Two international secondary schools in Matera and Potenza, Italy, took part in live link up with ESA’s Erasmus Centre at ESTEC this month, to talk about ESA’s role in the International Space Station and our Lunar Exploration web documentary. This one-day ‘space-twinning’ event was organised by ESA as part of the OneClass! project, supported by ESA’s ARTES Competitiveness & Growth programme.
