SERT 1 Technology mission - . Nation: USA. Agency: NASA. Apogee: 4,002 km (2,486 mi).
Suborbital 30 minute test of NASA SERT ion engine. The early part of the flight was dedicated to attempts to operate the cesium engine. The cesium engine could not be started because of a high-voltage electrical short circuit. The mercury engine was started about 14 minutes into the flight. This engine was successfully operated for 31 minutes with 53 high-voltage recycle vents which were handled by the fault protection system. Each of the recycle events was only a few seconds duration. Major results from the test were the first demonstration of an ion engine in space, demonstration of effective ion beam neutralization, no EMI effects on other spacecraft systems, and effective recovery from electrical breakdowns. Thrust was measured using three independent measuring systems, and there were no major differences between in-space and ground test performance.
