Goddard Glossary: Gravity Assist: Video Description

Narration:

Transcript:

0:00 A woman in a NASA Goddard t-shirt talks in front of a conceptual space background. The words "gravity assist" are spelled out phonetically above her head.

0:20 Two stacked animations. The top one shows one of the Voyager spacecraft approaching Uranus. The bottom shows the Parker Solar Probe spacecraft in front of the Sun.

0:24 Back to the woman talking.

0:27 Animated orbital lines against the black of space. One is labeled Venus, and one is labeled Parker Solar Probe. They intersect, and Parker continues on an elliptical orbit back in toward where it started.

0:35 Animation of the OSIRIS-REx spacecraft approaching Earth. The camera follows the spacecraft's perspective, zooming in along Antarctica, and then back out into space.

0:45 Fade back to the woman talking.

0:50 Another animation of orbital paths. One is labeled Lucy and one is labeled Earth. Lucy's orbit meets Earth's and swings back out in a different direction.

0:56 Fade to animation of a Voyager spacecraft approaching Jupiter.

1:01 Fade back to the woman talking.

1:03 Animation of Earth with a dot labeled Lucy, approaching along an illustrated orbital path. Earth spins into a nighttime view, while the Lucy dot swings along the northern hemisphere and then back out into space.

1:08 Fade back to a top-down view of several colored orbital paths. An orbit the same color as Lucy in the previous animation is somewhat elliptical. It intersects with a green circular orbit and then swings back out further into the solar system.

1:15 Fade back to the woman talking.
