This fourth volume in the series, dedicated entirely to the results
of the first European study of the effects of long-term confinement
and isolation. The volume continues to attempt to fulfill the aim
of this series, to bring the findings and accomplishments in the
field of space biology and medicine to a wider group of scientists
than merely the relatively small group of biologists and
physiologists currently involved in space experimentation.
The contributions are not only nicely spread geographically with
three chapters from the United States, two each from Russia,
Europe, and Japan, they also offer a wide range of topics in the
field, covering humans, animals, plants, cells, and even potential
extraterrestrial beings.
As before, not only problems investigated and results obtained are
reviewed, but also some of the technical aspects peculiar to this
field are treated. An example in this volume is the chapter on
virtual environments by Ellis, which is meant to help investigators
understand the opportunities that these techniques might offer for
future investigations.
In view of the limitations on flight opportunities and the
constraints still inherent in orbital experimentation, it is also
important to consider the information that can be obtained from
studies on the ground. In addition to simulation studies like bed
rest for human subjects (see the chapter by Edgerton et al. on
neuromuscular adaptation), tail suspension of rats, and plants on a
clinostat (see the chapter by Masuda et al.), there is the
interesting possibility of using gravitropic mutants for studying
the effects of weightlessness on plant growth as described by
Takahashi and Suge.
Two chapters are devoted to a review of the results on rats flown
on nine Cosmos biosatellite flights between 1973 and 1989: the
chapter by Krasnow deals with the neuromorphological effects of
micro- and hypergravity; that by Popova and Grigoriev with the
metabolic effects of spaceflight. The effects of weightlessness on
heart and lung function in humans are reviewed in detail by
Bonde-Petersen and Linnarson.
While the study of humans, animals, and plants in spaceflight have
taught us much about the effects of the space environment on living
organisms, we still have a very limited understanding of the
mechanisms operating in these effects. The chapter by Rijken et al.
on the effects of gravity on the cellular response to epidermal
growth factor demonstrates how, by a judicious use of experiments
on the ground and in sounding rockets, the mechanism of a
microgravity effect on cell growth could be unravelled.
The question whether there is intelligent life elsewhere in the
universe has intrigued mankind for a long time. In the chapter by
Coulter et al. on NASA's High Resolution Microwave Survey the
project to search for the existence of such life is described. The
postscript to this chapter tells how through an unfortunate
decision of the U.S. Congress this project after a successful start
is threatened with an untimely ending.
