April Flowers for redOrbit.com - Your Universe Online Humans have thrown a lot of junk into space since the Space Race began in the late 1950s. NASA has an entire website devoted to the types and sizes of space trash orbiting the planet — from defunct spacecraft and launch vehicle stages all the way down to specks of paint released by thermal stress or small particle impacts. NASA estimates that over 21,000 bits of orbital debris larger than 10 centimeters exists currently. The numbers...

Chuck Bednar for redOrbit.com – Your Universe Online Five geckos sent into space so that researchers could analyze their reproductive habits in microgravity have died in orbit, officials from the Russian Federal Space Agency (Roscosmos) confirmed on Monday. The four male and one female lizards were sent into space on a Photon-M4 satellite on July 19 and returned to Earth 44 days later, explained Howard Amos of The Telegraph. However, when Roscosmos scientists traveled to the probe’s...

Miniature Satellites Take Wireless Sensor Networks Into Space
2014-08-26 03:06:34

World Scientific A team of engineers from Singapore has successfully piloted the world's first ZigBee wireless sensor network (WSN) for satellite communications. With the weight of payloads being a major constraint in satellite design, constructing a lightweight, low power-consuming, wireless communication system to do away with cabling inside the satellite has always been a challenge for system designers. The engineering team at the Satellite Research Centre of Nanyang Technological...

Galileo satellites meet
2014-08-18 14:54:29

European Space Agency Final functional testing of Europe’s twin Galileo navigation satellites has been completed at Europe’s Spaceport in French Guiana, on track for launch this Thursday. The fueling of the two satellites, allowing them to fine-tune their orbits and maintain their altitude over the course of their 12-year lifetimes, took place on 7–8 August. Engineers donned protective SCAPE (Self Contained Atmospheric Protective Ensemble) suits to fill the satellites with...

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...
