MSCA Doctoral Network position “Electric solar wind sail mission design” We are now looking for two (2) Doctoral Researchers. This PhD topic is part of the “Electric solar wind sail doctors” (E-Sailors) network, funded by the Marie Skłodowska-Curie Actions (MSCA) Doctoral Network Programme. The E-Sailors network is designed to train the next generation of Electric solar wind sail (E-sail) scientists, developers and advocates. This particular Doctoral Researcher (DR) will work with in-orbit results of on-going missions, such as Foresail-1 p developed by Aalto University with the E-sail payload from the Finnish Meteorological Institute (FMI), as well as the DR will develop new and improved in-orbit E-sail experiments for future missions in lunar orbit and deep space. The DR will be enrolled at and hosted by Aalto University, Finland, with the main supervisor Jaan Praks, co-hosted by the FMI with the E-sail researcher Dr. Petri Toivanen. Research field: Space technology, payload development Supervisor: Jaan Praks Offered by: Aalto University, School of Electrical Engineering General description of programme and host The Electric solar wind Sail doctors (E-Sailors) is a challenge-based Doctoral Network that aims to bring Electric solar wind sail (E-sail) from low Earth orbit (LEO) demonstration missions to the operational environment of the solar wind. It is delivered by 8 universities in cooperation with FMI, where E-sail was invented, and 4 companies. E-sail is a highly innovative and potentially disruptive propellantless propulsion system. An operational E-sail consists of hair-thin and kilometres-long wires, or tethers, which are charged at a high voltage creating an electrostatic sheath (electric sail) which deflects solar wind particles and generates the propulsive effect in interplanetary environment. Successful and rapid development and deployment of the technology will ensure EU's leadership in the exploration and exploitation of deep space, the next commercial space frontier. The programme is designed to achieve the following training objectives for our doctoral researchers: Equip them with core scientific skills and specialised knowledge in designing experiments for demonstrating space technologies and developing space missions; Provide them with a wide range of transferrable skills, such as Open Science and FAIR, communicating science to public, advocacy, networking etc.; Develop their business and entrepreneurship skills, such as IPR management, preliminary business planning, pitching to investors, starting start-ups. Aalto University is a leading Finnish university combining science, technology, design, and business to foster innovation and multidisciplinary research. The Aalto Space Lab is a comprehensive facility dedicated to the development, integration, and qualification of small satellites and space payloads. The laboratory features an advanced electronics development environment equipped for precision soldering, calibration, functional testing, and sensor characterization. A dedicated cleanroom area supports the assembly and integration of flight hardware, ensuring high reliability and adherence to space standards. Adjacent to the electronics lab, the Space Technology Testing Laboratory provides an advanced thermal–vacuum facility that enables environmental testing of complete satellites and subsystems under simulated space conditions. This includes vacuum, thermal cycling, thermal balance, and outgassing testing, essential for qualifying hardware for launch and orbital operation. The Space Lab also offers access to a wide suite of engineering and simulation software for electronics design, spacecraft systems modelling, structural and thermal analysis, and mission performance verification. Together, these resources support the full development cycle—from early concept design and prototyping to environmental qualification and flight readiness. The Aalto Space Lab serves as a key hub for small satellite and payload research, education, and technology demonstration, supporting academic projects, collaborative research initiatives, and industrial partnerships that advance Finland’s growing role in space technology. Description of specific PhD project Please indicate in your cover letter which of the two positions you are primarily interested in. Position 1: The E-Sailor 8 The E-Sailor 8 doctoral position focuses on developing advanced methods for E-sail tether deployment monitoring and safety, combining simulation, laboratory testing, and in-orbit validation. The candidate will create dynamical and photorealistic 3D models of the tether and spacecraft to support both engineering analysis and visual monitoring during deployment, working in coordination with the RT3D development led by E-Sailor 15. The research includes conducting laboratory and in-orbit experiments using data from the Foresail-1p mission, analysing tether dynamics, imaging, and operational behaviour. Based on these results, the doctoral researcher will propose and evaluate new deployment schemes and safety strategies, contributing to the reliability of future E-sail missions. The work will result in models and validated methods shared with the wider community to support ongoing and upcoming E-sail technology developments. Duration of the work contract and place of employment: The position is based at Aalto University (24 months) with collaboration at CrystalSpace (CS) (12 months), under the supervision of Jaan Praks (Aalto) and Jaan Viru (CS). Position 2: The E-Sailor 4 The E-Sailor 4 doctoral position focuses on the design and engineering of an electric sail (E-sail) payload system for nanospacecraft, with a particular emphasis on developing the payload for the ESTCube-LuNa mission. Building on previous demonstrations such as ESTCube-1, ESTCube-2, and Foresail-1p, the project aims to apply lessons learned to create a more capable and reliable E-sail payload. The work involves analysing previous mission data, defining requirements for new payloads, and designing the mechanical, electrical, and deployment subsystems for ESTCube-LuNa. E-Sailor 4 will also lead the development and testing of a prototype payload, performing functional and environmental tests to verify its performance and requirements for spacecraft integration. The research will result in three main publications covering lessons learned, design development, and prototype testing. In the final project phase, the doctoral researcher will spend 6 months at Spacecraft Anatomy (SA) to gain industrial experience in space hardware manufacturing and qualification. The project will deliver a E-sail payload prototype design and strengthen the technological foundation for future nanospacecraft missions using E-sail propulsion. Duration of the work contract and place of employment: The main supervisor of the DR at Aalto University, Finland (15 months) is Assoc. Prof. Jaan Praks. The DR will also be co-supervised by the E-sail inventor Petri Toivanen while working for 15 months at the FMI, Finland and by Dr. Iaroslav Iakubivskyi while working 6 months at Spacecraft Anatomy, Estonia. Additional details of the positions Starting date: The position is expected to start in the first half of 2026.
