A super quick google for "free alternative to matlab" yielded this site as the first hit... http://www.math.tu-berlin.de/~ehrhardt/matlab_alternatives.html I have not tried any of the links, and cannot guarantee that they are not all links to virus/trojan/spam filled pools of junk code.

Well, lesse here. Let's apply Kill Translation to an object "standing still" on the earth... For the sake of Humor, I'll include some lyrics from "The Meaning of Life." Since we're "standing on a planet that's evolving, revolving at 900 miles an hour..." Kill Trans would halt that, so...

Having not even had the opportunity to download the latest version, here is my thanks to you... :tiphat:

It was me, -begin dramatic reading... The launch day was sunny, with very little wind. The crew's hopes were high. We ascended to LEO and made for the MIR to refuel before the long TMI burn later the next day. Refuelling went perfectly, and the DG4 was primed with a three-man, two-woman crew...

Given the high Isp and high thrust of the Delta Glider, it is not possible using today's technology.

Details here.

To say "Just another new user" in this forum? I would understand if you were just another cog in the WoW machine - loggin on to the WoW forum to gripe/rant/expound/chortle about how your favorite class/raid/clan/ playstyle/server is over/under/nuclear powered and needs to be...

Just to be safe, I asked for some more screen shots. If it's either Orbiter or Celestia - repackaged, it will get reported as infringing material.

The idea is that the new version of Orbiter should work out of the box (pretty much) with the latest edition(s) of VC++ Express.

As reported in the previous post, Browse to your Orbiter directory. Go to the CONFIG folder located in the Orbiter Folder Go to the VESSELS folder located in Config Folder Find the vessels you wish to remove and delete them. They will no longer be available in the game, and won't show up in...

Here we go... Where, V=DeltaV and is known (you choose a DeltaV you require) I=Isp and is known (You choose an Isp you like) f=fuel mass (Solve for this) m=empty mass (When given this) For a given DeltaV and Isp you can determine the weight to fuel ratio as follows: V = I*ln(m/(m+f)) V/I =...

Personally, I use reference objects for my masses. If I have an interplanetary battleship that is about the size of the USS Liberty, then I might fudge a number for "space age materials" (say 65% of Liberty's dry mass) and throw in a bunch of fuel capacity. So, yea. Lots of research.

I think it would be a useful MFD. People use MFDs to automate their flights all the time. (IMFD / TransX anyone?) So, having an MFD / AP to align to a docking port would actually be pretty useful.

I think what ar81 is asking is, how do you estimate the mass of a vessel that is, say 100m in length by 20m wide. How do you estimate the mass of the life-support, navigation, control, and automation systems? How do you estimate the mass of the frame, empty fuel tanks (for a given fuel...

Another, more complicated, solution to establishing an orbit would be user configurable target settings. Use distance from body and Local xyz velocities. Then we could come up with a library of standard approaches for various major bodies. The next step might be to include this table of...
