The new Global Precipitation Measurement Core Observatory satellite is now in the hands of the engineers who will fly the spacecraft and ensure the steady flow of data on rain and snow for the life of the mission.
Down on the ground, death equals stillness – but not in space. Derelict satellites can tumble in unpredictable ways and ESA’s team tasked with developing a space salvage mission want to find out why.
Although not yet operational, the new Sentinel-1A satellite has provided radar data for mapping the floods in Bosnia and Herzegovina.
GlobaFone's Education Series webinar will educate satellite phone buyers and end users on their options and how to sift through them to make a good decision Portsmouth,
The Air Force is now working as fast as it can to certify SpaceX as a venerable launch provider for the nation’s military and intelligence satellites, according to General William Shelton, who heads the Air Force Space Command.
REDONDO BEACH, Calif., May 21, 2014 /PRNewswire/ -- Two scientific spacecraft and a military communications payload produced by Northrop Grumman Corporation (NYSE: NOC) are observing major on orbit
The first documents signalling the go-ahead for Europe’s fleet of MetOp Second Generation weather satellites were signed today in the presence of the German Chancellor Angela Merkel at the Berlin Air Show.
A Russian telecommunications satellite crashed to the ground on Friday as a result of a launch failure by the country’s Proton-M rocket.
Ongoing tensions between the US and Russia have left the US Air Force (USAF) scrambling for alternatives to Russian-built rocket engines, but could pay off big for some American companies in the long run.

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...
NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...
Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...
Orbit -- An orbit is the path that an object makes around another object under the influence of some force. The classical example is that of the solar system, where the Earth, other planets, asteroids, comets, and smaller pieces of rubble are in orbit around the Sun; and moons are in orbit around planets. These days, many artificial satellites are in orbit around the Earth. Understanding orbits There are a few common ways of understanding orbits. -- As the object moves, it...
