Four and a Half Hours by the Speed of Light

From the NYT

That’s how long New Horizon’s information packet will take to reach all of us (minus a few on the International Space Station) on Earth.

That is at the speed of light which is 670,616,629 miles per hour.

It took the New Horizons spacecraft 9 years to travel the 3 billion miles.

All this (mostly) to do 22 hours of work.

We lost contact with New Horizons at 8:17 PM PST last night and it won’t be until 1:20 PM PST this afternoon until the spacecraft will send “a message it survived and a brief summary of how the day went” (NYT).

It will take 4.5 hours to receive that message.  Expect to hear about it then at about 5:50 PM.  Bon Chance inanimate spacecraft.
