| Planck first light yields promising results |
| Preliminary results from the Planck First Light Survey, performed to demonstrate the stability of the instruments and the ability to calibrate them over long periods, indicate that the data quality is excellent. This bodes well for the full sky survey that has just begun. |

| Planck instruments reach their coldest temperature |
| The extremely low operational temperature of just a tenth of a degree above absolute zero (0.1 K) has been reached on the detectors of Planck's High Frequency Instrument (HFI). This makes the HFI detectors the coldest known objects in outer space. The achievement, seven weeks after launch, marks a key milestone for the Planck mission. The spacecraft's active cooling system has now reached its final operational conditions and the two instruments onboard Planck (HFI and the Low Frequency Instrument, LFI) are now both at their cryogenic operational temperatures. |

| Successful Launch Readiness Review ahead of the launch of Herschel and Planck |
| The launcher for Herschel and Planck has been declared ready for launch following the successful conclusion of the Launch Readiness Review, RAL (Revue d'Aptitude au Lancement), held on 9 May and the close-out review held on 12 May. The launch from the European Spaceport at Kourou, French Guiana, is scheduled for 14 May 2009. |

| Planck Telescope Qualification Model Test |
| The structure of the Planck telescope has to remain dimensionally stable, maintaining the mirror positions with an accuracy better than 30 µm, over a wide temperature range. The qualification model of the telescope has recently been tested to correlate the thermoelastic model used in its design with actual performance. |
