Latest Satellite Stories
From hundreds of miles in orbit, NASA satellites can measure how much rain falls in Niger or detect plant health in Mali. But on the ground, many African farmers and food distributors don't have good information about the growing conditions a few dozen miles down the road.
The third launch by Europe’s new small launcher, Vega, has delivered Kazakhstan’s first satellite for high-resolution Earth observation into its planned orbit.

SpaceX has proven to NASA that it is a viable contender in the launch of scientific missions to the International Space Station and now it wants to prove it can also send payloads into space for the US government,
OTTAWA and GATINEAU, QC, April 24, 2014 /CNW/ - The Canadian Radio-television and Telecommunications Commission (CRTC) today launched the third phase of Let's Talk TV: A Conversation with Canadians.
A fleet of orbiting satellites monitors Earth constantly. The satellites from NASA and other space agencies give us a fresh, wide perspective on things that we can see from the ground – and things that we can’t.
Today, April 22, 2014 is Earth Day, and what better way to celebrate than taking a look at our home planet from space.
Propose a great satnav idea and win a prize with ESA support to create your own business.
Launched on 3 April, ESA’s Sentinel-1A satellite has already delivered its first radar images of Earth.

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...
