Satellite Imagery A Promising Tool To Monitor Arctic Polar Bears
2014-07-10 03:14:50

PLOS Polar bear population estimates based on satellite images are similar to aerial estimates, according to a study published July 9, 2014 in the open-access journal PLOS ONE by Seth Stapleton from United States Geological Survey and colleagues. The potentially severe impacts of climate change in the Arctic may threaten regional wildlife. Scientists trying to develop efficient and effective wildlife monitoring techniques to track Arctic populations face great challenges, including the...

Harpoons May Be Used By ESA To Clear Earth's Orbit Of Space Junk
2014-06-24 10:53:21

Gerard LeBlond for redorbit.com - Your Universe Online The European Space Agency (ESA) is embarking on an age old practice of using harpoons for the future goal of clearing orbits of tumbling satellites and other hazardous space junk. The Earth’s orbit is filled with decades of launched satellites that are no longer being used, along with other space debris that pose a collision threat with ongoing missions. There are more than 17,000 trackable objects floating in Earth’s orbit....

Satellites Used To Watch For Shifting Land
2014-06-23 03:51:37

ESA Subsidence, rockfalls and landslides threaten potentially devastating human and economic consequences across Europe – but satellites can help. Traditional monitoring such as photographic mapping to measure changes in the landscape works well for specific locations but is labor intensive and costly. Now, ESA has looked at using satellites to watch for hazards across broad areas that could affect road and rail networks. The outcome is so promising that the resulting monitoring...

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...
