Slide5Mission Phases during Proximity Operations
The proximity operations phase involves performing a set of hyperbolic flyby arcs to
characterise
the
Didymos
system and operate the payloads.See the talks by :HERA Approach and Arrival at Didymos: Mission Design and Timeline (T. Hormigo)
HERA close proximity trajectories and constraints (A. Pellacani)
ECP: Early Characterization Phase (ECP)
First assessment of the binary’s orbit and dynamical behaviour. Detailed Characterization Phases (DCP1, DCP2, DCP3)
To perform a detailed characterization and to build a landmark database to navigate the S/C.
New version (v0.5.0) of the study Hera SPICE Kernel Dataset has been released.
Slide6Early Characterization Phase (ECP)
See the talk by (A.
Pellacani
, GMV)
Slide7Detailed Characterization Phases
DCP1
DCP3
Slide8Operations plan
Teleconf
on 06/09/2019 on first draft of the operations plan
Discussion on distances and phase angles.
Next steps
Update operational constraints (HGA orientation, downlink periods, etc.) & Verify/update Instrument requirements Verify close-proximity trajectories compatibility with the required mission measurements Iteration of trajectory vs. requirements if neededSee the talk :Planning and Operation of Hera/AFC (J. Deller)
