The Launching Pad: Systems Check
Third in a series of dispatches from the BU nanosatellite team
This summer, while many college students are heading to the beach, some BU students are heading to space. More than 60 undergraduates are designing and building BU’s entry in the University Nanosatellite Program, a U.S. Air Force-sponsored competition, and about half of them are working through the summer.
Every other year, the Air Force Office of Scientific Research gives about 10 university teams the chance to design and build a satellite, and guarantees the winners a launch. The BU satellite is intended to hover over the aurora borealis, known as the northern lights, which are produced when particles from radiation belts thousands of miles out in space interact with the Earth’s atmosphere. The measurements and images taken by the satellite would test and enhance an existing computer model of these auroras, part of an effort to better predict violent space weather that can damage spacecraft electronics and disrupt communication networks such as pagers and cell phones.
The project is overseen by Theodore Fritz, a College of Arts and Sciences professor of astronomy, a handful of other professors, and doctoral student David Voss (ENG’09). But the design, the engineering, and the presentations will be completed by the undergrads. They are working in about a dozen teams on the satellite’s different subsystems, such as the probes and imaging equipment, the ground control station that will be housed at BU, and the orbital adjustment system. BU Today will check in on their progress as they prepare to face a panel of Air Force, NASA, and industry satellite experts in a preliminary design review on August 17.
Last month, we featured Kyle Winters (ENG’09), who’s helping to build the solar arrays that will power the satellite and also working on the project’s required educational component, a curriculum to teach local high school students how to build a satellite’s thermal probe. We also heard from Jeannette Hancock (ENG’08) whose “attitude” subsystem team is designing a system to keep the satellite’s probes and sensors pointed in the right direction as it orbits.
In this installment, we check in with Fabio Malangone (ENG’09) who’s working with the ground support equipment team. Their task: to inspect, test, calibrate, adjust and repair every system that will come together in the nanosatellite. Once the satellite is built, it will be crammed with delicate instrumentation and will weigh more than 100 pounds. It will be the responsibility of Malangone’s team to move the craft from place to place.
The preliminary design review is just over a week away, but Malangone notes this is just a first step toward the group’s ultimate goal. “It’s a long ways out,” he says. “But I believe that with our team I’m fairly confident that we’ll have a working satellite by the end of next summer.”
