Default Station-keeping at more Lagrange points

This is a direct continuation of Station-keeping at Earth-Moon L2 scenario example

Attached is a .zip file containing six station-keeping at Lagrange point scenarios. These scenarios are:

1. Earth-Moon L1

2. Earth-Moon L2 (already posted in the earlier thread but included again here for completeness).

3. Sun-Earth L1

4. Sun-Earth L2

5. Sun-Mars L2

6. Sun-Vesta L2

These scenarios are intended to demonstrate active station-keeping at a Lagrange point. In all of these scenarios, there are two stock Delta-Gliders docked to each other at the Lagrange point. The motion of one of the Delta-Gliders ('GL-NT') is 'slaved' to that Lagrange point and will remain firmly anchored to it even at high time acceleration. The motion of the other Delta-Glider ('GL-01') is unconstrained and can be manoeuvred at will. It will not, however, remain at theLagrange point without active station-keeping and over time will drift away due to the inherent instability of Lagrange point orbits.

To run these scenarios, download the attached .zip file and, in the usual way, copy the files into the relevant Orbiter directories. To run these scenarios, do the following:

Earth-Moon L1
Open Orbiter and run the 'EML1.scn' scenario. Then, open the Lua Console and enter:

Code:
%run 'Lissajous/EML1'
The 'GL-NT' Delta-Glider will now be locked to the Earth-Moon L1 Lagrange point.


Earth-Moon L2
Open Orbiter and run the 'EML2.scn' scenario. Then, open the Lua Console and enter:

Code:
%run 'Lissajous/EML2'
The 'GL-NT' Delta-Glider will now be locked to the Earth-Moon L2 Lagrange point.


Sun-Earth L1
Open Orbiter and run the 'SEL1.scn' scenario. Then, open the Lua Console and enter:

Code:
%run 'Lissajous/SEL1'
The 'GL-NT' Delta-Glider will now be locked to the Sun-Earth L1 Lagrange point.


Sun-Earth L2
Open Orbiter and run the 'SEL2.scn' scenario. Then, open the Lua Console and enter:

Code:
%run 'Lissajous/SEL2'
The 'GL-NT' Delta-Glider will now be locked to the Sun-Earth L2 Lagrange point.


Sun-Mars L2
Open Orbiter and run the 'SML2.scn' scenario. Then, open the Lua Console and enter:

Code:
%run 'Lissajous/SML2'
The 'GL-NT' Delta-Glider will now be locked to the Sun-Mars L2 Lagrange point.


Sun-Vesta L2
Open Orbiter and run the 'SVL2.scn' scenario. Then, open the Lua Console and enter:

Code:
%run 'Lissajous/SVL2'
The 'GL-NT' Delta-Glider will now be locked to the Sun-Vesta L2 Lagrange point.


[Aside: These scenarios are a prelude to a more comprehensive treatment of station-keeping at general Lissajous orbits (e.g., Lyapunov and Halo orbits). These specific Lagrange points have been included as example here to demonstrate station keeping. For Lagrange points orbits of other systems - e.g. Jupiter-Callisto; Sun-Venus - I will need to work up the relevant datasets and, upon request, I'm happy to do that.]
