Mars can become the main space base for future space missions to explore the entire Solar System and explore other stars, star systems and the Galaxy.
Elements that are in short supply on Earth can be delivered via future space missions.
The tasks of such spacecrafts will include sending signals and receiving any possible space signals and relaying these signals to Earth.

The space industry should serve for the benefit of humanity and contribute to the fulfillment of the highest tasks of humanity instead of launching useless satellites and clogging outer space.
