Greetings all,
Here is the link to this year's Royal Society summer science exhibition which is free to access and if you cannot watch live is going to be put on YouTube so you can find it there after the event. Friday 17th looks like the main astro/space themed day but allsorts of interesting stuff new and historical all week.
