This paper reports the establishment and practical results of the first trial of the spacecraft thermal design hands-on training program for the general public. This training is part of the two-week educational program that aims to find and grow up the potential people who are interested in commercial space utilization. The thermal design and its evaluation are some of the most difficult points for novices of the space industry. The program consists of the basic classroom lecture focusing on the differences from the thermal design of the normal commercial equipment and two kinds of hands-on training helping the students understanding. The hands-on training aims to evaluate thermal radiation properties. The training consists of the measurement with the standard instruments and thermal-vacuum test. The effectiveness of the whole training program is evaluated based on the questionnaire results from the students.
