Comet dust studied at Advanced Photon Source
By Donna Jones Pelkie
They came from outer space.
And now, particles of comet dust that traveled from the far reaches of the solar system to Earth are traveling the United States , including a stop at Argonne 's Advanced Photon Source (APS). Scientists there are studying the particles to learn more about comets and possibly the creation of our planet.
The particles are the first pieces of a comet to have ever been plucked from outer space and returned to Earth. The collection was part of NASA's Stardust sample return mission which launched in February 1999. The primary goal of Stardust was to collect dust and carbon-based samples during its closest encounter with Comet Wild 2. The Stardust sample-return canister parachuted onto the desert salt flats of Utah on Jan. 15, following a journey of nearly three million miles and bringing with it thousands of particles from the edge of the solar system.
Four of those samples recently spent a few days at Argonne , and almost that entire time they were bombarded by the high precision X-ray beams from APS. The samples are so small that several particles fit across the width of a single human hair. By using the APS to map the samples, researchers hope to determine their chemical makeup and to gain a better understanding of the composition of comets and other planetary bodies, including the Earth. The studies were done at GeoSoilEnviroCARS, a research facility at the APS operated by the University of Chicago .
Comets form far out in the solar system, explained researcher George Flynn of SUNY Plattsburgh who is working on the project with Steve Sutton and Matt Newville of the University of Chicago . They have trapped original parts of the solar system in ice for four and a half billion years. We have material that we think is the original dust that the solar system formed from. And if we want to understand the Earth, we need to understand what it's made of.
The particles were captured in aerogel, a special type of foamed glass, made so lightweight that it is barely visible and almost floats in air. Looking at the aerogel microscopically, Flynn said, it would resemble a spider web. The particles travel through it, hitting individual strands of the web, slowing with each impact, and eventually becoming embedded in the gel. The comet particles make carrot-shaped tunnels in the aerogel as they are stopped. At the pointed tip of each tunnel, a tiny particle will be found.
Researchers are analyzing the particles while they are still embedded in the aerogel. They use the APS to map the elements along the track left by the comet particles. The aerogel is abrasive, and as the particles travel through it, parts of them are scraped off and embedded in the track.
If we just remove the particle and analyze only that, Flynn said, it might not be a true representation of the particle composition. Researchers will map the elements along the path as well as the particle, and then we'll add them up and see what we get, Flynn said.
Flynn and his colleagues will also compare the data collected from these comet particles to data on particle samples that NASA routinely collects from the Earth's upper atmosphere. Researchers have long believed that some of those particles are, indeed, from comets, but without confirmed comet samples to compare to, there's been no way to know for sure. This project finally gives scientists the opportunity to determine the unique characteristics of a comet. Flynn says researchers hope that if a comet is sufficiently uniform, then by collecting such tiny pieces of it we can understand a lot.
Prior to landing at Argonne , the samples were analyzed at the Advanced Light Source at Lawrence Berkeley National Laboratory and the National Synchrotron Light Source at Brookhaven National Laboratory. Using the APS, the samples can be studied at much higher energies allowing researchers to detect heavier elements and map the samples at smaller scales.
After the samples leave Argonne, Flynn said, they will be returned to the Johnson Space Center in Houston where the particles will be extracted from the aerogel. Scientists there have the capability to extract particles down to about four microns in size. Researchers will slice the particles in half and analyze them. Some of the particles will then make a return trip to the APS where researchers will examine individual minerals in the particles at the submicron scale.
Once all research is finished, the samples will be housed at the Johnson Space Center and remain available for researchers around the world to study. Sutton pointed out that's why non-destructive studies such as this one are so valuable because the samples can be studied again in the future when even more refined methods become available.
Stardust is the first U.S. mission designed to return rock samples since the Apollo missions to the moon. Nobody would have imagined back when Apollo returned with the first space samples the types of studies that would be possible today, Flynn said. During the early years of space exploration samples needed to be much larger, and measurements could not be done with the sensitivity that is available today.
The real benefit of sample return, Flynn points out, is that the instruments used to study the material could not be taken into space. We could never send a synchrotron to the comet, he laughed.
Flynn and Sutton, who have been studying space particle samples together for nearly two decades, will present preliminary findings at NASA's lunar and planetary science conference this month. They hope to have their studies complete in six months.

Sattelberger named Associate Lab Director for Physical, Biological and Computing Sciences
Alfred P. Sattelberger has been named Associate Laboratory Director for Argonne 's Physical, Biological and Computing Sciences divisions. His appointment was effective March 1.
In this position, Sattelberger will oversee the mission and operation of Argonne scientific divisions that conduct research in nanoscale materials, materials science, bioscience, physics, chemistry, mathematics and computer science, and conduct the laboratory's educational programs.
Sattelberger is a senior laboratory fellow at Los Alamos National Laboratory (LANL) and a visiting research professor in the radiochemistry program at the Harry Reid Center , University of Nevada-Las Vegas . Prior to these assignments, he held several scientific and technical management positions at Los Alamos . From 1999-2004, he was director of LANL's Chemistry Division, an organization that grew to seven technical groups, a staff of roughly 450, and a budget in excess of $100M.
From 1994 to 1999, he was first deputy and then director of LANL's Science and Technology Base Programs Office, an office with primary responsibility for LANL's laboratory-directed research and development, externally funded science education programs, university outreach, technical assessment of the laboratory's science and engineering activities, and the postdoctoral program. From 1997-1999, he also served as the program director for Energy Research (now DOE's Office of Science) programs.
Earlier in his LANL career, Sattelberger served three years as the deputy division leader of the former Isotope and Nuclear Chemistry Division. Prior to that, he spent six years in the Inorganic and Structural Chemistry Group (INC-4). There he was a section leader for inorganic chemistry and principal investigator on several research projects dealing with actinide coordination and organometallic chemistry, organometallic chemical vapor deposition, and technetium-99 chemistry.

Link , Galicia receive QASR Award
Security Lt. Steven Link and Officer Edgar Galicia have received Quality and Safety Recognition (QASR) Awards for fast response and quick thinking in rendering first aid and assistance to an injured fellow officer.
The awards were presented during a recent management council meeting. Link and Galicia each received a certificate of recognition and lunch tickets for two at their choice of the Argonne Guest House or the Building 213 Cafeteria. Their names will also be added to the QASR Award Winners' plaque.
On Oct. 30, 2005, the Central Alarm Station at the Argonne firehouse received a call for immediate assistance from a Protective Force officer. While conducting a security patrol in Building 316, the officer tripped and fell into a door window, severely lacerating his left arm.
Link and Galicia were first to arrive at the scene, where they found the officer standing in a pool of blood, with shards of glass everywhere. Noticing the injured officer's slurred speech and disorientation, Link had him sit against a wall. He raised the officer's injured arm above the level of his heart and removed his own shirt to use as a compress to slow the bleeding. With assistance from Galicia , the bleeding was controlled until the Argonne Fire Department arrived. After basic treatment, the officer was taken to Good Samaritan Hospital in Downers Grove . He was treated and has fully recovered.
The QASR Award recognizes employees' contributions to safety and quality at the laboratory. Safety is vital to the laboratory's ability to conduct research and development on behalf of the nation, and that safety depends on the efforts of conscientious employees who find, report and fix potential hazards and who look out for the safety and well being of their colleagues.
Nominations for the QASR award can be sent to Audra Karalius (EQO) at karalius@anl.gov.
Foster to lead Computation Institute
Ian Foster (MCS) has been appointed director of the Computation Institute, a joint project between the University of Chicago and Argonne that addresses the most challenging computational and communications problems arising from a broad range of intellectual pursuits.
Foster succeeds Rick Stevens, director of the Mathematics and Computing Sciences Division at Argonne and professor in Computer Science at the university.
Also appointed, as associate director of the institute, is Jonathan Silverstein, assistant professor in Surgery at the university.
Ian Foster and Jonathan Silverstein are the perfect team to bring together university and Argonne scientists from across the disciplines to lead the Computation Institute to the fore in this grand challenge, said Thomas Rosenbaum, the University of Chicago's Vice President for Research and for Argonne National Laboratory.
A pioneer in grid computing, Foster is associate director of Argonne's Mathematics and Computer Science Division and the Arthur Holly Compton Distinguished Service Professor in Computer Science at the University of Chicago . The high-speed networking of grid computing provides access to both raw computer power and special data or instrument resources on demand, much the way an electric power grid provides electricity.
Computation plays an increasingly central role in many disciplines in the sciences, medicine and the humanities, Foster said. What we want to be about is not just doing bigger computations, but working out how to apply these computation tools in new ways and to new disciplines.
The Grid movement is largely supported by the Globus Project, which Foster co-founded in 1995 with Steve Tuecke, formerly of Argonne but now chief executive officer of Univa Corporation, and Carl Kesselman of the University of Southern California . Since then they have initiated a variety of commercial and academic enterprises based on their software package for building Grid systems and applications, the Globus Toolkit.
Globus underpins numerous projects, including TeraGrid, a national system of interconnected computers that scientists and engineers will use to solve some of their most challenging problems. TeraGrid, which is overseen by the Computation Institute, could potentially affect every major scientific discipline that requires intensive computing capabilities.
Foster, Kesselman and Tuecke founded Univa Corporation, based in Elmhurst , Ill. , to promote the commercial use of Globus technology. Foster also co-led the launch of the Grid Physics Network (GriPhyN), in 2000.
More than 120 researchers at Argonne and the university belong to the Computation Institute. Founded in 1999, the institute encompasses research in the biological, physical, social and financial sciences, medicine, law, the arts and the humanities.

DOE requests 14 percent increase in budget
The U.S. Department of Energy's fiscal year 2007 budget requests $4.1 billion for the Office of Science, a $505 million (14.1 percent) increase over FY 2006 funding. This budget puts DOE's Office of Science on the path to doubling its budget by FY 2016.
The budget request for Basic Energy Sciences was $1.42 billion, a $286.4 million increase over FY 2006. A large portion of this request enables the Office of Science to continue design and construction of the Linac Coherent Light Source ($105.9 million total).
Funding increases will also support nanoscale science research (up $51 million); the Hydrogen Fuel Initiative (up $17.5 million); the first full year of operations of the Spallation Neutron Source at the Oak Ridge National Laboratory (up $99.7 million); and provides research and development and project engineering design for the National Synchrotron Light Source II project (an additional $45 million).
Other programs were also targeted for increases:
Biological and Environmental Research: $510.3 million, a $54.6 million increase over 2006.
High Energy Physics Program: $775.1 million, a $58.4 million increase over FY 2006.
Nuclear Physics Program: $454.1 million, an $87 million increase over FY 2006. The funding increase would restore operations at both the Thomas Jefferson National Accelerator Facility and the Relativistic Heavy Ion Collider.
Advanced Scientific Computing Research Program: $318.7 million, an $84.0 million increase over FY 2006.
Details are online at the DOE Web site.
AST-NS reorganizes
Argonne management has reorganized Applied Science and Technology-National Security (AST-NS), under the direction of Associate Laboratory Director Alan Foley. The reorganization eliminates the Energy Technology Division and merges its functions into the remaining AST-NS divisions.
Division directors in AST-NS, the associate laboratory director's office and Human Resources have already started to work with Energy Technology to make this transition as smooth as possible.
Generally, entire sections will be transferred to other divisions -- probably to Nuclear Engineering, Energy Systems, Chemical Engineering and possibly Environmental Science. Not all functions fall neatly into existing organizations, and some adjustments will be made on an individual basis.
A voluntary Reduction in Force (RIF) has been offered.
Administratively, everyone will report to the new divisions as of Saturday, April 1. Responsibilities for experimental work will be transferred to the new divisions. This includes control of lab space, ownership of equipment and special materials, experimental safety review, Job Hazard Questionnaires, and Environment, Safety and Health training records. A number of documents will have to be revised, and in some cases approved, in order to reflect the new organizational structure.

Branding guide available online
A new document, Brand Identity Guidelines, which summarizes key aspects of the new Argonne brand and how it impacts Argonne communications, is now available online.
Argonne's new logo is the visual symbol of the new Argonne brand, announced by Laboratory Director Robert Rosner in his State of the Laboratory address Feb. 28.
Topics in “Brand Identity Guidelines” include brand positioning and personality, proper use of Argonne's name and logo, color palette, typography and examples of printed materials that properly reflect the Argonne brand.
Communications and Public Affairs and the Technical Services Division are working on new templates for business cards, letterhead, memos, PowerPoint and other documents. They will be announced as they become ready over the next few days.

Delta symbolizes change, diversity
The delta symbol, which makes up the colorful part of the new Argonne logo, symbolizes change. The colors on the three sides represent Argonne 's diversity, as reflected in the many talents, cultures and scientific disciplines of the laboratory's staff, as well as the variety of experimental facilities on site. The blended colors at the corners represent the way the multidisciplinary talents attracted to the laboratory combine to produce new ideas, discoveries and inventions.
