Abstract

EarthFinder is a Probe Mission concept selected for study by NASA for input\nto the 2020 astronomy decadal survey. This study is currently active and a\nfinal white paper report is due to NASA at the end of calendar 2018. We are\ntasked with evaluating the scientific rationale for obtaining precise radial\nvelocity (PRV) measurements in space, which is a two-part inquiry: What can be\ngained from going to space? What can't be done form the ground? These two\nquestions flow down to these specific tasks for our study - Identify the\nvelocity limit, if any, introduced from micro- and macro-telluric absorption in\nthe Earth's atmosphere; Evaluate the unique advantages that a space-based\nplatform provides to emable the identification and mitigation of stellar\nacitivity for multi-planet signal recovery.\n
