The Aether: T-ReX (Thermal Re-entry eXperiment) mission is an educational and technological initiative developed by Aetherspace, a student team connected to the Technovation postgraduate program at KU Leuven in Belgium. The mission's goal is to make space research more accessible by developing a low-cost re-entry CubeSat platform capable of returning scientific payloads and experimental samples back to Earth.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

Today, returning material from space is a complex and expensive process, often dependent on missions to the International Space Station. With Aether: T-ReX, the team aims to demonstrate a new pathway: using the CubeSat standard as a compact and affordable platform for re-entry missions. The current mission is the first iteration of this concept \u2013 a 3U CubeSat-based demonstrator designed to survive suborbital flight and atmospheric re-entry after being launched aboard a REXUS sounding rocket.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

The Aetherspace team currently consists of 8 full-time student members, more than 10 part-time contributors, 2 PhD researchers, 2 coaches, and a growing network of alumni. Beyond engineering, the project also focuses heavily on education, outreach, and interdisciplinary innovation by combining aerospace engineering, embedded electronics, software development, systems engineering, and project management within a student-driven environment.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

The team has been supported throughout the development process by Eurocircuits<\/a>, whose PCB manufacturing services are used across nearly every subsystem of the mission \u2014 from power electronics and communication systems to RF boards and camera interfaces. As the project enters its integration and testing phase, reliable PCB production has become increasingly critical for ensuring mission success under the extreme environmental conditions of launch and re-entry.<\/p>\n\n\n\n

The Aether: T-ReX mission consists of two major elements: a Rocket Mounted Unit (RMU) that remains attached to the rocket and a Free Falling Unit (FFU), which acts as the actual re-entry CubeSat demonstrator.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

During the mission, the REXUS rocket will carry the experiment to an altitude of approximately 80-90 km. At a predefined point in the flight timeline, the RMU deploys the FFU from the rocket nose cone using a custom deployment system inspired by CubeSat P-Pod mechanisms. After ejection, the FFU begins an autonomous free-fall trajectory back toward Earth.<\/p>\n\n\n\n

One of the mission's most important technological demonstrations is the inflatable heat shield system. Shortly after deployment, a dedicated Inflation System activates cool gas generators that inflate a torus structure around the vehicle. This structure deploys and stabilizes the heat shield, which protects the CubeSat during atmospheric descent.<\/p>\n\n\n\n

The mission is designed to gather extensive flight data during all phases of the trajectory. The team measures:<\/p>\n\n\n\n
