OSIRIS-REx (acronyme de Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer) est une mission de la NASA (l'agence spatiale américaine), qui a pour objet d'étudier l'astéroïde Bénou et de ramener un échantillon de sol sur Terre. On Oct. 20, 2020, the University of Arizona-led OSIRIS-REx mission successfully collected a sample from asteroid Bennu. OSIRIS-REx will travel to a near-Earth asteroid called Bennu, reaching its target in 2018. OSIRIS-REx's handlers now plan to stow the collected material in the probe's return capsule as soon as possible, to minimize the material lost. She has two decades of experience managing space mission operations at the University of Arizona’s Lunar and Planetary Laboratory, with a particular emphasis on spacecraft instrument operations. Within this timeframe, the spacecraft’s PolyCam imager will obtain high-resolution images of Bennu’s northern and southern hemispheres and its equatorial region. It was determined that the mylar flap that allowed particles in but not out was jammed open with material. Toward the end, the distance decreased at a rate of 4 inches (10 centimeters) per second, or less than a tenth of walking speed. OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid-study and sample-return mission. The OSIRIS-REx team is now preparing the spacecraft for the next phase of the mission, the return cruise to Earth. OSIRIS-REx will image Bennu for 5.9 hours, which is just over a full rotation period of the asteroid. Tags College of Science OSIRIS-REx Research. The OSIRIS-REx team decided to add this last flyover after Bennu’s surface was significantly disturbed by the sample collection event. Ground teams planned to compare the data to a similar maneuver performed before OSIRIS-REx collected its sample from Bennu to estimate … We conducted a series of maneuvers with the main engine, Trajectory Correction Maneuver, and Attitude Control System thruster sets to slow the OSIRIS-REx approach to Bennu and achieve rendezvous on December 3, 2018. The OSIRIS-REx team took it slow and steady, sending commands that took the spacecraft through a four-hour descent sequence. The OSIRIS-REx team added this flyby to document surface changes resulting from the Touch and Go (TAG) sample collection maneuver on October 20. April die Stelle, an der sie Materialproben des Asteroiden entnommen hatte. These findings could serve as a cornerstone for future planetary missions that seek to better characterize and understand how these small bodies behave and evolve. As Bennu unveils more of itself, the OSIRIS-REx team continues to discover that this small world is glowingly complex. Stowage and Return. Osiris-Rex hat als erste NASA-Sonde überhaupt erfolgreich einen Asteroiden besucht, um Bodenproben zu entnehmen. The OSIRIS-Rex team has made two big decisions since the touch-and-go event. As OSIRIS-REx closes in on its target destination, the asteroid Bennu, anticipation is building for the first-ever, closeup glimpse of this prominent clump of rock. Die Nasa-Sonde „Osiris-Rex“ hat bei ihrem Einsatz auf dem Asteroiden Bennu eine ziemliches Durcheinander hinterlassen. Now the mission team is … One Mission, Multiple Objectives . The OSIRIS-REx team added this flyby to document surface changes resulting from the Touch and Go (TAG) sample collection maneuver on October 20, 2020. In a series of eleven papers published in the Journal of Geophysical Research: Planets and the journal Earth and Space Science, the team reports detailed observations of this activity. The mission's primary goal is to obtain a sample of at least 60 g (2.1 oz) from 101955 Bennu, a carbonaceous near-Earth asteroid, and return the sample to Earth for a detailed analysis. OSIRIS-REx scooped up so much rock, dust, and debris from Bennu that its sampling container became jammed, causing asteroid bits to leak into outer space. The OSIRIS-REx team expedited the stowage process to mitigate the chance of losing more particles. This paper describes the trajectory … Topics Science and Technology. The Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) was selected as the third mission of NASA's New Frontiers Program. Die NASA-Raumsonde Osiris-Rex hat erfolgreich auf dem Asteroiden "Bennu" aufgesetzt. Two days after touching down on asteroid Bennu, NASA’s OSIRIS-REx mission team received on Thursday, Oct. 22, images that confirm the spacecraft has collected more than enough material to meet one of its main mission requirements – acquiring at least 2 … Die Sonde fotografierte bei ihrem letzten Vorbeiflug am 7. The team will then compare these new images with the previous high-resolution imagery of the asteroid obtained during 2019. Heather Enos is deputy principal investigator of the OSIRIS-REx Asteroid Sample Return Mission. Asteroidenmission Osiris-Rex Staubsauger beim Asteroiden Bennu . Share. The OSIRIS-REx team will now focus on preparing the spacecraft for the next phase of the mission—Earth Return Cruise. Between August and December 2018, the OSIRIS-REx team acquired the first optical observations of Bennu and used them for navigation.
