The Origins of OSIRIS-REx

OSIRIS-REx, also known as the Origins Spectral Interpretation Resource Identification Security � Regolith Explorer, is a NASA mission that was launched in 2016. The main goal of this mission was to explore the near-Earth asteroid Bennu and bring back samples of the asteroid to Earth for further analysis.

The Spectral Interpretation of Bennu

One of the key objectives of the OSIRIS-REx mission was to study the spectral properties of Bennu. Spectral analysis involves studying the light that is reflected off of a surface and breaking it down into its individual wavelengths. This can provide information about the minerals and other substances that are present on the surface of an object.

The OSIRIS-REx mission used a number of instruments to study the spectral properties of Bennu, including the OSIRIS-REx Thermal Emission Spectrometer (OTES) and the OSIRIS-REx Visible and Infrared Spectrometer (OVIRS). These instruments were able to detect the presence of various minerals on Bennu, including water-altered minerals, which suggests that the asteroid may have had liquid water on its surface in the past.

The Resource Identification of Bennu

In addition to studying the spectral properties of Bennu, the OSIRIS-REx mission also aimed to identify the resources that are present on the asteroid. Bennu is believed to contain a variety of valuable minerals, including gold and platinum, and the OSIRIS-REx mission was designed to help determine the abundance and distribution of these minerals on the asteroid.

The Security of Bennu

One of the key reasons for studying Bennu is its potential threat to Earth. Bennu is classified as a potentially hazardous object, meaning that it has a very small chance of impacting Earth in the next century. By studying Bennu and understanding more about its composition and trajectory, scientists hope to be better prepared to deal with any potential impacts from the asteroid.

The Regolith Explorer

The OSIRIS-REx mission also included the deployment of a small robot called the Regolith Explorer, or REXIS for short. REXIS was designed to explore the surface of Bennu and collect data on the composition and properties of the asteroid’s regolith, or surface material.

Returning to Earth

After spending four years exploring Bennu, the OSIRIS-REx spacecraft is now on its way back to Earth. The spacecraft is carrying up to a kilogram of precious asteroid samples that were collected during its mission. If all goes well, the capsule containing the samples will detach from the spacecraft and enter the Earth’s atmosphere on September 24th, where it will parachute to a soft landing in the deserts of Utah.

The OSIRIS-REx mission is the second successful asteroid sample return mission, following the Japanese Space Agency’s Hayabusa 2 mission in 2020. The samples collected by OSIRIS-REx will be carefully analyzed by scientists to learn more about the origins and history of Bennu, as well as the early Solar System as a whole.
