NASA collage of WMAP related imagery spacecraft, CMB spectrum and background imageThe Wilkinson Microwave Anisotropy Probe WMAP, originally known as the Microwave Anisotropy Probe MAP, was a spacecraft operating from 2. CMB  the radiant heat remaining from the Big Bang. Headed by Professor Charles L. Bennett of Johns Hopkins University, the mission was developed in a joint partnership between the NASA Goddard Space Flight Center and Princeton University. The WMAP spacecraft was launched on June 3. Florida. The WMAP mission succeeded the COBE space mission and was the second medium class MIDEX spacecraft in the NASA Explorers program. In 2. 00. 3, MAP was renamed WMAP in honor of cosmologist David Todd Wilkinson 1. After 9 years of operations, WMAP was switched off in 2. Planck spacecraft by ESA in 2. WMAPs measurements played a key role in establishing the current Standard Model of Cosmology the Lambda CDM model. The WMAP data are very well fit by a universe that is dominated by dark energy in the form of a cosmological constant. Other cosmological data are also consistent, and together tightly constrain the Model. In the Lambda CDM model of the universe, the age of the universe is 7. The WMAP missions determination of the age of the universe is to better than 1 precision. The current expansion rate of the universe is see Hubble constant 7. Mpc1. The content of the universe currently consists of 6. CDM that neither emits nor absorbs light and 6. Less than 1 of the current content of the universe is in neutrinos, but WMAPs measurements have found, for the first time in 2. The contents point to a Euclidean flat geometry, with curvature kdisplaystyle Omega k of 3. The WMAP measurements also support the cosmic inflation paradigm in several ways, including the flatness measurement. The mission has won various awards according to Science magazine, the WMAP was the Breakthrough of the Year for 2. This missions results papers were first and second in the Super Hot Papers in Science Since 2. Of the all time most referenced papers in physics and astronomy in the INSPIRE HEP database, only three have been published since 2. WMAP publications. Bennett, Lyman A. Sigma As 227 Program Directv' title='Sigma As 227 Program Directv' />Page, Jr., and David N. Spergel, the latter both of Princeton University, shared the 2. Shaw Prize in astronomy for their work on WMAP. Bennett and the WMAP science team were awarded the 2. Gruber Prize in cosmology. As of October 2. 01. WMAP spacecraft is derelict in a heliocentricgraveyard orbit after 9 years of operations. All WMAP data are released to the public and have been subject to careful scrutiny. The final official data release was the nine year release in 2. Some aspects of the data are statistically unusual for the Standard Model of Cosmology. For example, the largest angular scale measurement, the quadrupole moment, is somewhat smaller than the Model would predict, but this discrepancy is not highly significant. A large cold spot and other features of the data are more statistically significant, and research continues into these. Objectivesedit. The universes timeline, from inflation to the WMAP. The WMAP objective was to measure the temperature differences in the Cosmic Microwave Background CMB radiation. The anisotropies then were used to measure the universes geometry, content, and evolution and to test the Big Bang model, and the cosmic inflation theory. For that, the mission created a full sky map of the CMB, with a 1. The map required the fewest systematic errors, no correlated pixel noise, and accurate calibration, to ensure angular scale accuracy greater than its resolution. The map contains 3,1. HEALPix scheme to pixelize the sphere. The telescope also measured the CMBs E mode polarization,1. Its service life was 2. L2 position, 2 years of observation.

The WMAP was preceded by two missions to observe the CMB i the Soviet RELIKT 1 that reported the upper limit measurements of CMB anisotropies, and ii the U. S. COBE satellite that first reported large scale CMB fluctuations. The WMAP was 4. 5 times more sensitive, with 3. COBE satellite predecessor. The successor European Planck mission operational 2. WMAP and observed in 9 frequency bands rather than WMAPs 5, allowing improved astrophysical foreground models. SpacecrafteditThe telescopes primary reflecting mirrors are a pair of Gregorian 1. They are shaped for optimal performance a carbon fibre shell upon a Korex core, thinly coated with aluminium and silicon oxide. The secondary reflectors transmit the signals to the corrugated feedhorns that sit on a focal plane array box beneath the primary reflectors. Illustration of WMAPs receivers. The receivers are polarization sensitive differential radiometers measuring the difference between two telescope beams. The signal is amplified with HEMTlow noise amplifiers, built by the National Radio Astronomy Observatory. There are 2. 0 feeds, 1. The directional separation azimuth is 1. To avoid collecting Milky Way galaxy foreground signals, the WMAP uses five discrete radio frequency bands, from 2. GHz to 9. 4 GHz. 1. The WMAPs base is a 5. CMB observations, by keeping the craft constantly angled at 2. Sun. Upon the array sit a bottom deck supporting the warm components and a top deck. The telescopes cold components the focal plane array and the mirrors, are separated from the warm components with a cylindrical, 3. Passive thermal radiators cool the WMAP to ca. K they are connected to the low noise amplifiers. The telescope consumes 4. W of power. The available telescope heaters are emergency survival heaters, and there is a transmitter heater, used to warm them when off. The WMAP spacecrafts temperature is monitored with platinum resistance thermometers. The WMAPs calibration is effected with the CMB dipole and measurements of Jupiter the beam patterns are measured against Jupiter. The telescopes data are relayed daily via a 2 GHz transponder providing a 6. Deep Space Network telescope. The spacecraft has two transponders, one a redundant back up they are minimally active ca. The telescopes position is maintained, in its three axes, with three reaction wheels, gyroscopes, two star trackers and sun sensors, and is steered with eight hydrazine thrusters.
