Komarov was selected to command the Soyuz 1, in 1967, with Yuri Gagarin as his backup cosmonaut. The cosmonauts knew that the spacecraft had major safety problems, but Komarov stated that if he were to refuse to fly, Gagarin would be forced to go instead. Komarov chose to fly to protect Gagarin, and insisted before the flight that his funeral be open-casket so that the Soviet leadership could see what they had done. During the preparations for the spaceflight, both cosmonauts were working twelve- to fourteen-hour days. On orbital insertion, the solar panels of the Soyuz module failed to fully deploy thereby preventing the craft from being fully powered and obscuring some of the navigation equipment. Komarov reported: "Conditions are poor. The cabin parameters are normal, but the left solar panel didn't deploy. The electrical bus is at only 13 to 14 amperes. The HF (high frequency) communications are not working. I cannot orient the spacecraft to the sun. I tried orienting the spacecraft manually using the DO-1 orientation engines, but the pressure remaining on the DO-1 has gone down to 180." Komarov tried unsuccessfully to orient the Soyuz module for five hours. The craft was transmitting unreliable status information, and lost communications on orbits 13 through 15 due to the failure of the high frequency transmitter that should have maintained radio contact while the craft was out of range of the ultra high frequency (UHF) ground receivers.
