NASA’s OSIRIS-REx spacecraft is cruising again to Earth with a pattern it collected from the rocky floor of asteroid Bennu. When its pattern capsule parachutes down into the Utah desert on September 24, OSIRIS-REx will develop into the USA’ first-ever mission to return an asteroid pattern to Earth.
After seven years in house, together with a nail-biting landing on Bennu to assemble mud and rocks, this intrepid mission is about to face considered one of its greatest challenges but: ship the asteroid pattern to Earth whereas defending it from warmth, vibrations, and earthly contaminants.
“As soon as the pattern capsule touches down, our staff can be racing towards the clock to get well it and get it to the security of a brief clear room,” stated Mike Moreau, deputy undertaking supervisor at NASA’s Goddard Area Flight Middle in Greenbelt, Maryland.

So, over the subsequent six months, the OSIRIS-REx staff will follow and refine the procedures required to get well the pattern in Utah and transport it to a brand new lab constructed for the fabric at NASA’s Johnson Area Middle in Houston. There, scientists will unpack the pattern, distribute as much as 1 / 4 of it to the OSIRIS-REx science staff all over the world for evaluation, and curate the remaining for different scientists to check, now and in future generations.
Flight dynamics engineers from NASA Goddard and KinetX Aerospace are reviewing the trajectory that may deliver the spacecraft near Earth. At Lockheed Martin in Denver, staff members are preserving tabs on the spacecraft and making ready a gaggle to get well the pattern capsule. This summer season, crews in Colorado and Utah will follow the entire steps to get well the capsule safely, whereas defending it from contamination. At Johnson Area Middle, the curation staff is rehearsing their process to unpack and course of the pattern inside glove packing containers. In the meantime, members of the pattern science staff are making ready the investigations they'll carry out with the pattern materials as soon as obtained.

“The OSIRIS-REx staff has already carried out superb feats characterizing and sampling asteroid Bennu,” stated Dante Lauretta, OSIRIS-REx principal investigator from the College of Arizona, Tucson. “These accomplishments are the direct results of the intensive coaching and rehearsals that we carried out each step of the way in which. We're bringing that stage of self-discipline and dedication to this closing part of the flight operations.”
Asteroids are the traditional supplies left over from the unique period of planet formation and will include molecular precursors to life. Scientists have realized an important deal from finding out asteroid fragments which have naturally reached the bottom as meteorites. However to grasp whether or not asteroids performed a task in delivering these compounds to Earth’s floor over 4 billion years in the past, scientists want a pristine pattern from house, free from terrestrial contaminants.
As well as, essentially the most fragile rocks noticed on Bennu in all probability wouldn't have survived passage by way of Earth’s environment as meteorites. “There are two issues pervasive on Earth: water and biology,” stated Dr. Jason Dworkin, OSIRIS-REx undertaking scientist at NASA Goddard. “Each can severely alter meteorites once they land on the bottom and muddle the story informed by the pattern’s chemistry and mineralogy. A pristine pattern might present insights into the event of photo voltaic system.”

The curation staff can be among the many first to see and deal with the pattern OSIRIS-REx is getting back from asteroid Bennu. They're additionally accountable for storing and distributing the pattern to science staff members all over the world. Many of the pattern can be saved for future generations.

On Sept. 24, because the OSIRIS-REx spacecraft flies by Earth, it'll launch its pattern return capsule, thereby ending its main mission. The capsule, which is estimated to carry a couple of cup of Bennu’s materials – 8.8 ounces +/- 3.6 ounces (250 grams +/- 101 grams) to be exact – will land inside a 37-mile by 9-mile ellipse (59 km by 15 km) inside Division of Protection property that's a part of the Utah Check and Coaching Vary and Dugway Proving Grounds.
OSIRIS-REx staff members from NASA Goddard, KinetX, Lockheed Martin, and NASA’s Langley Analysis Middle in Hampton, Virginia, are utilizing laptop fashions to check navigation plans in varied climate, photo voltaic exercise, and house particles eventualities to make sure that when the capsule enters Earth’s environment at 10:41 a.m. ET (8:41 a.m. MT), it'll contact down contained in the focused space 13 minutes later.
Restoration crews are accountable for securing the pattern return capsule’s touchdown website and helicoptering it to a transportable clear room positioned on the vary. Moreover, crews will accumulate soil and air samples throughout the touchdown capsule. These samples will assist establish if any minute contaminants contacted the asteroid pattern.
As soon as the capsule is contained in the constructing with the moveable clear room, members of the staff will take away the warmth defend, again shell, and different parts to arrange the pattern canister for transport to Houston.
The return to Earth of samples from asteroid Bennu would be the end result of a greater than 12-year effort by NASA and its mission companions however marks the start of a brand new part of discovery as scientists from all over the world will flip their consideration to the evaluation of this distinctive and treasured materials relationship from the early formation of our photo voltaic system.
NASA’s Goddard Area Flight Middle oversees mission administration, techniques engineering, and security and mission assurance for OSIRIS-REx. The College of Arizona, Tucson, led by principal investigator Dante Lauretta, spearheads the science staff, science statement planning, and information processing. Lockheed Martin Area in Colorado constructed the spacecraft and handles flight operations, whereas Goddard and KinetX Aerospace navigate the spacecraft. Pattern curation, together with processing upon Earth arrival, will happen at NASA’s Johnson Area Middle in Houston. Worldwide collaborations embrace the Canadian Area Company’s OSIRIS-REx Laser Altimeter instrument and a partnership with the Japan Aerospace Exploration Company’s Hayabusa2 mission for asteroid pattern science. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, which is managed by NASA’s Marshall Area Flight Middle in Alabama on behalf of the Science Mission Directorate in Washington.
