Space exploration is the use of astronomy and space technology to explore outer space. [1] While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one ...
Space travel can refer to: Spaceflight, flying into or through outer space. Spacefaring, to be capable of and active in space travel. Human spaceflight, space travel with a crew or passengers. Interplanetary spaceflight, travel between planets. Interstellar travel, travel between stars or planetary systems.
Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the ...
Spaceflight. Space tourism is human space travel for recreational purposes. [1] There are several different types of space tourism, including orbital, suborbital and lunar space tourism. Tourists are motivated by the possibility of viewing Earth from space, feeling weightlessness, experiencing extremely high speed and something unusual, and ...
This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space . This timeline generally does not distinguish achievements by a specific country or private company, as it considers humanity as a whole. See otherwise the timeline of private spaceflight or ...
The future of space exploration involves both telescopic and physical explorations of space by robotic spacecraft and human spaceflight. Near-term physical exploration missions, focused on obtaining new information about the Solar System, are planned and announced by both national and private organisations. Tentative plans for crewed orbital ...
Intergalactic travel is the hypothetical crewed or uncrewed travel between galaxies. Due to the enormous distances between the Milky Way and even its closest neighbors —tens of thousands to millions of light-years —any such venture would be far more technologically and financially demanding than even interstellar travel .
t. e. Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth, each of whom published works proposing rockets as the means for spaceflight. [a] The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun.
