And the exhibition tells a fantastic story.
About astronauts with Down's syndrome who explore life on earth.
In October 2016, 7 astronauts from a distant planet are landing on earth.
They call themselves the "Second Mission".
They all have Down's syndrome.
5,000 years ago, the first astronauts of their kind have landed on earth.
Now, the Second Mission has the task to check on the first settlers and see how their descendants are living today.
As life-sized comic figures, the astronauts join the visitors on their tour through the exhibition.
The illustrator Vincent Burmeister has created the fantastic comic figures.
In 7 rooms, the Second Mission explores how people with Down's syndrome live today and how they used to live in the past.
They discover traces of people with Down's syndrome in the centuries before Christ, in the Middle Ages and in the 19th century.
They learn about the English doctor, John Langdon Down (1828–1896), who lent his name to Down's syndrome.
Throughout his life, he tried to support people with Down's syndrome.
The exhibition also tells about people with Down's syndrome who were murdered in Germany during the Nazi era.
The Second Mission also looks at new scientific research about trisomy 21.
The exhibition wants to ask questions.
About differences and similarities.
About diversity. And about how people with and without a handicap can have a good life together.
The exhibition is a joint project.
Many people, some with and some without Down's syndrome, have created it together.
During the whole exhibition period, people with and without Down's syndrome will give joint tours of the exhibition 3 times a week.
