New Horizons Interview with Dennis Reuter

Dr. Leila Mays explains a space weather model that depicts conditions experienced by the New Horizons mission. Watch this video on the NASAexplorer YouTube channel.0 A few months before New Horizons was due to reach Pluto, a community of scientists came together to determine just what kind of a environment the mission would experience during its historic flyby.

A NASA spacecraft closes in on an unexplored neighborhood at the outskirts of the solar system. Watch this video to find out what New Horizons hopes to see when it arrives at Pluto in 2015. Pluto and its moons Charon, Nix and Hydra are seen in this image taken by the Hubble Space Telescope. New Horizons carries seven scientific instruments and weighs 1,060 pounds. New Horizons launched from Cape Canaveral, Florida, on Jan. 19, 2006. For More InformationSee [Science@NASA](http://science.nasa.gov/science-news/science-at-nasa/2011/03dec_newhorizons/)

Dust ground off icy bodies in the Kuiper Belt, the cold-storage zone that includes Pluto and millions of other objects, creates a faint infrared disk potentially visible to alien astronomers looking for planets around the sun. Neptune s gravitational imprint on the dust is always detectable in new simulations of how this dust moves through the solar system. By ramping up the collision rate, the simulations show how the distant view of the solar system might have changed over its history. More here.

For the first time, the models include the effects of collisions among grains.

In 2008, Hubble spotted a planet orbiting inside the ring. The bright central star is masked out so that the faint ring can be seen. Credit: NASA/ESA/P. Kalas, J. Graham, E. Chiang, E.
