Human presence in outer space began with the first launches of artificial object in the mid 20th century, and has increased to the point where Earth is orbited by a vast number of artificial objects and the far reaches of the Solar System have been visited and explored by a range of space probes.

3. Residing in Earth's orbit removes the protections of the Ozone layer which absorbs harmful radiation emitted from the Sun. Living in orbit around Earth exposes humans to ten times more radiation than humans living on Earth. [52] These radiative effects can invoke symptoms such as skin cancer.
