for more than 50 years, but the man who plays him has remained firmly on the earth, until now. william shatner will, if everything goes to plan, soon be boldly going where no nonagenarian canadian actor has ever gone before. in a statement he said... and this will be his uss enterprise — blue 0rigin�*s new shepherd rocket, which had its first successful flight with a crew injuly, this year. at 90 years old, william shatner will become the oldest person ever to fly into space, which must raise at least some concerns. being 90, just like kinda getting out of bed in the morning is a bit of a risk, i suppose. so anybody getting on a spacecraft that�*s being launched off earth via rocket —

that�*s a dangerous thing to do, you know, we aren�*t in the age of star trek where this stuff is routine. his will be a ten—minute voyage, rather than a five—year mission. it�*s not quite the final frontier but it�*s pretty close. tim allman, bbc news. after a couple of days of sunshine and showers we are now seeing an area of low pressure moving in from the south—west that�*s mainly affecting england and wales. that�*s bringing with it some heavy rain and it�*s also strengthening the winds too. we start with some heavy rain across east anglia and the south—east but that will soon move away. but for northern england, it will be wet through much of the day. that rain continues to push into the south—east of scotland. for wales, the midlands and southern england it may brighten up, there may be sunshine but also showers. around the area of low pressure we have strong winds, particularly where it�*s wet, and it will make it feel cold. some of the wet weather could push into the north—east of scotland later, but we are missing the worst of the weather across western scotland and northern ireland

with no more than one or two showers and some sunshine. the area of low pressure bringing the wet windy weather is slowly going to move away during wednesday, and the next system will be pushing in from the atlantic. we started with wind easing on for eastern england. the winds will ease, cloud and showers move away, sunshine comes out for many but then we look to the west. it will be clouding, then rain pusing in through northern ireland. clearing through the day, than in the afternoon rain will push in mainly for northern ireland. ahead of that, it should be a little bit warmer. temperatures of 16 or 17 degrees. there�*s warmer weather on the way later in the week. the weather front parking off scotland and northern ireland, high pressure into the south—east of the uk, so drawing drawing in a south—westerly wind all the way from the tropics. that�*s going to bring some higher temperatures, probably bring a lot of cloud, mind you, on thursday, and rain and drizzle at times across scotland and northern ireland.

some dampness here and there across western england and wales with brighter skies further east. even with a lot of cloud, temperatures could reach 19 degrees in belfast and newcastle. could make 20 or so across other parts of england and wales. we still have that weather front hanging around a bit across northern parts of the uk. the position of the rain keeps chopping and changing, there�*s still the threat of rain for northern ireland, perhaps first thing in northern england as the rain moves northward into southern and central scotland. these areas not quite as warm, but with lighter winds and more sunshine breaking through across england and wales, it will be very mild, temperatures of 20 and 21
