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 NOAA/NASA portion is called the Joint Polar Satellite System (JPSS). The first satellite in the program – originally called JPSS-1, but now known as NOAA-20 – was constructed by Ball Aerospace & Technologies Corp., under a fixed price contract of $248 million with a performance period through Feb. 1, 2015.

A coastal community in Southern California is shifting downslope -- and closer to the Pacific Ocean -- at a rapid rate, according to NASA. The Palos Verdes Peninsula is well-known for its ...
Vandenberg Space Launch Complex 6 (SLC-6, pronounced "Slick Six") is a launch pad and associated support infrastructure at Vandenberg Space Force Base in California. Construction at the site began in 1966, but the first launch didn't occur until 1995 due to program cancellations and subsequent repurposing efforts.
The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites. JPSS will provide the global environmental data used in numerical weather prediction models for forecasts, and scientific data used for climate monitoring.
California and NASA, with the backing of billionaire Michael Bloomberg, on Thursday unveiled a $100 million effort to pinpoint large emissions of greenhouse gases from individual sources like ...
In the early 20th century, geologists such as Bernard Brunhes first noticed that some volcanic rocks were magnetized opposite to the direction of the local Earth's field. . The first systematic evidence for and time-scale estimate of the magnetic reversals were made by Motonori Matuyama in the late 1920s; he observed that rocks with reversed fields were all of early Pleistocene age or old
The California Space Authority (CSA) was a nonprofit corporation representing the commercial, civil, and national defense/homeland security interests of California's diverse space enterprise community in four domains: Industry, Government, Academia, and Workforce.
