NASA spacecraft Osiris-rex was launched into space to collect a part of an asteroid that will be used as a building block to understand the beginning of the solar system. Osiris-rex launched in 2016 and arrived in Bennu in late 2018, however, the sample collected will not be returned to Earth until 2023. The Assistant Professor in the Physics and Astronomy department at NAU, Cristina Thomas, says this particular mission has a lot to offer.
