NASA's Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) mission is a robotic spacecraft designed to explore the near-Earth asteroid Bennu and return a sample to Earth. The OSIRIS-REx mission will help us learn more about the origins of our solar system, and how asteroids can be used as resources for future space missions.
The OSIRIS-REx spacecraft was launched on September 8, 2016, and arrived at Bennu on December 3, 2018. The spacecraft spent two years studying Bennu, using a variety of instruments to map the asteroid's surface, measure its composition, and collect samples of its regolith.
On October 20, 2020, the OSIRIS-REx spacecraft successfully touched down on Bennu and collected a sample of the asteroid's regolith. The sample is currently being stored on the spacecraft and will be returned to Earth in September 2023.
The OSIRIS-REx mission is a significant step forward in our understanding of asteroids and their role in the history of our solar system. The mission's findings will help us to better understand the origins of our planet, and how we can use asteroids as resources for future space missions.
Here are some of the key findings from the OSIRIS-REx mission so far:
* Bennu is a carbonaceous asteroid, which means that it is composed of a mixture of organic compounds and water ice.
* Bennu is very porous, with a density of only about 1.19 grams per cubic centimeter.
* Bennu's surface is covered in a variety of features, including craters, boulders, and cliffs.
* Bennu's composition is similar to that of the Sun, which suggests that the asteroid may have formed in the early stages of our solar system.
* Bennu is a potential resource for future space missions, as it contains a variety of elements that could be used for life support and propulsion.
The OSIRIS-REx mission is a major success, and its findings will have a profound impact on our understanding of asteroids and their role in the history of our solar system. The mission's success is a testament to the hard work and dedication of the OSIRIS-REx team, and it is an important step forward in our exploration of the solar system.
