Network Organization
NOW is organized by 4 Co-Leads, and a Steering Committee made up of PIs from relevant Ocean Worlds projects funded through NASA R&A grants. More information about each member of the NOW steering committee, together with links to their research programs are listed below. All scientists and engineers funded as part of each project-team that has chosen to join the NOW Network are Members of the NOW Network.
In future, all ROSES proposers will be able to volunteer to join NOW by responding to a query during the proposal submission process.
In the spirit of inclusivity, NOW also offers the opportunity to join as an Affiliate of our network. Affiliates receive regular updates on NOW activities including alerts for new funding opportunities, details of how to participate in forthcoming community meetings and invitations to join our quarterly Ocean Worlds on-line seminar series. Affiliate status is designed to accommodate all those who are not currently funded through an active NASA Ocean Worlds research award but who seek to become involved in future Ocean Worlds research activities.
