Over five spacewalks, astronauts installed two brand-new science instruments: the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3). They also prolonged Hubble's life by installing new batteries, new gyroscopes, a new science computer, a refurbished fine guidance sensor and new insulation on three electronics bays.⁣ ⁣ Credit: NASA⁣ ⁣ #Hubble #NASA #Telescope #Upgrade」5月20日 5時43分
