Space exploration involves the investigation of outer space through manned and unmanned missions. Since the launch of the first artificial satellite, Sputnik, in 1957, humanity has made significant strides in understanding the universe. Landmarks include the Apollo moon landings, Mars rover missions, and the deployment of space telescopes like Hubble. Space exploration has contributed to advancements in technology, such as satellite communication and GPS. However, challenges like high costs, space debris, and potential risks to astronauts remain. As interest in exploring Mars and beyond grows, international collaboration will be key to addressing these challenges.
