What is time?

Here, we are in front of the most perplexing philosophical question of all time. But what does that "of all time" actually mean? Do we suggest that something was happening back there in the past, which is done right now and we can only remember it? Or that it is still present somehow, not only in our minds but in the mysterious interwoven tissue of space-time? Or it is just an expression? Well, one thing is for sure, on that topic we can't really lean on science for a decisive answer. In fact, it is the scientific discourse that brought even more confusion or we can say perspectives to the question. There are many theories and most of them seem to be equally plausible. So what are your personal feeling about it? Do you believe that there is only the present moment or maybe you are eternalist?

For thousands of years, mankind has been gazing at the sky, wondering and creating theories about what is there. In 1610, Galileo started the era of scientific exploration of space with the first telescopic observations of the night sky. 300 years later, on June 20, 1944, the V-2 rocket for the first time passed the Karman line (the border between earth atmosphere and space) and marked the first official space flight. On February 20, 1947, the first animals - fruit flies, were launched into space. And so, step by step, we reached the moment, when the first man-made object is going to take off, hover, and land back on the surface of Mars. Let's see what is all the fuss about...

Chinese Lunar Exploration Program

The Chinese Lunar Exploration program has the brave goal to bring astronauts to the moon in the 2030s and eventually to build an outpost near the lunar south pole. The program includes 4 phases: 1. Reaching lunar orbit - already done by Change'1 in 2007 and Chang'e 2 in 2010. 2. Unmanned landing and driving on the moon surface - done by Chang'e 3 in 2013 and Chang'e 4 in 2019. 3. Collecting samples and sending them to the Earth - this is the task of the current Chang'e 5 and the future Change'6 missions. 4. Building a robotic research station near the Moon's south pole.
