NASA engineer Daniel Cohen, who works in the field of navigation, guidance, and control (GN&C) at the Johnson Space Center, has become a mentor to several agency interns despite his heavy workload. One of his mentees, Rice University student Malvika Bhardwaj, recounted how she once asked Cohen if he would have time to continue mentoring interns given his busy schedule. He replied: "You decide what matters." This response became an example for Bhardwaj of Cohen's mentoring approach—prioritization and genuine interest in the development of young professionals. The story is published in honor of National Mentorship Day, observed on October 27, which aims to highlight the importance of mentorship in professional development. Mentorship plays a crucial role in preparing the next generation of specialists for the space industry. Experienced NASA engineers like Cohen pass on to interns not only technical knowledge in the field of spacecraft navigation and control, but also decision-making skills, time management, and professional ethics. Such programs help students like Bhardwaj gain practical experience working on real agency projects and prepare for future careers in the aerospace industry. The story illustrates how the personal commitment of experienced NASA employees to educating young people contributes to building the agency's talent pipeline and maintains the continuity of knowledge in complex technical fields such as spacecraft navigation and control systems.
