Key Market Challenges

Increasing Space Debris and Collision Risks

One of the most urgent issues in the Global Satellite Propulsion System Market is the increasing problem of space debris and the resultant risks of satellite collisions. With an increasing number of satellites being launched into space, especially in mega-constellations, the risk of collisions and the spread of space debris increases. This issue is driven by a mix of factors, such as non-functional or obsolete satellites, rocket stages, and mission fragments. Space junk is a major hazard to functional satellites in orbit. It may result in catastrophic damage, even mission failure, or the creation of even more pieces of debris, further accelerating the issue. Propulsion systems play a critical role in de-escalating these collision hazards through collision avoidance maneuvers, orbitals readsjustments, and strategies for avoiding debris.

It is difficult to detect and track space debris because there are many objects in orbit, of different sizes, and irregular shapes. It is difficult to predict possible collisions and take corrective action in time using sophisticated tracking technology and coordination between satellite operators. Propulsion systems need to be able to perform quick and accurate collision avoidance maneuvers. This not only needs efficient propulsion but also advanced algorithms and real-time monitoring systems to evaluate collision threats. Satellites require propulsion systems for controlled deorbiting at the end of their missions so that they re-enter Earth's atmosphere and burn up, instead of becoming part of the space debris.

The prevention of space debris and collision threats is a vital issue on which space agencies, regulatory authorities, and satellite operators are currently working. Formulation and enforcement of adequate guidelines for the management of space debris and enhancement of space traffic management are essential aspects towards tackling this issue.

The sustainability of space operations has become a significant focus, encompassing aspects such as orbital congestion, debris mitigation, frequency coordination, and responsible space practices. Satellite operators need to incorporate propulsion systems that support space sustainability objectives, including deorbiting defunct satellites and preventing on-orbit collisions. The allocation and management of radiofrequency spectrum for satellite communications is another challenge. Satellite operators must navigate complex regulatory processes to secure the necessary spectrum, ensuring that their satellite systems can operate without interference from other satellite systems or terrestrial communications. Complying with these evolving regulatory requirements and ensuring the sustainability of space activities is critical for long-term market growth and stability. Regulatory challenges may also extend to export control restrictions, as some propulsion technologies are subject to export controls to prevent their misuse in dual-use applications.

Key Market Trends

Transition to Electric Propulsion Systems
One of the most significant trends in the Satellite Propulsion System Market is the growing adoption of electric propulsion systems. Electric propulsion, such as ion thrusters and Hall-effect thrusters, is becoming increasingly popular because it is efficient, enabling satellites to gain considerable fuel savings and increase their operational lifespans. The trend is fueled by the necessity to lower launch costs and prolong satellite mission lengths. Electric propulsion systems operate by ionizing a propellant, such as xenon or krypton, and then accelerating the ions at high velocities to produce thrust. They have a much greater specific impulse (Isp) than conventional chemical propulsion, which translates into being able to achieve the same change in velocity (delta-v) with much less propellant. The benefits of electric propulsion are longer mission times, more effective orbit raising, higher payload capacity, and higher flexibility in orbit maneuvers. These systems are especially useful for geostationary satellites, interplanetary missions, and spacecraft in medium Earth orbit (MEO). Airbus, Northrop Grumman, and Maxar are integrating electric propulsion systems into their satellite designs. Electric propulsion is particularly vital for satellite constellations, including those for Earth observation, global broadband internet, and space exploration missions. With more organizations appreciating the advantages of electric propulsion, the technology is now a leading trend in the industry.

As there is an increasing concern over space debris and the environmental effect of satellite propulsion, there is an increased focus on creating sustainable and environmentally friendly propulsion systems. This is because the risks involved in using conventional chemical propulsion systems are to be mitigated. Conventional chemical propulsion systems based on hydrazine or other toxic and carcinogenic propellants have the capability of creating space debris by propellant explosions or release of spent rocket stages. Green propulsion attempts to reduce these environmental hazards. Water-based propulsion is one of the prime examples of green propulsion. It consists of using water as a propellant, which is non-toxic, non-hazardous, and available in abundance. Water-based propulsion is a green alternative to conventional chemical propulsion and is particularly suitable for small satellites and CubeSats, which are being deployed more frequently for Earth observation, scientific experiments, and technology demonstrations. Electric propulsion technologies like ion thrusters are also green propulsion technologies based on their high efficiency and low propellant mass utilization. Because they are based on noble gases such as xenon or krypton, they are not toxic exhaust products, which makes them a cleaner and greener choice for satellite propulsion. The use of green propulsion technologies is part of the space industry's increasing focus on responsible space operations and environmental stewardship. Regulatory authorities such as the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) are further highlighting the necessity of preventing space debris and keeping space activities free from any detrimental environmental impact.

The necessity for satellite servicing arises due to the rising number of old satellites in space, the need to optimize returns from satellite investments, and the possibility of minimizing space debris. The Satellite Propulsion System is key to in-orbit servicing missions, enabling precise maneuvers, rendezvous, docking, and proximity operations. Propulsion systems provide means for servicing satellites to maneuver to their target satellites, connect, and support multiple servicing activities. Northrop Grumman, with its Mission Extension Vehicle (MEV), and Astroscale, with its End-of-Life Services by Astroscale (ELSA) missions, are leaders in in-orbit satellite servicing. These missions demand advanced propulsion systems to reach and dock with customer satellites, handle proximity operations, and make orbital maneuvers. In-orbit servicing offers several benefits, such as the prolongation of satellite life, the capability to adjust to evolving mission requirements, and the possibility of removing dead or non-functional satellites from orbit to decrease space debris. This is fueled by the growing awareness of the economic and environmental advantages of maintaining satellites over replacing them with brand new ones. As satellite operators try to get the most out of their investments and mitigate sustainability issues, in-orbit servicing will continue to gain more prominence in the market.
