Famous picture of Andrée's balloon wreck https://gamesandtehories.blogspot.com/ Kimmo Huosionmaa Another very well known polar expedition was made by Salomon Andrée or S.A Andrée (1854-1897)  in 1897, and that trip was fatal for him and his two mates. The expedition seems very interesting because when Andrée left for his final journey, he used the hydrogen balloon, what was made of rubber. That means the balloon couldn't be fixed if something made the hole on it. And because the balloon was made of rubber, the refilling with hot air was impossible. There is the fatal design error in that balloon. If the air sailor wanted to use hydrogen balloon, should the rubber balloon put in the canvas balloon, what would make the trip safer. The problem with hydrogen balloon is, that it can raise very high, and be trimming the altitude must the hydrogen released from rubber balloon. And in the case of Andrée, this gas must be replaced by something. If the hydrogen balloon wou...

Artist's impression of the balloon, that investigates the surface of Titan (Picture 1) Kimmo Huosionma How some animal actually moves its legs might seem not very interesting or relevant knowledge. But this information is the most relevant, when we are creating walking robots, what can move them in extreme difficult landscape. Those next-generation robots can be actually similar than some space probes in 1960’ and 1970’s. They would have similar legs than those landing crafts, what landed on Moon and Mars. But they would have one big difference, those legs would be moving. The next generation space probe would travel across the landscape like some giant spider, and that allows to investigate larger areas than before. The problem with the wheeled bed is problematic, because the wheels need quite a flat base, that they could be used. And if the site of that robot or craft would be on the edge of the sand, the waves would be problematic, because the wheels have so big la...
