The Submillimeter Wave Astronomy Satellite (SWAS), a NASA space mission, was dedicated to exploring the universe in the submillimeter wavelength range, a relatively uncharted territory in astronomical observations. Launched in 1998, SWAS was designed to observe molecular clouds and star-forming regions to better understand the processes of star birth.
SWAS was equipped with a high-frequency receiver capable of detecting submillimeter radiation from specific molecules, such as water, carbon monoxide, and molecular oxygen. These observations were critical for gaining insights into the composition and conditions within interstellar clouds where new stars and planetary systems form.
The mission's scientific objectives included studying the role of various molecules in the star formation process and investigating the chemical composition of space. SWAS contributed to our understanding of the complex interstellar medium and its role in shaping the cosmos.
