CENTURIES SURVIVAL POTENTIAL. “In the experiment EXPOSURE-E maximum dose rates reached 0.4 mGy per day. With this dose load and the median lethal dose for bacterial forms from hundreds of Gy, the object transported from the Earth’s surface into outer space has the potential to remain intact to radiation exposure for hundreds of years.” https://lnkd.in/dNHWs6R View in LinkedIn

PURE MAGNETISM. “As the IMF turns southward, dayside reconnection changes the conditions at the magnetospheric boundaries and begins to increase the open flux content in the magnetotail. In order to maintain pressure balance between the plasma sheet plasma pressure and the lobe magnetic pressure, the cross-tail current intensifies and the plasma sheet is compressed.” (IMF= interplanetary magnetic field). https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

NEEDING EXPLANATION. “The bacteria survival during the transfer from the Earth’s surface to the ionosphere is a particular problem. Intact DNA of the genera Delftia and Mycobacteria detected in this paper may indirectly indicate the intactness of the whole cell; otherwise the formation of thymine dimers would make the PCR conducting impossible. However, this issue needs further explorations.” 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
