Explain present day use of technology, space exploration, and future programs that contribute to understanding earth and hazards from space

Present day technology has advanced remarkably in the 21st century. Advances such as the Higgs Boson, space exploration to Mars, pictures from far away galaxies thanks to the Hubble telescope. Multi-lateral collaborations between NASA (America), ESA (European Union), RFSA (Russia) and others in building and sustaining the International Space Station (ISS)where several tests, observations, experiments have been done in understand outer space and to detect threats such as large asteroids, atmospheric phenomena, weather patterns, etc. Innovation in space technology has made possible to send robots to Mars and map the area, take samples of soil which has made possible to consider the idea of sending a mission to Mars if necessary to check if it's sustainable for humans to live on Mars in case Earth's collapse in the future.
