Washington, D.C. – A year ago, Pluto was just a bright speck in the cameras of NASA’s approaching New Horizons spacecraft, not much different than its appearances in telescopes since Clyde Tombaugh discovered the then-ninth planet in 1930.
But this week, in the journal Science, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby.

Washington, D.C. – From possible ice volcanoes to twirling moons, NASA’s New Horizons science team is discussing more than 50 exciting discoveries about Pluto at this week’s 47th Annual Meeting of the American Astronomical Society’s Division for Planetary Sciences in National Harbor, Maryland.
“The New Horizons mission has taken what we thought we knew about Pluto and turned it upside down,” said Jim Green, director of planetary science at NASA Headquarters in Washington. “It’s why we explore — to satisfy our innate curiosity and answer deeper questions about how we got here and what lies beyond the next horizon.”
Washington, D.C. – Styx – also the faintest of Pluto’s five moons – was discovered using the Hubble Space Telescope in 2012, when New Horizons was more than two-thirds into its voyage to Pluto.
The Styx images downlinked on October 5th, 2015, were taken by the Long Range Reconnaissance Imager (LORRI) on July 13th, approximately 12.5 hours before New Horizons’ closest approach to Pluto.«Read the rest of this article»

Washington, D.C. – Icy mountains on Pluto and a new, crisp view of its largest moon, Charon, are among the several discoveries announced Wednesday by NASA’s New Horizons team, just one day after the spacecraft’s first ever Pluto flyby.
“Pluto New Horizons is a true mission of exploration showing us why basic scientific research is so important,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington. “The mission has had nine years to build expectations about what we would see during closest approach to Pluto and Charon. Today, we get the first sampling of the scientific treasure collected during those critical moments, and I can tell you it dramatically surpasses those high expectations.”
Washington, D.C. – NASA’s New Horizons mission has answered one of the most basic questions about Pluto—its size.
Mission scientists have found Pluto to be 1,473 miles (2,370 kilometers) in diameter, somewhat larger than many prior estimates. Images acquired with the Long Range Reconnaissance Imager (LORRI) were used to make this determination. This result confirms what was already suspected: Pluto is larger than all other known solar system objects beyond the orbit of Neptune.

Pasadena, CA – What’s icy, has “wobbly” potato-shaped moons, and is the world’s best-known dwarf planet? The answer is Pluto, and NASA’s New Horizons is speeding towards the edge of our solar system for a July 14th flyby.
It won’t be making observations alone; NASA’s fleet of observatories will be busy gathering data before and after to help piece together what we know about Pluto, and what features New Horizons data might help explain.

Washington, D.C. – If you lived on one of Pluto’s moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA’s Hubble Space Telescope shows that two of Pluto’s moons, Nix and Hydra, wobble unpredictably.
“Hubble has provided a new view of Pluto and its moons revealing a cosmic dance with a chaotic rhythm,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate in Washington. “When the New Horizons spacecraft flies through the Pluto system in July we’ll get a chance to see what these moons look like up close and personal.”

Washington, D.C. – Exactly 85 years after Clyde Tombaugh’s historic discovery of Pluto, the NASA spacecraft set to encounter the icy dwarf planet this summer is providing its first views of the small moons orbiting Pluto.
The moons Nix and Hydra are visible in a series of images taken by the New Horizons spacecraft from January 27th-February 8th, at distances ranging from about 125 million to 115 million miles (201 million to 186 million kilometers). The long-exposure images offer New Horizons’ best view yet of these two small moons circling Pluto which Tombaugh discovered at Lowell Observatory in Flagstaff, Arizona, on February 18th, 1930.

Washington, D.C. – In July 2015, NASA will discover a new world. No one knows what to expect when the alien landscape comes into focus. There could be icy geysers, towering mountains, deep valleys, even planetary rings.
At this point, only one thing is certain: Its name is Pluto.
On July 14th, 2015, NASA’s New Horizons spacecraft will make a close flyby of that distant world.

Washington, D.C. – One of the fastest spacecraft ever built — NASA’s New Horizons — is hurtling through the void at nearly one million miles per day. Launched in 2006, it has been in flight longer than some missions last, and it is nearing its destination: Pluto.
“The encounter begins next January,” says Alan Stern, of the Southwest Research Institute and the mission’s principal investigator. “We’re less than a year away.”
