A group of researchers from MIT has developed a new algorithm for gauging the rotation of objects in space using only visual information.
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.
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.
Researchers from the Lawrence Livermore National Laboratory in California have developed and tested a series of ground-based mini-satellites that will be used to help control traffic in space.
The ESA's Gaia spacecraft made a final, modest adjustment yesterday afternoon to keep it on track for its orbit around nothing.

Scientists say space weather could be causing some satellite malfunctions due to high-energy electrons.
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.
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.
EQUINOX Owner-Operator Solutions today announced the launch of EQUINOX Mailbox, the industry’s first online solution for truck drivers to review and respond to mail received at home while drivers
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...
