The private effort to reactivate ISEE-3, a 1970s NASA spacecraft in orbit around the sun, has successfully detected the spacecraft.

Unfortunately the signal is a little weaker than we expected, and it’s also odd that it fades out toward the end of this capture (it returns and fades in subsequent ones too). Again, this is all very preliminary data done tonight on a rush basis. Much more detail to follow.

They don’t have a lot of time to detect, re-establish contact, and get the spacecraft into the necessary orbit for research. Orbital mechanics give them only through July to do this before it will be too late.

    Maybe its tumbling and the transmitter is going from pointing at earth to pointing away.
