NASA’s OSIRIS-REx spacecraft has completed its mission by securely bringing back samples of asteroid Bennu, culminating its journey with a calculated landing in Utah.
For the first time, the United States has procured geological samples of an asteroid. The OSIRIS-REx capsule, containing material from Bennu, arrived at the Utah Test and Training Range, overseen by the Department of Defense, at 10:52 a.m. Eastern Daylight Time (8:52 a.m. Mountain Daylight Time).
Radar information from the Utah Test and Training Range authenticated that the capsule punctually penetrated Earth’s atmosphere at 10:42 a.m. Eastern Daylight Time (8:42 a.m. Mountain Daylight Time), just off California’s coastline.
Upon entering the Earth’s atmosphere, the capsule’s drogue parachute, the smaller of the two parachutes, was deployed for stabilization and later detached. The main parachute was activated at 10:47 a.m. EDT, effectively reducing the capsule’s velocity from hypersonic speeds to approximately 11 miles per hour by the moment it made contact with the ground.

OSIRIS-REx: Probing the Celestial Bodies to Reveal Cosmic Origins
Exploring the cosmos often necessitates voyages beyond Earth. Herein lies the audacity of NASA’s OSIRIS-REx mission, designed to interact with a celestial object as ancient as our solar system.
The mission, formally known as Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer, was more than just a complex nomenclature; it was a multi-objective mission of profound importance. Initiated in September 2016, its primary mission was to meet with Bennu, an asteroid in close proximity to Earth.
So, what makes Bennu special?
Bennu is believed to be a carbonaceous celestial body, preserving remnants from the formation of our solar system. It holds the potential to offer invaluable insights into life’s building blocks, the genesis of organic compounds, and the primeval conditions that led to life on Earth.
This mission was not a mere flyby. OSIRIS-REx had the assignment to investigate Bennu thoroughly, mapping its landscape in great detail before extending its robotic arm to collect samples. This procedure, referred to as the Touch-And-Go (TAG) operation, was a critical juncture in which the spacecraft fleetingly touched the asteroid to collect irreplaceable material, known as regolith.
Yet, the task was not devoid of hurdles. Bennu presented an unexpected challenge with its rocky terrain, making the TAG operation inherently risky. Nonetheless, the spacecraft succeeded in obtaining its sample in October 2020.
The mission reached its climax as the sample was returned to Earth just recently. This enables scientists to physically analyze material that has remained unaltered for billions of years. In addition to its scientific goals, OSIRIS-REx also contributes vital data regarding asteroid behavior that may be critical in designing future strategies for planetary defense against potential asteroid threats.
In summary, the OSIRIS-REx mission is not just a cosmic expedition; it serves as a conduit to our ancestral roots, a window into our galactic environs, and a harbinger for future celestial explorations.
Frequently Asked Questions (FAQs) about OSIRIS-REx Mission
What is the primary focus of the OSIRIS-REx mission?
The primary focus of the OSIRIS-REx mission was to rendezvous with the near-Earth asteroid Bennu, thoroughly survey it, and collect samples of its regolith (rock and dust) to bring back to Earth for analysis.
When was the OSIRIS-REx spacecraft launched?
The OSIRIS-REx spacecraft was launched in September 2016 with the primary objective of meeting and collecting samples from asteroid Bennu.
Where did the OSIRIS-REx capsule land upon its return to Earth?
The OSIRIS-REx capsule safely landed at the Department of Defense’s Utah Test and Training Range at 10:52 a.m. Eastern Daylight Time (8:52 a.m. Mountain Daylight Time).
How did the capsule safely land back on Earth?
The capsule employed two parachutes to ensure a safe landing. A drogue parachute was first deployed upon entering Earth’s atmosphere to stabilize the capsule. This was later detached, and the main parachute was deployed at 10:47 a.m. EDT, slowing the capsule from hypersonic speeds to approximately 11 miles per hour by the time it touched the ground.
What makes asteroid Bennu scientifically significant?
Asteroid Bennu is believed to be a carbon-rich celestial body that holds remnants from the early days of our solar system. It offers the potential for invaluable insights into life’s building blocks, the genesis of organic compounds, and the primeval conditions that led to life on Earth.
What challenges did the mission face during the sample collection?
The sample collection, known as the Touch-And-Go (TAG) operation, faced significant challenges due to Bennu’s rocky and boulder-strewn terrain. Despite these challenges, the mission was successful in obtaining a sample in October 2020.
What are the future implications of the OSIRIS-REx mission?
Beyond its primary scientific objectives, the OSIRIS-REx mission also provides critical data on asteroid behavior, which may prove invaluable in future planetary defense strategies against potential asteroid impacts. The mission serves as a conduit to our ancestral roots, a window into our galactic environment, and a harbinger for future celestial explorations.
When was the sample from Bennu collected?
The sample from asteroid Bennu was collected by the OSIRIS-REx spacecraft in October 2020.
What will happen to the returned sample?
The returned sample will allow scientists to physically analyze material that has remained unaltered for billions of years, offering a unique opportunity for scientific research into the origins of our solar system and possibly life itself.

From launching in 2016 to collecting the sample in 2020 and safely returning, this mission is a massive achievement. What’s next? Mars? Moon? Cant wait to find out.
Landing back in Utah? That’s precision engineering for ya. Kudos to all the engineers involved in the mission.
Incredible feat by NASA, yet again! Does anyone know what the sample might reveal about the early solar system? I’m super curious.
So we’re spending billions on collecting rocks from space? Hope it’s worth it.
While the mission is commendable, one has to wonder about the allocation of resources. Is this the best way to use taxpayer money?
Wow, this is mind-blowing stuff. I cant believe we’re getting samples from actual asteroids now. What a time to be alive!
A bridge to our past and a beacon for future explorations, well said. Looking forward to the next big thing in space exploration.
I’m interested in what this means for the study of organic molecules. Bennu could hold clues to the origins of life, thats amazing.
Great, but what about climate change? Shouldn’t we focus on saving our planet first?
this is just the beginning guys. Imagine what we’ll discover in the next decade. OSIRIS-REx is a game changer for sure.
