What is Space Exploration?

Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Space Exploration. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.

Check that you can explain Space Exploration in your own words and give one example from everyday life. If you can do that, you have understood the core idea.

Understanding Space Exploration helps you explain the environment around you and weigh up how people can protect it.

Space Exploration in detail

Space exploration began with Sputnik (1957), the first satellite, followed by Yuri Gagarin as the first human in space (1961) and the Apollo 11 Moon landing in 1969. Since then, probes such as Voyager have visited the outer planets, rovers have explored Mars, and space stations such as the ISS host international research.

Telescopes, including Hubble and the James Webb Space Telescope, look deep into the Universe. Space exploration has advanced technology and knowledge, with spin-offs such as satellite navigation and medical devices. It is costly and risky, and raises questions about space debris and priorities. Future goals include returning to the Moon, crewed Mars missions and searching for life.
