Above the Earth’s surface there are many orbital planes and no pesky oceans to prevent millimeter and centimeter-sized cars from being spaced out there. This gives a rough idea of just how ...

Scientists are baffled after the UK's oldest satellite, Skynet-1A, which dates back to 1969, moved to an entirely different ...

Someone moved the UK's oldest satellite and there appears to be no record of exactly who, when or why. Launched in 1969, just ...

Like orbital mechanics on an early 80s Kaypro, perhaps? At least that’s the hurdle [Chris Fenton] set for himself as a fun project for his spare time with his Kaypro 2/84, a vintage Z80 ...

This is compared with the time frame of Newton's work on his second law, the law of gravitational attraction and calculus from the late 1600's. Kepler was able to arrive at this second law without the ...

Designed to include recent developments in space exploration (e.g. Galileo, Cassini, Mars Odyssey missions), this reference guide covers basic aspects of orbital mechanics, from celestial ...

Providing an overview of the basic mission considerations for spacecraft design, this authoritative text offers the tools to evaluate the overall impact of candidate design concepts on the various ...

In atomic theory and quantum mechanics, an atomic orbital is a mathematical function describing the location and wave-like behavior of an electron in an atom. This function can be used to calculate ...
