Here's a start on what I've gotten since I started in. I'm a student teacher
here in Texas. I am hoping to use some of this with my students, and I
couldn't pass you by when you weren't getting the info. There'll be a second
letter too since I couldn't get it all in this one. I took out the air and
forwarded the cream, but if you need the whole thing, just let me know.

Information last updated: August 29, 1996
Welcome to the Live from Mars mail list. Live from Mars is a K-12 education
project to connect students and teachers with the exciting missions to Mars.
We will focus on the people involved and what they do. This list will be
used to share information about Live from Mars as it evolves. As well,
we will distribute Field Journals from the diverse men and women who make
modern space research possible. The majority of activity will begin in
mid-September of 1996.
An overview of Live from Mars follows:
In 1996 NASA will launch two missions to Mars. The Mars Global Surveyor
spacecraft will launch in November and will arrive about 9 months later
to begin an orbital mission which will provide detailed mapping and weather
information. The Mars Pathfinder spacecraft will launch in December and will
land on the Red Planet on July 4, 1997. Once landed, the mission plan calls
for a micro-rover named Sojourner to begin wondering the Martian terrain,
returning a wealth of new science data.
By participating in Live from Mars, you and your students can travel along!
The project is targeted at the middle school grade levels, but will have
appeal above and below that range.
Four live telecasts from this scientific frontier are scheduled between
November 1996 and November of 1997. Plans are also underway for a training
tape to assist integration of this project into classrooms, home schools,
and lifelong learning. Live telecast air dates of first two programs are:
Tuesday November 19, 1996, 13:00-14:00 ET, and
Thursday April 24, 1997, 13:00-14:00 ET
Mission exigencies *may* result in changing one or more of these dates. But
we hope not! These programs will be broadcast nationally via satellite in the
United States by NASA TV and PBS However, local PBS stations may or may
not decide to carry the programming; please consider contacting your local
PBS station to express your interest in this program.
Exceptional hands-on curriculum materials are being developed and will be
available in late September in a Teachers' Guide. This Guide will be
distributed online for free. As well, a printed version will be available
for $10. And a multimedia kit will be available for $99. This kit will
include the printed Teachers' Guide, an original color poster, a teacher
orientation videotape, slide sets, a Mars Navigator CD-ROM -- and more!
To order either of these optins, send a check made out to Passport to
Knowledge
to PTK, PO Box 1502, Summit, NJ 07902-1502, USA. Schools and other
institutions may submit Purchase Orders.
In addition, online resources will include rich and varied web pages,
extensive email information and interaction, discussion groups and
"Researcher Q and A "and "Field Journals". Our web site is in
"continuous construction" mode, but already some information is available.
Please visit http://quest.arc.nasa.gov/mars
As well, a discussion list for teachers participating in the project
is available. Here you can meet other teachers involved in implementing
Live From Mars in their classrooms. Together you can ideas, solving problems
and collaborate to best utilize the unique Live From Mars project.
To join this discussion, tune in on the Web (look in the Teachers' Lounge)
or particiapte via email by sending a note to: listmanager@quest.arc.nasa.gov
In the message body, write these words: subscribe discuss-lfm.
Each video and accompanying online and print materials will allow
educators to customize the learning experience, whether they use only one
program, live or on tape, or follow the Mars missions across the school
years.
As with all Passport to Knowledge projects, Live from Mars will make the
human dimension of contemporary science and high tech careers come to life.
Curriculum strands include: Mars geology and evolution as a planet, robotics,
interplanetary weather, exobiology, mission planning, rocketry, comparisons
between planets of the solar system, and Mars imaging resources.
Live from Mars is a collaboration between Passport to Knowledge, the Mars
Exploration Directorate of NASA's Jet Propulsion Laboratory, and the NASA
K-12 Internet Initiative. Passport to Knwoledge is supported in part
by NASA, the National Science Foundation, PBS Teacher Resource Services,
and public television.

UPDATE # 1 - August 3, 1996
PART 1: Welcome to the project
PART 2: Why you got this mail message
PART 3: Status of the spacecraft
______________________________________________________________________
Welcome to "LIVE FROM MARS", a project developed by
the Passport to Knowledge team.
Over the next year, you will receive a unique perspective on
NASA's robot missions to Mars. Through this maillist, you will
receive regular Field Journals from the men and women who are
responsible for flying two spacecraft (Mars Global Surveyor and
Mars Pathfinder) to the red planet. You will hear from the space
researchers preparing for the exciting new knowledge which will be
gained from the Martian missions. Also, a variety of other Mars-workers
not directly connected to the two missions will share their perspectives.
These behind-the-scenes reports will a glimpse of the day-to-day
activities required, including the broad diversity of skills needed as we
enter an unprecedented decade of Mars exploration.
LIVE FROM MARS (LFM) includes several live television programs.
The first two are scheduled for November 19, 1996 and April 24, 1997 from
1-2 PM Eastern time (It is not too early to contact your local PBS station
to encourage them to carry the programs). As well, a detailed Teacher's Guide
will be available in about one month. This document will detail a variety of
hands-on science activities designed to integrate with the online and
television resources. More information about this teachers guide will be
shared here over the next few weeks, including availability information.
A dedicated online archive is rapidly coming together. It includes the
complete collection of Field Journals, biographies of Mars people,
an image gallery, a collection of classroom projects and much more.
This "continuous construction" Web site will be found at
http://quest.arc.nasa.gov/mars and is expected to be made public
in one month.
As LFM evolves, special activities will be scheduled. For example,
we'll conduct a collaborative activity about designing instrument packages to
analyze local environments. After some classroom work, students will debate
their ideas and determine a standardized package. Then these packages will be
used to make actual measurements which will be shared globally. A series of
special WebChat and CU-SeeMe sessions with Mars folks will be scheduled.
As details emerge they will be announced on this updates-lfm mailing list.
Presently, we plan to publish these email updates about twice per month.
The frequency will increase as the school year starts and the missions get
closer to launching in November.
Throughout the LIVE FROM MARS project, our team will be interested
in receiving your ideas and feedback. Send any comments to Jan Wee
(janw@quest.arc.nasa.gov) or to Marc Siegel (marc@quest.arc.nasa.gov).
We hope that LIVE FROM MARS will prove to be an exciting learning
resource for you and your students.
Thanks for your interest,
Marc

Mars Pathfinder Status
Tony Spear
May 1, 1996
The fully assembled Mars Pathfinder flight system has just successfully
completed an "acoustic vibration" test which uses sound waves to simulate
the launch environment. It is also being readied for what is called a
thermal/vacuum test: we put the flight system into a large 25 foot chamber
and pump the air out of the chamber to simulate the vacuum of space in
cruise, while shining infrared lights on the flight system to simulate the
intense sunlight in interplanetary space.
After this test, we put the flight system into its surface configuration
with the lander open and the rover off the lander, communicating with the
lander through its radio link. We again pump down the chamber, but this
time to Mars surface atmospheric pressure and cycle the flight system through
hot and cold temperatures to simulate Mars day and night cycles.
Before, during and after each of these cruise and surface environmental
tests, we do system electrical testing of the flight system to ensure the
proper operation of all the systems. After all of this, in August, we
partially disassemble the flight system to ship it to the Eastern Test
Range in Florida for launch preparations.
All is going well for launch on December 2, 1996!
Mars Global Surveyor Status
Glenn E. Cunningham
May 1, 1996
All activities of the Mars Global Surveyor (MGS) project are moving along
well toward launch in early November.
The spacecraft assembly is nearly complete at the Lockheed Martin facility in
Denver, Colorado, and has the spacecraft has begun its first fully integrated
system electrical testing. All but two of the science instruments have been
installed, and the remaining ones are due in May.
As is the case with many spacecraft, the mass of the assembled hardware
always seems to be a little more than is predicted by the design documents.
Such is the case with the MGS spacecraft. A considerable effort has been
applied by the project team over the last few months to reduce the
spacecraft mass and to find ways to change the mission plan to be able to
accept a little heavier spacecraft and still be able to meet mission
objectives. After all the studies were complete, and the mass of the all
the spacecraft assemblies had been reassessed, we agreed on a 1060-kg
upper limit total launch mass and slipped the opening of the launch period
one day to open on November 6th. Some of the spacecraft's thermal blankets
are the only remaining items yet to be weighed, but all indications are
good that the mass limit will be met.
The end-to-end tests that assure compatibility between the flight
operations system (which will be responsible for "flying" or controlling
the spacecraft after launch) and the spacecraft itself are now underway,
and the results are looking good.
The two remaining science instruments, the Thermal Emission Spectrometer and
the Mars Orbiter Laser Altimeter, suffered minor setbacks during their final
acceptance testing, and both required some reworking before final testing and
delivery. The required rework is underway and is progressing well.

Animals in Mars
Sender: owner-answers-lfm
Precedence: bulk
Before you have any humans living on mars would you have animals tested to
live in it first?
-----
ANSWER from Cheick Diarra on December 20, 1996:
Sending a living being to Mars is so complex and the
technologies are so dependable now I think that after we learn what we need
to know to send a human to Mars, we will not go through the step of sending
animals there.
Cheick.

Dear discuss-lfm members,
Just in case you haven't had time to access the NASA JPL
Mars Pathfinder web site and check on how Mars Pathfinder
is doing, here is the latest update.
Hope everyone had a relaxing break if you were on vacation
over the holidays! We are all looking forward to the start of
our Planet Explorer Toolkit debate which will begin next week
on Monday, Janaury 6th. Thanks to all who have posted their
Planet Explorer Toolkit proposals and yes, even to those of you
who posted after the December 20th deadline. We plan to include
all your ideas (even if you got caught in the holiday rush!)
Welcome back to LFM!

MARS PATHFINDER MISSION STATUS
December 18, 1996
12:00 p.m. Pacific Standard Time
Sojourner, a 10-kilogram (22-pound) rover tucked away on a petal of the
Mars Pathfinder spacecraft, got a 'wake up' call on Dec. 17 from flight
controllers at NASA's Jet Propulsion Laboratory. After waking up, Sojourner
conducted an internal health check and sent data back to the flight team
that all was well.
The Pathfinder flight team was ecstatic with the rover data, which
showed that all systems within the rover were operating normally. In
addition, data from the rover's main science instrument -- the alpha
proton x-ray spectrometer -- showed that it was operting properly.
"The rover woke up, did its internal health check, sent the lander
its status data and went back to sleep, all as planned," said
Art Thompson, rover operations team member. "All subsystems were
verified as being in good health."
Pathfinder continues to perform very well on its 500 million-kilometer
(310 million-mile) journey to Mars, the team reported. Currently the
spacecraft is 4 million kilometers (2.5 million miles) from Earth, traveling
at a speed of 3.1 kilometers per second (7,000 miles per hour). Its
destination, Mars, is currently about 190 million kilometers (118 million
miles)away. All temperatures and power utilization of the lander and cruise
stage remain at their predicted levels for this phase of the mission.
The spacecraft was spun down from 12.3 rpm to 2 rpm on Dec. 11. Flight
controllers first instructed the spacecraft to turn to a Sun angle of
50 degrees and an Earth angle of 32 degrees. This allowed them to use
all four operating Sun sensors. The spacecraft executed the commanded
spin down to the normal cruise spin rate of 2 rpm in steps of 2 rpm
at a time.
Once the normal spin rate was established, the team turned on the
spacecraft's star scanner on Dec. 12. Star scanner data allows the
spacecraft to establish full, three-axis knowledge of its orientation
in space. This is the normal cruise attitude control mode and the
one in which all trajectory correction maneuvers will be performed.
While Sun sensor #5 continues to work well after a software fix, the
flight team continues to investigate the cause of the loss of Sun sensor
head #4. The team expects to reach a likely conclusion on the cause of
the problem within the next month or two.
Dave Gruel, Pathfinder flight director at JPL, conducted the Dec.16
health check of the lander science instruments, including the atmospheric
sensor instrument and meteorology (ASI/MET) package and the imager.
Temperature, pressure and accelerometer readings from the
atmospheric/meteorology
instrument verified it was in normal working order. Power and dark current
measurements received from the imager while it was imaging the darkness
around it, confirmed that the instrument was working properly, Gruel said.
Richard Cook, Pathfinder mission operations manager at JPL, reported
today that Pathfinder has been fully checked out for this phase of
the mission and that all subsystems are "go" for a successful seven-month
cruise to Mars.
The next major in-flight event will be Pathfinder's first trajectory
correction maneuver, which is scheduled for Jan. 4, 1997.
