Subsidence, rockfalls and landslides threaten potentially devastating human and economic consequences across Europe – but satellites can help.
For the second straight day, SpaceX had to cancel the scheduled launch of a Falcon 9 rocket on Saturday evening, further pushing back the planned deployment of six Orbcomm communications satellites.

On Tuesday Google confirmed that it would acquire Skybox Imaging, a satellite imaging and analytics startup, for $500 million.
Now that the Venus Express spacecraft has completed its eight-year scientific mission and is preparing to plunge into the planet’s atmosphere, the ESA has started providing regular space weather reports for an extraterrestrial world for the first time.
Google announced that it will spend more than $1 billion on a fleet of satellites to extend Internet access to unwired regions of the globe.
The new Global Precipitation Measurement Core Observatory satellite is now in the hands of the engineers who will fly the spacecraft and ensure the steady flow of data on rain and snow for the life of the mission.
Down on the ground, death equals stillness – but not in space. Derelict satellites can tumble in unpredictable ways and ESA’s team tasked with developing a space salvage mission want to find out why.
Although not yet operational, the new Sentinel-1A satellite has provided radar data for mapping the floods in Bosnia and Herzegovina.
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...
