GloDEX – an experiment for the detection of global 21-cm line

Stepping stones toward our ALO observatory: As we refine concepts, develop instrumentation and engage with industry and academic partners to advance the technologies and collaborations, we are developing scientific capabilities essential to future lunar astronomy.

The far side of the Moon offers an exceptionally quiet radio environment, making it an ideal setting for detecting the extremely weak global neutral hydrogen signal from the early Universe. Our GloDEX concept is designed to fully leverage these unique conditions. By placing several widely separated antennas on the lunar surface, we can validate measurements across stations and distinguish genuine cosmological signals from instrumental effects. Capturing this signal will allow us to explore the emergence of the first stars and galaxies and deepen our understanding of how the Universe evolved over time.

Embassy of the Moon

As humanity prepares to return to the Moon and expand scientific activity across cislunar space, the importance of responsible, sustainable and inclusive space exploration has never been greater. The ALO team is committed not only to advancing transformative lunar‑based radio astronomy but also to ensuring that this scientific progress aligns with societal values, the long‑term stewardship of the lunar environment, and the ethical use of space.

ALO team coordinator, Marc Klein Wolt, has co‑initiated the “Embassy of the Moon” community, a public‑facing initiative creates a platform for artists, scientists, policymakers, and the broader public to reflect on the meaning of the Moon in society, its cultural significance, its scientific potential, and the responsibilities that come with setting foot permanently on another celestial body. 

The first session was organised in collaboration with Tylers Museum, here is a short preview of the event: https://teylersmuseum.nl/nl/ambassade-van-de-maan

Stay tuned for more updates as ALO continues to advance both the scientific and societal dimensions of lunar exploration.
