SO COOL--DID YOU KNOW THIS?

While @NewHorizons2015 flies across, it is serving as an observatory, observing dozens of Kuiper Belt Objects-- small and large-- using its LORRI telescopic imager! Look at all these objects we're studying in ways you cannot from Earth! #SO_PROUD! pic.twitter.com/Sozw0miE4n

RIGHT THIS MINUTE, NASA’s @NewHorizons2015 spacecraft is firing its engines out in the Kuiper Belt to home in on our next flyby target!! That target is an ancient world called Ultima Thule. This engine burn is the farthest ever made by any spacecraft. ULTIMA, HERE WE COME! pic.twitter.com/qAd3nPzgYj

BREAKING…Signal has just been received at mission control, New Horizons has successfully started its flyby program of stored commands and the exploration of Ultima Thule 4 billion miles away! THIS IS IT FOLKS, FLYBY HAS BEGUN! Go New Horizons!! #NASA #Science #SPACE#ULTIMAFLYBY pic.twitter.com/48VuCLHz5i

PINCH ME! We’re less than 6 days from the flyby of #UltimaThule ! Just half an hour ago it should have entered Encounter Mode, a state preventing anomalies from diverting off the flyby plan. Confirmation of that critical event comes this afternoon—from 4 billion miles away. 1/2 pic.twitter.com/1flkuE1NN2

Later today-- just over 100 hours to Ultima! The spacecraft has entered it's battle hardened :"Encounter Mode" and is already returning data about Ultima and its environment.

Enjoy this best wishes video to our team from rock star scientist and science author, David Grinspoon! pic.twitter.com/2P9a5rMZJt
