In addition to depicting the ISS and Earth as oases for astronauts and humankind, the mission logo features the theme of water as the basis of life as we know it. Our planet is shown as a drop of water, resembling Earth as seen by the astronauts on the ISS. The importance of water for life is represented by the tree that grows out of the arms of a man. He is rooted in the Station and its scientific utilisation. Water flows through the man's arms and the branches of the tree. The rocket illustrates the Soyuz that will carry Frank De Winne to the ISS. A single white star symbolises how human exploration will eventually lead humankind to other planets.

Why OasISS

The name of the OasISS mission was chosen by ESA from a total of 520 suggestions received in response to a competition launched by ESA's Directorate of Human Spaceflight in September 2008. These were received from people in all ESA Member States.
The winning name refers to many aspects of the International Space Station as well as to human exploration, ranging from the exploration of deserts on Earth by European explorers, to the deserts we will find on other planets, where humankind might be able set up an oasis and provide a permanent human outpost to live on that planet. The ISS itself can be considered an oasis in space for its astronauts and cosmonauts, whilst Earth is often referred to as the Blue Planet and represents an oasis for humankind in the Universe.

The name also refers to the challenge to find an oasis, where human exploration is a challenge in itself.
OasISS also ties in with De Winne's role as a goodwill ambassador for UNICEF Belgium. In support of the UNICEF 2009 WASH campaign dedicated to water, sanitation and hygiene, several events will be implemented during his flight to draw public attention to the availability and cleanliness of water which is critically important for human life.

As De Winne himself stated, "Water is a scarce resource on board the ISS; responsible use and recycling in space can help develop efficient water processing applications for Earth, which are particularly important for the developing countries".

The winning mission name, OasISS, was proposed by Jan Puylaert from Ghent, in Belgium.
