Microwave Instrument for the Rosetta Orbiter (MIRO)

NSSDCA ID: 2004-006A-04

Mission Name: Rosetta
Principal Investigator:Dr. Samuel Gulkis

Description

The Microwave Instrument for the Rosetta Orbiter (MIRO) is a microwave spectrometer designed with the following scientific objectives: 1) measure absolute abundance's of major volatile species; 2) characterize the fundamental isotope ratios, 3) quantify the surface outgassing rate; 4) measure the nucleus subsurface temperature and kinetic velocity; 5) measure subsurface temperature of asteroid targets; and 6) search for low levels of gas in the asteroid environment. MIRO is a dual-frequency, heterodyne receiver which can operate simultaneously as both a continuum and very high spectral resolution line receiver. The center band frequencies are 236 GHz (1.3 mm) and 562 GHz (0.5 mm). MIRO is pretuned to observe 8 transitions of 4 molecules including water, carbon monoxide, ammonia and methanol.
