Astrum Propellantless Propulsion, Lab Testing:

Testing is conducted in a certified vibration-isolated room. The propulsion system is placed on a highly sensitive scale and produces downward-directed thrust, which results in a measurable increase in the system’s apparent weight.
The prototype generates approximately 50 mN of constant thrust, which is sufficient to reach most planets in the solar system in under a year.

It is important to highlight two key points:
1. The scale starts at zero and returns to zero once the propulsion drive cools down, indicating that the system’s mass remains unchanged.
2. The entire drive rests on a single metal ball to ensure that the observed effects are not influenced by uneven weight distribution. 

Astrum Propellantless Propulsion, Field Testing:

In this experiment, we use helium balloons to reduce the weight of the propulsion system to just a few grams, as the system produces thrust in the same range. This setup allows us to visually observe how the system operates.

Next, we drop the system from a height of 50 centimeters. You can compare the drop times with the system turned off (in the first test) and with it turned on (the next three experiments). The shorter drop times when the system is active clearly indicate the presence of additional downward force generated by the propulsion system.
