Imagine taking two human beings and sealing them in a box for 500 days. The pair must survive on only the boxes of food and water crammed around them. Throughout their confinement they are at risk of being sprayed with a lethal dose of radiation. This is not the cruel Read more…
As we further consider spacesuits we may find a question arising in many of our minds: Why build any new spacesuits at all? Why not just reuse previous designs, especially when the expense of space technology manufacture is considered? The answer is that with man’s space exploration program being in Read more…
Spacecraft with a lenticular design (that is, shaped like a biconvex lens) were actively studied by NASA and US industry in the late 1950s and early ‘60s. A craft of such a shape would experience lower heating on re-entry than a winged layout as the heat would be spread over Read more…

NASA’s next manned spacecraft will be the Orion, a capsule which will be carried into space by a rocket. Weighing 25 tonnes, each Orion will carry up to six people. Accommodation on board is cosy at best, cramped at worst. Orion was intended to take astronauts to the Moon and Read more…
In the early 1960s, the sky had no limits for NASA . Planners for the agency foresaw an ever-expanding future of exploration through the Solar System. Some amazing missions were planned. Alas in August 1967, the US Congress refused to support NASA’s plans for the 1970s. Ever since then NASA’s Read more…
“Rods from God” is the nick-name given to a hypothetical orbital weapon for bombarding targets on the Earth from space. Just how feasible is this concept? There are undeniable links between the spaceflight and military communities but apart from a few tests of anti-satellite weapons, the odd armed space Read more…
