Exercises include: (1) modeling the surface using the maps and
"rock" files, (2) making qualitative estimates of the
strengths of the "soils or dirts" at the landing sites, and
(3) interpreting Viking lander images. In one exercise,
students locate "Mr. Toad" (of Wind in the Willows fame) in
images and on a map. Maps, images, and instructions are
provided for the exercises.
The exercises are structured so that they can be used by a
broad range of students.
Reports on Mars science, exploration, and education topics,
and major outreach programs by Jim Tillman, former member of
the Viking Meteorology Science team and Pathfinder Flight
Team.
"Viking View of Mars" Permanent exhibit
at the Smithsonian National Air and Space Museum,
Washington, D.C.
As a consequence of developing the "real time"
downlink processing infrastructure at the Viking
Computer Facility, Tillman initiated this permanent
exhibit which was developed by his staff and The
Center for Earth and Planetary Sciences at the
Museum. Opertion was tested in September, 1982, and
raw spacecraft bits were decoded in real time.
Processed meteorology data and images were displayed
in the museum within 5 minutes of the downlink from
Mars and during normal operation, images were to be
delivered line by line in real time. A super-mini
computer was obtained by donation for the exhibit
which was initially titled "Live from
Mars"; this was the first computer driven
exhibit at the museum.
This Java application, created by volunteer George LeCompte,
permits the selection of objects and their features from
Viking Lander 2 stereo image pairs and indicates their
location on a diagram of the lander site. It presently has one
image that includes "Mr. Toad" and more will be added.
Pioneering low cost planetary mission
operations at UW, which enabled the last
half of Lander 1's operation, is described in a 1984
paper "The Viking Mission to Mars", and other
accomplishments of Tillman's Viking Computer Facility
staff at UW. This includes "real time" decoding and
processing of engineering, meteorology and image data
from raw spacecraft bits. Highlights of Viking and
Mars exploration are included
The 3.3 year Martian climate record,
from July 20, 1976, through November 12, 1982, as
represented by the Atmospheric Pressure observations
from the two Viking landers, is plotted and briefly
annotated. The major characteristics of the Martian
atmosphere, such as great dust storms, atmospheric
oscillations, fronts, and the annual pressure cycle,
are identified. These classical plots and notes are of
most interest to scientists, although others may want
to use them to illustrate the atmospheres annual
condensation-sublimation cycle, the seasons, fronts
and dust storms. Other meteorological data,
information and writeups of more general interest will
be included in the future.
"Liquid water is an essential requirement for life, and liquid
water serves as a kind of surrogate indicator for biological
activity. The element iron interacts strongly with liquid
water, especially with water in which gases like CO2 and O2
are dissolved."
"Therefore: The history of water on Mars is reflected in the
iron mineralogy of the Martian soil, a soil colored red by
Fe3+-compounds. Fe3+-ions are essential ingredients in all
naturally occurring magnetic compounds. From the brief
description given below it will become apparent that the
investigation of the magnetic phase in the Martian soil is
strongly coupled to the study of the history of water on the
surface of the planet.'
Magnetic Properties of soils experiments and the water
history of Mars, The Mars Group, Niels Bohr Institute, is
carrying out a number of experiments to determine the magnetic
properties of the Martian soils. Magnets are placed on the
lander at several locations, (some of varying strengths), and
photographed by the Imager
For Mars Pathfinder (IMP), addressing several major
scientific questions. For example,
K-12 programs containing useful ideas, information,
or lessons are referenced here.

SUPPORT
Digital Equipment Corporation, (now
Compac) support in providing DEC Alpha
workstations is greatly appreciated. These major computational
resources provided a key components for the development and
distribution of our "Live from Earth and Mars" K-12 science
education program, the server and display for the "Where Next,
Columbus" exhibit at the Smithsonian National Air and Space
Museum, Washington D. C., and processing of the Pathfinder data for
distribution worldwide to schools and the public "Live from
Mars" during the NASA Pathfinder Mission to Mars.
