Back in saturated air at sea level

The altitude sickness study conducted in the Valais Alps has delivered a sizeable yield: almost 1500 vials containing blood samples from the test subjects, frozen in dry ice at minus 80 degrees Celsius, were transported from the Margherita Hut at an altitude of 4554 metres back down to the DLR Institute of Aerospace Medicine in Cologne. There are also just under 200 urine samples, 44 saliva samples and 66 blood counts. read more

04:00, and outside Margherita Hut the world is pitch black. The clocks of the test subjects in the altitude sickness study sound their alarms. As the first group of mountaineers leave their lodgings for climbing tours in the Valais Alps, the study participants are already busy delivering the first set of data: headaches, quality of sleep, nausea, dizziness. All of these are noted in a daily journal, graded on a scale according to severity. read more

When bad news is good news

The participants all keep a diary, where they record their symptoms – which one would not want to have as they climb to their destination: the Regina Margherita Hut situated at an altitude of over 4500 metres. read more

Science, science management, science policy … part 3


Science needs flexibility if it is to produce innovation from creativity. At the same time, it is understandable that taxpayers demand sensible use of the funds they provide. Dispelling this apparent contradiction – individual 'liberty' versus societal expectations – is the primary task of those involved in the planning of research activities; that is, science managers. Political bodies have the task of formulating policy anywhere – but only there – where it can be defined on the basis of democratic legitimacy that is derived from elections. read more

Reflections on parting


On 16 May, the Space Shuttle Endeavour was launched en route to the International Space Station (ISS). On board was the large science experiment, AMS, designed to look for evidence of dark matter and antimatter. The flight is Endeavour's last, and it heralds the end of the shuttle era. In parallel with this somewhat technical farewell, we have also had to say goodbye to Thomas Reiter, who has been Director of Human Spaceflight and Operations for the European Space Agency (ESA)since mid-April. Two departures in the area of space exploration were sufficient reason for me to start reflecting on fundamental issues in spaceflight. read more

DLR, Europe and international cooperation


The topic of 'national activities versus international cooperation' has been discussed quite a bit recently. The 'either … or' question has become a fundamental issue for everyday politics. Our activities in the first two months of 2011 prove that we are not treating this as an 'either … or' issue; instead, we see the combination of national and European efforts and the activities arising from these efforts as a promising arrangement. read more

Wikileaks and the repercussions for DLR


The release of secret US documents has caused excitement in recent weeks, both in the news media and among the general public. The latest 'revelations' by Wikileaks concern DLR activities in the space field. Two things must happen now: the 'information' must be considered critically and the repercussions have to be thought about in detail. read more
