Satellite Time-Lapse Animation Shows US East Coast Snowy Winter
2014-03-28 12:05:26

[ Watch The Video: GOES Satellite Movie of 2014 Winter Storms ] Rob Gutro, NASA A new time-lapse animation of data from NOAA's GOES-East satellite provides a good picture of why the US East Coast experienced a snowier than normal winter. The new animation shows the movement of storms from January 1 to March 24. NOAA's Geostationary Operational Environmental Satellites or GOES-East imagery from January 1 to March 24 was compiled into three videos made by NASA/NOAA's GOES Project...

Reducing Satellite Battery Debris Threat
2014-03-13 14:19:05

ESA Across a satellite’s working life, batteries keep the craft’s heart beating whenever it leaves sunlight. But after its mission ends, those same batteries may threaten catastrophe. Space debris mitigation rules require the complete deactivation of electrical power sources aboard a satellite on retirement, in order to guard against explosive accidents that might produce fresh debris dangerous to other satellites. Now a new study by ESA’s Clean Space initiative – tasked with...

Acquiring Signals From A Speeding Satellite
2014-03-07 14:51:31

ESA Soaring high above Earth as they speed through space, satellites are difficult targets to track. Now a new approach developed in Europe is helping ground stations to acquire signals faster and more accurately than ever before. During launch, a satellite is flung into orbit with tremendous force, attaining speeds of over 28 000 km/h – about 40 times faster than a commercial airliner. A critical moment is when the satellite separates from its rocket and starts transmitting radio...

NASA Looks To Robots To Refuel And Repair Satellites In Orbit
2014-03-07 13:12:24

Lee Rannals for redOrbit.com - Your Universe Online NASA is using the International Space Station (ISS) as a test bed for technologies that could refuel and repair existing satellites in orbit. The space agency said it is preparing another round of demonstrations on the space station to test the new technology. This testing will focus on real-time relative navigation, spacecraft inspection and the replenishment of cryogens in satellites that were not initially built for in-flight...

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...
