ESA astronaut Umberto Guidoni (IT) was the first European to fly to the International Space Station on the Space Shuttle Endeavour STS-100 mission in April 2001.
The STS-100 (6A) patch reflects the complex interaction of robotics and extravehicular activity on this mission. Spacewalks were conducted to deploy the ISS Remote Manipulator System (RMS). The EVA helmet frames the patch, with the Canadian-built RMS shown below the visor. Reflected in the visor is the Shuttle Endeavour, with the ISS rising above the horizon at sunrise. In the Shuttle's payload bay is a Spacelab pallet, holding the RMS and the Space Station Ultra High Frequency Antenna, and the Italian-built Multi-Purpose Logistics Module 'Raffaello'.
US, Russian, Canadian and Italian astronauts are represented by their stylised flags in the lower part of the patch. Ten stars represent the children of the STS-100 crew and the future of space exploration.
