15 2016: Observatory Assembly: Three main components of observatory completed (instruments, telescope, spacecraft) 2017: Observatory Testing: Three main components of observatory to be tested and readied for assembly (instruments, telescope, spacecraft) into single unit 2018: Kourou Countdown: All parts of the observatory will be brought together, tested and readied for launch in Kourou, French Guiana

16 2017: Observatory Testing: Three main components of observatory to be tested and readied for assembly (instruments, telescope, spacecraft) into single unit -- most challenging year to date of the I&T phases. Science payload -- ambient launch environment All flight sunshield membranes and covers delivered to Northrop, being readied for integration. Numerous, but not show stopping, issues with final manufacturing and testing of sunshield components (e.g., membrane tensioning system parts coating, mid-boom deployment test over current instance.) Ground system (STScI) progressing well Spacecraft integration nearing completion proceeding well
