   NASA's Artemis program has a goal of landing humans on the moon in 2025 to begin building a base camp. This long-term human presence on the lunar surface will help NASA prepare for human space exploration missions of greater distance and duration, including an eventual crewed flight to Mars. Space can help us prepare the feutre Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras.

Explanation:

There hope it helps Also you could've done a little bit of resheerch skimmed a cupple sights to get an idea on what to wright about then go from there  its just an idea thoe

We have learned more about gravity, the magnetosphere, the atmosphere, fluid dynamics, and the geological evolution of other planets, for instance, through studying the solar system. This sparked the creation of numerous technologies that benefit the economy and enhance life on Earth.

In 2025, astronauts will be sent to the moon as part of NASA's Artemis mission to begin creating a base camp. This prolonged human presence on the moon's surface will help NASA get ready for longer-duration human space flight missions, such a possible crewed trip to Mars.

Additionally, you could have done some research by scanning a few websites to get an idea of what to write about before moving on from there.

Therefore, We wouldn't have GPS, precise weather forecasting, solar cells, or ultraviolet filters in eyeglasses and cameras without space missions. We can prepare the feutre by using space. We can use space travel to support or refute scientific hypotheses that were formed on Earth.
