Things are changing. The BBC's Spaceman has been assigned a new ship for his thoughts. So, as of today, this blog is moving to a new home, and taking on a format that you will recognise if you are a regular reader of the BBC News website. The content of the blog won't change, however. You'll still find Spaceman's musings on all things in orbit. But one of the advantages of the change is that it will make it easier for you to follow everything the Spaceman gets up to - online, in video and audio, and soon on Twitter. You can follow me here.
