Science has a steep yet short learning curve. See here http://wiki.kerbalspaceprogram.com/wiki/Science for the particulars on how many times you can "do" science with each type of experiment and in which location and what their base points are, etc... If you want the cheat sheet for the biomes, search google images for "Minmus Biomes", that will show you a map of the Biomes on Minmus Now, in a recent mission, I came back with 1748 science, on a trip to Minmus. What I did is create a lander with lots of science pods on it: Example at the end of this post Then I chose Minmus because of its MANY biomes and low gravity which means it would be easy to jump around and land in each biome and do the following science ONCE PER SCIENCE DEVICE in each biome (unless you have the science lab, but that comes later). 1. Do a crew report (Transmit as this is a no loss science) 2. Do an EVA report (Transmit as this is a no loss science) 3. Get a surface Sample (KEEP!!! its 140'ish science each time) 4. Do a Science Jr. experiment (KEEP, once its used, go to the next biome and use a new science jr, you should have more than 1) 5. Do a Goo experiment (KEEP, once its used, go to the next biome and use a new goo, you should have more than 1) 6. etc... (if more science devices, continue the list) MOST IMPORTANTLY - If you want to get full science points, bring your ship (or experiment results) back to Kerbin and dont transmit any science that has a percentage less than %100. By the way, when you're landing back on Kerbin, how about doing temperature and barometer, and EVA report, and surface sample (yes, even if you land in the water, do a surface sample), and a science jr, and a goo. All that adds to yet more science and each time you land back on Kerbin, if you have any left over science jr or goo, you can do it. Granted, if you land in the same biome, there are diminishing returns. Its very possible to just about (or maybe actually) fill the science tree without going outside Kerbin-Mun-Minmus... I say just about, because I've not done it, I went to other planets. Anyways, I'm not sure if this explains it like you are 5 because I think you know more than you think you do. You just didn't have the particulars. Hope this helps Zach Note: As you can see in my picture, I had 6 Science Jr.'s, 1 for each biome I was going to land in on Minmus, I brought the entire craft back to Kerbin. I only made it to 4 biomes due to fuel issues. Only 1 was wasted because when I landed back on Kerbin, I used a Goo and a Science Jr.... why not right? Yes, there are 8 goo containers... symmetry
