This is the best summary I could come up with:

NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) launched in 2016 destined for an asteroid named Bennu.

Now, the rocky samples — roughly 250 grams in total, the largest ever to return to Earth — are on their way to be studied by science teams, including those from Canada.

That’s thanks to our contribution of the OSIRIS-REx Laser Altimeter (OLA), an instrument that mapped out the asteroid in 3D in order to find a good place for the sample collection.

“It’s tough to put into words,” said Tim Haltigin, planetary senior mission scientist with the Canadian Space Agency (CSA) earlier this week.

From there, it will be taken by helicopter to a clean lab and transported to its home at NASA’s Johnson Space Center in Houston, Texas, the next day.

While four per cent of 250 grams may not seem like a lot, Caroline-Emmanuelle Morisset, a program scientist in space exploration development at the CSA, says that’s plenty.
