The TV camera’s Apollo left on the Moon

This is the Apollo 17 Lunar Module, and the moment when Gene Cernan and Harrison Schmitt, the last men to stand on the Moon’s surface left to return to earth… but if no one else is there, who’s operating the camera as it pans up and follows the ascent module? The view is actually from a video camera mounted on the Lunar Rover, which remains on the moon to this day. Remotely operated by ground control via the large high gain antenna on the rover itself, the shot was meticulously planned, and timed to account for the 1.2-second delay in …

Secret Soviet Lunar Rovers and Extra Terrestrial Cars

Secret Soviet Lunar Rovers and Extra Terrestrial Cars

Admin Aerospace, Extraterrestrial, space, Technology, Travel 0 Comments

For the last 50 years or so we have been using wheeled robots and vehicles to explore other worlds from secret Soviet lunar rovers to the first lunar car to the latest Mars Rovers, we owe a lot to our extra-terrestrial wheeled helpers. NASA recently released new concept art for ‘the Mars 2020 rover’. The robotic lab is shown in action in its potential landing sites on Mars: currently, three locations are being considered, and a final decision will be made in 2018 or 2019. If the images look like something you’ve seen before, it’s because the new rover is the …

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 …

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 …
