This Week at NASA: Pluto Amazes and we Look Back at Apollo-Soyuz.

After a nearly decade-long journey, NASA's New Horizons spacecraft arrived at Pluto on July 14 - passing by at a mere 7,750 miles above the surface ... resulting in an absolutely breathtaking image - the closest ever of Pluto.

Initial congratulations included a Twitter post from the White House ... and from iconic figures in the scientific community. The so-called "data waterfall" released by New Horizons contains so many astounding images and detailed information about Pluto that investigators anticipate it will take about 16 months to send it all back to Earth. Also, Mariner 4 Mars flyby anniversary, Newman sworn-in, New wildfire detection tool, Expedition 44/45 prepares for launch and 40th anniversary of Apollo-Soyuz.
