Some of the concerns during Mars 500, an experiment that will simulate a 500 day voyage to the planet Mars, are how the mock crew will handle the effects of isolation, boredom, and being confined solely to a very small spaceship like environment during the “journey”.
With up to 100 experiments to carry out during the [...]

Joey Parlett’s series of 36 sketches based on photos taken mainly during the Apollo Moon missions.

With some asteroids valued at over US$20 trillion, due to the quantities of precious metals that they are made up of, it is only a matter of time before the exploration of space becomes a commercial undertaking.
There are millions of asteroids of different sizes and composition flying throughout space. One category, known as S-type, [...]

An additional six methods, other than searching for radio signals, that may lead to the discovery of intelligent life beyond the solar system.
They are all in the long-shot category though, but some of the possible indications of alien life elsewhere in the universe make for interesting reading:
A civilisation could head off disaster by finding [...]

Travellers aboard a light-speed capable spacecraft would find themselves exposed to lethal levels of radiation – generated by the hydrogen atoms that drift through space – as their velocity approached the speed of light.
It is an experience one scientist describes as akin to standing in front of the beam created by the Large Hadron [...]

Among other things, your height can increase by five to eight centimetres as a result of an extended stay in a zero gravity environment, such as Earth orbit.

The end of the Apollo Moon program by no means heralded the end of space exploration, rather there’s been a change in the way we explore the solar system and the rest of the universe.
The truth is that we have made enormous progress since the 1960s – not in “conquering” space but in discovering [...]

Vincent Fournier’s “behind the scenes” gilmpses of parts of the US and Soviet space programs.

The over-exuberant optimism towards humanity’s future among the moons, planets, and stars, seen especially during the space-age, seems to have all but dried up in recent years.
Disappointingly, those golf trips to the moon turned out to be the final frontier. No galactic cruises, humanoid robots or self-aware artificial intelligence. No immortality, nuclear-powered vehicles or [...]

Space travel technology has brought about all sorts of innovations and improvements right here on Earth.
Many people do not realize that everything from toys to sunglasses and even horseshoes have benefitted from technologies originally intended for astronauts, shuttle flights, and other elements of space exploration. While some inventions stem directly from NASA and its [...]
