TL;DR: The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sky continuously since 12 August 2009 as discussed by the authors.

TL;DR: The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009 as mentioned in this paper, and it will continue to gather scientific data until the end of its cryogenic lifetime.

TL;DR: The ESA's Planck satellite was launched 14 May 2009 and has been scanning the microwave and sub-millimetre sky continuously since 12 August 2009 as discussed by the authors, where it has measured gravitational lensing of CMB anisotropies at greater than 25 sigma.

TL;DR: The design, error budget, and preliminary test results of a 50-56-GHz synthetic aperture radiometer demonstration system are presented and one result suggests a hybrid image synthesis algorithm in which long baselines are processed by a fast Fourier transform and the short baselines have their processing handled by a more precise algorithm which can handle small anomalies among antenna and receiver responses.
