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 ...
NASA also cooperates with other U.S. civil agencies such as the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS) to deliver space assets supporting the weather and civil remote sensing mandates of those organizations. In 2022, NASA's annual budget was approximately $24 billion.
NASA: Orbiter Cancelled Canceled due to a shift in NASA's priorities, which favored crewed space missions instead. [55] The probe would have confirmed the potential existence of a subsurface ocean beneath Europa's surface, with Ganymede and Callisto also being targeted for exploration. 14 Jupiter Magnetospheric Orbiter: Jupiter Magnetospheric ...

The Suomi National Polar-orbiting Partnership , previously known as the National Polar-orbiting Operational Environmental Satellite System Preparatory Project and NPP-Bridge, has a nearly identical design as NOAA-20 and shares some ground systems with it but it was not designed as a part of JPSS. It was originally proposed as a proof-of-concept ...
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.
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.
The Exploration Systems Architecture Study (ESAS) is the official title of a large-scale, system level study released by the National Aeronautics and Space Administration (NASA) in November 2005 of his goal of returning astronauts to the Moon and eventually Mars—known as the Vision for Space Exploration (and unofficially as "Moon, Mars and Beyond" in some aerospace circles, though the ...
