DESCRIPTION:In the course of the past few decades\, gravitational lensing 
 has proven to be an exceptionally powerful tool for studies of faint objec
 ts at the edge of the observable Universe\, as well as for the characteris
 ation of the mass distributions in lensing systems. Generating significant
  gravitational amplification over areas of several square arcmin\, massive
  galaxy clusters in particular are natural telescopes that allow us to pro
 be the distant universe to unprecedented depth.\nRecognising the enormous 
 potential of the gravitational amplification provided by massive clusters 
 and capitalising on the results of all-sky surveys designed specifically t
 o find these rare systems\, STScI and SSC have dedicated 840 orbits and up
  to 1000 hours\, respectively\, of Director's Discretionary Time on the Hu
 bble and Spitzer Space Telescopes (HST and SST) to extremely deep observat
 ions of six carefully selected massive clusters and "blank" parallel field
 s. The HST images obtained by the Frontier Fields (FF) initiative reach a 
 limiting magnitude of 29 (AB) in each of six passbands covering the entire
  optical and NIR window (0.4-1.7 microns)\, complemented by 50-hour imagin
 g with SST in each of two passbands at longer infrared wavelengths (3-5 mi
 crons). \nThe primary science goal of the FF project is to probe  the po
 pulation of high-redshift galaxies to luminosity limits that are currently
  unattainable without gravitational magnification\; highly accurate mass m
 aps of the lensing clusters are both a byproduct of the observation and a 
 crucial prerequisite for their full scientific exploitation.  Additional 
 research facilitated by the FF initiative includes topics as diverse as ac
 celerated galaxy evolution in high-density environments and studies of tra
 nsient sources in both the cluster and blank flanking fields.\nThis IAU Fo
 cus Meeting aims to provide a stage for observers\, theorists\, and modele
 rs to present results from the FF project\, discuss new lens modeling tech
 niques\, and prepare and evaluate observational strategies to further expl
 oit the FF with both the James Webb Space Telescope and ground-based 30-m 
 class telescopes.
