“A journey of over a billion miles began with a single launch, as NASA’s OSIRIS-REx embarked on a mission to unlock the secrets of the early solar system.”
Take a moment to explore the significance of September 8, 2016, when NASA launched the OSIRIS-REx spacecraft—a mission designed to rendezvous with the near-Earth asteroid Bennu, collect samples, and return them to Earth. This ambitious endeavor was part of NASA’s New Frontiers program and aimed to deepen our understanding of the solar system’s origins, the formation of planets, and the potential for life beyond Earth.
The OSIRIS-REx mission stands as a testament to humanity’s relentless pursuit of knowledge and exploration. From its launch to its successful sample collection on Bennu, the mission has captivated the world with its promise of revealing clues about the early solar system and the building blocks of life. As OSIRIS-REx journeys back to Earth with its precious cargo, the mission marks a significant milestone in planetary science and asteroid study.
A Journey to the Stars | September 8, 2016
The OSIRIS-REx Mission | NASA’s Ambitious Plan
On September 8, 2016, at precisely 7:05 p.m. EDT, NASA’s OSIRIS-REx spacecraft lifted off from Cape Canaveral Air Force Station aboard an Atlas V rocket. The launch marked the beginning of a groundbreaking mission, one that aimed to answer some of the most profound questions about the origins of our solar system and the potential for life elsewhere in the universe.
OSIRIS-REx, which stands for “Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer,” was tasked with a monumental challenge: to travel to the near-Earth asteroid Bennu, study its surface, collect samples, and return those samples to Earth for analysis. The mission was part of NASA’s New Frontiers program, which focuses on high-priority scientific exploration missions. Bennu, chosen as the target for its carbon-rich composition, was believed to hold organic molecules and water—the very ingredients that could have seeded life on Earth.
The mission’s objectives were as ambitious as they were complex. By analyzing Bennu’s composition, scientists hoped to gain insights into the early solar system’s formation and the processes that led to the development of planets. Additionally, understanding Bennu’s characteristics was critical for planetary defense, as Bennu is classified as a potentially hazardous asteroid with a chance of impacting Earth in the distant future.
The Road to Bennu | A Billion-Mile Journey
After its successful launch, OSIRIS-REx began its journey toward Bennu, a journey that would take over two years. The spacecraft traveled more than a billion miles through space, using a series of precise maneuvers and gravitational assists to position itself for a rendezvous with the asteroid. The mission required meticulous planning and coordination, as even the smallest error could have jeopardized the entire endeavor.
In December 2018, OSIRIS-REx finally reached its destination. The spacecraft’s arrival at Bennu was a momentous occasion, marking the beginning of an in-depth study of the asteroid. Over the next several months, OSIRIS-REx conducted detailed mapping of Bennu’s surface, identifying potential landing sites for sample collection. The spacecraft’s instruments provided scientists with unprecedented data on Bennu’s topography, composition, and rotation, offering a glimpse into the building blocks of the solar system.
The mission’s success up to this point was a testament to the dedication and expertise of the NASA team. The intricate dance between spacecraft and asteroid required precision and patience, as OSIRIS-REx slowly maneuvered closer to Bennu’s surface in preparation for the next critical phase of the mission.
Touching the Past | Sample Collection and Beyond
The Moment of Contact | OSIRIS-REx’s Historic Touchdown
On October 20, 2020, the OSIRIS-REx spacecraft made history when it successfully executed a Touch-And-Go (TAG) maneuver, briefly touching down on Bennu’s surface to collect samples. The maneuver was a carefully choreographed operation that involved the spacecraft extending its robotic arm, known as the Touch-And-Go Sample Acquisition Mechanism (TAGSAM), to gather material from Bennu’s surface.
The TAG event lasted only a few seconds, but its impact was monumental. During the brief contact, OSIRIS-REx’s TAGSAM collected samples of regolith—the loose, fragmented material covering Bennu’s surface. The mission’s engineers celebrated as data confirmed that the spacecraft had collected more than enough material to meet the mission’s goals.
The samples collected by OSIRIS-REx represent a time capsule from the early solar system. Bennu, which is thought to have formed over 4.5 billion years ago, has remained largely unchanged since its creation. By studying these samples, scientists hope to unlock secrets about the conditions that existed when the solar system was forming and to better understand the processes that led to the emergence of life on Earth.
The Journey Home | Returning with the Prize
With the sample collection complete, OSIRIS-REx began its journey back to Earth. The spacecraft is expected to return in 2023, carrying its precious cargo of asteroid samples. Once the spacecraft re-enters Earth’s atmosphere, it will release a capsule containing the samples, which will parachute down to the Utah Test and Training Range in the United States.
The return of OSIRIS-REx and its samples will mark the culmination of years of planning, execution, and discovery. The data gathered from Bennu, combined with the physical samples, will provide scientists with invaluable information that could reshape our understanding of the solar system’s history. The mission also sets the stage for future asteroid exploration and sample return missions, paving the way for new discoveries and advancements in planetary science.
