How many people are in space right now? It's a good question, and you can get a straight answer to it over on the ingeniously-named website howmanypeopleareinspacerightnow.com.
As you can see, there are currently nine people in space: we applaud the sterling work of commanders Pavel Vinogradov and Zhang Xiaoguang and flight engineers Alexander Misurkin, Chris Cassidy, Fyodor Yurchikhin, Karen Nyberg, Nie Haisheng, Luca Parmitano and Wang Yaping.
However, once Virgin Galactic begins flying people to space - and we're getting closer and closer - the website is going to have a delightful problem. In the future we hope to be taking new people into space every day. Now that's a lot of website updates.
I look forward to one day soon when our Virgin Galactic astronauts names are up on howmanypeopleareinspacerightnow.com - including my children Holly and Sam of course.
