Re: Orbital Mechanics

For GW Johnson re #200

Thanks for taking a look at the site.  Someone(s) put a lot of effort into that. As near as I can tell from a preliminary look, it uses JavaScript for the on-browser performance, which explains how the system could perform so well.

I found a page of documentation, and will attempt to make it available here In a form that our members might be able to use.  I am a very long way from being able to deliver anything like that, but it is good to have an example to study.

Regarding the Starship landing. Thanks for the detailed analysis and prediction that the Starship ** has ** to lay itself on it's side, to survive the landing. The scenarios you've painted look reasonable to my eye, and at first reading. Hopefully SpaceX will have cameras at the landing site as they did last time, so the behavior of a stainless steel cylinder rotating to horizontal while embedded a short distance in water will be interesting to see.

I made a screenshot and saved it on Dropbox.

You can download the image and (hopefully) print it.

I seem to have the program running, with these setups:

1) I put the letter "a" in the box for "enter orbit name" ( I think this can be anything but that's just a guess.
2) I clicked on the add launch button and chose Kennedy Space Center from the drop down list
3) There is a red "fire" button at the bottom of the page. I clicked that and it turned to "firing"
4) I changed the time value at the top of the page to x100, so now the simulation is running 100 times faster than real time (or at least I ** think ** so)

In any case, the default orbit is heading west, and right now the space  craft is over the Suez Canal.

I sure hope there is someone else in the NewMars community who is interested in trying this and can make better informed choices.

I am guessing this Orbital Mechanics Simulation web site may be a subtle advertisement for the capabilities of the team.

The multiple listings via Google seem to indicate this is a relatively small company, with 12 employees.
