UAHuntsville students aspire to be next generation of rocket scientists
When I grow up, I want to be a rocket scientist.
Some kids dream of one day becoming a doctor, veterinarian or perhaps a lawyer. But each dream is fueled by different things. There is an aspiring group of students and professors at The University of Alabama in Huntsville whose childhood aspirations were to become rocket scientists. Now, they no longer have to imagine the possibilities — rocket science is their reality. They are contributing vital research to NASA's Constellation Program, which is working to build America's next spacecraft to return humans to the moon.
The students and professors are participants in the Constellation University Institutes Project (CUIP). The project comprises 24 universities in association with the Constellation Program. The teams work to address some of the technical issues of space access and exploration, including rocket stability and high performance, inexpensive solid propellants. Such issues are critical to the development of Constellation's spacecraft, and these aspiring rocket scientists rise to the challenge.
Dr. Robert Frederick, professor and director of the Propulsion Research Center at UAHuntsville, leads two of the university's three CUIP teams. With his current role, Frederick is able to build upon his own aspirations for the next generation.
"When I was a child, people were going to the moon," he said. "Now, I can help other young people achieve their childhood dreams of working on rockets and being in the propulsion industry."
Frederick's teams are focusing on thrust chamber assembly and solid propellant research. Their tasks include evaluating and improving a laboratory-scale injector test facility and developing solid propellant characterization techniques. This is fundamental science for aspiring rocket scientists.
Ashley Penton, a master's candidate in mechanical and aerospace engineering, works on one of Frederick's teams. In addition to realizing her dream of becoming a true rocket scientist, Penton is excited about the real-world application of her work.
"We are looking at burn rates for solid propellants," Penton said. "This work is helping NASA because they are looking at using solid propellants for future rockets."
These rockets include the J-2X rocket engine, an upgraded version of the J-2 rocket that helped power the Saturn V vehicles that carried Apollo astronauts to the moon. The J-2X is part of the Ares I rocket that will launch the Orion crew exploration vehicle to the International Space Station by 2015 and on to the moon by 2020. The team's work is directly related to developing this new rocket engine system.
For teammate Tony Marshall, his childhood dream of working for NASA started in elementary school.
"My class took a field trip to the Marshall Space Flight Center and to Space Camp and I said to a friend of mine that I wanted to do that some day," Marshall said.
Marshall's work on the CUIP program has paid off and his dream is now a reality.
"Since I have been on the team I have accepted a job that is located at the Marshall Space Flight Center," he said.
As the space shuttle program nears retirement in 2010, the Constellation Program will advance future space exploration, and UAHuntsville students are getting to work first-hand on America's space program. Along this journey, aspiring students such as these may become NASA's next generation of rocket scientists.

UAHuntsville student embraces dream of becoming an aerospace engineer
Five years ago, University of Alabama in Huntsville (UAHuntsville) student Paul Burns, the owner and installer of a small, South Carolina burglar and fire alarms company, had a vivid, mental image of himself in his 50's or 60's still crawling under houses running wires to make a living.
It was not appealing.
Burns decided then that he would make his childhood dream of being an aerospace engineer a reality — even if he had to close his company to make it happen.
"I worked as owner/lead installer with approximately 30 employees (mostly salespeople) and was making around $65,000 per year, which was a decent income for someone uneducated, but I wanted more in life than just money."
Burns first memory of space travel was the liftoff of the Spacelab mission. And, although he was a young boy and his memories of the Spacelab era are fuzzy, it made a lasting impression. "For the rest of my childhood I wanted to be an aerospace engineer, even though I didn't know what it really meant. I just knew that it had the word ‘space' in it. My thoughts wandered to this era of my life that Christmas of 2003. I thought to myself that if I wanted to live that childhood dream, I'd better do it now."
Just after the New Year in 2004, Burns told his employees that he was closing the business and going back to school. He stayed on in Charleston for four months taking an extended vacation. Burns also worked as a stand-in actor, for Kevin Connolly, during the filming of the Hollywood movie, The Notebook.
"I was getting bored and saw a casting call for extras, and since I had been an extra in the movie "The Patriot" starring Mel Gibson, I decided to give it a shot. I was surprised when I received a phone call from the casting director asking me if I wanted to be a stand in for Kevin," he said.
Burns moved to Birmingham and attended Jefferson State Community College. Eventually, he moved to Huntsville to continue his education at UAHuntsville.
As a college student Burns quickly proved to himself that he could excel if he really wanted to. His high school algebra teacher, Barbara Neal, recognized a diamond in the rough years ago when she told Burns of his latent ability.
By his own admission, Burns had a less than stellar high school experience. "I did not like school and barely graduated … I was the antithesis of the Valedictorian," he admitted.
Clearly not interested in continuing his education after high school, Burns enlisted in the Navy at 17 (his parents granted permission). "I spent just over four years in the Navy operating and maintaining the Mark 92 Gun/Missile Fire Control System on the USS Halyburton, FFG-40, during which time I participated in Operation Desert Storm."
In 2007 Burns applied for the UAHuntsville's Cooperative Education program and was hired at Arnold Air Force Base (AFB) in Tullahoma, Tenn.
"During my two back-to-back semesters there, I worked on intake analysis on the T-38C/PMP and the new Joint Strike Fighter, the F-35 Lightning II," Burns said. "My mentor, Dr. Donald J. Malloy (with the Aerospace Testing Alliance at Arnold), had the confidence in my ability to support flight test activities on-site at Edwards AFB in Lancaster, Calif., in support of the T-38 and the F-35.
"Our first trip to Edwards was for one week, in which we attended meeting after meeting concerning these two aircraft. I quickly decided that, because I would only be a co-op employee for a short time, I would focus the remainder of my time developing analysis techniques for the T-38C/PMP program," he explained.
Burns, along with several others from Arnold and Edwards AFB, developed methods to combine ground test and flight test data to anticipate engine compressor stall characteristics for the T-38. From November 2007 to May 2008, he traveled to Edwards AFB a total of four times. For this effort, Capt Charles M. McNiel and Dr. John L. Jordan of Arnold AFB, and David Kidman of Edwards AFB nominated Burns, as well as the rest of the team, for the Tennessee chapter AIAA Billy J. Griffith Engineering Analysis Award. Burns accepted the award at a banquet last October.
While at UAHuntsville, Burns received scholarship money as a Charger Chaser and worked as an assistant in the Engineering Student Affairs Office.
He will graduate from UAHuntsville this spring. "I sincerely hope I will be able to move back to Arnold AFB to continue my career, obtaining my childhood dream of becoming an aerospace engineer.
Burns' future plans include attending the University of Tennessee Space Institute for graduate school. "One day I hope to add those three important letters to the end of my name, Ph. D."
New supercomputer will help explore the universe
Scientists in UAHuntsville's Center for Space Plasma and Aeronomic Research (CSPAR) will soon be using one of the fastest supercomputers in the state to help them explore the universe.
Able to run almost 4.2 trillion computations per second (4.2 teraflops), a new Dell supercomputer being installed in Cramer Hall has ten times the computing power of the computer it replaces and might be the third fastest state-owned computer in Alabama.
It will cut the processing time needed to run CSPAR's mathematical models of the sun's bubble in the galaxy from two or three weeks down to two or three days, according to Dr. Vladimir Florinski, an assistant professor in physics.
(Four trillion calculations per second, times 72 hours equals ... about one quintillion calculations per model run.)
One of the new computer's tasks will be to analyze data gathered by NASA's new Interstellar Boundary Explorer (IBEX) satellite and from the two Voyager deep space probes. All three are collecting information on the size and shape of the heliosphere, the sun's bubble in interstellar space.
CSPAR scientists are studying the turbulent boundary region where the solar wind slams like a snow plow through space into the thin soup of particles, plasma and magnetic fields swirling around the Milky Way in the space between the stars.
The new computer was purchased through the Pei-Ling Chan eminent scholar endowment. The computer it replaces will be used as a teaching tool so graduate and post-graduate students can learn the skills needed to prepare models and data for distributed processing on a super computer.
"That isn't a trivial task and there is no software to do the process for you, so it is an important skill to master," said CSPAR Director Gary Zank.
UAHuntsville graduate named CEO of NASA's Michoud Assembly Facility
Clyde S. "Chip" Jones, a native of Huntsville, and a 1978 electrical engineering graduate of The University of Alabama in Huntsville, has been appointed chief operating officer for Michoud Assembly Facility in New Orleans. The appointment was made by David King, director of NASA's Marshall Space Flight Center in Huntsville Ala., which manages the Michoud facility.
Jones will be responsible for day-to-day management and operation of the 830-acre Michoud facility, which employs more than 4,000 workers.
Michoud is responsible for the design, manufacture and assembly of the space shuttle's external tank. Michoud also has been selected to support NASA's Constellation Program for the agency's exploration missions to return to the moon and travel beyond. Work there has already begun for the Orion crew exploration vehicle, while planning is underway for the Ares launch vehicles, all part of the Constellation Program.
"Mr. Jones will be responsible for ensuring that NASA is well-positioned to support large-scaled manufacturing necessary for all current and future launch systems," King said. "Varied technical expertise and solid business acumen, combined with his thorough knowledge of NASA's mission to return to the moon, make him the ideal person to serve in this position."
Jones previously served as manufacturing and assembly manager for the Ares I Upper Stage, and was responsible for delivery of all development, test and flight hardware for NASA's newest launch vehicle, which will send crew members on board the Orion crew launch vehicle into space.
From 2004 to 2005, he was external tank resident manager at Michoud Assembly Facility, overseeing the shuttle's external tank manufacturing activities.
Jones served from 2002 to 2004 as group lead for Metallic Materials and Processes in the Materials & Processes Laboratory in Marshall's Engineering Directorate and was responsible for metals development, testing and welding. In 1992, he was named team lead for welding in the Materials and Processes Laboratory. He led the use of robotic welding for the International Space Station structures, and led development of friction stir welding for the external tank. Jones began his NASA career in 1981 as an electrical engineer in the Science and Engineering Directorate, working on robotic and computer controlled welding systems.
Jones received his UAHuntsville degree in electrical engineering in 1978 and has completed graduate studies in control systems.
He has received numerous awards and honors, including a Director's Commendation in 2006 for his response to Hurricane Katrina and a U.S. patent award in 1998 for a method for marking, capturing and decoding machine-readable matrix symbols using magneto-optic imaging techniques.
Also in 1998, he was honored with the NASA Medal for Exceptional Achievement for leadership of the welding team.
Mr. Jones and his wife Laura reside in Fayetteville, Tenn.
UAHuntsville joins NSA, DoD systems engineering center
The University of Alabama in Huntsville joins 17 other universities and research organizations across the U.S. today in launching the new National Security Agency and Department of Defense-supported Systems Engineering Research Center (SERC).
Based at Stevens Institute of Technology in Hoboken, NJ, the center was created to improve the systems used to develop, test, integrate and sustain complex defense and security services and systems, including weapons systems.
"UAH has been involved in systems engineering research for the Army for several years," said Sue O'Brien, acting director of UAHuntsville's Rotorcraft Systems Engineering and Simulation Center (RSESC). "We are excited about working with the other collaborating universities, sharing our expertise, learning from their strengths and then bringing what we learn about the best practices in systems engineering back to the Huntsville community."
Research engineers and scientists at RSESC and UAHuntsville's Industrial and Systems Engineering Department are involved in both of the new center's first two projects: Assessing the effectiveness of systems engineering in major defense acquisition projects, and evaluating the systems engineering methods, processes and tools used in both defense and intelligence community programs.
One of the tools that will be assessed is the Systems Engineering Toolkit, a computer program created at RSESC for Army aviation, missile and space programs based on guidance from the secretary of defense.
The decision to create a University-Affiliated Research Center was influenced by growing challenges in producing increasingly complex systems using rapidly evolving technology while serving multiple clients, such as two or more branches of the military.
A 2008 U.S. General Accounting Office survey of eleven weapon programs with quality control problems related to systems engineering, manufacturing or supplier quality found cost overruns up to $846 million with schedule delays from several months to five years.
Stevens Institute of Technology is the center's lead institution, with the University Southern California as principal collaborator. Other collaborating institutions are UAHuntsville, Auburn University, the Air Force Institute of Technology, Carnegie Mellon University, the Fraunhofer Center at the University of Maryland, MIT, Missouri University of Science and Technology, Penn State, Southern Methodist, Texas A&M, Texas Tech, the University of California at San Diego, the University of Maryland, the University of Massachusetts at Amherst, the University of Virginia and Wayne State University.

UAHuntsville Engineering’s Tony Luchner wants a part of robotics cutting edge for helping others
"It would be a way to give back to them," Tony Luchner said. "Robotics is on the new founding edge of technology and a field ready to be explored. I just want to give it what I can."
Luchner, 26, of Huntsville, a computer engineering senior at The University of Alabama in Huntsville (UAHuntsville), has a specific application in mind when it comes to research and development in robotics — prosthetics, or artificial human limbs.
Before arriving at UAHuntsville in the fall of 2005, Luchner served five years in the United States Marine Corps, which included two tours in Iraq. He got the idea for his career goal from a desire to help soldiers who have lost limbs in military service.
Luchner had a keen interest in robotics while a student at Grissom High School, and continued that interest into the Marine Corps. He received early electronics training by the military and served in Iraq as an electronics specialist for the Huey and Cobra helicopters.
Since military service, Luchner has been heavily involved in robotics through the UAHuntsville chapter of the Institute of Electrical and Electronics Engineers (IEEE). He has helped in the design and/or production of numerous robotics systems; battery operated and guided by infrared, sonar, or camera systems. He says his career challenge will be developing systems that work with the human brain.
Also helping Luchner prepare for future research and development is his current internship with ITT. This fall, he’ll continue to work part time at ITT and help get the IEEE team ready for SoutheastCon hardware competition. Next year’s competition will involve a litter robotics system, designed to pick up cans, plastic bottles and glass bottles.
After graduation in May 2009, Luchner plans to begin work on his master’s degree through research and development, and then work for one of the nation’s companies that manufacture prosthetics.
Jennifer English's Journey
UAHuntsville engineering professor
embarks on an emotion-filled trip after
she learns of her cancer diagnosis
It was just a year ago that Jennifer English learned that fate would provide her with a crushing blow — invasive ductal carcinoma. Breast cancer.
During the past 12 months, she has undergone a left mastectomy. Jennifer and her family have undergone six months of chemotherapy and six weeks of radiation treatments.
Today, the reports are much more positive. She is in remission. She is walking and running four miles a day. She is preparing to travel to Atlanta later this year to walk 60 miles to benefit the Susan G. Komen for the Cure and National Philanthropic Trust, funding important breast cancer research, education, screening, and treatment. The event is scheduled October 24-26.
Jennifer is using this event as part of her mental and physical recovery. But, she is motivated for other reasons.
"I am walking for those who have lost the battle with this disease. I am walking so that my daughter does not have to face this disease," she said.
She has been overwhelmed by the response for donations to her efforts. She established a fund-raising goal of $2,200 and reached that goal rather quickly. Another goal of $4,500 followed. She also reached that goal on July 29.
Jennifer is an associate professor of electrical and computer engineering The University of Alabama in Huntsville. She is a tenured professor. Married to Bill for 14 years. Mother of two children: Jeffrey, 9. Mary, 6.
Since Jennifer’s world was shattered last July, she has embarked on an emotion-filled trip through the world that is too frequently traveled by too many women.

UAHuntsville Space Hardware Club
second nationally in CanSat contest
The Space Hardware Club at The University of Alabama in Huntsville captured second place honors nationally with its construction of CanSat, a "satellite" that has the dimensions of a soft-drink can.
The CanSat contest was a competition where no more than 10 students from any accredited university would build a device no bigger than 72 millimeters in diameter and 279 millimeters in length, the approximate size of a 12-ounce soft drink can.
The CanSat was rocketed to approximately 2,000 feet where it was ejected and deployed a parachute. Students had to build the machine to perform several tasks autonomously. The CanSat measured and recorded on-board data on temperature, pressure, velocity and altitude and transmitted that information to a ground station. Upon its landing, CanSat had to right itself on the ground and measure the surface temperature of the soil.
UAHuntsville finished second among 20 teams at the national competition in Amarillo, Texas, besting Virginia Tech, the University of Michigan and Washington University in St. Louis, each of which sponsored two teams. Other top teams listed for the competition included Penn State, Tuskegee University, Michigan Tech, Texas A&M, and the University of Texas-Arlington.
Finishing behind New Hampshire and UAHuntsville were the University of Michigan (third and fourth) and Virginia Tech (fifth).
Georgia Richardson, an assistant professor of mechanical engineering and the group’s faculty sponsor, said the students get no course credit for this exercise, but get experience that will help them in their coursework. "They developed multi-disciplinary skills with this project. They had electronic systems, a power system, a mechanical system and had to work together as a team to ensure all the pieces fit together in the end."
UAHuntsville students said the requirements for the contest were challenging beyond just building the small instrument. The technical requirements included a descent rate of no faster than 4.6 meters per second, and total descent time could not exceed seven minutes. The altitude had to be transmitted to the ground station every five seconds and if a parachute is used as a main recovery device, it must have been released within one meter of the ground. Also, CanSat could cost no more than $1,000 to build.
Dr. Richardson said the two most difficult goals were being able to communicate with the instrument through the entire flight and autonomously up-righting the instrument after landing. "The student’s vehicle performed both of these tasks flawlessly."
Seiya Shumizu, a mechanical and aerospace engineering major from Tokyo, was project manager, and wrote most of the code for the flight-control software. He concentrated his time on software design as well as time and risk management.
"This was my first experience to lead a team project, so I was very anxious when the project started," he said. "The success gave me confidence, but it also taught me what I should improve. For example, I underestimated the importance of time management. I sometimes failed to redirect the team when necessary. Next time, I can do better."
Paul Watts, a mechanical and aerospace engineering major from New Jersey, served as mechanical team leader. "I had to ensure that all of the mechanical aspects of the CanSat were reliable, strong, lightweight and low cost."
Watts aspires to become a vehicle designer. "Anything from high-performance jets to electric cars and anything between," he said. "I want to design because it allows me to be creative while also requiring me to use what I have learned at UAH which is, so far, all stuff that I enjoy."
Eric Becnel, a mechanical engineering major from Mandeville, La., led the design and construction of the landing system. "I was chosen for this responsibility because I have most of the machining experience on the team from working with other clubs."
One of the key lessons Becnel said he learned from this project was the importance of testing. "This project showed me how important testing is on a system. As I started building different mechanical models, parts would break. We would sit down and figure out why that was a weak point and develop from there. Seeing how testing help find problems before launch day, it really is valuable."
Fuhito Fukazawa, a mechanical engineering student from Tokyo, agreed that testing and teamwork are critical for such ventures. "Communication is vital in all of the projects and I also learned that testing is very important. If any of three components — mechanical, electrical, and communication — fails, the CanSat cannot fly."
James Mulroy, a mechanical engineering student from Hortonville, Wisc., was the group’s Alternate Project Manager. He assisted the team lead, but also kept track of the project’s costs and assisted the electrical team.
Mulroy jokes that the experience will look good on a resume, but he also learned real world work experience. "When going to college and taking classes you only learn what they teach you in class. They don't tell you what's really going to happen on the launch range...because they can't; it's too complex. It's something you can only learn by experiencing it. This project gave me that — experience."
Richardson said the CanSat is the next step for the students to construct a larger satellite — the CubeSat. "They have done several BalloonSat instruments (weather balloons) as the first step, " she said. "Balloon payload can be relatively large and heavy (~12 pounds) compared to a CubeSat (~2.2 pounds), so this CanSat step helps them learn how to do things in small packages. The BalloonSat step helps them learn how to build things that will survive in space. The balloons go up to 100,000 feet where the environment is very similar to the on-orbit environment of a CubeSat."
The CanSat competition is sponsored nationally by the AIAA, AAS, Naval Research Lab and NASA. The Space Hardware Club was supported by the Alabama Space Grant Consortium, the UAHuntsville Student Government Association, and the university’s Mechanical and Aerospace Engineering Department and Center for Space Plasma and Aeronomic Research.
