Could someone please change the thread title? Everytime I see it pop up in the recent threads, I panic a little...

Here, try this: MPC Database Asteroid Viewer and Exporter v2.0.3 I had good results see for example: New Horizons Kuiper Belt Extended Mission

No, my point is what I said that my point is, that EIn has no real meaning until you are in an actual orbit. Now try launching to the correct heading and watch what happens to EIn along the way. It's to show that at no point in time leading up to the eject date will EIn reach zero while you...

For those of you thinking that EIn is the relevant criterion here, try to use the surface launch in either of these scenarios without altering the valid course plan: BEGIN_DESC Contains the latest simulation state. END_DESC BEGIN_ENVIRONMENT System Sol Date MJD 51983.5694361846 Help...

It has no purpose when OpMode=Course, hence dark green and not bright green. It is just a leftover of other modes that do use it. Optimizing the delta-v - for the whole trip or for the launch phase? If the former, don't forget that the Course program has a Tej, but anytime around 59064.5...

Poe's Law much? Look, it's a seascape of troops disembarking from ships. If there were palm trees or something, I could see the fuss, but as it is, we are all just taking someone's word for it. One could just as easily change the stamp to commemorate the 75th anniversary of the Allies landing...

Antares Manned Spacecraft 2.51 But for Orbiter2010.

Because Zippyshare is polluted with unusually aggressive adware.

So has anyone ever seen Bennu and Ryugu in the same place... at the same time? https://en.wikipedia.org/wiki/101955_Bennu https://en.wikipedia.org/wiki/162173_Ryugu

Could you please explain how PAYLOAD and BALLAST scenario parameters are being used to size the airship, or why PAYLOAD does not get added to the total mass? Also, I saw a condition in which the lifting gas had lower pressure than the atmosphere. That shouldn't happen on earth with a helium...

When your simulation respects actual physics, one solar system is plenty.

It's magnificent, but I think there are a few bugs that I need to check on if I get time...

I'm not sure if I understand your questions ("as long as masses to be correct"?). But I think that if you understand the sequence better, it will help you. In IMFD, this is how it goes, and I think that TransX is similar: On the ground you plan your interplanetary course. At this stage, you are...

Is this the first Pegasus launch since Orbital-ATK became Northrop-Grumman? What does the Stargazer look like these days?

Carrying capacity.

I'm not sure that I follow your plan, but I wan to add one point regarding multiple attached vessel stacks: JUst make sure that the vessel that ends up in orit is the one that starts outon the pad. IIRC, in old Velcro rockets, you launched from the bottom stage focus and ended up in the upper...

Hi Marjin, you might be interested in this: MPC Database Asteroid Viewer and Exporter v2.0.3

I think that there is a feature to auto-orient the ISS in this: PursuitMFD 2016 Also, IIRC, in Orbiter 2010 the UCGO ISS added an RCS makes the ISS a selectable vessel.

Perhaps I can help. Because Orbiter itself saves scenarios using state vectors, and ELEMENTS are only used for hand-made scenarios (and not many know how to do this)? Actually, no, not really. I recommend that you visit Celestrak for information. See this...
