12/30/92: ROBOT AND TEAM BEGIN VOLCANO ASCENT, TEAM FEEDS LIVE VIDEO
Charles Redmond
Goddard Space Flight Center, Greenbelt, Md. Dec. 29, 1992
DANTE ADVISORY
The first live video from the Mt. Erebus team in the Antarctic was sent
via NASA's Tracking and Data Relay Satellite last night during a
telecommunications test between team members on the ice at the foot of the
11,000- foot tall volcanic mountain to robotics team members at the Goddard
Space Flight Center in Greenbelt, Md.
Team members had arrived at the base of the volcano Sunday and are in the
process of hauling equipment and the 8-legged, 12-foot tall robot Dante and its
mobile carrier Geryon up the face of the mountain to the volcano crater rim.
The video test included previously recorded hand-held video the team took of
their base camp and inspections of the robot. The live feed showed a
wind-driven snowy scene with flags at the base camp being blown rigidly
straight in the high winds.
The Erebus team expects to feed more taped video today during a TDRS link
at 3:45 pm EST. Today's video communications could last 70 minutes. Some
complications arose during an earlier attempt to feed video yesterday but were
resolved by the time the second test began at 5:30 pm EST. If similar problems
arise during today's primary test period, a backup communications test is
scheduled at 5:50 pm EST and would last through 6:35 pm EST.
Similar primary and backup video telecommunications tests have been set up
for Wednesday, Dec. 30, at 3:30 pm EST and 5:25 pm EST for periods of about an
hour. The tests are being used to verify video transmission capabilities from
the Antarctic to Goddard.
The tests are part of preparations for the descent of the Dante robot down
the inner slope of Mt. Erebus, now set to begin on Thursday, Dec. 31. Local
weather in the Antarctic has caused some delays to the team's original schedule
and certain tasks are taking longer than anticipated. The ascent up the 11,000
foot slope to the rim of the volcano, for instance, was originally expected to
be completed in two days. The team now expects to have all their gear and the
robot in place in three days.
TEAM MEMBERS AND ALL EQUIPMENT IN GOOD SHAPE
Other than weather-induced problems and readjustments to their timetable,
all team members are reported to be in good shape and all their equipment, from
the robot to the telecommunications and computers necessary for the experiment,
have been tested and are in working order.
Should the team be prepared for the operations portion of the
demonstration project on Thursday, the video feeds are expected to originate
from the video navigation cameras mounted on top of the Dante robot. These
live feeds would show the robot's point of view as it navigates slowly down the
steep inner slope of the volcano. Thursday feed times have been tentatively
set for 12:35 through 1:25 pm EST, 2:10 pm through 3:40 pm, 3:42 pm through
3:57 pm, 4:20 pm through 5:25 pm, 5:50 pm through 6:10 pm, and 7:25 pm through
8:25 pm. During all of these periods, the Erebus team expects to be able to
transmit video from the Dante robot as it navigates its way down the slope to
the lava lake located in the Mt. Erebus crater.
A similar video support schedule at approximately the same Eastern
Standard times is being developed for Friday and Saturday. If all goes
according to current plans, Dante is to spend Friday exploring the lava lake in
the crater floor of Mt. Erebus to provide geophysical and atmospheric chemistry
data about the volcano's outgassing and the composition of the lava lake. The
team expects to have Dante climb back up to the rim on Saturday.
PROJECT IS DEVELOPING FUTURE EXPLORATION CAPABILITIES
NASA and the National Science Foundation are undertaking this
demonstration project to develop technology and telecommunications capabilities
which NASA could use in future explorations of the Moon or Mars and which the
NSF might apply to its ongoing research activities in the Antarctic. Part of
the test involves transferring control of the robot from the Mt. Erebus team to
team members located at a payload control center at Goddard. This portion of
the project will test the "telepresence" capabilities of such robots for future
NASA exploration missions.
The Goddard-based remote-control robot test will be the longest distance
ever for live robotic control and simulates the feedback and timelag which
humans would have with robots located on the Moon. Carnegie-Mellon University
and the New Mexico Institute of Mining and Technology are partners with NASA
and the NSF as robotics and volcano experimenters for this project.
During the descent, lava lake exploration and ascent phases expected to
occur Thursday, Friday and Saturday (Dec. 31, Jan. 1 and 2), NASA will provide
commentary on the robot's progress from robotics and volcano experts located at
Goddard. The television feed and commentary will be available both at the
Goddard news center (in the Visitor Center, Soil Conservation Road) and on NASA
Select Television. (Call 301/286-6397 for recorded update information.)

PAST FLIGHTS FOR HAM RADIO:
On November 28, 1983, STS-9 was launched carrying Mission Specialist Owen
Garriott, Amateur Radio call sign W5LFL, and his ham radio into orbit. For 10
days the Space Shuttle Columbia streaked through the skies, and for the last 7
of those days, hams around the world were sent emotionally into orbit when they
heard Dr. Garriott's voice break their squelches calling Earth-bound stations.
But it was just the beginning. Amateur Radio had moved into its newest
frontier, and it was there to stay.

TWO-LINE ELEMENTS FILE INFORMATION
[Editorial Note about Two-line Elements Files:
Two line element data is provided as a public service to those parties
interested in satellite tracking. The data is obtained with permission
of the compiler and is posted on NASA Spacelink without modification
because a number of tracking programs require an exact file format.
During a mission, current orbital elements for the Shuttle are found
on that mission's menu within NASA Spacelink. A quick way to get to
that section is to use the GOTO function and enter a keyword of the
mission number (i.e. STS-45).
The compiler of the two-line elements file offer the following explanation
of how elements are obtained and the format of the file:]
As a service to the satellite user community, the following description of the
NORAD two-line orbital element set format is uploaded to sci.space and
rec.radio.amateur.misc on a monthly basis. The most current orbital elements
from the NORAD two-line element sets are carried on the Celestial BBS, (513)
427-0674, and are updated several times weekly. Documentation and tracking
software are also available on this system. The Celestial BBS may be accessed
24 hours/day at 300, 1200, 2400, 4800, or 9600 bps using 8 data bits, 1 stop
bit, no parity. In addition, element sets (updated weekly) and some
documentation and software are also available via anonymous ftp from
archive.afit.af.mil (129.92.1.66) in the directory pub/space.
==============================================================================
Data for each satellite consists of three lines in the following format:
AAAAAAAAAAA
1 NNNNNU NNNNNAAA NNNNN.NNNNNNNN +.NNNNNNNN +NNNNN-N +NNNNN-N N NNNNN
2 NNNNN NNN.NNNN NNN.NNNN NNNNNNN NNN.NNNN NNN.NNNN NN.NNNNNNNNNNNNNN
Line 0 is a eleven-character name.
Lines 1 and 2 are the standard Two-Line Orbital Element Set Format identical
to that used by NORAD and NASA. The format description is:

GALILEO MISSION DIRECTOR STATUS REPORT
POST-LAUNCH
December 4 - 10, 1992
SPACECRAFT
1. On December 4, real-time commands were sent to change the telemetry rate
from 115.2 kbps to 28.8 kbps so that DSS-12 (Goldstone 34 meter antenna)
could process downlink telemetry. This change was necessary when ground
station problems at DSS-14 (Goldstone 70 meter antenna) caused the Project
to request tracking support at DSS-12. The spacecraft telemetry rate under
stored sequence control was switched back to 115.2 kbps after DSS-12 tracking
support ended. Upon completion of commanding, the CDS (Command Data
Subsystem) command lock counter had increased by 4 which was 2 more than
expected. No unplanned commands were received/processed by the spacecraft.
Analysis of this incident is in progress.
2. On December 4, Part 1 of the EE-11 Earth encounter sequence memory load
was uplinked to the spacecraft without incident. Part 2 of the EE-11 Earth
encounter sequence memory load was uplinked on December 7. This sequence
covers spacecraft activities from December 7, 1992 to December 28, 1992 and
includes the Earth closest approach on December 8, 1992.
The December 7 EE-11 uplink was delayed for approximately 45 minutes
while the ground station transmitter configuration was changed from 18kw with
4db command modulation suppression to 5.5kw with 0.5db command modulation
suppression to eliminate command feedthru degradation of downlink telemetry.
3. During this reporting period, numerous science instrument
calibration/characterization activities were performed to take advantage of
the high telemetry data rates while close to the Earth. Activities included
Magnetometer (MAG) scan platform interference test, Solid State Imaging (SSI)
boomscatter test, and a MAG calibration coil. All calibration/characterization
activities were performed nominally and data analysis is in progress.
4. On December 5, real-time commands were sent to update the gyro drift
parameters using spacecraft gyro data collected on November 29. This update
was performed to meet the scan platform pointing requirements in support
of Earth 2 science data collection when the star scanner shutter was closed.
5. On December 5, real-time commands were sent to disable the AACS (Attitude
and Articulation Control Subsystem) sun-dependent algorithms and enable the
AACS bright body fault protection in preparation for the Earth 2 flyby. The
commands executed nominally on the spacecraft prior to the start of the EE-11
Earth encounter sequence.
6. On December 5 and 6, NO-OP commands were sent to reset the command loss
timer to 72 hours, its planned value during this mission phase.
7. On December 8, Earth closest approach occurred at 7:09:25 AM PST at an
altitude of 303.1 km. The Earth Gravity Assist (EGA) was performed flawlessly.
During the Earth closest approach time period, the Galileo spacecraft took
observations of the magnetosphere, Moon and Earth system.
8. On December 8, approximately three hours after closest approach, real-time
commands were sent to enable the AACS attitude control sun dependent
algorithms to their nominal post fly-by state. Also, the command loss timer
was reset to 11 days in accordance with the EE-11 sequence strategy.
9. On December 8, real-time commands were sent to update the attitude control
bright body vector in the EE-11 Earth encounter sequence to permit star set
acquisition for the December 10 stored-sequence SITURN.
10. On December 8, after approximately 8 hours after closest approach,
real-time commands were sent at PI (Principal Investigator's) request to turn
off the Energetic Particle Detector (EPD) LEMMS-A detector bias.
11. On December 9, the Galileo Optical Communications Experiment from an
Earth-based Xmitter (GOPEX) experiment began. This experiment consists of
pulsing a laser at the Galileo spacecraft from the Table Mountain Observatory
(TMO) and the Starfire Optical Range (SOR). The Solid State Imaging (SSI)
camera is shuttered while slewing across the Earth resulting in a series of
illuminated pixels in the image. The experiment is continuing at the writing
of this report. Preliminary analysis of the data is in progress.
12. On December 10, the spacecraft executed an 11-degree SITURN. The main
purpose of the SITURN was to maintain the spacecraft within plus or minus 10
degrees of the sun at the current solar distance.
13. The AC/DC bus imbalance measurements exhibited some change. The AC
measurement has ranged from 16DN to 17DN and now reads 17DN (3.9 volts).
The DC measurement has ranged from 115DN (13.4 volts) to 148DN (17.4 volts)
and now reads 132DN (15.5 volts). These measurement variations are consistent
with the model developed by the AC/DC special anomaly team.
14. The Spacecraft status as of December 10, 1992, is as follows:
a) System Power Margin - 59 watts
b) Spin Configuration - Dual-Spin
c) Spin Rate/Sensor - 3.15rpm/Star Scanner
d) Spacecraft Attitude is approximately 4 degree
off-sun (leading) and 95 degrees off-earth (leading)
e) Downlink telemetry rate/antenna-67.2kbps (coded)/LGA-1
f) General Thermal Control - all temperatures within
acceptable range
g) RPM Tank Pressures - all within acceptable range
h) Orbiter Science- all instruments are powered on
except the PPR
i) Probe/RRH - powered off, temperatures within
acceptable range
j) CMD Loss Timer Setting - 264 hours
Time To Initiation - 215 hours
TRAJECTORY
As of noon Thursday, December 10, 1992, the Galileo Spacecraft trajectory
status was as follows:
Distance from Earth 1,583,900 km (.01 AU)
Distance from Sun 147,088,200 km (0.98 AU)
Heliocentric Speed 140,500 km per hour
Distance from Jupiter 857,457,800 km
Round Trip Light Time 0 minutes, 12 seconds
SPECIAL TOPIC
1. As of December 10, 1992, a total of 8786 real-time commands have been
transmitted to Galileo since Launch. Of these, 3753 were initiated in the
sequence design process and 5033 initiated in the real-time command process.
In the past week, 74 real time commands were transmitted: 72 were initiated
in the sequence design process and 2 initiated in the real time command
process. Major command activities this week included commands to change the
telemetry rate, uplink the EE-11 Earth encounter sequence memory load, update
gyro drift parameters, disable sun-dependent algorithms, enable bright body
fault protection, reset the command loss timer, enable the sun-dependent
algorithms, update the bright body vector, and turn the EPD detector bias off.
2. Intermittent telemetry has been observed since Earth closest approach as
a result of a 6db variation in signal levels received at the tracking stations.
The causes for these variations is presently unknown, but is likely the result
of spacecraft boom/structural interference, high telecom cone angles
(>110 degrees) and possibly RF leakage from LGA-2 (Low Gain Antenna #2).
After the SITURN on December 10, the cone angle was approximately 95 degrees
and the ground received signal variations and data degradations were
considerably reduced. Analysis of the trajectory and the stored-sequence
planned SITURN indicates that the cone angle will not again reach 100 degrees.
A stored-sequence SITURN on December 16, prior to the Earth/Moon conjunction
playback, will further reduce the cone angle to less than 85 degrees. At cone
angels less than 85 degrees no boom/structural interferences is possible;
correspondingly telecommunication performance is expected to further improve.

This view of the north polar region of the Moon was obtained by
Galileo's camera during the spacecraft's flyby of the Earth-Moon
system on December 7 and 8, 1992. The north pole is to the lower
right of the image. The view in the upper left is toward the
horizon across the volcanic lava plains of Mare Imbrium. The
prominent crater with the central peak is Pythagoras, an impact
crater some 130 kilometers (80 miles) in diameter. The image was
taken at a distance of 121,000 kilometers (75,000 miles) from the
Moon throught the violet filter of Galileo's imaging system.
According to the team scientists, the viewing geometry provided by
the spacecraft's pass over the north pole and the low sun-angle
illumination provide a unique opportunity to assess the geologic
relationships among the smooth plains, cratered terrain and
impact ejecta deposits in this region of the Moon. JPL manages
the Galileo Project for NASA's Office of Space Science and
Applications.

This mosaic picture of the Moon was compiled from 18 images taken
with a green filter by Galileo's imaging system during the
spacecraft's flyby on December 7, 1992, some 11 hours before its
Earth flyby at 1509 UTC (7:09 a.m. Pacific Standard Time)
December 8. The north polar region is near the top part of the
mosaic, which also shows Mare Imbrium, the dark area on the left;
Mare Serenitatis at center; and Mare Crisium, the circular dark
area to the right. Bright crater rim and ray deposits are from
Copernicus, an impact crater 96 kilometers (60 miles) in
diameter. Computer processing has exaggerated the brightness of
poorly illuminated features near the day/night terminator in the
polar regions, giving a false impression of high reflectivity
there. The digital image processing was done by DLR, the German
aerospace research establishment near Munich, an international
collaborator in the Galileo mission. The Galileo project, whose
primary mission is the exploration of the Jupiter system in 1995-
97, is managed for NASA's Office of Space Science and
Applications by the Jet Propulsion Laboratory.

This false-color mosaic was constructed from a series of 53
images taken through three spectral filters by Galileo's imaging
system as the spacecraft flew over the northern regions of the
Moon on December 7, 1992. The part of the Moon visible from
Earth is on the left side in this view. The color mosaic shows
compositional variations in parts of the Moon's northern
hemisphere. Bright pinkish areas are highlands materials, such
as those surrounding the oval lava-filled Crisium impact basin
toward the bottom of the picture. Blue to orange shades indicate
volcanic lava flows. To the left of Crisium, the dark blue Mare
Tranquillitatis is richer in titanium than the green and orange
maria above it. Thin mineral-rich soils associated with
relatively recent impacts are represented by light blue colors;
the youngest craters have prominent blue rays extending from
them. The Galileo project, whose primary mission is the
exploration of the Jupiter system in 1995-97, is managed for
NASA's Office of Space Science and Applications by the Jet
Propulsion Laboratory.

This color image of North-East Africa and Arabia was taken from
an altitude of about 500,000 kilometers (300,000 miles) by the
Galileo spacecraft on December 9, 1992, as it left the Earth enroute
to Jupiter. Most of Egypt (center left) including the Nile
Valley, the Red Sea (slightly above center), Israel, Jordan, and
the Arabian peninsula are cloud-free. In the center, below the
cloud on the coast, is Khartoum, at the confluence of the Blue
Nile and the White Nile. Somalia (lower right) is partly cloud-
covered. The Galileo project, whose primary mission is the
exploration of the Jupiter system in 1995-97, is managed for
