The Redstone Test Stand or Interim Test Stand was used to develop and test fire the Redstone missile, Jupiter-C sounding rocket, Juno I launch vehicle and Mercury-Redstone launch vehicle. It was declared an Alabama Historic Civil Engineering Landmark in 1979 [ 3 ] and a National Historic Landmark in 1985. [ 2 ]
In computability theory, a system of data-manipulation rules (such as a model of computation, a computer's instruction set, a programming language, or a cellular automaton) is said to be Turing-complete or computationally universal if it can be used to simulate any Turing machine [1] [2] (devised by English mathematician and computer scientist Alan Turing).
The most important change in making the Mercury-Redstone a suitable vehicle for an astronaut was the addition of an automatic in-flight abort sensing system. [11] In an emergency where the rocket was about to suffer a catastrophic failure, an abort would activate the launch escape system attached to the Mercury capsule, which would rapidly ...
Shepherdson & Sturgis (1963) observe that "the proof of this universality [of digital computers to Turing machines] ... seems to have been first written down by Hermes, who showed in [7--their reference number] how an idealized computer could be programmed to duplicate the behavior of any Turing machine", and: "Kaphengst's approach is interesting in that it gives a direct proof of the ...
The "PC Word" register is split in half; the right 18 bits contains the program counter and the left 13 bits contains the processor status flags, with five zeros between the two sections. The condition register bits, which record the results of arithmetic operations ( e.g. overflow), can be accessed by only a few instructions.
Subsequent test flights went better and the Army declared Redstone operational in mid-1955. Testing was moved from LC-4 to the bigger LC-5 and LC-6. The Redstone program proved to be a bone of contention between the Army and Air Force due to their different ideas of nuclear warfare.
Internally, the program counter is twelve bits wide, and there are separate instructions to set the upper four bits by copying an 8-bit value into the high byte. This provides a memory map of sixteen four-kilobyte pages, and program code could not refer to code or immediate or PC-relative data outside its own page. [6]
U.S. Army Redstone Test Center, or RTC, is subordinate organization to the United States Army Test and Evaluation Command, [1] a direct reporting unit of the United States Army responsible for developmental testing, independent evaluations, assessments, and experiments of Army aviation, missiles and sensor equipment.
