The commander David Scott and the lunar module pilot James Irwin stayed on the surface of the moon for three days, and the total time outside the lunar module was 18 and a half hours. Two astronaut The first lunar rover in the history of driving made their crossing distance on the moon much farther than the previous missions. They collected about 77 kilograms of lunar rock specimens. At the same time, Alfred Worden, the pilot of the command module, stayed in the command module and circled the moon. He used panoramic cameras, gamma ray spectrometers, mapping cameras, laser altitudes, mass spectra, sub satellites launched after the mission and other equipment in the Scientific Instrument Module (SIM) to conduct a detailed study of the lunar surface environment.
After this very successful mission, the exposure of the agreement between the three astronauts and businessman H. Walter Eiermann was somewhat detrimental to their reputation. Scott carried 398 unauthorized first day covers in his spacesuit. Elman promised to give each astronaut a current deposit of 7000 dollars to exchange for 100 first day covers. He also told the astronauts that he would not sell the first day cover before the end of the Apollo program.
Scott sent a hundred first day covers to Elman in Stuttgart, Germany, after the mission ended. Elman also gave the first day cover to Herman E. Sieger, a stamp dealer in Lorch, Germany, who first came up with the business. Serge publicly sold these first day covers in Germany at an average price of 1500 US dollars. After learning the news, Scott informed Elman to stop selling. The three astronauts also decided not to accept any money from Elman. NASA confiscated the remaining 298 first day covers.
The three astronauts were formally warned, and their official military service assessment report also included this event to reflect on their "lack of judgment".
