NSSDCA ID: 1966-066A-06
Mission Name: Gemini 10The objective of the experiment was to obtain the spectra of the brighter stars from 2200 to 4000 A. A Maurer 70-mm camera with an ultraviolet lens having a 22-mm aperture, 73-mm focal length, and a field of 30 deg diameter was used. Each film magazine carried 50 frames of Kodak spectroscopic I-O emulsion on an Estar base. The grating produced spectra with a dispersion of 180 Angstroms per millimeter. On July 19, 1966, the astronauts opened the hatch and spent 40 minutes taking pictures. Twenty-two frames were exposed on the southern Milky Way from Crux to Vela. The Balmer Continuum is the only feature of the spectra which can be identified because of a loss in wavelength resolution. There are no plans for NSSDC to acquire these data.
