After waiting so long for this, it's hard to believe the time is finally here. Anxiously awaiting the all-clear signal in about 24 hours and all the pix and info to follow.

“Because Pluto is almost 3 billion miles away, it will take 4.5 hours of travel time at the speed of light for the all-clear signal to reach Earth.”
The speed of light, for those that don’t know, is 186,000 miles per second!

In a vacuum (like space). In other mediums (air, water etc.) it slows down slightly.

The craft will not be communicating with earth during the closest approach but will continue sending back data from it for months.
Its kind of cool keeping an eye on the real time simulation with NASAeyes. http://eyes.nasa.gov/

Too bad writers can’t relate to people well.
Pluto is: 2,370 kilometers (1,473 miles)
Our moon is: 1,737.10 km (wiki sucks too, can’t even show miles)
So it’s about 1/4 larger than our moon. Or 125% the size of our moon.

Thought I’d have some fun with this. Figures here were probably fudged a bit for easier understanding.
I calculate the time for light to travel here from 3 billion miles at 186,000 mps.
It actually works at as 4.48 hours, a smidgen more at 5 places.
This amounts to 72 seconds short of the 4.5 hours they mentioned.
During that extra 72 second, the message traveled 13,392,000 miles past earth.

3 billion miles...The speed of light, for those that dont know, is 186,000 miles per second! All of a sudden....that seems so slow.

This settles it. Time to make Pluto a planet again.

And our moon, at approximately 2100 miles across, is about 1/4 the diameter of Earth (~8000 miles in diameter) — about from New York City to Idaho. In other words, if the Earth was where the moon is, it would be 4 times as wide as the moon in the sky.

News writers rarely seem to be able to relate to people very well, especially with science-related subjects.
I’ve always been amazed that Pluto was even discovered. It’s so small and at the time it was discovered, we didn’t have the telescopes we have today.

Yeah, but only on the straightaways.
Lol! But light does actually "curve" around extremely massive objects due to gravitational effects. It's called "gravitational lensing".
