Jezero na Marsu

Post by Vjetar »

NASA-in rover Perseverance trebao bi - nadamo se, uspješno - sletjeti u krater Jezero, koji je dobio ime po istoimenoj opštini u Bosni i Hercegovini, a koja se nalazi nedaleko od Mrkonjić-Grada.

Glavni cilj NASA-ine misije je da istraži moguće znakove drevnog života na Marsu.
Opština Jezero se uveliko priprema za događaj koji će biti itekako značajan za BiH, a odnosi se na odličnu promociju naše zemlje.

"U toj lokalnoj zajednici, uvažavajući epidemiološku situaciju, intenzivno se pripremamo da obilježimo ovaj događaj. Ono što je zanimljivo, u toku je postupak za izbor novog grba i simbola opštine.

Jedan od prijedloga koji je ušao u uži izbor bi u svom sastavu imao i simbol Marsa, što bi moglo pomoći i turističkoj promociji opštine", za portal Radiosarajevo.ba izjavila je načelnica opštine Jezero Snežana Ružičić.

S obzirom na to da se radi o zahtjevnom finansijskom projektu, opština nije u mogućnosti da samostalno organizuje navedeni događaj.
"Opština, nažalost, nije sposobna da samostalno projekat organizuje, tako da se nadamo da će biti sluha u Ministarstvu i drugim organizacijama da nam u ovim idejama pomognu. Već smo pisali Srđanu Raičeviću, ministru za naučno-tehnološki razvoj, visoko obrazovanje i informaciono društvo RS, te očekujemo pozitivan odgovor", rekla je načelnica Ružičić.



Na sam dan slijetanja rovera Perseverance, opština Jezero će organizovati zajedničko praćenje historijskog događaja.

"Opština Jezero planira postaviti video-bim na kojem bismo pratili NASA prijenos, a kao i prilikom lansiranja, planiramo da okupimo djecu i da zajedno ispratimo taj događaj. Pored toga, željeli bismo u ovaj događaj uključiti tri univerziteta - u Banjoj Luci, Sarajevu i Mostaru, te da povežemo mlade ljude i studente koji se bave naukom", kazala je Ružičić.

Iz NASA-e kažu da će početak prijenosa uživo slijetanja rovera biti 18. februara u 11.15 sati prije podne po pacifičkom vremenu, a to znači da bi prijenos počeo u 20.15 sati po našem vremenu.

Ako sve bude išlo prema planu, rover bi na Mars sletio oko sat kasnije. Oni ističu da će slijetanje trajati oko sedam minuta, a raketa će u gornje slojeve Marsove atmosfere ući brzinom od oko 30.000 kilometara na sat ili oko osam kilometara u sekundi.

Ono što je izazovno u ovom slijetanju je činjenica da zbog velike daljine između Zemlje i Marsa inženjeri NASA neće moći upravljati slijetanjem, već će rover morati da sletjeti potpuno sam. Perseverance je prvi i jedini rover ikada napravljen koji ima vještačku inteligenciju da pročita teren ispod sebe i sam izabere bezbjedno mjesto za slijetanje bez ljudske intervencije.
Iako su u NASA-i uvjereni da je sistem testiran da savršeno funkcioniše, priznali su da postoji opasnost da neki od sistema zakaže, a rover da se sruši na Mars.

Podsjetimo, veza NASA i Jezera počela je 2007. godine, kada je 45-kilometarski krater na Marsu posredstvom Međunarodne unije astronoma dobio naziv Jezero, a NASA je u novembru 2018. odabrala baš ovaj krater kao cilj misije.

Rover Perseverance ili u privodu Ustrajnost ili Upornost je na daleki put poletio 30. jula prošle godine, oko 14 sati po našem vremenu, iz Cape Canaveral Air Force stanice na Floridi.

Slijetanje rovera pratite na ovom LINKU.

Misija treba trajati najmanje jednu godinu na Marsu, što je otprilike 687 dana na našoj planeti.

Zanimljivo je i da se na roveru, prvi put, nalazi helikopter Mars, a, podsjetimo, na Crvenu planetu otputovat će i mnoga imena ljudi, ali i organizacija koji su svoje ime upisali na NASA-inu listu pretprošle godine.

NASA Mars Mission Connects With Bosnian and Herzegovinian Town

On Sept. 23, 2019, Eric Nelson, the U.S. Ambassador to Bosnia and Herzegovina, presented a framed letter to the Snezana Ružičić, mayor of the Balkan municipality of Jezero. The letter, from NASA's director of Mars Exploration, James Watzin, honored the connection between the small Balkan town and Jezero Crater the landing site of NASA's upcoming Mars 2020 mission.

Today, a letter from NASA's director of Mars Exploration, James Watzin, was presented to the mayor of Jezero, Bosnia and Herzegovina, honoring the connection between the small Balkan town and Jezero Crater, the landing site for the Mars 2020 rover. U.S. Ambassador Eric Nelson delivered the letter to Mayor Snezana Ruzucic in the town, population 1,100.

"It takes an international team of experts to create and support a mission with the complexity and ambition of Mars 2020," said Watzin. "I am proud that we can now include the citizens of Jezero, Bosnia and Herzegovina, as honorary members of the 2020 team. Together, we will explore one of the most scientifically captivating as well as serene locations on Mars."

The linkage between Mars and the municipality of Jezero began with a decision by the International Astronomical Union (IAU) in 2007: That's when the organization gave the name Jezero Crater to a 28-mile-wide (45-kilometer-wide) crater on the western edge of Isidis Planitia, a giant impact basin just north of the Martian equator.

"The IAU choses to name craters with scientific significance after small towns and villages of the world," explained Ken Farley, project scientist for Mars 2020 from Caltech in Pasadena, California.

In November 2018, 11 years after Jezero Crater got its name, NASA designated Jezero Crater the landing site of Mars 2020.

"I couldn't be happier with both our future home on Mars and the location it was named after," said Farley.

Jezero township is situated on the Veliko Plivsko Lake entrance to the Pliva River. Like its Earthly namesake, the Red Planet's Jezero Crater was once home to a river-fed lake. Mars 2020 scientists believe this ancient river delta could have collected and preserved organic molecules and other potential signs of microbial life from the water and sediments that flowed into the crater billions of years ago. The mission plans to take samples of the area, caching them in tubes that will be retrieved and returned to Earth in a future mission.

Watzin elaborated in his letter to the people of Jezero:
"The Mars Exploration Program at NASA would like to recognize your town for its connection to this upcoming mission, and we hope that you will follow the endeavors of the Mars 2020 rover as it makes this journey. The rover was designed to further our understanding of the possibilities for life beyond Earth and to advance new capabilities in exploration technology. Once returned to Earth, the samples from Jezero Crater will provide a wealth of information about Mars and our solar system for generations to come."

Watzin is confident the thrill of exploration and discovery can extend the tens of millions of miles from an intriguing crater on Mars to a small community in Southeastern Europe. More than 300 citizens and students of Jezero and two adjacent municipalities, Jajce and Mrkonjić Grad, shared their enthusiasm for the mission during the event with the U.S. Embassy and U.S. Army Civil Affairs team. Students from both schools performed a play, "We Are Going to Mars," and experimented with robots provided by the U.S. Embassy.

"Part of NASA's mission is to inspire scientists, engineers and explorers," said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington. "Jezero's connection with the Mars 2020 mission may very well inspire students in Jezero, and elsewhere in Bosnia and Herzegovina, to pursue an education in the sciences."

Mars 2020 will launch from Cape Canaveral Air Force Station in Florida in July of 2020. It will land at the small Bosnian and Herzegovinian town's namesake, Jezero Crater, on Feb. 18, 2021.

NASA's Jet Propulsion Laboratory in Pasadena, California, is building and will manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters. Caltech manages JPL for NASA. NASA will use Mars 2020 and other missions, including to the Moon, to prepare for human exploration of the Red Planet. The agency intends to establish a sustained human presence on and around the Moon by 2028 through NASA's Artemis lunar exploration plans.
