The Lens Cap That Turned a Venus Landing into a Plastic Experiment
On March 5, 1982, the Soviet Venera 14 lander touched down on Venus, ejected its camera lens cap, and, after photographing the surroundings, lowered its mechanical soil-testing arm onto the discarded cap—yielding a measurement of the cap’s plastic compressibility rather than Venusian rock. The piece uses this mishap to illustrate how Venera’s design aimed to survive Venus’s extreme conditions and how the mission’s data still informs later NASA missions like DAVINCI and VERITAS, making it a notable episode in space exploration history.
