7 CU engineering students among the Big Brains
Nov 13th
among 20 national engineering leaders
Seven University of Colorado Boulder aerospace engineering students are among 20 top students who will be recognized Nov. 14 with a new national award honoring tomorrow’s engineering leaders sponsored by Penton’s Aviation Week in partnership with Raytheon.
The “Twenty20s” awards honor the academic achievements and leadership of top engineering, math, science and technology students.
The CU-Boulder award winners are doctoral candidates Paul Anderson, Brad Cheetham, Jake Gamsky, Erin Griggs and Dan Lubey, and B.S./M.S. students Kirstyn Johnson and Mike Lotto. The awards will be presented during Aviation Week’s annual Aerospace & Defense Programs Conference in Phoenix.
“I am delighted with the national recognition our outstanding aerospace undergraduate and graduate students are receiving from Aviation Week,” said Penina Axelrad, chair of CU-Boulder’s Department of Aerospace Engineering Sciences. “All of them bring incredible passion and impressive technical skills to their classwork and to an extensive portfolio of professional and extracurricular activities. Each is on a fast track to making remarkable contributions in fields like space exploration and satellite-based Earth observations.”
The high-profile projects and research portfolios of the seven students cover a wide range of critical issues facing the field of aerospace engineering today.
Working closely with the Federal Aviation Administration, Cheetham has been developing and co-teaching graduate-level courses on commercial spaceflight, while Gamsky is helping to design the Dream Chaser commercial spacecraft as an intern at Sierra Nevada Corp. and conducting research on human spaceflight life-support technology.
Griggs is developing a next-generation Global Positioning System receiver for spacecraft. Anderson is working to model geostationary space debris and Lubey is studying space situational awareness to detect and model satellite maneuvers.
In their senior year of the undergraduate portion of their concurrent B.S./M.S. degrees, Lotto and Johnson both hold perfect 4.0 grade-point averages and have completed internship or co-op experiences with NASA. They are working together as part of a capstone senior project design team that is developing a dust impact monitor capable of measuring the size of tiny cosmic dust particles near the surface of the sun.
In addition to their outstanding academic achievements, the students were selected for their leadership and civic involvement outside of the classroom. All are active in professional and student societies and volunteer their time to help others. From encouraging K-12 outreach to volunteering with Habitat for Humanity to mentoring and tutoring fellow classmates, the seven students all make service a priority.
“For most of us this is more than a career, it’s a passion,” said Cheetham, who three years ago launched the “We Want Our Future” educational initiative to inspire American youth and strengthen their interest in math and science.
Anderson, who mentors undergraduates and participates in outreach to younger students, agreed. “We’re fostering the next generation of engineers here,” he said. “We want to inspire them to continue the great things we’re doing in aerospace.”
Six of the seven students will attend the awards ceremony in Phoenix along with former NASA astronaut and aerospace engineering sciences faculty member Joe Tanner.
Tanner and Axelrad said the Twenty20s winners are representative of the high caliber of many of the students in CU-Boulder’s aerospace program, which is considered one of the best in the nation.
“Our department is proud to count these seven among our students and we look forward to watching their careers take flight,” says Axelrad. “We will continue to create opportunities for students like these to learn from our exceptional faculty, collaborate in hands-on projects with talented peers and industry partners, and engage in cutting-edge aerospace research.”

CU: more computers for more kids
Nov 7th
Computers To Youth program
The University of Colorado Boulder Environmental Center is expanding its Computers To Youth program to include more students and more interactive activities.
Computers To Youth provides high school students from underrepresented communities with upgraded used computers and hands-on training from CU-Boulder student mentors. Its purpose is to benefit underserved youth in Colorado and protect the environment. The computer systems received by the high school students through the program are designed to enable academic achievement that will encourage students to attend college.
“Not only do the high school students but also the college student mentors see this as an inspiring learning experience,” said CU-Boulder engineering student and Computers To Youth mentor Rebecca Miller. “The fact that CU-Boulder put together this program that saves resources, prevents waste and enables future scientists and engineers is completely brilliant.”
The next Computers To Youth event will be held Saturday, Nov. 9. Fourteen high school students from the Family Learning Center in Boulder, guided by CU-Boulder student mentors, will go through surplus computer components, bundle parts, load the latest software and take their newly built computer systems with them. The day also will include a new competition in which teams will race to disassemble and reassemble a demonstration computer.
“As technology increasingly becomes a part of daily life, those without computer access risk falling behind,” said Jack DeBell, the CU Environmental Center’s recycling program development director. “This consequence, known as the digital divide, tends to affect economically disadvantaged populations, especially youth. With such a great amount of computer equipment being discarded by a technologically advanced campus, it only makes sense that some of this equipment be “upcycled” to bridge the digital divide.”
The CU-Boulder student mentors are part of the statewide MESA (Mathematics Engineering Science Achievement) program. CU-Boulder’s MESA Center is headquartered in the Department of Pre-College Outreach Services in the Office of Diversity, Equity and Community Engagement (ODECE).
MESA Colorado also refers high school students to the Computers To Youth program.
With two additional Computers To Youth events slated for the spring semester, about 55 youth will be served by the program this academic year. The Denver Area Telecommunications Educational Telecommunication Consortium (DAETC) has enabled the increase in the number of participants, up from 48 last year, according to DeBell.
The CU Environmental Center has held numerous computer-build events since it began restoring and redistributing computers in 2001. In 2005, it received the Dell Higher Education Leadership Award to fund the collection of unused personal computers from the campus community and divert the equipment from landfills.
Also part of the Computers To Youth program is CU’s Property Services department. Other contributors have included the Community Computer Connection and Microsoft Corp.
“Hopefully this project will create additional collaboration with community groups and corporate sponsors in Colorado,” said St. Vrain School District teacher Karen Hunter, whose high school participated in Computers To Youth last year. “The students’ new-found confidence as a result of the amazing folks at CU-Boulder tells it all.”

$6 million CU-Boulder instrument to fly on Sept. 6 NASA mission to moon
Aug 29th
A $6 million University of Colorado Boulder instrument designed to study the behavior of lunar dust will be riding on a NASA mission to the moon now slated for launch on Friday, Sept. 6, from the agency’s Wallops Flight Facility in Virginia.
The mission, known as the Lunar Atmosphere and Dust Environment Explorer, or LADEE, will orbit the moon to better understand its tenuous atmosphere and whether dust particles are being lofted high off its surface. The $280 million LADEE mission, designed, developed, integrated and tested at NASA’s AMES Research Center in Moffett Field, Calif., will take about a month to reach the moon and another month to enter the proper elliptical orbit and to commission the instruments. A 100-day science effort will follow.
“We are ready and excited for launch,” said CU-Boulder physics Professor Mihaly Horanyi of the Laboratory for Atmospheric and Space Physics, principal investigator for the Lunar Dust Experiment, or LDEX. “We think our instrument can help answer some important questions related to the presence and transport of dust in the lunar atmosphere.”
One unanswered question since the days of the Apollo program is why astronauts saw a pre-sunrise glow above the lunar horizon, said Horanyi, who directs LASP’s Colorado Center for Lunar Dust and Atmospheric Studies. “The glow has been suggested to be caused by dust particles that were electrically charged by solar ultraviolet light, causing them to lift off from the moon’s surface.”
About the size of a small toaster oven, the LDEX instrument will be able to chart the existence, size and individual velocities of tiny dust particles as small as 0.6 microns in diameter. For comparison, a standard sheet of paper is about 100 microns thick. A collision between a dust particle and a hemisphere-shaped target on LDEX generates a unique electrical signal inside the instrument to allow scientists to detect individual particles, said Horanyi.
Horanyi said clouds of dust specks seemingly observed by astronauts hovering over the moon likely weren’t clouds at all. “If you watch a cement truck on the highway, it seems to be carrying a dust cloud along with it. But what is actually happening is that every speck of dirt coming off the truck is falling onto the highway,” he said.
“The specks have very short lifespans, and the cloud that appears to surround the truck is actually a continual rain of dust from the vehicle to the pavement,” he said. “Similarly, the smallest lunar dust particles could also continually lift off and fall back onto the surface.”
Knowing more about the behavior of lunar dust could be of use for future human expeditions to the moon, including potential colonization efforts. Learning more about lunar dust also might help scientists better understand dust on other moons in the solar system — like Phobos and Deimos that orbit Mars – that have been suggested by some as possible initial landing posts for crewed missions headed to the Red Planet.
LADEE also is carrying an ultraviolet and visible light spectrometer, a neutral mass spectrometer and a lunar laser communications demonstration.
Astronauts walking on the moon sank into a shallow layer of dust, thought to be a product of millions of years of meteoric and interstellar particle bombardment, he said. “The beauty of physics is that we believe the same processes occur throughout the universe,” he said. “What we see on the moon may well apply to Mercury, Phobos, Deimos or asteroids, which all have very tenuous atmospheres.”
When the LADEE spacecraft is inserted into an elliptical orbit, its closest approach will be less than 20 miles from the lunar surface. “The closer we can get to the surface the better,” he said.
“This is a very exciting mission that will answer an almost 50-year-old question in space science,” said CU-Boulder graduate student Jamey Szalay, who is writing data analysis software for the mission that will allow the team to analyze science results immediately after data is received from the spacecraft. “Given the convenient duration of the mission and promising science return, I’m very fortunate to be a part of the science team — it’s a dream project for any graduate student in space sciences to be working on.”
Horanyi also is the principal investigator on CU-Boulder’s Student Dust Counter, a simpler instrument than LDEX flying on NASA’s New Horizons mission that was launched in 2006 to explore Pluto and the Kuiper Belt, a massive region beyond the planets containing icy objects left over from the formation of the solar system. The Student Dust Counter was designed, built, tested and operated entirely by students, primarily undergraduates, at LASP and has been collecting data for the past seven years. New Horizons is now more than 2.5 billion miles from Earth and will arrive at Pluto in two years.
CU-Boulder researcher David James, who now is working on LDEX, got his start helping to build SDC. “Although I was a student in a lab back then, it was almost like working in the private sector,” said James, who eventually received his doctorate from CU-Boulder. “We were building an instrument that was going to Pluto. It was an amazing experience with huge responsibilities, it pushed us to do our best, and it definitely shaped who I am today.”
The LDEX instrument, as well as many previous LASP instruments launched into space since the 1970s, will carry a laser engraving of the CU mascot, Ralphie the Buffalo, as well as the names of all university people who participated in the project, from students and scientists to engineers and administrative support staff. “It’s like adding a touch of history to the mission, perhaps for good luck and pride,” said Horanyi. “After all, this is the University of Colorado.”
