NASA's Exobiology Program

Origins of Life, 1984
The goal of NASA's Exobiology Program is to understand the origin, evolution, and distribution of life, and life-related molecules, on Earth and throughout the universe. Emphasis is focused on determining how the rate and direction of these processes were affected by the chemical and physical environment of the evolving planet, as well as by planetary,

Extreme environments and exobiology

Giornale botanico italiano, 1993
Ecological research on extreme environments can be applied to exobiological problems such as the question of life on Mars. If life forms (fossil or extant) are found on Mars, their study will help to solve fundamental questions about the nature of life on Earth.

Exobiological Investigations on Russian Spacecrafts

Astrobiology, 2003
To 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, 1995
The 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 in Earth orbit

Origins of life and evolution of the biosphere, 1996
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 endeavor, scientists from a wide variety of disciplines are involved, such as astronomy, planetary research, organic chemistry, paleontology and the ...

Exobiology research on Space Station Freedom

Advances in Space Research, 1995
The 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

2001
In 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.
