Due to this situation, the key element failure possibility would conduct to the orbital telescope final failure, before its re-enter in the atmosphere around 2028. In addition to the current crisis of the US space observatories, with constant delays and cost overruns of the James Webb telescope development, the natural complement and substitute for the Hubble. This situation leaves NASA’s orbital observatories program in a delicate situation; on one hand it’s impossible to count on the Space Shuttle (STS) to repair and maintain the old telescope in orbit, since its retirement in 2011, and on the other hand, the use of the new manned spacecrafts Crew Dragon and CTS-100 Starliner by 2020 isn’t too viable, due to delays and cost overruns in the CCDev-CCP program .
