Abstract:
When commanded to switch on, TWTA No. 1 on Viking Lander 2 failed to produce an S-band RF downlink, probably due to RF breakdown of the high-voltage power converter. High-voltage circuits designed to operate within the Martian atmosphere require special design precautions, such as insulation from ground potential, to avoid corona or other forms of high-voltage breakdown.
