The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...

The NASA program name is based on President John F. Kennedy's "New Frontier" political agenda speech in 1960, in which he constantly used the words "New ...
The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies. These are not necessarily in the public domain. Materials based on Hubble Space Telescope data may be copyrighted if they are not explicitly produced by the STScI . [1]
In all, 38 Discoverer satellites were launched by February 1962, although the satellite reconnaissance program continued until 1972 as the CORONA project. The program documents were declassified in 1995. [3] Discoverer 1 was a test of the performance capabilities of the propulsion and guidance system of the booster and satellite.
The Ride Report is the informal name of the report titled NASA Leadership and America's Future in Space: A Report to the Administrator. [1] In 1986, a task force under the leadership of Sally Ride was asked to formulate a new strategy for NASA. The report was issued in 1987. The Ride Report proposed four main initiatives for study and evaluation.
