How would swimming on Mars feel, given the lower gravity?

There's one consideration probably neglected by most answers: with water viscosity unchanged, it will be much easier to remain on/above the surface through actively "pushing against the water" - ...

Will colonists on Mars have enhanced physical mobility relative to an Earth-normal environment?

The initial velocity assumption in TidalWave's answer is incorrect. The maximum initial velocity value is calculated from the accelerating force (muscle work) minus the decelerating force (gravity) ...

At what surface gravity can't astronauts do full steps anymore?

Short answer: You would transition to running at what is a comfortable walking speed on Earth, and movement would take about half of the energy it does on Earth (Source 1). This does not take into ...

With so little gravity, would swimming on Enceladus be feasible for humans?

Sure. Whatever the pressure-based limit is, they can dive proportionally deeper by the amount that the gravitational acceleration is less. For Enceladus, that would be 87 times deeper. The pressure is ...

How far can you fall on the Moon without injury?

Although this question has many answers already, I thought I'd add a more general answer How far could a human fall in a pressurised environment on various solar system bodies? I'm imagining that ...

Does ISS crew exercise time count toward their X hour work week?

No, exercise time is not part of the "40 hour" work week. From the question you linked to: 06.00 wake up, breakfast 07.30 planning conference 08.15 start of the work day: science and maintenance ...

How far can you fall on the Moon without injury?

I would like to add that there is no real definite "fatal" velocity at the point of impact. It is much easier to suffer a fatal fall resulting from damaged life-support equipment in a spacesuit on ...

Do astronauts aboard the International Space Station (ISS) actually use their legs?

Do astronauts use their legs in Space? Yes, astronauts use their legs daily as they have to work out about 2 hours a day to combat bone loss and other negative health effects that microgravity has on ...

Do astronauts aboard the International Space Station (ISS) actually use their legs?

It is worth noting that in the 2021 recruitment process, ESA is also looking for astronauts with physical disabilities, including: Persons who have a lower limb deficiency (e.g. due to amputation or ...

Does gravity affect sweating?

Sweat production depends on the activity level, clothing and air temperature. Defining a test activity with exactly the same workload on Earth and in zero gravity in orbit is very difficult. You ...

Does prolonged space flight have any effect on the physical traits of the human body?

There is a Wikipedia article dedicated to the effects of spaceflight on the human body. Some of this is about launch and other aspects outside "prolonged space flight". Still, you might want to see ...

How would swimming on Mars feel, given the lower gravity?

Wave height will be bigger, right? And of course, droplets and splashes will take longer to fall. As your head leaves the water, surface tension will try to hold water blobs onto your face, which ...

How far can you fall on the Moon without injury?

Earths gravity is 6 times stronger than the moon. You can jump from a height 6 times higher on the moon. Most people would not want to jump from a height of more than 2 metres on earth. Therefore you ...
