Researchers have discovered an unknown material on Mars. The material could provide clues that there may have been life on Mars in the past.
An unknown mineral has been recently discovered on Mars: Researchers refer to the material as an iron hydroxysulfate.
The discovery is currently making waves worldwide because it could indicate dynamic geological processes and possible past living conditions.
Iron hydroxysulfate has only been found on Mars so far
Who has conducted research there? An international research group led by Dr. Janice Bishop, a scientist at the SETI Institute and NASA Ames Research Center (ARC), has identified and characterized an unusual iron hydroxysulfate material through a combination of laboratory experiments and observations from Mars orbit. You can view the complete research results directly on Nature.com.
What was actually found? It is an iron hydroxysulfate that differs from previously known minerals by its unique crystal structure and high thermal stability.
It is believed to have formed through the combination of heat and oxygen, which is remarkable for Mars and indicates geothermal activity as well as dynamic chemical processes in more recent geological times. This has been reported, among others, by the magazine Ingenieur.de.
So far, the material has not been brought to Earth and has only been replicated in laboratories on Earth. The material was exclusively collected by a special rover on Mars. Therefore, it has not yet been officially classified as a mineral since it could not be directly examined here.
New mineral is expected to provide clues about past life on Mars
What does this discovery mean? The mineral is a significant indication of heat sources and possibly favorable conditions for microbial life in the past of the red planet.
The discovery of the mineral on Mars provides new clues about how the planet’s surface and climate have changed over time. Iron hydroxysulfate typically forms when iron minerals react with water and sulfur-containing substances.
This means that where the mineral was found, there was once water and an environment with certain chemical properties. Possibly even favorable conditions for microbial life. Thus, researchers believe that this find must also be a sign that there may have once been life on Mars.
With each new day, humanity learns a little more about outer space. Perhaps it will even one day be possible (and necessary) to resettle part of humanity on Mars. NASA is currently gaining new insights through an experiment on what life on the red planet might look like: NASA has locked 4 people in for a year to simulate life on Mars – They were asked what they did with their time
