26702 - ODIN

ODIN is a Swedish dual disciplinary (astrophysics and atmospheric science) spacecraft that was launched by a START 1 rocket from Svobodny cosmodrome in far-eastern Siberia at 08:48 UT on 2001 Feb 20. (START 1 is a modified Topol ICBM.) The 250-kg, 340-W spacecraft has a pointing accuracy of 15 arcsec and a data storage capacity of 100 MB. It carries a cryogenic radiometer to monitor three millimeter-bands at 118.25-119.25, 486.1-503.9, and 541.0-580.4 GHz, at a resolution of 0.1-1.0 MHz. It also carries a cryogenic optical spectrometer to cover three visible and infrared bands at 280-800 nm, and another infrared band at 1,270 nm. The target gases of astrophysical interest are carbon iodide (CI), water vapor, hydrogen sulfide, ammonia, and a few others. For atmospheric studies, the gases are chlorine monoxide, nitrous oxide, nitrogen dioxide, hydrogen peroxide, nitrous oxide, nitric acid, and a few others. Both instruments were fed by a 1.1-meter Gregorian telescope. Initial orbital parameters were period 97.6 min, apogee/perigee 622 km, and inclination 97.83 deg.
