The astronomy research with the cornell infrared imaging spectrograph (arcoiris), will be relocated to soar during the 2018 calendar year. Depending on demand, arcoiris may be scheduled on blanco early in 2018a before being taken out of service to carry opto-mechanical modifications inside the dewar.
The faint object spectrograph (fos) was exchanged with stis during the second servicing mission and brought back to earth. A spectrograph spreads out the light gathered by a telescope so that it can be analysed to determine such properties of celestial objects as chemical composition and abundances, temperature, radial velocity, rotational.
Infrared spectroscopy (ir) relies on the fact that most molecules absorb light in the infrared region of the electromagnetic spectrum, converting it to molecular.

During the in-orbit checkout phase of the infrared spectrograph on board the spitzer telescope, it was found that the noise of the spectrograph's arrays was correlated with the number of cosmic ray hits. Our analysis reveals that the cause of that effect is most likely due to the algorithms used to correct cosmic ray hits on dark pixels.
