It appears like Bennu was in fact the ideal target for NASA’s first-at any time asteroid sample-return mission.
That mission, OSIRIS-REx, sent pieces of the 1,650-foot-vast (500 meters) Bennu to Earth late very last thirty day period. NASA gave the planet its first look at the sample these days (Oct. 11) in the course of a live webcast event, which also offered a rundown of the initially analyses performed on the off-Earth product.
“The OSIRIS-REx sample is the major carbon-rich asteroid sample at any time sent to Earth and will help experts look into the origins of existence on our very own earth for generations to occur,” NASA Administrator Invoice Nelson claimed in a statement nowadays.
“Virtually every thing we do at NASA seeks to remedy issues about who we are and exactly where we arrive from,” Nelson extra. “NASA missions like OSIRIS-REx will boost our knowledge of asteroids that could threaten Earth though giving us a glimpse into what lies over and above. The sample has designed it again to Earth, but there is however so considerably science to arrive — science like we’ve hardly ever seen prior to.”
OSIRIS-REx released in September 2016 and arrived at Bennu in December 2018. The probe expended the up coming 22 months researching the place rock from orbit and searching for the correct position to swoop down and seize a sample.
That sampling operate took place in October 2020, and it offered a fair bit of drama: Bennu’s floor turned out to be shockingly porous, and OSIRIS-REx sank deeply into it.
But the probe emerged with a bounty — so considerably content that its assortment system acquired clogged, letting some asteroid dirt and pebbles to escape into room. OSIRIS-REx continue to managed to safe most of the Bennu bits in its sample container, and the probe headed toward Earth in May possibly 2021.
The journey household wrapped up on Sept. 24, when OSIRIS-REx’s return capsule landed in the desert of northern Utah. A day later, the sample arrived at NASA’s Johnson House Center (JSC) in Houston, the place it’s being processed, curated and saved.
That function has only just started. For instance, mission staff users continue to never know particularly how substantially product OSIRIS-REx hauled household. They feel it truly is about 8.8 ounces (250 grams) — far increased than the mission need of 2.1 ounces (60 g) — but which is just an estimate, calculated while the return capsule was however in area.
JSC will distribute sections of the Bennu sample over the coming months and yrs to scientists around the environment, who will study it in fantastic detail.
Their get the job done will ascertain, among the other points, the identification of the carbon compounds, which could get rid of mild on how daily life received started out right here on Earth. (Many researchers feel carbon-prosperous asteroids like Bennu seeded our world with life’s building blocks extensive in the past, through impacts.)
And Bennu is a relic of our solar program‘s planet-building period, so getting the rock’s measure will help us fully grasp the development and evolution of our cosmic backyard on a bigger scale, mission workforce users reported.
“As we peer into the historic tricks preserved inside of the dust and rocks of asteroid Bennu, we are unlocking a time capsule that gives us profound insights into the origins of our solar technique,” Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, reported in the similar assertion.
“The bounty of carbon-wealthy materials and the plentiful existence of drinking water-bearing clay minerals are just the suggestion of the cosmic iceberg,” he mentioned. “These discoveries, manufactured achievable through yrs of devoted collaboration and slicing-edge science, propel us on a journey to fully grasp not only our celestial community but also the possible for life’s beginnings. With every revelation from Bennu, we draw closer to unraveling the mysteries of our cosmic heritage.”
The journey isn’t really in excess of for the OSIRIS-REx spacecraft, by the way. While its return capsule is now back again on Earth, the probe retains on traveling, toward a different asteroid called Apophis. OSIRIS-REx is scheduled to get there at that area rock in 2029 and examine it up close, on an prolonged mission called OSIRIS-APEX.
