Tighten up your space undies!
Here's one for SPACE FANS:
The attached LinkedIn article has Aussie scientists squeezing astro-nuts (not a misspelling) into tighter undies. Can you feel the gravity of this? How do we solve the issue of the deterioration of human biology in low gravity space? Are we ready to exploit the wealth of space?

3 RPM + 1KM - pay attention to this simplified algorithm, because it's quite probably the future of space.
Seeing this simple intellectual person's algorithm as the original intellectually rich person's NEWTON's LAW goes like this:
NEWTON DROPS THE APPLE... and finds this:
Newton's universal law of gravitation: F = Gm1m2/r2, where F is the force due to gravity, between two masses (m1 and m2), which are a distance r apart; G is the gravitational constant.
Earth:
Average surface gravity is about 9.8 meters per second per second. When an object is tossed off a building top or a cliff apex, for instance, it accelerates toward the ground at 9.8 meters per second per second.
Moon:
Surface gravity is about 1/6th as powerful or about 1.6 meters per second per second.
AND
Newton's law of gravitation applied to EARTH is:
F = GMm r2 where the Gravitational Constant G = 6.673 × 10−11Nm2kg−2 (kg−1m3s−2). gravitational force per unit mass = gravitational acceleration g. g is approximately 9.8m/s2 at the surface of the Earth.
And so, the answer is simple, yet HUGE.
Centrifugal force can be created to generate artificial gravity, by spinning a space craft at 3 RPM (revolutions per minute) and making the craft longitudinally one kilometre long.
Sound impossible?
Here's another simple person's algorithm.
LEO + $$$
The main barrier to engineering in space is the cost per weight to get cargo into LOW EARTH ORBIT or LEO, which can cost from astronomical prices to galactic empire prices.
Check out the PAYLOAD COSTS source link below to satisfy your curiosity for how much it costs to send space freight. Get used to that concept. SPACE FREIGHT. Civil engineering industry is about to take off, and soon enough, you could be a SPACE EXECUTIVE, managing SPACE LOGISTICS.
Space mining begins on the moon.
With one sixth of the gravity of earth, engineering on and shipping from the moon significantly reduces freight costs.
Regolith (moon dust) can and will be used in 3D printing construction and from it, we also extract Helium3.
The use of naturally formed ancient lava tubes is a time saving idea for habitat construction, and protection from radiation.
We also have hydrogen fuel stored in the form of ice-water crystals in the craters on the dark side of the moon.
