Space debris are of growing concern to the global space community. One way to reduce the increase in the number of space debris added each year is by prolonging the on-orbit lifetime of the satellites either by performing on-orbit refueling or with the help of a service satellite. Most of the current solutions depend on information regarding the status of the target satellite or the debris. The target satellite could have been changed due to the effects of space weather, mechanical abrasion, malfunction and damage (especially in case of debris removal). Getting precise data on the actual state of the debris is therefore a primordial element in any mitigation strategy.
Especially in geostationary orbit, given the communication delay, a geostationary docking requires a sophisticated control system to dock with the target satellite autonomously without real-time ground assistance.

A solution for such application might come from the depths of the oceans: COMEX develops sophisticated underwater vision and photogrammetry systems that could be used in the space sector. ORUS3D by COMEX SA is the only underwater 3D photogrammetry solution certified for subsea metrology by Bureau Veritas that can create 3D models of underwater infrastructure with submillimetric resolution. The system can be used in various applications, ranging from precise cartography of archeological sites on the seabed, caves or autonomous classification of objects by underwater robots (ROV or AUV).

The system is proposed to produce high resolution and precision models of a satellite in orbit with the help of computer vision and photogrammetry . From a set of images that are seeing the same scene with various angles, CX3d will compute a model that is made of the scene interest points 3D coordinates and the position of the image.

The system has been tested for the space sector in different set-ups at the COMEX facilities in Marseille, France: COMEX performed underwater trials with a mock-up satellite to verify if neutral-buoyancy simulations of such a system could be feasible (e.g. simulating manipulations of a target satellite by a service satellite underwater in simulated weightlessness).
Also tests in dry conditions were performed with the system to verify if it could be implemented on existing space simulators.

PROJECT TRAILER: TANDEM OF TWO ROVERS
FOR EXTENDING LUNAR EXPLORATION

PRESS RELEASE

TRAILER system exploring lunar tubes (image: LIQUIFER)

31 October 2019 The European Space Agency (ESA) signed a contract on the development of the “TRAILER” robotic system with COMEX and its partners The German Research Center for Artificial Intelligence Robotics Innovation Center (DFKI RIC) and LIQUIFER Systems Group. TRAILER is a two-year project to test a novel architecture of robotic cooperation based on a tandem of two rovers for lunar surface exploration missions.

ESA is working with its international partners on the development of the lunar GATEWAY, the first permanent human outpost beyond Earth’s orbit. GATEWAY must be considered as a Base Camp that will serve to set-up missions on the surface of the Moon as part of the HERACLES and ARTEMIS Program. Astronauts and robots will work together to prepare the coming era of space exploration with missions to the lunar South Pole and other locations: robotic explorers will search for ISRU elements that could support a human presence on the surface. These scouts will be operated either from Earth or from GATEWAY in lunar orbit; and they will need to perform certain tasks in autonomy. The main objective of the TRAILER activity is to develop a rover system consisting of 


    • An agile and powerful rover (TRACTOR) equipped with high performance locomotion and navigation, local wireless transceiver, short-term energy storage, sample acquisition system, and
    • An active trailer (WAIN) equipped with limited locomotion and navigation, high power generation or storage and local wireless network that could assure lunar-earth communication and host a scientific laboratory for sample collection and analysis.

System components of the TRAILER project (image: COMEX)

The TRAILER activity is led by the Marseille-based company COMEX that develops the “WAIN”, a heavy lunar robotic vehicle that carries the communication, batteries and sample containers. DFKI RIC in Germany is responsible for simulations and development of the second robot, the “TRACTOR”, an agile scout robot that brings the samples back to WAIN. LIQUIFER Systems Group in Austria defines the mission scenarios of the robotic tandem and planning. The TRAILER system will be tested in test facilities at the partner organizations in France, Germany and Austria.

EUROPEAN SPACE AGENCY ASSIGNS COMEX TO SUPPORT THE UNDERWATER TRAINING OF ASTRONAUTS IN COLOGNE

PRESS RELEASE

EUROPEAN SPACE AGENCY ASSIGNS COMEX TO SUPPORT THE UNDERWATER TRAINING OF ASTRONAUTS IN COLOGNE

COMEX and the European Space Agency (ESA) have signed a contract on astronaut underwater training at the European Astronaut Centre (EAC) in Cologne.

On May 18th, 2019, the Marseille-based enterprise COMEX (Compagnie Maritime d’Expertises) and the European Space Agency (ESA) have signed a contract on supporting the underwater training of astronauts and operations of ESA’s Neutral Buoyancy Facility (NBF) at the European Astronaut Centre in Cologne. The NBF is a unique training and testing facility housing a 10 m deep water tank, in which full scale mock-ups of International Space Station (ISS) modules are immerged. This is the only place in Europe, where astronauts receive training for Extra-Vehicular Activities (EVA) also known as spacewalks. ESA has developed and implemented in the NBF a world-wide unique EVA Prefamiliarisation Training Programme to train the European astronauts on the rules of engagement for spacewalks on the International Space Station (ISS). This programme has proven its efficiency with the multiple spacewalk assignments of ESA astronauts in the past 10 years and is also used as EVA proficiency training in Europe. “This innovative ESA training has been in place for already 15 years and is regularly enhanced through a very fruitful cooperation with NASA. Its objective is to boost ESA astronaut initial EVA capabilities in safely and efficiently performing EVA tasks, before they get exposed to the spacesuit constraints through their further EVA skill training by NASA in Houston. Having now COMEX on board is an additional and appreciated asset for the diving activities in the NBF” says Hervé Stevenin, ESA Head of the EVA training at EAC.

The NBF also offers the capability to simulate the Moon gravity through immersions in slightly negative buoyancy. ESA has already prototyped Lunar EVA equipment & tools, which have been tested in simulated lunar gravity inside the NBF tank for the preparation of the ESA upcoming contribution to the return of humans to the Moon surface.

The present contract also includes the continuation of these activities to test European lunar surface operations and hardware to prepare the return of astronauts on the Moon. “Within this contract we will provide ESA with a team of divers to support the training of astronauts underwater for missions to the International Space Station (ISS). But the project goes beyond ISS and will also serve to support ESA contribution to future human lunar exploration missions” says Peter Weiss, Head of the Space Department at COMEX. The company is working for ESA on several projects related to the future Moon exploration and is actively investigating spin-off technologies and synergies between the maritime and space sectors.

Kathrin Nowak, NBF Diver and COMEX Team Lead at the European Astronaut Centre says: “Most of the divers working for COMEX in Cologne have a long experience of supporting astronaut training and tests at the Neutral Buoyancy Facility. We are happy that we can combine the expertise of COMEX and the proficiency of the diving team to support ESA in NBF activities”.

About COMEX The Compagnie Maritime d’Expertises (COMEX) was founded in 1961 by Henri Germain Delauze (1929-2012). It is a worldwide pioneer in offshore diving and technologies for human interventions in extreme environments. The Compagnie is involved in several projects for the European Space Agency on the development of technologies to return humans to the Moon such as the development of materials of future space suits (Project PEXTEX) or the design of the Science Airlock for the future space station GATEWAY (Project ESPRIT under a contract with AIRBUS).

New intelligent materials for future space suits

New intelligent materials for future space suits

New intelligent materials for future space suits

All space agencies are preparing for a return of man to the moon in the relatively near future!
It is in this context that the European Space Agency (ESA) is launching the “PEXTEX” project.
The aim of the project is to identify future space combinations of new materials and intelligent textiles.
Signed on January 17, 2019, the two-year study was entrusted to the Space Department of Comex.sa, as coordinator, and to its European partners the German DITF and the Austrian OeWF.

The project aims to find, in addition to existing materials on space suits, new components to incorporate additional features. To guard against dangers, but also to analyze the environment, to monitor the health of astronauts, etc. The possibilities are numerous. For example, there are rains of micrometeorites on the lunar surface; the search for textiles capable of maintaining their structural integrity is a first-rate challenge, knowing the disastrous consequences that a combination tear could cause!
For this purpose, and in order to be better adapted to this environment, the study will allow the identification of intelligent materials such as innovative polymers such as shape-memory textiles, but also e-textiles in which electronic components would be inserted. and computer, the interest is to have materials capable of capturing, analyzing and reacting autonomously and safely.
The materials that will be identified as part of the PEXTEX project will be tested in test facilities with partner organizations in France, Germany and Austria.

Fifty years after the Apollo missions, human space exploration is at the dawn of a new era, ESA and its international partners are working to return man to the moon. Establishing a permanent presence on the lunar surface is the role of future missions. The identification and testing of such materials could be used for the development of future European space suits for extravehicular activities (EVA) on the lunar floor and these space suits should be designed to withstand longer and more frequent surface operations than during the Apollo period.

This project is part of ESA’s exploration strategy to return to the moon in the coming decades. Just like the development of GATEWAY, the future space station in lunar orbit. This station will serve as a “base camp” to perform robotic and human missions on the lunar surface. Project in which Comex.sa is also associated, in partnership with Airbus, for the development of one of the “ESPRIT” modules..

Under the direction of Dr. Peter Weiss and his close collaborators Thibaud Gobert and Makthoum Peer, the Space Department is increasingly involved in this great adventure of space conquest and especially lunar exploration, congratulations to them.

COMEX joins AIRBUS in the development of ESPRIT the European Module of the lunar orbital space station GATEWAY

October 24th 2018, COMEX and AIRBUS signed a cooperation agreement to develop ESPRIT, one of the European modules of the GATEWAY, the future lunar space station.

The GATEWAY is the first step of human space exploration after the era of the International Space Station. It will be a basis for missions to the lunar surface by robotic vehicles and astronauts. Its assembly in lunar orbit is scheduled to start in 2023.

The GATEWAY is a planned lunar-orbit space station that will have a power and propulsion system, utilization and crew habitation modules with docking capability, scientific and extra-vehicular activity airlocks, and logistics modules. The development is led by the current International Space Station partnership: NASA, ESA, ROSCOSMOS, JAXA and CSA, for launch to the Moon in the 2020s.

AIRBUS is leading as prime one of the two parallel Phase A/B1 studies for the development of the ESPRIT module (European System Providing Refueling, Infrastructure and Telecommunications), in cooperation with COMEX S.A., Marseille and other European Partners. ESPRIT is a system, planned to be launched with the first Utilization Module (an US supplied pressurized module). It includes propellant (Xenon and Hydrazine) storage and refueling systems for the Power Propulsion Element (the first US element of the Gateway), communication systems with the Lunar base, interface points for external payloads and a scientific airlock.

COMEX joins AIRBUS in the development of this space module, by bringing in its engineering expertise and testing capabilities. The Marseille based company was a pioneer in the development of subsea systems and professional diving. Since 2012, COMEX has been actively involved in human space flight activity and stratospheric platforms.

Waste is a resource! even on the moon

January 8, 2018. The European Space Agency (ESA) entrusted the URBAN Consortium, which includes COMEX in Marseille, LIQUIFER Systems Group and SONACA Space GmbH, under the direction of OHB System AG, the study “Designing a lunar base using 3D printing technologies”. The team will evaluate the feasibility and implementation of additive layer manufacturing in the construction, operation and maintenance of a lunar base.

Logistics and bringing needed items into space or onto a planetary surface remains as one of the major constraints in long-term human space missions. Experts across the space sector have shown great interest in the utilization of lunar resources as the next logical step in implementing a global strategy for human exploration of the solar system.

Therefore, the key to any sustainable presence in space is the ability to manufacture the necessary structures, items and spare parts, on-site and on-demand. This can reduce the cost and volume of cargo missions launched from Earth, if a substantial portion of the elements needed for long-duration missions can be produced locally. Additive manufacturing technologies represent a potential solution to this goal, as they can reduce lead times from design to implementation and reduce manufacturing waste, while increasing recyclability and the ability to produce optimized parts. on demand.

The URBAN study will examine the capacity of these additive manufacturing techniques by carrying out two parallel surveys. The first concerns the mapping of the material required for a permanent human lunar base. The other survey is an analysis of available additive layer manufacturing technologies and their potential capabilities in a lunar environment. The assessment includes the state of the art 3D printing related to many materials such as metals, polymers, ceramics, concrete, food ingredients, living tissue and even … waste.
