Air-independent propulsion. Air-independent propulsion ( AIP ), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel ). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
Atmospheric circulation. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant.
Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1] : 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and ...
A low Earth orbit ( LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. [1] Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around 800 km (500 mi), [2] while the farthest in LEO, before medium Earth orbit (MEO ...
Atmospheric methane is the methane present in Earth's atmosphere. [2] The concentration of atmospheric methane is increasing due to methane emissions, and is causing climate change. [3] [4] Methane is one of the most potent greenhouse gases. [5] : 82 Methane's radiative forcing (RF) of climate is direct, [6] : 2 and it is the second largest ...
In this method, the attacking aircraft directs a narrow beam of radar energy at the target. The air-to-air missile was launched into the beam, where sensors on the aft of the missile controlled the missile, keeping it within the beam. So long as the beam was kept on the target aircraft, the missile would ride the beam until making the interception.
Contrail. Contrails ( / ˈkɒntreɪlz /; short for " con densation trails ") or vapor trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several kilometres/miles above the Earth's surface. They are composed primarily of water, in the form of ice crystals.
Scientists found a new way to degrade PFAS, a class of "forever chemicals" that is nearly impossible to destroy.
