SPCAE SECURITYMonitoring Space Traffic
AeroAstro Ph.D. student Sydney Dolan uses an interdisciplinary approach to develop collision-avoidance algorithms for satellites.
If there’s a through line in Sydney Dolan’s pursuits, it’s a fervent belief in being a good steward — both in space and on Earth.
As a doctoral student in the MIT Department of Aeronautics and Astronautics (AeroAstro), Dolan is developing a model that aims to mitigate satellite collisions. They see space as a public good, a resource for everyone. “There’s a real concern that you could be potentially desecrating a whole orbit if enough collisions were to happen,” they say. “We have to be very thoughtful about trying maintain people’s access, to be able to use space for all the different applications that it has today.”
Here on the Blue Planet, Dolan is passionate about building community and ensuring that students in the department have what they need to succeed. To that end, they have been deeply invested in mentoring other students; leading and participating in affinity groups for women and the LGBTQ+ community; and creating communications resources to help students navigate grad school.
Launching into New Territories
Dolan’s interest in aerospace began as a high school student in Centerville, Virginia. A close friend asked them to go to a model rocket club meeting because she didn’t want to go alone. “I ended up going with her and really liking it, and it ended up becoming more of my thing than her kind of thing!” they say with a laugh. Building rockets and launching them in rural Virginia gave Dolan formative, hands-on experience in aerospace engineering and convinced them to pursue the field in college.
They attended Purdue University, lured by the beautiful aerospace building and the school’s stature as a leading producer of astronauts. While they’re grateful for the education they received at Purdue, the dearth of other women in the department was glaring.
That gender imbalance motivated Dolan to launch Purdue Women in Aerospace, to facilitate connections and work on changing the department’s culture. The group worked to make study spaces more welcoming to women and planned the inaugural Amelia Earhart Summit to celebrate women’s contributions to the field. Several hundred students, alumni, and others gathered for a full day of inspiring speakers, academic and industry panels, and networking opportunities.
