The mission of the Argos Alliance is disseminating useful information about Argos, a unique, satellite-based global data collection and tracking system vital to safeguarding earth’s environment, human safety, and the sustainable ecosystems upon which our nation – and humankind – rely.

Alliance History, Answering a Challenge

In February 2016, The Woods Hole Group, Inc. (formerly CLS America, Inc.) created the Argos Alliance to secure funding and support for the launch of Argos satellites. Argos budget requests in FY18 and FY19 were close to zero. The Alliance helped secured over $65 million to support upcoming satellite launches.
