Space Droids Battle To Save Our Planet
2014-01-21 11:52:05

[ Watch The Video: Zero Robotics Competition 2013 ] ESA A comet heading towards Earth threatens humanity’s existence – that was the virtual scenario of this year’s Zero Robotics tournament. Secondary-school students from across Europe controlled miniature satellites on the International Space Station in a competition to save our planet. The Space Station was turned into a playing field for the finals. The ultimate robot game challenged youngsters to write algorithms that...

SGDC system will better address Brazil government’s satellite communications needs. Exton, PA (PRWEB) January 15, 2014 Analytical Graphics, Inc. (AGI), the producer of commercial modeling and analysis software for the space, defense and intelligence communities, together with its partner in Brazil, Anacom, today announced that Visiona Technology Espacial SA is using its Systems Tool Kit (STK) software in support of Brazil’s Defense and Strategic Communications Geostationary Satellite...

Gaia Orbits Nothing
2014-01-15 13:51:10

[ Watch the Video: Gaia Reaches Virtual Point Of Nothingness ] Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) Gaia spacecraft made a final, modest adjustment yesterday afternoon to keep it on track for its orbit around nothing. Gaia, which is being branded as ESA’s billion-star surveyor, finalized it’s entry into orbit around a virtual point far out in space known as L2. ESA said that Gaia made a short thruster burn on Tuesday to help...

Gaia Ready For Operational Orbit
2014-01-08 12:24:20

Brett Smith for redOrbit.com - Your Universe Online The European Space Agency (ESA) has announced that its billion-dollar orbiting observatory Gaia is in its operational orbit and ready to begin surveying the stars. Launched from the ESA’s facility in Kourou, French Guiana on December 19, Gaia is now in a gravitationally stable point called ‘L2,’ orbiting nearly 1 million miles from Earth. “Entering orbit around L2 is a rather complex endeavor, achieved by firing Gaia’s...

Satellites Could Be Deorbited Using New Gossamer Sail
2013-12-22 03:34:52

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Surrey have developed a new method to bring aging satellites back to Earth so they no longer pose a threat to spacecraft or other probes by continuing to orbit in a nonworking state. The device is an ultra-lightweight “gossamer sail” that could be packed into satellites which could be deployed near the end of their life cycles, the European Space Agency (ESA) – which has funded the project...

Sounds Of Space
2013-12-20 16:31:24

Lee Rannals for redOrbit.com - Your Universe Online A scientist from the University of Leicester is helping to reveal the sounds of space by using satellite data. Some areas of space are so quiet you can hear your heart beat, but there are other areas that have the capacity to be as noisy as places on Earth. A multimedia composer at the University’s Space Center decided to generate a few of the surprising Earth-like sounds one could find in space. Andrew Williams used data collected from...

China Suffers Huge Setback With Satellite Launch Failure
2013-12-09 14:11:33

Lee Rannals for redOrbit.com - Your Universe Online China’s space program was dealt another setback on Monday when it lost a $250 million Earth observation satellite just days after successfully launching its first lunar rover. The satellite, developed by China and Brazil, was lost when a Long March 4B rocket failed to put the spacecraft into its proper orbit. "The rocket malfunctioned during the flight, and the satellite failed to enter orbit," sources told the state-owned Xinhua...

Artificial Heart Using Space Tech Approved For Human Trials In France
2013-12-05 14:45:57

Lee Rannals for redOrbit.com - Your Universe Online France has approved an artificial heart containing miniaturized space technology for human trials. French company Carmat produced their first completely artificial heart earlier this year with the help of aerospace giant Astrium. Carmat applied Astrium’s expertise in building spacecraft to guarantee the necessary precision and durability for an artificial human organ like a heart. The artificial heart is fashioned partly from...

Search Discovery (SDI) announced today the release of Airlock, a new tool that will allow companies to seamlessly transition from the legacy version of Google Analytics to the new Google Universal Analytics without the need to re-tag a site. Search Discovery is offering Airlock free of charge. Atlanta, Georgia (PRWEB) December 04, 2013 Search Discovery (SDI) announced today the release of Airlock, a new tool that will allow companies to seamlessly transition from the legacy version of...

Laser Communication Mission Launch Scheduled For 2017
2013-12-04 11:51:19

[ Watch The Video: LCRD: From Vision to Reality ] NASA NASA’s next laser communication mission recently passed a Preliminary Design Review (PDR), another major milestone towards the launch of the Laser Communications Relay Demonstration (LCRD) scheduled for 2017. The PDR is a major agency evaluation milestone of the engineering plan to execute the build and launch of LCRD onboard a Space Systems Loral commercial satellite. “The board concluded that the LCRD review was a...

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...
