Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth , but also includes space probes for flights beyond Earth orbit.
The following outline is provided as an overview of and topical guide to space exploration. Space exploration – use of astronomy and space technology to explore outer space. [1] Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft.

The Space Exploration Portal Space exploration is the endeavor of humans to use technology to reach, explore, and exploit the space outside the Earth 's atmosphere. It is generally based on the use of rockets to transport machines, animals, and humans to space.
A fictional astronaut must be presented as living in the period of the early exploration of space, i.e. from the beginning of the Space Age to the present, and for a few decades into the future; currently, in the period of about 1960–2060.
Fictional explorers, characters known for exploration, the act of searching for the purpose of discovery of information or resources, especially in the context of geography or space, rather than research and development.
MONS – (telescope) Measuring Oscillations in Nearby Stars, a Danish space telescope that was proposed and designed but not built [6] MOST – (telescope) Microvariability and Oscillations of STars, a space telescope designed to detect oscillations in the atmospheres of stars and extrasolar planetss in orbit around other stars
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
