Question 1

From NASA.gov's STS-51B: Mission Highlights The primary payload was Spacelab-3. This was the first operational flight for the Spacelab orbital laboratory series developed by the European Space Agency....

Question 2

While the astronauts were still in orbit preparing for atmospheric reentry there was already a clear acceleration noticeable. I'm linking to one of the many YouTube copies of the original X live ...

Question 3

I'm familiar with $F_{g} = G\frac{m_{1}m_{2}}{r^{2}}$ and I was wondering if that means anyone orbiting the Earth actually experiences greater perceived weightlessness due to orbit itself compared to ...

Question 4

Would there be different effects on the human body (physiology, chemistry, psychology, other) over long periods of time if there was very very low gravitational field acting on it instead of being in ...

Question 5

In the story I currently write, I have a character who has been a passionate swimmer for decades. Now, she goes to space. I wonder how she would adapt to weightlessness, and would her swimming ...

Question 6

I heard a claim that a piece of graphite, of half a millimeter size which broke from a pencil can kill a person who inhales it. Is this a major problem or an exaggeration? In a gravitational ...

Question 7

There are three types of trajectories which produce microgravity but intersect with the surface of the earth: Reduced Gravity Flights in airplanes. These are sometimes called “parabolic” but are ...

Question 8

To experience "weightlessness" without actually traveling into space, and orbiting the earth, a parabolic flight is used. See the flight path of Mercury, as shown in this link: https://en....

Question 9

As I was watching Ad Astra (Great movie, but where does the gravity come from?), I had the idea that in a building or closed vehicle in a low gravity location, maybe air pressure could be used to ...

Question 10

Dust and small particles in microgravity environments are generally regarded as bad, and items prone to generating these tend to be discouraged: Bread should be prepared quite differently, so that it ...

Question 11

A comment under this question states that "A good smack of a hammer" - is not a simple thing in zero gravity. You need a special hammer with absorption of inertia. Why is this the case? ...

Question 12

This answer to What are the main impacts on the body of an astronaut exposed to long term zero gravity? mentions that the increase in bone loss due to extended periods of time in microgravity can not ...

Question 13

Is the gravity pull of the Earth negligible at 50 miles up, or is the weightlessness experience just relative to a falling airframe? https://en.wikipedia.org/wiki/Reduced-gravity_aircraft

Question 14

This just blew me away: What Is Microgravity? The page says the reason astronauts (in the International Space Station, ISS) experience microgravity is not because they're in "space" but ...

Question 15

The two articles below describe a set of plasma crystal experiments scheduled for 2019 aboard the ISS in cooperation with German and Russian scientists on the ground. These were not the first but ...

Is perceived weightlessness greater in orbit due to constantly falling?

Could there be a difference to the human body between Low Earth Orbit “zero G” microgravity and midway between planets weak gravitational fields?

Does swimming experience help to adapt to weightlessness?

On space stations, what do they do with small solid particles which are free floating?
