1. Suggestion - Torque Visualiser

Hmm, what would be a good way to visualize torque. Or would you want to simply visualize forces causing torque (forces applied to a certain point on a craft)?
2. Current EDU Version?

Hello, Just here to tell you that KerbalEdu is now based on 1.2.2 (the latest version of KSP). Just released the update today.

4. KSP-EHC Mission I and II Force Arrows

Hello, Sorry for the late answer. I think the arrows the OP is talking about are the KerbalEdu force arrows (picture), not the vanilla aerodynamic indicators. I forgot to add them when updating the EHC missions for the latest version of KSP (1.1.3), so it is a bug. It will be fixed in the next version of KerbalEdu. In sandbox mode you can still use them however.

6. KSP EDU Energy Sphere values seem off

Now i also want to make this note about the energy spheres. If you set the "Reference frame:" to surface or launch altitude the kinetic energy sphere will use speed relative to surface for calculating the kinetic energy. This will give you "wrong" values in orbit and at great heights and might even make the energy sum seem to change. You should only use these options when at low altitudes and speeds where the craft can be considered to be moving along with the surface of the body.
7. KSP EDU Energy Sphere values seem off

Hello, Actually the whole formula for gravitational potential energy is , where K is an arbitrary constant that can be used to define where we consider the zero potential to be. Usually "pretty much everyone in physics" uses 0 for K meaning that gravitational potential energy will only be approaching zero at infinity (infinite distance from the main body), which makes sense since there is not limit to the reach for the force of gravity (it just gets weaker and weaker the longer the distance). It also makes calculations easier since you don't need to include the constant K everywhere. However for the purpose of visualizing how kinetic energy is converted to potential energy and back with the energy spheres we consider potential energy to be zero at the surface of the main body (K = GMm / R, where R is the radius of the main body). Otherwise we could not really draw a sphere to visualize it since it would always be negative for finite distances. I am actually now making changes to the energy spheres UI for the next update of KerbalEdu to add an option to set K = 0 (potential zero at infinity). It will make the potential energy sphere not show, but you will be able to demonstrate the values it gets when it is calculated the usual way.

Yes, KerbalEdu license gives access to all future versions of KerbalEdu. Updates to KerbalEdu are not done via the launcher though. You need to log in to kerbalspaceprogram.com store and download the new installer from there and reinstall to update. I don't know what's up with your teacher and version 0.22. If I remember correctly there never even was a KerbalEdu done based on that early a version of KSP.
9. Kerbal EDU

I'm afraid I don't have much of a further explanation at this time. I have just been happy that they allow us to make and sell the edu version and have not criticized them too much for putting DRM in it. KSP is Squad's game anyways, if they wish for the edu version to have DRM then DRM it shall have, however weird it is considering the base game doesn't have any. And it is not that oppressive a DRM anyways, all it does is compare your license key and mac address to those saved on the server to check that you are not exceeding the number of computers you are allowed to run it on. It does have its problems of course, for example when mac addresses change or users remove the installation without running the uninstaller so that the server doesn't know they've uninstalled, or when an overzealous firewall blocks it from connecting to the server, but they can usually be dealt with easily enough when the customer contacts us for support. That said, we are going to ask Squad if they could remove or at least change it for our upcoming 1.1 update for KerbalEdu.
10. Kerbal EDU

Required by Squad. In practice the way it goes is we get a build of KSP with the DRM in it from Squad and then put the edu features on top of that.
11. Kerbal EDU

DRM in KerbalEdu is not implemented by TeacherGaming or any other third party. It is required and has been implemented by Squad.
12. Update

Wrong! KerbalEdu will get all the updates normal KSP does. KerbalEdu also has full mod support and all the game modes normal KSP does. It only adds features, nothing is removed. It is also (maybe with the exception of some limited time sales) cheaper than regular KSP if you are buying it for a school or other educational institution.
13. New mods

Yes, mods work in KerbalEdu just as they do in regular KSP.
14. is it possible to create construction tasks in mission editor?

Yes, in the mission editor you can set up which parts are available in a mission. Go to the Mission Options tab, set Mode to "Science Sandbox" and add an EduTechConfig Scenario Module. In the options of the EduTechConfig you can add parts to a "Tech", and more "Tech"s. Techs are collections of parts that can be made available or unavailable via the mission events. The first tech starts as available in the beginning of the mission. There is currently no list of part names there, so I'm afraid you need to manually check the name of each part from their .cfg files.
15. Earth History Campaign

Hi, Sorry, but this is not currently possible for the KerbalEdu EHC missions. They should be short enough though that saving is not required that much.
16. My Planet Packs aren't working! :O

Which mods? Are they supposed to be compatible with Kerbal Space Program 1.0.4? Have you tried them separately, maybe they simply aren't compatible with each other?

18. KerbalEdu Earth History Campaign released

Hello, Here to inform you that a new mission has been released to Earth History Campaign. First update your version of KerbalEdu (download from https://kerbalspaceprogram.com/kspstore and install). Then go to http://www.kerbaledu.com/ehc, select mission V and play. Mission is divided into two parts that can be launched separately. Sorry for requiring you to update again. We were originally not planning to update the game between the missions, but we needed new conditions and actions to the mission editor to make the new mission as we had envisioned it. On the plus side you now also get to play with them and the new condition grouping functionality in the mission editor (log in at http://kerbaledu.com/kerbalmissionlibrary/ and select Mission Editor).
19. Mission III

Hi, It is a bug. I don't think he even actually dies anywhere, it is just a false message about it.
20. Earth History Campaign

Yes, it is possible to land on the runway. Your trajectory should take you quite near it. When you have entered atmosphere try to achieve level flight along the same trajectory you entered on. The runway should be somewhere to the front (maybe a little to either side) on a flat patch of land somewhere on the ocean shore. Quite close. Simply fly directly towards the marker and a tutorial window should pop up when you are near enough. It also pauses the game so you can't crash even if you approach at high speed. No need to land.
