After traveling more than 4,500 miles in 30 days, the Roadtrippers book a last-minute interview with Randii Wessen, an engineer at the Jet Propulsion Laboratory in Los Angeles. Randii shares his story of constant determination-wisdom that resonates with Nekeed. The last interview ends with Laura Danly, curator at the Griffith Observatory. Laura shares her story of arduous schooling to land a job as a NASA astronomer-only to realize she's happiest when she shares her astronomical knowledge with others. Ending their journey with a better sense of themselves and their futures, the team shares their final reflections and says their goodbyes.
