It was conceived for the purpose of dictation but gained popularity with the general public after its use during the Apollo program lunar missions. It was released commercially in 1968. Sony TC-50 cassette tape recorder on display at the Houston Space Center. NASA furnished every astronaut with a Sony TC-50 from Apollo 7 in 1968 onward. [1]
Apollo Command Module primary guidance system components Apollo Lunar Module primary guidance system components Apollo Inertial Measurement Unit. The Apollo primary guidance, navigation, and control system (PGNCS, pronounced pings) was a self-contained inertial guidance system that allowed Apollo spacecraft to carry out their missions when communications with Earth were interrupted, either as ...
The docking mechanism of the Apollo was a "probe and drogue" system designed to allow the Apollo Command/Service Module (CSM) to dock with the Apollo Lunar Module.The same system was later used for the Skylab 2, Skylab 3 and Skylab 4 CSMs to dock with the Skylab space station, and the Apollo–Soyuz Test Project CSM to dock with a Docking Module adapter which allowed docking with the Soyuz 19 ...
This crewed flight was to have followed the first three uncrewed flights. After the fire which killed the AS-204 crew on the pad during a test and training exercise, uncrewed Apollo flights resumed to test the Saturn V launch vehicle and the Lunar Module; these were designated Apollo 4, 5 and 6. The first crewed Apollo mission was thus Apollo 7 ...
The Apollo flight computer was the first computer to use silicon IC chips. [15] While the Block I version used 4,100 ICs, each containing a single three-input NOR gate, the later Block II version (used in the crewed flights) used about 2,800 ICs, mostly dual three-input NOR gates and smaller numbers of expanders and sense amplifiers.
Margaret Elaine Hamilton (née Heafield; born August 17, 1936) is an American computer scientist.She directed the Software Engineering Division at the MIT Instrumentation Laboratory, where she led the development of the on-board flight software for NASA's Apollo Guidance Computer for the Apollo program.
To conform to these regulations the gate system must be checked with a calibrated force tester and the full results kept in a technical file for 7 years. If the gate is not tested it does not comply. Most gate kits can be fitted with safety equipment so that these limits are achieved and so cover that part of EN13241-1.
