Title
OSO Launch
Full Description
NASA successfully launched more than 200 Earth-orbiting satellites, including
Goddard's eighth Orbiting Solar Observatory aboard this Delta rocket on June
21,1975, at Cape Canaveral, Florida. The satellite-the final in a series of
spacecraft specifically designed to look at the Sun in high-energy wavelength
bands that scientists cannot see on Earth-gathered data on energy transfer in
the Sun's hot, gaseous atmosphere and its 11-year sunspot cycle. Sunspots are
cooler regions that appear as dark patches in the visible surface of the Sun and
are more plentiful every 11 years. Flares and other powerful solar events that
sometimes wreak havoc with Earth's communications systems also are associated
with heightened sunspot activity. In addition to looking at the Sun, the
satellite investigated celestial sources of X-rays in the Milky Way and beyond.
It carried eight experiments.
