Mars Express has identified a vast river delta that was once no different from existing river deltas on Earth and possibly filled with alien fossils. Mars Express, a Mars survey for the European Space Agency (ESA), has sent back to Earth high-resolution images of the Holden Basin, where billions of years ago there may have been swarms of alien creatures residing on the banks or beneath meandering rivers.
According to Sci-News, the Holden Basin is part of an 8,000-km-long river system with many valleys and depressions, which once helped transport water from the southern region of Argyre Planitia on Mars to the lower region of Chryse Planitia in the south. north.
The complex history of this intricate river system makes it an interesting target for tracing traces of ancient aliens, according to the Mars Express operations team.
A few billion years ago, the impact that created the giant Holden impact crater also created this flow system, called Uzboi-Ladon-Morava, which moved crisscrossing a portion of the Martian surface, gradually forming a complex terrain that includes the Uzboi Valley and Holden Basin.
The water from this system eventually drains northwards through the Morava Valles region. The famous Martian river Ares Vallis, where the first mobile robot Sojorner landed 25 years ago, may also be part of this flow system.
Now, detailed images showing topography and other geological data have led scientists to identify the Holden Basin, which is covered with sediments containing phyllosilicates, as one of the most worthy of study in the entire river system.
Phyllosilicate is a common mineral on Earth, often found in clay. It serves as a reaction center for organic molecules, the factory that creates living organisms on Earth.
ESA scientists will send more instruments to target this area in the future, hoping to find tangible evidence of creatures that existed on Mars several billion years ago.
