Planck was a space observatory operated by the European Space Agency ESA from 2. CMB at microwave and infra red frequencies, with high sensitivity and small angular resolution. The mission substantially improved upon observations made by the NASAWilkinson Microwave Anisotropy Probe WMAP. Planck provided 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 as of 2. Universe. The project was started around 1. COBRASSAMBA the Cosmic Background Radiation Anisotropy SatelliteSatellite for Measurement of Background Anisotropies. It was later renamed in honour of the German physicist Max Planck 1. Built at the Cannes Mandelieu Space Center by Thales Alenia Space, and created as a medium sized mission for ESAs Horizon 2. Planck was launched in May 2. EarthSun L2 point by July, and by February 2. On 2. 1 March 2. 01. February 2. 01. 5. At the end of its mission Planck was put into a heliocentric orbit and passivated to prevent it from endangering any future missions. The final deactivation command was sent to Planck in October 2. ObjectiveseditThe mission had a wide variety of scientific aims, including 3high resolution detections of both the total intensity and polarization of primordial CMB anisotropies,creation of a catalogue of galaxy clusters through the SunyaevZeldovich effect,observations of the gravitational lensing of the CMB, as well as the integrated SachsWolfe effect,observations of bright extragalactic radio active galactic nuclei and infrared dusty galaxy sources,observations of the Milky Way, including the interstellar medium, distributed synchrotron emission and measurements of the Galactic magnetic field, andstudies of the Solar System, including planets, asteroids, comets and the zodiacal light. Planck had a higher resolution and sensitivity than WMAP, allowing it to probe the power spectrum of the CMB to much smaller scales 3. It also observed in nine frequency bands rather than WMAPs five, with the goal of improving the astrophysical foreground models. It is expected that most Planck measurements will be limited by how well foregrounds can be subtracted, rather than by the detector performance or length of the mission, a particularly important factor for the polarization measurements. The dominant foreground radiation depends on frequency, but could include synchrotron radiation from the Milky Way at low frequencies, and dust at high frequencies. Instrumentsedit.

The spacecraft carries two instruments the Low Frequency Instrument LFI and the High Frequency Instrument HFI. Both instruments can detect both the total intensity and polarization of photons, and together cover a frequency range of nearly 8. GHz from 3. 0 to 8. GHz. The cosmic microwave background spectrum peaks at a frequency of 1. GHz. Plancks passive and active cooling systems allow its instruments to maintain a temperature of 2. C 4. 59. 4. 9 F, or 0. C above absolute zero. From August 2. 00. Planck was the coldest known object in space, until its active coolant supply was exhausted in January 2. NASA played a role in the development of this mission and contributes to the analysis of scientific data. Its Jet Propulsion Laboratory built components of the science instruments, including bolometers for the high frequency instrument, a 2.

NAThe HFI was sensitive between 1. GHz, using 4. 8 bolometric detectors, manufactured by JPLCaltech,6 optically coupled to the telescope through cold optics, manufactured by Cardiff Universitys School of Physics and Astronomy,7 consisting of a triple horn configuration and optical filters, a similar concept to that used in the Archeops balloon borne experiment. These detection assemblies are divided into 6 frequency bands centred at 1. GHz, each with a bandwidth of 3. Of these six bands, only the lower four have the capability to measure the polarisation of incoming radiation the two higher bands do not. On 1. January 2. 01. Plancksdilution refrigerator had been exhausted, and that the HFI would become unusable within a few days. By this date, Planck had completed five full scans of the CMB, exceeding its target of two. The LFI cooled by helium 4 was expected to remain operational for another six to nine months. Service Moduleedit.

Taken during presentations of the first results for the missions, Cannes, October 2. A common service module SVM was designed and built by Thales Alenia Space in its Turin plant, for both the Herschel Space Observatory and Planck missions, combined into one single program. The overall cost is estimated to be 7. Planck9 and 1,1. Herschel mission. Both figures include their missions spacecraft and payload, shared launch and mission expenses, and science operations. Structurally, the Herschel and Planck SVMs are very similar. Both SVMs are octagonal in shape and each panel is dedicated to accommodate a designated set of warm units, while taking into account the dissipation requirements of the different warm units, of the instruments, as well as the spacecraft. On both spacecraft, a common design was used for the avionics, attitude control and measurement ACMS, command and data management CDMS, power, and tracking, telemetry and command TT C subsystems. All units on the SVM are redundant. Strength of materials by s k mondal pdf by S. Dharmaraj. Strength of materials by s k mondal pdf Published on Jan 1.
