A principal focus of the mission was Fuglesang’s spacewalk as a Mission Specialist on the STS-116 Space Shuttle flight (ISS assembly mission 12A.1). Fuglesang also performed experiments, educational and public relations activities that were part of the Celsius Mission.
The principal graphic element of the logo is a map of Scandinavia represented in lighter blue stripes and one darker blue (broken) stripe. This darker stripe marks the flight path of the Space Shuttle Discovery, which is represented at the top of this darker blue stripe.
The crossover of these images indicates the national feel of the mission with ESA astronaut Christer Fuglesang coming from Sweden and activities during Scandinavian flyovers of the Shuttle involving institutions and students on the ground. The stripes also symbolise precision, scale and measurement with the darker stripe indicative of a thermometer, tying in with the background of the mission name shown to the right. The upward slanting direction of the darker stripe and the Shuttle furthermore hints at the dynamic nature of the mission and the progress that will be made with relation to the assembly of the ISS and on scientific grounds.
Furthermore with the colours used in the logo matching the chosen colours of the European Space Agency, this shows the wider European nature of the mission. This is again indicated by the appearance of the ESA logo in the bottom right hand corner.
The Celsius mission takes its name from the famous Swedish scientist and astronomer Anders Celsius (1701 – 1744), who is most noticeably famous for his invention of the standard international temperature scale that bears his name.
Celsius found it important to share and learn more about science outside Sweden, working in France and Germany. He had a thirst for knowledge about the aurora borealis and his collection of 316 observations was published in 1733. In line with this Fuglesang will be involved in a number of education activities during the mission and was previously involved in the SilEye, experiment which investigated light flashes in astronauts eyes on the Mir Space Station between 1995 and 1999.
Both Celsius and Fuglesang share a drive for exploration. Fuglesang by crossing the Atlantic Ocean by boat and going on mission the International Space Station. Celsius with expeditions to the northern part of Sweden and Norway, taking measurements that helped to confirm Newton's belief that the Earth was an ellipsoid flattened at the poles.
