Gravity probe B is effectively dead, after having exhausted its superfluid liquid He and taking data for ~ 1 year. Current temperature now likely exceeds 10K and rising (beyond the superconducting critical temp of niobium) with drag-free orbit mode around the quartz gyros switched off. Data analysis begins now and is expected to be complete in one year.

Do you hear that huffing, chuffing sound? See those locomotives pulling all those tank cars?
