Discuss how much margin there is before the vehicle becomes too heavy to launch with the identified propulsion system. Are you holding any mass in reserve (i.e., are you planning for any mass growth as the design matures)? If so, how much?

| − | The presentation of the PDR shall be well prepared with a professional overall appearance. This includes, but is not limited to, the following: easy-to-see slides; appropriate placement of pictures, graphs, and videos; professional appearance of the presenters; speaking clearly and loudly; referring to the slides, not reading them; and communicating to the panel in an appropriate and professional manner.
| |
| − |
| |
| − | This review should be viewed as the opportunity to convince the review panel that the preliminary design will meet all requirements, has a high probability of meeting the mission objectives, and can be safely constructed, tested, launched, and recovered. Upon successful completion of the PDR, the team is given the authority to proceed into the final design phase of the life cycle that will culminate in the Critical Design Review.

Upon successful completion of the CDR, the team is given the authority to proceed into the construction and verification phase of the life cycle which will culminate in a Flight Readiness Review.
