest block of residents of the asteroid is on the decrease edge. At this decision, particulars as small as zero.5m may be resolved within the middle of the picture. Picture credit score: NASA / Goddard / College of Arizona / Lockheed Martin
One of many limitations to profitable pattern assortment is the sudden rocky character of Bennu's floor. The pattern assortment portion of the mission known as Contact-And-Go (TAG) and the rock floor signifies that the TAG plans must be adjusted.
