The medium-format cameras by the Swedish manufacturer Hasselblad, enjoy a legendary reputation and were – at least back then – probably the best cameras in the world. Not surprising that NASA chose exactly this brand during their equipment selection for their Moon missions. At that time, everything revolved around photographic quality of taking the pictures and moreso, around the reliability of the cameras. Back then, you did not have the opportunity to immediately examine whether a photograph turned out well, because all material could be developed only after the return to Earth. So, with regards to cameras there was the need to hedge one’s bets – inconceivable, if those photos would have turned out a complete flop.
When examining it thoroughly, we humans will never be able to touch the Moon directly, because even when an astronaut is standing on its surface, there is always the glove of the spacesuit in between, without which, life could not exist on foreign celestial bodies (consider also Mars).
There are a variety of dangers that the spacesuit protects the wearer from: vacuum, cold and heat, weightlessness, micrometeorites and radiation. Hereby, a distinction is made between suits that are only worn inside the space capsule during specific maneuvers, and suits that are used for space walks and actually leave the spacecraft.
After USA and the Soviet Union, China will be the third nation in the world travelling to the Moon with their space program, and they will probably land there with the astronauts as well in the long term. At the moment, an unmanned spaceship »Chang’e-3« (moon fairy) is on its way to the Moon since 1st December 2013, planning to land in the Mare Ibrium on 14th December and supposed to transport a rover for research purposes of the Moon’s surface. The vehicle is called »Yutu« (jade rabbit).
A 3D Printer is a device with which you can print three-dimensional objects. This may initially sound strange, but will become obvious once you know that the objects can be built in layers. The printer applies the relevant materials instead of ink (i.e. plastic) and consequently forms the result.
Because these printers are now available for consumers at normal prices, in the future, we will purchase merely printing data instead of the product. So this trend actually moves away from mass-market productions and towards individualized items.
