Outbound for the Frontier, New Horizons Crosses the Orbit of Mars

New Horizons' trailblazing journey to the solar system's outermost frontier
took it past the orbit of Mars today at 6 a.m. EDT (1000 UTC), 78 days after
the spacecraft launched.

At the time, because of Mars' position in its orbit, New Horizons was
actually closer to Earth than to Mars — just 93.5 million kilometers (58.1
million miles) from home, compared to 299 million kilometers (186 million
miles) from the red planet. Speeding away from the Sun at 21 kilometers
(about 13 miles) per second, the spacecraft crossed Mars' path some 243
million kilometers (151 million miles) from the Sun — close to the farthest
point in Mars' elliptical 687-day orbit.

New Horizons reaches its next planetary milestone on February 28, 2007, when
it makes its closest approach to Jupiter. Unlike the distant Mars passing
today, the Jupiter encounter will be at close range, allowing New Horizons to
make important scientific observations and to test procedures for its Pluto
encounter in 2015. Additionally, New Horizons will use Jupiter's powerful
gravity to boost its speed and adjust its course toward Pluto and the Kuiper
Belt.
