Gravity Probe B: Good Money after Bad?

Gravity Probe B scores ‘F’ in NASA review, New Scientist

“A NASA review appears to spell the end for Gravity Probe B, the project conceived in the 1960s to measure how the Earth warps the fabric of nearby space-time. A panel of about 15 experts commissioned by NASA analysed the performance of 10 NASA astrophysics missions that are currently operating in Earth orbit. A copy of the “senior review” obtained by New Scientist concludes that extending the lifetimes of the top nine missions “would be certain to deliver unique data of high scientific value”. But Gravity Probe B didn’t make the cut because the panel doubted further analysis of its results would yield significant new information.”
