For the unique environment of Loshen Star, rockets and spacecraft are, to some extent, the same thing.
One is for single use, while the other can be reused and has more functions. But in terms of thrusters, don't they all burn methane and oxygen to generate high-temperature, high-pressure gases that are expelled to obtain power?
If the maneuverability of spacecraft improves, the performance of rockets will naturally also improve.
Things like before, sending a probe to Earth requiring a rocket with a mass of 70,000 tons, will never happen again.
Given this, launching probes to every larger planet to comprehensively investigate their resource reserves and prepare for the future became inevitable.
Although the human world back then had already conducted thorough investigations of every large celestial body, Tom did not have access to that data.
He still had to rely on himself.
