Arthur Dodd Code (August 13, 1923 – March 11, 2009) was an astronomer who designed orbiting observatories.

[2] Arthur Code was born in Brooklyn, N.Y., and developed an early interest in astronomy when he was young.

[1] Code was one of the leaders of the OAO-2 project, an orbiting satellite that had light sensors, spectrometers, and various other radiation detectors.

Data from OAO-2 demonstrated that young stars were hotter than previously believed, and also showed the existence of ozone in Mars's atmosphere.

[1] OAO-2 continued to operate until 1973 and supported Dr. Code's contention, stating “a fully automated observatory like this is a good idea; we know it works.”[1] Code did a number of projects for NASA throughout the years, with himself claiming that he has been involved in "Space Astronomy" since the formation of the governmental space organization.
