Yes, the flags from Apollo missions 12, 16, and 17 are still standing on the Moon.
While the flag from Apollo 11 was likely knocked over during the mission's liftoff, subsequent missions took precautions to ensure their flags' survival. These later flags were placed farther away from the lunar module.
Evidence of Remaining Flags
- Lunar Reconnaissance Orbiter (LRO) Images: Images taken by the LRO clearly show that the flags from Apollo 12, 16, and 17 are still intact and casting shadows on the lunar surface. This provides visual confirmation of their continued existence.
Factors Affecting Flag Condition
Despite their survival, the flags have likely suffered some degradation due to the harsh lunar environment:
- Extreme Temperatures: The Moon experiences extreme temperature swings, ranging from scorching heat during the lunar day to frigid cold during the lunar night. These temperature variations can weaken and damage the flag material.
- Ultraviolet Radiation: The Moon lacks an atmosphere to filter out harmful ultraviolet (UV) radiation from the Sun. Prolonged exposure to UV radiation can cause the flag's colors to fade and the fabric to break down.
- Micrometeoroid Impacts: The Moon is constantly bombarded by tiny micrometeoroids. While individual impacts are small, their cumulative effect over decades can cause damage to the flag material.
It's likely the flags are significantly faded and possibly brittle due to these factors. However, the LRO images confirm they are still standing.
