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.
In the case of Earth this includes all space from the Earth to a distance of roughly 1% of the mean distance from Earth to the Sun, [116] or 1.5 million km (0.93 million mi). Beyond Earth's Hill sphere extends along Earth's orbital path its orbital and co-orbital space.
It communicates through the NASA Deep Space Network (DSN) to receive routine commands and to transmit data to Earth. Real-time distance and velocity data are provided by NASA and JPL. [4] At a distance of 166.28 AU (24.9 billion km; 15.5 billion mi) from Earth as of December 2024, [4] it is the most distant human-made object from Earth. [5]
A view from the International Space Station in a low Earth orbit (LEO) at about 400 km (250 mi), with yellow-green airglow visible at Earth's horizon, where roughly at an altitude of 100 km (62 mi) the boundary between Earth and outer space lies and flying speeds reach orbital velocities.
380 Earth radii (very inaccurate, true=16000 Earth radii) Aristarchus of Samos made a measurement of the distance of the Sun from the Earth in relation to the distance of the Moon from the Earth. The distance to the Moon was described in Earth radii (20, also inaccurate). The diameter of the Earth had been calculated previously.
Orion took the snapshot around its maximum distance from Earth of 268,563 miles. That's the farthest any human-oriented spacecraft has traveled, beating even Apollo 13's record of 248,655 miles ...
Nasa has received a signal from a spacecraft 10 million miles away.. The message, delivered using a distant laser, could “transform” communications with spacecraft, the space agency has said ...
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]
