- Did the Mars rovers actually confirm the gravity of Mars?
The gravity on mars is theoretically calculated to be 0 3895 of the earths gravity The earths gravity is expressed in SI units as 9 80665 m s2 Mars is theoretically calculated at 3 728 m s2 I'm asking if this theoretical value was confirmed by the rover
- mars - History of investigation of lunar and Martian surface gravity . . .
So gravity of Moon and Mars could be estimated decades before the space age but with very limited precison From Wikipedia's Pierre-Simon Laplace: Laplace's tidal equations In 1776, Laplace formulated a single set of linear partial differential equations, for tidal flow described as a barotropic two-dimensional sheet flow
- Does lower gravity on Mars make it unsafe and unhealthy for humans . . .
However, there's one problem, and that is gravity Gravitational acceleration on Mars is 38% of what it is on Earth Does lower gravity on Mars make it unsafe and unhealthy for humans?
- Will a human mission to Mars require artificial gravity?
Given that we know similar durations of weightlessness aren't deadly and can be recovered from, if you were designing a mission to Mars that couldn't use artificial gravity for some reason, presumably you'd tailor the surface mission objectives to allow that to work I think you'd have to add additional constraints for artificial gravity to be a requirement
- Is Mars gravity strong enough to hold a human-breathable atmosphere . . .
It's a weaker gravity field, but remember, Mars once had a thick atmosphere similar to Earth's, and it held onto that atmosphere for millions and millions of years with the exact same gravity field The problem with Mars is this: it doesn't have a magnetic field to shield the atmosphere from the energetic solar wind, which can then easily break down water molecules into oxygen and hydrogen
- How would travel to Mars without artificial gravity affect a crews . . .
note: One could use an external mass and tether for a more uniform artificial gravity, but that's a separate issue After a flight to Mars with no artificial gravity, what would the initial experience be like after landing? With no ground crew to assist, would the crew simply sit there for a while, then slowly start moving and assisting each other? Would robotic assistance be particularly
- mars - How much gravity is actually needed to avoid serious health . . .
But is that really necessary? Have there been any studies or research into how much gravity is actually needed in order to minimize the long-term health effects? A spaceship that rotates to generate 1g of gravity would either require a (debatably) impractically long tether, or have to spin so fast that it would cause a disorienting Coriolis effect
- gravity - Will a Palm tree on Mars be approximately 2. 5 times taller . . .
Surface gravity on Mars is about $3$ times weaker than on Earth, but atmospheric pressure is about $150$ times less So the maximum height of a column of water maintained only by negative pressure is about $50$ times smaller
