Pictures may be seen at planetarium
, From Staff and Wire Reports
The eerie and often amazingly beautiful sights
of the ringed planet Saturn will again reveal them
selves to the world this week as the Voyager space
probe flies by the planet sending pictures back to
earth, including those to be received by the More
head Planetarium on campus.
As the spaceship cruises past the solar system's
second largest planet this week, the planetarium
will offer students and area residents a series of its
live transmissions, planetarium Director Tony
The probe, now nearly a billion miles from earth,
has been sending back pictures of the planet, its
massive ring structure and its many moons for sev
eral days. But the transmissions relayed this week
will give the closest view of the secrets of Saturn,
Jenzano said Tuesday's program, which starts at
8 p.m., would be a special program because the
craft will be passing through the planets E-ring at
its closest point to the planet. When Voyager 2
passes through the E-ring, it will be at a crucial
stage in its mission because it may encounter chunks
of matter and become damaged, Jenzano said.
Monitors on earth would not know of the probe's
condition until midnight .Tuesday, when a two-and-a-half
hour blackout is lifted on transmissions
from Voyager 2.
The programs, replacing the planetarium's regu
larly scheduled shows, will run today through Fri
day and will be free to the public. They will begin
at 8 p.m. every night and last approximately one
hour, except during Tuesday's special transmission,
which will precede the craft's entering the blackout
Jenzano stressed that there would be no compar
able event until 1986, when Voyager 2 reaches Ura
nus, the next planet out from Saturn in the solar
system. " ,
The planetarium also had the live broadcasts for
the flyby of Voyager 1 , and more than 2,500 people
saw those pictures as they were relayed from deep
space. This time, however, fewer, spectators arefex-

The transmissions from Voyager 2, relayed from
space to special networks in California, are seen at
the planetarium at the same time they are seen by
scientists and researchers around the country,
some of whom will provide commentary.
Meanwhile, researchers were busy this weekend
collecting photographs and transmissions from
Voyager 2 and making new discoveries about the
ringed planet-.. , , r .
For instance, a close-up look by Voyager 2 at
Saturn's strange twb-toned moon gave no obvious
explanation of why half its surface is some of the
darkest material in the solar system and the rest is a
shiny sheet of cratered ice, scientists said Sunday.
The initial examinations of photos taken as Voy
ager passed within 560,000 miles of the moon Iape
tus late Saturday did not solve the riddle, although
much more extensive study should at least give solid
hints, said Bradford A. Smith, photography team
. "It's not something that's coming right out and
staring us in the face," he said at a news conference.
The ship, closing within 1.5 million miles of Sa
turn's swirling cloudtops. Sunday, also aimed its
cameras and instruments at the moons Dione, Titan,
Rhea, Hyperion and Mimas. It examined the com
plex structure of the planet's fabled rings and
watched the ribbons, pinwheels, belts and spots
churning about the gold-orange clouds.
The ship was on target and in good shape as it
approached Tuesday night's rendezvous with the
giant, gaseous planet. ,
Smith said Iapetus seems to be covered with a
skin of ice over a rocky interior. So "probably the
bright material is what should be there and the dark
material is coming from somewhere else," he said.
-The key question is whether the dark covering
oozed out from inside the moon or came from but
side the moon and was splattered across its forward
face, he said. ,. '
Smith said the dark area "appears to be quite a
bit darker than asphalt ... and is twice as dark as
the very, darkest region of Earth's moon but that
doesn't tell us where it came from." -"
He said some types of asteroids are about as dark.
Voyager also is examining selected areas with the
rings, a startlingly complex collection of particles
that range in size from dust to boulders, to search
for moonlets embedded in the rings. Any such
moons, which might be anywhere from half a mile
to 20 miles across, might explain why the rings are
. separated into hundreds of ringlets.
Chief Voyager scientist Edward Stone said, "a
little moonlet buried in the rings ... will form a
gap" by sweeping particles out of its orbit.
Voyager is concentrating its search on a specific
gap several hundred miles wide, where. if the
moonlet theory is correct an icy boulder 12 to 18
miles across should be located, Stone said.
Smith said the search is about one-third complete
and that "we have yet to detect one of these em-',
The1 comprehensive search will continue as
Voyager races toward its rendezvous with the pla
net, collecting photos of eight other moons along
the way as it leaves Saturn behind.
Tugged by the planet's gravitational pull,
Voyager's speed climbed to 27,000 mph Sunday. It
will be sailing along at more than 54,000 mph by
the time it passes Saturn and curves off for a pass
by distant Uranus in January 1986.
The one-ton spaceship was on target and healthy,
said mission director Richard Laeser, and "opera
tions for the last 24 hours have been routine,"
Smith displayed photos their colors falsified
, by juggling wave lengths to increase detail that
showed "increasing evidence for vorticity in Sa
An oval clump of clouds seemed to be rotating
clockwise where it is trapped between two jet
: streams that race in opposite directions across the
The feature, which appears bluish against a field
of brown clouds, may be similar to a gigantic hur
ricane on Earth.
Voyager 2's views of the huge; distant planet are
much more detailed than pictures taken last No
vember when a sister ship, Voyager 1, toured the
The tugging tides could be "flexing and cracking
open the surface so gases can escape" like cham
pagne when a cork is popped. The fog of gas and
water might not only repeatedly cover the surface
but even provide material that forms the broad,
thin E-ring outermost of Saturn's seven major .
"In general, we suspect very strongly it's an
active object, but we'll just have to wait and see';
The hectic close encounter with Saturn will keep
scientists happily overwhelmed as the ship skims
past six major moons, studies seven smaller ones,
closely examines the inexplicably complex structure
of the rings and searches the region for the unex
pected. Results of the trip will be trickling out for weeks'
as scientists sort through some 18,500 pictures.
While approaching Saturn, two Voyager cameras
will look from different angles to obtain a stereo
image of a strange, thin ring that seems to be twisted
into braids. Beginning at 4:42 p.m. Tuesday, Voy
ager will count the hundreds Of ringlets inside the
major rings by watching the light from a star blink
on and off as the spacecraft passes behind the rings.
The ship also will zip past the moon Hyperion
late Monday, then catch giant, haze-obscured Titan
from 413,000 miles at 2:38 a.m. Tuesday.
Voyager, 2, its flight plan altered to examine
many of the mysteries found last year and to look
in places Voyager 1 could not see, is also examining
more closely many of Saturn's 17 known moons.
Tuesday's visit to Saturn also will feature close
encounters with nine of its major moons. Laurence
Soderblom, deputy photography leader and moon
specialist, said the high point should be a flyby of
the smooth globe of Enceladus at 8:45 p.m. PDT, .
21 minutes after the ship buzzes Saturn from 63,000
Since Voyager 2 is nearly a billion miles from
Earth, radioed news of its encounter won't reach
the Jet Propulsion Laboratory here for one hour,
"As far as the possibility of finding something
that's really wild and new, it has got to be Encela
dus," Soderblom said in an interview. "Enceladus
is going to be very exciting."
The moon, he said, is extremely bright, suggest
ing it may be covered with frozen material freshly
painted on its surface. Unlike most other large
Saturnian moons, Enceladus shows few of the
craters caused by bombardment by space debris.
Soderblom said the complex gravitational inter
actions with another moon and Saturn could be
heating the inside of watery Enceladus with tidal
currents, leaving only a thin, frozen crust intact.

JLegislcitoTs find bad
ood m n8W districts
By DEAN LOWMAN
DTH Staff Writer ' ! ;
Area legislators say they have5 mixed
emotions about the N.C. General Assem
bly's Congressional redistricting plan.
The plan, approved by the legislators in
early July, moves Orange County from
the 2nd to the 4th Congressional district,
linking it with Durham and Wake Counties.-.
"The plan has definitely got some prob
lems, because it links a small county
(Orange) with 4wo giants," said Rep.
Trish Hunt, D-Orange.
Sen Charles Vickery, D-Qrange, said a
second problem with the plan was that
"with the area seeing such a tremendous
population growth in recent years, it is
likely that the district will have to be
changed again after the 1990 census."
But both legislators said they felt the
Triangle district may benefit from the
"This will make the area a clear, identi
fiable unit as each county has similar
goals," Vickery said. "The legislator from
this district will place a tremendous em
phasis on education, medical care and the
growth of industry in the Research Tri-
XangleJPark area," hesaid.! V? : r
Hunt said the rnlive should pove worth
while for the citizens of Orange County
. because they "have a lot in common with
people in the other counties and can work
toward the same goals."
Vickery, however, cautioned that his
predictions were dependent upon the
quality of the congressman elected from
the district. ; -
"If you have a good congressman who
works for the people, I think you will see
that the Triangle area will experience a lot
of progress over the next decade. . '
"But if the Triangle's representative
doesn't do a good job, I think we will
look back on this decade with ' regret,"
Other counties affected byjthe redis
tricting plan are Jones County", 'shifted
from the 1 st District to the 3rd; Alamance,
6th to 2nd; Chatham, 4th to 2ndY Ran
dolph, 4th to 6th; and Hoke County, 7th
In addition, Alexander County was
shifted from the 10th District to the 5th;
Davidson, 5th to 6th; Rockingham, 6th
Possibly the most controversial move
came in Moore County, which is now in
two districts. The northern half of the
county was placed in the 6th District,
while the southern half remained in the

New DOT secretary; get
high marks from staff
By SCOTT PHILLIPS
DTH Staff Writer
After just one month in office, William
R. Robertson, the state's new secretary of
transportation, has received favorable
ratings from department personnel and
has begun to implement new programs.
Robertson's predecessor, Thomas Brad
shaw, resigned his position to pursue other
interests, department spokeswoman Doris
Gupton said recently.
Gupton said that Robertson had made
a favorable impression on DOT employees.
"Anyone who has had dealings with him
seems to like him a great deal," she said.
"(Gov. Jim) Hunt got the right man."
In announcing Robertson's appoint
ment July 9, Hunt said, "Of all the can
didates I looked at, Bill Robertson is the
person who, best fits the qualification I
outlined." The new secretary was sworn
into office July 25.
Robertson's major qualifications for
the position seem to be his success in build
ing and managing his businesses and his
legislative experience, Gupton said.
Robertson, a 63-year-old businessman
from Washington, N.C, owns three broad
cast facilities and several soft-drink bot
tling firms. He also served in the state
House of Representatives from 1967 to
1969 and from 1971 to 1973. But, he has
had no previous experience in the depart
ment. Hunt praised Robertson as a "hard
nosed, experienced and capable business
man who will know how to manage the
employees of the department, to fully uti
- lize the equipment owned by the depart
ment and to obtain the maximum benefit
from every dollar."
Hunt has stated several objectives for
the department under Robertson.' They
include, decentralizing decision-making
authority, restoring employee morale,
closer scrutinization of the department's
equipment and motor pool and working
more closely with the bid-rigging oversight
commission, Gupton said.
Robertson recently made his first
changes in department personnel by hir
ing two administrative assistants and by
announcing his plan to hire Floyd Bass as
an assistant secretary. He also announced
that 183 jobs would be lost within the year
and that 360 other jobs would be cut by
July 1983. .
