- Apollo 15 Hammer-Feather Drop (youtube.com)
At the end of the last Apollo 15 moon walk, Commander David Scott (pictured above) performed a live demonstration for the television cameras. He held out a geologic hammer and a feather and dropped them at the same time. Because they were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer, as Galileo had concluded hundreds of years before - all objects released together fall at the same rate regardless of mass.

The Chuckanut Mountains (from “Chuckanut”, an indigenous word meaning “long beach far from a narrow entrance”), or Chuckanuts, are located along the Washington state coast of the Salish Sea, just south of Bellingham, Washington. Part of the Cascade Range, they are the only place where the Cascades come west down to meet the sea. The Chuckanuts are considered to be a part of the Puget Lowland Forest Ecoregion.
