Rank 11 documents the Hubble Space Telescope — the 11,110 kg Great Observatories flagship deployed from Space Shuttle Discovery on STS-31, 25 April 1990, at 540 km orbit. Lyman Spitzer's Large Space Telescope concept became operational reality with a 2.4 m primary mirror, though initial spherical aberration required Servicing Mission 1 in 1993 to install corrective optics. Five shuttle servicing missions upgraded instruments from WFPC2 to WFC3, ACS, COS, and STIS, enabling Deep Field images that measured universe expansion and transformed public astronomy. Goddard and STScI operations continue into the 2020s with more than 1.5 million observations logged. Heritage Collector renders the open-aperture tube hero, Canadarm astronaut scale figure, and vertical title spine exactly as the master PNG dictates.
