How do they send signals to it? 

Might be a simple question but I don't understand how the craft is connected to a computer.

I would probably still figure this out before accurately answering an algebraic equation.

I believe they prefer to be called little planets.

Pretty close. I don't know if they're using SMS but it's the basic idea.

It blows my mind that it takes 248 years for pluto to orbit the sun, but there is still enough pull that many miles away to keep it in orbit. Why wouldnt the planet (eh former planet) just float out into the kuiper belt.



This doesn't really answer your question, but it was always one of my favorite videos that helped describe our suns gravitational pull.

I love how we can find a planet 100 million light years from earth that "could" sustain life...but we can't find frickin Pluto? We've only been following it for last 100 years.

It won't be long, once the mission is a success and it is all over the news, we won't be able to call it a dwarf planet anymore. Too many people will be offended.

Nobody has found a planet that far away. Most exoplanets are on the order of 100 to 1000 ly away, not 100 million.

And we know their locations with *much* less precision than we know Pluto's location. We basically just know they're out there, not precisely enough to guide a probe even if we could send one that far.

Thats a great demo. Answers questions i have not understood. Especially on way everything in our system orbits the same direction and how our moon orbits us while we orbit the sun.

Sad at the end he has to talk about the theory of relativity not being part of the star test, and to do the demo after the state test prep. Teaching to a test is so stupid.

My 9 yo nephew's life mission is to correct the grave injustice of Pluto being declassified as a planet. There's no better way to get him riled up than saying something like "Pluto? That ole non-planetary hunk of ice. Pfffft."

Yeah, it's interesting that this probe was launched before global warming became NASA's primary mission. Given how cold Pluto is I doubt they'd even bother to launch it now.
