Interstellar travel calculator

I found this nice online javascript program:

Is it possible to integrate something like this into Celestia?

I mean

1.) mark a destination star or planet (automatic distance input)

2.) input spacecraft mass, acceleration, maximum speed, fuel energy conversion rate

3.) output fuel mass and traveling time.

Can it be done?

In principle a Lua function could do it, either as a CelX script or invoked by a ScriptedOrbit.

Do you know any similar script I can download?

The only slightly similar one I found is "Two Objects Relative Info" CELX. This script displays relative Distance, Latitude and Longitude, as well as speeds: Total, Radial, Transversal and Angular for any 2 objects.

Here's an external calculator written in javascript. Maybe someone could translate it into Lua.

Lol I meant similar CELX script. I want to reverse engineer a slightly similar one, it is quicker than starting from scratch...
