Hmm, cannot unlock first tech. Science reading shows that i am have needed 4 points (collected through 2 launches), but when trying to unlock - not enough points message. Third launch does not fixed it (nothing to collect). Trying to understand what goes wrong, for now.

Very usefull, thanks.

For real solar system there is a programm named "Trajectory Optimization Tool",that was created for Orbiter, it also allows multiple bodies in one flight calculations. It is maybe not the best one, i was just used it few years ago. Also there is other tools, like that, on orbithangar.com site. http://www.orbithangar.com/searchid.php?ID=5418

Maybe select stage as a whole, while shift or ctrl holded when left clicking on them ?

Jebediah removed from last version, with some other names, that are part of some trademarks, celebrity names, and other confusing words.

Talking about other challenge. Maybe it have a point to add that list of rules- 1) Turbojets only. 2) Only MechJeb mod allowed. (For automation of long flights). 2) Full thrust all the way. (Thats all about this - around the world as fast as possible in AERO - way) 2) Not higher than 20 km (Just to avoid going suborbital, if you go up to 25, but without going ballistic, nobody will complain).

Talking about micro meteorites protection. Going to a Mars in a weeks, means prolonged thrust burn time of engines. Lets cut max Gs to a 1, for a safety reason. Not sure, but t looks, like about 2 weeks of accelerating, and then, again, 2 weeks of braking. (i will check numbers later, maybe ). Point is, that we will need micro-meteorites defense, on braking stage too. Well, we can use engines as shield. But how? Our engines are essential part of a craft, - we must be sure, that our engines must be protected enough to withstand and continue to operate after impacts. So, conception of few weeks Mars travel, seemed little to overoptimistic in some overseen future. Concept of, for example, 6 month`s traveling, looks more reliable in the next 50 years.

It seems Bi-elliptical to me.

Relatively new theory about Venus, says, that Venus spin goes faster, not stopping. Thats because of tornado like atmosphere movement around its surface gives it a torque, and that atmosphere spin is caused by solar wind. Its actually quite interesting and exciting.

I am little bit aware to use mods, if i am absolutely not forced to use them (like mechJeb for controlled detachable parts, or fixed camera - to fly space-planes). Its not proved that i can not survive in game, without Nova punch mod, and i am sure as hell, that that 200 parts mod, will kill my notebook, so ... (there is goes lot of censored words). I can survive without this.

When life gives your lemons... You shit is full of lemon acid.

Yep, that was done before a lot of times. Even with a restriction of do not get higher than 10 km. Somebody even do that using infinite glide glitch (that is extra long way to do it). But, still, you are doing good. I can suppose that there is one thing that was not done before. - Around the world trip with only turbo engines on FULL thrust !!! My theoreticall assumptions that this is possible, and travel time might be something around 4 hours. Good luck !

Reentry heat is important, but that task is comparatively easer, than the ultimate goal, - applying different level of heat on different surfaces depending on their attitude. Actually, looks like the reentry heat mechanics should be extremely simplified, and parts should consist of few meshes (ie - low, upper, front) to be able use that simplified algorithm to each mech separately. Even for that, we need DPI - dynamic pressure variable to be in the game simulation. That all looks like massive rework of game engine needed. Hope i am wrong.

I learned today, that meters/second can be transferred in kilometers/hour, just by multiplying m/s number by 3.6. I.E.: 100m/s is a 100*3,6= 360 km/h. Strange that i did not know this before.

Well, maybe something close to that possible with additional huge gravity field from the side of periapsis. There is no way for such a system to be stable however.
