Measurements of emissions (gas and particles) during propulsion tests at the EPFL Rocket Team
Supervisor: eSpace, Mathieu Udriot / Prof. Jean-Paul Kneib
Type of Project: Semester project, 1 student
Duration: 14 weeks
Submission of final report: TBD in June 2025
Final Presentation: TBD
Recommended: This project is suitable for a student interested in the space industry, propulsion systems, sensors, and test benches (set-up), data acquisition, and atmospheric impacts. Prior knowledge in data acquisition or measurement is a plus.
CONTEXT
eSpace is actively researching and developing methods and products in space sustainability. This large topic includes work on space debris risks, life cycle assessment of space systems, mitigations of environmental impacts, and decision-making support tools to include sustainable aspects in the early design phase of space missions and systems.
The assessment of the environmental impacts of rocket engine exhausts in the atmosphere is not yet backed by solid scientific knowledge. There is no accepted method to translate the emission of a given amount of exhaust species (like CO2, CO, H2O, HCl, black carbon, or else) at high altitude into an impact (like CO2 equivalent). What can be done already is to quantify the emissions of propulsion systems, so as to understand which particles and gases are generated and exhausted by the engine and in what quantity during tests.
Jamie D. Shutler et alli, “Atmospheric impacts of the space industry require oversight”, (August 2022), in: Nature Geoscience, volume 15, p. 598–600, www.nature.com/naturegeoscience.
The EPFL Rocket Team is developing and testing new propulsion systems, with engines using different types of propellant, and based on new design, in preparation for its future rockets. The medium-term goal of the ERT is to fly to 100 km altitude.
It is important for the EPFL Rocket Team to understand their student-developed engines, not only in terms of performance but also regarding emissions. Knowledge about the content of the exhaust could drive future development to select different types of propellant, change mix ratio or other design parameters.
The topic is and large companies in Europe. Many are interested in measuring emissions of their engines during ground tests and directly in the atmosphere, to understand the chemistry that takes place at different altitude level. Several projects are ongoing or will soon start, through ESA or directly with industrial entities.
PROJECT SCOPE
The main goal of the project is to prepare a measurement campaign of the exhaust gases and particles generated by rocket engines used by the EPFL Rocket Team.
The test bench used by the team will require adaptations to accommodate sensors needed for the measurements. The measurements can possibly be carried out during ignition tests, and static fire tests.
It is also in the scope to investigate the feasibility to conduct another test campaign during low altitude launches by the EPFL Rocket Team.
OUTCOME
- A report including
- The state-of-knowledge regarding launchers’ exhausts.
- The state-of-affair regarding sensing method for the species of interest.
- A list of selected gas / particle sensors and measurement instruments adapted to the task.
- Computer-Aided Drawings of the ERT’s test bench adaptations, needed for exhaust measurements.
- Recommendations for future studies.
- A comprehensive test procedure to conduct a measurement campaign.
- (optional, if time allows) Results of some measurements made on the ERT propulsion system, in a format easy to use for future students.
TASKS
Phase 1:
- Literature review on launchers’ exhausts depending on their propulsion type.
- Searching for the best suited sensors to perform measurements of interest.
Phase 2 (after ordering some sensors):
- Drawing CAD adaptation for the test bench.
- Writing a test procedure to use for a measurement campaign.
- Implement changes on the test bench (and if time allows, perform sets of measurement using the sensors).
Phase 3:
- Searching for the best suited sensors and measurement scenario(s) to perform in-flight data collection of emissions of interest. Ideas include but should not be limited to: on-board sensors, air balloons, second rocket with sensors, satellite imaging, etc.
- Deeper investigation and systems architecture for a subset of selected potential solutions.

STATUS OF THE PROJECT
Life Cycle Assessment and Ecodesign applied to Exotrail’s SpaceVan
Supervisor: eSpace, Mathieu Udriot / Prof. TBD depending on university
Type of Project: Internship or Master project in industry, 1 student
Duration: ~6 months, depending on type and university
Submission of final report: TBD in March 2025
Final Presentation: TBD
Recommended: This project is suitable for a student interested in the space industry, satellite design, and environmental impacts mitigations. Prior knowledge of systems engineering, design in any engineering topic is a plus. Knowledge or experience with Life Cycle Assessment and Eco Design is an asset, but not mandatory.
CONTEXT
eSpace, is actively researching and developing methods and products in space sustainability. This large topic includes work on space debris risks, life cycle assessment of space systems, mitigations of environmental impacts, and decision-making support to include sustainable aspects in the early design phase of space missions and systems.
eSpace is now working for an ESA project called REACT with a consortium that includes IRS Stuttgart, and ISAE SUPAERO. The project will see the development of a simplified and space-specific tool for rapid life cycle assessment (LCA) of future space systems. The goal is to be able to run an analysis of the environmental impacts early in the design phase to provide valuable results to support decision-making for ecodesign when it is still possible and affordable. Ecodesign is a process to modify the architecture and design choices in order to mitigate the identified environmental hotspots.
eSpace is in contact with several companies that are interested in testing the methodology with their own mission.
One of them, Exotrail, is based in Massy and Toulouse (France), developing spacevan™ to address space logistics. In particular the spacevan™ is able to transfer satellites from GTO to GEO and deorbit satellites in Low Earth Orbit.
The spacevan™
PROJECT SCOPE
The intern or master project student would help the company in their development of future spacevan™ by assessing and improving the environmental impact of their products, throughout their entire life cycle. They would also act as a privileged point of contact within the company, to support the research and tool development of the REACT consortium.

STATUS OF THE PROJECT
Space Logistics Optimisation – Python software development
Supervisor: eSpace (Mathieu Udriot/Prof. Jean-Paul Kneib)
Type of Project: Master project, 1 student
Duration: 17-25 weeks
Submission of final report: TBD in 2025
Final Presentation: TBD
Recommended: This project is suitable for a student interested in the (new) space industry, future mission designs and operations, and who is top of the class in python coding, and familiar with object-oriented programming. Familiarity with the use of Github is a plus.
CONTEXT
eSpace is actively researching and developing methods and products in space sustainability and logistics. This large topic includes work on space debris risks, life cycle assessment of space systems, space logistics optimisation, trade-offs support and decision-making support that include sustainable aspects in the early design phase of space missions and systems.
The Technology Combination Analysis Tool (TCAT) has been developed at EPFL for ESA to model and simulate space logistics scenarios. The inputs are high level mission parameters that are available early on during design phases. Outputs help users select the best mission architecture to fulfil the mission’s objectives, and help identify technology gaps.
The tool right now can model two logistics scenarios, active debris removal of failed satellites and constellation deployment. Additional scenarios of on-orbit refuelling and interplanetary missions have been developed.
The Department of Space Launcher Systems Analysis (Systemanalyse Raumtransport; SART) at the DLR Institute of Space Systems is responsible for the design and analysis of launcher systems. Areas of research include, not only spacecraft design, but also the design and analysis of propulsion systems. The ability to integrate the study of spacecraft and thrusters in this way places SART in a unique position within Germany.
The student will spend ~8 weeks in Bremen to work closely with DLR SART on the topic, test their tools and understand the synergies that can be exploited with TCAT.
PROJECT SCOPE
The scope of this project includes the clean-up of the “modules” structure in the code to be able to perform design optimization loops from mission constraints (only possible reversely for now).
Modules are objects in the code that model subsystems of the in-space transportation system and their parameters (mass, power needs, etc.). Right now, three of those are used in the simulations: the propulsion module, the structure module, and the capture module (the latter is used for active debris removal capture systems or for modelling a dispenser).
Other modules exist in the code (e.g. AOCS, thermal, EPS) but their files are not usable and not used in the simulation yet.
Having modules describing all the subsystems of a spacecraft will allow more precise modelling and will open new opportunities for design optimization.
OUTCOME
- A report
- A branch on Github with model improvements, adaptation to the software, or new features
- An updated UML diagram
TASKS
Phase 1 (at EPFL, ~1 month):
- Familiarisation with the current version of the tool (online and of the python code).
- Literature review of subsystems of a spacecraft, and models.
- Encapsulation of the proposed changes and identification of file to modify.
Phase 2 (at EPFL, ~3 months):
- Implementation of the changes (defined with the project supervisor after the first phase) to TCAT on a new GitHub branch.
- Clean-up of the modules’ files.
- Start defining the “reverse TCAT” loop: using TCAT with its current outputs as inputs to compute preliminary sizing of future space systems.
- Start documentation in parallel.
Phase 3 (at DLR SART, ~2 months):
- Tests with DLR tools, to understand their existing capabilities in space logistics simulation, stage / spacecraft preliminary sizing.
- Identification of potential compatibility between TCAT and other tools.
- Continue on the implementation of the code and the documentation.

STATUS OF THE PROJECT
Develop a novel orbit fitting routine
Supervisor: eSpace/LASTRO (Prof. Jean-Paul Kneib/Stephan Hellmich)
Type of Project: Semester project (TP4b)
Duration: 14 weeks (Official start/end date: February 17-May 30)
Submission of final report: June 16
Final Presentation: TBD
Recommended: This project is suitable for a student interested in orbital mechanics and numerical integration. Prior knowledge in Python is a plus.
CONTEXT
As part of the newly established Space Sustainability Hub (SSH) at eSpace, we are exploring novel techniques for determining the rotational and physical properties of space debris. For this purpose, we are currently developing methods for the detection and extraction of space debris observations from large astronomical data archives. These archives contain observational data over a 10-year period and include a large amount of random satellite and space debris observations. On the astronomical images, these objects appear as characteristic streaks, most of which cross the entire detector during the several minutes of exposure time. To identify the object that caused the streak, the observations are correlated with publicly available catalogs of satellites and space debris. However, due to uncertainties in the cataloged orbital elements, propagation errors and the fact that the real orbits are constantly changing, the observation does not precisely match the cataloged orbit. In order to determine the precise observation time, the orbits from the catalogs need to be fitted to exactly match the observation.
PROJECT SCOPE
The goal of this project is to develop an orbit determination method that does not rely on exact observation time stamps, but rather treat the observation time as a variable during the fitting process. Existing orbital mechanics libraries such as Orekit contain sophisticated orbit determination and fitting routines. These methods however account only for errors in the astrometry (the measured position of an orbital debris particle in the sky) and not for uncertainties in the observation time. Due to the high spatial resolution of the images, the astrometry is very accurate but for the objects that cross the whole field during the exposure, the exact exposure time is unknown. In order to be able to fit the orbits of the identified objects to the observations, the uncertainty in the timing needs to be considered.
TASKS
- Familiarize yourself with the Orekit orbital dynamics library
- Develop a tool to fit a refined orbit from multiple orbits or observations of the same object
- Design and implement a method that fits the refined orbit to a streak, taking into account the uncertainty of the observation time

STATUS OF THE PROJECT
Enabling the Sauverny Observatory for space debris observations
Supervisor: eSpace/LASTRO (Prof. Jean-Paul Kneib/Stephan Hellmich)
Type of Project: Semester project (TP4b)
Duration: 14 weeks (Official start/end date: February 17-May 30)
Submission of final report: June 16
Final Presentation: TBD
Recommended: This project is suitable for a student interested in the software design of autonomous observatories and space surveillance and tracking with a background in software engineering. Prior knowledge in Python is a plus.
CONTEXT
eSpace and LASTRO are currently expanding their observation capabilities for physical characterization of space debris. With TELESTO, a 60 cm telescope located at the Sauverny observatory, EPFL has access to suitable observing equipment. However, in its current state, the telescope is not very well suited for the observation of space debris as the control software does not allow tracking objects in Low-Earth orbit. To overcome these problems, the telescope control software needs to be improved. This can be achieved by an open loop control system that commands the telescope based on the orbital elements of the space object that should be tracked.
PROJECT SCOPE
During the project, you will familiarize yourself with the telescope and its software environment. You will learn about the requirements of passive optical observations of space debris. In order for the telescope to be used for space debris observation, the control of the various subsystems of the facility needs to be integrated into an easy-to-use interface through which pointing and tracking of the telescope is done based on the orbital elements of the object to be observed. Since the capabilities of the telescope such as maximum tracking speed, tracking accuracy, response time and maximum rotation rate of the dome are not known, tests to find these constraints need to be performed in order to determine which objects can be reliably observed.
TASKS
- Familiarize yourself with the telescope and the software interface
- Develop a tool that controls the telescope based on the orbital elements of a space object
- Perform tests to determine the limitations of the telescope

Space Situational Awareness in cislunar space
Supervisor: eSpace/LASTRO (Prof. Jean-Paul Kneib/Stephan Hellmich)
Type of Project: Semester project (TP4b)
Duration: 14 weeks (Official start/end date: February 17-May 30)
Submission of final report: June 16
Final Presentation: TBD
Recommended: This project is suitable for a student interested in astronomy and space sustainability.
CONTEXT
After almost five decades have passed since the last human set foot on our satellite, the moon has once again become the focus of various activities in recent years. Several public and private initiatives for the exploration and exploitation of the moon are in the planning stage. Once they are realized, they will contribute to a significant increase of traffic in cislunar space over the coming decades. In order to organize traffic to and around the moon, to ensure the safety of future missions and, above all, to prevent the pollution of cislunar space as we find it in Earth orbit, strategies and infrastructures for monitoring this traffic must be created. Although most likely a space based surveillance network will be established, ground based telescopes will always be necessary to complement the observations. We plan to use the 0.6m TELESTO optical telescope at the Observatory of Geneva for cislunar SSA. The telescope was recently upgraded with a new high performance CMOS detector that enables observations of man made space objects in Earth’s orbit and beyond. Our goal is to establish an observation program to support lunar SSA.
PROJECT SCOPE
During the project, you will identify objects that are observable with TELESTO from databases of known objects in cislunar space. Tools to compute ephemeris of these objects need to be developed in order to schedule the observations. Finally, you will perform test observations with TELESTO to evaluate its capabilities in order to establish an observation program of objects in cislunar space.
TASKS
- Identify observable targets in databases of known objects in cislunar space (e.g. moondb or the NEOCP)
- Implement routines to observe these objects with TELESTO
- Perform test observations and orbit determination

STATUS OF THE PROJECT
Correct the rolling shutter effect of the new TELESTO CMOS detector
Supervisor: eSpace/LASTRO (Prof. Jean-Paul Kneib/Stephan Hellmich)
Type of Project: Semester project (TP4b)
Duration: 14 weeks (Official start/end date: February 17-May 30)
Submission of final report: June 16
Final Presentation: TBD
Recommended: This project is suitable for a student interested in astronomy and optical instrument design.
CONTEXT
The 0.6m TELESTO optical telescope at the Observatory of Geneva was recently upgraded with a new CMOS detector. The instrument uses a rolling shutter which results in the time of exposure not being the same for each pixel in the acquired image. While this effect is not important for most applications, it needs to be considered for example for space object observations, where knowledge about the precise timing is very important to determine the orbit or to perform photometric analysis. The characteristics of the shutter were already identified in a previous project. This project aims to develop a technique to correct for the rolling shutter effect for observations of fast moving objects.
PROJECT SCOPE
During the project, you will familiarize yourself with the new detector and learn about requirements of passive optical observations of satellites and space debris. In order for the camera to be used for space debris observation, the rolling shutter effect needs to be corrected for. Based on previous work where the line readout speed was determined, a method needs to be implemented that determines the precise start and end of exposure for each pixel of the detector. This method needs to account for trailed observations (where the positions of the stars on the image remain constant over the exposure) and tracked observations (where the stars move across the detector while exposing). To verify the correction, you will use TELESTO with the new detector to perform test observations of satellites in Low Earth Orbit (LEO), apply the shutter correction and verify the astrometry derived from the images.
TASKS
- Familiarize yourself with the hardware and software interfaces
- Implement routines to correct the shutter effect
- Perform observations of satellites in LEO
- Verify the shutter correction

STATUS OF THE PROJECT
Develop a weather monitoring system for the observatory of Geneva
Supervisor: eSpace/LASTRO (Prof. Jean-Paul Kneib/Stephan Hellmich)
Type of Project: Semester project (bachelor)
Duration: 14 weeks (Official start/end date: February 17-May 30)
Submission of final report: June 16
Final Presentation: TBD
Recommended: This project is suitable for a student interested in the software design of autonomous observatories and space surveillance and tracking with a background in software engineering. Prior knowledge in Python is a plus.
CONTEXT
eSpace and LASTRO are currently expanding their observation capabilities with TELESTO, a 60 cm telescope located at the observatory of Geneva in Sauverny. To enable remote observations, a new weather station was recently installed at the telescope. This weather station does not only provide the remote observer with critical information on the observing conditions on site but can also initiate emergency procedures to close the dome to protect the equipment in case of dangerous weather conditions. This project is intended to develop a graphical user interface that provides the user with a comprehensive overview of all relevant sensor readings and issues alerts in case the weather conditions require to pause observations.
PROJECT SCOPE
During the project, you will familiarize yourself with the telescope and its hardware and software environment. The weather station is connected to the acquisition PC via serial port and the vendor provides a python package that contains an API to access the sensor readings and configure the station. Your task will be to design and develop a graphical user interface for the weather station using the API provided by the vendor. The interface should display all relevant sensor data in the form of a dashboard, allow configure thresholds for warnings and autonomous dome emergency closure and also issue alerts in case the conditions get critical. These alerts should be implemented in several stages, ranging from acoustic warning to sending an SMS to the remote observer.
TASKS
- Familiarize yourself with the telescope, weather station and the software interfaces
- Develop a graphical user interface in the form of a dashboard that provides the observer with critical information on the weather conditions
- Implement configurable alert procedures to inform the remote observer in case the conditions become dangerous
