EUCLID v.230630
Add-on for Orbiter2016

REQUIREMENTS
Launch scenario requires:
Falcon9 for Orbiter2016
https://www.orbiter-forum.com/resources/falcon9-for-orbiter2016.291/

RECOMMENDED
LagrangeMFD
https://www.orbiter-forum.com/resources/lagrangemfd-1-5-for-orbiter-2016.2868/
InterplanetaryMFD
https://www.orbiter-forum.com/resources/interplanetary-mfd.5500/


INSTALLATION
Extract all files to the root of your Orbiter2016 program directory, preserving the directory structure. This should NOT overwrite anything in the standard Orbiter package.


WHAT'S IN THIS ADD-ON?
The Euclid spacecraft, launch scenario for 01 July 2023.


MISSION
ESA mission to study dark matter and dark energy. Lissajous orbit around Sun-Earth L2.

LAUNCH SCENARIO NOTES
Launch inclination 35deg is my best guess based on available info.
After parking orbit insertion, a short coast (around 3-4 mins?) before making a 3200m/s prograde burn using IMFD Course "Delta Velocity" and IMFD Map "Plan". Set 3200m/s dV and tweak burn start time for good result on IMFD Map.
Trim velocity after Euclid separation using LagrangeMFD.


ADD-ON SPACECRAFT INFO
I have not attempted to model the real-life RCS configuration! A simple balanced rotation RCS is available.
Main engine is 2 x 10N thrusters, thrust in +Z (forward) direction (also linked to RCS Linear Forward control).
Momentum wheel attitude control is available [Shift + NumPad]

Controls:
G = Deploy Antenna
Shift+NumPad = Momentum Wheel rotation control
Shift+NumPad5 = Momentum Wheel Kill-Rotation

Data:
Empty Mass                                   2020kg
RCS Propellant Mass (Hydrazine)  140kg
Main Engine Thrust      	      20N (2 x 10N RCS)
RCS Engine Thrust                           10N 
RCS Engine ISP                            2300Ns/kg
