Orion Capsule Safely Recovered, Complete With 12-Year-Old Computer Guts

Lucas123 writes While NASA's Orion spacecraft, which blasted off on a successful test flight today, may be preparing for a first-of-its-kind mission to carry astronauts to Mars and other deep-space missions, the technology inside of it is no where near leading edge. In fact, its computers and its processors are 12 years old — making them ancient in tech years. The spacecraft, according to one NASA engineer, is built to be rugged and reliable in the face of G forces, massive amounts of radiation and the other rigors of space."Compared to the [Intel] Core i5 in your laptop, it's much slower — much less powerful. It's probably not any faster than your smartphone," Matt Lemke, NASA's deputy manager for Orion's avionics, power and software team, told Computerworld. Lemke said the spacecraft was built to be rugged and reliable — not necessarily smart. That's why there are two flight computers. Orion's main computer was built by Honeywell as a flight computer originally for Boeing's 787 jet airliner. Not only was the launch itself successful, but the sensor-laden craft's splashdown was smooth ("bulls-eye," as NASA puts it), and NASA has now recovered the capsule. ABC News has some good photos, too.

In fact, its computers and its processors are 12 years old

They word it like NASA is dumpster diving for its flight computers these days. The CPU may be from what was new 12 years ago, but I seriously doubt the physical unit is actually 12 years old.

It's also hardened against radiation. I would be willing to bet that any processor in these systems will still be functional long after most newfangled home CPUs are long dead. These flight computers will be remain functional in an extremely harsh environment longer than any home CPU would last. Even with how pampered home processors are in comparison.

Exactly.

Rocket science ain't ... uh... never mind. But it doesn't take a lot of computing power to navigate. But what it takes is computers that can withstand the stress. Extreme acceleration, radiation, possibly temperature changes, unreliable power supply and so on. When you only need one percent of the processing power of a modern CPU, you don't care about having only 10% of the current CPU power available. But it is very comforting to hear "works from 3-5V, logic accepts up to 6V on its I/Os without damage" instead of "if you're off by 0.2V, unpredictable behaviour might occur, be off by 0.5 and it's going poof".
