NASA’s New Horizons scientists have released papers that shed new light on the Pluto System

March 20, 2016 |

NASA Headquarters

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.

This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface. For example, scientists note a haze layer about 3 miles (5 kilometers) above the surface (lower left area of the image), which descends to the surface at the right.

NASA’s New Horizons spacecraft continues to make fascinating discoveries about Pluto

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.”

NASA’s New Horizons Spacecraft sends back first images of Pluto and it’s moon Charon

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.”

NASA’s New Horizons spacecraft answers decade old question, What is the Size of Pluto?

July 14, 2015 |

NASA Headquarters

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.

A portrait from the final approach. Pluto and Charon display striking color and brightness contrast in this composite image from July 11, showing high-resolution black-and-white LORRI images colorized with Ralph data collected from the last rotation of Pluto. Color data being returned by the spacecraft now will update these images, bringing color contrast into sharper focus. (NASA-JHUAPL-SWRI)

NASA’s New Horizons Spacecraft to be assisted by other missions during Pluto flyby

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.

NASA’s Hubble Space Telescope reveals chaotic wobbling dance of Pluto’s Moons Nix and Hydra

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.”

NASA’s New Horizons spacecraft one year away from reaching the dwarf planet, Pluto

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.

NASA’s New Horizons spacecraft nears it’s destination, the planet Pluto

January 16, 2014 |

Written by Dr. Tony Phillips
Science at NASA

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.”
