McDonnell awards a $3.2 million subcontract to Advanced Technology Laboratories, Inc, of Mountain View, California. The subcontract is for the horizon sensor system for the Gemini spacecraft. One primary and one secondary horizon sensor are to be part of the guidance and control system. The sensors are to detect and track the gradient of infrared radiation between the Earth and outer space.

McDonnell also awards a $400,000 subcontract to the Thiokol Chemical Corporation of Elkton, Maryland, for retrograde rockets. The solid-propellant retrorockets, four of which are designed to be put in the adapter section, are to start reentry or, in the event of a high-altitude suborbital abort, separate the spacecraft from the Titan II booster. It is believed that only slight modifications of a motor already in use are necessary, and that the qualification program will not need to be elaborate.

Author: Project Gemini Chronology

The Project Gemini Chronology is drawn from multiple sources, but most heavily from NASA's Special Publication-4002, Project Gemini Technology and Operations: A Chronology, prepared by James M Grimwood and Barton C Hacker, with Peter J Vorzimmer. Other chronologies will be used where fitting, such as (particularly) those for Project Mercury and Project Apollo.
