An unusual message from Mars, transmitted as part of an experimental project, has intrigued citizen scientists worldwide for months. The European Space Agency (ESA) and the SETI Institute sent this signal to simulate a real extraterrestrial transmission and assess how humanity might decode such messages. After intense analysis and teamwork, the coded signal has now been cracked by a father-daughter duo in an impressive feat of collaboration.

The Mysterious Signal and Its Purpose
In May 2023, ESA’s ExoMars Trace Gas Orbiter beamed an encoded signal to Earth as part of a project led by artist Daniela de Paulis, the SETI Institute’s Artist in Residence. Named “A Sign in Space,” this project aimed to simulate a scenario in which Earth receives a message from extraterrestrial intelligence, testing our ability to interpret it. In partnership with thousands of volunteers, scientists and amateur enthusiasts embarked on the challenge of analyzing this Mars signal. The exercise drew widespread interest, creating a unique moment of global collaboration around a shared curiosity.
Decoding Efforts Led by a Determined Father-Daughter Pair
After over a year of work, father Ken and daughter Keli Chaffin finally succeeded in decoding the Mars message. Using a combination of simulations and intuition, they identified the hidden information within the signal. Their progress accelerated in the first ten days, thanks to the assistance of 5,000 volunteers who helped extract data from the raw radio transmissions. However, the toughest challenge lay in deciphering the encrypted code—a process requiring creativity and patience.
Clues of Movement and Life Emerge
Through their analysis, the Chaffins discovered that the signal included elements suggesting “movement,” which could imply processes associated with cell formation or even life. However, the precise meaning remains elusive, leaving much open to interpretation. As ESA noted, decoding a signal is only the first step; understanding its significance is a far more complex task. This experience has highlighted just how challenging it would be to interpret an actual alien message.
Preparing Humanity for the Unknown Through Collaboration
Project lead Daniela de Paulis emphasized that receiving a genuine message from another world would profoundly impact humanity. “A Sign in Space” has provided a valuable opportunity to practice decoding and interpreting potential extraterrestrial signals through an unprecedented level of global cooperation. The experiment shows the importance of interdisciplinary approaches for deciphering such messages and underscores the potential for future scientific advancements.
This success demonstrates the strength of public and scientific collaboration. Decoding a potential alien signal could inspire people worldwide and pave the way for further exploration and knowledge.
