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…
Has lurid fiction like the movie Iron Sky any basis in fact? Everyone knows that WW2 Germany developed rockets far in advance of the Allies, but some argue that in 1945 the Third Reich was on the verge of developing a space program! Ever since Adolf Hitler’s ‘Thousand Year’ Read more…
NASA’s Space Shuttles have become a familar sight in their thirty years of service, but there have been other shuttle designs which never left the ground.Some were ingenious alternative concepts to the vehicle which is shortly to be retired, some were potential replacements and there was even a couple of Read more…
One day vast solar sails pushed along by rays of sunlight may carry payloads between the planets. Tracy McConnell explains how this romantic vision is slowly becoming a fact.

It is 14 November 2019 and the 50th anniversary of the Apollo 11 mission, when humans first walked on another world, has been and gone but today a new and exciting voyage begins. A massive booster stage pushes a spacecraft out of Earth orbit. This vehicle comprises two Orion 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…
The late ’50s and ’60s were a different time from the anxious era that is today. Nuclear power and space travel were both cool and wonderful new technologies. The only thing that could be cooler and more wonderful would be to combine the two. One suggestion was the US Read more…
