only different. Southern hemisphere of Mars is something like six kilometres higher in elevation than the northern half. The Electric Universe people have a lot to say about such things - none of which involve impact events: hexagonal craters? Craters within craters? Crater chains?
"If schools are just doing the same old thing with iPads, or drinking the snake-oil-salesmen-turned-courseware-vendor Kool Aid, don't blame the tools." This is the problem. From what I have experienced working in a K-14 district for nine years, those teaching computer classes have a weak understanding of the technology; even less enthusiasm for the topic.
All based on the possibly flawed assumption comets are composed of slushy ice and rocky dusty bits. The good folks at Thunderbolts.info have for years been gathering information which suggests cometary bodies are dry rocky objects. http://www.youtube.com/watch?v=34wtt2EUToo&list=PLwOAYhBuU3UfvhvcT1lZA6KbSdh0K2EpH&index=3
Heat is required to make the moisture to make the ice. Cold air does not hold as much water. Cooling the planet will not bring on the glaciers.
Just freeze the astronauts solid; let them thaw out on the way to Mars. Separately launch life support for later rendezvous.
At least it appears DDG is trying to help with privacy. They have links on their minimalist home page which lead to suggestions for protecting your search privacy. Found out about Disconnect.me through DDG. DDG also has way cool swag [http://help.dukgo.com/customer/portal/articles/216375-t-shirts-stickers-more] on the cheap.
Teachers love this stuff. Students log into teacher-proof lesson plans. Some assignments can be automatically graded and submitted to the online grading system. School districts enjoy showing off all the wonderful technology they have implemented under the guise of "Look what we are doing for your children". The hidden truth is district administrators often have no idea how this tech works. Teachers rarely have an opportunity to be fully trained on the effective use of this tech (some don't want to learn). The end result is these iPads often get used as educational soothers to keep students quiet and in their seats.

Was less gravity *insert wild speculations why* in the days of the dinosaurs required for some of these creatures to attain their enormous sizes - like a brachiosaurus http://en.wikipedia.org/wiki/Brachiosaurus_altithorax
Will you be exploring anything along the lines of the Hutchison effects (http://www.rexresearch.com/hutchisn/hutchisn.htm) - and other other odd phenomena? Or are you just sticking to lightning?
Apple hasn't had tech friendly desktop hardware in over a decade. School districts buy desktops in bulk. It's nice when the hardware can stack - (not counting laptops). It's cheaper if common tools can repair desktops; not suction cups and Torx drivers. Techs I work with whine if anything more than a phillips driver is needed. I feel Apple is forgetting the creative professional market and the educational.
That nutty S on LEGO drives me up the wall.
