and Space Shuttle typically orbit at 350–400 km, within the F-layer of the ionosphere where they encounter enough atmospheric drag to require reboosts every few months. Depending on solar activity, satellites can experience noticeable...

calculate the strength of Saturn's gravity field from data downlinked from Cassini and remove the effect of atmospheric drag from the measurements. 과학자들은 여전히 ​​Cassini에서 다운 링크 된 데이터로부터 토성의 중력장의 강도를 계산하고...

that would essentially shoot puffs of air into the path of orbiting debris. Even that slight increase in atmospheric drag could force junk to fall back to Earth. NASA just gave $1.9 million to Star Technology and Research, a small...

stuff--"moondust." Here on Earth, no one pays much heed to dust or sand blasted out by a rocket launch because "atmospheric drag rapidly slows the lightweight particles so they fall harmlessly to the ground a few meters from the blast...

decay. 3. Aerospace The decrease in orbital altitude of an artificial satellite as a result of conditions such as atmospheric drag. 4. A gradual deterioration to an inferior state: tooth decay; urban decay. 5. A falling into ruin...

doesn't go anywhere near Jupiter. Even at perigee - er, perijove - it's much too high to be affected by atmospheric drag.' 'I've already said enough to get me exiled to my dacha again - and you might not be allowed to visit me next time...

than 1,000 tons, an atmosphere does not slow it down much, though smaller bodies can be substantially slowed by atmospheric drag, as they have a higher ratio of surface area to mass. In any case, the temperatures and pressures on the...

The process uses brief burns from MRO’s thrusters. Those dips have to be deep enough to slow the spacecraft by atmospheric drag … but not deep enough to overheat or damage the orbiter. At aerobraking’s end, MRO’s orbit around Mars...

that is to orbit the Earth is positioned at least 100 miles (160 kilometers) above the Earth's surface so that atmospheric drag will not slow it down. At this height, once it is moving fast enough, the satellite's motion is governed by...
