help Dante Lauretta FAQ
What was Dante Lauretta's role in OSIRIS-REx?
Lauretta served as principal investigator of NASA's OSIRIS-REx asteroid sample-return mission. The University of Arizona led the mission's science operations, while NASA Goddard managed major engineering and navigation responsibilities.
Why did Lauretta's team choose asteroid Bennu?
Bennu is a carbon-rich near-Earth asteroid whose material may preserve evidence from the early solar system. Its orbit, size, and scientific value also made it a practical target for sample collection and return.
Did OSIRIS-REx actually land on Bennu?
It performed a brief touch-and-go collection in 2020 rather than a conventional sustained landing. The spacecraft used its TAGSAM mechanism to disturb the surface and capture dust and rock before backing away.
What happened to OSIRIS-REx after the Bennu sample reached Earth?
The sample capsule returned to Earth in 2023 for laboratory analysis. The spacecraft continued on an extended mission named OSIRIS-APEX, targeting asteroid Apophis.
