The OSIRIS-REx Thermal Emission Spectrometer (OTES) is conducting surveys to map mineral and chemical abundances and measuring asteroid Bennu’s surface temperature and properties. OTES is the first such instrument built entirely on the Arizona State University (ASU) campus.
OSIRIS-REx is currenty orbiting Bennu from which it will collect and bring a small sample back to Earth. The mission launched September 8, 2016, from Cape Canaveral Air Force Station. As planned, the spacecraft will collect the sample in summer 2020 and return it to Earth in September 2023.
