We describe the Faint Object infraRed CAmera for the SOFIA Telescope (FORCAST) which is presently operating as a facility instrument on the Stratospheric Observatory For Infrared Astronomy (SOFIA). FORCAST provides imaging and moderate resolution spe

HIRMES is a far-infrared spectrometer that was chosen as the third generation instrument for NASA's SOFIA airborne observatory. HIRMES promises background limited performance in four modes that cover the wavelength range between 25 and 122 $\mu$m. Th

We present new 37.7 micron far-infrared imaging of the infrared luminous (L_IR ~ 5.16x10^{11} L_sun) interacting galaxy Arp299 (= IC694 + NGC3690). We show that the 38 micron flux, like the 60 and 100 micron emission, traces the luminosity of star fo

We have imaged the bipolar planetary nebula M2-9 using SOFIA's FORCAST instrument in six wavelength bands between 6.6 and 37.1 $\mu m$. A bright central point source, unresolved with SOFIA's $\sim$ 4${''}$-to-5${''}$ beam, is seen at each wavelength,
