MOre three billion years ago, Mars was home to vast oceans, and a new study suggests that this world may seem familiar at once – especially to the inhabitants of Iceland.
Curiosity Rover has been searching for a Gayle crater on Mars since 2012. A careful examination of the geology of the Gael crater reveals what resembles modern Iceland in that region.
Curiosity Has been investigating Maidstone for more than eight years. However, that analysis cannot reveal the conditions above the sample where sediment was produced.
“On ancient rivers and streams, Mars physically and chemically alters the surface, then transports and deposits sediment, resulting in the production of sedimentary rock in downstream valleys, as we see in the remnants of the Gayle Crater, “The researchers described in a published paper JGR Planet.
Stroll around Gayle until you feel at home…
To solve this issue, researchers at Rice University decided to examine the data Curiosity, Compare the geological features found in various places here with us home Ruler, Including Iceland, Idaho, Hawaii, and Antarctica.
“Earth provided an excellent laboratory for us in this study, where we can use multiple locations to see the effects of different climatic variables, and the average annual temperature had the strongest impact for the types of rocks in the Gayle Crater. . The range of climate on Earth allowed us to test our thermometer to measure temperature on ancient Mars Kirsten SiebachA member of the curiosity team that will control curiosity on the Martian surface.
Conditions in Iceland are characterized by high concentrations of basalt, and temperatures averaged only three degrees Celsius (38 F) that were found to be the closest modern equivalent to ancient. Climate of Mars.
Gail craters are once known to contain water. But, planetary scientists have questioned whether Mars water Was largely liquid, or found mainly in the form of ice and snow.
“The sedimentary rocks in the Gale crater extend the climate between these two landscapes. The ancient climate was less likely, but also appears to support liquid water in the lakes for extended periods of time,” Rice University K Michael Thorpe explains.
Temperatures were considered to be the most important condition for influencing the weather of sedimentary rocks formed within streams. And, the weathering effects were extremely mild Rock of mars. In some ways, these three billion-year-old rocks were found today along a specific stream in Iceland.
Typically, geologists examining sludge within rocks would expect to see more soluble deposits from soil (compared to rock) quickly due to the smaller average particle size within the sludge.
However, this study found little loss of these minerals within the mud deposits, suggesting that they were formed at significantly lower temperatures.
The team was also able to give clues together about climate change on Mars, showing that the red planet had climatic periods that were similar to conditions similar to those seen in the Antarctic.
The techniques used in this study can also help us understand the geology of the Jagero crater after the advent of the Persistence Rover ( First helicopter Ever designed to fly on another planet) on 18 February.
