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 ...
Charles Hutchins Hapgood (May 17, 1904 – December 21, 1982) [1] was an American college professor and author who became one of the best known advocates of the pseudo-scientific claim of a rapid and recent pole shift with catastrophic results.
NPOESS was a tri-agency program led by an Integrated Program Office (IPO) containing staff from the US Department of Defense, National Oceanic and Atmospheric Administration, and NASA. [1] NPOESS was to be operated by the NOAA/ National Environmental Satellite, Data, and Information Service (NESDIS) / NPOESS Program Executive Office Flight ...
The United States has developed many space programs since the beginning of the spaceflight era in the mid-20th century. The government runs space programs by three primary agencies: NASA for civil space; the United States Space Force for military space; and the National Reconnaissance Office for intelligence space. These entities have invested ...
NASA computer simulation using the model of Glatzmaier and Roberts. [38] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and vertical. The dense clusters of lines are within the Earth's core. [27]
The Surveyor Program was a NASA program that, from 1966 through 1968, sent seven robotic spacecraft to the surface of the Moon. Its primary goal was to demonstrate the feasibility of soft landings on the Moon. The program was implemented by NASA's Jet Propulsion Laboratory (JPL) to prepare for the Apollo program. [22]
Hugh Auchincloss Brown (23 December 1879 – 19 November 1975) was an electrical engineer who advanced a theory of catastrophic pole shift.Brown claimed that massive accumulation of ice at the poles caused recurring tipping of the axis in cycles of approximately 4000–7500 years.
The President stated "The directive I am signing today will refocus America's space program on human exploration and discovery." "It marks a first step in returning American astronauts to the Moon for the first time since 1972, for long-term exploration and use.
