Example of analysis of Earth flyby during BepiColombo cruise mission.
On its journey to Mercury, the BepiColombo spacecraft made a close flyby of the Earth in April 2020. In this example we will represent its ground track above the Earth surface.

Get Bepi Colombo metakernel#
The BepiColombo mission is in operation since 2018 and its kernel set is already quite large and contains more than 400 versions:
BEPI_MK = ESA_MK['BEPICOLOMBO'] len(BEPI_MK.versions)
For the purpose of this example, we will use an old metakernel
generated in 2018 (
v200_20181212_002) that contains less
kernels than the current version. Feel, free to change this value
by latest to use the latest version. Here is the list of
the available metakernels for this version:
Download the kernels and load the trajectory#
tour = TourConfig( mk='plan', version='v200_20181212_002', kernels_dir='./data/BEPICOLOMBO/kernels', download_kernels=True, spacecraft='BEPICOLOMBO MPO', target='Earth', ) traj = tour['2020-04-10T00':'2020-04-10T06'] traj
