It is one of the first realistic spacecraft simulations available for home systems. Space Shuttle was adapted to the Atari 8-bit computers and Atari 5200 by Bob Henderson (1984), then ported to the ZX Spectrum (1984), Commodore 64 (1984), Amstrad CPC (1986), and MSX (1986).

- G-type star (Wikipedia)
G-type stars, including the Sun, have prominent spectral lines H and K of Ca II, which are most pronounced at G2. They have even weaker hydrogen lines than F, but along with the ionized metals, they have neutral metals. There is a prominent spike in the G band of CN molecules. Class G main-sequence stars make up about 7.5%, nearly one in thirteen, of the main-sequence stars in the solar neighborhood. There are 21 G-type stars within 10pc.
