 Anders continued to take photographs while Lovell assumed control of the spacecraft so Borman could rest . Despite the difficulty resting in the cramped and noisy spacecraft , Borman was able to sleep for two orbits , awakening periodically to ask questions about their status . Borman awoke fully , however , when he started to hear his fellow crew members make mistakes . They were beginning to not understand questions and would have to ask for the answers to be repeated . Borman realized that everyone was extremely tired having not had a good night 's sleep in over three days . Taking command , he ordered Anders and Lovell to get some sleep and that the rest of the flight plan regarding observing the Moon be scrubbed . At first Anders protested saying that he was fine , but Borman would not be swayed . At last Anders agreed as long as Borman would set up the camera to continue to take automatic shots of the Moon . Borman also remembered that there was a second television broadcast planned , and with so many people expected to be watching he wanted the crew to be alert . For the next two orbits Anders and Lovell slept while Borman sat at the helm . On subsequent Apollo missions , crews would avoid this situation by sleeping on the same schedule .
