Where space begins ... can actually be determined by the speed of the space vehicle and its altitude above the Earth. Consider, for instance, the record flight of Captain Iven Carl Kincheloe Jr. in an X-2 rocket plane. Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up.
These MeV-energy Compton electrons then accelerate and spiral along the Earth's magnetic field lines. The resulting transient electric fields and currents generate electromagnetic emissions in the radio frequency range of 15 MHz to 250 MHz. This high-altitude EMP occurs between 30 and 50 kilometers (19 and 31 miles) above the Earth's surface.
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).
The team of college students broke the world record for the highest altitude reached by a rocket launched by amateurs — soaring a whopping 89 miles above the Earth. USC Rocket Propulsion Lab
Transatmospheric orbit (TAO): geocentric orbits with an apogee above 100 km and perigee that intersects with the defined atmosphere. [4] Very low Earth orbit (VLEO) is defined as altitudes between approximately 100 - 450 km above Earth’s surface. [5] [6] Low Earth orbit (LEO): geocentric orbits with altitudes below 2,000 km (1,200 mi). [7]
From blue comets and pink northern lights to snowy volcanos and winding rivers, the view 250 miles above Earth does not disappoint. Here are the best photos of 2024 from the space station.
Within this oval-shaped orbit, the satellite will alternately swing out to 22,300 miles (35,890 km) high and then back down to an altitude of only 100 miles (160 km) above the Earth (223 times closer). Then, at a planned time and place, an attached "kick motor" will push the satellite out to maintain an even, circular orbit at the 22,300-mile ...
A wide variety of sources [5] [6] [7] define LEO in terms of altitude.The altitude of an object in an elliptic orbit can vary significantly along the orbit. Even for circular orbits, the altitude above ground can vary by as much as 30 km (19 mi) (especially for polar orbits) due to the oblateness of Earth's spheroid figure and local topography.
