Sandra Magnus is a US astronaut with the National Aeronautics and Space Administration (NASA) and is now the executive director of the American Institute of Aeronautics and Astronautics. Sandra always wanted to become an astronaut and has had a lifelong passion for science and exploring how the world works. On the space station she says that every day is about trouble-shooting, and sometimes it doesn't seem very organised, there is a lost and found plastic bag, "I always thought that was rather amusing because that means there were things on the station that were missing parts".

Samantha Cristoforetti made history when she became the first person to make an espresso in space. "We got to try the first freshly brewed espresso coffee in space" she says proudly. Born in Milan and raised in the province of Trentino in Itlay, Samantha speaks four languages including Russian. She has a second degree in aeronautical sciences and a masters in mechanical engineering. She is a captain in the Italian air force, a qualified jet-fighter pilot and has been an astronaut with the European Space Agency since 2009, the first Italian woman to take the role.
