Not only did the piece of wood come from the apple tree that inspired Isaac Newton to develop his theory of gravity, but wood is also useful in space. White oak tiles performed admirably as a heat shield on a Chinese recoverable satellite. The tiles developed a layer of insulating char which impeded heat flow into the vehicle while it was entering Earth’s atmosphere. Balsa wood was used as a crushable impact attenuator to protect delicate components such as transmitters when spacecraft were deliberately crash-landed on the moon. Who knows what uses might be found for apple wood?
