Special Issue "Green Propulsion: Present Solutions and Perspectives for Powering Environmentally Friendly Space Missions"
Deadline for manuscript submissions: 31 December 2021.
Interests: composite solid propellants, liquid storable propellants; metal fuels; green propulsion, launch systems
Humankind has largely benefitted from space activities and related technologies. The outcomes of those activities and technologies are currently an essential part of our daily lives, granting us services, safety, rapid emergency response, and scientific improvements. Space industry is substantially growing thanks to new private actors entering the market and leading to cost reduction for launch services and space platform development. This trend, deemed to rise further due to the commercial exploitation of Earth orbits, brings several concerns about the effective environmental sustainability of the space sector. Thermochemical propulsion is considered one of the factors for improvement.
The environmental impact of space propulsion includes short- and long-term effects on humans and on the environment. These are caused by propellant production, handling, storage, use, and disposal, during both normal operating conditions (e.g., exhaust products, tank venting) and emergency situations (i.e., catastrophic launch failure and consequent on-ground propellant contamination).
There is not a rigid definition of “green propulsion,” so under this classification a wide range of research and development activities are gathered. Space agencies and institutions are supporting specific initiatives, development plans, and solutions aiming at improving the sustainability of the space sector in both short and long-term perspectives, in compliance with the UN Sustainable Development Goals. NASA’s “Green Propulsion Technology Development Roadmap” and ESA’s “CleanSpace” initiatives represent only two examples of this global cooperative R&D effort in which agencies, industries, and the academy are active actors.
This Special Issue aims to collect contributions in the area of the thermochemical propulsion for launchers and spacecraft operations, focusing on the assessment and on the reduction of the environmental impact deriving from propulsion systems. Potential topics include, but are not limited to:
- Impact evaluation of current propellants and related propulsion technology solutions on environment and involved workers
- Literature surveys, trade-off analyses, and evaluation studies on green propulsion solutions for spacecraft and launchers
- Experimental/numerical/theoretical activities related to green propulsion developments
- Solid, liquid (storable, cryogenic), hybrid thermochemical propulsion systems aiming at improving the sustainability of current and future space industry
- Peculiarities and relevant aspects characterizing the combustion processes of propellants for green propulsion systems
- Issues and improvements related to propellant lifecycle (production, handling, storage, disposal, and emergency management)
- Evaluation of short- and long-term effects of combustion products on environment and humans (e.g. plume, acid rains, groundwater pollution, toxicological effects, etc.)
- Status advancement/final conclusions of projects, or part of them, concerning green propulsion topics.
