GIFTS
GIFTS (Geostationary Imaging Fourier Transform Spectrometer) was to have been an experimental remote-sensing satellite that used an advanced instrument called an Imaging Fourier Transform Spectrometer to observe atmospheric temperature, water vapor content and distribution, and the concentration of certain other atmospheric gases present at a given altitude over time. By noting changes in temperature, water vapor, and gases that modulate energy in different regions of the electromagnetic spectrum, scientists would get an accurate picture of what is happening in the atmosphere and what weather is likely to develop. Part of NASA's New Millennium Program (NMP), GIFTS was mainly intended to space-validate cutting-edge technologies for future use; however, the project ended with the cancellation of the cancellation of NMP in 2008.
