The second mission of this video game requires players to build a space station. The object of Space Shuttle Project is to successfully launch and fly one of NASA's historic Space Shuttles as a shuttle commander. Gameplay is composed of several different types of missions, each broken up into short mini-games. [2]
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
Westerhout 50 (W50) or SNR G039.7-02.0, also referred to as the Manatee Nebula, [1] is a supernova remnant located in the constellation Aquila, about 18,000 light years away. In its centre lies the micro-quasar SS 433 , whose jets are distorting the remnant's shell.
The nebula is rich in carbon, and is a very interesting object for the study of carbon chemistry in dense molecular material exposed to strong ultraviolet radiation. [18] The spectrum of NGC 7027 contains fewer spectral lines from neutral molecules than is usual for planetary nebulae.
Based on the expansion rate, the estimated age of the nebula is 3,080 years. [5] The central star of the planetary nebula is a subdwarf O star with a spectral type of sdO. [7] The best fit model for this star gives an effective temperature of 100 kK, with 5,250 times the luminosity of the Sun [5] and 60.5% of the Sun's mass. [6]

The main purpose of Space Shuttle Mission 2007 is to allow the gamer to experience real historical NASA Space Shuttle missions from liftoff (T-00:01:50:00) to landing. . Initially, Space Shuttle Mission 2007 was released with a set of 11 missions but as time passed, the development team has been releasing new missions as free
