The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Images were taken at altitudes ranging from 90–200 mi (480,000–1,060,000 ft; 140–320 km). The camera optical layout is an f/3.0 folded Wright camera, with a focal length of 60 in (1,500 mm). The system aperture is defined by a 20 in (510 mm) diameter aspheric corrector plate, which corrects the spherical aberration of

The U.S. Space Force and a Boeing-Lockheed joint venture sent a secret reconnaissance payload to orbit on Tuesday atop a Delta IV Heavy rocket, the last flight of a workhorse launch vehicle brand ...
It took images of a 6.3° wide ground swath by exposing a 22 cm (8.7 in) wide moving portion of film through a small slit aperture. [6] [7] The initial ground resolution of the satellite was 1.2 m (3 ft 11 in), but improved to 0.6 m (2 ft 0 in) by 1966. Each satellite weighed about 2,000 kg (4,400 lb), and returned a single film bucket per mission.
