Is the Delta 7920/25 capability allowed for MIDEX?
Yes, you may propose to use a Delta 7920 or other ELV, keeping in mind that the cost of the launch service must be included within the NASA cost cap of $140M. Because it is anticipated that most proposers will use an SELV or Med-Lite launch vehicle for MIDEX, those launch options are explicitly listed in the AO and Explorer Program Library. For costing and other information on the Delta 7920, or any ELV available through a NASA contract, consult with the points of contact listed in the Expendable Launch Vehicle Opportunities document in the Explorer Program Library.
