Sea Launching

Just in time for last week launch of the DirectTV-11 satellite, MajorTom and his team have released their first version of a long overdue Sea Launch addon for Orbiter. I have been playing a bit with it and enjoying it. The launch platform could use more detailing (it's planned for next release), but the automatic guidance works well in both delivering the payload to a parking orbit then boosting it (thanks to its 3rd stage Block DM-SL) into a Geosynchronous orbit. Haven't been follow much before the Zenit-3SL launches, I had in mind that the 3rd stage was used to insert the payload into its definitive orbit, but in fact it is not the case since the payload is inserted into a elliptical orbit with an apogee at Geosynchronous altitude and a low perigee (<200km) . It is then up to the satellite to raise its perigee over the course of several burns.

Online research papers are a good resource of information. You can sit at your research paper writing for hrs, and still be unhappy with it. This is when you will want a refreshing search on your matter. On-line analysis by procustomwriting.com provides this search. They can also fill in some blanks that you have if you didn't display up in your course routinely. But remember to be truthful adequate and don't hand in these research paper writings as a solution of your own brain exercise.
