Living on lava: replicating life on Mars USF student spends four months on Hawaiian volcano for NASA simulation study. n

While spending time in Hawaii may seem like a vacation for some, one USF student has spent the last three months there far from comfort, isolated on the planet’s largest active volcano, Mauna Loa. On this red terrain, chemical engineering doctoral student Anne Caraccio simulates living on Mars with others chosen by Hawaii Space Analog and Simulation (HI-SEAS), a University of Hawaii organization funded by NASA. “Of course most people would not want to isolate themselves in a dome inside

a habitat on the slopes of a volcano,” Caraccio said in a video transmission to The Oracle. “But if you are passionate enough about the space program … then of course a mission like this is for you.” Kim Binsted, HI-SEAS’s principal investigator, said NASA wants to study the stress of crewmembers living together in confinement. Especially since an actual mission to Mars could possibly launch within two decades. “A crew to Mars would be together for two and a half years, so of course we want to make sure they can work well together,” Binsted said. Throughout the day, the crew fills out surveys and diaries. They also wear armbands that collect physiological data and badges that record pattern in conversation, such as tone of voice. “It gets a good idea of how we are behaving around each other,” Caraccio said.

To stay true to life on another planet, ground control sometimes creates unpredictable complications. Caraccio, for example, once removed all the waste from a broken, waterless toilet — a memorable experience, she said. “We’ve had a couple of nights where we lost power, there were a couple days where we didn’t have Internet,” she said. “I’m actually hoping with the last third of the mission that we’ll have some intense scenarios.” Though the focus of the mission is to study crew psychology, crewmembers can do their own research, such as growing vegetables for astronauts to eat on long space missions. Caraccio’s personal research is called Trash-to-Gas and aims to recycle garbage, which crewmembers sort, into an energy source for oxygen and water production. “When astronauts are currently on station, they take

trash and compress it into footballs … it’s then burned up in earth’s atmosphere,” she said. “We can’t do that in long duration missions.” Every crewmember also studies the volcano’s geology. While 8,000 feet above sea level is a bit closer than 140 million miles from Earth, the volcano’s soil is basalt, the rock of the volcanoes on Mars. Binsted said the absence of life and “visual isolation” of Mauna Loa also sets a proper Martian setting. “Living on the slopes of the volcano is very quiet,” Caraccio said. “The view is spectacular.” The landscape of cooled lava can be seen from a single window in the dining area of the 1,000-square-foot dome that houses the five crewmembers. The compact dome is crowded with research equipment and essentials. On the

STEM summer academy to inspire young science community

Only 16 percent of high school seniors are interested in pursuing a career in science, technology, engineering and math (STEM), according to the U.S. Department of Education. As the nation falls out of the top 20 rankings in math and science among industrialized nations, STEM careers are estimated to be in most demand with a workforce that is projected to increase by 14 percent in all occupations and as much as 62 percent for biomedical engineers. Last month, USF was awarded $1.2 million by the Howard Hughes Medical Institute (HHMI) to develop a summer program to cultivate a passion for STEM fields in first-year students. Scott Lewis, member of

the STEM Academy and USF research professor, said the academy would excite incoming students when it opens next year by offering a taste of what the fields of science have to offer. “I see hundreds of students engaged and talking about science,” Lewis said. “It’s really rewarding after putting in all the planning and foresight into it.” The academy will eventually serve 480 students split into 20 groups led by seniors and graduate students. Richard Pollenz, director of the STEM Academy and associate dean of undergraduate studies, said a focus on mentorships and connecting fellow students would foster a STEM community on campus. “If you think about it, there are roughly 1,100 students

coming into biology, biomedical majors,” Pollenz said. “Some of our information says they feel lost and don’t feel connected. This is going to be a way to hopefully help them feel connected early.” Students will have the option to live on the same floor of a residence hall with others who attend the summer academy as well. Along with encouraging community, Pollenz said hands-on experience would also create incentive retention, as students will receive more personalized training and tutoring in the SMART Lab. “Some of the data suggests that when you give students a dry run of how some of the learning happens that they do much better when they get into it for real,” he said. Lewis said letting students

learn research methods to explore topics of interest would prepare them for upper level college courses. “The way research works, it’s not something that happens very quickly as far as your investment in it, it takes a long time to mature,” he said. “I think that the earlier you can do research the more meaningful it’s going to be.” Most of the opportunities will focus on biology and biomedical research, which are the most popular fields for first-year students. Pollenz said 60 percent of biology students, who make up the majority of STEM freshmen, switch out of their major. “We know the statistics of what is happening, we don’t know why,” he said. “Are they leaving because they aren’t feeling inspired? If we can see a 10

or 20 percent difference, that is huge.” In the larger picture, the deficit of STEM graduates shrinks the supply of qualified workers. According to the Council of Foreign Relations, 60 percent of U.S. employees cannot find qualified workers — a statistic Pollenz said USF’s STEM program aims to change. USF was one of 37 research universities HHMI selected in a $60 million effort to improve U.S. competitiveness in science. The $1.2 million grant money is projected to end in 2019, but Lewis said USF would pay for the academy afterward. “There are so many career opportunities in science and math and the more we can get the word out that there are those opportunities and very good careers, the better,” Lewis said.
