Project Mercury

Download file to see previous pages... During the period the project was active 25 space flights were completed where six of the missions were manned flights. Those six manned flights were completed with an excellent pilot safety record and with no deviation from the Mercury program basic operating parameters (Nasa). The Mercury project outlined a series of operational objectives to be completed: 1. To launch a manned space flight mission in orbit around the earth. 2. To investigate and analyze man’s capabilities and ability to function in a zero g space environment. 3. To safely land the spacecraft and recover the pilot successfully. After establishing the primary objectives, certain guidelines were put in place in order to guarantee the most efficient and safest approach to completing the mission objectives. The guidelines established were as follows: 1. Existing off the shelf the shelf technology must be used whenever possible. 2. General system design should follow a philosophy of safety and simplicity. 3. A current launch vehicle platform will be utilized to safely place the spacecraft in orbit.
