    Results/More Information

    Planetary protection is one of the key problems of deep space exploration. Risks of the possible transfer of biological material across interplanetary space are being assessed during space exploration. The Biorisk investigation examines the impact of the space environment on a variety of bacteria, fungi, plant seeds and dormant organisms.

     

    Initial results from the second (April 2007 – July 2008) Biorisk study indicated that bacterial and fungal spores in the resting stages and evolutionary advanced organisms in the dormant stages were capable of surviving the environment of space (Baranov 2009).

    According to Novikova 2011, an 18 month study demonstrated that bacterial and fungal spores could survive the harsh effects of outer space. Also, following 13-month and 18-month exposures to the space environment, seeds of higher plants remained viable and were able to germinate and produce plants which did not differ from ground controls in their genetic, biochemical, physiological and morphological characteristics. Dehydrated dormant larvae of lower crustaceans were capable of surviving the extremes of the space environment. 

     

    One of the many seeds tested in Biorisk was barley. On Earth, seeds are stored with climate control prior to planting to ensure a successful germination. For the Biorisk investigation the seeds were stored without climate control and exposed to the harsh environment of space. Eighty-two percent of the barley seeds within Biorisk were successfully germinated upon return to Earth. These seeds exhibited normal growth, ripening, and reproduction of several generations. Biorisk results demonstrated that barley seeds can be preserved in the space environment without phenotypic (observable traits) and genotypic (cellular traits) changes for at least one year with healthy and vigorous growth, guaranteeing a safe supply of food in space (Sugimoto 2011).
