20 Years of Children's University - Katharina Brinkert was part of Humans on Mars.

The children from Bremer high schools were initially shocked to hear how hostile the Martian environment is. Do jackets worn over the space suit help against the incredible cold temperatures? How much chocolate would fit into a rocket - and would that be enough for the round trip? The students were enthusiastic and learned a lot from Katharina Brinkert - including how her research on Earth will be useful.
