Explorer 41 (also IMP-G ) was a satellite of the US space agency NASA as part of the Explorer program . It was part of the Interplanetary Monitor Platform (IMP) program, which was supposed to collect information about solar flares , among other things . In addition, studies of the terrestrial and galactic magnetic fields, the solar corpuscular radiation , the solar and the cosmic radiation should be carried out. In addition, the Apollo missions should be warned of solar flares. For this purpose, the satellite was placed in a strongly eccentric orbit that reached into the area between the earth and the moon (cislunar space). The satellite was spin stabilized. After an almost smooth mission with only a few interruptions in data transmission, it was decommissioned shortly after Apollo 17 landed on December 23, 1972.
