Celebrated the one year anniversary of the double asteroid redirection test
The sample was taken three years ago from an asteroid called Bennu, which orbits Earth every six years.
Bennu is about 500 meters in diameter.
The carbon-rich asteroid was discovered in 1999.
Scientists believe that it was formed around 4.5 billion years ago...
The collection of rocks will be taken to NASA's Johnson Space Center in Houston ...
The OSIRIS-REX spacecraft will stay in space to fly on to another asteroid called Apophis.
