NASA scientists think an explanation for how the mysterious ‘spider’ features develop on the surface of Mars.
Over the past ten years, researchers have struggled to identify year-on-year changes in the spider-shaped features that naturally occur on the planets
After studying the images from NASA’s Mars Reconnaissance Orbiter spacecraft, but experts have identified the first signs of growth, of a Martian spring to the other, of channels that appear to have been the first signs of spiders. The channels that are a result of the same thaw-carbon-dioxide process is believed to be the form of the spin-like functions, as explained NASA’s Jet Propulsion Laboratory, in a statement.

The spiders range in size from tens to hundreds of meters, depending on the space-agency, multi-channel, usually converge at a central pit, which seems on the legs and body of a spider.
“We have seen for the first time, these smaller features that survive from year to year, and this is how the big spiders started to move,” said Ganna Portyankina of the University of Colorado, Boulder, in the statement. “These are in sand-and dune areas, so we do not know whether they continue to grow or will disappear under the moving sand.”
Scientists believe that the dunes may be a factor in the formation of the baby spiders, but also many of them from becoming full-scale spinning. In an article published in the journal Icarus Portyankina and her co-authors estimated on the basis of the growth of the smaller valleys, more than a thousand Martian years sculpting a typical spin. A Mars year takes about 1.9 earth years.

“Much of Mars looks like Utah, if you are stripped of all vegetation, but ‘spiders’ are a unique Martian landform,” said Candice Hansen of the Planetary Science Institute in Tucson, Arizona, co-author of the report, in the statement.
The spider-like terrain on the red planet’s south pole. Carbon dioxide or “dry ice”, which occurs naturally on Mars’ poles in the winter, it helps the spiders. The spring sun warms the ground under the ice, causing some carbon dioxide to thaw in a gas, which bursts from the ice and touch the ground.
The red planet’s surface is still a source of fascination for researchers. Earlier this year, NASA gave a picture of the dunes on Mars, who bears a striking resemblance to Morse code.

Mars looms ever larger in America space for the future. Earlier this year, NASA announced in May 2018 start for the construction of the Mars Insight mission to study the red planet. NASA’s Mars Reconnaissance Orbiter celebrated 10 years at the red planet on March 10.
NASA’s goal is to have a manned mission to Mars in 2035. However, the former astronaut Buzz Aldrin thinks that a slightly later target date of 2040 is more realistic. In an interview earlier this year, the Gemini 12 and Apollo 11 astronaut told FoxNews.com that in 2040, the astronauts might have visited Mars’ moon Phobos, which could serve as a kind of stepping stone to the Red Planet.
Private space company SpaceX plans to launch an unmanned mission to Mars as early as 2018, with CEO Elon Musk eyeing a manned space mission around the year 2025. Musk also hopes that people will one day settle down in a city on Mars.
