NO plagiarism! ZERO tolerance! The instructor (Prof. Ryu) WILL read and evaluate your report.

All homework assignments and one-minute papers must be submitted in printed form during class. Email submissions will not be accepted.

7. One minute paper
At end of class, the instructor will request students to fill one Minute Paper to establish their degree of understanding and address to questions or issues still unanswered. Please download the template.

8. No Plagiarism Policy
Plagiarism consists of passing off as one's own ideas, words, writings, etc., which belong to another. Plagiarism is one of the worst academic sins, for the plagiarist destroys the trust among colleagues without which knowledge and learning cannot be safely communicated.

9. Lecture material and topics

• Week 1

Introduction: Space, Moon, Engineering, and Science

• Week 2

1) March 14, 2024: Starship's Third Flight Test
The third flight test of Starship is targeted to launch Thursday, March 14. The 110-minute test window opens at 7:00 a.m. CT.
You can watch the live launch webcast at https://www.spacex.com/launches starting approximately 30 minutes ahead of liftoff.
The third flight test aims to build on what we’ve learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship’s payload door, a propellant transfer demonstration during the upper stage’s coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship. It will also fly a new trajectory, with Starship targeted to splashdown in the Indian Ocean. This new flight path enables us to attempt new techniques like in-space engine burns while maximizing public safety.
This rapid iterative development approach has been the basis for all of SpaceX’s major innovative advancements, including Falcon, Dragon, and Starlink. Recursive improvement is essential as we work to build a fully reusable transportation system capable of carrying both crew and cargo to Earth orbit, help humanity return to the Moon, and ultimately travel to Mars and beyond.
