A high altitude platform can provide observation or communication services. A high-altitude platform station (HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites.
Expanded data set of previous Explorer missions and collected data from Argus high-altitude nuclear explosions. [1] 11.7 kg (25.8 lb) August 17 US: Pioneer 0: Thor-Able 1: Failure: Failed to orbit. First stage engine failure caused explosion at T+77 seconds. 38 kg (84 lb) August 24 US: Explorer 5: Juno I: Failure

The Hawk30 flying-wing is a development of the NASA Pathfinder and NASA Helios high-altitude, long-endurance unmanned aircraft built by AeroVironment for NASA. [2] Resembling the 1999 Helios, the tailless aircraft is a 256 ft (78 m) span flying wing with 10 electric-driven propellers. Orbiting at 65,000 ft (20,000 m), it is solar-powered by day ...
The Zephyr is a series of high-altitude platform station aircraft produced by Airbus. They were designed originally by QinetiQ, a commercial offshoot of the UK Ministry of Defence. In July 2010, the Zephyr 7 flew for 14 days. In March 2013, the project was sold to Airbus Defence and Space. In the summer of 2022, the Zephyr 8/S flew for 64 days.
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
Ground track example from Heavens-Above.An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.
A series of flights were planned to demonstrate that an extremely light and fragile aircraft structure with a very high aspect ratio (the ratio between the wingspan and the wing chord) can successfully take-off and land from an airport and can be flown to extremely high altitudes (between 50,000 feet (15,000 m) and 80,000 feet (24,000 m ...
