Spitzer Uzay Teleskobu (SST) (daha önceki adı Kızılötesi Uzay Teleskobu Tesisi, SIRTF), 2003 yılında uzaya gönderilen ve 30 Ocak 2020'de kullanım dışı bırakılan bir kızılötesi uzay teleskopuydu.[1][2]

720 milyon dolarlık Spitzer,[3] 25 Ağustos 2003 tarihinde UTC ile 05.35.39'da Delta II 7920H roketiyle Cape Canaveral SLC-17B'den fırlatıldı.[4] Fırlatma öncesinde planlanan görev süresi sıvı helyum desteği tükenene kadar, beş veya biraz daha fazla yıla uzayabileceği beklentisiyle 2,5 yıl olarak belirlenmişti. Bu süre 15 Mayıs 2009'da doldu.[5] Teleskopu çok düşük sıcaklıklarda soğutmak için gereken sıvı helyum olmadan, araçların çoğu kullanılabilir olamayacaktı. Buna rağmen, IRAC kamerasının iki kısa dalga modülü soğutucu madde tüketilmeden önceki hassasiyetle çalışmaya devam etti ve Spitzer Warm Mission olarak 2020'nin başlarına kadar kullanıldı. Warm mission sırasında IRAC'ın iki kısa dalga boyu kanalının 30 K'da çalıştığı, nominal görevle karşılaştırıldığında çok az veya hiç bozulma yaşamayacağı tahmin edilmişti.
