Scene Context: In Mission Control, jars of peanuts are opened before awaiting a critical data packet from the Sagan.
Essence of the Phenomenon: This is not a technical procedure, but a historical ritual. For JPL teams, peanuts have become a symbol of tense waiting periods during major missions.
Scientific Basis: The "lucky peanuts" tradition at JPL has genuinely existed since the Ranger program of the 1960s and has endured for major events like launches, landings, and dangerous maneuvers. Its purpose is psychological, not physical: in a situation where the outcome can no longer be changed, the ritual reduces tension and helps the team endure the wait.
