Astronaut André Kuipers waving to the camera from the Cupola module on the International Space Station.
This image was taken by André himself and sent to his friend Emma back on Earth via a web service.
André decided to send a postcard to Emma in the Netherlands in celebration of her 11th birthday. Emma suffers from Maroteaux–Lamy syndrome, a rare, incurable disease.
In addition to sending this postcard to his friend, André hopes to raise awareness for this syndrome and other rare diseases.
