Abstract
Debris disks are short-lived belts of dust and debris formed from the collisions of planetessimals. These disks can be observed by their thermal emission in the mid/far-IR and sub-mm. Recently surveys with Spitzer's MIPS instrument have been greatly increasing our knowledge of debris disk incidence and properties. This contribution will describe forthcoming large (~500 systems) surveys of nearby stars at longer wavelengths using SCUBA-2 on the JCMT, and PACS+SPIRE on Herschel. Longer wavelengths give improved sensitivity to cool disks like our Kuiper Belt, and probe larger dust grains. In particular I will present the SCUBA-2 Unbiassed Nearby Stars Survey (SUNSS), and the DEBRIS Herschel Key Project, both of which target A-M type main sequence stars.
