Transcript:

0:00 A woman wearing a maroon NASA shirt talks in front of a greenscreen backdrop of gray regolith. The word chirality is spelled out phonetically above her.

0:07 A 3D structure of an amino acid zooms back to become part of a protein.

0:11 Three stacked clips show phytoplankton under a microscope, purple flowers, and running giraffes.

0:13 Back to the woman talking.

0:19 Two hands, palms down on a box, seen from above. They cross, so one hand is stacked on top of the other. Although most of the fingers more or less line up, the thumbs are sticking out in opposite directions.

0:26 Two stacked pictures of gloved hands slide in from opposite directions. In each, a 3D molecule model is superimposed. The top glove is holding L-Alanine. The bottom is holding D-Alanine. These are the same molecular structure but oriented differently.

0:29 Back to the woman talking.

0:43 Flying through space, past the Sun, past Earth, the asteroid belt, and Jupiter.

0:55 OSIRIS-REx’s sample container is seen from the spacecraft’s perspective as it blasts rocks up into the container.

0:58 Animation of a large white and red parachute falling over the desert, with a small black capsule suspended.

0:59 A gloved hand holds up a small vial with dark gray liquid.

1:02 Fade to the black regolith of the Bennu sample.

1:04 Back to the woman talking.

1:16 Looking down at the sample capsule full of regolith.

1:18 A tiny vial with a small pile of dark gray regolith.

1:19 Two tiny Bennu rocks seen under a microscope with bright white veins.

1:21 Back to the woman talking.
