After a decade and $1.2 billion, NASA reveals its booty from Bennu: 121 grams
The asteroid sample returned from Bennu is 4.29 ounces (121.6 grams), equivalent to half a cup of sugar or a small avocado.
NASA invested $1.2 billion and nearly a decade to retrieve this small amount of asteroid dust, but it is 20 times greater than previous missions.
The sample retrieval exceeded the minimum requirement for the mission and is considered a success by NASA.
