If you are a fan of science fiction, one of the standard scenarios is the crushing weight that astronauts face on launch: the terrible pressure of terrific g-forces, suddenly slamming the helpless astronauts into their couches and the terrible effort to move that this produces. This is part of the legend of space flight. In [...]
As the world faces arguably its greatest crisis since the Spanish ‘Flu of 1918-1920 and NASA gears up steadily for the first of its three, planned Artemis flights, which will take man (and almost certainly at least one woman) back to the Moon, there is a certain irony in the fact that Artemis 2, the [...]
Last week I passed an important milestone and, as one does these days, I sent a WhatsApp to the family group stating that I was starting my sixty-first orbit of the Sun. What I thought was a very simple statement, caused great puzzlement amongst its (non-scientist) readers and, after explaining it to them, they found [...]
If you are familiar with the night sky and have had some good weather recently, you may have noticed that something is wrong with the constellation of Orion. Normally, Betelgeuse, the bright, orange-red star, marking the left shoulder of the giant, is only a little fainter than Rigel, the blue-white star to the bottom-right of [...]
The Calendar, Father Christmas and the Three Kings Christmas is celebrated in many different ways around the world and at different times. The town of Bethlehem celebrates Christmas no fewer than three times: on December 25th, on January 6th and on January 19th. The reason for this is that the Church of the Nativity [...]
If the seemingly incessant autumnal – and now winter – storms abate for Christmas (and the weather forecast for Spain suggests that they might) you may get a chance to look up at the Christmas sky. If you do so as darkness falls, you will not be able to miss the brilliant, white “star”, low [...]
Who remembers Apollo 12? It should have been the flight that gave the American public a television spectacular that knocked spots off the short Apollo 11 moonwalk. The first moon landing was basically a PR exercise: the moonwalk was the shortest possible and science was almost an afterthought. The Apollo 11 landing was to give [...]
Recently, we have celebrated the 50th Anniversary of “One Small Step”. History records that Neil Armstrong was the First Man and that the first manned landing on the Moon was made by Armstrong and Aldrin. History also records that, had things been only slightly different, the first landing could have been made by Grissom and [...]
The Apollo 11 Landing: staring-down disaster The multiple issues that faced the Apollo 11 Moon landing are generally well known. Alarms, fuel, … so many things happened in such a short time that could have led to disaster, or to an abort. Much has been said about the coolness of Neil Armstrong under massive [...]
One of the articles of faith of the Apollo Moon landing is that the items left on the lunar surface will last, if not for all time, at least for millions of years. We can see the tracks left by the astronauts of each of the Moon landings. The disturbed earth – more accurately, disturbed [...]
