Definision de volo spasiale

I criteri par determenar el signifegà de "viajo inte el spàsio" i ze defarenti inte łe vàrie culture dei sìngułi paezi coinvolzesti. Inte i Stati Unii i ze considerai astronàuti chełi che i sorpasa un'altitùdene de 50 mìlia (sirca 80 km), in Rùsia par voło spasiałe se intende na trajetòria orbitałe (òrbita zeosèntrega) o sia che el veìcolo el gàpia da fare almanco na volta da torno de ła Tera.

La Federasion Internasionałe Aeronàutega (FAI) invese ła definise vołi spasiałi cuełi che i sorpasa i 100 km; par sta motivasion el nùmaro totałe de astronàuti i diferise da fonte a fonte. Al 20 de zugno del 2011 un totałe de 529 persone łe ze andae inte el spàsio, secondo ła definision americana, andove che i ga totałizà pì de 30 000 dì, includesti pì de 100 dì de pasejae spasiałi. A l'istesa data invese i el nùmaro el devien 523 i "astronàuti" secondo ła FAI.
