Space Debris Threat From Envisat Explored By University Of Leicester Students
2014-02-20 07:32:18

redOrbit Staff & Wire Reports - Your Universe Online A recently-published paper from physics students at the University of Leicester explores the possibility that a massive observational satellite that lost contact with Earth in 2012 could be the catalyst that sets off a chain of events much like those depicted in the Academy Award-nominated film Gravity. Writing in the Journal of Physics Special Topics, a peer-reviewed student journal run by the University’s Department of Physics...

Proba-V Working Around The Clock
2014-02-18 08:49:27

ESA More than 5000 images, 65 daily global maps and six 10-day global syntheses, plus a quick peek at the Olympics: in its first two months of work, the vegetation-monitoring Proba-V minisatellite has yielded a valuable harvest for around a hundred scientific teams around the globe. Measuring less than a cubic metre, Proba-V tracks vegetation growth across the world on a near-daily basis – 93% of the globe is covered in one day, 100% in two days – using its main wide-viewing...

Outernet says on its site that there are more...

Soviet-era Spy Satellite Burns Up Harmlessly In Earth's Atmosphere
2014-02-17 05:57:42

Lawrence LeBlond for redOrbit.com - Your Universe Online Fragments of a Soviet-era spy satellite, which was expected to crash back to Earth, had instead burned up on reentry into the atmosphere on Sunday. Colonel Dmitry Zenin, a spokesman for the Russian Defense Ministry, told Itar-Tass news agency that Kosmos-1220, a military signal intelligence satellite, reentered Earth’s atmosphere and burned up at about 5:58 p.m. local time (8:58 a.m. EST). The satellite, which had been in...

NASA Currently Testing New Technologies For Robotic Refueling

Dewayne Washington/Adrienne Alessandro - NASA [ Watch The Video: Another Step Toward Servicing Satellites in Space ] It's corrosive, it's hazardous, and it can cause an explosion powerful enough to thrust a satellite forward in space. Multiple NASA centers are currently conducting a remotely controlled test of new technologies that would empower future space robots to transfer this dangerous fluid -- satellite oxidizer -- into the propellant tanks of spacecraft in space today....

DARPA Dreams Up Satellite-Launching Hypersonic Space Plane
2014-02-12 15:03:51

Lee Rannals for redOrbit.com - Your Universe Online A new program established by DARPA is looking to build a spaceplane that is able to launch satellites into orbit. The Experimental Spaceplane (XS-1) program will help add a quick, affordable and routine ride to space. The program aims to build a fully reusable unmanned hypersonic vehicle that DARPA said would be like providing “aircraft-like access to space.” The proposed vehicle would launch from a “clean pad” with a small...

Galileo Working Well
2014-02-12 12:08:28

[ Watch The Video: Galileo Validated in Orbit VNR ] ESA The in-orbit validation of Galileo has been achieved: Europe now has the operational nucleus of its own satellite navigation constellation in place – the world’s first civil-owned and operated satnav system. In 2011 and 2012 the first four satellites were launched into orbit. Four is the minimum number needed to perform navigation fixes. In the following year, these satellites were combined with a growing global ground...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
