And suddenly the call came from space: “Here is Alex”. At first Ralf Dujmovits did not know who was talking at the other end of the telephone line: “Alex? Then I suddenly recognized the voice I had heard two days earlier during the broadcast of the rocket launch.” Alexander Gerst inquired from the International Space Station (ISS) about the condition of the German climber and his Canadian partner Nancy Hansen in the hypoxia chamber of the German Aerospace Center (DLR) in Cologne. “It sounded like he was sitting next door.” For a quarter of an hour, Ralf, the first and so far only German climber to have scaled all 14 eight-thousanders, spoke to “Astro Alex”, the first German astronaut to take command of the ISS. “He was very interested in our experience in the lab. That was great.” Of course, Nancy talked to Gerst too. For both climbers it was a “real highlight”, says the 49-year-old Canadian.

Bottled oxygen on a mountain has always been out of the question for me. On principle. Today I made an exception – for a “virtual mountain”. To be able to visit Ralf Dujmovits, the only German mountaineer who has scaled all 14 eight-thousanders, and his partner, the Canadian climber Nancy Hansen, it is mandatory to use a breathing mask. After two weeks in the hypoxia chamber of the German Aerospace Center (DLR) in Cologne, the two test persons have reached the simulated target altitude of 7,112 meters. The percentage of oxygen in the air, normally 21 percent, was gradually reduced to eight percent by adding nitrogen. “It’s like climbing a mountain. The acclimatization is almost done, now we’re heading for the summit,” says Ralf. “The time on the summit will be of course much longer.”

The Japanese climber Nobukazu Kuriki has been found dead today on Mount Everest. The 35-year-old had reported yesterday from Camp 3 at 7,400 meters via Facebook. It was hard, said Kuriki, assuring he would be careful. This morning, his team informed that Nobukazu was in bad shape and that he was descending. Later, he did not respond to radio calls. His camera crew climbed up and found Kuriki lifeless near Camp 2.

The doors have closed behind Ralf Dujmovits and Nancy Hansen. The so far only German climber who has scaled all 14 eight-thousanders and his Canadian partner moved in a 110-square-meter hypoxia chamber of the German Aerospace Center (DLR) in Cologne on Tuesday. As reported, the two mountaineers are participating in a study conducted by DLR in cooperation with the University of Texas to investigate whether extreme hypoxia can also have a positive side effect for human beings. US researchers from Texas found in two experiments with mice that heart muscle cells devided when the animals were exposed for two weeks to oxygen deficiency corresponding to conditions at 7,000 m. In mice which had previously been triggered myocardial infarctions, cardiac function improved after two weeks of hypoxia.
Medical control around the clock
Ralf and Nancy, both healthy, are the subjects of the pilot study. They are to stay in the hypoxia chamber for about a month. In the first few weeks, acclimatization as on a Himalayan expedition is simulated. The oxygen percentage in the air will be gradually lowered and temporarily increased only twice in between – as if the two climbers would descend again to breathe thicker air. The last two weeks, the 56-year-old German and the 49-year-old Canadian are to spend in a simulated height of 7,000 meters. The experiment can be stopped at any time in case serious problems arise. A DLR research team monitors Dujmovits’ and Hansen’s state of health around the clock. The daily schedule includes heart and lung function checks, blood and urine tests, fitness checks and so-called “cognition tests”, which check the reaction and perception of the subjects.
Yesterday, I visited the two climbers in their new “home”. That was possible on Wednesday for the last time without breathing mask. After more than half hour in a simulated altitude of about 3,700 meters, I felt a little bit dizzy. I preferred to do the interview with Ralf subsequently in thick air, by phone.
Ralf, you can not get out, there is no daylight, and the oxygen is lowered. That does not sound like a holiday apartment.

A joint week in Nepal is behind Ralf Dujmovits and me. As reported before, we inaugurated the first two parts of the new school building in Thulosirubari, a small mountain village about 70 kilometers east of Kathmandu, which could be built thanks to our aid project “School up!”. And we laid the foundation for the second construction phase. In Kathmandu I conducted some interviews – you could already read those with the expedition operators Arnold Coster and Mingma Gyalje Sherpa, more will follow shortly. Ralf took the time to meet old acquaintances and to visit some of his favorite spots in the capital. The 56-year-old is so far the only German mountaineer who has scaled all 14 eight-thousanders. Only on Mount Everest in fall 1992 he used bottled oxygen. Later he tried seven times to climb the highest mountain in the world without breathing mask, seven times he failed to reach the summit – most recently in spring 2017 at 8,580 meters on the Tibetan north side of the mountain.
Ralf, we are now here in Kathmandu, not far from Mount Everest, about 160 kilometers as the crow flies. Is it not itching you a bit?
Not at all, at the moment. I have completed this story for me. Of course, I follow what’s happening on Everest. This is still very exciting. But for myself, I have closed the chapter Everest.

This roadblock is not an ordinary one. Five hundred meters in front of the school grounds in Thulosirubari, 70 kilometers east of the Nepalese capital Kathmandu, our journey in a jeep ends. Eight musicians stand in the middle of the dusty piste through the village. When Ralf Dujmovits – the first and so far only German mountaineer who scaled all 14 eight-thousanders – and I get out of the car, they begin to play for us on their traditional instruments. Behind the music playing village band we ascend the last meters to the school.
There a big event has been organized for us. Several hundred students, parents, teachers, local notables and other residents of Thulosirubari are awaiting us for the ceremonial inauguration and handing over of the first two parts of the building to the local school committee – made possible by your donations to our aid project “School up!”. The old school had been so badly damaged by the devastating earthquake in Nepal on 25 April 2015 that it had had to be demolished. At the end of June 2015, I had launched together with Ralf Dujmovits and the Austrian climber Gerlinde Kaltenbrunner “School up!” to rebuild the Thulosirubari school as soon as possible.

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.

The finishing line of the first stage of our aid project “School up!” is in sight: The first two buildings of the new school in the Nepalese mountain village of Thulosirubari will most probably be ready for occupation before the beginning of winter. The doors are fitted these days, Shyam Pandit, liaison man of the German aid organization “Nepalhilfe Beilngries” in the Himalayan state, writes to me. The windows are already installed. Subsequently, only the painting is missing. By the end of the month, says Shyam, the contractor wants to hand over the two first building units. Then the construction work will go on.

I will sleep well, no matter how loud it is. “I have to warn you,” said the hotel staff at the front desk. “We have three wedding parties today, and music might be played until 6 a.m.” The hotel in the village of Altrip, located on the so-called “Blue Lagoon” about 15 kilometers from the gates of Ludwigshafen, specializes in the align of weddings. On the other hand, it also offers a special discount for bike tourists. Exemplary! And so I stood around 6 p.m. in my bike pants in the hotel lobby, a few meters away from me one of the three brides – and many guests who were dressed up. “Don’t worry,” I answered to the receptionist. “I’m all run down, I’ll sleep like a stone.”

It was the day of encounters. At first I cycled – for a change, in sunshine – along with a Swiss from the town of Zug, in his mid-60s, tanned, on a mountain bike that had already seen better days. “I’ve stopped working after 45 years,” the cyclist told me. “And now I am fulfilling my life dream. I always wanted to make a long bike trip.” I asked him how much time he took for the ride along the Rhine. “I’ll see how far I get until winter,” he said, grinning. In the further conversation it turned out that he was also a passionate mountaineer. He had climbed all four-thousanders of his home country, said the Swiss: “Actually, I had always dreamed of climbing Mount Everest one day. But tourism on this mountain has nothing to do with the way of climbing that I like.”

It is undisputed that Adrian Ballinger reached the summit of Mount Everest without bottled oxygen last Saturday. But a debate rose about how he did it. The trigger was my article about a conversation with Ralf Dujmovits on Monday, two days after his failed attempt without breathing mask on the north side of Everest at an altitude of 8,580 meters. During the satellite phone call, the 55-year-old German climber had accused Ballinger that the American had reported about his ascent in real time via the social networks, but had not mentioned some facts. On the descent, for example, Adrian had been led by an Ecuadorian mountain guide on the short rope, said Ralf. Ballinger’s team responded promptly.

Tired and disappointed. That’s not only the way Ralf Dujmovits feels, he also sounds like this. The 55-year-old climber from Germany talks quietly and slowly, when he tells me via satellite phone about his failed summit attempt on Everest without bottled oxygen. On Saturday, Ralf had turned around at an altitude of 8,580 meters, just before the Second Step, the most striking rock step on the Northeast Ridge: “That was bitter.”

Mount Everest has shown his teeth again on the past weekend – just on the day when eight climbers were on their summit push without bottled oxygen. Contrary to expectations, on Saturday wind gusts and snowfall in the summit area made the ascent difficult. The result: two summit successes without breathing mask on the north side, one on the south side. Two climbers, who used supplemental oxygen at all and reached the highest point at 8,850 meters. And three summit aspirants, who turned back because of concerns for their health.

What a pity! Ralf Dujmovits has not been able to fulfill his dream of reaching the summit of Mount Everest without bottled oxygen. The 55-year-old turned back at an altitude of 8,500 meters. From Camp 3 at 8,300 meters, he telephoned his life partner, the Canadian climber Nancy Hansen. “He had to turn back at 8,500 m because a storm blew in: 40 kph winds with snow. He was losing feeling in his hands and feet,” Nancy wrote on Facebook. “As you can imagine, he is extremely disappointed. The weather just didn’t allow for a summit.” Ralf’s wise decision demands respect and shows that he was still in control of himself.

Ralf Dujmovits is close to his big goal. In his eighth attempt, the 55-year-old finally wants to scale Mount Everest without bottled oxygen. Ralf is only about eight hours of ascent away from the highest point on earth at 8,850 meters – if everything goes well. Today Dujmovits, according to his life partner Nancy Hansen, reached Camp 3 on the Tibetan normal route at 8,300 meters, from where he called her by satellite phone. There had been a thunderstorm for the last hour, Ralf told the Canadian. It had taken him five hours to climb the 600 vertical meters from Camp 2. “He feels a little tired, but he sounds very alert and normal,” Nancy wrote on Facebook. “He will drink a lot now, rest a few hours, and leave for the summit at 1am Nepali time (1.15 pm Friday in Canada, 9.15 pm Friday in Germany).”
