Now that the 'boop' has been completed (with spectacular success!), we'll move the discussion to here for subsequent mission events.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The OSIRIS-REx team used an alternative method to determine the sample mass.
Alternative Sample Mass Measurement Technique for OSIRIS-REX Sample Collection Phase https://arxiv.org/abs/2109.05561 QUOTE ...The alternative SMM technique utilized reaction wheel momentum data from identical TAGSAM movements prior to and following the TAG event to estimate changes in spacecraft moment of inertia. Conservation of momentum was used to isolate the sample mass from this inertia change. Using this new method, the spacecraft team was able to successfully estimate collected sample mass to be 250.37 +/- 101 g.

Alternative Sample Mass Measurement Technique for OSIRIS-REX Sample Collection Phase https://arxiv.org/abs/2109.05561 That's a clever approach. They collected ~4-6 times more material than their mission success criteria! I was thinking that with the sampling head literally overflowing, it might be even more. Perhaps a lot of porosity? Looking forward to the return of the samples. -------------------- |
