Darwin (Space IR Interferometry Mission)

Darwin is a proposal for a European infrared interferometer in space. Its first aim is to detect Earth-like planets around nearby stars, and then to search for a signature of life, ozone in an atmosphere. It could also be used as a general-purpose infrared observatory.
Darwin was proposed to the European Space Agency (ESA) for a Cornerstone Mission in its Horizon 2000 Plus plan. In October 1995, ESA decided to study such an infrared interferometer as an option for its Interferometer Cornerstone. The Darwin and Edison teams have combined to promote the selection by ESA of this option. The Darwin advocacy team members are also members of the International Working Group on Space Interferometry , a pressure group for this type of mission. Final selection on cost, science and technology grounds will be made around 2000, for a launch in the period 2009 - 2017.

Gravity Probe B Relativity Mission (Stanford)

Gravity Probe B is the relativity gyroscope experiment being developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity. The experiment will check, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth satellite orbiting at 400-mile altitude directly over the poles. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are warped by the presence of the Earth, and, more profoundly, how the Earth's rotation drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe.

Magellan Mission to Venus

NASA's Magellan spacecraft made a dramatic conclusion to its highly successful mission at Venus when it is commanded to plunge into the planet's dense atmosphere Tuesday, October 11, 1994. During its four years in orbit around Earth's sister planet, the spacecraft has radar-mapped 98 percent of the surface and collected high-resolution gravity data of Venus. The purpose of the crash landing is to gain data on the planet's atmosphere and on the performance of the spacecraft as it descends. Up-to-date status reports will be available from this WWW page, which also offers Venus images and other highlights from the mission.

McDonnell Center for the Space Sciences

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.

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.

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.
See the MSX Celestial Backgrounds Team Home Page for additional details.

Project Galileo: Bringing Jupiter to Earth

Launched in 1989, the Galileo spacecraft arrived at Jupiter on December 7, 1995, when it fired its main engine for a successful orbit capture around Jupiter. On that day, Galileo's atmospheric probe plunged into Jupiter's atmosphere and relayed information on the structure and composition of the solar system's largest planet. The spacecraft's orbiter will spend the next two years orbiting the giant planet, studying Jupiter and its moons (encountering one moon during each orbit), and returning a steady stream of images and scientific data. The first two encounters were successfully performed with Jupiter's largest moon, Ganymede, on June 27, 1996 and September 6, 1996.

The purpose of these Summer Schools, held every second summer onboard a river cruise ship on the Volga and organised jointly by the Radiophysical Research Institute (NIRFI), Nizhniy Novgorod, Russia and the Uppsala Division of the Swedish Institute of Space Physics (IRFU), Uppsala, Sweden, is to give an introduction to modern space plasma physics by bringing together experienced researchers, young scientists and scholars in astrophysics, space physics and plasma physics for a fruitful exchange of ideas across areas of interest, language, culture and age barriers.
The topics covered include linear and non-linear plasma physics, waves and radiation phenomena in plasma, waves in random media and turbulence, planetary, solar and stellar coronal plasma, plasma under extreme conditions in space, space plasma radio emission, radio methods for investigating space plasma environments, and the use of the Earth's ionosphere and magnetosphere as a space plasma laboratory for model experiments simulating phenomena in other plasma environments.

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.
