How did the Apollo flight computers get men to the moon and back ?

Admin computers, Science, space 2 Comments

There is much speculation by some, as to how the flight computer aboard the Apollo missions managed to get men to the moon when it had just a tiny fraction of the computing power of something like a modern smartphone. But this is quite misleading as there was not one solitary computer controlling the Apollo craft, there were 4 computers and no fancy touch screens, GUI’s or other things in a typical computer of today to waste resources on. The first of the 4 computers was the Saturn Launch Vehicle Digital Computer or LVDC, this got the rocket from the …

For all of the celebrations surrounding the first manned lunar landing of Apollo 11 in 1969, what is forgotten today is just how close they and the other Apollo missions flew to the edge of disaster. Apollo 11 came within seconds of aborting the landing because they had over shot the landing area and were running low on fuel. This was only one of several issues with the Apollo missions that arose that could have led to the loss of the mission and crew, though as it turned out only Apollo 13 came close to this happening. This excludes the …

What would happen, if one day you woke up and time no longer existed?,  I’m not talking about stopping time or what we may think is the definition of time. I mean no time, no flow from past to present to future, no entropy, just now. No clocks or calendars, no hours, minutes, seconds, days, years, millennia, aeons just … now. In this little thought experiment, let’s assume that time has existed up until you woke up and then ceased to exist anywhere in the universe. Now, everything in your life, all your memories of your past and what is …

Why is the sun hot?,  now before you jump on the comments and say “because it’s the sun, stupid” think about it, our sun is basically a giant nuclear reactor at the centre of our solar system but not like the ones on earth. They create energy by nuclear fission, that is they split large atoms like uranium into smaller lighter ones and in the process it releases large amount of energy. Atomic bombs also work in the same way which is why they are so destructive. The sun creates its energy by nuclear fusion, the most efficient way to …

Why cant you fly a plane into space?

Why can’t we fly a plane into space ?

  Why can’t we fly a plane into space, what stops it from just flying higher and higher until we are in space? Well, there a several issues but assuming we are in something like a normal jet airliner, then one of the main problems is the air or lack of it as we get closer to space. A plane flies because as it is propelled forward, the wings, which are shaped to make the air flow faster over the top of them than the bottom, generate lift. As the plane goes faster the wings creates more lift and when the …
