Default Nasa Trajectory Browser unavailable

About two weeks ago I could use the Nasa Trajectory Browser without problems. I am using it to get delta-v values for various trips across the solar system.

Then, my browser threw warnings. The certficate was expired on october 2 2018 0:38:17. It's a free certificate from Let's encrypt.

Now, almost two weeks later, this great resource is still not available. What's going on? Are they not capable of replacing that certificate or someting? I am afraid this part of Nasa's public domain is subject to incapable it and this geat resource may be lost to us. Does somebody know an alternative?

No, but I may do so. Thing is, I do have the impression the tool isn't being maintained for a longer while now. It had dead links etc. so I don't expect them to calculate new trajectories for upcoming years and add them.

Also, they only have trajectories starting from earth. That's another reason why I am interested in alternatives.

Well, did you look into GMat already?

Thanks for the suggestions. I'll look into those.

I sent an email to nssc-contactcenter@nasa.gov. Not sure if that's the right point of contact, but let's wait and see.

Not yet. The math is -way- more complex than I thought. Also, I want to use it in a web app. So I am on the lookout for something which I could copy.

I am currently investigating the javascript math functions of this site: http://orbitsimulator.com/formulas/OrbitalElements.html

I think it's pretty close to what I am looking for.
