Una piccola navicella sperimentale spaziale senza pilota decollerà mercoledì dalla Guyana francese. Il progetto dell’Agenzia spaziale europea (ESA) ha quale scopo testare nuove tecnologie per il rientro sulla Terra di questi velivoli.
IXV – Intermediate eXperimental Vehicle, questo il suo nome, misura cinque metri di lunghezza e pesa due tonnellate. E’ dotata di ali e volerà come un aereo al ritorno dallo spazio, dove ci rimarrà 100 minuti. Salirà sino ad un’altezza di 450 chilometri.
Il suo passaggio nell’atmosfera avverrà a una velocità di 27'000 chilometri orari. "Questa fase", ha spiegato il responsabile del progetto Giorgio Tumino, "è una delle più difficili da realizzare (…). Il Vecchio continente eccelle nel mettere satelliti in orbita, ma in questo campo dobbiamo fare progressi, siccome siamo dietro a Stati Uniti, Russia e Cina".
