November 3, 1998
John McNamee
Mars Surveyor 98 Project Manager
Mars Climate Orbiter: Launch -37 days
Flight software build 8.2.1 was loaded on the orbiter and the star
camera portion of the Attitude Control System (ACS) phasing test was
completed successfully. The reaction wheel phasing is scheduled for
completion tommorrow.
Mars Polar Lander: Launch -61 days
The Deep Space Network (DSN) End-to-End compatibility test was completed
with no spacecraft issues and no significant ground configuration issues.

Deep Space 1 Mission Status
November 4, 1998
Deep Space 1 continues to perform extremely well, according
to spacecraft engineers at NASA's Jet Propulsion Laboratory.
On Friday, October 30, the spacecraft successfully executed
a large turn to point the ion engine toward the Sun. Sunlight
heated portions of the xenon feed system and the ion thruster
core (which reached about 110 degrees C or 230 degrees F) and
baked off some contaminants that might interfere with the
engine's operation. While the spacecraft remained in that
orientation, a small amount of xenon from the ion propulsion
system was allowed to flow through the system to assure that
there were no blockages. The spacecraft returned to its previous
orientation on Saturday. The operations team then conducted the
first of two activities involving the pair of Solar Concentrator
Array with Refractive Linear Element Technology (SCARLET) solar
arrays, provided to NASA by the Ballistic Missile Defense
Organization, Washington D.C., and built by AEC-Able Engineering
Company, Inc., Goleta, CA. This involved measuring the arrays'
electrical characteristics, particularly eight modules comprised
of five solar cells each that are specially instrumented for
measuring current and voltage. Originally scheduled for November
1, this activity was completed ahead of schedule on October 31.
The second, more complex characterization of the solar
arrays was executed successfully in a 10-hour activity on
November 1. The intricate choreography included rotations of the
pair of solar arrays and turns of the spacecraft to vary the
angle of the sunlight incident upon the arrays, all designed to
determine the best angle to maximize collection of sunlight. The
analysis of the large volume of data collected will be conducted
over the next several days.
On November 2, at approximately 8 p.m. PST, the team noted
that the orientation of the spacecraft changed briefly for
reasons that are under investigation. The spacecraft remained
safe throughout this small anomaly, which the spacecraft self-
corrected quickly using its attitude control and fault protection
systems.
Most activities this week are geared toward preparing the
ion system for the first test of thrusting, currently planned for
November 9 at the earliest. These include turning on a heater
inside the thruster's cathode and pressurizing the xenon system,
both scheduled for Thursday, November 5. After testiing planned
for November 9 and 11, the engine is scheduled to be used for
thrusting beginning no earlier than November 23. DS1 is now more
than five times farther away from Earth than the moon.

CALTECH MANAGEMENT ASSOCIATION
presents
"APOLLO: An Eyewitness Account"
with
Alan Bean
Astronaut / Explorer Artist / Moonwalker
Date: Thursday, November 12
Time: 4:30 p.m. Book-signing in the museum
5:00 p.m. Presentation with slides
5:45 p.m. More book signing and discussion
Place: von Karman Auditorium and museum
Jet Propulsion Lab
4800 Oak Grove Drive
Pasadena, California
THIS EVENT IS OPEN TO THE PUBLIC
NASA has often been asked, "Why not send an artist to the moon?" Well, it
turns out NASA has. Accomplished painter and astronaut Alan Bean has worked
since his return to Earth 29 years ago to portray the intensity and beauty
of the world he visited. His new book, "Apollo: An Eyewitness Account,"
contains over 90 of his fine-art paintings depicting the lunar experience
in a completely novel and inspirational way. At our CMA event, Alan Bean
will show slides of these paintings while offering an insider's view of the
Apollo missions.
Bean's career in space continued to soar after the lunar landing. He served
NASA as Mission Commander of Skylab II, the United States first space
station, and spent 59 days in orbit. He also was backup commander of the
Apollo-Soyuz Test Project in 1975, and then was assigned as Chief of
Operations and Training and Acting Chief Astronaut until the flight of the
first space shuttle.
Since leaving NASA in 1981, Bean has focused on another mission. As Actor
Tom Hanks says, "In the realm of the arts, it has fallen upon Al Bean to be
the one moonwalker to turn the data brought back from the moon into
something other than numbered photographs." Bean takes pride in his ability
to depict what no other painter has seen, and feels the responsibility
inherent in that distinction.
Come join us in von Karman Auditorium to hear Alan Bean share his unique
point of view of the space frontier. He will be in the museum before and
after the talk to sign copies of his book, "Apollo: An Eyewitness Account
by Astronaut/Explorer Artist/Moonwalker Alan Bean." The book also has text
by Andrew Chaikin, author of A Man on the Moon, the basis for Tom Hanks'
12-part HBO Apollo series.
ERC will be selling copies of the book at the event for $35.00.
