INACTIVE LINK ? - 256 --- McDonnell Center for the Space Sciences (MCSS)
The McDonnell Center for the Space Sciences exists to encourage scientists to work together on research problems that span or transcend traditional departmental lines. This is done through formal programs such as regular colloquia, and informally through the common bond of fellowship in the Center. Space science, broadly defined as the study of the universe and our relationship to it, is simply too vast an area to be the province of a single discipline. Understanding the formation of the solar system is equally the task of the chemist who measures isotope effects in meteorites, the astronomer who observes planetary atmospheres or interstellar dust, and the theoretical physicist who studies gravitational collapse. Faculty and students of the Center thus belong to one of the basic, traditional science departments, yet overlap strongly in their research work. - Categories: dept space

INACTIVE LINK ? - 81 --- Microlensing Planet Finder Project (MPF, ex-GEST)
The Microlensing Planet Finder Project (MPF) is by far the most powerful proposed observatory for finding large numbers of planetary systems. It answers the following questions: How many planets are there? How are they distributed in mass and distance from their parent stars, and in distance from the Galactic Center? How many have large moons? How many have been expelled from their systems? None of these questions are fully addressed by other techniques particularly if the abundance is low. MPF will do this by observing microlensing signals from 100 million stars in the Galactic bulge for 4 observing seasons, and it will have sensitivity to planets with masses as low as 0.1 M\oplus at separations > 0.7 AU. MPF will be sensitive to analogs of all the planets in the solar system except for Mercury and Pluto and will complement the Kepler mission. - Categories: telescope optical planetary space

Microvariability and Oscillations of STars (MOST)
MOST is Canada's first space science microsatellite and its first optical space telescope project, aiming for launch in late 2001. MOST is designed to measure (as its acronym implies) Microvariability & Oscillations of STars in broadband light with a precision of a few micromagnitudes over timescales from minutes to days. The resulting eigenfrequency data will be used primarily for stellar seismology, to probe the structure and ages of Sun-like stars, magnetic stars, Wolf-Rayet stars and halo subdwarfs. The subdwarfs are expected to yield age estimates which would place a meaningful lower limit on the age of the Universe. MOST should also be capable of confirming the presence of giant extrasolar planets identified in Doppler surveys. - Categories: telescope optical space

Midcourse Space Experiment (MSX)
The MSX observatory is a Ballistic Missile Defense Organization project which offers major benefits for both the defense and civilian sectors. It was launched on a Delta II vehicle on April 24, 1996, into a 900 km, polar, near-Sun synchronous orbit. The spacecraft featured an advanced multispectral image capability to gather data on test targets and space background phenomena.
The infrared sensors operated at 11 to 12 degrees Kelvin by employing a solid hydrogen cryostat. The IR instruments span the range 4.2 - 26 microns. The focal plane array consists of five bands and the radiometer beam-size is more than 25 times smaller than IRAS. As a result, much greater spatial resolution than anything currently available has been obtained. The cryogen phase of the mission ended on 26 February 1997. During the ten month cryogen phase of the mission over 200 Giga Bytes of data on Celestial Backgrounds were obtained.

WAVES : The Radio and Plasma Wave Investigation on the WIND Spacecraft (waves)
WAVES radio astronomy instrument on the ISTP-Wind spacecraft. - Categories: telescope physics radio space

WIND spacecraft
WIND was launched on November 1, 1994 and is the first of two NASA spacecraft in the Global Geospace Science (GGS) initiative (the second spacecraft being POLAR). WIND is also part of the International Solar Terrestrial Physics Project (ISTP), it was specially designed to make coordinated observations with the other ISTP spacecraft (Geotail, Interball, Equator-S, Cluster,...). WIND's full capacity duration was of three years, but it has been extended: WIND orbits until 2006.
The science objectives of the WIND mission are: provide complete plasma, energetic particle, and magnetic field input for magnetospheric and ionospheric studies; determine the magnetospheric output to interplanetary space in the up-stream region; investigate basic plasma processes occurring in the near-Earth solar wind; provide baseline ecliptic plane observations to be used in heliospheric latitudes from ULYSSES. - Categories: telescope particles radio space

Wide Field Infrared Explorer (WIRE)
This is the website for NASA's Wide Field Infrared Explorer (WIRE). The primary purpose of WIRE was a four month infrared survey of the universe, focusing specifically on starburst galaxies and luminous protogalaxies.

Wilkinson Microwave Anisotropy Probe (WMAP)
The WMAP mission is designed to determine the geometry, content, and evolution of the universe via a 13 arcminute FWHM resolution full sky map of the temperature anisotropy of the cosmic microwave background radiation. The choice of orbit, sky-scanning strategy and instrument/spacecraft design were driven by the goals of uncorrelated pixel noise, minimal systematic errors, multifrequency observations, and accurate calibration. The skymap data products derived from the WMAP observations have 45 times the sensitivity and 33 time the angular resolution of the COBE DMR mission. - Categories: telescope radio space

Wilkinson Microwave Anisotropy Probe (WMAP)
NASA has selected WMAP as one of the next MIDEX missions. It will map the microwave background fluctuations over the whole sky and provide insights into the formation of galaxies and the basic parameters of cosmology. - Categories: telescope education radio space

Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE)
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was a pioneering effort to explore polarization and photometry in the ultraviolet (UV) spectrum. It was the first and most comprehensive effort to exploit the unique powers of polarimetry at wavelengths not visible on Earth. The instrument was designed and built at the University of Wisconsin Space Astronomy Laboratory in the 1980's. WUPPE flew on two NASA Space Shuttle missions: ASTRO-1 and ASTRO-2. - Categories: telescope space ultraviolet
