IFLScience visited the Space: Could Life Exist Beyond Earth exhibition at the Natural History Museum, London, recently and we were curious to come across opportunities to take in the scents of asteroid Bennu, Mars, and even Saturn’s moon Titan. We understand that space smells, in an abstract way, we’ve even covered it before, but being able to get an actual whiff sparked many questions. Who created these smells, based on what, and how?  

Enter Marina Barcenilla, astrobiologist and fragrance designer – and now major exhibition contributor – with her own artisan perfumery AromAtom, where she uses chemistry to create the smells of cosmic environments from the surfaces of planets to distant nebulae. So, we asked Barcenilla: How does one become a perfumer for the stars?
