Ongoing tensions between the US and Russia have left the US Air Force (USAF) scrambling for alternatives to Russian-built rocket engines, but could pay off big for some American companies in the long run.

On Tuesday, Deputy Prime Minister Dmitry Rogozin said Russia would not agree to continue operating the International Space Station (ISS) beyond 2020. US officials have stated that they would like the ISS collaboration to last until at least 2024.
Microsatellite Market majorly focuses on solutions, masses, applications, verticals, & regions.
Space debris, or space junk, is a pressing problem for humanity both in space and on the ground. The problem is so relevant that a recent movie starring Sandra Bullock and George Clooney has not only featured a devastating encounter in space
CD Reissue And Digital LP Include Two Previously Unreleased Early Studio Demos NEW YORK, May 7, 2014 /PRNewswire/ -- On June 17, Bama Rags/RCA/Legacy Recordings will reissue Dave Matthews
Oklahoma’s site for the 2014 NASA International Space Apps Challenge releases winners for global and local recognition. Oklahoma City, OK (PRWEB) April 30,
Europe’s latest Galileo navigation satellite has arrived at the Agency’s technical center in the Netherlands for testing, as the previous two satellites are prepared for shipping to French Guiana for launch this summer.
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.
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...
