Mars has a mass of 6,419 · 1023 kg. Compared with Earth this is only a little bit more than a tenth. This results in a lower Gravity.
The gravitational acceleration is only 3,71 m/s². The resulting weight of any body on the surface of Mars is only a bit more than a third, compared with the same body on Earth.
That takes us up to the next level. Great posintg.
Impact on humans
The development of human embryos might be different. Also, the long term consequences for the health of human beings is unclear. Some kind of physical exercise can be helpful.
Impact on technology
- The pressure on bearings is lower, causing less friction and abrasion.
- A space elevator is easier to build.
Open issues
- What is known about the growth of plants under low gravity?
