Exobiological Investigations on Russian Spacecrafts
Astrobiology, 2003To investigate the possibility of prebiotic synthesis of organic molecules in open space, conditions involved irradiating nucleosides and inorganic phosphate during five Earth-orbiting Russian space missions that included Salut-7 (13- and 16-month missions), Mir, Bion-11, and Cosmos-2044.

Site selection for Mars exobiology
Advances in Space Research, 1995The selection of sites on Mars that have a high priority for exobiological research is fundamental for planning future exploration. The most immediate need is to identify targets for high resolution orbital imaging during the Mars Observer and Mars '94/'96 missions that can be used to refine site priorities for surface exploration.

Exobiology research on Space Station Freedom
Advances in Space Research, 1995The Gas-Grain Simulation Facility (GGSF) is a multidisciplinary experiment laboratory being developed by NASA at Ames Research Center for delivery to Space Station Freedom in 1998. This facility will employ the low-gravity environment of the Space Station to enable aerosol experiments of much longer duration than is possible in any ground-based ...

Ultraviolet Radiation and Exobiology
2001In comparison to the Earth, extraterrestrial environments possess quite different UV radiation regimes, both in terms of absolute flux and in terms of spectral quality (Horneck et al. 1984; Horneck 1993). For example, the moon has no atmosphere and thus its UV regimen is determined solely by the extraterrestrial spectrum.

Exobiological experiments in Earth orbit
Advances in Space Research, 1998Abstract The primary goal of exobiological research is to reach a better understanding of the processes leading to the origin, evolution and distribution of life on Earth or elsewhere in the universe. In this endeavour, scientists from a wide variety of disciplines are involved, such as astronomy, planetary research, organic chemistry, palaeontology ...

Accretion models of the Saturnian satellite suggest that heating released during late stages of its formation was sufficient to create a warm, dense atmosphere with mass at least 30 times greater then the present value (Lunine and Stevemson, 1983) and large open ocean on its surface.

Processing of organic molecules by liquid water was probably an essential requirement towards the emergence of terrestrial primitive life. According to Oparin's hypothesis, organic building blocks required for early life were produced from simple organic molecules formed in a primitive reducing atmosphere.
