Germany blocks full Chinese takeover of satellite startup

Germany has blocked a complete Chinese takeover of a satellite startup on national security grounds, sources close to the matter told AFP Thursday, as Berlin takes an increasingly hard line against Beijing.

We could soon be getting energy from solar power harvested in space

The idea of space-based solar power (SBSP)—using satellites to collect energy from the sun and "beam" it to collection points on Earth—has been around since at least the late 1960s. Despite its huge potential, the concept ...

In physics, an orbit is the gravitationally curved path of one object around a point or another body, for example the gravitational orbit of a planet around a star.

Historically, the apparent motion of the planets were first understood in terms of epicycles, which are the sums of numerous circular motions. This predicted the path of the planets quite well, until Johannes Kepler was able to show that the motion of the planets were in fact elliptical motions.[citation needed] Isaac Newton was able to prove that this was equivalent to an inverse square, instantaneously propagating force he called gravitation.[citation needed] Albert Einstein later was able to show that gravity is due to curvature of space-time, and that orbits lie upon geodesics. This is the current understanding.
