Over the last few years advances in observational technology and technique have made it possible to reach back in time and observe directly galaxies at high redshift, z>2 - i.e., at a time when galaxies were young. However, primarily for reasons of observational economy, most of the detailed studies of distant galaxies have focused on relatively luminous objects. We currently know very little about faint galaxies that in fact form the bulk of the population by sheer number and that indeed are responsible for forming most of the majority of stars and heavy chemical elements in the distant universe. This program will address this deficiency in our knowledge.

在过去的几年里，观测技术和技术的进步使我们有可能回到过去，直接观测高红移的星系，z>2 -即，当时星系还很年轻然而，主要出于观测经济的原因，大多数对遥远星系的详细研究都集中在相对明亮的物体上。 我们目前对微弱的星系知之甚少，这些星系实际上构成了绝对数量的大部分，并且确实负责形成遥远宇宙中的大多数恒星和重化学元素。 这个计划将解决我们知识的不足。
