NASA’s new moon rocket has finally started – and there are two dolls on board, because the flight through space carries many risks for people, from clouding of the eye lenses to cancer. Radiation biologist Christine Hellweg says: A safe journey to Mars would still be impossible.

On Wednesday morning at 7.47 a.m., the new NASA rocket SLS to the moon took off, still without astronauts on board, but with two dolls from the German Aerospace Center (DLR). Scientists want to use them to research health hazards in space. Radiation biologist Christine Hellweg from DLR believes that there are still a few unanswered questions before humans can permanently colonize the moon or land on Mars.
