NASA | Magnetometry 101

NASA satellites use very sensitive devices called magnetometers to measure the magnetic fields of planets. Like very sensitive compasses, these devices can measure both direction and strength of planetary magnetic fields. Learn more about how magnetometry works!

local magnetic field o mars would love to learn more about them!

[akierrs2]

awesome vid as asual!

[dudekool12]

is he iron man?

@LebaneseNostalgia For a brief animation about the history of magnetic fields at Mars see: mgs-mager.gsfc.nasa.gov/animat­ion/mars_impact.html

@RovaRusty thats what i tought

[RovaRusty]

@TeenageIronman no

[adansagu]

These are awesome presentations given much thought and easy to understand. Three cheers for NASA grat !!!

is this a real hologram?

[darkembassymusic]

@goodintensions Its not a holographic computer, its computer effects (think FX used in the film: Minority Report). However you may be interested to learn that holographic technology has had a breakthrough only a few weeks ago. Look for a scientist named " Nasser Peyghambarian " on google :)

@MsWanderer1 And you seem to be a cranky old bitch, but things aren't always what they seem, are they. I'm Sorry I couldn't answer your question to your satisfaction, but I have a feeling you wouldn't be satisfied with any answer.

"you've probably used instrumentation that I've designed." Then why the dumb question? And who calls it 'the math'? "nice that you can regurgitate the physics text book", "did not even give me a text book answer"-- Which is it? Nobody here really cares, dear.

@julsHz

I've been using the math for over 50 years Julie. If you work in a science occupation then you've probably used instrumentation that I've designed.

It appears you got your degree by learning methodology; you sure didn't learn how to think now did you? The fact that you did not even give me a text book answer to my question makes me assume your degree is in the liberal arts.

You seem to be just another ignorant troll Julie!
