good morning. it s thursday october 20th. our main story. the prime minister s position is looking increasingly vulnerable today after some of her own mps called for her to resign. it followed a chaotic day for the government with the resignation of the home secretary, accusations of bullying, and confusion over whether the chief whip had resigned. our political correspondent ione wells reports. reporter: is this a coalition of chaos, mr schapps? - another day, another new cabinet minister. grant shapps, sacked just six weeks ago by liz truss, returns as her new home secretary. look, obviously it s been a turbulent time for the government, but i think the most important thing is to make sure that people in this country know that they ve got security and that s why it s a great honour to be appointed as home secretary. he stepped up after suella braverman stepped down, resigning over two data breaches. but have a look at her resignation letter. she wrote to the prime minister
details on that later. back to you. thanks very much. offshore wind farms have been helping to power britain for many years now, and traditionally these are built onto the sea floor, meaning they can only be placed in relatively shallow water. yes, but now the race is on to develop turbines that can be placed in deeper water, where the winds are often stronger. our climate editor, justin rowlatt, reports. there s always a long boat journey when you go out to an offshore wind farm. you get stronger winds further out to sea. conventional wind turbines are built up from the sea bed. they need shallow water up to about 60 meters deep, which is why these turbines represent a wind revolution. now, i know these wind turbines look pretty similar to the kind of offshore wind turbines you ve seen before. but these really are different. these are an engineering triumph. each one of them is almost 190 metres high. that s about the same height
i just hope he keeps doing this. it entertains me to no end. it is like the moon landing except this one is real. the robotic explorer curiosity has touched down on mars on a mission to learn if life ever existed on the red planet. folks, it is folks at the nasa jet propulsion lab jumped for joy at 1:32 a.m. mars time. it was only three hours time difference, surprisingly. one dude seemed to get the news light years ahead of everyone else. the attempt is good. touchdown confirmed. we are safe on mars. the landing was an engineering triumph. that s curiosity cut through the martian atmosphere. it is 13 miles per hour and then the cables gently lowered the rover to the ground. nasa released this video of the historic landing.
