The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens.

[1] [2] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. [3] Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
For this reason, fossil collectors commonly break open concretions in their search for fossil animal and plant specimens. [9] Some of the most unusual concretion nuclei are World War II military shells, bombs, and shrapnel, which are found inside siderite concretions found in an English coastal salt marsh. [10]
The Space Station Biological Research Program is the main project concerning life sciences research to be conducted on the International Space Station. [1] It is a program of NASA's Ames Research Center, with co-operation from other national space agencies. The SSBRP's goal is to study the development, life cycle, and behavior of certain ...
The light-absorbing compound in the fungus cell membranes had the effect of turning the water black. [5] While there are many cases of extremophiles (organisms that can live in severe conditions such as that of the radioactive power plant), a hypothetical radiotrophic fungus would grow because of the radiation, rather than in spite of it. [6]
A model for investigating mechanisms of heart disease and mechanisms of activation of sympathoadrenal activity in humans during spaceflight (CARD) [7] A description of the experiment and the performance status is given in ESA's Erasmus Experiment Archive (EEA) and in addition a condensed account of the experiment's aim and foundation has been provided in ESA's Human Spaceflight Science ...
Astro microbiology, or exo microbiology, is the study of microorganisms in outer space. It stems from an interdisciplinary approach, which incorporates both microbiology and astrobiology . Astrobiology's efforts are aimed at understanding the origins of life and the search for life other than on Earth.
