"Space exploration, like its classical form astronomy, is one of the main sources for space science."
"It was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality."
"The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s."
"The Opel-RAK program and the spectacular public demonstrations of ground and air vehicles drew large crowds, as well as caused global public excitement... and had a large long-lasting impact on later spaceflight pioneers like Wernher von Braun."
"Common rationales for exploring space include advancing scientific research, national prestige, uniting different nations, ensuring the future survival of humanity, and developing military and strategic advantages against other countries."
"The early era of space exploration was driven by a 'Space Race' between the Soviet Union and the United States."
"In fact, the reason NASA was made was due to the response of Sputnik I."
"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 are often taken as landmarks for this initial period."
"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."
"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)."
"Constellation, a Bush administration program for a return to the Moon by 2020 was judged inadequately funded and unrealistic by an expert review panel reporting in 2009."
"The Obama administration proposed a revision of Constellation in 2010 to focus on the development of the capability for crewed missions beyond low Earth orbit (LEO), envisioning extending the operation of the ISS beyond 2020, transferring the development of launch vehicles for human crews from NASA to the private sector, and developing technology to enable missions to beyond LEO."
"In the 2000s, China initiated a successful crewed spaceflight program."
"India launched Chandraayan 1."
"China, Russia, and Japan have advocated crewed missions to the Moon during the 21st century."
"The European Union has advocated crewed missions to both the Moon and Mars during the 20th and 21st century."
"Studying space exploration can help us understand the advancements in technology, the race for space supremacy, and the milestones achieved in human spaceflight."
"The development of large and relatively efficient rockets during the mid-twentieth century allowed physical space exploration to become a reality."
"Focusing on cooperation, as demonstrated with the International Space Station (ISS), allows for shared resources, knowledge exchange, and joint scientific endeavors."
