Mass influx obtained from LLLTV observations of faint meteors

Since the advent of low light level television (LLLTV) systems, it has been recognized that such devices offer the ability to observe meteors as faint as 10th magnitude which allows the extension of optical meteor data to masses as small as 0.0001 grams. The Space Sciences Lab at Marshall Space Flight Center has been actively engaged in such observations using image orthicons and intensified SEC vidicons. The results of these observations are presented along with an interpretation in terms of mass-flux. This interpretation includes the development of a relationship between peak luminosity of a meteor and mass, velocity, and zenith angle that was derived from single body meteor theory and compares favorably with results obtained from the Artificial Program. Also included in the mass flux interpretation is an analysis of the observation response of a LLLTV system to fixed and moving point sources.

Review of NASA activities in materials sciences in space

In the year since the 18th Plenary Meeting of COSPAR, NASA has conducted eight materials processing experiments on the Apollo-Soyuz mission and 17 on two rocket flights. In addition, these three missions have implemented one Soviet and three German experiments. The Apollo-Soyuz results have confirmed and extended the findings of the Skylab experiments on solidification and crystal growth effects and have also established capabilities for separating living cells by electrophoresis and returning them still living to earth. The rocket missions provide repetitive flight opportunities much as the Space Shuttle will do, and they are being used to develop research approaches in which investigators will undertake projects calling for multiple space experiments rather than proposing experiments individually. During the year, NASA has also completed definition work on the major payload facilities planned for its initial materials processing experiment program on the Space Shuttle and Spacelab missions of 1980-81.

Life sciences and space research XXI(1); Proceedings of the Topical Meeting, Graz, Austria, June 25-July 7, 1984

Space research in biology is presented with emphasis on flight experiment results and radiation risks. Topics discussed include microorganisms and biomolecules in the space-environment experiment ES 029 on Spacelab-1, the preliminary characterization of persisting circadian rhythms during space flight; plant growth, development, and embryogenesis during the Salyut-7 flight, and the influence of space-flight factors on viability and mutability of plants. Consideration is also given to radiation-risk estimation and its application to human beings in space, the radiation situation in space and its modification by the geomagnetic field and shielding, the quantitative interpretation of cellular heavy-ion action, and the effects of heavy-ion radiation on the brain vascular system and embryonic development.

NASA's life sciences and space radiation biology

Plans for the various missions in which men and women are expected to participate during the next 10 years are outlined. Such missions include flights of up to three months duration in low earth orbit as well as possible short excursions to geosynchronous orbit. Research activities are described which cover the full spectrum of physiological and psychological responses to space flight. These activities are shown to contribute to the ongoing Shuttle program and the future Space Station. The paper includes a summary of the major technical thrusts needed to support extended habitation in space.
