Jordi Isern Institut de Ciències de l’Espai (CSIC-IEEC) MSc in Economics of Science & Innovation Innovation & Challenges: Nanotechnology & Space (1) Historical perspective
Topics for a dissertation (25 min + 5 min discussion) 1.- Space tourism (Yeniceli/Okay) 2.- Economical impact of GPS systems (Appold/del Pozo/Slivko) 3.- Emergent Space Powers 4.- The GMES program of the EU 5.- Microgravity 6.- Space transportation & launchers 7.- Space tether & elevators 8.- Space debris 9.- Trends of space markets 10.- Space resources
The Fundamental Question: Pour quoi aller ailleurs si chez nous c’est mieux?
# Science & Technology are changing our world # Scientific discovery & technology development have a growing potential power # We have developped the technology to survey & utilize the space around the Earth => We are living in a 3D society!
# Benefits are huge: Global communication (telephone, television…) Global positioning systems (GPS, GALILEO… ) Efficient Earth exploration Improved science … # Drivers: Defence (USA-URSS military race…) Science Dreams

The Earth gravitational field is extremely strong The acceleration of the gravity at the Earth surface is: 9.8 m/s 2 All the terrestrial phenomena are affected by the gravity:
Why is so difficult to leave the Earth? We are leaving inside a gravitational well! The escape velocity is 11.6 km/s A huge amount of energy is necessary to escape from the Earth! ~ 72 MJ/kg or to lift a ship of 7000 tm 1 m from the ground
