We present far-infrared images of the Galactic oxygen-rich supernova remnant(SNR) G292.0+1.8, acquired with the PACS and SPIRE instruments of the HerschelSpace Observatory. We find that the SNR shell is detected in the PACS blue (100micron) band, but not in the red (160 micron) band, broadly consistent withresults from AKARI observations. There is no discernible emission fromG292.0+1.8 in SPIRE imagery at 250, 350 and 500 micron. Comparing the 100micron emission to that observed with Spitzer, at 24 and 70 micron, we find avery similar appearance for G292.0+1.8 at all three wavelengths. The IRemission is dominated by dust from non-radiative circumstellar shocks. Inaddition, the radiatively shocked O-rich clump known as the 'Spur' on theeastern side of G292.0+1.8, is clearly detected in the PACS blueimages, withmarginal detection in the red. Fitting the existing 14-40 micron IRS spectra ofthe Spur together with photometric measurements from 70 micron MIPS and 100micron PACS photometry, we place an upper limit of <~ 0.04 solar masses, ofejecta dust mass in the Spur, under the most conservative assumption that theejecta dust has a temperature of 15 K. Modeling the dust continuum in the IRSspectra at four positions around the rim, we estimate postshock densitiesranging from n_p = 3.5 cm^-3 to 11 cm^-3. The integrated spectrum of the entireSNR, dominated by swept up circumstellar dust, can be fit with a two-componentdust model with a silicate component at 62 K and graphite component at 40 K fora total dust mass of 0.023 solar masses.
