Space exploration is the ongoing discovery and exploration of celestial structures in outer space by means of continuously evolving and growing space technology.While the study of space is carried out mainly by astronomers with telescopes, the physical exploration of space is conducted both by unmanned robotic probes and human spaceflight.While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the early 20th century that allowed physical space exploration to become a reality.
O’Neill asked an advanced group of students to study a direct question: “Is the surface of a planet really the right place for an expanding technological civilization?
” The “O’Neill colonies” that he designed in response to this question, first with his students, and later with teams of architects, planners, engineers, and artists, were huge cylinders, spheres, and toruses with new surfaces for new kinds of civilizations inside.
The renderings produced for O’Neill’s 1970s project were painted by Rick Guidice, who trained as an architect and graphic artist, and Don Davis, who had a background illustrating planetary science.
Both men had roots in the counterculture, and they filled their space-habitat interiors with Buckminster Fuller’s domes and Reyner Banham’s architectural megastructures.
In the 2000s, the People’s Republic of China initiated a successful manned spaceflight program, while the European Union, Japan, and India have also planned future manned space missions.

China, Russia, Japan, and India have advocated manned missions to the Moon during the 21st century, while the European Union has advocated manned missions to both the Moon and Mars during the 21st century.It was a turbulent time: Cultural change had seemed to slow down, and people were newly aware that resources on Earth were shrinking, while pollution and environmental destruction were growing.If our horizons didn’t expand, the man warned, they might end up limited forever.From the 1990s onwards, private interests began promoting space tourism and then private space exploration of the Moon (see Google Lunar X Prize).An artist's rendering of a space habitat that Jeff Bezos presented onstage for Blue Origin.O’Neill’s book about this work, Jeff Bezos was one of Gerard O’Neill’s students at Princeton in the mid-1980s.By then, cultural interest, and NASA funding, for O’Neill’s ideas had peaked.Meanwhile, the appetite for large-scale public expenditures had soured.Now, in 2019, Jeff Bezos wants his private space company to take over the public imagination about life in space.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 Aleksei 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.After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station (ISS).
