Wednesday, May 23, 1962 – Paraglider Wing Wind Tunnel Test


The Ames Research Center has begun the first wind tunnel test of the inflatable paraglider wing, using a half-scale model of the wing intended to bring Gemini flights (after the first one) to a touchdown on the ground. This is the first large-scale paraglider wing in the full-scale test facility. The objective of the test program, to run over two months, are to understand the basic aerodynamic and loads data for the wing and spacecraft system, and to identify potential aerodynamic and design problems.

Monday, May 14, 1962 – Titan II Statement of Work Given


The Manned Spacecraft Center has issued its final Statement of Work for the Air Force Space Systems Division. Space Systems Division is, in this context, contractor to NASA procuring Titan II launch vehicles, as modified for the manned program’s needs. The statement, itemizing the tasks Space Systems Division is expected to do or provide, and on what schedule, and how acceptable performance will be measured, and so on, began being prepared by the Manned Spacecraft Center on January 3. The initial budgeting and planning were completed by the end of March. Though final the plan is subject to amendment.

Friday, May 11, 1962 – Survival kit, biological measurements, spacewalk requirements


A two-day meeting on Gemini crew support systems has identified seven parameters to be measured for determining crew conditions during the Gemini flights. The instruments needed for the highest priority items — blood pressure, electrocardiogram, phonocardiogram, electroencephalogram, respiration, galvanic skin response, and body temperature — would require about three and a half pounds per pilot, require two watt-hours of power, and demand the shared use of six telemetry channels. Approved for development, then, are measurements of the electrocardiogram, respiration rate and depth, oral temperature, blood pressure, phonocardiogram, and nuclear radiation dose.

Tuesday, May 1, 1962 – Digital coding, Gemini rendezvous and radar schemes


A working group made of representatives from Goddard Space Flight Center and the Manned Spacecraft Center has formed to study making Project Gemini telemetry be transmitted fully by Pulse Code Modulation (PCM) systems. This follows a briefing from Lockheed on the system. Pulse Code Modulation is a method of numerical representations of samplings of an original analog signal. Human speech has been transmitted on such systems in experimental equipment as long ago as 1926, and was used — in conjunction with a vocoder, developed by Bell Labs, and with randomized thermal noise recorded by the Muzak Corporation — to provide secure high-level Allied communications during the Second World War.

McDonnell issues a $9 million subcontract to General Electric to design and develop fuel cells for the Gemini spacecraft. The General Electric design, selected by the Manned Spacecraft Center after an analysis completed January 23, appeared to offer advantages over the competing solar cells or other fuel cells in terms of simplicity, weight, and compatibility with other Project Gemini requirements. Much of this advantage is credited to the use of ion-exchange membranes rather than gas-diffusion electrodes within the fuel cells.

The Gemini Project Office made a major decision about seat ejection. It is to be initiated manually, with both seats ejected simultaneously in case either ejection system is energized. The seat ejection is to be useful as a way to escape an emergency while on the launchpad, during the initial phase of powered flight (to an altitude of about 60,000 feet), or on reentry following a failure of the paraglider landing system.

The escape system is to include a hatch actuation system, opening the hatches before ejection; a rocket catapult to shoot both seats away from the spacecraft; and parachutes for the astronauts following their separation from the seat. The system is also to provide for survival equipment for the astronauts to use after landing.

The design is to allow for an automatic initiator in case this later becomes a requirement.

In other news the Manned Spacecraft Center issued its second analysis of the Gemini program schedule. This is the first to consider launch vehicles as well as the spacecraft. (The earlier analysis, of just Gemini operations, was published January 5.) Analysis of the Agena vehicles is limited, as their procurement began only with a request the Manned Spacecraft Center sent to Marshall Space Flight Center on January 31 for the eleven Atlas-Agena rendezvous targets believed needed.

The Gemini program is projected to use a number of test articles for engineering development, correcting a problem which had delayed the Mercury Program at times. The first, unmanned, qualification test is projected for late July or early August 1963. The second, manned, flight is now planned for late October or early November 1963. The first Agena flight is projected for late April or early May 1964. The remaining flights in the program are to be at roughly two-month intervals from then until the middle of 1965.

The Manned Spacecraft Center directed North American to design and develop an emergency parachute system for flight test vehicles.  These vehicles, both half-size and full-size, are required for Phase II-A of the Paraglider Development Program.  The Manned Spacecraft Center authorized North American to subcontract the emergency recovery system to the Radioplane Division of the Northrop Corporation.

The Marshall Space Flight Center composed a procurement schedule for the Agena target vehicles, to be delivered to the Gemini Project Office.

Westinghouse Electric Corporation of Baltimore received a $6.8 million subcontract from McDonnell. Westinghouse will provide the rendezvous radar and transponder system for the Gemini craft. The transponder is to be located in the Agena target vehicle.

Harold I Johnson, head of the Spacecraft Operations Branch (Flight Crew Operations Division of the Manned Spacecraft Center), circulated a memorandum on proposed training devices. The mission simulator should be capable of replicating a complete mission profile including sight, sound, and vibration cues, and be initially identical to the spacecraft, mission control, and remote site displays.

Training for launch and re-entry is to be provided by the centrifuge at the Naval Air Development Center (Johnsville, Pennsylvania), with a gondola set up to replicate the Gemini spacecraft interior. A static article is to serve as egress trainer. A boilerplate spacecraft with paraglider wing, used in a program including helicopter drops, will provide experience in landing on dry land. A docking trainer, fitted with actual hardware, capable of motion in six degrees of freedom, is to be used for docking operations training. And other trainers would be used for prepare for specific tasks.

The first regular business meeting between the Gemini Project Office and McDonnell occurred. Subsequent meetings are scheduled for the Monday, Tuesday, and Friday of each week. The initial coordination meetings had been held February 19, and introduction meetings were held the 19th, 21st, 23rd, 27th, and 28th.  The objective of these meetings is to discuss and settle differences in decision-making about the project.
