Introducing Blue Dot
Blue Dot is the name of ESA astronaut Alexander Gerst’s six-month mission to the International Space Station launching May 2014.
He will serve as flight engineer for Expeditions 40 and 41. Alexander will be the sixth ESA astronaut on a long-duration mission in space and the third astronaut of German nationality to live on the International Space Station.
Alexander is leaving Earth from Baikonur cosmodrome in Kazakhstan 28 May 2014. He will fly on a Soyuz spacecraft to the International Space Station with Russian cosmonaut Maxim Viktorovich Surayev and NASA astronaut Gregory Reid Wiseman.
His mission is called Blue Dot after the American astronomer Carl Sagan's description of our faintly visible planet as “a pale blue dot” as seen on a photograph taken by NASA’s Voyager six billion kilometres from our planet.
Alexander was a geophysicist and volcanologist before he was chosen as an ESA astronaut in 2009. His scientific background will be of great help performing the international experiments he has planned during his 166-day stay on humankind’s weightless laboratory.
Blue Dot mission’s extensive scientific programme includes experiments in physical science, biology, and human physiology as well as radiation research and technology demonstrations. All experiments chosen make use of the out-of-this-world laboratory to improve life on Earth or prepare for further human exploration of our Solar System.
When not performing science Alexander will work with his colleagues to maintain the Space Station and keep the orbital outpost running smoothly for the crew of six.
Spacewalks and space freighters
Alexander has one spacewalk planned during his stay. In addition six space freighters are scheduled to arrive at the International Space Station during Alexander’s stay. The ESA astronaut will be prime operator overseeing the docking of Europe’s last Automated Transfer Vehicle (ATV),Georges Lemaître, and be responsible for unloading the tonnes of cargo. ATVs just like their Russian counterpart, Progress, dock automatically with the Station.
The commercial American freighters Dragon and Cygnus are captured by the Station’s robotic arm and Alexander has spent many hours training for this complex operation.
Inspiring science and education
From his unique vantage point, Alexander aims to inspire the next generation of engineers and scientists as he carries out his duties. The astronaut will show youngsters the importance of environmental protection, the behaviour of soap bubbles in microgravity and how hard it is for spacecraft to land on comets.
When Alexander returns to Earth, he will be the first astronaut to fly directly to Europe after landing in the steppes of Kazakhstan. Post-flight examinations and research activities will be conducted in Cologne, Germany.
Early access to Alexander will allow ESA doctors to monitor his health very closely and to start his fitness and rehabilitation programme quickly. Scientists will also benefit from continuing with their scientific examinations soon after landing.
