The
Daily Martian Weather Report is produced by the Mars Global Surveyor Radio
Science Team (MGS RST). When the MGS mapping sequence begins, the page will
contain a daily weather report for the planet Mars based on radio occultation
measurements of the temperature and pressure profiles of the Martian atmosphere.
Currently, the site contains information about the MGS mission and the Radio
Science Team, the radio occultation technique for study of planetary atmospheres,
profiles of the atmosphere of Venus acquired during occultations of the Magellan
spacecraft, and information for K-12 educators interested in e-mail
communications between their classes and members of the MGS RST.

Dartmouth
College Physics and Astronomy
In
space physics, active areas of research include theoretical studies of space
plasmas, computer simulations of plasmas, studies of auroral particle
acceleration and heating, investigations of the ionosphere and magnetosphere,
and studies of geomagnetic storms. The observational space physics program at
Dartmouth uses ground-based, rocket-launched, and satellite instrumentation to
study the ionosphere and magnetosphere. Observational work in astronomy is
carried out not only at the MDM Observatory, but at national and international
facilities including the Hubble Space Telescope. Ongoing research includes
optical, UV and X-ray studies of supernovae and supernova remnants,
investigations of the interstellar medium, shock waves, and Wolf-Rayet stars,
optical studies of X-ray binaries and cataclysmic variable stars. Additional
work focuses on cosmology, the large-scale structure of the universe, and the
end states of stellar evolution. The theoretical particle physics and cosmology
group at Dartmouth conducts research into general relativity, field theory,
particle physics and phase transitions in the early universe, and baryogenesis,
as well as investigations of star formation and the origins of large scale
structure in the universe.
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.
Data
Reduction Expert Assistant
( DRACO )
The
use of large format detectors, increased access to very large astronomical
databases, and other developments in observational astronomy have led to the
situation where many astronomers are overwhelmed by the reduction and analysis
process. Draco is a novel approach to data reduction and analysis which works in
conjunction with existing analysis systems such as STSDAS/IRAF, IDL, etc. Draco
takes on much of the mechanics of the process, allowing the astronomer to spend
more time understanding the physical nature of the data.

Deep
Near Infrared Survey of the Southern Sky
( DENIS )
DENIS
is a deep complete survey of the astronomical sources of the Southern Sky in 2
near-infrared bands (J at 1.25 micron & K at 2.16 micron) and one optical
band (I at 0.8 micron) simultaneously, using a one meter ground-based telescope
at La Silla (Chile), with limiting magnitudes 18.5, 16.5 and 14.0, respectively.

will be a complete deep near infrared survey of the southern sky, with the
objective to provide full coverage in 2 near infrared bands (J at 1.25 micron
and K at 2.2 micron) and one optical band (I at 0.8 micron), using a
ground-based telescope and digital array detectors. The products of this survey
will be databases of calibrated images, extended sources, and small objects. In
addition catalogs of small and extended sources will be produced. We expect the
survey to be completed within five years; restricted access to the databases is
possible during the second half of the survey. The production of catalogs (to be
distributed) will take a few additional years.

Conference
on Disks, Planetesimals and Planets, Puerto de la Cruz, Tenerife, SPAIN, 24-28
January 2000.
The recent discoveries of extrasolar planets and the progress in studies of
disks around pre-main sequence and main sequence stars highlight the need of
better understanding the formation and evolution of planetary systems. Many
groups and observatories are dedicating important efforts towards these goals.
The 1998 international time of the Canary Islands Observatories is fully devoted
to studies related to these topics, making use of spectroscopic, polarimetric
and photometric techniques in the optical, as well as near-IR photometry. The
conference is the frame where the large amount of data collected with the
facilities in the Canary Islands will be presented. In addition, contributions
from participants addressing theoretical models and observations in all
wavelength ranges will provide an updated overview of the field. The conference
will last five days (including a free afternoon) and will consist of sessions
with invited and contributed talks and poster. Sessions will devoted to: (a) PMS
objects: circumstellar (protoplanetary) disks around protostellar objects, PMS
stars and Vega-type stars (b) Planetesimals in PMS and MS stellar systems (c)
Planets around stars (d) Searches for planets (e) Impact on planetary system
