NASA works to secure the OSIRIS-REx asteroid sample

The mission has canceled tomorrow’s Sample Mass Measurement to protect the sample and is now on course to stow the sample as soon as possible. The spacecraft remains in good health and the mission is confident that the spacecraft has collected more than 60 grams of material.

NASA associate administrator Thomas Zurbuchen said in a statement that “although we may have to move more quickly to stow the sample, it’s not a bad problem to have. We are so excited to see what appears to be an abundant sample that will inspire science for decades beyond this historic moment.” Dante Lauretta leads the science team and said “The loss of mass is of concern to me, so I’m strongly encouraging the team to stow this precious sample as quickly as possible.”

Based on the data, they believe the head has “much more than 2 ounces of regolith,” and they’ve adjusted their plans in order to stow it away as quickly as possible. A planned measurement that would’ve spun the sampling arm to help determine the mass of the sample has been canceled, as well as a braking burn for the craft.
