CHE SIGNIFICA SPACE JUNK IN INGLESE
Detriti spaziali
I detriti spaziali, detti anche detriti orbitali, spazzatura spaziale e sprechi spaziali, sono la raccolta di oggetti defunti in orbita intorno alla Terra. Ciò include tutto da stadi di razzo passati, vecchi satelliti, frammenti di disintegrazione, erosione e collisioni. Dato che le orbite si sovrappongono alla nuova nave spaziale, i detriti possono scontrarsi con la nave spaziale operativa. A partire dal 2009, circa 19.000 pezzi di detriti più grandi i 5 cm sono tracciati, con altri 300.000 pezzi più piccoli di 1 cm sotto i 200 km di altitudine. Per confronto, la Stazione Spaziale Internazionale orbita nella gamma di 300-400 km e sia il collisione 2009 che gli eventi antisatia 2007 si sono verificati tra 800 e 900 km. La maggior parte dei detriti di spazio è inferiore a 1 cm, compresa la polvere dai motori a razzo solido, i prodotti di degradazione della superficie come i fiocchi di vernice e il liquido refrigerante rilasciato dai satelliti RORSAT alimentati a nucleo. Gli impatti di queste particelle causano danni erosi, simili a sabbiatura. Il danno può essere ridotto con "Whipple shield", che, ad esempio, protegge alcune parti della Stazione Spaziale Internazionale. Tuttavia, non tutte le parti di una nave spaziale possono essere protette in questo modo, ad es.
