Nearly a decade’s worth of data went into the first direct observation of sputtering on Mars, which researchers believe ...

Airplanes undergo stress with each flight from speed, altitude, temperature and atmospheric changes, and more. Learn why TBO ...

"Being off even a little bit represents hundreds or thousands of kilometers in distance on the surface of the Earth." ...

With the arrival of a visiting crew still delayed, science and maintenance work on board the International Space Station ...

Generation of chemical species by atmospheric-pressure plasma treatment of aqueous liquids is a result of reactions at the plasma/gas–liquid interface and subsequent diffusion and convection processes ...

The pressure inside the fairing follows the variation of the atmospheric pressure with the altitude, being slightly higher up to approximately 22 s flight time, when it increases rapidly and reaches a ...

NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E ...

Altitude sickness’ is a set of symptoms that occur when people are at a high altitude, i.e. elevations of about 1,500 metres. It occurs acutely in persons who climb high altitudes and are not ...

During a solar minimum, EUV (extreme ultraviolet) irradiance is lower than it is during more active times in the solar cycle, producing a cooler, contracted thermosphere and decreased density at a ...

Abstract: For pt.I see ibid.(vol.11 no.3 p.481-90, 2004). In order to validate a nonthermal plasma model using nitrogen in a ferroelectric packed-bed reactor, the number density of the excited ...

THE effect of geographical latitude on the semidiurnal wave of atmospheric pressure is fairly regular and well marked, ibut the variation of the diurnal wave has attracted less attention since ...

Atmospheric sputtering is thought to be one of the dominant mechanisms for atmospheric loss in the early Solar System, when the Sun was brighter and more active. It happens when ions are accelerated ...
