Displayed are configurations of aliena class thrusters contained in gyroscopic spheres
attached to a submarine with a skeleton and modified into a PNN spaceship for Mars.

Some thrusters, which develop more than 10,000 tons of thrust in 1 hour, are located under the solar panels that power the storage batteries. Water tanks will then be attached to the skeleton
to shield it from any type of radiation.
Both the aliena thrusters and the solar panels are attached to the skeleton.
Without some very high quality dilithium crystals it will never work ;-)

Grok works well to a PNN spaceship toward Mars

That's an intriguing concept render of a propellantless
propulsion spaceship designed for Mars missions! The design features
a central cylindrical body with a symmetrical array of eight spherical thrusters
(likely housing electromagnetic components), solar panels for power, and a lattice frameworkrCovery sci-fi, almost like a high-tech octopus ready to propel itself without traditional rockets.
This appears to be the ALIENA prototype from ASPS (Associazione Sviluppo Propulsione Spaziale),
promoting their PNN (Propulsione Non Newtoniana) system. They claim it's an electromagnetic thruster
that generates thrust without expelling mass, allegedly violating Newton's third law in a controlled way
via electrodynamics (e.g., Lorentz forces), allowing spacecraft to accelerate continuously at
constant
power and reach Mars in days rather than months.It's a bold idea in the realm of reactionless drives,
similar to the old EmDrive hype but with their own twistrCoASPS has been testing prototypes for decades,
reporting gradual thrust buildup in lab setups (like pendulum tests). However,
mainstream physics remains deeply skeptical: conservation of momentum is a cornerstone,
and no independently verified propellantless drive has overcome that yet (EmDrive was eventually debunked
as measurement error). Recent 2025 discussions on propellantless concepts focus more on proven tech like
solar sails or magnetic sails, not these.If this PNN truly works as claimed, it would revolutionize getting
to MarsrCono more massive fuel tanks, endless acceleration, reusable ships arriving "whole."
Elon and SpaceX are betting on chemical rockets + refueling for now, but
breakthroughs like this
could change everything.
Cool sharerCogot any more details or updates from ASPS?
