Discovering Mars: On January 25, 2004, the rover Opportunity landed on the red planet
On January 25, 2004, the rover Opportunity landed on Mars, thus beginning a mission to explore the red planet that would last 15 years.
Opportunity was the second of two rover sent to Mars by NASA (as part of the mission: Mars Exploration Rover), after the success of the Spiritmission. His main mission was to search for signs of water and conditions suitable for life, and over the years he discovered evidence of ancient water environments and collected important data about the geology and composition of the planet.
Despite the rover stopped communicating in 2019, its mission left a lasting legacy in planetary science and paved the way for further exploration of Mars.

Mars Exploration Rover
The Mars Exploration Rover was
a Mars exploration mission, where two rovers were deployed
identical: Spirit and Opportunity. The launch took place in 2003 and the rovers are
arrived on Mars in January 2004, at two different points on the planet.

Opportunity, the second Mars Exploration Rover of the NASA, reached Mars aboard a launch vehicle called "Delta II". The bright glow was so intense that it illuminated the beaches of the Florida Space Coastfor a short period of time. The Opportunity ride to Mars began with takeoff at 23:18:15. (Eastern Daylight Time from Cape Canaveral Air Force Station, Florida). The spacecraft successfully separated from the third stage of the Delta II about 83 minutes later, after being pushed out of Earth orbit and on a route to Mars.

Mission
From 24 January
2014 NASA announced that the mission of the rover Opportunity was to search for evidence of
life in the past of the planet, including a biosphere formed by autotrophic microorganisms, chemotrophs and/or chemolithotrophs , and the presence of water, including regions that
They were home to ancient rivers or lakes.

Record
Opportunity discovered the first meteorite that fell on
Another planet (Heat Shield Rock, pictured), has been analyzing the crater for two years
Victoria and in 2011 reached the crater Endeavour. The
May 19, 2010 broke the record of "longevity" of missions on
Mars, until then held by the probe Viking 1 with 6 years and 116 days
(2245 sol) to date is therefore the longest operational mission to Mars.
In March 2015, the rover exceeded 42.195 km covered on the ground
Martian, crossing the ideal finish line of the Olympic marathon.

Endurance crater
On "sol 84" on April 20, 2004, rover reached the crater Endurance (pictured) which was known to have many layers of rocks. In May, the rover circumnavigated the crater and made observations with Mini-TES and the panoramic camera. The rock "Lion Stone" has been studied and found similar in composition to the layers found in the crater Eagle.

Operation and cost
Opportunity was operational on Mars well beyond expectations: 5111 sols (14 years, 138 days) against a planned activity of 90 sols. The total cost
of the mission, for the first 90 sols of the primary mission, was 820 million
of dollars. (Photo: first color panorama sent by Opportunity, showing the landscape of Meridiani Planum)

The Six Degrees of Separation Theory, which assumes that each person can be connected to any other in the world through a chain of knowledge with no more than five intermediaries, is one of the most popular and suggestive social theories ever created, and may still be valid today in the age of social networking.
It was in the mid-1960s when a Harvard professor sent a letter to an unknown farmer in Nebraska, hoping that, through a completely random network of contacts, the letter would reach its true recipient in Boston.
Today, a study co-ordinated by the Institute of Complex Systems of the National Research Council in Florence (CNR-Isc) - signed by researchers from Spain, Israel, Russia, Slovenia and Chile - has shown that connections on social networks resemble those found by Milgram in the 1960s.

In Islam, the ḥajj is the traditional pilgrimage to the Holy Mosque in Mecca; it constitutes the fifth pillar of Islam. The pilgrimage is performed during the Dhū l-Ḥijja which is, in the Islamic calendar, the twelfth month of the year, of 29 or 30 days. In 2023, the pilgrimage is performed in the last days of June (Western calendar).
It is a pilgrimage that every Muslim is obliged to make on a compulsory basis, provided he or she has the means, first of all financial, and then physical. To date, hundreds of thousands of faithful have already celebrated the 'Tawaf of Advent', seven walks around the Kaaba, the black stone cube covered by the kiswa, an Italian silk cloth, embroidered in gold by Saudi artisans.
The significance, for followers of Islam, is to retrace the journey of Ibrahim and Ismail, i.e. Abraham and his son Ishmael in Christian and Jewish traditions.
