In the early hours of August 6, 2012, a car-sized rover called Curiosity landed on Mars in the culmination of a 254-day, 350-million mile journey. The much-celebrated and nerve wracking landing captured the nation's fascination before Curiosity began its scheduled two year mission of studying the climate and geology of Mars. One former Northwestern student-athlete stayed up late to watch the landing live for a very good reason: he played a role in designing part of the Curiosity Rover.
"I
was very excited and anxious for the landing of the Rover," said Andrew Long, a
2009 Northwestern graduate who earned Capital One Academic All-America honors
as a member of the men's swimming and diving team. "I could have gone to sleep
and woke up the next day to see if the Rover survived the landing, but I
decided to stay up. So many different elements had to go correctly for the
Rover to successfully land, so it was quite exciting after each part was
announced on NASA TV."
Following
his sophomore year at NU, Long did an internship with NASA's Langley Research
Center in Virginia, where he learned that the best way to get a job with NASA
is to work with the organization as part of a cooperative education program
between a University and a specific employer. Because of his interest in
robotics, Long went to work at NASA's Jet Propulsion Lab for a total of nine
months over his final year at Northwestern. There he joined the Planetary
Sample and Handling Acquisition group, which was responsible for designing the
drill and other sample handling devices on the end of a robotic arm attached to
Curiosity.
Before
joining the program, Long was a distance freestyle specialist for the Wildcats
from 2005-08, competing in the 500 and 1,650 freestyle events at three different Big Ten Championships. After earning an Academic
All-America honor for his work in the pool and the classroom following his
junior season, Long decided to focus solely on his future career path.
"The
co-op program is not very compatible with being on a varsity swim team, so I
decided to retire from swimming after my third season to get more in-depth
engineering training," Long said.
In-depth
it certainly was. Long's role on the team consisted of independently designing
and overseeing fabrication of mass models for vibration tests of the drill,
conducting those tests to ensure the parts could withstand the forces and
vibrations of launch and landing. He also worked with rapid prototyping, a
useful tool for engineers to develop models to visualize concepts and
components of a design.
"I
became the key individual for my group for rapid prototype development of
components on the end of the robotic arm," Long said.
Since
its successful landing two weeks ago, Curiosity already has been back in the
news for blasting a Mars rock with its pulsing laser to analyze its makeup.
Similarly, the drill Long's team worked on will bore into Martian rocks and
prepare the samples to be processed and analyzed by other scientific
instruments on the rover.
Following
his graduation in 2009, Long stayed at NU in the mechanical engineering PhD
program, working in the Laboratory for Intelligent Mechanical Systems under Dr.
Kevin Lynch, conducting research on a climbing robot. Long and his wife, fellow
Northwestern alum Adrienne Smith, have since moved to Maryland where he is
enrolled in the Johns Hopkins University biomedical engineering PhD program and
she is doing pediatric oncology research at the National Institutes of Health.
"The
focus of my current PhD program is figuring out how the brain controls the body
during walking," Long said. "We have a special treadmill in our lab that has a
belt for each foot, and occasionally we change the speeds of the belts independently
to look at how the brain adapts to walking in this new pattern. We are doing
this to learn about the brain while finding out if we can use this type of
treadmill for rehabilitation of patients with damage to their brain."
