Scientists have finally created the spider-like formations found on the surface of Mars.
You're on the list! Expect to receive your first email very soon!The Planetary Science JournalDuring the published experiments, scientists replicated the process they thought was happening and managed to recreate these “spiders.”
While many such spiders were observed, no one was quite sure how they were formed, though they hypothesized the process involvedIn the new study, scientists wanted to confirm their theory and mimic conditions similar to the temperatures and air pressure of Mars in a specialized laboratory chamber.The experiment was based off a model created three years ago, which detailed a potential way these “spiders” were formed, has been working on this project for five years.
During Martian spring, sunlight would shine through slabs of CO2 on the surface, which heated the ground. In turn, this caused the ice to sublimate into gas and create pressure buildup within the ice slabs.The ice cracked once the pressure got too high and enabled the gas to escape. As the gas seeped out of the cracks, it brought a stream of dark dust and sand from the surface, leaving behind the spider-like formations when the ice melted during the summer.
Geologists have studied rocks, sediments, and soil for clues on the history of the surface — specifically through volcanoes, craters from meteorite impacts, atmospheric or photochemical effects, and other geophysical processes.
