The Eirballoon is launching today. Watch live!

The Eirballoon project is part of the NANOSTAR project and the 100th anniversary of the ENSEIRB-MATMECA engineering school, based in Bordeaux (France), partner of the NANOSTAR consortium. A team composed of five students from the ENSEIRB-MATMECA engineering school will launch a sounding balloon to take pictures of Bordeaux from the sky and measure properties of […]


Health check to a reaction wheel

With the support of NANOSTAR, our partner Universidade da Beira Interior (UBI, Portugal) is now developing a student CubeSat project called CUBISat. The objective is to develop a 1U CubeSat technology demonstrator for an Attitude and Dynamics control System. Magnetic attitude determination and control devices are one of the cheapest most reliable, small and lightweight attitude systems. […]


Analysis of Orbital Relay Stations for Orbital Energy Accumulation

Design of a set of orbital platforms to raise and lower the orbit of nanosatellites efficiently without using propellant, as a major piece of infrastructure for a space-based nanosatellite economy. Author: Juan José García Ortiz University Carlos III Madrid (Spain) Space activities and attainability are constrained nowadays due to the high cost of rocketry employed […]


Design and development of a micro-PPT Thrust Balance

Design and fabrication of a thrust balance to measure a pulsed plasma thruster thrust force. This permits to verify the operation of the developed PPT thruster and identify potential improvements. Author: Andrés Cabello López University Carlos III Madrid (Spain) A design of a torsional thrust stand has been developed to test a µPPT at Carlos […]


Attitude Determination

Author: Hugo Miguel Martins Marques Instituto Superior Técnico, Lisboa (Portugal) The Attitude Determination and Control System (ADCS) of a nanosatellite is a key subsystem to provide precise attitude knowledge and pointing for the on-board payload and necessary maneuvers. Its design has serious constraints in terms of mass, volume, size, cost and power. The main goal […]


Greenhouse on Mars

Setup of a plant growing system, with the goal of testing growing strategies with A.I. (with uncertainty and machine learning). In fact, plant growing is a repetitive and time-consuming task, which can be automated to some extent, saving space, optimizing resources and reducing pesticide use. ISAE-SUPAERO (France) Implementation on real robotic systems (e.g. sensors and […]



Development of antennas, supported by the Astre’nogs association, that will be part of an open source global network of satellite ground-stations named SatNOGS and made available to the scientific community. The final outcome is an antenna what can receive both UHF and VHF frequencies. ISAE-SUPAERO (France)


Development of an inertia morphing nanosatellite prototype

Design, analysis and manufacturing of an inertia morphing nanosatellite prototype, capable of controlling a less than 5 seconds periodic Dzhanibekov’s effect. University Carlos III Madrid (Spain) The final outcome is a prototype that could be tested in microgravity conditions using parabolic flight, incrementing the TRL of this technology. The Dzhanibekov’s effect, or tennis racket theorem, […]


Vacuum chamber refurbishment for vacuum testing

Refurbishment of an unused vacuum chamber for nanosatellite components testing under vacuum conditions (in accordance to ECSS  standards). The activities include the design and fabrication of a support structure for the vacuum chamber, the definition and purchasing of all necessary chamber components and the vacuum testing of a nanosatellite component. University Carlos III Madrid (Spain)


Study of different mechanisms for the deployment of solar panels

Design of deployment mechanisms that manage to reduce the amount of energy that, during deployment, is transmitted to the solar panels. The most common mechanisms in the deployment of panels are studied, as well as dealing with this problem, to choose the ones that best adapt to the requirements. Less conventional mechanisms, unusual in satellites […]
