First Impressions:
I do have some mixed feelings about your site when I was going over it. You'll see what I mean when you keep reading through the rest of the review. I did experience some waiting time while to site was loading but I was expecting that since you mentioned that up front so I made sure to be patient. I did like the look of your site once it loaded for me. The rest I won't mention here because it'll be discussed in other parts of your review and I don't want to mention it twice. So I'll let you get on with your review...

Design Quality:
I couldn't find any grammar or spelling mistakes and that is very important. You'll see why that is important when you get down the "Business Sensibility". The first thing I would change is I would put the "About Me" on the beginning page of your site, rather than having it located in the navigation bar and people having to go looking for it. I think visitors would benefit to seeing it up front rather than having to seeking it out. The only other think I would change is making the font/text a little bigger in the navigation bar so it is a little bit easier to read. The "Curiosity Doc" wasn't working when I was viewing your site so you may want to take a look at that. Also, in the "Murry Buttes, the sound wasn't working for me at all. That's something else that may need looking into and fixing. All of this stuff is relatively minor and could probably just be some quick fix.

Site Structure:
It doesn't take much for me to make it from the first page to the main page of your site. I understand you wanting to make the site easy to use and I appreciate that. If there is one thing that drives me absolutely crazy, it's not being able to find my way around a site, regardless if it's a forum, blog or website. Finding the icon in the top right hand corner that opens up the navigation bar, so to speak, wasn't tough for me to accomplish. I'm glad to see that you can click on the icon to make the navigation bar appear or disappear, depending on what you needed and where you wanted to go. And I loved the "About Me" added to that navigation bar. It's descriptive, yet, it gets right to the point.
Good
Originality:
Your site is pretty unique. Out of all the reviews I've done and all the packages I've done since being a member of the staff here on FP, I've never come across a site like yours. Especially one that is as interactive as yours. I love the fact that I can click on "Mars" and get it to go in any direction that I want. That's pretty awesome. I also enjoyed watching the rover move around and being able to control it and move it to the different points...that was a very fun and educational experience (you would be directed to it in the "Curiosity Game" in the navigation bar).
Excellent
Business Sensibility:
I see your website as being a site for educational purposes, to help students learn when they are discussing the solar system at school. So, if it were me, I would try to market your site towards any type of school or educator. They would probably get the most use out of a site like yours to help teach their kids about that particular subject. I would fix the loading time on your site. While it's not terrible, it's not great either. From a business stand point, you'll have to fix the loading time and make it better if you are going to pitch your site to potential clients, regardless of who those clients are. If an educator is going to use your site in their classroom for learning purposes, the last thing they are going to want to deal with is a slow loading time because that will waste too much time during class and leave not much time for actual learning. Even if a school just uses your site on a computer in the library for students to do research with, it can be frustrating to the students because it causes them to loose much needed time for doing research because the site is taking too long to load.
Poor
The thing I liked the best: I liked all the different interactive aspects of your website.
The thing I liked the least: Please get rid of as much of the loading time as possible.
Overall Mark:
I can see the potential for educators/teachers being able to use a site like yours to help teach their students. I think there are a lot of students that would be able to benefit from it and help encourage them to learn more. I wish you and your site the best of luck in the future!
