Wedge pillow in the backpack?

Olympus Mons, giant mountain on Mars

Compared to the highest peak on Mars, Mount Everest is a dwarf. Olympus Mons rises 26 kilometers above the surface of the red planet. However, this is not the reason why the German Aerospace Center (DLR) deals with high altitude sickness. For a – as I find, very interesting – study, the DLR is looking for mountaineers, who will ascent in the period from 7 to 20 August after a night on the Gnifetti Hut (at 3,647 meters) to the Margherita Hut. The “Capanna Regina Margherita” is located on the summit of the Signalkuppe in the Valais Alps and is, at 4,554 meters, the highest building in Europe. The DLR scientists want to find out whether it helps against high altitude sickness if climbers are sleeping with a raised upper body. The test persons will use wedge pillows, which ensure that they are raised by 30 degrees. In intensive care units in hospitals such pillows have been used successfully for a long time.

Mountaineers who want to participate in the study at the Regina Margherita mountain hut in August can either register by email at or register at the valley station in Alagna or the Gnifetti Hut with the DLR study supervisors. I have talked to Dr. Ulrich Limper who heads the study. The 35-year-old doctor has been working at the DLR for three years.

Dr. Limper, why is an aerospace center interested in the health problems of mountaineers? Are there similarities between astronauts and climbers?

Mountain bikers and runners needed for study on Kibo


According to the statistics, Kilimanjaro is one of the top mountain destinations in the world. Every year tens of thousands of people tackle the highest mountain in Africa. In 2016, reportedly, more than 30,000 visitors have reached the highest point at 5,895 meters. The “Kibo” is said to be a trekking mountain, several easy routes lead to the summit. Only during the rainy seasons in April/May and October/November the tourist flow decreases a bit. Many operators offer hikes to the roof of Africa as a week trip – this short stay also ensures that the mountain is so popular. However, it is less known that every year several hundred tourists suffering seriously from high altitude sickness have to be rescued from Kilimanjaro, and about two dozens of them die, in some years even significantly more.
