Everyone knows that NASA’s New Horizons spacecraft will make its closest approach to Pluto on 14 July 2015 at 11:50 UTC. But I wanted to know when I should start looking for the first images from that moment.
Distance from Earth to Pluto
33.71 AU = (1.49597870700 x 10^11 m) x 33.71
5.042944221297 x 10^9 km
Speed of Light
2.99792458 x 10^8 m/s =
1.0792528488 x 10^9 km/h
One-way signal from Pluto to Earth
4.672625351 hours (4 hr 40 m)

P.S. I really don’t like NASA’s standard web page template at all — the fonts are way too tiny for comfort and the narrow main window frame is oh so 90’s. Someone needs to introduce their web team to HTML5/CSS3 and Bootstrap, and soon.
