Asteroid Samples Taken From Asteroid Landing Today

"Anticipation is palpable. We've been gearing up for this very moment..."


As the clock ticks towards a monumental moment, fragments of an asteroid—ancient relics that could unlock secrets of our solar system’s infancy and the potential birth of Earth’s water—are set to grace the Utah desert this Sunday.

NASA’s ambitious OSIRIS-REx mission had one clear objective: retrieve a significant sample from the near-Earth asteroid, Bennu. The endeavor, which began over ten years ago, saw a milestone in 2020 when the spacecraft successfully harvested its precious cargo. This weekend marks another crucial phase as it approaches Earth to dispatch the capsule holding the asteroid pieces.


“Anticipation is palpable. We’ve been gearing up for this very moment,” articulated Lori Glaze, a key figure at NASA’s Planetary Science Division.

Deciphering the Dawn of Our Cosmic Residence

What makes these asteroid fragments invaluable? These remnants are essentially time capsules, unchanged since our solar system’s dawn. By studying them, researchers can glean insights into the materials present during our cosmic neighborhood’s formative years. Moreover, asteroids might hold the key to Earth’s hydrological mysteries.

“Asteroids could have been instrumental in shaping Earth, especially in contributing to our water reservoirs,” stated Glaze.

While the exact weight of the sample remains unknown, scientists speculate it might be the heftiest ever retrieved from an asteroid—equivalent to a hamster. This impressive haul promises an unprecedented scope of study.


Unforeseen Hitches and Quick Reflexes

OSIRIS-REx’s rendezvous with Bennu wasn’t without its challenges. The spacecraft scooped up more material than anticipated, causing a minor glitch. The overflow resulted in some particles escaping into the void. Opting for caution, NASA promptly stored the remaining samples to ensure their safety.

Setting off from Bennu in 2021, the spacecraft has been Earth-bound, and come Sunday, it will near our planet at a proximity of 63,000 miles. Yet, this homecoming is fraught with uncertainties.

High Stakes in the Homestretch

Launching the sample container—a tire-sized object—into space is the primary concern. If the ejection falters, OSIRIS-REx would need another orbital lap around the sun before another attempt in 2025.

After its release, the container will be at the mercy of gravity and momentum. “Once dispatched, it simply becomes a falling object with no directional controls,” mentioned Sandy Freund, Lockheed Martin’s OSIRIS-REx program manager.

The intense atmospheric re-entry will see the container blaze at approximately 5,000 degrees Fahrenheit. A heat shield will play a pivotal role in safeguarding the sample from incineration—a catastrophic end.

Amidst potential pitfalls, there’s a beacon of hope. Advanced preparations, coupled with innovative technology and learnings from past missions, embolden the team’s confidence. Radar systems and aircraft will vigilantly monitor the container’s descent.


Assuming a smooth touchdown, the container will journey to NASA’s Johnson Space Center in Houston, with its cosmic treasures set for a public unveiling in October.

Freund concludes, “This mission, besides its scientific import, paves the way for potential asteroid resource extraction in the future.”
