How does a space probe like Voyager 2, which was launched in 1977, visit the 4 outer planets and travel over 17 billion kilometres over 40 years with almost next to nothing in the way of fuel. By the time Voyager 2 had reached Neptune, it had swung by Jupiter, Saturn and Uranus, travelled 7 billion kilometres and was still within 100km of it’s target and all with mid 1970’s technology. In the movies space craft just seem to fly to where ever they want and get there in no time at all but in our version of reality its …

How Did NASA Lose a Mars Space Probe Because of Maths?

For all the knowledge of the thousands of scientists and engineers in the space industry, sometimes the old adage “The best-laid plans of mice and men” can equally be applied to their efforts. This was certainly the case on the Mars Climate Orbiter mission of 1999 and this would go down in space history as one of the biggest facepalms to date. If you’re an avid comment reader, you may have seen comments on my videos about why I tend to use both Imperial and metric units, instead of just metric and the simple answer is that many people in …

Space Station Collision - Mir Crash with Progress Supply Vessel

Space Station Collision – Mir Crash with Progress Supply Vessel

Admin Uncategorised 0 Comments

Of all the 100’s of thousands of pieces of space junk and nearly 1500 satellites in orbit around the earth, it may come as a surprise that so far there has been only one major collision involving a manned craft and it affected both Russians and Americans. After the Apollo Moon landings, the US switched it long-term goal to the Space Shuttle system and the Soviet Union shifted its focus to a permanent working presence in space. During the 1970s, the Soviet design bureau OKB-1 developed the first manned space stations called Salyut. As the Salyuts came to the end …

Robonauts or Men - Which Will Step Foot on Mars First ?

Robonauts or Men – Which Will Step Foot on Mars First ?

Admin Aerospace, computers, robotics, space, Technology 1 Comment

Mars will probably be the next giant leap for mankind – but it’s not certain that the feet that step onto it will belong to a man or woman. The development of the robonaut, humanoid robots to go to Mars in our place, is well underway. Some experts say they’re cheaper, safer and more effective than sending humans to the red planet. So will a living, breathing person ever set foot on Mars? It was difficult enough getting to the moon, 239,000 miles, or 385,000 kilometres away from Earth. That’s nothing, compared to the 34 million mile, or 55 million …

Was the Space Shuttle Doomed From the Beginning

Was the space shuttle program doomed from the beginning ?

Admin space, Technology 1 Comment

When the space shuttle was announced in 1972 it was seen as the space vehicle to make low earth orbit space travel and living in space an everyday reality. But in hindsight many now believe that it was a failed project that was hamstrung by lack of funding and interest by government and sky high expectations from NASA that led them to sideline safety to ensure scheduled launches continued on time in order to secure future funding. Instead of expanding man’s horizons, it in fact limited them and stopped the development more effective, safer forms of both manned and unmanned …
