The 99.6-kilogram (220-pound) British-built UK-4satellite
structure is physically practically identicalto Ariel 3.
Its shape is cylindrical wir- a conical top structure.It has six major subsystems: structure, attitude control,solar-cell arrays, power supply, data handling, and radiofrequency subsystem fo r telemetry and command functions. Themain structure is made from fabricated aluminum alley.
Four solar-cell arrays, folded during the launch phase,protrude from the main body of the satellite. Four shortantennas are affixed to its conical top, and two slim, longbooms are extended from the conical structure, after orbitis achieved.
Its space battery system consists of 12 ceramic nickel-cadmium cells.
The data handling system consists of a high speedencoder, a low speed encoder and taDe recorders, a program-mer, and a command pulse conditioner. This system is iden-t ical to that flown on Ariel 3. Telemetry transmissions willoperate in the 136 to 13' MegaHertz (MIz) band.
1 . Ralo Noise Measurements. Provided by Jodrell Bank'Obervatoryof the University of Manchester (Prof. F. G. Smith)
In collaboration with the Science Research Council's Radio andSpace Research Station. A set of receivers measures galactic
noise in the MHz bands using two 6-meter (19.6-foot) mono-poleantennae located in the conical portion of the satellitewhich are d-ployed after orbit is achieved.
2. Electron Density and Temperature Measurements. Pro-vided by Birmingham University with Prof. J. Sayers as theprincipal investigator. The instrumentation is an improvedversion of the electron density and temperature sensor flownon Ariel 3.
3. Very Low Frequency/Extremely Low Frequency (VLF/ELF)Emission Measurements. Provided by Sheffield University, withDr. K. Bullough, as principal investigator, is an improvedversion of a *similar experiment carried onboard Ariel 3.Its range
has been increased by the addition of additionalreceivers to cover a wiler portion of the spectrum.
4. Very Low Frequency Impulse Measurements. Providedjointly by Sheffield University and the Science ResearchCouncil, the device employs an impulse counter to count VLFimpulses. It uses the same receivers as the VLF/ELF experi-ment.
5. Low-Energy Charged Particle Measurements. Providedby the University of Iowa, with Dr. L. A. Frank as principalinvestigator, the Low Energy Proton and Electron DifferentialEnergy Analyzer (LEPEDEA) is designed to measure the energyof protons aid electrons in the energy range of from fiveelectron volts to 50,000 electron volts, and their temporal
and angular distribution. It employs an array of electro-statis analyzers, two analyzers each fo r proton and electronintensities and a series of continuous channel multipliers.
Scout is NASA's only solid propellant launch vehiclewith orbital capacity. The first development Scout was
launched July 1, 1960 The UK-4 mission will be the 78thScout launch. Since the Scout was recertified in 1963, thelaunch vehicle has attained a 94 per cent success record.
Scout is a four-stage solid propellant rocket system.The launch vehicle and the spacecraft will be set on aninitial launch azimuth of 90 degrees.
The four Scout motors -- Algol II, Castor II, Antares II,and Altair III -- are interlocked with transition sectionsthat contain guidance, control, ignition, and instrumenta-tion systems, separation mechanisms, and the spin motorsneeded to stabilize the fourth stage. Control is achievedby aerodynamic surfaces, je t vanes and hydrogen peroxide jets.
The launch vehicle is approximately 22.25 meters (73feet) long and weighs about 17,144 kilograms (38,000 pounds)at liftoff.
The Scout Program is managed by NASA's Langley ResearchCenter, Hampton, Va. The launch vehicle is buil t by LTVAerospace Corp., Dallas, Tex.
