How does Jason move around?
Jason drops to the sea floor at a rate of about 30 meters (100 feet) per minute. Six electric thrusters propel it forward, backward, sideways, up or down at a top speed of 2.8 kph (1.5 knots). When sampling, the top speed drops to 0.37 kph (0.2 knots). Medea doesn’t move around on its own, but the ship can tow it slowly through the water to keep up with Jason.
