Title
Explorer XVII Satellite
Full Description
Weighing 405 lbs. (184 kg), this 35-inch (89-cm) pressurized
stainless steel sphere measured the density, composition,
pressure and temperature of Earth's atmosphere after its launch
from Cape Canaveral on April 3, 1963. The mission was one of
three that Goddard Space Flight Center specifically conducted to
learn more about the atmosphere's physical properties?knowledge
that they ultimately used for scientific and meteorological
purposes. Explorer XVII carried two spectrometers, four vacuum
pressure gauges and two electrostatic probes. Before it reached
its intended orbit that ranged from 158 to 570 miles (254-917
km) above Earth, the satellite was spun up to about 90 rpm.
