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...

[ Watch The Video: Six Decades Of A Warming Earth ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Goddard Institute for Space Studies (GISS) in New York found that 2013 tied 2009 and 2006 for the seventh warmest year since 1880. GISS analyzes global surface temperatures and released an updated report on Tuesday on the 2013 temperatures from around the world. According to the report, the average temperature last year was 58.3 degree Fahrenheit, which is about 1.1 degrees...

Space Droids Battle To Save Our Planet

[ 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...

(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...

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...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
