Another hope is that by studying the samples from Bennu, scientists can compare their results against the data they obtained from instruments on board the spacecraft.

This ground-truthing' means they can then calibrate the latter, allowing them to more accurately explore differences in composition across the surface of Bennu. Remember - the samples that are heading from Earth only came from one small crater on the asteroid.
