Oh, how I miss the wind on my face, the feeling of raindrops, sand on my feet and the sound of the surf crashing on the Galveston beach, we take daily sensory inputs for granted until they are absent. The environmental inputs on the space station consist mostly of the constant hum of the ventilation system. It stirs the air, allowing the purification system to scrub and clean our atmosphere so it's breathable. While some places on the space station are as loud as a lawn mower, others are as quiet as the vacuum of space. I can not wait to feel and hear Earth again.
