KU physicist aids NASA in Jupiter probe

A space physicist at the University of
Michigan is tasked with finding a puzzle,
but he must help find the puzzle.
The puzzle is the origin and works of our solar system, and the pieces may be found near the moons of Jupiter or the rings of Saturn.
The mission, called Mariner Jupiter-Saturn (MJS), will begin when the first probe lifts off from Cape Canalver Aug. 20. The second probe will follow 12 days later.
For the past five years, Thomas Armstrong, professor of physics and astronomy, has helped plan and design two unmanned spacecraft that will travel to the edge of the solar system.
"THE INFORMATION we generate will be part of the general body of knowledge on the solar system," Armstrong said, "and researchers and investigators for decades to come."
The two spacecraft, equipped with what have been called the best television cameras ever mounted on an interplanetary satellite, are orbiting the giant of the solar system, and its 14 mission.
It will take about two years for the probes to reach Jupiter and start sending back the first high resolution pictures of the planet. Other missions: Io, Europa, Ganymede and Callisto.
The probes will be whipped past Jupiter by its strong gravitational force and be on

their way to Saturn and its mysterious rings.
"I'd expect the Jupiter-Saturn craft to fairly well resolve the structure and composition of the rings," he said. "They could have icy mountains or ice-covered rock of some kind."

ARMSTRONG SAID the pictures and data from the probes should solve the problem.

Armstrong said he became involved with the Jupiter-Saturn mission in 1972 when NASA announced plans to send a spacecraft to the outer solar system.
He was a member of a team of scientists
who proposed to NASA that the probes include an instrument that could detect and measure radiation and charged atomic particles.
NASA AGREED, and members of the team developed Low Energy Charged Particle (LECP) systems, which now are installed and soon will be mounted on the probes.
Armstrong said that he helped set design goals for the LECP system, but that actual construction was done at the University of Notre Dame and Johns Hopkins University in Baltimore.
The MJS mission will reach Jupiter and I about five years after the primitive Pioneer 10 and 11 probe, which took photographs of Jupiter in 1873 and 1874. However, the MJS probes will be about 35 times better than Pioneer's, Armstrong said.
IT IS THOUGH that Jupiter and Io somehow are electrically conductive and act as giant electromagnets, he said. (He added that charged particles abbing from Io to Jupiter.)
Once the probes begin, Armstrong said, much of the data will be sent to him to be sorted and analyzed through KU's physics and chemistry computers. He said three graduate assistants would help in the data analysis.
Studying Jupiter's magnetic field may help scientists understand Earth's field, he said. The LECP system will be able to pick objects from the charged particles of Jupiter's field.
HE SAID that his main interests were in the magnetic field over Jupiter, which is larger and about 20 times stronger than Earth's. Earth's magnetic field makes compasses point toward Alaska rather than straight at the North Pole, he said.
"The problem relates to the source of the magnetic field," Armstrong said. "It is generated inside the Earth by mechanisms that are not understood."
The first MJS probe will pass through a "flux tube" of highly charged particle activity that stretches between Jupiter and its moon Io. Armstrong said.
The first probe will pass within 15,000 miles of Io, and its cameras will be able to photograph surfaces of a few hundred years in area.
AFTER TAKING more shots of Europe, cannyne and Callato, the mission heads to the Russian border.
Armstrong said the major focus of the mission after Jupiter was Saturn's largest moon.
Titan is about half the size of Earth, and some scientists think its atmosphere is almost as thick as Earth's. The first probe will pass within 2,600 miles of Titan, and Armstrong close pictures of Titan's surface reveal whether life could exist there.
RECENT DATA have led scientists to in-
vestigate the atmosphere consists of methane and hydrocarbons.
Jews Against Zionism
Armstrong said that when the sun's ultraviolet rays reacted with methane and hydrogen, it could produce several types of ice on the basis of all life as we know it.
... I became convinced . . . that Zionism was contrary to every principle I cherished as an American. I had experienced Zionism's distaste for free open debate. I had wifnessed its efforts to impose economic and social sanctions against any articulated public disagreement. I knew that the basis of its nationality claims was—when all was said and done—a religious criterion. I knew that its state had, from the beginning, lied about the Palestinians who were (non-Jewish people) nationals of Palestine. I knew that Zionism deceived American Jews and intimidated Americans.
(My anti-Zionism was now being fleshed out. . I gained my first clear and long lasting impressions and specific details about what Zionism was doing to human beings other than Jews.
It also is thought that ammonia may be present in Titan's atmosphere and ice-cooled surface. Armstrong said that in several lab studies amino acids were produced when electric currents were run through ammonia, and methane and water.
When such a national ideology became married to a religion, I told the senator Mark Hatfield, I feared for the integrity of the religion; and for many of the same reasons, I feared the corrosion of American democratic values if the U.S. continued its support of this anti-democratic nationality.)
Amino acids are the building blocks of complex proteins such as DNA and RNA,
Although the MJS mission isn't biological, Armstrong said, "Organic compounds could be stable in Titan's atmosphere. The minerals and amino acids are precursors to life."
In addition to studying Titan, the MJS probe will photograph six of Saturn's nine moons.

AS THE PROBES pass Saturn—the cameras exposing the composition of its rings—the LECP system will check for radiation and magnetic fields around it.
Armstrong said the probe might snow whether the rings were formed by a magnetic field that may have existed in Saturn's early years.
"The tests may not have anything to do with the present structure of the rings," he said. "But they may explain how they got there."
As for our immediate universe, Arm-
saw said, the pieces he chose to find
been taken.
"We have to understand all the details of the present solar system," he said, "and then try to infer from what we find how it got that way."
