Gravity assist with Earth After a year orbiting the Sun, OSIRIS-REx receives a " nudge" from Earth's gravity, sending it on its path to asteroid Bennu. |
|
|
Approach phase begins About two million kilometres away from the asteroid, the spacecraft begins its approach phase. OSIRIS-REx sends its first pictures of Bennu back to Earth. |

OSIRIS-REx surveys Bennu OSIRIS-REx arrives at Bennu. The spacecraft's instruments survey the asteroid, creating a 3D map of its surface features and shape. |
| to |
Sample rehearsal The spacecraft performs flight paths designed to ensure that it can reach the sampling site safely. OSIRIS-REx rehearses its sampling manoeuvres. |
|
OSIRIS-REx samples Bennu OSIRIS-REx deploys its Touch-and-Go Sample Acquisition Mechanism (TAGSAM), which touches down briefly on Bennu's surface and collects a sample. The collected material is safely stored in the sample return capsule. |
|
|
Return cruise The spacecraft begins its journey back to Earth. |
|
|
Sample delivery to Earth Just outside Earth's atmosphere, OSIRIS-REx releases the Sample Return Capsule for touchdown in the Utah Test and Training Range. The spacecraft sends itself into a stable orbit around the Sun. |
