What is Veritas' mission? What is its profile?

1:00.0

What's great about these two missions is that we were in competition with each other.

1:03.7

I say we because I'm on DaVinci, which is the other mission. But we were in competition

1:09.3

fiercely because everybody wanted to have the next mission. And yet now that they've

1:13.8

selected both missions, we can work together and it's really a case of the whole being

1:18.5

much greater than the sum of the parts because these missions are complementary. In the

1:22.4

case of Veritas, it's an orbiter. The centerpiece of Veritas is a radar instrument that's much

1:32.6

more sophisticated than the Magellan radar instrument that we had in the 1990s. We'll

1:37.1

get much more detailed maps of the surface geology and geography. We'll be able to see

1:47.8

in great detail and we'll even be able to look for motion. So as this spacecraft orbits

1:54.0

and then it goes back over some of the previous places on the planet that it's previously

1:59.4

mapped, this radar instrument is so finely tuned and calibrated that they can even see

2:06.0

if there's been a little bit of differential ground motion in between the different orbits

2:10.9

which will help us understand not just what it looks like, but what level of activity

2:16.6

there may be there now on Venus. The whole mission for the name Veritas stands for Venus

Missivity, E-Messivity, Radio Science, Insar, Topography and Spectroscopy. Does that mean
