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 [...]

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.

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

While some aspects of space travel as presented in science fiction movies and books are clearly implausible, others are plain inaccurate:
It’s hard to say whether it’s due to some misguided acting or a poor understanding of physics, but astronauts are often depicted moving in slow-motion when they’re in zero gravity. It’s probably because anytime [...]

I’m a space cowboy. I’ve made the Earth-Alderaan run a million times yet I’ve never managed to photograph the moment of transition from warp drive to conventional, impulse, drive. Today was my lucky day. Outta sight!

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 [...]

A summary of the how the two Voyager space probes have expanded our knowledge of the solar system’s outer planets.
How then to summarise Voyager? As Stone observes “I felt that we were all in the tradition of Galileo. He was the first to see the moons of Jupiter and the first to apply an instrument [...]

Photos from the Soviet/Russian “Buran” space program, that was abandoned in the mid-1990s. An unfortunate outcome given the amount of time, effort, and money that must have been invested in it.

Some people are questioning the value of the Mars-500 project, where six volunteers will be sealed – for 520 days – inside a spaceship-like chamber, as part of an experiment to understand the effects of deep-space travel on astronauts.
Some feel the simulation lacks much of the authenticity of an actual flight to the red [...]
