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 spiders of Mars
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.

Erin brings strong winds and storm surge despite weakening offshore
Hurricane Erin weakened to a Category 2 storm on Tuesday but continues to pose a threat to parts of the U.S. East Coast with potentially dangerous flooding, according to meteorologists.
Although the hurricane’s eye is expected to remain offshore, experts are concerned about Erin’s size, as strong winds extend hundreds of kilometers beyond the storm’s center.
In its 18:00 GMT bulletin, the U.S. National Hurricane Center (NHC) lifted tropical storm warnings for the Bahamasand Turks and Caicos Islands, but kept them in effect for parts of North Carolina.
Erin was located several hundred kilometers southeast of North Carolina and was moving northwestward.
“This means there is a risk of potentially life-threatening flooding of 60 to 120 centimeters above ground level,” said NHC Director Michael Brennan.
He also warned of the possibility of destructive waves, combined with storm surge, that could cause severe damage to beaches and coastal areas, making roads impassable.

Three U.S. Warships deploy near Venezuela to combat drug trafficking
Three U.S. naval vessels are moving toward the coasts of Venezuela, according to international media reports on Tuesday, after White House spokesperson Karoline Leavitt confirmed that President Donald Trump is ready to combat and curb international drug trafficking.
Reports indicate that the ships will reach Venezuelan waters within the next 36 hours as part of a recent U.S. deployment aimed at countering international narcotics operations.
The announcement coincides with Leavitt’s statement that Trump is prepared to “use the full extent of his power” to halt drug flows into the United States. The naval deployment involves approximately 4,000 military personnel.
“The President has been clear and consistent. He is ready to use every element of U.S. power to prevent drugs from flooding our country and to bring those responsible to justice. The Maduro regime is not the legitimate government of Venezuela—it is a narco-terror cartel,” the spokesperson said during a press conference.

Cuban authorities free salvadoran convicted in 1997 hotel bombing
Salvadoran national Otto René Rodríguez Llerena was released after serving a 30-year prison sentence for his involvement in a terrorist attack at a hotel in Cuba in 1997, the Cuban Ministry of Foreign Affairs reported.
During his trial, Rodríguez Llerena admitted to placing an explosive device at the Meliá Cohiba Hotel under the orders of anti-Castro exile leaders. He was arrested the following year when he returned to Havana with another load of explosives that failed to detonate.
“The Cuban government reiterates its commitment to combating terrorism, respecting human rights, and the need for the international community to hold accountable those who promote such acts,” the statement read.
He was released on August 15 and is the second Salvadoran to complete his sentence. In December of last year, another Salvadoran, Ernesto Cruz León, was released after planting bombs at tourist centers, one of which killed an Italian tourist identified as Fabio Di Celmo.
A third Salvadoran, Francisco Chávez Abarca, also received a 30-year sentence from Cuban courts in 2010 after being extradited from Venezuela through Interpol for actions against Cuba.
Rodríguez Llerena had requested conditional release in 2016, arguing that his actions had not caused any direct fatalities, but no further information was released about his situation until now.
