Lost and spaced?
Polar Lander's apparent loss on Dec. 2 comes less than three months after the $125 million Mars Climate Orbiter burned up in the Martian atmosphere. Hey, Orbiter was supposed to look at the atmosphere, not get intimately involved with it!.
NASA blamed the earlier snafu on a simple confusion of metric and English measurements. "People sometimes make errors," said Edward Weiler, NASA's associate administrator for space science. "The problem here was not the error, it was the failure of NASA's systems engineering, and the checks and balances in our processes to detect the error. That's why we lost the spacecraft."
Why do we hear an echo of a baffled eighth grade science student: "Feet? I thought you meant meters!"
But that's not all, folks. In 1993, the $1 billion Mars Orbiter went AWOL as it approached Mars.
With three Mars probes totally kaput, we figure agency administrators ought to start channeling with experts on losing streaks at Las Vegas mental-health clinics or bars around Wrigley Field, home of the Chicago Cubs.
Though NASA successfully put a rolling breadbox on the surface of the Red Planet in 1997, the recent failures have us Why Filers muttering darkly about the ability of Martians to repel Earthly invasions. Did they really invent star wars? Or should we attribute the problems to a shortage of rocket scientists on Earth?
On a more serious level, the snafus stress that exploring space is a dangerous and tricky business. In 1986, a bad seal exploded the Space Shuttle Challenger's rocket booster, killing seven. In 1971, three cosmonauts died on a Soviet spaceship after their air leaked out. Here's a chilling write-up of these disasters.
Problems of various sorts are standard issue for spaceflight, but there are often ways to work around them. Galileo, for example, reached Jupiter with only its bitty antenna working -- the bigger one got snagged like a fishing lure on a tree stump as it was being unfurled. The upshot was a constricted flow of data back to Earth, but not a disaster.
As the Martian morass shows, however, some space disasters utterly resist repair. The problems can stem from navigators who don't know a meter from a mile -- and with simply running out of fuel. Then there are those pesky swarms of space junk travelling at a bejillion miles a second and radiation storms caused by weird blips in the Earth's magnetic field.
Heading for space? Then heed the wise sergeant in in Hill Street Blues who instructed the cops setting out to fight for law and order in the city streets: "Hey hey hey hey! Let's be careful out there."

What pickled Polar Explorer?
