The last time the Philae probe contacted the Earth on July 9, the scientists had 12 minutes to “communicate”. The location of the probe on the surface of the comet Churyumov-Gerasimenko is still unknown. Scientists cannot contact the device using Rosetta.

Probe Philae descended to the surface of the comet Churyumov-Gerasimenko on November 12, 2014, made several “jumps” and stopped in the shadow of a “cliff”. Energy reserves were depleted on November 15, and the machine the size of a washing machine went into hibernation mode. Seven months later, on June 13, 2015, Philae “woke up” and began to transmit information about his condition.
The Philae probe contacted Earth only eight times . Two weeks passed between the seventh and eighth communication sessions. This time, scientists have not "talked" with the device for twelve days.
Scientists noted that the eighth session, despite its short duration, was distinguished by high quality communications. The probe transmitted the comet nucleus data obtained by the CONSERT instrument (COmet Nucleus Sounding Experiment by Radiowave Transmission).
The Philae probe uses the Rosetta spacecraft to communicate with Earth. The orbit of this device does not allow for regular communication sessions: perhaps experts will change it. Philae Tools (Clickable) ESA
