Notes
--------------------------------------------------------

   January 22, 2025 v0.0.3

      Added default attitude CKs for all study scenarios incorporating
      Ram pointing below 1000 km altitude and Sun pointing above 1000 km
      altitude with 15 minutes slews in between. For Sun pointing, roll
      angle around the Sun direction optimises the SPAM LoS alignment
      with the ecliptic and Nadir LoS not obstructed by SC for M-EAS.

      Updated SPAM alignment based on latest placement on +Z SC panel.

      Updated SOSPIM field-of-view aperture angle.


Issues fixed for this release
--------------------------------------------------------

   [SPICEPCR-1565] - Publish default CKs for all study scenarios.


Appendix: Release History
===========================================================================

   November 4, 2024 v0.0.2

      Added trajectories and meta-kernels for the following study scenarios:

       - mmatisse_study_2036_EEM_LD21_FDC_IPO1.tm
       - mmatisse_study_2036_EEM_LD21_FDC_IPO2.tm
       - mmatisse_study_2037_T2_LD21_DLC_IPO1.tm
       - mmatisse_study_2037_T2_LD21_DLC_IPO2.tm
       - mmatisse_study_2039_T2_LD21_DLC_IPO1.tm
       - mmatisse_study_2039_T2_LD21_DLC_IPO2.tm

      Extended aareadme descriptions of each scenario:

       - Launch year: 2036/2037 (nominal launch period) or
                      2038/2039 (backup launch period)
       - Transfer type: direct Earth-to-Mars transfer (short T2 or
                        long T4 transfer), or with an intermediate
                        Earth flyby, Earth-Earth-Mars (EEM) transfer
       - Launch day: from 1 to 21, LD1 = LPO, LD21 = LPC
       - Configuration: either father-daughter configuration (FDC)
                        or dual-launch configuration (FDC)
       - Initial parking orbit (IPO): for a given post-MOI
         inclination of 60 degrees, there are two hyperbola
         solutions (IPO1 and IPO2).

   June 20, 2024 v0.0.1

      Added preliminary versions of Instrument Kernels.

      Added default attitude CK based on altitude profile for
      RAM and Sun pointing modes.

   March 27, 2024 v0.0.0

      First draft of the SKD that includes basic frame definitions and ID
      assignments in order to be able to use the mission analysis
      trajectory data and visualize it with Cosmographia. This includes the
      following M-Matisse SPKs:

         henri_ipo1.bsp
         henri_ipo2.bsp
         marguerite_ipo1.bsp
         marguerite_ipo2.bsp
