The Science Programme has a long and successful history, starting with the Horizon 2000 Programme that lasted 20 years, from 1985–2005.
This was followed by the Horizon 2000+ Programme from 2005–2015, leading to the current Cosmic Vision Programme to 2025.
The missions of the Cosmic Vision Programme will provide answers to four fundamental questions of astronomy, Solar System science and fundamental science:
What are the conditions for planetary formation and the emergence of life?
How does the Solar System work?
What are the physical fundamental laws of the Universe?
How did the Universe originate and what is it made of?
