Zimmerman en Space

Het onderwerp is weleens vaker langsgekomen in deze podcast: de neiging van levende wezens om zelfs onder de meest bizarre omstandigheden te persisteren. Recent kwam op dit gebied twee keer iets interessants in de wetenschappelijke literatuur, dus leek het mij aardig daar weer eens aandacht aan te besteden.
Extreme environmental tolerance and space survivability of the moss, Physcomitrium patens:

The Apollo 12 crew brought back Surveyor 3’s camera after 31 months on the Moon, and NASA reported finding live Streptococcus bacteria inside it, but later evidence pointed to contamination in Houston:

U denkt misschien: wat een rare titel voor een aflevering. Dat NZNZNZ refereert aan de oriëntatie van magneetdeeltjes. Inderdaad, deze aflevering gaat alweer over magnetisme. Vreemd genoeg is de aflevering "We leven in een magnetische tunnel" van 16 april 2024 al bijna twee jaar de populairste aflevering van deze podcast, maar dat geheel terzijde.

In de vorige aflevering hadden we het over die grote Saturnusmaan, Titan. Ook bespraken we het in 2028 te lanceren Dragonfly ruimtevaartuig, dat onderzoek zal gaan doen op Titan. Er is echter nog wat meer te vertellen over Titan...
