Lee Rannals for redOrbit.com – Your Universe Online Japan launched two satellites into orbit on Sunday, capable of spying and offering sharp images for its government defense and intelligence agencies. Officials say the launch of the satellites, which included an operational radar satellite and experimental optical probe, went smoothly. The two intelligence satellites now in orbit could potentially help to keep an eye on North Korea as it tests rockets, and sets itself on a course...

[ Watch the Video: Phoenix Program Demonstration of Latest Advances ] Lee Rannals for redOrbit.com – Your Universe Online One new satellite repurposing program could bring old satellites out of retirement, giving them a new goal as they remain in orbit. DARPA said on Tuesday it is developing a new program for the old satellites that hurdle through space 22,000 miles above the Earth. The goal of the Phoenix program is to fundamentally change how space systems could be designed...
NASA NASA's Tracking and Data Relay Satellite System will get an upgrade this month when the agency launches the first of a new generation of communications satellites to connect spacecraft to the ground stations that support them. A United Launch Alliance Atlas V 401 is due to loft the TDRS-K spacecraft Jan. 29 on a course to geosynchronous orbit where the spacecraft will have a wide view of Earth. From that position, the spacecraft will pick up signals from NASA's fleet of...
[Watch Video: RRM Day One - Captured] Lee Rannals for redOrbit.com – Your Universe Online NASA is about to take a new step in advancing robotic satellite-servicing technologies by testing the Robotic Refueling Mission (RRM). The space agency's investigation could impact the satellites that deliver products Americans rely on daily, such as weather reports, cell phones and television news. Controllers will be using the International Space Station's (ISS) remotely operated Special...
PARIS, January 15, 2013 /PRNewswire/ -- Eutelsat Communications (Euronext Paris: ETL) today announced the deployment on a future satellite of a new generation of advanced functions designed by European industry to further raise the bar of performance, flexibility and signal security. The enhancements will fly for the first time on the EUTELSAT 8 West B satellite which is due to be launched in 2015. The new functions developed by the satellite's prime contractor, Thales...
NASA In mid-January, NASA will take the next step in advancing robotic satellite-servicing technologies as it tests the Robotic Refueling Mission, or RRM aboard the International Space Station. The investigation may one day substantially impact the many satellites that deliver products Americans rely upon daily, such as weather reports, cell phones and television news. During five days of operations, controllers from NASA and the Canadian Space Agency will use the space station's...
redOrbit Staff & Wire Reports - Your Universe Online The Landsat Data Continuity Mission (LDCM), the eighth probe in NASA's long-running satellite imagery acquisition program, has been delivered to California's Vandenberg Air Force Base in preparation for its upcoming launch, officials with the US space agency announced on Thursday. The LDCM, which was built and tested by Arizona-based Orbital Sciences Corporation and departed their facility onboard a semi-trailer truck earlier this...
PALO ALTO, California and BERN, Switzerland, Dec. 19, 2012 /PRNewswire/ - Space Systems/Loral (SSL) and Sea Launch AG (Sea Launch) today announced that the Independent Oversight Board (IOB) formed to investigate the solar array deployment anomaly on a satellite launched in the spring of 2012 has successfully reached a unanimous conclusion. The IOB, which was comprised of three highly regarded industry experts, worked with a comprehensive team of engineers from both SSL and Sea...
Latest Satellite Reference Libraries
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...
