Engineering students building nanosatellite
By Jamie Karras
When it comes to money, $100,000 may seem like a lot. But to Utah
State University students building a satellite, it seems like pocket
change.
The Air Force Office of Scientific Research (AFOSR) has provided 13
universities from all over the United States with that amount to design
and fabricate a satellite. The schools will be completing against each
other to see which will get to send its satellite on a free ride to
space, said Joel Quincieu, a master's student at Utah State University
and program manager supervising 30 other engineering students working
on the satellite, dubbed USU Sat II.
In the grand scheme of things, however, this amount is minimal compared
with what a project like this really costs.
"It's like someone giving you $20 to buy a BMW," said Quincieu.
"You probably wouldn't even make it to the store."
Quincieu said that if a professional group were to build the same thing,
it would probably cost between $2 million and $3 million. This means
that the team members will be building a majority of the hardware themselves
to help reduce costs and relying on grants for the rest.
Two years ago USU participated in a similar project called USU Sat
I. This spacecraft was one of three being designed for the Ionospheric
Observation Nanosatellite Formation. The University of Washington and
Virginia Polytechnic Institute built the two other spacecrafts. These
individual crafts would be stacked and launched together. Upon arrival
in ionosphere they would separate. Before completion however, money
for this project ran out and the project was forced into a sleep mode
until more funding is available, said Quincieu.
USU Sat II will be using some electronics and software from USU Sat
I, said Quincieu.
Forty years ago there was a lot of money being dumped into the space
program; now, however, budgets have become tighter. There is a need
for new employees, but training them is expensive. AFOSR, NASA Goddard
Space Flight Center, the American Institute of Aeronautics and Astronautics
and the Air Force Research Laboratory – Space Vehicles Directorate
implemented this program as a way to provide future work force training
to students, said Dr. Charles Swenson, principal investigator and mentor
of the USU Sat II team.
Since Space Flight 1010 isn't a class offering, this program is a way
to prepare students for employment in various space fields, said Swenson.
Building a satellite that does something other than just beep is the
main goal.
"Being able to work on a real mission is rare," said Quincieu.
It is very difficult and expensive to get specific training, so this
is a huge opportunity for the students involved.
In February, the team began its attempt to hit a two-year deadline
to design, built and test a nanosatellite. A nanosatellite is a tiny
satellite, about the size of a 19-inch color television, said Quincieu.
The satellite will study and measure the ionosphere, a region of the
Earth's atmosphere that plays an important role in protecting the planet
from the sun's harmful radiation, said Quincieu.
The team includes graduate and undergraduate students working on a
volunteer basis from many nations, including Switzerland and India,
who are studying in both electrical and mechanical engineering, reported
the Herald Journal. The electrical students work with the computers,
battery power, and basically the brains of the satellite; while the
mechanical students are involved with the structure and engineering
portion.
"The electricians must consult with the mechanics or we might
have a problem," Quincieu told USU Media Relations. "It's
a lot like marriage. We have to go to each other with every little design
change we implement. We can't go off and do our own thing."
A launch goal date Quincieu says would be sometime in 2006.
