American all-solid orbital launch vehicle. Solid-fuel, light payload, lower-cost launch vehicle developed by the Air Force and NASA in the late 1950's and used in a variety of configurations over thirty years. Launched from Cape Canaveral, Vandenberg, Wallops Island, and from Italy's equatorial San Marco platform off Kenya. Italy studied but did not develop subsequent upgraded versions.

AKA: SLV-1. Status: Retired 1994.

The Scout was a four-stage, solid-fuelled rocket developed to provide the United States with a reliable, versatile and cost-effective launch vehicle for a variety of space exploration tasks - orbital, high altitude probe, and high speed re-entry. Developed by NASA, the vehicle was produced by LTV Aerospace's Missiles and Space Division, which also provides systems management. The first US solid-propellant rocket capable of placing payloads in orbit, Scout had important roles in the space programs of NASA and the Department of Defense plus those of the United Kingdom, Italy, France, Germany and the 10-nation European Space Research Organisation (ESRO). Scout was launched in the United States from NASA's Wallops Island, Virginia, and by Air Force crews from the Western Test Range in California. A third site - the Italian San Marco sea-based platform off the east coast of Africa-made possible launches along the equator. Early Scouts were capable of boosting less than 150 kg into a nominal 500-km orbit. Performance was increased by development of a fifth stage velocity package. Prime Contractor: LTV Aerospace Corporation, a subsidiary of Ling-Temco-Vought, Inc. Associate Contractors: Aerojet General (first stage); Thiokol Chemical (second stage); Hercules Powder Company (third stage); United Technology Center (fourth stage); Honeywell (guidance).

    When the high-voltage power supplies were first turned-on, intermittent high-voltage breakdowns occurred, and the beam power supply became inoperative. Post-flight examination of the power supply indicated the high-voltage breakdowns were probably caused by pressure buildup in the primary propulsion unit due to gas vented from the spacecraft batteries. The primary propulsion unit high voltage section was not adequately vented to keep the pressure low enough. Engine thrusting was not accomplished in this test.

    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.

  • Ion Engine Test B Technology mission - . Nation: USA. Agency: USAF. Apogee: 2,000 km (1,200 mi).

    The first successful ballistic flight test of a cesium ion contact engine was conducted on a Scout booster launched from Vandenberg. Built by Electro-Optical Systems Corporation under an Air Force contract, the engine was the first of its kind to operate in space. The launch was designed to provide about 30 minutes of flight above an altitude of 370 km. At seven minutes into the flight the engine was operated with ion beam extraction. Full beam current of 94 mA was achieved about 10 minutes later. During the course of engine operation, an electric field strength meter was used to infer payload floating potential relative to space. Spacecraft potential was about 1000 V negative during most of the engine operation with the filament neutralizer. The absolute value of payload potential was about ten times higher than anticipated, and it was suspected that there was inadequate neutralization of the ion beam. The contact ion engine operated for 19 minutes until spacecraft reentry into the atmosphere. In addition to withstanding the environmental rigors of space flight, the ion propulsion system demonstrated electromagnetic compatibility with other spacecraft subsystems and the ability to regulate and control a desired thrust level.

    In this test, an additional wire neutralizer was incorporated and was immersed in the ion beam to provide a higher probability of adequate neutralization. The contact ion engine only achieved about 20% of full-thrust before reentry into the atmosphere. The short test time was due to a very short burn of the Scout vehicle's third stage. The high voltage was applied to the engine 7 minutes into the flight when the altitude was 490 km. Engine operation ended after 4 minutes when the altitude was only 80 km.
