ESLAB 2013 - The Universe as seen by Planck: An international conference dedicated to an in-depth look at the initial scientific results from the Planck mission. ESA/ESTEC, Noordwijk, The Netherlands, 2-5 April 2013. The ESLAB presentations are available online here.
End of Planck operations: The final command to the Planck satellite was sent on 23 October 2013, marking the end of operations of an extraordinary cosmology mission. ESA’s Planck space telescope has been turned off after nearly 4.5 years soaking up the relic radiation from the Big Bang and studying the evolution of stars and galaxies throughout the Universe’s history. The high-quality data the mission has produced will continue to be scientifically explored in the years to come. Click to know more.
Celebrating the legacy of ESA’s Planck mission: From the tiniest fraction of a second after the Big Bang to the evolution of stars and galaxies over 13.8 billion years, ESA’s Planck space telescope has provided new insight into the history of our Universe. Although science observations are now complete, the legacy of the Planck mission lives on. Click to know more.
End of routine operations: Planck's decommissioning activities started on October 4, 2013. The routine operations of Planck have ended after executing its last observation of the Crab Nebula. On October 19, the sorption cooler and the two instruments (LFI & HFI) were switched-off.
Planck was selected as the third Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific Programme, and is today part of its Cosmic Vision Programme. It is designed to image the anisotropies of the Cosmic Background Radiation Field over the whole sky, with unprecedented sensitivity and angular resolution. Planck will provide a major source of information relevant to several cosmological and astrophysical issues, such as testing theories of the early universe and the origin of cosmic structure. The scientific development of the mission is directed by the Planck Science Team.
Planck was formerly called COBRAS/SAMBA. After the mission was selected and approved (in late 1996), it was renamed in honor of the German scientist Max Planck (1858-1947), Nobel Prize for Physics in 1918.
Planck was launched in 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 surveying the sky for a large part of 2013, providing even more data to improve the Planck final results. Read full story. 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.
