CubeSats are small satellites characterized by their cubic shape and standardized dimensions. Typically ranging from 10x10x10 centimeters (1U) up to 30x20x10 centimeters (3U), these miniature satellites are designed for various missions, such as Earth observation, scientific research, and others. Initially developed for educational and demonstration purposes, CubeSats have rapidly gained popularity due to their cost-effectiveness, versatility, and ability to be launched in large numbers. The standardization of CubeSat dimensions has organized their integration into launch vehicles, allowing multiple CubeSats to lift a ride into space alongside larger payloads. Ridesharing, a shared launch approach, has lowered the barriers for organizations and institutions to carry out space missions. As a result, CubeSats have enabled a diverse array of entities, including universities, startups, and even individual researchers, to participate in space exploration and technology development.

Observation, remote sensing, telecommunication, and other services

The applications of CubeSats span a wide range of disciplines, reflecting their versatility and adaptability to various mission objectives. One of the most prominent uses of CubeSats is in Earth observation and remote sensing. Equipped with miniature instruments and sensors, these satellites capture high-resolution imagery and collect valuable data about the planet's environment, climate patterns, and natural disasters. Such data is invaluable for monitoring and managing Earth's resources, predicting weather phenomena, and assessing the impact of human activities on the environment.

CubeSats have also ventured into deep space, conducting scientific investigations, and exploring celestial bodies. These missions often utilize the compact size and modular design of CubeSats to test new technologies and conduct experiments in microgravity environments. For example, CubeSats have been deployed to study asteroids, comets, and other celestial objects, shedding light on the origins of the solar system and the potential for extraterrestrial resource utilization. Arkyd-3R mission, launched in 2015, aimed to demonstrate technology for prospecting asteroid resources, such as water and precious metals, essential for future space exploration and industry.

In addition to scientific research, the CubeSats industry has become an essential part in progressing telecommunications and satellite-based services. Smallsat constellations, composed of multiple CubeSats working in concert, are being deployed to provide global connectivity, facilitate internet access in remote regions, and support disaster response efforts. They are bridging the digital divide and enhancing connectivity on a global scale, through the expansion of access to communication infrastructure.

Further progress in space exploration

Despite their diminutive size, advances in miniaturization, propulsion systems, and onboard computing have enhanced the capabilities and performance of these small satellites. Miniature propulsion systems enable CubeSats to operate in space, adjust their orbits, and even perform complex trajectory changes. Meanwhile, advancements in solar panels and energy storage systems have extended the operational lifespan of CubeSats, enabling longer-duration missions and sustained data collection. For example, ThrustMe, a space technology company based in France, has developed an innovative electric propulsion system called the Iodine Electric Propulsion System (iEPS). This system is specifically designed for small satellites like CubeSats, offering efficient propulsion capabilities that enable precise orbit adjustments, station-keeping maneuvers, and even complex trajectory changes. The use of iodine as a propellant provides higher efficiency and compactness compared to traditional propulsion systems, making it ideal for small satellite missions requiring extended operational lifetimes and maneuverability in space.

Moreover, the integration of AI and ML algorithms is transforming how CubeSats operates and processes information. AI-enabled CubeSats can autonomously analyze data, identify patterns, and make real-time decisions, enhancing the efficiency and responsiveness of space missions. These technological advancements not only expand the scope of what they can achieve but also pave the way for future innovations in space exploration and satellite technology.

Collaborative efforts between public and private sectors influencing innovation

CubeSats has immense potential as ongoing advancements in technology and infrastructure continue to expand their capabilities. In the coming years, CubeSats are expected to play an important role in space exploration initiatives, including lunar exploration, Mars missions, and beyond. Collaborative efforts between public and private sectors are influencing innovation in CubeSat technology, strengthening new partnerships and opportunities for international cooperation in space. Moreover, the commercialization of space is creating newreducing costs but also accelerating the pace of innovation in the aerospace industry, positioning CubeSats as key enablers of future space missions and scientific discoveries.
