location of pioneer 11 PAM upper stage can your trajectory tool handle FORTRAN ? :facepalm: The reason I ask is I am trying to gather some historical data on the locations of the solid upper stages for the voyager and pioneer projects...

may I order one of these with Delta IV CBC's with cross feed and a ACES stage in the carrier? :) ---------- Post added at 07:36 AM ---------- Previous post was at 07:30 AM ---------- its a super ET LEO fuel depot?:thumbup:

ok, sorry to hear that.So no utilizing the sun as the central body and then doing a satellite tour? what about the sun is the central body but the spacecraft is not leaving earth? let me go back read your " read me" PDF :)

not a problem! I have made a post in regards to a future...................flight the thread idea is in the above post, your read me PDF suggests replacing the sun with your planet of choice and using your tool to propagate satellite tours right? the post is over on the, "challenge" thread...

I was on the OPAG decadal survey site,found a reference to cassini extended tour astrodynamics planning papers, I found the authors name and goggled it, emailed his university addressed and asked him for a copy! our site says the PDF document is to large to post here. Arrowstar suggested I start...

using trajectory optimizing tools design our own Cassini end of mission tours! I have a PDF document with the above title, however its to large to up load here, this astrodynamics paper shows possible trajectory from Saturn orbit to Jupiter,Uranus and Neptune. I would like to design a flight to...

cassini paper

that's a good idea, let me create a thread for that, will I be able to input old orbital ephemeris into your trajectory tool? (and how) also notice you can change Sun to a planet for satellite orbital tours, I have a PDF document that everyone should read, CASSINI END-OF-LIFE ESCAPE...

I am lost, are there two threads on this topic? I am lost, are there two threads on this topic? and they are not merged?

my first post here! Arrowstar, what you are doing is wonderful! thank you.I will see if its possible to teach my self how to use this program, I have a project in mind.The pioneer and voyager space craft has Star solid motor kick stages, years ago I was talking to Dr Stone( Aug 1994) the Pioneer...
