Preparation process for the firing

Could you walk us through the main objectives and outcomes of missions like MYSat-1, DhabiSat, MeznSat, and Light-1?

Since 2016, Khalifa University has worked on and launched four CubeSats, each with its own purpose:

  • MYSat-1 (1U, 2018) – Built to test a small camera and an experimental lithium-ion battery that we developed in-house.
  • MeznSat (3U, 2020) – Used to measure greenhouse gas concentrations above the UAE, helping provide useful data for climate and environmental research.
  • DhabiSat (2U, 2021) – Focused on testing our own attitude determination and control algorithms in orbit.
  • Light-1 (3U, 2021) – A joint mission with NYU Abu Dhabi and Bahrain’s National Space Science Agency, carrying a payload from NYUAD to detect gamma-ray flashes caused by thunderstorms.

These missions gave us valuable technical experience and taught our students and researchers what it takes to design, build, launch, and operate satellites. What we learned from them directly feeds into our current and future projects.

How do students participate in end-to-end satellite development – from design to launch and operations?

At KUSTIL, students are immersed in the full satellite development lifecycle through a unique blend of academic coursework, practical training, and direct involvement in real space missions. From the earliest design phases, students work alongside faculty, researchers, and industry partners to define mission objectives, design subsystems, and perform simulations.

They then move into integration and assembly, working hands-on in the university’s space labs to build and integrate components such as structure, ADCS, propulsion, and power systems. This is followed by environmental testing in the dedicated test laboratory, where students gain experience with thermal-vacuum, vibration, and other qualification tests in compliance with space industry standards.

When the satellite is ready for launch, students participate in pre-launch preparations, interface with launch providers, and, after deployment, engage in mission operations including tracking, telemetry analysis, and payload data handling. 

This end-to-end exposure ensures that graduates leave with both theoretical knowledge and real-world experience, fully prepared for roles in the UAE’s growing space sector.

What technical lessons have you learned from operating CubeSats in orbit, and how have they informed future missions?

A key lessons-learned is that there is no substitute for thorough testing. The more we test subsystems and payloads under realistic conditions, the more reliable the mission becomes. These experiences have reinforced the need to strengthen our testing and validation processes for future CubeSat projects.

What motivated the development of the eco-friendly micro-propulsion system for a 6U CubeSat, and what challenges did your team face?

Recent United Nations Office for Outer Space Affairs (UNOOSA) assemblies have highlighted the growing congestion in Low Earth Orbit (LEO) and the associated risks to long-term space sustainability. As a result, new regulatory measures are being proposed one of the most significant being the mandatory inclusion of propulsion systems for all mission types, regardless of size or scope.  For KUSTIL, this reinforces the strategic importance of investing in propulsion system development. 

Also, satellite constellations, in particular, demand intensive station-keeping capabilities to maintain precise orbital positions, making propulsion an essential subsystem for more complex missions and multi-satellite networks. Our decision to focus on green propellants is driven by two key factors:

Sustainability: Green propellants minimize environmental impact and support the long-term viability of space operations.

Accessibility & Reduced Complexity:  Unlike traditional toxic propellants, green propellants simplify handling and integration processes, lowering safety requirements and making the technology more accessible to a wider range of developers and mission planners.

Through this approach, KUSTIL aims not only to meet emerging regulatory requirements but also to contribute to the responsible and sustainable use of space.

How does your hydrogen peroxide propulsion compare to traditional chemical systems in performance and safety?

The initial test results of our HTP (High-Test Peroxide) propulsion system are highly encouraging, demonstrating only a minimal performance gap compared to existing hydrazine-based systems. This performance difference can be effectively narrowed through ongoing optimization of catalyst formulations and careful selection of advanced materials, areas in which KUSTIL is actively investing. From a handling and safety perspective, HTP offers significant advantages over toxic propellants like hydrazine. Its benign nature reduces operational hazards, simplifies ground procedures, and greatly lowers the complexity and cost of developing test facilities. Moreover, the use of HTP facilitates the selection of compatible components, as stringent toxic-propellant handling requirements are not necessary.Overall, HTP is an optimal choice for developing high-performance, safe, cost-effective propulsion for small satellites, supporting mission efficiency and sustainable space operations.

What other innovations are being pursued at the KUSTIL such as AI in space, robotics, or advanced sensors?

At KUSTIL, we are pursuing a diverse range of innovations to support the next generation of space missions. This includes the development of sustainable and eco-friendly materials, such as graphene-infused wood, for future space structures, as well as research into advanced mobility systems for the Moon and Mars that move beyond traditional wheeled rovers. Another key area of focus is the advancement of Attitude Determination and Control Systems (ADCS), one of the most complex and mission-critical subsystems for satellites. We are actively developing high-precision components such as reaction wheels and star trackers, while also integrating artificial intelligence into ADCS algorithms to improve performance, autonomy, and fault tolerance. AI and edge computing more broadly are also central to our research, enabling smarter data processing and communication both between satellites and from space to ground.

How does Khalifa University integrate space missions into its curriculum?

A hands-on space systems engineering course based on CubeSat development has been introduced as a core course for senior undergraduates, giving students practical exposure to real mission design. This unique approach in the region ensures graduates gain both theoretical knowledge and direct project experience, preparing them for immediate contribution to the space sector.
