Suitability by celestial body
The Moon — The "Beginner Level"
Why it works so well: Low gravity and virtually no atmosphere.
The advantage: The mobile anchor needs no aerodynamic design. It hovers as a pure propulsion module and can lift cargo precisely off the ground without frictional heating or wind resistance. The load on the tethers is minimal.
Use: Ideal for exporting helium-3 or lunar ores.
Mars — "Home Turf"
Why it works so well: Gravity is low, and the atmosphere is so thin that it offers hardly any resistance, yet still provides enough pressure for simple aerodynamic stabilisation.
The advantage: The raw materials (Deimos cores) are available right on site. The areostationary orbit is lower than Earth's geostationary orbit, which shortens the required tether length.
Use: The backbone of Mars colonisation, enabling the mass transport of 10,000-tonne modules.
Earth — The Benchmark
On Earth, we are up against two giants: strong gravity and a dense atmosphere. Here, the SpaZeLift has to go "full throttle" — the SpaZeLift anchor must withstand glowing plasma shields. A technological extreme scenario.
Mercury — The "Powerhouse"
Why it works so well: Gravity similar to that of Mars, and virtually no atmosphere.
The advantage: Its close proximity to the Sun provides abundant energy for tether winches and engines. The SpaZeLift could be powered almost entirely by solar energy here.
Use: Mining heavy metals and serving as an interplanetary energy hub.
Venus — Extremely Difficult

Jupiter — The "Final Boss"
Gravity is 2.5 times stronger than on Earth. A SpaZeLift here would need graphene tethers of unrealistic thickness and engines of unimaginable power.
Suitability: Extremely low — practically impossible (energy requirements too high, the tether would snap).
Saturn — Gas Harvesting
Gravity here is surprisingly moderate (close to Earth's gravity). A SpaZeLift could "fish" in the gas layers to extract valuable gases such as helium-3 or methane.
Suitability: Medium to good as an atmospheric scoop — perfect for "gas scooping", but the distances are enormous.
Uranus & Neptune
As with Saturn, gravity here is surprisingly moderate (close to Earth's gravity). Here too, a SpaZeLift could extract valuable substances such as helium-3 or methane from the gas layers.
Suitability: Extremely difficult due to the great distance from Earth, but technically comparable to Saturn.
Pluto — A Supply Station at the Edge of the Solar System
At the edge of the Solar System, the SpaZeLift would be the perfect supply station for deep-space missions. The extremely low gravity turns lifting 10,000-tonne loads into an almost effortless task with minimal energy consumption.
Large Icy Moons — Ganymede, Titan & Europa
These are the real "gold mines" of the system.
- Titan (moon of Saturn): A paradise for the double-delta anchor. Titan has a dense atmosphere but very low gravity (similar to the Moon).
- Ganymede & Europa: As on Mercury or the Moon, there is virtually no atmosphere here. The SpaZeLift can operate directly above the ice shells to deploy drilling modules and extract water and ice for interplanetary propellant needs.
Rating: Excellent.
Dwarf Planets & the Asteroid Belt — Ceres & Co.
Ceres (asteroid belt): Since Ceres has very little gravity, the SpaZeLift would need hardly any engine thrust. It would serve as the central logistics hub for the entire asteroid belt — here, the SpaZeLift acts more like a "tow truck".
