Two weeks on a quasi-7000er

Ralf Dujmovits (l.) and Nancy Hansen in the still empty DLR living area

This seven-thousander has neither a summit, nor does it offer impressive views. It covers an area of ​​only around 110 square meters – and is located on the grounds of the German Aerospace Center (DLR) in Cologne. A hypoxia chamber within DLR’s medical research lab “:envihab” – the name stands for environment and habitat – will be comfortably furnished in the coming months.

Four weeks in the chamber

In mid-May, Ralf Dujmovits, the only German mountaineer who has climbed all 14 eight-thousanders, and his partner, the Canadian climber Nancy Hansen, will move in there for four weeks. They are taking part in a highly interesting hypoxia study conducted by DLR in cooperation with the University of Texas. The assumption: Although extreme oxygen deficiency threatens life, there could also be a positive effect on the body.

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 ams@dlr.de 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?

Motorised glider over Everest

Flying high

Flying high

Science and adventure are often not far apart. With a motorised glider and a 3-D camera on board scientists of the German Aerospace Center (DLR) and pilots of the “Mountain Wave Project” have explored Mount Everest a week ago. “The conditions were ideal, despite the wind speeds at the summit of Everest, which neared 100 kilometres per hour,” said pilot Klaus Ohlmann. “The almost turbulence-free slope updrafts helped us ascend quickly.” Ohlmann and his co-pilot Jona Keimer started in Pokhara in the Annapurna region and needed one and a half hour to reach the highest mountain in the world. With the images of the special camera a precise 3-D model of the region around Mount Everest will be produced, in which, according to DLR, even small objects of only 15 centimeters size are visible. The model shall be useful for disaster protection and rescue operations. The video of the DLR awakens wanderlust. Check it out for yourself:
