the first earthquake hit. many were killed where their bodies were found still in their beds. another quake hours later brought fresh damage. but should advanced new technology have given people more time to escape a system which was already supposed to be working successfully? here in california, google has spent years creating an earthquake warning system designed to alert people before an earthquake strikes. it works on any android phone. that s about 80% of all of the phones in turkey. and this is google s explainer on how it works. android phones have these tiny accelerometers built into them, which can sense earthquakes. people will now be able to have their phones become part of this network of mini seismometers looking for earthquakes around the world. we call this the android earthquake alerts system.
the head of the un wants action but so much depends on national governments. polls suggest the public nshares a sense of urgency about the need for change, but what s their attitude to paying for it? we ll hear the views of experts and get a sense of the climate change policies that could be on offer at the next election. also tonight. android phones have these tiny accelerometers built into them which can sense earthquakes. big data would you bet your life on it? we have evidence a google app that was supposed to warn of eathquakes may have come up short. he did not receive any alert? nothing on your phone? is donald trump about to be indicted for attempting to overturn the result of the 2020 election? we speak to a legal expert in the know. and we talk to the survivor of a conflict that ended 70 years
collecting important data. most of those sensors are getting an idea of whether its environment is going to be ok for people. so things like radiation sensors, motion sensors, accelerometers, things like that, things that we as human payloads are going to care a lot about. and this is vital because if this mission is a success, astronauts will join the next ride, taking in these views for themselves, like this one with the earth as a pale blue dot. but there s some way to go yet. and nasa will be assessing every stage of the spacecraft s journey before it returns home with a splashdown in the pacific ocean on the 11th of december. rebecca morelle, bbc news. let s get some of the day s other news. a fire at a factory in china s henan province has killed at least 38 people. state media says criminal suspects have been taken into custody, but gave no other details.
in close, just 130 kilometers. that s 80 miles above the lunar surface. then it enters a much larger orbit, swinging more than 65,000 kilometres, about 40,000 miles beyond the moon. that s further than any spacecraft built for humans has ever flown. during the seven weeks orion is in orbit, nasa will collect important data and check how the spacecraft is performing. this is a test flight, so there are no people on board. instead, there are mannequins covered in thousands of sensors collecting important data. most of those sensors are getting an idea of whether its environment is going to be ok for people. so things like radiation sensors, motion sensors, accelerometers, things like that, things that we as human payloads are going to care a lot about. and this is vital because if this mission is a success, astronauts willjoin the next ride, taking in these views for themselves, like this one with the earth as a pale blue dot.
