2014-06-02 03:00:25

Ellen Gray, NASA 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. The official handover to the Earth Science Mission Operations team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, on May 29, marked the end of a successful check-out period. The Global Precipitation Measurement (GPM) mission is a joint...

Examining Satellites’ Mysterious Death Tumbling
2014-05-30 03:50:01

ESA 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. In recent years, satellites beginning uncontrolled reentries have been tracked, such as Russia’s Phobos-Grunt and Germany’s Rosat. In a few cases, satellites suffering unexpected failures in orbit have also been followed, including ESA’s Envisat and Japan’s ADEOS-II. In...

Sentinel-1A Satellite Data Aids Balkan Flood Relief
2014-05-28 03:40:40

ESA Although not yet operational, the new Sentinel-1A satellite has provided radar data for mapping the floods in Bosnia and Herzegovina. Heavy rainfall leading to widespread flooding and landslides has hit large parts of the Balkans, killing dozens of people and leaving hundreds of thousands displaced. Jan Kucera of the Europan Commission’s Joint Research Centre is supervising the technical aspect of the Copernicus Emergency Management Service (EMS). While mapping the flooding in...

SpaceX Goes From Suing Air Force To Potentially Launching Its Satellites
2014-05-22 10:53:54

Lawrence LeBlond for redOrbit.com - Your Universe Online Late last month Elon Musk announced he was displeased that the US Air Force shut his company, Space Exploration Technologies (SpaceX), out of the competition market for government launches. He was so annoyed by it that he filed a legal complaint against United Launch Alliance’s (ULA) monopoly over military launches. Less than a week after that filing, a federal court judge filed a temporary injunction against ULA’s...

ESA The first documents signaling 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. Set to debut in 2021, this next generation will comprise three pairs of satellites to secure essential information for weather forecasting through the decades beyond. Not only will MetOp Second Generation (MetOp-SG) offer continuity of the current MetOp series, today the main...

High Tech Telecom Satellite Destroyed After Russian Rocket Launch Fails
2014-05-16 13:17:27

Brett Smith for redOrbit.com - Your Universe Online A Russian telecommunications satellite crashed to the ground on Friday as a result of a launch failure by the country’s Proton-M rocket. Launched in the early morning hours from the Baikonur Cosmodrome in Kazakhstan, the rocket experienced an "emergency situation" that kept it from going into orbit, Russian space agency Roscosmos said. Russian media reported that an issue with the rocket occurred about 94 miles above the Earth and...

Tensions Between US And Russia Leave Air Force Scrambling For Launch Alternatives
2014-05-16 04:44:01

redOrbit Staff & Wire Reports - Your Universe Online 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, according to various media reports published earlier this week. The recent announcement by Russian officials that they would no longer allow the US access to its rocket engines, and would keep the USAF from using them to launch...

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...
