Olivia Billett - OSIRIS-REx Spacecraft Science Lead at Lockheed Martin

This page contains interviews with personnel from the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission, edited for social media. The OSIRIS-REx spacecraft launched Sept. 8, 2016, and began orbiting asteroid Bennu on Dec. 31, 2018. Its primary science objective is to study Bennu and collect a sample for return to Earth in 2023. Bennu is a carbon-rich asteroid that records the earliest history of our solar system, and which may contain the raw ingredients of life.

What is said in the film

So one of the unique challenges of the OSIRIS-REx mission is the microgravity environment that we're going to, which is very different from us than orbiting a planet as we're used to. Without the large gravity of a planet, the navigation uncertainties affect us a lot more. And the non-gravitational forces on the spacecraft affect our trajectory in ways that make it much more dynamic from a power and thermal point of view on the spacecraft. We're also working on a much shorter turnaround times since our optical navigation has to be downlinked every day and that drives a much faster turnaround times for us from a data and downlink point of view.
