1. HST Observations to Detect Plumes/Outgassing from Europa

    Deadline: September 30, 2018

    The STScI Director has commissioned a committee to provide advice on optimizing future strategies for using Hubble to investigate potential outgassing from Europa. The committee is currently developing recommendations that will include suggestions for pilot observations in the near future. The full report will not be available until after the Cycle 25 proposal deadline (April 7, 2017). Consequently, interested
    parties should not submit proposals at this time unless the observations must be executed before October 27 2017. Time will be set aside for observations at later dates, and proposals related to the
    Europan plumes will be solicited as part of the first Cycle 25 Call for Mid-Cycle proposals, deadline September 30 2017.
