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

Admin computers, Science, space 0 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 …

What if Apollo had crashed on the Moon ?

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 …

Why is the Sun hot ?

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 …

Apollo, the Lunar Dust and NASA's Dirty Problem

Apollo, the Lunar Dust and NASA’s Dirty Problem

Admin space, Technology 0 Comments

Sometimes the smallest things can be one of the biggest headaches. During the Apollo missions of 1969 to 72,  the tiny particles of lunar dust turned out to be a major issue. Described as being as fine as talc but as rough as sandpaper, it also has properties that make it dangerous for both men and machines and has been cited as a bigger problem for future astronauts than radiation by some scientists. The lunar surface is covered in a thin layer of dust which has been created by the bombardment of meteorites and micrometeorites over millions of years. These …

How did Apollo deal with the Van Allen radiation belts ?

How did Apollo deal with the Van Allen radiation belts ?

Admin space, Technology 0 Comments

One of the most hotly contested procedures during the Apollo missions was the how NASA dealt with the issue of the Van Allen belts, the naturally occurring belts of radiation that surround the earth, both on the journey to the moon and returning from it. To some this just proves the point that NASA never went to the moon because they contest that if the crew went through the Van Allen belts they would have received a lethal dose of radiation and died during or shortly afterwards but as we know that didn’t happen, so how did they achieve this. …
