Got some spare time?

Like about 520 days?

If so, the European Space Agency may have just the thing for you. In preparation for future Mars missions, the ESA is looking for candidates to participate in "up to three isolation and confinement studies".

The main qualifications are:

• Aged 25-50 years
• Good health
• High motivation
• Height up to 185cm
• Background and work experience in one of the following fields: medicine, biology, life support systems engineering, computer engineering, electronic engineering, mechanical engineering
• The working languages during the studies will be English and Russian, therefore fluency in one and working knowledge of the other language is highly desired.

Oh, and "For successful completion of the entire study including training before and follow-up after the isolation, the respective volunteer will receive a fixed compensation that is in line with international standards for participation in clinical studies."

An article about it is here.
