In a monumental achievement, NASA’s OSIRIS-REx mission successfully completed its first-ever Asteroid Sample return mission from an asteroid, bringing a science capsule containing precious material from asteroid Bennu safely back to Earth. This momentous event marks the culmination of a remarkable 1.2 billion-mile journey that began in 2016. The capsule, released from the OSIRIS-REx spacecraft, descended through Earth’s atmosphere at a staggering speed of approximately 27,000 miles per hour.
Astronomical Odyssey: The OSIRIS-REx Mission
The OSIRIS-REx mission, initiated in 2016, has collected a substantial quantity of asteroid material, potentially amounting to several hundred grams. This treasure trove of celestial material holds the key to unlocking vital insights into the earliest phases of our solar system’s formation and evolution.
Melissa Morris, the program executive for OSIRIS-REx, highlighted the significance of NASA’s investment in small body missions like this one, stating, “NASA invests in small body missions like OSIRIS-REx to investigate the rich population of asteroids in our solar system that can give us clues about how the solar system formed and evolved. It’s our own origin story.”
Precision and Perfection: A Touchdown in Utah
After its breakneck reentry into Earth’s atmosphere, the science capsule was skillfully slowed down by parachutes and made its touchdown in the Department of Defense’s Utah Test and Training Range, precisely at 10:52 AM Eastern Time. This location was chosen due to its distinction as the largest restricted airspace in the United States and its history of hosting previous NASA sample return missions, such as Genesis and Stardust.
Spanning an area of 36 miles by 8.5 miles, the landing zone demanded an exceptionally high level of precision, particularly during the critical moments when OSIRIS-REx rendezvoused with asteroid Bennu and collected its Asteroid Sample in 2020. As Sandra Freund, the OSIRIS-REx program manager, emphasized in a pre-landing briefing, “The really precise navigation required to orbit Bennu and to touch down and collect our sample, we were under a meter away from our target. So that illustrates what kind of navigation precision we’ve had throughout this mission.”
Future Exploration: Analyzing the Asteroid Sample
Following a flawless landing, recovery teams wasted no time in collecting the Asteroid Sample from the Utah desert. At 12:15 PM Eastern Time, a helicopter took off, carrying the precious cargo. The science capsule will now undergo a series of meticulous procedures to ensure the integrity of the asteroid material.
The first step involves the capsule’s disassembly in a temporary clean room, where larger components like the backshell will be removed. Subsequently, a nitrogen purge will be performed, infusing nitrogen into the canister to protect the sample from Earth’s atmosphere. This crucial measure ensures that the sample remains pristine during its journey to the Johnson Space Center in Houston, Texas, where the canister will be opened for the first time, allowing scientists to analyze the asteroid material and unlock the secrets of our solar system’s distant past.
In this historic mission, NASA has not only captured a piece of the cosmos but has also paved the way for future exploration and the continuous quest to unravel the mysteries of our celestial neighborhood.
