There can be cases of multiple bonds too. Consider ethylene (C2H4). Carbon has 4 valance electrons and hydrogen has one. The two carbon atoms share two electrons each, while each shares another ...

If you're in search for an orbital sander, there's a good chance that you are trying to smooth out some wood. Though, the tool does a lot more than just that, and in the process becomes a ...

Reflect Orbital plans to deploy 57 small satellites into low-Earth orbit. Each satellite will be outfitted with a 33-square-foot reflective Mylar mirror. These mirrors are designed to reflect ...

This centripetal force must be supplied by gravity which is also related to the radius of the orbit. So the trick is to find an orbital radius which works out to give a period of 24 hours. Can it be ...

NASA aims to travel to the moon again—and beyond. Here’s a look at the 21st-century race to send humans into space. Private spaceflight is not a new concept. In the United States, commercial ...

Its last launch—which carried the first 18 Qianfan satellites—broke up into a cloud suspected to number more than 700 pieces of orbital debris. SAST has so far not responded to requests for ...

In context: Boeing and NASA began developing the first Orbital Test Vehicles in the X-37 series in 1999, with the first X-37 drone entering service in 2010. Now managed by the US Air Force Space ...

The graph shows how the orbital speed of a planet changes with its distance from the Sun. Polar orbits take the satellites over the Earth’s poles. The satellites travel very close to the Earth ...

To manage the hazards of orbital debris, we will need continuous monitoring and improved tracking technology alongside deliberate efforts to minimize the amount of debris. Most satellites are much ...
