Hubble Space Telescope be kept in a clean room, powered up and purged with nitrogen, until a launch could be rescheduled. This costly situation (about per month) pushed the overall costs of the project even higher. This delay did allow time for engineers to perform extensive tests, swap out a possibly failure-prone battery, and make other improvements. Furthermore, the ground software needed to control Hubble was not ready in 1986, and was barely ready by the 1990 launch. Eventually, following the resumption of shuttle flights in 1988, the launch of the telescope was scheduled for 1990. On April 24, 1990, successfully launched the
Space Shuttle: A Journey into Space Orbit, Docking, Deorbit Burn, Reentry, and Landing, each with its own set of instructions to follow. The original Atari 2600 version came with an overlay since it made use of all the switches. In an April 1984 review for "Video Games" magazine, Dan Persons wrote: "Space Shuttle" is not a game for everybody. It requires a considerable amount of patience and, perhaps not too surprisingly, a considerable amount of brainpower. Players who seek the visceral thrills of the standard shoot'em-up may ultimately find this simulation's complexity frustrating. But those of you who are ready for a richer, more sophisticated experience
