This is very cool. In some sense, we have a moral imperative to spread life in the cosmos.

Your experiment involves creating flies that could survive on Titan. I understand that Titan is incredibly cold so the flies have to gradually get used to the very low temperatures but what would be the impact of Titan’s orange sky and the low frequency radio waves that emanate from Titan on their bodies? And how do you prepare them for that? The project involved adapting the flies for a range of environmental conditions that are very different to those found on Earth. The cold is the most obvious along with the different atmospheric composition. There is also increased atmospheric pressure, radiation, chromatic characteristics and so on. To reach what could be conceived as the end of the project I would need to condition the flies for all of the characteristics of Titan. The radio waves experiment has been earmarked for a future stage in the project so I haven’t got too much to say about that right now. However, the chromatic adjustment has been something I’ve been working on over the last couple of years. The natural phototaxis of Drosophila – its instinct to move towards a certain type of light – is geared towards the blue end of the electromagnetic spectrum. To overcome this I kept the flies for a year under a Titan analog orange light before testing for adaptation. The selection experiment was modelled on a Y-Trap apparatus, a simple way of offering an organism 2 choices. The flies crawl up a tube and are faced with a junction offering orange light in one direction and blue light in the other, each tube ending with another non-return trap. Any flies taking the orange option are considered adapted and kept for breeding. Repeated iterations of the project smooth out random events.
