nasa's most ambitious sample collection

00:00:13,589 --> 00:00:10,880
attempt since the apollo program

00:00:25,269 --> 00:00:23,199
as osiris-rex drew near bennu grew in

00:00:28,070 --> 00:00:25,279
detail from a few tiny pixels to a

boulders the spacecraft has used its

00:00:36,389 --> 00:00:33,680
instrumentation to map the asteroid from

00:00:46,549 --> 00:00:40,719
analyzing the data scouring bennu's

now with just months to go before sample

00:00:55,570 --> 00:00:51,360
collection the team has narrowed its
