The Historic Landing of OSIRIS-REx
OSIRIS-REx and Asteroid Bennu
On December 3, 2020, NASA's OSIRIS-REx spacecraft made an unprecedented landing on the surface of the asteroid Bennu. This major achievement marked the first time a US spacecraft landed on an asteroid and aimed to collect samples. The mission was launched in 2016 with the primary goal of obtaining a piece of Bennu, which is about 4.5 billion years old and contains essential clues about the early solar system.
The Touch-and-Go Maneuver
The landing was not a prolonged stay, but rather a brief "touch-and-go" maneuver, lasting just a few seconds. OSIRIS-REx extended its robotic sampling arm to reach out and collect material from Bennu's surface, cleverly named "Nightingale" for its sampling site. The spacecraft collected an estimated 60 grams of material that will help scientists understand the building blocks of life and planetary evolution.
The Significance of Collecting Samples from Bennu
Insights into the Early Solar System
The samples collected from Bennu are more than just rocks; they are time capsules that offer vital information about the origins of our planet and life itself. Researchers believe that asteroids like Bennu are remnants from the early solar system, which means studying their composition could unveil secrets about the universe's formation and the conditions that led to the emergence of life.
The Legacy of the Apollo Missions
Much like the Apollo missions to the Moon, OSIRIS-REx is poised to bring back the largest sample of extraterrestrial material since then. The Apollo missions helped pave the way for space exploration and scientific discovery, and now OSIRIS-REx promises to expand our understanding of the cosmos in a similarly impactful manner.
Fun Fact
OSIRIS-REx’s Interesting Heritage
Interestingly, the name OSIRIS-REx stands for “Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer.” Reflecting both the scientific goals and the mission's focus on asteroids, it underscores the significance of space resource exploration for future missions.
