Factoid: The microprocessor chip on New Horizons runs at 12MHz and costs 42,000 US dollars. It's based off the Mips R3000 and is almost a SOC; requiring only an interface to the spacecraft bus/instrumentation, and an array of ram chips.

New Horizons Web Site:
New Horizons Becomes Closest Spacecraft to Approach Pluto

December 2, 2011

NASA’s New Horizons mission reached a special milestone today on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft.

It’s taken New Horizons 2,143 days of high-speed flight – covering more than a million kilometers per day for nearly six years—to break the closest-approach mark set by NASA’s Voyager 1 in January 1986. Pluto wasn’t on Voyager’s mission path, but after making historic flybys of Jupiter in 1979 and Saturn in 1980, the intrepid probe came about 983 million miles (1.58 billion kilometers) from Pluto as it raced to the solar system’s outskirts.

How Close Is Close? In the expanse of space, the term "close approach" is relative. The closest spacecraft pass by Pluto before New Horizons was NASA's Voyager 1, which came within 983 million miles (1.58 billion kilometers) of the dwarf planet on Jan. 29, 1986. That's still 10.5757 astronomical units, or more than 10½ times the distance between the Earth and Sun!


Now New Horizons, which is healthy, on course and closer to Pluto than Voyager ever came, will continue to set proximity-to-Pluto records every day until its closest approach – about 7,767 miles (12,500 kilometers) from the planet – on July 14, 2015.

“We’ve come a long way across the solar system,” says Glen Fountain, New Horizons project manager at the Johns Hopkins University Applied Physics Laboratory. “When we launched [on Jan. 19, 2006] it seemed like our 10-year journey would take forever, but those years have been passing us quickly. We’re almost six years in flight, and it’s just about three years until our encounter begins.”

Pluto View (circa 2007): New Horizons’ current view of Pluto still resembles this image snapped by the spacecraft’s long-range telescopic camera four years ago; that will change exponentially beginning in late 2014, as New Horizons speeds closer and closer to its target planet and its cameras begin to resolve details.


From New Horizons’ current distance to Pluto – as far as Earth is (on average) from Saturn – Pluto remains just a faint point of light. But by the time New Horizons sails through the Pluto system in mid-2015, the planet and its moons will be so close that the spacecraft’s cameras will spot features as small as a football field.

“What a cool milestone!” says New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute. “Although we’re still a long way — 1.5 billion kilometers from Pluto — we’re now in new territory as the closest any spacecraft has ever gotten to Pluto, and getting closer every day by over a million kilometers.

“I wonder how long it will be until the next Pluto spacecraft — perhaps a future orbiter or lander — crosses this distance marker?” he continues. “It could be decades.”

Rare Space: New Horizons is just the fifth probe, after Pioneers 10 – 11 and Voyagers 1 – 2, to traverse interplanetary space so far from the Sun. And it's the first to travel so far to reach a new planet for exploration. Pluto is 3.1 billion miles (5 billion kilometers) from Earth.


New Horizons is currently in hibernation, with all but its most essential systems turned off, speeding away from the Sun at more than 34,500 miles (55,500 kilometers) per hour. Operators at the Applied Physics Lab will “wake” the spacecraft in January for a month of testing and maintenance activities.

In 4 years (or less), we'll get better pictures of Pluto than this:

Can't wait to see what Pluto really looks like! (rather than a couple of grey splotches on a sphere that is)

He's a nice diagram of the encounter with Pluto:

With mostly dirt and ice on the surface, I expect it would look a bit like one of Saturn's airless moons.

The body perhaps most similar to Pluto that has been imaged close-up is Neptune's moon Triton:



There are differences (as they're obviously different bodies entirely) but there could be some similarities.

Isn't there supposed to be a bit of an atmosphere out there on Pluto? A very tiny bit? So that would make it somewhat unique. And it is Pluto. When I heard about this mission I got very excited to finally get to see some real pictures, and see what it really looks like.

Still got some ways to go until then.

Darn. We've got to wait until 2015... But then we'll have some nice textures for Pluto.
