00:00:00.683 --> 00:00:05.141
The science that we are looking at is geared at looking at hydrothermal systems on Earth

00:00:05.201 --> 00:00:12.901
as a means to explore or understand hydrothermal or other similar water-rock interactions on other systems in our Solar System.

00:00:12.961 --> 00:00:16.649
As you change the geology and the chemistry of these systems,

00:00:17.230 --> 00:00:21.444
then the microbiology at the base of the food chain of these systems changes as well.

00:00:22.698 --> 00:00:30.234
And so where that's taken us some new departure into this space research is really evolved only over the last two or three years.

00:00:37.158 --> 00:00:45.234
I'm Chris German from Woods Hole Oceanographic Institution and I'm going to be the science lead on our SUBSEA project exploration of  Lō`ihi Seamount.

00:00:45.732 --> 00:00:54.903
I'm Darlene Lim and I'm at the NASA Ames Research Center as well as the Bay Area Environmental Research Institute, and I'm the principal investigator of the SUBSEA Research Program.

00:00:55.801 --> 00:01:03.170
So in the last 20 years or so, NASA programs like the Galileo mission to Jupiter and the just-completed Cassini mission to Saturn,

00:01:04.171 --> 00:01:10.795
we've realized that there's moons of large planets of the Solar System that also have liquid water oceans. 

00:01:11.337 --> 00:01:16.431
In their case, they're covered with ice cap, but underneath that ice cap, there are deep saltwater oceans,

00:01:17.245 --> 00:01:20.885
and in at least two cases, those saltwater oceans are in contact with a rocky seafloor.

00:01:21.571 --> 00:01:28.218
So in our circumstance, we're actually looking at an inter-plate seamount that, in the first year, in 2018, we're headed to Lō`ihi.

00:01:28.936 --> 00:01:34.301
And this seamount is really exciting to us because it's not the kind of traditional exploration data point,

00:01:34.808 --> 00:01:43.137
it's a means, if you will, of not only ground truthing what we think we know, but also as a means to prepare ourselves for what we want to learn in the future,

00:01:43.197 --> 00:01:47.434
and actually impact future missions to other ocean systems in our Solar System.

00:01:47.494 --> 00:01:57.241
Enceladus, one of the moons of Saturn, the moon is so tiny that although the ocean is five or more kilometers deep, so really deep, even by Earth's standards,

00:01:58.132 --> 00:02:01.692
the pressures at the bottom are really just the same as a few hundred meters deep on Earth.

00:02:02.318 --> 00:02:07.525
So Lō`ihi Seamount, which rises up to shallow water depths, is a really cool place to go and study for that purpose.

00:02:09.245 --> 00:02:15.659
So it's a really cool time to be working in this area, that suddenly we realize that everything we've been doing with things like the Nautilus,

00:02:15.719 --> 00:02:17.995
learning how to use robots and go and explore the seafloor,

00:02:20.420 --> 00:02:28.929
is exactly the planning mission that NASA would have wanted someone to have been investing in in the last 50 years so they could now know how they could go and do that in the outer Solar System in the future.

00:02:29.725 --> 00:02:39.163
The architecture when it comes to telepresence is a wonderful model for future mission architectures when it comes to human space flight to deep space or to Mars.

00:02:39.732 --> 00:02:46.306
And so we're going to use all of these different sort of terrestrial means to learn about future opportunities when it comes to 

00:02:46.366 --> 00:02:53.320
getting ourselves into a position to do robotic exploration on other planets or else human exploration on other planets as well.
