The Viking program grew from NASA's earlier, even more ambitious, Voyager Mars program, which was not related to the successful Voyager deep space probes of the late 1970s. Viking 1 was launched on August 20, 1975, and the second craft, Viking 2, was launched on September 9, 1975, both riding atop Titan IIIE rockets with Centaur upper stages.
Inforex Inc. corporation manufactured and sold key-to-disk data entry systems in the 1970s and mid-1980s. The company was founded by ex-IBM engineers to develop direct data entry systems that allowed information to be entered on terminals and stored directly on disk drives, replacing keypunch machines using punched cards or paper tape, which had been the dominant tools for data entry since the ...
Schematic of the Viking Lander Biological Experiment System. In 1976 two identical Viking program landers each carried four types of biological experiments to the surface of Mars. The first successful Mars landers, Viking 1 and Viking 2, then carried out experiments to look for biosignatures of microbial life on Mars. The landers each used a ...
The system can be integrated with the launchers of the Antey 2500 complex, increasing its range from 65 to 130 km. [132] The "Viking" is reported to be able to operate both autonomously and in cooperation with other air defence systems, using their radar data for targeting, and have a gap of 20 seconds between stopping and launching missiles.

YS-3A prototype S-3 escape system testing. In the mid-1960s, the United States Navy (USN) formulated the VSX (Heavier-than-air, Anti-submarine, Experimental) requirement, which sought a dedicated anti-submarine aircraft capable of flying off of its aircraft carriers as a replacement for its existing inventory of piston-engined Grumman S-2 Trackers.
Viking 1 was the first of two spacecraft, along with Viking 2, each consisting of an orbiter and a lander, sent to Mars as part of NASA's Viking program. [2] The lander touched down on Mars on July 20, 1976, the first successful Mars lander in history.
