NASA Orbiter To Begin Collecting Atmospheric Data After Lunar Arrival
2013-11-22 10:05:42

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) successfully entered orbit around the moon’s equator earlier this week and is now set to begin collecting atmospheric data, the US space agency has announced. The spacecraft, which enjoyed a successful launch from the Wallops Flight Facility in Virginia over two months ago, entered its planned orbit around the moon’s equator on Wednesday. It now orbits the moon...

India's Flagship Martian Orbiter Has A Minor Hiccup Over Earth
2013-11-11 13:26:06

Lawrence LeBlond for redOrbit.com - Your Universe Online India’s landmark mission to mars, which was launched just under a week ago, has hit a minor speed bump while in orbit over Earth. The country’s Mars Orbiter Mission, otherwise known as Mangalyaan or MOM, encountered a problem with a liquid fuel thruster, causing the probe to miss an intended higher orbital trajectory. India maintains that this minor issue is just that and will not set the country back in its attempt to be only...

No Damages Reported As GOCE Satellite Falls Back To Earth
2013-11-11 07:39:22

[ Watch the Video: GOCE Safely Burns Up In The Atmosphere ] redOrbit Staff & Wire Reports - Your Universe Online A defunct satellite that had been mapping the Earth’s gravitational field fell back to Earth at approximately 7pm ET Sunday (01:00 CET Monday), the European Space Agency (ESA) has confirmed. The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) probe re-entered the planet’s atmosphere during a descending orbital pass extending across Siberia, the...

Swarm Constellation Preps For Launch, Three Satellites In One Payload
2013-11-09 05:19:07

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) said that it has finished placing all three Swarm satellites on their launch adapter, getting them ready for launch in two weeks. The latest update of the Swarm constellation means that the new Earth observation mission is on track for its November 22 launch. The Swarm constellation will be measuring the strength and direction of the magnetic electric fields around Earth. ESA said that the satellites...

ESA's Defunct GOCE Satellite Expected To Fall Back To Earth Soon
2013-11-07 10:14:38

redOrbit Staff & Wire Reports - Your Universe Online Beware of falling satellites this weekend, as a European Space Agency (ESA) probe that had been mapping the planet’s gravitational field is expected to plummet back to Earth within the next few days. The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite was launched in 2009, and managed to remain in low-orbit some 160 miles above the Earth thanks to its ion engine, UPI reported on Wednesday. However,...

ESA's Next Pair Of Galileo Satellites Undergo Crucial Testing
2013-11-07 07:46:58

April Flowers for redOrbit.com - Your Universe Online At a technical center in the Netherlands, the European Space Agency's (ESA) next pair of Galileo satellites have been the focus of a busy fall season. The satellites are undergoing a continuing, full-scale campaign to ensure their readiness for space. The first of the pair of satellites is halfway through a five-week immersion in vacuum and temperature extremes. This "thermal-vacuum" testing mimics the conditions the satellites will...

LADEE Laser Advancing Space Communications
2013-11-04 18:16:41

Lee Rannals for redOrbit.com – Your Universe Online NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) orbiter is working with the European Space Agency’s (ESA) ground station on the island of Tenerife to deliver data like never before about the Moon. LADEE was launched on September 7 and began orbiting the Moon in October with a mission to analyze the Moon’s environment. The spacecraft is carrying a new laser terminal capable of delivering data at speeds that are far...

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...
