Segment Fifty-One flashed, claiming Friendship 7's heat shield - and time ran out
In this episode, we follow the tense hours of John Glenn's 1962 Mercury-Atlas Six flight from prelaunch delays to a life-or-death sensor reading during reentry. The episode traces the decisions inside Mercury Control and asks whether the team could act fast enough to save him.
Person: John Glenn Glenn
Date: February 20, 1962
Spacecraft: Friendship 7 (Spacecraft Number Thirteen)
Controller: Don Arabian
Mission Directors: Chris Kraft, Walter Williams
- Prelaunch: seven weeks of delays, faulty bolts, ice fog, and a defective hatch that cost forty-two minutes.
- Launch timeline: Glenn entered the capsule at 06:11 ET, ignition at 09:47 ET after multiple scrubs and a heart rate reading of 110 bpm.
- In-orbit: three orbits planned; a small warning appeared on the first orbit and stayed unresolved.
- Critical moment: at 4 hours 33 minutes into flight, Segment Fifty-One lit, indicating the heat shield had unlatched.
- Decision room: Don Arabian reran checks, then Flight Director Chris Kraft and Mission Director Walter Williams confronted the impossible readout.
