Space exploration
Ever since Neil Armstrong became the first man to walk on the Moon, space exploration has captivated the minds of both the scientific world and the general public. To this day there have been hundreds of manned space flights from all around the globe and even more probes sent to explore our Solar System. With the dawn of private space flight through companies such as SpaceX and the continued desire to find another inhabitable planet, the incentive to probe the edges of the Solar System only grows.
