OSIRIS-REx's Final Haul: 121.6 Grams From Asteroid Bennu

According to NASA, the OSIRIS-REx mission has successfully collected 121.6 grams, or almost 4.3 ounces, of rock and dust from the asteroid Bennu. Universe Today reports: These samples have been a long time coming. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) was approved by NASA back in 2011 and launched in September 2016. It reached its target, the carbonaceous Apollo group asteroid 101955 Bennu, in December 2018. After spending months studying the asteroid and reconnoitring for a suitable sampling location, it selected one in December 2019. After two sampling rehearsals, the spacecraft gathered its sample on October 20th, 2020. In September 2023, the sample finally returned to Earth.

For OSIRIS-REx to be successful, it had to collect at least 60 grams of material. With a final total that is double that, it should open up more research opportunities and allow more of the material to be held untouched for future research. NASA says they will preserve 70% of the sample for the future, including for future generations. The next step is for the material to be put into containers and sent to researchers. More than 200 researchers around the world will receive samples. Many of the samples will find their way to scientists at NASA and institutions in the US, while others will go to researchers at institutions associated with the Canadian Space Agency, JAXA, and other partner nations. Canada will receive 4% of the sample, the first time that Canada's scientific community will have direct access to a returned asteroid sample.
