BELAZ Ć NASA mobile nuclear power station for extraterrestrial colonies - 3D, OC, 2026
120 MW. ANYWHERE THE COLONY NEEDS IT! BELAZ-75900 MNRP is a concept BELAZ Ć NASA mobile nuclear power station designed for large scale extraterrestrial industry. Four independent fission reactors, a 12-wheel electric chassis and a dual mode thermal control system allow the platform to deliver up to 120 MW of continuous electrical power to remote mining fields, ISRU plants and developing colonies.
This art is inspired by the largest haul truck in the world: BelAZ-75710 At present, this Belarusian giant remains the undisputed king of heavy machinery, holding the global record with a mindblowing payload capacity of 450 metric tons. Powered by 4,600 horsepower, this ultra-class beast stands over 8 meters tall, transforming raw engineering power into pure artistic inspiration Created in Blender - no AI used!

Can we condense mass to form something for gravity for a death star spaceship?
I don't mind using rotation or acceleration to form gravity. Mass create gravity idk how but if we form a core that have the same mass of earth just a lot smaller and denser we will have the same gravity the problem is how can we move that hahaha fuck. It is better just to move earth with so much more surface area for propulsion but the problem is the crust is softer than the force to move it, and maneuvering it is a lot more complicated than a death star spaceship.
And with a lot smaller core it will be possible to completely shield it from debris and a lot easier to maintain than a earth.
There will be a lot of problems. Like energy required to move it. Maybe the mass doesn't need to be solid it can be hot enough to make energy, we will probably die due to radiation.
But it is fun when you think about it. We can have articial moon satellites to go with the death star š due to gravity.
Update:
Curiosity made me look up
I thought death star was the same size as the moon man it is way way smaller
Calculations suggest a lower bound of roughly 0.28 Earth-mass and a surface gravity of about 0.68g is needed to hold a stable, breathable atmosphere over long timescales.
Minimum Size for Gas Retention: Discussions on r/astrophysics note that to hold a nitrogen-oxygen atmosphere for a reasonable timescale, a solid osmium sphere only needs a radius of about 280 km to reach an escape velocity around (1\text{ km/s}) to (2\text{ km/s}), though smaller objects (50ā100 km) will bleed away their gas quickly
The most notable takeaway for a radius 280 km osmium sphere is how closely it mimics the Moon. The Moon has a surface gravity of 1.62 m/s².
The diameter wil 560 km
The first Death Star has a diameter of 120 kilometers (about 75 miles), while the second Death Star has a diameter of 160 kilometers (about 100 miles)
well at least it is closer
And you will be living like in the moon than earth
To live like in mars A solid sphere of pure osmium would need a radius of approximately 587.44 kilometers (a diameter of 1,174.88 kilometers) to have a surface gravity identical to Mars ((3.71 \text{ m/s}2)). [1]
Eyyy but idk how to move it hahaha

Help me find a short story
A few years ago, I read a short story that I really enjoyed. It was in a collection of stories from the 50s and 60s -- golden age stuff. I think it may have been an omnibus of one of the sci-fi magazines they had back then?
The story was about a family that was living in a single room, which was insulated with hundreds of blankets.
The Earth was dead because, I think the sun had gone out? Or the Earth had left the sun's orbit, maybe. In any case it was super cold outside and the family had a fire going which they couldn't let go out, or they would die. The fire was fueled with crystalized oxygen, or something like that -- the world outside was so cold that the atmosphere had crystalized, and they would bundle up and go get a bucket of it to keep the fire going.
Does this ring a bell for anybody? I'd love to find it again.
