(upbeat music)
(man mumbles)
- Yes.
- Guys, guys, I need you to be quiet though,
in the other room.
- Okay.
- Okay, got it.
(man mumbles)
- Okay, we're doing it.
(instrumental music)
- Pretty much anything that you can observe on the land
and coast and sometimes even in the ocean,
NISAR will have an application.
Very exciting mission,
generating an enormous amount of data
that will keep the science community
and the applications community busy for a long time.
- NISAR is a partnership mission between NASA and ISRO,
the Indian Space Research Organization.
It's a collaborative project.
- And we'll be collecting data
for all around the whole earth
for all of the landmasses.
- Looking at volcanoes, earthquakes, landslides,
other natural hazards that occur in the crust of the earth.
- And movement of sea ice, movement of glaciers,
how much forest land is growing or being reduced.
- Because it can image at night and through clouds,
It can allow us to see through storms.
- It's really gonna allow us to see things changing
in areas where we can't with other satellites.
- NISAR is going to open our eyes
to the potential of this technique for seeing the ground
in places that otherwise has been obscured.
- So every 12 days we will map the landmasses
and then we can take those mappings and we can compare them.
We can do what we call interferometry.
- Where we can take an image acquired on one day
and combine it with an image acquired 12 days later,
from that same vantage point,
looking at the same point on the ground.
And when we do that,
we can see the motion of the ground down
to a fraction of the radar wavelength,
which in this case is on the order of a few millimeters.
- NISAR has two radars on it.
Two synthetic aperture radars,
one is an L-band and the other is an S-band.
- So it's kind of the Tesla or the Maserati of radars,
whichever you think is cooler I guess.
- This here's the radar payload, that is the spacecraft bus,
large 12 meter reflector common in Tennessee system for both
L-band and S-band to send out the RF signal
and capture the return signal.
- Good morning (indistinct)
- (indistinct) how are you today?
- I am fine.
- The pandemic is something that we were not counting on
when we developed this project.
- The NISAR Project was actually pretty well vast
with this remote operations
because of the Indian engagement.
- It was a little bit of a WebEx fatigue,
but I think we're learning how to do it better now.
- But yeah, we're all in great spirits
and we will take a little hit to the schedule,
but we've been waiting a long time for this mission
and we wanna do it right.
- We want the hardware to work.
And we want the science to be done.
- One of the best things we can do
to increase diversity in the sciences
is to make it easier for people to enter the sciences.
- For the data is gonna be freely available to everybody,
We aren't gonna have to pay for it like we do
with some satellites.
- So making the data free,
having it easy to download to your own machine,
all of that stuff is critical
if we want to remove those barriers to entry to the field.
- I'm looking forward to the sense of discovery
that I think we're going to have
when NISAR data start coming down.
- All science is incredibly important to understand
what's going on in the name of what our children
and grandchildren are gonna have to face in the future.
And all the information we collect now
is only gonna help them understand that better
and hopefully make their lives better.
- Digital, electronic subsystem cognizant.
There it goes by (indistinct)
- You know, the radar will
- I can't recall
There we go.
- That's our real life here in 2020.
