 Ian Wright, pleased to meet you. And you, not the other Ian Wrights. I'm just a mere Ian Wright. Just a mere Ian Wright, Professor, Doctor, both of those things, but Ian Wright for today, what is this? This is a 3D shaped model of something called 67P or Turium of Garazimenko. It's a comet that the Rosetta spacecraft has been tracking now for several months. Indeed, we set off 10 and a half years ago to get to this comet. And we're getting closer now. We're about 30 kilometers away. And in a few weeks' time, we're going to try and land on it. Sorry, rewind that bit. I mean, which bit? Because it looks like a kind of mushroom crossed with nuclear explosion. It doesn't look very landable. Yeah, it is a bit scary for landing on. And at some point, we'll actually take a manoeuvre, which actually drops part of the spacecraft, a little land at Kofili, off the main spacecraft and down onto the surface. And the reason is we want to know what it's made out of. Or at least I do. That's my personal interest. And you've been involved from the beginning? Yeah, I still have the designs for my instrument. They're not exactly the back of a beer mat, but they're a sheet of A4 paper, a sketched in boron. And that has the date of 1993 on it. You know, I've had projects before where it's going to end a month later. And that seems like a long time. I'm waiting 10 years. Must be phenomenal. It's a strange thing. I don't like to give the impression I've been sitting at my desk with my feet up, you know, drumming my fingers. We've got plenty of other things to do. Not least of all, perhaps people don't really understand it. In actual fact, when you launch a spacecraft, there's still a lot of things to do with your actual instruments and so on that you haven't yet done. Because you know you have plenty of time to do them back on the ground. And it may be that you actually redefine the ways in which you operate the instrument. And then, of course, you telemetre that data up to the spacecraft and upload some new software, et cetera. The parameters and all of this and just the numbers involved, just phenomenal. How? There must be 1,000 things that can go wrong every day. Yes, it is a risky vein shift, a space exploration. Expensive? It's expensive. But you know, it's not that expensive when you think about the number of people it actually employs. And, of course, the spin-offs that come from it. I mean, that's not necessarily why we do it. But there is a payback in many different ways. I mean, certainly our instruments that we developed and the people that we trained to make those instruments, I know working in all different kinds of areas, all walks of life. What do you think it's made of? Well, we kind of know what we think it's made out of. We know it's made out of water ice and the black surface is because it's covered in organic compounds. And so what we want to know is the detail of that. And in particular, we're interested, for instance, is the water that makes the ice in any way related to the water on Earth. And we can do that with some very specialized measurements that we're going to make. And of course, if we can make that connection, then we can look at the black stuff and say, well, those are the kind of organic materials that came down to the surface of the primitive Earth from which life ultimately developed. So it's like we're kind of looking back in time to a point before life existed at the very ingredients from which life evolved. And that's quite a fascinating thing. Huge. I mean, good luck seems too smaller thing to say. But good luck. Good. The Deep Space Network landing probes on objects moving 15 kilometers a second. This is science fact you're talking. Sounds like science fiction. Yeah, yeah. No, no, this is your job. It's the day job. Yeah.
