FURTHER WORK NEEDED. “Of course, this phenomenon needs further exploration, perhaps sequencing of other genes of bacteria from this genus. However, we can state that the upward transport of bacterial DNA is one explanation of the close similarity.” https://lnkd.in/dNHWs6R View in LinkedIn

VERIFIED LOWER UPWARD CURRENT. “Aerosol transport, including living organisms, from the Earth’s surface to the troposphere is well described. The examples of bacterial genera, which can be attributed to the aerobes of troposphere, indicating the transport mechanisms from the surface of the ocean and land, are presented in the third line of Table 2.” https://lnkd.in/dNHWs6R View in LinkedIn

BEYOND THE UPWARD CURRENT. “Transport from the troposphere to the stratosphere is also well described. It should be stressed that the transfer of dispersed particles from the troposphere to the stratosphere is possible not only during/via catastrophic events (volcanic eruptions, forest fires), but also during the passage of vortex areas where the troposphere dramatically changes its height.” https://lnkd.in/dNHWs6R View in LinkedIn

UNKNOWN BIOSPHERE BOUNDARY. “The result of this transfer is a steady presence of a microbial community in the stratosphere (Table 2, line 2), thus raising the question of the upper boundary of the biosphere.” https://lnkd.in/dNHWs6R View in LinkedIn

UPWARD MECHANISM HYPOTHESIS. “Transfer from the stratosphere to the ionosphere might be possible with the ascending branch of the global electrical circuit due to a variety of coupled mechanisms of turbulent electrothermodiffusion accompanied by mass transfer of dispersible material although these processes need further exploration.” https://lnkd.in/dNHWs6R View in LinkedIn

THE OPTIONS. “It is clear that there are different possible ways of dust transport to (and from) ISS not excluding the possibility of interstellar or interplanetary panspermia (Figure 5).” https://lnkd.in/dNHWs6R View in LinkedIn

THE OPTIONS DIAGRAM. “Figure 5. Possible ways of intact DNA (bacterial forms) transfer to the orbit of the ISS and from ISS surface. Kinetic constants of different transfer pathways of microorganisms are indicated as follows: hypothetic Arrhenius’ way from the interplanetary space: possible mass transfer of the dispersed matter from the Earth surface to the ISS orbit with the ascending branch of the global electric circuit: possible contamination way from ISS internal volume to ISS surface, and : dissipation of the dust from the ISS surface to space.” https://lnkd.in/dNHWs6R View in LinkedIn

POSSIBILITY. “The presence of the DNA of wild terrestrial and marine species of bacteria on the surface of the ISS indicates their possible transfer from the stratosphere to the ionosphere with the ascending branch of the global electric circuit although the details of the process have not been worked out.” https://lnkd.in/dNHWs6R View in LinkedIn
