On March 17, 2017, two members of PolyOrbite (Camille and Frédéric) took part in the event “Girls and science: an electrifying duo!”. This event was organized in collaboration between École Polytechnique de Montréal and École de Technologie Supérieure (ÉTS). We are proud to have been present to promote careers in science and technology to young girls in Quebec.
PolyOrbite held a workshop where young girls built rockets that were launched with an air pump. They had access to a bin of supplies and had to use all their creativity to create a spacecraft that combined aesthetics, performance and solidity.
We also gave a presentation about our new CubeSat ORUS and our tasks in the technical society. Our positions in the Administration team allowed us to also address the management aspect of a project, in addition to the technical aspect of the satellite’s design.
After this event, Camille testified: “I loved working with such passionate young women. As they had chosen the workshops that interested them most, enthusiasm and curiosity were at the rendezvous! I hope I have succeeded in passing on some of my own passion for aerospace. ”
The comments were all very positive and we look forward to the next edition that will take place at École Polytechnique.
For PolyOrbite, sharing our passion and promoting the space and scientific fields are our values.
PolyOrbite held it’s first launch party on Wednesday, April 5th since its creation in 2013! The purpose of this party was to review what has been achieved over the past 4 years and to welcome the new iteration of the CSDC 2016-2018 (Canadian Satellite Design Challenge) with many challenges ahead.
The administrative team demonstrated an incredible sense of logistics to ensure the smooth running of the evening. First of all, the guests were welcomed including sponsors, former members and all professors involved in this project: Supervisor Professor Giovanni Beltrame (InfoLog), Sofiane Achiche (Mechanics), David Saussié (Electrical) and Fabio Cicoira (Chemical).
Among the sponsors present were MDA, CRIAQ, IICAP and CAE.
The guests were able to chat and get to know the members around small snacks and glasses of wine.
After that, Professor Giovanni Beltrame, current president of PolyOrbite Louis Attendu and previous president Constance Fodé (2014-2016) made a speech.
Giovanni Beltrame held a speech to highlight the importance of satellites today and their future.
During his speech, Louis Attendu thanked all members and sponsors who helped PolyOrbite become what it is today.
The rest of the evening, a few members took photos by team to show their motivation for the projects to come!
The other teams are: alimentation, control-operations, data, telecom.
PolyOrbite is also proud to welcome more and more female members to its large family:
Last September, PolyOrbite participated in the 67th International Astronomical Congress (IAC) in Guadalajara Mexico. The IAC regroups all the actors of the space industry and is held in a different country each year. The congress in divided into two categories of events: the technical sessions and the associated events.
It’s during the technical sessions, and more precisely within the “New Missions Enabled by New Propulsion Technology and Systems” category, that PolyOrbite presented an article on our ion thruster: “Manufacturing Compact Electrospray Thrusters to Deorbit a Nanosatellite”.
The associated events were large assemblies where industry leaders showcase their technological advancements and future projects.
This year, all eyes were on Mars. A few examples are NASA’s presentation on the objectives for their Space Launch System and the European Space Agencies’ moon village concept to replace the International Space Station after 2024. This would facilitate the transition from low earth orbit to Mars.
The most popular event was clearly the long awaited “Mars Plan” announcement by SpaceX CEO Elon musk entitled: “Making Humans a Multiplanetary Species”. The event went over the different technologies that will need to be developed to colonize Mars like massive COPV tanks, in-orbit refueling, and rapidly reusable rockets. All this in order to bring the cost of “moving to Mars” under 200 000$ USD.
This year’s AIC included a very large contingency of companies working in the emerging nanosat and CubeSat industries. An Italian company by the name of D-orbit stood out by proposing liquid and solid propulsion systems for CubeSats as well as a CubeSat dispenser capable of delivering up to 27 units of CubeSats.
With the congress now over, we can see two major stories developing in the space industry. Firstly, the race for Mars has officially started and it’s no longer a question of “if we’re going to Mars” but rather “when will we get there”. Secondly, a slow but steady decrease in price for access to space is driving many new companies out of the darkness. Cubesats are on the rise and PolyOrbite is in the middle of it all.
Next year’s IAC will take place in Adelaide, Australia, and PolyOrbite will once again be present at this amazing event to share our work and learn from others.
During the last two weeks, PolyOrbite has been working hard promoting our project and we are proud to show that our efforts have paid off.
During this event, many students were able to obtain in-depth information on PolyOrbite and CubeSats by coming to our table. While at our kiosk, many of those students also signed up for a recruitment drive that would take place on September 13th and 15th to get to know the project a little better and meet the team’s leaders. If they decided on becoming a new member of PolyOrbite, we put them to the test. The task was to find a solution, in the sub-system of their choice, to a problem relating to a sample collection problem on an asteroid that had been redirected around the moon’s orbit. This exercise allowed us to stimulate our candidate’s minds and let them familiarize themselves with the different subsystems of CubeSats.
On the 20th of September, we gathered all our prospective recruits for the final selections.
During this assembly, the team leaders presented the details of their team (structure, mission, ADCS, power, telecommunications and administration) to help the recruits in making a final choice.
Following the presentation, the recruits took to the stage. One after another, they present their CubeSat sub-system design for the asteroid sample mission that was presented during the first information session.
The whole team at PolyOrbite would like to thank all of its new recruits for their active participation and amazing concepts!
PolyOrbite, once again on the Podium !
On June 16, PolyOrbite won third place of the Canadian Satellite Design Challenge 2014-2016 and also the UrtheCast Educational Outreach Award, rewarding educational involvement with the youth and general public.
The nanosatellite named Hathor has two payloads: SpaceBean (self incubator dedicated to the germination of the plant Arabidopsis thaliana) and IonDrop (an ion engine used for de-orbit in order to reduce space debris).
During the week of June 13, the team visited the David Florida Laboratory in Ottawa to make the final tests. The goal was to create a vibration test that simulates the launch of the nanosatellite. Hathor was tested around all 3 axes, with a frequency of up to 2000Hz).
After the vibration test, team leaders conducted a series of functional tests, to show the judges that the satellite was still operational, especially:
– Sensor Acquisition
– Demonstration of the actuators
– Deployment of antennas
Followed by a series of questions from the judges about the 6 subsystems (ADCS, Power, Data handling, Mission, Structure and Telecommunication) and verification of the criterias provided in the specifications of the competition.
PolyOrbite is proud of its third place, allowing us to stay on the podium. The whole team is now already preparing the next two years with beautiful projects in mind and dreams of one day to put our nanosatellite into orbit.

Aéro Montreal celebrates its 10th anniversary with the launch of the second edition of AéroPortail, a gathering of more than 2.000 graduates, professionals and aerospace enthusiasts of all ages, wishing to find employment or training programs in the sector.
It is with pride that PolyOrbite participated in Quebec’s largest gathering of the aerospace industry to present its latest satellite: Hathor and its missions. PolyOrbite team was able to share their knowledge with experts but also with the general public to raise awareness about space issues.
It is by the same occasion that Josué Zabeau, the head of the Payload team, participated in the panel discussion on the space theme, alongside Marc Donato VP Operations Information Systems Group of MDA, a world renowned company in space technology, representing PolyOrbite as the space club of the École Polytechnique in Montreal.
IonDrop, our second payload is an electrospray thruster, a technology based on the acceleration of ions through an electric field.
The propellant is an ionic liquid confined in a porous glass tank, the liquid reaches by capillarity a nickel porous substrate which is in contact with the porous glass. This nickel part has a very thin porosity with a pore size that does not exceed 2 microns and is covered with micro emitters with a height of 100 micrometres that will be soaked with the ionic liquid.
At a distance of 300 microns, a grid drilled with micro-holes provides the magnetic field with the porous nickel emitters on the other side and lets the accelerated ions pass through the holes. This grid (250 microns in diameter and 150 microns in thickness) is one of the key parts for this thruster design because it initiates the thrust. Thus, an extremely precise manufacturing process is required to realize it.
Potomac Photonic is the partner of PolyOrbite that will make this payload possible by creating this part. The newly formed partnership between Photonic Potomac and PolyOrbite is a vary valuable one and, hopefully, it will help PolyOrbite in this and future challenges. The resulting thruster will provide a thrust of 50 micro-Newton, a really small amount on paper, but still sufficient to decelerate the satellite of 150 m/s over long periods (2 weeks or more).
Miniaturizing the electrospray thruster technology is of fundamental importance for nanosatellites because it will allow them to change their orbit and to increase the number of applications realizable with CubeSats. With an Isp of almost 3000s, these thrusters are really efficient and can perform many different tasks, from attitude control to interplanetary propulsion. The thruster design developed by PolyOrbite is specifically meant for CubeSat and it it small enough that four such thrusters can fit on one end of a small satellite.
We are getting closer to the day of the competition and we would like to introduce the SpaceBean’s incubator. We printed it in 3D, thanks to the MakerBor Replicator in the library at Polytechnique Montreal.
This incubator will be used to analyze the growth of our little seed on Earth. We will put it in the exact same environment that the other one, growing in the cubesat.
In this way, we will be able to compare and analyze the differences between the two seeds.
– Weight : 400 ± 20 g
– Size : 94 x 94 x 40 mm
– Power consumption: 0.2 to 2.5 W
– Heat power: 2 W
PolyOrbite will participate to the AéroPortail event, held in the Centre des Sciences de Montreal. We will present our new satellite Hathor and its missions: SpaceBean and IonDrop.
This event is especially dedicated to aerospace enthusiasts. Feel free to visit us at our booth at the largest event of the aerospace industry in Quebec!
In the last week of may 2014, PolyOrbite went to the David Florida Laboratory for the last evaluation in the competition, which would reveal which teams were going to be the best. We had to go through vibration tests and a final review of the satellite with the judges we had met at the Critical Design Review. On Thursday night was the announcement regarding the ranking of the teams.
For our very first edition at this competition, we are very proud to say that PolyOrbite accomplished 3rd place over the 10 canadian participating teams. Even more so when we realise that we are the only new participating school in the top 5 universities, who had over four years of experience for some. The 2nd team is SpaceConcordia, from our neigbhour university who was very supportive of us and who truly deserved this position. The winners of this Second edition of the Canadian Satellite Design Challenge are the students from the University of Victoria. Congratulations!
We are looking forward for the next edition of the competition which begins this fall!
