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.
