OSIRIS-REx Mission and the Bennu Asteroid
the OSIRIS-REx project, managed under the scientific guidance and spacecraft control of the Goddard Space Flight Center in Greenbelt, Maryland, was primarily designed to study and collect samples from the asteroid Bennu. This asteroid, approximately half a kilometer in diameter, has attracted considerable attention due to its proximity to Earth and a small, but not insignificant, risk of a potential collision in the distant future.
Bennu orbits the sun at an average distance of 168 million kilometers, slightly farther than Earth’s 150 million kilometers. Notably, it makes close approaches to Earth every six years, coming within approximately 299,000 kilometers. This distance is closer than the moon’s average distance of 380,000 kilometers, highlighting the importance of understanding Bennu’s trajectory and composition.
NASA’s decision to target Bennu for study and sample collection was driven by the belief that the asteroid represents a relic from the early solar system. It is considered a “time capsule,” preserving materials from the solar system’s infancy. Scientists hoped to find evidence of components that could shed light on the origin of life on Earth, making Bennu a prime target for unlocking the secrets of our cosmic origins.
The Origin of the Name “Bennu”
Originally discovered in 1999 and designated as 1999 RQ36, the asteroid was later named Bennu (designated 101955 Bennu) through an international contest associated with the OSIRIS-REx project.The naming process itself highlights the mission’s commitment to public engagement and education.
The Planetary Society,in collaboration with Arizona University and the LINEAR Project,which monitors near-Earth objects,organized the contest in 2012. The winning name was submitted by Michael Puzio, a then-9-year-old third-grade student from North Carolina.His suggestion was chosen from over eight thousand entries, demonstrating the widespread interest in space exploration and asteroid research.
Bennu, in Egyptian mythology, is the name of a bird associated with rebirth.Michael Puzio chose the name because the OSIRIS-REx spacecraft has a long arm that extends to collect samples from the asteroid, reminiscent of the bird-like depiction of the Egyptian god Osiris.Bennu is linked to the god Osiris, representing “new birth” and is frequently enough seen as a prototype for mythical birds like the phoenix, which “revives from death.” This connection between ancient mythology and modern science adds a layer of cultural significance to the mission.
The name OSIRIS-REx itself is an acronym that reflects the mission’s goals:
- O – Origin
- Si – Spectral Interpretation
- Ri – Resource Identification
- S – Security (related to near-Earth object studies)
- REx – Regolith Explorer
Combined, OSIRIS-REx represents a mission to explore the origin of the Bennu asteroid and the solar system through spectral analysis, resource identification, studying the risk of the asteroid posing a threat to Earth, and exploring the regolith, the loose rock and soil on the asteroid’s surface. The acronym encapsulates the multifaceted nature of the mission and its scientific objectives.
The Operations of OSIRIS-REx
The OSIRIS-REx spacecraft launched from Earth on August 8, 2016, and arrived at the Bennu asteroid on December 3, 2018. For two years, it orbited Bennu, meticulously studying the asteroid’s surface to identify a suitable location for sample collection. This careful reconnaissance was crucial for ensuring the success of the sample retrieval operation.
On October 20, 2020, OSIRIS-REx successfully touched down on Bennu, using its robotic arm to collect samples from the asteroid’s surface. The mission successfully gathered approximately 121.6 grams of material. This achievement marked a significant milestone in space exploration, demonstrating the feasibility of retrieving samples from asteroids and returning them to Earth for analysis.
After completing the sample collection and asteroid exploration as planned, OSIRIS-REx began its journey back to Earth on May 10, 2021, carrying the precious cargo from Bennu. The return journey was a carefully calculated trajectory, ensuring the safe delivery of the samples to Earth.
On September 24, 2023, the sample capsule successfully landed in the Utah desert, marking the culmination of years of planning and execution. The samples were then transported to specialized laboratories for detailed analysis, leading to the groundbreaking findings announced on january 29, 2025.
