CAPE CANAVERAL, Fla. (AP) — NASA finally has counted up all the asteroid samples returned by a spacecraft last fall — and it’s double the rubble return goal.

Officials reported Thursday that the Osiris-Rex spacecraft collected 121.6 grams (4.29 ounces) of dust and pebbles from asteroid Bennu. That’s just over half a cup and the biggest cosmic haul ever from beyond the moon.

It took NASA longer than expected to pry open the sample container because of stuck fasteners.

The black, carbon-rich samples — the first ever collected from an asteroid by NASA — are stored at a special curation lab at Houston’s Johnson Space Center.

Osiris-Rex returned the samples last September, three years after gathering them from the asteroid. The haul for the $1 billion mission would have been greater, but rocks jammed the lid of the container following the grab and some samples floated away.
