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...

New Robotic Refueling Technologies Tested By NASA

"This is the first time that anyone has tested this type of technology, and we've proven that it works....

Eastern US Winter Storm Track Captured On Satellite Video
2014-03-04 14:57:37

[ Watch The Video: Satellite Video Captures the Eastern U.S. Winter Storm Track ] Rob Gutro, NASA As NOAA's GOES-East satellite sat in a fixed orbit in space it monitored and provided visible and infrared imagery of the major winter storm that hit the US east coast on March 2 and 3. Now, that data has been compiled and made into a video at NASA. On March 2 and 3, a major winter storm brought snow to the mid-Atlantic, freezing rain to the Carolinas and rain and some freezing...

NASA Weather And Climate Tracking Satellite Has Successul Launch

[ Watch the Video: ScienceCasts - Follow the Water ] Lee Rannals for redOrbit.com - Your Universe Online NASA launched its Global Precipitation Measurement (GPM) Core Observatory from Tanegashima Space Center in Japan on Thursday (Feb 27). The new spacecraft will be another eye-in-the-sky for NASA and JAXA (Japan Aerospace Exploration Agency) to help take measurements on rain and snowfall. GPM will eventually help scientists keep track of future extreme weather events and manage...

European Space Agency The Sentinel-1A radar satellite has arrived at Europe’s Spaceport in French Guiana to be prepared over the coming weeks for launch on 3 April. Its launch will mark a new shift in Earth observation, focusing on operational missions to support users for decades to come. This first mission carries an advanced radar sensor to image Earth’s surface through cloud and rain and regardless of whether it is day or night. Delivered by an Antonov aircraft, it was...

Air Force's 'Neighborhood Watch' Program Will Spy On Other Countries
2014-02-24 13:38:00

Lee Rannals for redOrbit.com - Your Universe Online General William Shelton said at the Air Force Association meeting in Orlando on Friday that the US will be launching satellites to spy on other countries. The head of Air Force Space Command said at the event that the “neighborhood watch program” will provide spying capabilities, as well as added eyes in the sky to keep track of space debris while orbiting 22,300 miles above the Earth. Shelton said the satellites will be used to...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
