Sentinels of the Heliosphere

What NASA calls its 'Heliophysics Observatory' is an impressive fleet of spacecraft designed (often with international partnership) to study the relationship between the Sun, Earth, and Solar System. Flying in an array of trajectories and orbits, many of these satellites do not take images in the conventional sense but record fields, particle energies and fluxes in situ to give mankind a better understanding of space weather and space environments.

Wow! One of the best vids NASA TV has put out. Five stars. Thanks.

We need more Voyager-like missions. With our current technology, we could do it much better.

Same here. I send this out to people I know.

I live in England and postage to NASA in America has risen sharply. But I'll tell you how to do it.

Download a free program called "Ultraget" from the web. With this handy little app you can copy ANY YouTube video into your documents. It has a built in viewer so you can watch it at any time. You can then copy said video onto the medium of your choosing and post it direct to Barack Obama's secretary.

I love and enjoy this video so much that this is probably the 15th time I've watched it now:D

amazing!!! i love it!!

I agree - this is NASA at its best. Their PR is out of step with their achievements. People (i.e. the US taxpayer) need to know that it IS money well spent.

Excellent video! Facinating to see the orbits and their animations.

Someone who knows how, please send a copy of this to the White House! This is what NASA does so well; and support must be there to continue this kind of work.

I'm sending a copy of this to each of my GA Legislators! Please do the same for your House and Senate Representatives.

Thanks NASA.....

What An Interesting Video !!!

Keep Them Coming !!!

NASA would get a lot more funding if they just produced more videos like this so the general public understood the mission and point.
