* "The Gravity Probe-B Bailout," a feature article for IEEE Spectrum in Oct. 2008 print issue: Perhaps the most sophisticated satellite ever flown was nearly doomed by a tiny error, and NASA planned to end the experiment. But with a little creative fund-raising, the project may have bought enough time to prove its worth.
This feature story, for IEEE Spectrum magazine (Oct. 2008), provides an insider perspective on a latter day Apollo 13-style success story at NASA, over the troubled satellite Gravity Probe B, one that puts Einstein's theory of General Relativity to experimental test. The relativistic effects GP-B tested required marshaling the latest in cutting edge electronics, cryogenics, nanotechnology and aerospace technologies. All the more challenging, then, when they went awry and mission scientists had to wring the most out of the orbiting craft's faulty instruments without ever leaving the ground.
Postscript: In 2011, the NASA investigators behind GP-B held a press conference announcing that Einstein had once again stood up to experimental challenge. GP-B was a success, and a hard-earned one at that.
