Meet the man who sniffs things for NASA

George Aldrich sniffs things for a living. Not any old sniffing though – he does ‘space sniffing’.
He’s been at NASA for almost 40 years, and it’s his job to smell things just before they go to space. It’s part of the process by which NASA decides whether objects go on a space mission – they get this man to smell them and help them decide.
Is that a cool job, or just plain weird?
