KPL/MK Meta-kernel for HERA Dataset v171 -- Study Launch 2024 Earth-Mars-Asteroid 20241121_001 ============================================================================ This meta-kernel lists the HERA Study Launch 2024 Earth-Mars-Asteroid SPICE kernels that provide information for the Study Launch 2024 Earth-Mars-Asteroid scenario. - Launch on October, 7th 2024 - Hera study trajectory from launch to end of mission The kernels listed in this meta-kernel and the order in which they are listed are picked to provide the best data available and the most complete coverage for the HERA Study Launch 2024 Earth-Mars-Asteroid scenario. The scenario is based on the study OEM files provided by Mission Analysis. This meta-kernel was generated with the Auxiliary Data Conversion System version: ADCSng v4.3.7. Usage of the Meta-kernel --------------------------------------------------------------------------- This metakernel is only for science operations analysis at this stage. Note that a default Attitude profile has been implemented for the whole mission by the following C-Kernels: hera_sc_crema_2_1_LPO_241007_270303_f181203_v??.bc Reading the comments of the binary C-Kernels is very helpful to understand the implemented attitude. You can use the following NAIF command line utility to extract that information from the kernels: > commnt -r hera_sc_*.bc This file is used by the SPICE system as follows: programs that make use of this kernel must "load" the kernel normally during program initialization. Loading the kernel associates the data items with their names in a data structure called the "kernel pool". The SPICELIB routine FURNSH loads a kernel into the pool. The kernels listed below can be obtained from the ESA SPICE Web server: https://spiftp.esac.esa.int/data/SPICE/HERA/kernels/ or from the ESA SPICE FTP server: ftp://spiftp.esac.esa.int/data/SPICE/HERA/kernels/ Implementation Notes --------------------------------------------------------------------------- DISCLAIMER: Please note that the current kernels are pre-operational and they are subject to change. It is recommended that users make a local copy of this file and modify the value of the PATH_VALUES keyword to point to the actual location of the HERA SPICE data set's ``data'' directory on their system. Replacing ``/'' with ``\'' and converting line terminators to the format native to the user's system may also be required if this meta-kernel is to be used on a non-UNIX workstation. ------------------- This file was created on November 21, 2024 by Alfredo Escalante Lopez ESA/ESAC.
