Nasa never ceases to amaze me, mad love and respect from Bangladesh!

With the current climate, earth science seems more vital than ever. Great work NASA.

Thanks for your work

Thank you!

Great! Strangely apt abbreviation name of Grace.

Superb video.

insightful

Beautiful music

The subtitles at 00:06 say "(MUSIC: A Moment in Time)". Are you sure it's a theme from "The Piano" soundtrack? I can't find any track with a similar name... Thanks. www.amazon.com/Piano-Michael-Nyman/dp/B0001FUHV6 en.wikipedia.org/wiki/The_Piano_(soundtrack) kzread.info/dash/bejne/rKR20dqLk73Worw.html

thank u from the biottom of my hert for trying to help,

I love science.

Fabulous summary, and indication of the value this sort of mission brings for all of us. Would it be possible to tell us what the music is please?

Get GRACE II in SPACE!!!! Don't let Drumpf stop it!

true anthem

Wow!!!

Is there an API one could use to get Data from the Grace Satellites over the time its been operational.

I want to see more

What's the name of the background music?

Better mirror these releases to a free country like Canada.

thats the problem, what water we get from the skies is not being absorbed, here in my city seems they buried some rivers, seeing how great planners they weere it breaks mt heart see see humaity not understand

If anyone get the reference

I've heard that the way the GRACE satellites measure the gravitational gradient of Earth is by having two satellites and measuring the shift of orbit of one satellite from the the other in terms of their distance. I get how the Sun wouldn't affect these satellites because it's too massive to have a significant change in gravitational pull. But what about the moon? Wouldn't the moon have a gradient greater than the Earth? So wouldn't it affect the distance of orbits more? Or is it too far to affect the satellites?

I think at the precision they are measuring they have to factor the sun AND its solar winds in. There is a huge amount of processing in the background to eliminate these errors.

out of fuel? why there is no solar cell on it?

maybe ion thruster, i know it is weak but being there for years it should be able to keep the satellite in orbit in long run... i do not know the math... but ok nasa definitely did think about that

Tony Wells Why would you need propellant in orbit? I don't get it...

While ion thrusters do have a much higher specific impulse, which saves on fuel weight, they also require a lot of power, which means bigger (and therefore heavier) solar panels, and their xenon has to be stored at quite high pressures, needing stronger tanks (so, heavier too). So, they are only worth it if you plan to use a lot of delta-v during the mission. But a similar mission, GOCE, used a spacecraft in a much lower orbit (250 km, probably the lowest I've heard of for any functioning spacecraft), therefore having a lot more atmospheric drag to deal with. And ESA did go for ion engines on that one.

This video is edited and going viral at this very moment. They say these are UFO's........ LOLLLL they gonna be surprised.

It is so sad that ignorance has control of your budget. I will miss NASA. I did not vote for trump and I do not support ignorance.

I don't have to prove it, l live it. Our islands are sinking...we've lost land to the ocean in the last 15 years. Some of the smaller islands had completely disappeared. You can debate and argue on the stupid data but we are living in the reality that one day we won't have a home.
