Many people dream about making a journey into space sometime, or setting foot on a celestial body. And despite the fascinating images and movie footages we are able to enjoy here on Earth, the wish remains to experience this sight for ourselves. The German scientist and astronaut Ulrich Walter, recently related that the view onto the Earth in weightlessness and the realization not to be the centre, would change the individual thinking in a profound way. »Up there« in space, he was always happy.

Are we alone in the universe? Are there other intelligent forms of life in space or are we alone? These questions have been on mankind’s mind, since we consciously reflect our existence and raise our gaze toward the starlit sky.
With the beginning of space travel, there arose the idea, of sending messages to potential extraterrestrial life. The question, which information is suitable, a representative picture of the entire human race and their lives on planet Earth, is particularly exciting.
Buzz Aldrin (* 1930) is an American astronaut and the man, who, as part of the Apollo 11 mission on 21st July 1969, stepped onto the Moon as the second person, just after Neil Armstrong. He stood in the shadow of his colleague and one could assume that he may have suffered under these circumstances. But this was not the case, he did not really want to be in the spotlight and was satisfied coming second. After he set his feet into the dust 20 minutes after Armstrong did, he said: »Beautiful, beautiful. Magnificent desolation.«
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.
The Christmas advertising campaigns of the well known English department store John Lewis, have developed into a yearly tradition since their start in 2007 and have become part of pre-Christmas Internet culture. John Lewis has been awarded the “IPA Effectiveness Award” with its 2012 Christmas campaign. This year, the video called “Man On The Moon” was published – parallel to the Christmas full moon on 25th December 2015.
When inviscid lava flows out of the volcano, it is possible that cavities are created inside the conduits, due to the different speeds of flow and temperatures. It is like a roof being formed above the flow of lava, which continues to flow inside. After cooling of the rocks, tubular cavities remain.
This phenomenon exists on Earth when volcanoes erupt, and scientists assume that those tubes and cavities could also be prevalent on the Moon, dating from a time when vulcanoes were still active there. The lesser gravity benefited the formation of the tubes and might have also contributed to the fact that there could be kilometer-sized cavities underneath the Moon’s surface.
Luna 2 was a Soviet space probe that impacted the Moon on 13th/14th September 1959. Space probes are unmanned flying objects that are used for exploration. In this case, it was about exploring the Moon, with the goal to fly a human to the Moon and have them return safely. History shows that this did not become possible until ten years later, with the moon landing of Neil Armstrong within the framework of the Apollo 11 mission, in July 1969.
There are currently precisely six American flags on the Moon, which were left behind by the respective astronauts at the moon landings of the Apollo missions 11,12,14,15,16, and 17. The flag of the Apollo 11 mission led the way. On 21st July 1969 at 03:56 am (CET), Neil Armstrong was the first human to set foot onto our Moon and spoke the legendary sentence: »That’s one small step for (a) man … one … giant leap for mankind«. Together with his colleague Buzz Aldrin, he then planted the first flag on the Moon, which was apparently not so easy, due to the space suits, the pole rods and the condition of the ground.
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).
