:hesaid:Ya, what he said. lol. Since you can put in your own custom elements, you could theoretically figure an optimal correction burn (and time of mcc), but doing two separate burns completely defeats the purpose of the program, and that is to calculate the best trajectory that doesn't...

Possibly, it is definitely something I would like to implement, but as of yet, I haven't looked at the math required for it.

Yes I have, but I had much of the same grievances as everybody else seems to have had. I also wanted to make something that could give you more information that is orbiter specific such as the outward, prograde, and plane-change values needed for transX, and also something that could display...

I've updated the scenario files, hopefully this should fix the problem.

The latest version of the Chapman probes (v3.0) is out, and I'll have the next Chapman Challenge up tomorrow. Great job people! flytandem, those transX plans are amazing! Especially that last one, it by far beats my most efficient Trojan trajectory (about 940m/s).

    Named after John Herbert Chapman, the founder of Canada's space program.     These probes were designed as fictional, but realistic spacecraft that could be launched aboard modern day rockets.  They are tailored towards Orbiter ensuthiasts like myself who wish to plan and design...

I'm a security guard on the night shift, so needless to say, I get a lot of free time to do stuff like this.

I thought I'd give everybody a little preview of a program I'm working on that creates "pork-chop" plots for figuring out optimal trajectories. It's come along pretty good, and I feel I've finished all the hard stuff. When it's finished, it will also display "Prograde" "Outward vel." and...

The key to slings such as these, is the time and date you do the swing-by of Jupiter. Ultimately you are trying to get your "longitude of the ascending node" (LAN), to match your target's LAN. From a mathematical point of view, the best fly-by date of Jupiter is when Jupiter's "True Anomaly"...

Ya, whenever I see anything written in the Epoch Times, I usually just shake my head, and turn away, it's pretty much garbage. It has about as much credibility (and objectivity) as the "National Enquirer". They even once posted a positive review for Ben Stein's creationist movie "No...

Maybe he was hired by Bill gates ;)

I just wanted to give a quick update on the next Chapman challenge. I'm still working on the next version of the Chapman probes, which will have corrected weights (looking at other spacecraft, they were still on the light side), and two new versions propelled by Hall effect thrusters, with a...

Flytandem, for the MPC Database Viewer/Exporter, try installing these: Visual Basic Run-time files

I was working on my upcoming Chapman-Ion (which I should probably rename, since it technically uses a Hall Thruster, not a Ion Thruster), and orbiting Ida's moon Dactyl (at only 100 meters) when I noticed my own shadow on the surface.

Sorry, but I don't want people using a stock Deltaglider, since it isn't just about dV. Using a Deltaglider would take away the difficulty of launching with a real-world launcher, and the deltaglider has much different thrust characteristics then a Chapman probe. When you unzip the files for...

Last chance for anyone still working on either of the challenges, if there isn't anybody still working on them, I'll began the third challenge.

No, they are exactly the same meshes and textures. Do you know what was your fps before?

Yet again, excellent work! I have to say, I love seeing people complete these challenges, it's nice to know that I'm not the only person who can do this stuff. By the way, is there anybody else still working on any of the current challenges? If there isn't, I'll bring this one to a close at...

Oooooh. :speakcool: I know I'd love to work on something like this, at the very least doing them just for fun. I have to say I like their first challenge of going to 2001 TW229 (a retrograde asteroid). I think I'm going to try and find a good solution for that one, maybe even find something...

Sorry, I didn't realize that those were from orbit, even better!
