On Saturday I got two postcards: one from the USA and one from Austria.
The card from the USA is an official card and shows Mars. Mars is the fourth planet from the Sun, Earth's neighbour and the second-smallest planet in the Solar System. It is a terrestrial planet with a thin atmosphere. As such it has been subject of many explorations from the USA, the Soviet Union, the European Space Agency, India and soon China. The idea of life on the Mars however is much older. Famous early examples of stories about Martian life include H. G. Wells' War of the Worlds and Kurd Lasswitz' Two Planets. Also from the 19th century comes the idea of Martian Canals, but there have also stories about Martian journeys in the 18th century.
The two stamps issued on 19th July 2019 to celebrate the 50th anniversary of the Moon Landing were used on the card. I wonder, when will the first humans be on Mars?
Thank You very much Pam!
