my name is christopher hamilton, i am an associate professor my name is christopher hamilton, i'm anizona and a planetary volcanologist. we're here in geldingadalir, which is a new volcanic eruption that has occurred in southern iceland in reykjanes. iceland provides an ideal testbed for being able to test different kinds of drones for mars because the wonderful characteristics of the environment are actually very similar to what we would expect on mars. so, this has been a really exciting year for mars exploration. the drone ingenuity has demonstrated flight on mars for the very first time, being able to operate in a very thin atmosphere, about i% of what the earth's atmosphere is. is it still giving you that warning? no. the other drone we are using has a larger payload, has a number of different cameras and zoom functions, really beautiful, but also a lidar instrument. so, lidar uses light to be able to range the distance between the sensor that is emitting a set of photons and a surface. it's a world first to be able to use a drone—based lidar to image the lava flow and develop a

that was christopher hamilton. how spectacular was that? but relatively speaking there is going to be a lot of dry weather around to start the week — quite a cool start to the week as well. wetter, windier weather working its way in by the end of the week. so this is how monday shapes up, with most places largely dry, some spells of sunshine and a lot of cloud in the north—east of scotland, this cloud in northern ireland bringing rain for a time and some showers breaking out through the afternoon across parts of england and wales, some of which could be heavy, possibly thundery. light winds, so get yourself into some sunshine. it won't feel too bad. those temperatures, though, are a little disappointing for the time of year, 14—20 celsius. some of those showers in england and wales will continue on through monday night into tuesday. most other places will be dry with some clear spells. quite a cool, fresh start to the day on tuesday. sunshine and showers to take us through tuesday and into wednesday, but by thursday, friday and particularly
