OSIRIS-REX is NASA & # 39; s first mission to visit an asteroid near the Earth, explore the surface, collect a sample and safely return it to Earth. The spacecraft has traveled 8 billion miles (1.8 billion km) since its launch and is scheduled to arrive in Bennu on December 3rd.

"Now that OSIRIS-REx is close enough to observe Bennu, the mission team will learn as much as possible in the coming months about Bennu's size, shape, surface properties and environment before the spacecraft reaches the asteroid," says Dante Lauretta, OSIRIS -REx principal investigator at the University of Arizona, Tucson. "After so long planning for this moment, I can not wait to see what Bennu reveals to us."

While OSIRIS-REx is approaching the asteroid, the spacecraft uses its scientific tools to gather information about Bennu and prepare for arrival. The scientific charge of the spacecraft includes the OCAMS camera series (PolyCam, MapCam and SamCam), the OTES thermal spectrometer, the OVIRS visible and infrared spectrometer, the OLA laser altimeter and the REXIS X-ray spectrometer.

During the approach phase of the mission OSIRIS-REx will:

  • Regularly observe the area around the asteroid to search for dust plumes and natural satellites and study Bennu's light and spectral properties;
  • Perform a series of four asteroid approach maneuvers, starting on October 1, slowing the spacecraft to match Bennu's orbit around the sun;
  • Throw out the protective cover of the spacecraft's sampling arm mid-October and then widen and image the arm for the first time in flight; and
  • Use OCAMS to reveal the general shape of the asteroid at the end of October and to detect the surface features of Bennu in early November.

After arriving in Bennu, the spacecraft will run the first month of the aviation of the North Pole, Equator and South Pole of Bennu, at distances between 19 and 7 km from the asteroid.

These maneuvers enable the first direct measurement of Bennu's mass, as well as observations from close to the surface. These routes will also provide the mission's navigation team with navigation in the vicinity of the asteroid.

"Bennu's low gravity offers a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "About 500 km away [500 meters] in diameter, Bennu is the smallest object ever to be curved around in a spacecraft. "

The spacecraft will extensively examine the asteroid before the mission team identifies two possible sample sites. Close examination of these sites allows the team to choose one for collecting samples planned for early July 2020. After collecting the sample, the spacecraft returns to Earth before the sample return capsule is expelled in September 2023. for landing in the Utah desert.

NASD & # 39; s Goddard Space Flight Center offers comprehensive mission management, systems engineering and security and mission security for OSIRIS-REx.


Dante Lauretta from the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the planning of the observation perception and data processing of the mission. Lockheed Martin Space in Denver has built the spacecraft and offers flight operations.

Goddard and KinetX Aerospace are responsible for navigating through the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA's New Frontiers Program.
