CU alumnus heading to the International Space Station
Mar 20th
But this time he will not be riding in the familiar confines of a NASA space shuttle — the fleet was retired in 2011 — but in a capsule atop a Soyuz TMA-12 rocket launching from the Baikonur Cosmodrome in Kazakhstan. Not only will he blast off from there, he is slated to land in the capsule, which is somewhat similar to a NASA Apollo capsule, on the steppe of Kazakhstan in September after spending roughly six months in space.
Swanson, who earned a bachelor’s degree in engineering physics from CU-Boulder in 1983, will serve as flight engineer for Expedition 39, which already will be underway on the ISS when he arrives. In late May, Swanson, who considers Steamboat Springs, Colo., his hometown, will become space station commander as Expedition 40 begins.
Swanson will be launched to the ISS along with cosmonauts Alexander Skvortsov and Oleg Artemyev of the Russian Federal Space Agency.
“We’ve trained extensively and I’m confident I can do all of the tasks assigned to me on the space station,” Swanson said. “The difficult part is being away from my family and friends for a long period. I’ll miss them, but at the same time we will be very busy up there, which makes the time pass quickly.”
The astronaut crew will be involved in dozens of research experiments in the low gravity of the ISS, including efforts related to protein crystal growth, capillary blood flow, gravity sensing by plants and muscle and bone loss changes in space.
As part of his duties, Swanson will operate hardware developed by BioServe Space Technologies located in CU-Boulder’s aerospace engineering department to conduct two experiments on the space station, both being launched later this year. One led by Dr. Timothy Hammond of the Department of Veterans Affairs will use a yeast-based assay system to evaluate known and novel anti-cancer drug therapies in the low gravity of space. A second led by Professor Cheryl Nickerson of Arizona State University will evaluate host-pathogen interactions to better understand the risk of in-flight infections by space explorers during long-term missions.
Swanson previously flew on the STS-17 mission aboard the space shuttle Atlantis to the ISS in June 2007, then flew again on the STS-19 mission aboard Discovery in March 2009. Swanson spacewalked for more than 26 hours during the two missions and is tentatively slated for two more spacewalks during Expedition 39 and Expedition 40.
What does Swanson, whose two shuttle landings were on a smooth NASA runway in Florida, think about drifting by parachute in the Soyuz space capsule on the way from the space station back to Earth, eventually banging onto the ground in Kazakhstan? “I know this landing will be much more wild and exciting than a shuttle landing,” he said. “It is going to be a very different experience, and I’m looking forward to it.”
Swanson will be packing several CU mementos, including a T-shirt, a flag and a small piece of sandstone from the engineering center that has been engraved with a picture of Ralphie the Buffalo and an image of the International Space Station.
What does he recall about his time at CU-Boulder? “I remember waking up and seeing the mountains right there,” he said. “It was a beautiful thing, and helped me get going every day. I really liked CU-Boulder — it is a good school, with good professors — and I love to ski, I love to hike. I like the culture.”
His favorite times on the space station? “One of the best things is when you have a moment to yourself where you can just look out the window,” he said. Swanson also said he will spend what little free time he has emailing with family and friends back on Earth, blogging about his space station experiences and hopefully participating in a Google Hangout, sharing messages and photos and video-chatting with CU-Boulder students.
Eighteen CU-Boulder astronaut-affiliates have flown 47 NASA space missions beginning with Scott Carpenter in 1962.
Former NASA astronaut Jim Voss, who received his master’s degree in aerospace engineering sciences from CU-Boulder in 1974, currently is a CU-Boulder Scholar in Residence. Former NASA astronaut Joe Tanner currently is a senior instructor in aerospace engineering.

Space flight to test antibiotic’s effectiveness
Jan 3rd
education project on ants to space station
NASA Television will provide live coverage of the launch of Orbital Sciences Corp.’s commercial Cygnus spacecraft on Tuesday, Jan. 7 from NASA’s Wallops Flight Facility in Virginia, which will be carrying two University of Colorado Boulder payloads to the International Space Station.
The two CU-Boulder payloads — a biomedical antibiotic experiment and an educational K-12 experiment involving ant behavior in microgravity — are slated to be launched aboard Orbital Sciences Corp.’s Antares rocket at 11:55 a.m. MST. Both experiments were designed by BioServe Space Technologies, a NASA-funded center in CU-Boulder’s aerospace engineering sciences department.
The CU-Boulder biomedical experiment was designed to test the effectiveness of antibiotics in space. Past experiments by CU-Boulder and other institutions have shown bacterial susceptibility to antibiotics is significantly reduced during spaceflight, although the reason is not yet known, said CU-Boulder Associate Professor David Klaus, principal investigator on the project.
Klaus said the investigation will examine changes in the gene expression of the bacteria E. coli during exposure to different concentrations of antibiotics while in the microgravity environment of space. The hope is to locate particular genes that are key to resisting antibiotics, which could lead to improved testing on Earth as well as new drug targets or new approaches to understanding antibiotic resistance in certain diseases or infections, said Klaus.
“Previous studies carried out in microgravity have shown that bacteria are able to grow in what normally would be an inhibitory concentration of the antibiotic,” said Klaus. “This investigation is aimed at characterizing the genetic basis for this response in the weightless environment of space with the intent of applying any insight gained toward combating the increasing emergence of drug-resistant pathogens here on Earth.”
Co-investigators on the project include BioServe Director Louis Stodieck, a research professor in aerospace engineering, and Shawn Levy, a researcher at the HudsonAlpha Institute for Biotechnology in Huntsville, Ala. The research effort also involves CU-Boulder doctoral candidate Luis Zea.
Bacterial resistance to antibiotics kills 100,000 Americans every year and represents a roughly $20 billion expense to the U.S. government in excess health care costs, said Klaus. The experiments will be undertaken using spaceflight test tubes contained in the Commercial Generic Bioprocessing Apparatus, or CGBA, an automated, suitcase-sized incubator, all designed and built by BioServe.
The second experiment launching to ISS is known as Ants in Space, which examines foraging patterns based on the density of the common Pavement Ant, said BioServe Business Development Manager and Education Program Director Stefanie Countryman. “Past experiments by Professor Deborah Gordon, principal investigator on this project, have shown that some ant species have the ability to search areas collectively without individual communication. When ant densities are high, each ant thoroughly searches one small area in a circular, “random” walk, she said. When ant densities are low, each ant searches by walking in a relatively straight line, allowing it to cover more ground.
“Ants assess their own density at the rate at which they meet,” said Countryman, who said the eight individual ant habitats on ISS will be loaded with roughly 100 ants each. “The experiment examines whether in microgravity ants will use the rate at which they meet to assess density, and so use straighter paths in the larger habitat areas. The results will be compared to ground controls, which in this case will include ant habitats in hundreds of K-12 classrooms around the world.”
Countryman has previously directed BioServe K-12 education experiments involving the behavior of butterflies, ladybugs and spiders in space, reaching hundreds of thousands of students around the world in the past two decades. For the ant experiments, BioServe is partnering with the Baylor College of Medicine’s Center for Education Outreach, a longstanding BioServe partner that has developed the education curriculum guide for the experiment.
BioServe research partners on the ant project include Gordon of Stanford University and Associate Professor Michael Greene of the University of Colorado Denver. The experiment is sponsored by NASA’s National Lab Education Office as well as the Center for the Advancement of Science in Space, a nonprofit group headquartered in Cape Canaveral, Fla.
Teachers interested in participating in the ant experiments may contact Countryman at countrym@colorado.edu. More information on the project for teachers and students will be online beginning in mid-January at http://www.bioedonline.org.
The flight will be the first Cygnus resupply cargo mission launched to ISS by Orbital Sciences Corp. and follows the earlier, successful launch of a Cygnus demo flight to ISS that arrived at the orbiting station Oct. 22.
In the past 25 years, BioServe has designed, built and flown microgravity life science research experiments on more than 40 space missions. BioServe has a full suite of space flight hardware, both on ISS and on the ground, which supports its own research as well as research conducted by its customers and partners. Past BioServe partners include large and small pharmaceutical and biotechnology companies, universities and NASA-funded researchers.

CU engineering students are now NASA rocket scientists
Jun 23rd
The program allowed more than 120 students and educators from around the country to delve into the world of rocket science June 15-21 during Rocket Week at NASA’s Wallops Flight Facility on Virginia’s Eastern Shore. All participants — including 10 CU-Boulder students — were present for a sounding rocket launch carrying various experiments developed by students that successfully lifted off June 20 at 5:30 a.m. EDT.
Activities during the week included a “RockOn!” workshop for 50 university and community college-level participants led by Chris Koehler, director of the Colorado Space Grant Consortium, or COSGC. RockOn! introduces participants to building small experiments that can be launched on suborbital sounding rockets and supports a national program known as STEM that uses classes in science, technology, engineering and mathematics to improve the nation’s competitiveness in technology.
“Working with NASA, we have developed a step approach to expand the skills needed for students to enter careers in STEM,” said Koehler of CU-Boulder’s aerospace engineering sciences department. “RockOn! is the first step, followed by RockSat-C and then RockSat-X. Each step is technically more challenging than the previous one, allowing the students to expand the skills needed to support the aerospace industry.”
The RockOn! participants built standardized experiments that were launched Thursday on a NASA Terrier-Improved Orion suborbital sounding rocket. The 35-foot-tall rocket flew to an altitude of about 75 miles. After launch and payload recovery, the participants began conducting preliminary data analysis and discussing their results.
Nine custom-built Rocksat-C experiments, developed at universities that previously participated in a RockOn! workshop, also flew inside a payload canister on the rocket, said Koehler. About 50 students who designed and built the experiments attended Rocket Week.
Also attending were university participants in RockSat-X, said Koehler. They are previous Rocksat-C participants who flew six custom-built experiments aboard a sounding rocket from Wallops in August.
COSGC is a statewide organization involving 17 colleges, universities and institutions around Colorado and is funded by NASA to give students access to space through innovative courses, real-world, hands-on telescope and satellite programs, and interactive outreach programs, said Koehler.
COSGS is one of 52 space grant consortia in the nation — including Puerto Rico and the District of Columbia — and is one of the most active, having flown scores of payloads on high-altitude balloons, sounding rockets and even space shuttles, giving thousands of undergraduates and graduate students a taste of space research since the program began in Boulder in 1989, said Koehler.
The week’s activities also included activities by the Wallops Rocket Academy for Teachers and Students, or WRATS, for a high school audience. The rocket programs at Wallops continue NASA’s investment in the nation’s education programs by supporting the goal of attracting and retaining students in STEM disciplines critical to the future of space exploration.
The RockOn! and WRATS workshops are supported by NASA’s Sounding Rocket Program. RockOn! also is supported by NASA’s Office of Education and NASA’s National Space Grant College and Fellowship Program in partnership with the Colorado and Virginia Space Grant Consortia.
