We've got this very rare astronomical event where Saturn's moon Titan will pass in front of a bright star. And so for a very brief short period of time lasting only about four minutes, Titan's atmosphere will be illuminated briefly with the star behind it. We're talking about billions of kilometers distance, so we're trying to measure fractional changes in the size of an atmosphere, billions of kilometers from Earth. There could also be life on Titan. It's believed that Titan has liquid water oceans buried under frozen methane gas. And some of these chemicals were not just present in the early Earth, but our Earth was dominated by these very exotic chemicals. So the type of science that was at Cotelescope exploits, we call it transient astronomy, things that happen over a short period of time. It was always recognized that the plane, of course, being a mobile platform, can position itself at an optimal location. Often these events also happen over water, like over the Pacific Ocean or over the Atlantic. So it's not always that we get lucky that we can recruit other telescopes like ZEDCO, that happen to be able to see such a transient event. Sophia can fly down on the less, that's I guess the biggest advantage. The biggest challenge is going to be the weather. We could end up with a four minute window that is exquisite, and we can do this fantastic experiment, and everyone's going to be jumping up and down and joy. Or it could be clear all night and we get cloud cover, and it all will end up in tears, and we'll be going, oh no, so we just, we really don't know. It's the risk you have to take with this sort of science, because it's observational. .
