Amendment 59: New Due Dates for Planetary Science Programs: C.3 SSW, C.8 LDAP, C.21 NECF, C.28 LSITP, C.29 Astrodynamics, and E.4 HW.

The proposal due dates for five Planetary Science program elements of ROSES-2018 were previously temporarily changed to "TBD" as a result of the partial government shutdown. This amendment releases new due dates for these program elements and extends the comment period for draft text for the sixth program element.

For C.21 the DRAFT Planetary Science Early Career Program (NECF), community comments on the draft text are now due February 14, 2019.

For C.28 Lunar Surface Instrument and Technology Payloads (LSITP), the Step-2 proposal due date is now February 27, 2019.

For C.29 Astrodynamics in Support of Icy Worlds Missions, Step-1 proposals are now due March 11, 2019 and Step-2 proposals are now due April 18, 2019. Moreover, the point of contact for the Mystic and MALTO Astrodynamics Tools in Table 1 has been changed.
