The Cosmic Background Explorer revealed for the first time that, the extragalactic light at infrared wavelengths is comparable to that at optical wavelengths indicating that a large fraction of the activity in the Universe takes place in dust obscured areas. In this article I attempt a review of the cornerstone infrared missions that have revolutionised our view of the dusty cosmos. The focus is on advances in extragalactic astronomy and in particular the discoveries of galaxies whose bolometric luminosity is dominated by emission in the mid- and far-infrared wavelength regime. Alongside discoveries in the infrared domain I discuss advances in the sub-millimetre regime and stress the synergy between the two. The imminent launch of ESA's next infrared mission, the Herschel Space Observatory, offers many opportunities and I highlight some of the unique strengths of this mission. Finally, the availability of the ATACAMA Large Millimetre Array will push the frontiers of exploring the dusty Universe even further. These are certainly exciting times for infrared astronomy.
