The five most shocking discoveries on Mars

The five most shocking discoveries on Mars

October 15 |

On July 31, 2008, the National Aeronautics and Space Administration (NASA) of the United States (U.S.) announced that laboratory tests carried out by the Phoenix mission on Mars proved the existence of water on the so-called red planet.

The U.S. agency dedicated to explore space reported that the robotic arm of the Phoenix deposited a sample taken in an instrument in which water vapors are identified.

“We have water” on Mars, said William Boynton, scientist of the thermal analyzer of the University of Arizona, on that memorable date.

We invite you to know in this article which have been the most shocking discoveries made on Mars.

Lake of liquid water

In 2018 the Marsis radar, installed aboard the Mars Express Orbiter exploration mission coordinated by the European Space Agency (ESA), discovered a lake of liquid salt water which is presumed to be at least one meter deep, reported then the group of Italian scientists who were at the forefront of the discovery.

This important finding is the first sign of liquid water on the fourth planet of the solar system. In the past, Mars had water, however, the cooling of the planet and its weak atmosphere caused it to disappear or turn into ice.

The automatic interplanetary multi-platform station Mars Reconnaissance Orbiter discovered last May 13, 2018 some “giant spiders” on the surface of the red planet.

The “arachnids” correspond to a carbon dioxide ice cap which, once the sunlight hits it, reproduces the false image of the aforementioned animal.

The blue sunsets of the red planet

NASA’s robot explorer Curiosity photographed for the first time the blue sunsets of the red planet. The left camera of the mechanic sent from Earth actually recorded a video of which we know its most beautiful frames.

The image, more than for its beauty, was used by scientists to study the composition and fall of the night dust on Mars, something fundamental to understand the origin of the planet.

Not only sunsets, also blue dunes

The Mars Reconnaissance Orbiter (MRO) discovered large blue dunes with green hues on January 24, 2018.

The coloration is due to methane gas accumulations along with organic molecules in rocks more than 3 billion years old. Most strikingly, the latter could suggest the presence of ancient life forms.

Life on Mars?

The long-awaited life on Mars, whether it is extinct or actually exists, has not been fully proven. So those who want to dream of a destroyed civilization that migrated to Earth must wait a little longer.

However, the Viking probes sent by NASA more than 40 years ago, especially the robotic Labeled Release, or LR, team, provided evidence that could hint at the possibility of ancient life forms, something that is still being investigated by scientists.

So why is Mars red?

Although the fourth planet in the solar system has blue sunsets and blue dunes, from Earth we observe it as red because of the high concentrations of iron oxide on its surface.

So, every time we have the possibility to see the fourth planet of the solar system from our homes, we will still see it red, and we will never be able to enjoy the blue sunsets and dunes. Unless we are ever able to visit Mars.

Devastating floods in Southern Brazil leave dozens dead and missing

The heavy rains in southern Brazil have resulted in catastrophic floods that have left at least 55 people dead and 67 missing in the state of Rio Grande do Sul. This unprecedented climatic disaster has devastated rural areas and severely impacted the state capital, Porto Alegre, this Saturday.

The overflow of watercourses and landslides have disrupted numerous routes throughout the state, affecting nearly 300 localities, many of which are isolated. The catastrophe has affected approximately 377,000 people, including 32,600 who were forced to evacuate their homes and belongings.

The rapid rise in the level of the Guaíba River inundated the historic center of Porto Alegre, one of the largest cities in the south of the country, with a population of nearly 1.4 million. According to the city hall, the river level reached 5.04 meters, surpassing the previous record of 4.76 meters set in 1941, during the worst floods recorded to date.

On Saturday, the city was in a state of chaos, with many streets submerged in water as residents scrambled to evacuate their homes.

Amidst rescue efforts, a major explosion at a gas station in the northern part of the city killed at least two people. The incident occurred when vehicles used in the operations were refueling at the flooded station, sending a thick cloud of smoke into the air.

In many places, long lines formed as people tried to board buses, while those in cars struggled to navigate through the waters. The situation also forced the cancellation of bus arrivals and departures at the city’s main station, located along the swollen Guaíba.

Porto Alegre’s international airport had suspended operations on Friday indefinitely.

In the Navegantes neighborhood in the northern part of Porto Alegre, José Augusto Moraes de Lima called on firefighters to rescue a child trapped in his home, as a leg injury prevented him from evacuating the child himself. “Suddenly, in a matter of minutes, everything was flooded. I lost everything, television, wardrobe, bed, refrigerator,” recounted the 61-year-old merchant.

Russian bombers near Alaska monitored by NORAD

The North American Aerospace Defense Command (NORAD) reported that it detected and tracked two Russian military aircraft operating near Alaska’s airspace in the United States this Thursday. According to the agency, the aircraft remained in international airspace and did not enter the sovereign airspace of the United States or Canada.

As detailed by the Russian Ministry of Defense, the nuclear bombers were escorted by at least one Su-35S and one Su-30SM during the mission. One of the planes was featured in a video published by the Russian news agency RIA Novosti, filmed aboard a Tu-95MS. Russia stated that the two planes carried out an 11-hour mission over the neutral waters of the Bering Sea, near the western coast of Alaska, escorted by armed Flanker fighters and, “at certain stages of the journey, strategic missile bombers accompanied by fighters from foreign countries.”

The map shows the route taken by the Russian planes (Photo: Arte O Globo) It’s worth noting that the Tu-95 model was launched in 1954 but did not enter service until 1956, and is currently used in the Naval Aviation units of the Russian Air Force and the Air Force of the Russian Army, as well as in the Indian Air Force. According to the specialized website Air Force Technology, the model is even older: its first flight took place in 1954, and the Tu-95 entered service just two years later.

The aircraft can reach a maximum speed of 650 km/h and has a flight range of 6,400 km. This Tupolev periodically carried out long-range patrols in NATO countries and the airspace of the United States until the end of the Cold War. In July 2010, two Tu-95MS Bear-H bombers set a new record for flight duration, with 40 hours of patrol over three oceans.

Ecuador declares state of emergency in five provinces to combat organized crime

The Ecuadorian government has declared a state of exception in the provinces of El Oro, Guayas, Los Ríos, Manabí, and Santa Elena for 60 days to combat organized armed groups amid escalating hostilities, according to Executive Decree 250 published on Tuesday.

The Armed Forces and National Police are jointly working to “maintain sovereignty and the integrity of the state.”

With this measure, the right to inviolability of the home has been suspended, meaning security authorities are permitted to conduct inspections, raids, and searches on properties where they believe members associated with armed groups may be hiding.

Authorities will also seize “materials or instruments” that could be used to commit crimes to neutralize threats.

In response to the criminal activity in the territory, the government will also establish an Anti-Criminal Investigation Force in the coming days aimed at reducing intentional homicides.

The national director of Crimes Against Life, Violent Deaths, Disappearances, Extortion, and Kidnapping of the National Police (Dinased), Freddy Sarzosa, noted that the main cause of criminal violence is linked to drug and arms trafficking.
