Thanks to NASA's New Horizons spacecraft, we're about to see Pluto up close for the first time. Here are a few snapshots of the scientists and engineers who'll make it possible.

After a 9½-year, 4½-billion-mile journey, NASA's New Horizons spacecraft is on the threshold of its historic encounter with Pluto and its moons. The spacecraft will be its closest to Pluto, just 12,500 km (7,800 miles) away, at 11:49:58 Universal Time on July 14th.

Emily Lakdawalla's 8-page preview article in the July issue provides all the info you'll need to prepare for the flyby, and don't forget to read principal investigator Alan Stern's exclusive commentaries on the mission for

Of course, it's taken hundreds of scientists and engineers to get New Horizons to its destination, and we thought you might enjoy seeing a few snapshots of them hard at work. If you want to see more images about the New Horizons mission, Pluto, and related topics, visit Pluto Picture of the Day.

New Horizons in NASA clean room
Technicians look over the New Horizons spacecraft in the clean room at Kennedy Space Center's Payload Hazardous Servicing Facility prior to its launch in January 2006.
LORRI installed on New Horizons
LORRI, short for Long Range Reconnaissance Image, provides the spacecraft with powerful telescopic eyesight. It consists of a telescope with an 8.2-inch (20.8-cm) aperture and a 2.63-m focal length.
Clyde Tombaugh goes to Pluto
A small container of ashes from Clyde Tombaugh, who discovered Pluto in 1930 and died in 1997, is affixed to the inside, upper deck of the spacecraft.

Burning the contingency launch plan
Following tradition, the contingency plans developed to deal with a possible rocket failure are ceremonially burned 6 hours after New Horizons' successful launch on January 19, 2006.

New Horizons' complex wiring
All these wires connect different instruments and electronics aboard the New Horizons spacecraft, so that their results can be sent back to Earth via the main radio antenna.

Frozen Plutonian air
Pluto's atmosphere is 97% nitrogen. But it's so cold there, with surface temperatures around 44 K (–229°C), that nitrogen (melting point: 63.15 K or –210°C) can exist as solid ice on its surface.

New Horizons is not the first mission proposed to visit Pluto. Scientists have been pushing NASA to go there since 1990.
