An out-of-control satellite has fallen to Earth, nearly three decades after it launched. ... The predicted time for the satellite entering the Earth’s atmosphere was originally 3.49pm GMT (10.49 ...
Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of ...
The Southern Taurids meteor shower will enter its peak on Monday night — and people across the world can view it at midnight local time Taurid Meteor Shower Entering Earth's Atmosphere This Week ...
Expired satellites add to the clutter as they stay in orbit until they fall into - and burn up in - Earth's atmosphere years later or are flown to a "graveyard orbit" some 36,000 km away.
Objects which enter and then leave Earth's atmosphere, the so-called Earth-grazers, are a distinct phenomenon, inasmuch as entering the lower atmosphere can constitute an impact event rather than a close pass. Earth-grazer can also be short for a body that "grazes" the orbit of the Earth, in a different context.
Communications satellites are a vital part of global commerce. Weather satellite systems provide information about terrestrial weather. The signals from satellites of a global positioning system (GPS) are used in a wide variety of applications. Space weather phenomena can interfere with or damage these satellites or interfere with the radio ...
Due to the sheer number of satellites expected to fly, die, and re-enter in coming years, future mega-constellations could inject 21 times more aluminum oxides into the upper atmosphere than 2022 ...
Project Space Track began its history of satellite tracking from 1957–1961. Early Space Track observations of satellites were collected at more than 150 individual sites, including radar stations, Baker–Nunn cameras, telescopes, radio receivers, and by citizens participating in the Operation Moonwatch program. Individuals at these Moonwatch ...
