Delta-v from Lagrange points to lunar surface?

Click For Summary

Discussion Overview

The discussion centers on the delta-v requirements for traveling from the Earth-Moon Lagrange points to the lunar surface. Participants explore the calculation methods and software tools that could assist in visualizing and determining these delta-v values.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the delta-v requirements from each Earth-Moon Lagrange point to the lunar surface and seeks software recommendations for visualization and calculation.
  • Another participant asks about the research done so far and what findings have been made regarding delta-v calculations.
  • A participant mentions finding delta-v maps but notes that they do not include Lagrange points, expressing confusion about how to calculate delta-v from these points since they are not orbits.
  • There is a suggestion that Kerbal Space Program does not model Lagrange points, which is confirmed by another participant.
  • One participant finds delta-v maps online that include Lagrange points and references "projectrho" as a resource for delta-v maps useful for mission planning.
  • A later reply indicates that Kerbal can model Lagrange points if the Principia mod is added.

Areas of Agreement / Disagreement

Participants express uncertainty about the availability of delta-v maps that include Lagrange points and the methods for calculating delta-v from these points. There is no consensus on the best approach or software for this task.

Contextual Notes

Participants note limitations in existing delta-v maps and the challenge of calculating delta-v from Lagrange points, highlighting the distinction between orbits and Lagrange points.

Who May Find This Useful

This discussion may be useful for individuals interested in astrodynamics, mission planning, and simulation software related to space travel, particularly those exploring the dynamics of Lagrange points.

TL;DR
What is the delta-v requirements from each of the Earth-Moon lagrange points to landing on the lunar surface?
What is the delta-v requirements from each of the Earth-Moon lagrange points to landing on the lunar surface?

What would be the best software I could use to visualise and calculate that kind of thing?

Thanks.

What research have you done on this so far? What have you found?
 
I have found delta-v maps but none of them include Lagrange points.
I have no idea how to calculate it. Any calculations I see are for orbits, which a lagrange point is not an orbit right?
I'm not sure if (or which) simulators include lagrange points either.
I will try Kerbal I guess..

I am happy to work it out I just don't know where to start.
 
Ah Kerbal doesn't model for Lagrange points :frown:

If I put your subject line "Delta-v from Lagrange points to lunar surface?" into google I get this which has many delta-v maps that includes Lagrange points.

You might see "projectrho" popping up a lot in that search, that is the "Atomic Rockets" resource for SciFi writers and game designers who wants to get the science right. There is a ton of good stuff in there, for instance the collection of delta-v maps for mission planning.

It does if you add the Principia mod.
