I see the Natural History Museum Meteorite Group have started a blog about their work. There are only a couple of posts so far, but you are invited to comment and ask questions. Nice one NHM Meteorite Group.
I'm not too sure about navigating about the blog, but the link should be a reasonable starting place.
Follow our blog to find out why we study meteorites and how they are helping Museum scientists unravel the secrets of our solar system.
