Nancy Roman oversaw the development of the Orbiting Solar Observatory program from 1961 to 1963. [2] The basic design of the entire series featured a rotating section, the "Wheel", to provide gyroscopic stability. A second section, the "Sail", was driven electrically against the Wheel's rotation, and stabilized to point at the Sun.
OSO 3 (Orbiting Solar Observatory 3), or Third Orbiting Solar Observatory [2] [3] (known as OSO E2 before launch) was launched on March 8, 1967, into a nearly circular orbit of mean altitude 550 km, inclined at 33° to the equatorial plane. Its on-board tape recorder failed on June 28, 1968, allowing only the acquisition of sparse real-time ...
Ball Aerospace began building pointing controls for military rockets in 1956. The aerospace part of the Ball Corporation was then known as Ball Brothers Research Corporation, and later won a contract to build some of NASA's first spacecraft, the Orbiting Solar Observatory satellites. The company has been responsible for numerous technological ...
The Orbiting Astronomical Observatory (OAO) satellites were a series of four American space observatories launched by NASA between 1966 and 1972, [1] managed by NASA Chief of Astronomy Nancy Grace Roman. These observatories, including the first successful space telescope, provided the first high-quality observations of many objects in ...
Four Great Observatories. NASA's series of Great Observatories satellites are four large, powerful space-based astronomical telescopes launched between 1990 and 2003. They were built with different technology to examine specific wavelength/energy regions of the electromagnetic spectrum: gamma rays, X-rays, visible and ultraviolet light, and infrared light.
The first ultraviolet spectrum of the Sun was obtained in 1946, [21] and NASA launched the Orbiting Solar Observatory (OSO) to obtain UV, X-ray, and gamma-ray spectra in 1962. [22] An orbiting solar telescope was launched in 1962 by the United Kingdom as part of the Ariel programme , and in 1966 NASA launched the first Orbiting Astronomical ...
A small asteroid will be pulled into orbit around the Earth as a “mini-moon” later this month before the space rock departs into other parts of the solar system.. The 10m-wide asteroid, dubbed ...
The horizontal Snow solar observatory was built on Mount Wilson in 1904. It was soon found that heat radiation was disrupting observations. Almost as soon as the Snow Observatory opened, plans were started for a 60-foot-tall (18 m) tower that opened in 1908 followed by a 150-foot (46 m) tower in 1912.
