# How would humans with appropriate equipment travel the surface of Saturn's moon Titan on foot?

Taking into account the physical characteristics of Titan (e.g. surface gravity, atmospheric pressure), what would be the most efficient method of motion for an astronaut to travel the surface of Titan on foot?

Would it be a leaping or hopping motion? Or would it make more sense to walk somehow? I'm unsure how the friction of the ground would accommodate for that.

For the purpose of this thought experiment, lets assume that humanity has the necessary equipment to put an astronaut on Titan and to have protective clothing to enable reasonable safety from environmental hazards on the surface.

For further clarification, the gravity is a comfortable 1.352 m/s2 (0.14 g in comparison with Earth) which equates to .85 Moons. The surface pressure is 146.7 kPa which compares to 1.45 atm (Earth).

In terms of efficiency, it would come down to how much work the human body would have to do to result in an "optimal" speed, by always considering the safety of humans traversing the landscape first and foremost.

• The surface gravity of the Titan nears the Moon, so what we would see is like we could see on the Moon landing wideos of the 70s. – peterh - Reinstate Monica Dec 14 '18 at 13:26
• +1 Great question! I've swapped in "travel" where you had "navigate" because navigation is an excellent but different question than what you are asking. I almost started writing an answer explaining how they could literally navigate their way around. In fact; Why not consider posting a second question asking for various methods they might use to actually navigate their way from point A to point B if (for example) they didn't have a suitably detailed and updated map? – uhoh Dec 14 '18 at 13:45
• Not sure if travelling by foot would be the most efficient way to move on Titan. Human powered flight could be very much faster and fun. – qq jkztd Dec 14 '18 at 13:51
• @peteh the temperature is three times lower, so the density will be about 5 times that of Earth. I don't know about the viscosity, but given that you also have only aboyut 1/7 the weight to give you traction, I think there might be a real risk that you push off the ground and instead of a long hop or glide as you'd get on the Moon, you would come to a stop pretty quickly (like a thrown party balloon) and slowly fall back to the ground. I might be wrong, but I don't think it's obvious either way. – Steve Linton Dec 14 '18 at 14:30
• The flight thing sounds fun, however the lower gravity of Titan will be entirely countered by the weight of all the equipment the human needs for Titan to not kill her. – Mark Adler Dec 14 '18 at 20:43
