The program, officially named "Hubble Deep Fields Initiative 2012", is aimed to advance the knowledge of early [[galaxy formation]] by studying high-redshift galaxies in [[Deep field|blank fields]] with the help of [[gravitational lensing]] to see the "faintest galaxies in the distant universe".<ref name="SWGreport">{{cite web |url=http://www.stsci.edu/hst/campaigns/frontier-fields/documents/HDFI_SWGReport2012.pdf |title=Hubble Deep Fields Initiative 2012 Science Working Group Report |work=STScI.edu |date=2012 |access-date=June 29, 2015 |archive-date=July 15, 2022 |archive-url=https://web.archive.org/web/20220715150044/https://www.stsci.edu/hst |url-status=live }}</ref> The Frontier Fields web page describes the goals of the program being:

* to reveal hitherto inaccessible populations of z = 5–10 galaxies that are ten to fifty times fainter intrinsically than any presently known
* to solidify our understanding of the stellar masses and star formation histories of sub-L* galaxies at the earliest times
* to provide the first statistically meaningful morphological characterization of star forming galaxies at z > 5
* to find z > 8 galaxies stretched out enough by cluster lensing to discern internal structure and/or magnified enough by cluster lensing for spectroscopic follow-up.<ref>{{cite web |url=http://www.stsci.edu/hst/campaigns/frontier-fields |title=Hubble Space Telescope: Frontier Fields |work=STScI.edu |access-date=October 4, 2013 |archive-date=July 15, 2022 |archive-url=https://web.archive.org/web/20220715150048/https://www.stsci.edu/hst |url-status=live }}</ref>
