functioning, it still keeps orbiting, which is a problem for the useful ones. satellites when they _ for the useful ones. satellites when they die _ for the useful ones. satellites when they die on _ for the useful ones. satellites when they die on these - for the useful ones. satellites| when they die on these orbital highways, theyjust keep on going at these very fast speeds. some of the relative speeds. some of the relative speeds between satellites that are criss—crossing each other is like 15 times the speed of a bullet, so that's pretty gnarly to think about. and every once in a while two of these things find each other in space at these very high speeds, collide and break up into very small pieces and that sort of stuff. and most of the things that could damage a satellite that's providing a service or a capability that we care about —most of those itaims to it aims to collect information from many different origins like telescopes and radars, physical sensors and news articles and turn it into usable data for developers. imagine a massive machine—readable spreadsheet where all the data is lined up

so the column headings make sense. it is one of many companies and space agency is taking part in the summit for space sustainability at london's science museum. these are the people hoping to clean up up are the people hoping to clean up up there and it is harder than you think. because you can't exactly use a vacuum cleaner in a vacuum. one solution is on orbit surfacing. removing old satellites and re—fuelling very hot mechanic and tow truck in space. another outfit shows for arms to catch and how the dead satellite before coolly pulling it into the atmosphere to burn it up. it sounds complicated. well, it is rocket science. it it sounds complicated. well, it is rocket science.— is rocket science. it is hard technically _ is rocket science. it is hard technically so _ is rocket science. it is hard technically so removing - is rocket science. it is hard technically so removing a l is rocket science. it is hard - technically so removing a space satellite with some close, robotic arms and nets is hard to do because operating a from hundreds of miles away is tough to do but it is also tough

you felt like you are flying. did you really feel weightless? not really. i think my brain was trying to take its best guess that what is going on. they're trying to get as many people involved as possible. it is going on to belfast and edinburgh. that is it from us. i'm going to make lara try to feel like she is flying. see you. feel like she is flying. see ou. �* , , hi. we are forecasting rain this weekend, but not an awful lot of it, and most of it will fall

in western areas of the uk, particularly the northwest. there'll be some sunshine around, too, and many of us will actually escape the rain all together, rain that we really need because the gardens are very parched. so, here's the low pressure that will approach us. in fact, it's approaching us right now, the unsettled weather out towards the west. but ahead of this weather front in east anglia, in the southeast, we'll see very warm weather as south—westerly winds develop and tap into some of that heat that's across france right now. but let's have a look at the here and now and the rain approaching northern ireland through early saturday morning. elsewhere, it's generally dry, quite a bright start to the day, a mild one too, 17 celsius in london, 15 celsius in hull and around 1a celsius in the lowlands of scotland. so, the forecast for saturday shows increasing amounts of cloud out towards the west. you can see that rain moves in, it's a fairly broken area of rain, so it'll wax and wane through the morning, into the afternoon, and in fact, if anything, the skies may clear in northern ireland middle of the day, and it'll be quite sunny and pleasant with temperatures up to 20 degrees. it'll stay dry generally east of the pennines, across east anglia and the south coast. so, a fine day for portsmouth, southampton, brighton, and temperatures will be in the low 20s.

but towards evening, notice this lump of rain heads towards northern ireland and southwestern scotland, and that could really be quite heavy for a time saturday night into sunday. here's sunday's weather forecast. so, the low pressure, slow—moving and just to the northwest of us, brisk south—westerly winds pushing in clouds and showers, but most of the showers escaping east anglia and the southeast, where warm south—westerly winds will draw in that heat from france. so, temperatures temporarily reaching 30 celsius there in norwich, and by that, i mean it'sjust going to be the one day. in fact, by the time we get to monday, and this is monday's weather map, the low pressure moves out into the north sea. on the back side of it, the winds are coming in from the north. so fresher conditions sweep across the country and it'll cool off. so, here's the forecast for a couple...for a few cities, then, northern areas staying a little unsettled into monday and fresher. further south, also cooling off, but staying generally dry. bye— bye.
