Space exploration：Wikipedia

**Space exploration** is the physical investigation of outer space by uncrewed robotic space probes and through human spaceflight. Landmarks of this era include the launch of the first human-made object to orbit Earth, the Soviet Union’s Sputnik 1, on 4 October 1957, and the first Moon landing by the American Apollo 11 mission on 20 July 1969. The Soviet space program achieved many of the first milestones, including the first living being in orbit in 1957, the first human spaceflight (Yuri Gagarin aboard *Vostok 1*) in 1961, the first spacewalk (by Alexei Leonov) on 18 March 1965, the first automatic landing on another celestial body in 1966, and the launch of the first space station (*Salyut 1*) in 1971. A string of discoveries in the Solar System (and beyond) followed, then and in the next centuries: the mountains of the Moon, the phases of Venus, the main satellites of Jupiter and Saturn, the rings of Saturn, many comets, the asteroids, the new planets Uranus and Neptune, and many more satellites.

Human Exploration: From Earth to Space. # space exploration. **space exploration**, investigation, by means of crewed and uncrewed spacecraft, of the reaches of the universe beyond Earth’s atmosphere and the use of the information so gained to increase knowledge of the cosmos and benefit humanity. Achieving spaceflight enabled humans to begin to explore the solar system and the rest of the universe, to understand the many objects and phenomena that are better observed from a space perspective, and to use for human benefit the resources and attributes of the space environment.

2. Why Should We Explore Space? What Are the Benefits for Us?

# Why Should We Explore Space? why should we explore space. ## Space Exploration Advances Scientific Understanding. At the core of our pursuit for space exploration lies humanity’s thirst for knowledge. Space exploration plays a huge role in expanding our understanding of the universe – from studying planets to learning the mysteries of black holes, dark matter, dark energy, and other groundbreaking subjects. ## Space Exploration Is a Catalyst for Developing Technology and Economic Prosperity. ## The Economic Promise of Space Exploration. But the economic advantages of space exploration go beyond mere technological advancements. ## Space Exploration Serves Human Survival Interests. ## Exploring Space Fosters Societal Values That Will Benefit Humanity. Degree programs focused on space studies like the ones provided by American Public University (APU) are useful for students seeking a greater understanding of space exploration. Ultimately, our space studies programs equip individuals with knowledge, practical skills, and a multidisciplinary mindset, enabling them to contribute to the continuous exploration of our expansive universe.

3. Explore – Space Exploration – Background Information

While our current human exploration is through the International Space Station and transportation to and from it, future activities could include missions to the Moon, Mars, and other locations in the Solar System. These require rockets to launch from the Earth or Moon or a space station, landing capsules, and some type of facilities or colony from which to explore the Moon and Mars. Space capsules are the compartments designed to support astronauts during their journey through space, and land people or instruments on the surface of Earth or another planet. Space stations are platforms for long-term living and working in space that orbit Earth; in the future, they may orbit other planets or moons. Space stations can carry out scientific research in an environment not found on Earth; they allow scientists and engineers to test materials and designs for future space travel. Space colonies on the Moon, Mars, asteroids, other worlds and in orbit around the Earth have been suggested, designed and promoted since the 1950’s.
