Aaron Persad is one of 11 91�Թ� alumni named to the Canadian Space Agency’s shortlist of candidates to become Canada’s next two astronauts.

“I felt excited, honoured and a bit surprised since I knew I was competing with very highly qualified colleagues,” said Persad. “While space is big, the space community is small, and I am delighted to see that several colleagues are also in the CSA shortlist.”

A postdoctoral researcher currently working in the lab of Mechanical and Industrial Engineering Professor David Sinton, Persad is one of under consideration for two upcoming astronaut roles with the Canadian Space Agency (CSA).

He's one of five 91�Թ� Engineering alumni to make the shortlist. Other Faculty of Applied Science & Engineering alumni on the list are:

Other 91�Թ� alumni on the shortlist include:

Any alumnus or alumna picked for the program would be following in the footsteps of such 91�Թ� astronauts as alumna Julie Payette and 91�Թ� Misissauga alumna  , who took the crest of Erindale College, as 91�Թ� MIssissauga used to be known, into space with her as the first Canadian woman astronaut.

Persad’s dream of going to space began at the age of seven and his pursuit of it . During his undergraduate studies, he completed his Professional Experience Year internship at the CSA, including a flight in a Falcon-20 jet where he got experience the sensation of free-fall for the first time.

“It felt fantastic. I remember my legs had the tendency to float up toward my chest. I had to consciously keep them down,” said Persad.

Persad’s PhD research, supervised by Professor Emeritus Charles Ward, focused on solving a decades-old mystery about , specifically the shape it takes within a closed container. The seemingly simple question has important implications for life-support systems in space.

The project suffered a major setback when a SpaceX rocket meant to carry his experimental apparatus into orbit exploded in the summer of 2015. Undeterred, Persad created a new apparatus in time for the next launch in the summer of 2016. Last week, NASA astronaut performed the experiment aboard the International Space Station.

Outside of his research, Persad has been and has led a number of educational initiatives, including a company that delivers robotics technology education to young children.

This is Persad’s second attempt to become an astronaut, having applied during CSA’s previous round of recruitment in 2008, when he was a master’s student at 91�Թ� Engineering. Since then, Persad has greatly enhanced his technical expertise and aggressively pursued astronautics training through the non-profit organizations and .

“I used my previous evaluation as a checklist to prepare for a future call. For example, I was asked questions like ‘Do you have piloting experience?’ or ‘Have you ever taught a post-graduate engineering course?’” said Persad. “For the last eight years, I’ve been working hard to turn every ‘no’ into a ‘yes.’”

A final decision from is expected by June 2017.

“I know my family and friends are cheering me on,” said Persad.
