Earth's atmosphere photographed from the International Space Station.The orange and green line of airglow is at roughly the altitude of the Kármán line. [1]The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space; it is widely but not universally accepted.
Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [120] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
Stability means that satellites in DRO do not need to use station keeping propellant to stay in orbit. The lunar DRO is a high lunar orbit with a radius of approximately 61,500 km. [24] This was proposed [by whom?] in 2017 as a possible orbit for the Lunar Gateway space station, outside Earth-Moon L1 and L2. [20]
The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [10] is a proposed conventional boundary between Earth's atmosphere and outer space. Until the middle of the 20th century, which was considered the pioneering time of aviation, there were no fixed boundaries as to what was national airspace and when it became international ...
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of over 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
The Kármán line, at 100 km (62 mi) or 1.57% of Earth's radius, is often used as the border between the atmosphere and outer space. Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 km (75 mi).
The V-2 No. 13 [1] was a modified V-2 rocket that became the first object to take a photograph of the Earth from outer space. [2] [3] Launched on 24 October 1946, [4] at the White Sands Missile Range in White Sands, New Mexico, the rocket reached a maximum altitude of 65 miles (105 km). [1] [5]
Similar to skydiving, space diving is the act of jumping from an aircraft or spacecraft in near space and falling towards Earth. The Kármán line is a common definition as to where space begins, 100 km (62 mi) above sea level.
