NASA knew Mars Polar Lander doomed United Press International

The disappearance of NASA’s Mars Polar Lander last December was no surprise to space officials, UPI has learned. Prior to its arrival at Mars, a review board had already identified a fatal design flaw with the braking thrusters that doomed the mission, but NASA withheld this conclusion from the public. The probe was lost while attempting to land near the martian south pole on December 3.
