SO ENDS this second week on the extraordinary Russian ISS finding of intact microorganisms outside the space station. Whether by Earth updraft, which they suggest is unlikely, or by origin in space, the result is the finding of life in outer space, and opens the door to the question of duration and boundaries for such creatures. As it is probable that multicellular life began from these kinds of microorganisms, their presence in space is a game changer of enormous proportions. View in LinkedIn

INTACT LICHEN PHOTOSYNTHESIS. “In addition, when photosynthesis was specifically studied, activity was demonstrated post-exposure with high viability of algal cells and low rates of impairment. However, a strong impairment of both photosynthesis and photoprotective mechanisms was observed when isolated alga were irradiated emphasizing the importance of the protection afforded within the lichen symbiosis resulting from morphological adaptation, the presence of lichen compounds, and the ability of lichens to survive desiccation.” https://lnkd.in/dnvYcSS View in LinkedIn

LONG TERM LICHEN SURVIVAL. “Lichens in space are exposed to the combined effects of insolation, UV irradiation, cosmic radiation, extremely low temperatures, and a vacuum. Hence, after long-term exposure of 559 days to these conditions, Xanthoria elegans (Link) Th. Fr. showed considerable resistance with post-exposure activity 50–80% that of previous values in the alga and 60–90% in the fungus. Growth and proliferation of isolated algal cells were also demonstrated after exposure.” https://lnkd.in/dnvYcSS View in LinkedIn

THE QUESTION. “The presence of DNA of wild land and marine bacterial genera on the ISS indicates their possible transfer from the stratosphere into the ionosphere with the ascending branch of the global electric circuit, alternatively to their entry into the Earth’s environs from space.” https://lnkd.in/dNHWs6R View in LinkedIn

BEASTIES DETECTED. “We detected the DNA of bacteria of the genus Mycobacteria and extreme bacteria of the genus Delftia (family Comamonadaceae, order Burkholderiales) in the samples of cosmic dust. It was shown that the DNA sequence of one of the bacteria of the genus Mycobacteria was genetically similar to that previously observed in the sea surface microlayer at the Barents and Kara seas’ coastal zones.” https://lnkd.in/dNHWs6R View in LinkedIn

INNER MAGNETOSPHERE. “The quasi-dipolar inner magnetosphere extending roughly out to geostationary distance has a variable field structure caused by the competing effects of the internal dipole field, magnetotail current sheet, dayside magnetopause currents, and the ring current within the region itself.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAGNETOSPHERE. “The structure and dynamics of the current sheet in the magnetotail control the energy storage and release processes initiated with the enhanced dayside reconnection at the magnetopause. The high-speed plasma flows, strong particle energization processes, and rapid reconfiguration all are major parts in creating the space weather effects in the inner magnetosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
