Spacecraft that will search for planetary systems around 40
million stars and observe the largest explosions in the universe have been chosen as the
next two missions in NASA's medium-class Explorer (MIDEX) program.
"In my 21 years at NASA, this is the most difficult selection
that I have had to make," said Dr. Edward Weiler, Associate Administrator for Space
Science, NASA Headquarters. "The number of first-class concepts being submitted to
NASA by the space science community for these smaller missions just keeps on
climbing."
The first mission, to be launched in 2003, is the Swift Gamma Ray
Burst Explorer, a three-telescope space observatory for studying gamma ray bursts.
Although gamma ray bursts are the largest known explosions in the universe, outshining the
rest of the universe when they explode unpredictably in distant galaxies, the underlying
cause of the explosion is a true mystery of astrophysics. Swift will have the unique
ability to rotate in orbit and point its gamma ray telescope, X-ray telescope, and
ultraviolet/optical telescope at gamma ray bursts within minutes of the burst's first
appearance. Since gamma ray bursts are believed to originate billions of light years away,
Swift will use these sources as beacons to probe distant regions of the universe.
During its three-year mission, Swift will also survey the sky for
new black holes and other sources of cosmic gamma rays. Swift will be led by Dr. Neil
Gehrels of NASA's Goddard Space Flight Center, Greenbelt, MD, at a total mission cost to
NASA of $163 million.
The second mission, to be launched in 2004, is the Full-sky
Astrometric Mapping Explorer (FAME), a space telescope designed to obtain highly precise
position and brightness measurements of 40 million stars. This rich database will allow
astronomers to accurately determine the distance to all of the stars on this side of the
Milky Way galaxy, detect large planets and planetary systems around stars within 1,000
light years of the Sun, and measure the amount of dark matter in the galaxy from its
influence on stellar motions.
This 30-fold improvement in accuracy over previous position-
measuring spacecraft will establish a new standard for measuring distances in astronomy
and help resolve questions about the size and age of the universe. FAME's five-year
mission will be led by Dr. Kenneth J. Johnston of the U.S. Naval Observatory, Washington,
DC, at a total mission cost to NASA of $162 million.
"MIDEX missions not only return first-class science results,
they continue NASA's trend toward greatly lowered mission costs via innovative mission
planning and operations," Weiler added. "For example, FAME utilizes a solar sail
instead of thrusters to provide the propulsive force needed to re-orient itself to scan
the entire sky, and Swift uses its own on-board artificial intelligence software to point
itself at new targets faster than human controllers ever could."
The selection of these missions is the second step of a two- step
process. In the first step, NASA selected five proposals in January 1999 for detailed
four-month feasibility studies. Funded by NASA at $350,000 each, these studies focused on
cost, management, and technical plans, including small business involvement and
educational outreach.
The first two MIDEX missions, selected in 1996, are the Imager for
Magnetopause-to-Aurora Global Exploration (IMAGE) and the Microwave Anisotropy Probe
(MAP). IMAGE will be launched in the winter of 2000 to study the global response of the
Earth's magnetosphere to changes in the solar wind. MAP will be launched in November 2000
to probe conditions in the early universe by measuring the properties of the cosmic
microwave background radiation over the full sky.
The selected proposals were among 31 full proposals originally
submitted to NASA in August 1998 in response to an Explorer Program Announcement of
Opportunity issued in March 1998. The Explorer Program is designed to provide frequent,
low-cost access to space for physics and astronomy missions with small to mid-sized
spacecraft. The Explorer Program is managed by NASA's Goddard Space Flight Center,
Greenbelt, MD, for the Office of Space Science, Washington, DC.

The MPA is the major
German institution dedicated to theoretical research in astrophysics. It is situated a few
kilometers north of the center of Munich on a campus shared with the MPI fuer
Extraterrestriche Physik, the Technical University of Munich, and several other research
institutes. The MPA has about a dozen permanent staff members who work with a somewhat
larger number of postdoctoral researches and of graduate students; it also runs a vigorous
visitor programme. The institute is housed in an attractive specially designed building
which contains excellent library and computer facilities. It also has a privileged access
to supercomputer facilities at the neighbouring MPP Computer Center. Current areas of
interest include stellar atmospheres, the structure and evolution of single and multiple
stars, accretion theory, supernovae, star formation, high energy astrophysics,
computational fluid dynamics, the structure and evolution of galaxies, the physics of
active galactic nuclei, gravitational lensing, galaxy formation and galaxy clustering,
microwave background studies, physical cosmology, and particle astrophysics. Further
information may be found on our Web page - http://www.mpa-garching.mpg.de
. The MPA is currently seeking to fill a number of postdoctoral position intended for
promising young scientists who completed their PhD within the last five years. They are
awarded initially for two years which can be renewed for up to another three. Annual
salary is in the range 65000-80000 DM before tax, depending on age and family status.
Interested scientists are invited to apply to:
The Appointments Committee
Max-Planck-Institut fuer Astrophysik
Karl-Schwarzschild-Str. 1
85740 Garching bei Muenchen.
Candidates should send a full curriculum vitae, a publication list and a summary of
current research interests to this address by 15 December 1999. They should also arrange
for three reference letters to arrive by the same date. Later applications will also be
considered until all posts are filled.
The MPA is an equal opportunity employer and particularly welcomes applications from women
and from minorities.
