  • + Voyager 1 Apparently Attacked by Interstellar Dragon
    D. L. Chenette, NASA Headquarters, Apr. 01, 2014
    NASA's Director of Heliophysics announced that telemetry suddenly vanished today from Voyager 1, earlier reported to have emerged into local interstellar space, after a large thermal surge and the last message "Thar be Dragons!".
    A competing interpretation of the puzzling loss of signal suggests that Voyager actually fell off the edge of the heliosphere and descended into the netherworld below. Support for this interpretation came not only from the thermal surge but also the detection of anomalous sulphur ions just before its demise. These ions could only be detected at high energies since the spacecraft's low-energy plasma instrument has long been inoperative.
