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...

Connecting Next Generation Of Spacecraft With One Ring
2014-06-04 03:34:43

ESA Connecting spacecraft in orbit will never be simple, but ESA is taking the next step to allow the next generation of vehicles of all types from around the world to link up with each other. The International Space Station has two sets of incompatible docking ports, one designed for Russian spacecraft and Europe’s space freighter, and another design for the now-retired US Space Shuttle. There also are berthing ports for vessels that cannot dock on their own but are first captured...

How Do You Catch A Satellite?
2014-02-21 10:50:46

ESA Standard space dockings are difficult enough, but a future ESA mission plans to capture derelict satellites adrift in orbit. Part of an effort to control space debris, the shopping list of new technologies this ambitious mission requires is set for discussion with industry experts. ESA’s Clean Space initiative is studying the e.DeOrbit mission for removing debris, aiming to reduce the environmental impact of the space industry on Earth and space alike. Earth's debris halo...

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Lawrence Livermore National Laboratory (LLNL) in California have developed and tested a series of ground-based mini-satellites that will be used to help control traffic in space. These so-called “space cops” were used by the LLNL team to capture a series of six images over a 60-hour period to prove that they can be used to alter the orbit of other probes traveling in low-earth orbit. The plan is to use the...

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...

Luxury Lifestyle Brand Showcases The Results Of A More Provoked Life NEW YORK, Dec. 30, 2013 /PRNewswire/ -- Equinox, the leaders in fitness and lifestyle, unveiled today its 2014 ad campaign: Equinox Made Me Do It. The campaign, created by Wieden+Kennedy New York, highlights the results of living a more provoked life. The ads connect the cause and effect of an Equinox workout, asserting that a good workout can be a bad influence. "We looked to our members as the core inspiration...

Space Weather Damaging Satellites
2013-09-16 14:32:14

Lee Rannals for redOrbit.com - Your Universe Online Scientists say space weather could be causing some satellite malfunctions due to high-energy electrons. Space weather is a biproduct of solar activity. When an eruption takes place on the sun's surface, it ejects charged particles which sometimes head straight towards Earth. MIT researchers writing in the journal Space Weather say this phenomenon is causing some geostationary satellites to experience failures despite efforts to protect...

New Explorer Mission Chooses The 'Goldilocks Orbit'
2013-08-01 08:05:06

NASA Principal Investigator George Ricker likes to call it the "Goldilocks orbit" -- it's not too close to Earth and her Moon, and it's not too far. In fact, it's just right. And as a result of this never-before-used orbit -- advanced and fine-tuned by NASA engineers and other members of the Transiting Exoplanet Survey Satellite (TESS) team -- the Explorer mission led by Ricker will be perfectly positioned to map the locations of more than 500 transiting exoplanets, extrasolar planets...

Moon Will Be Super On June 24th
2013-06-22 04:45:01

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The Moon appears to be in a nearly circular orbit around the Earth. But that word "nearly" means that there are slight variations in its motion across the heavens. As it turns out, the distance from the Earth to the Moon varies by about 30,000 miles. This sounds like a lot, but it only represents about a 6-7 percent deviation from the average distance between the two bodies. On Earth, the difference between when the Moon...

Autumnal Equinox -- In astronomy, is the equinox at the beginning of autumn in the northern hemisphere: the moment when the sun appears to cross the celestial equator, heading southward. The equinox occurs around September 22-24, varying slightly each year according to the 400 year cycle of leap years in the Gregorian Calendar. In the southern hemisphere, the equinox occurs at the same moment, but at the beginning of spring. There are two conventions for dealing with this: either 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...

Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...
