Whale Oil as Space Lubricant: Better than Anything We Can Create? #green
But did you know that whale oil was used to send a man to the moon? I learned this weird but true fact during my sea travels...Back in the day, NASA used whale oil as a lubricant in their space program, including the ROV (Remotely Operated Vehicle) for expeditions to the Moon and Mars. Fast forward to the future and whale oil is still being used to lubricate spacecraft such as the Hubble space telescope and the Voyager space probe. Apparently spermaceti--or Sperm whale oil--doesn't freeze in sub-zero temperatures (quite important given space's super-chilly temps) and man hasn't yet found a suitable substitute for the natural lubricant.
