La NASA potrebbe privatizzare ed affittare ai privati uno dei suoi telescopi spaziali più celebri, Spitzer, a partire dal 2019, quando si esauriranno i fondi stanziati per la sua attività, prestandolo ad un'istituzione accademica o ad un operatore privato.
Uno dei più importanti e recenti risultati raggiunti da Spitzer, come riporta il sito Spaceflight Now, è stata la scoperta del sistema Trappist-1, formato da sette pianeti simili alla Terra, che detiene il record per il maggior numero di pianeti potenzialmente abitabili in orbita intorno ad una singola stella. Lanciato nell'agosto 2003 per una missione che inizialmente doveva essere di cinque anni, il telescopio spaziale a infrarossi si sta lentamente allontanando dalla Terra mentre orbita intorno al Sole e quindi le comunicazioni cominciano a farsi più difficili.
Nel 2016 la NASA ha deciso di continuare a finanziare la missione di Spitzer fino all'inizio del 2019, mantenendola attiva mentre viene ultimata la costruzione del nuovo telescopio spaziale James Webb, un progetto da 10 miliardi di dollari.
