PLANCK R3 frequency HFI map 353 GHz survey collection

Planck was launched on 14 May 2009, and the minimum requirement for success was for the spacecraft to complete two whole surveys of the sky. In the end, Planck worked perfectly for 30 months, about twice the span originally required, and completed five full-sky surveys with both instruments.

Able to work at slightly higher temperatures than HFI, the Low Frequency Instrument (LFI) continued to survey the sky for a large part of 2013, providing even more data to improve the Planck final results. Planck was turned off on 23 October 2013. The high-quality data the mission has produced will continue to be scientifically explored in the years to come.Original acknowledgement for data: ESA and the Planck Collaboration
