Later, Uranus: New Horizons Passes Another Planetary Milestone
March 18, 2011
 
New Horizons is ready to put another planet - or at least the planet's
orbit - in its rearview mirror. The Pluto-bound spacecraft crosses the
path of Uranus around 6 p.m. EDT on March 18, more than 1.8 billion
miles from Earth.

"New Horizons is all about delayed gratification, and our 9 1/2-year
cruise to the Pluto system illustrates that," says Principal
Investigator Alan Stern, of the Southwest Research Institute. 'Crossing
the orbit of Uranus is another milepost along our long journey to the
very frontier of exploration."

New Horizons is headed for a rendezvous with planet Pluto and its three
moons in July 2015 and, soon after, possible encounters with smaller
bodies in the distant Kuiper Belt. The fastest spacecraft ever launched,
New Horizons has already covered serious space since lifting off in
January 2006 - traversing 20 times the distance between Earth and the
sun, including a flight through the Jupiter system
<http://pluto.jhuapl.edu/news_center/news/100907.php> in 2007 for a
gravity-assisted speed boost and scientific observations of the giant
planet and its largest moons.

"This mission is a marathon," says Project Manager Glen Fountain, of
the Johns Hopkins University Applied Physics Laboratory. "The New
Horizons team has been focu sed on keeping the spacecraft on course
and preparing for Pluto. So far, so good, and we are working to keep
it that way".

No pictures of Uranus are planned - the gas giant is 2.4 billion miles
from New Horizons and the spacecraft is currently in electronic sleep
mode - but the mission team on Earth is busy enough, putting final
touches on its Pluto-encounter plan and, in April, starting a search for
potential flyby targets in the Kuiper Belt. Preparations are also under
way for the annual spacecraft systems checkout this spring.

Next planetary milestone on New Horizons' voyage is the orbit of
Neptune, which it crosses on Aug. 25, 2014 - exactly 25 years after
Voyager 2 made its historic exploration of that giant planet.
