- Project Mercury was initiated as a fast and simple response to the Soviet lead in space exploration after Sputnik.
- The challenge of safely returning astronauts to Earth led to the use of oceans for splashdowns, requiring capsules to float and be locatable.
- Early space capsules were equipped with SOFAR bombs, designed to explode underwater in the SOFAR channel to help locate the capsule via sound waves.
- The SOFAR channel is a deep ocean layer where sound travels efficiently over long distances due to temperature and pressure effects.
- SOFAR bombs had a dual purpose: aiding in capsule recovery and destroying sensitive technology to prevent Soviet acquisition.
- Despite initial success, SOFAR bombs were eventually phased out in favor of more reliable technologies like radio beacons and GPS.
- Project Mercury exemplifies early spaceflight's innovative and pragmatic approach, despite some near-misses and challenges.
