Will space junk end our modern way of life ? – The Kessler Syndrome

In Aerospace, Rockets, Science, space, Videos, Weapons by Paul Shillito3 Comments

Space aint what it used to be, mainly because just like here on the earth, we are slowly filling the most important part just above us, with junk. After sixty years of space travel, flight debris, or space junk, has accumulated around the Earth, to the point that it’s becoming dangerous. With the amount of junk in orbit expected to triple within the next fifteen years, experts are beginning to take the problem very seriously indeed. Because if they don’t, a theory known as the Kessler Syndrome suggests that the space around Earth could soon become so clogged up with …

What Happened on the Moon Before Apollo ?

In Rockets, space, Technology, Videos by Paul Shillito2 Comments

The Apollo landings from 1969 to 1972 marked a high point in lunar exploration but Apollo didn’t just rock up on to the moon out of the blue, it took many, many missions by probes and landers over the preceding years to establish if we could send men to the moon and get them back. It’s quite strange to think that even by the late 1950’s, just over 10 years before Neil Armstrong set foot on the lunar surface we knew surprisingly little about the moon other than what we could observe from the earth and the hypotheses we drew from …

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

In computers, Science, space, Videos by Paul Shillito2 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 ?

In accidents, Science, space, Videos by Paul Shillito2 Comments

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 …

Apollo, the Lunar Dust and NASA’s Dirty Problem

In space, Technology, Videos by Paul ShillitoLeave a Comment

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 …

Why can’t we see the Apollo lunar landers from Earth ?

In cameras, space, Technology, Videos by Paul Shillito1 Comment

When you look up at a full moon, just remember that somewhere on the lunar face, the remains of Apollo 11, 12, 14, 15, 16 and 17 along with 8 unmanned Russian Luna missions and 5 pre-Apollo unmanned American surveyor missions are all still there….. silently looking back….. unless of course you’re a NASA non-believer. so… why can’t we see these from the earth, why can’t we train our best telescopes on to the moon’s surface and see them there exactly where we left them the best part of 50 years ago. Well, there a bit of a problem…. and …
