Geostationary orbits are ideal for weather satellites and communications satellites. In general, the higher the orbit, the longer the satellite can stay in orbit. At lower altitudes, a satellite runs into traces of Earth's atmosphere, which creates drag. The drag causes the orbit to decay until...
A pair of sunglasses seems so simple -- it's two pieces of tinted glass or plastic in some sort of plastic or metal frame. How much more straightforward can something get? It turns out that there are many different things you can do with two pieces of glass, and these things can have...
This variation in local time explains why some Starlink satellites decayed while others did not. This viewpoint can also explain the connection between the influence of a magnetic substorm and the deterioration of numerous Starlink satellite orbits. An interesting study found that the magnetic storms ...

"Sunlight at the Martian equator is about equal to that of Norway," Zubrin said. "And there's also nitrogen and all the other elements needed to make fertilizers and so forth." Iron oxide and silicon oxide are also common in Martian soil, so human pioneers would be able to make iron,...
In some cases, they are globs of rubble, commandeered by the orbits of planets they drew too close to. Others, like our own moon, are remnants from the primeval collisions of ancient objects. Ours was the “first” moon. Early civilizations clocked its myriad changes—its changing shape, ...
How are the ionization energies evidence for the structure of the atom, especially the electron configurations for atoms? In Bohr's model the position of the electron... a. is not constrained. The electron may be found anywhere outside of the nucleus. b...
The Zeffectie is defined as the net positive charge experienced by an electron in an atom having more than one electron. In fact, the electrons in the inner orbits shied the positive charge to be experienced by the electron at the outermost orbit. Therefore, we usually talk ...
look at how much a star's light dims when a planet passes across the face of it, from the perspective of Earth. If the system is close enough to Earth, and the planet is big enough, sometimes astronomers can see a difference in the elements of the star when the planet orbits in ...
different, though not as drastically different in composition as you might assume. Earth's atmosphere is composed of 78% nitrogen gas (N2) and 21% oxygen gas (O2). The final 1% is a mix of argon, carbon dioxide, neon, helium, methane, krypton, and many other gasses in minor quantities...
