As has been shown in the previous chapters, biotechnology research in space has led to significant scientific breakthroughs and technological developments with great application potential. This is true for protein crystallization: here, significant progress in structure determination of certain molecules could be achieved with the help of improved crystals grown in space thereby supporting drug discovery and design. It is also true for certain aspects of cell biology; here, not only the basic un...

Already early protein crystallization experiments in space indicated that more extended crystallization periods, beyond the flight durations of shuttle missions or unmanned orbiters, will be beneficial for the majority of microgravity protein crystal growth experiments. Beside preceding intensive efforts to adjust and optimize crystallization conditions to meet the microgravity time span of orbiters flight duration, video imaging of some experiments showed that the crystallization process was no...

Gravity, a physical factor being available and constant on Earth since its origin some three and a half billion years ago, has governed the origin, the distribution and evolution of life and still does so. To fully understand its importance, experiments under space conditions, i.e. in the absence of gravity, have been performed since the advent of spaceflight in the middle of the last century. Projects in biotechnology and cell biology are in the focus of this booklet. Due to the lack of gravity...

The utilization of microgravity for improving protein crystallization and thereby structure determination started in the early 1980s onboard of TEXUS sounding rockets and of the US Space Shuttle. After the successful pioneering work by Prof. Littke, especially the German space life sciences program put much effort into this topic. In spite of some technical and methodological drawbacks, early successes could be obtained as well. In some cases, microgravity experiments enabled crystallization of ...

Abstract The challenges confronting health care especially in today’s ageing societies of the industrialised countries demand a paradigm change in the medical sector. Among experts, it is generally expected that medicine and health care will focus on three tasks in the future: – health maintenance in healthy people, – individualised health care, and – challenging the traditional relation between physician and patient by providing the doctor’s advice irrespective of the location of the patients (...

Was haben Astronauten und Kosmonauten mit alteren Menschen auf der Erde gemeinsam? In der Schwerelosigkeit des Weltraums lauft im Zeitraffer dasselbe ab, was Menschen beim Alterungsprozess auf der Erde erleben: Muskelabbau, Osteoporose, Ruckenbeschwerden, Kreislauf- und Orientierungsprobleme, zunehmende Kraftlosigkeit sowie Probleme im Immunsystem. Daher konnen in der Raumfahrtmedizin an gesunden Astronauten irdische Krankheiten und Alterungsphanomene studiert werden; die Funktionen vieler Syste...

Am 31. Oktober 2011 um 22:58 Uhr (MEZ) startete das chinesische Raumschiff Shenzhou-8 vom Weltraumbahnhof Jiuquan in der Inneren Mongolei in den Weltraum. Mit an Bord war die in Deutschland entwickelte und gebaute SIMBOX-Experimentapparatur mit insgesamt 17 chinesischen, deutschen und gemeinsamen Forschungsprojekten aus der Biomedizin. Diese Mission war in mehrerer Hinsicht ein Meilenstein: Zum ersten Mal kooperierte China im Shenzhou-Programm – dem Kernstuck der bemannten chinesischen Raumfahrt...
