7. Competition for secondary students Mark this date: 15 September 2011 Launch of competition for secondary students to explore the high-energy Universe 4 projects to choose from relating to Integral, ESA’s gamma-ray space observatory Prizes include chance for students to present project at 9 th Integral Science workshop, Paris in October 2012

8. Integral ESA’s International Gamma-Ray Astrophysics Laboratory Launched 2002 Observes some of the most energetic phenomena in the Universe. Maps gamma-ray sources across the galaxy

9. Competition projects Project 1: Observe Make observations of the variable companion stars in high-energy binary systems. Project 2: Research Research the Dynamic centre of the Milky Way, to determine which exotic high-energy sources are present. Project 3: Design Design a high-energy astronomy mission to investigate some of the most powerful phenomena in the Universe. Project 4: Build Build a scale-model of the Integral spacecraft using materials of your choice.
