What To Expect

The Class : Learn the basics of atmospheric and space sciences, space exploration, spacecraft design, rocketry, and orbits.

Hear about the current research in space through lectures from Lockheed Martin, Ball Aerospace, LASP, NOAA, NCAR, and CASA. The Class :

Launch a mini-satellite on a high altitude balloon that is designed and built by you and a team of students. The Class :

- Interactive - Interesting - Applicable - Fun

What to expect from this class : -If you are not here because you want to be here, then leave… -If you are here because you think this will be easier than GEEN 1400, then leave… -If you are here because you think this will be easier than Physics III, then leave… -If you are a slacker, then leave… -But if you want to work hard and achieve something great, then stay…

What to expect from this class : -Plan on being here for the full class (75 minutes) -Be ON-TIME -1 Minute Reports Each Class -Attendance -Homework (Only 6) -A lot of work -No cell phones or laptops

Survey Highlights

Class Survey : -Do you feel you learned anything in this class that will help you in future classes? -Definitely, teamwork and knowing how to meet deadlines -How to present -Typical design process -Everything from RFP to launch -Ability to problem solve

Class Survey : -Do you feel this class required too much work for the credit hours given? -51% - No, it’s worth the work -49% - Yes, there could have been one more credit hour attached to the class - Are you glad you took this class? -Definitely, it was by far my favorite course regardless of the high amount of work comparatively

Class Survey : -Would you recommend this class to a friend? -94% - Yes -4% - Already have -2%(1 person) - No -Did you like the team you were on? -92% - Yes -8% - No -Ultimate Goal: We worked well and were able to joke around and hang out outside of work. We even went to Dark Horse the other night in celebration.

Class Survey : -Did you enjoy the recovery trip? -I thought the trip was a blast. -Launch, yes. 8 hour recovery…no -Made for one heck of a story and memorable time.

Class Survey : -Other things you would like to say… -Way to keep us laughing even though we were the most stressed freshman on campus. -Most fun class this semester -I would take this class again if I could.
