Nova analiza putanje asteroida 2001 CA21 predlaže potencijalno bržu rutu do Marsa koja bi celokupno kružno putovanje mogla skratiti na manje od jedne godine. Studija objavljena u Acta Astronautica ukazuje na dve moguće putanje u 2031. od oko 153 i 226 dana, ali obe zahtevaju brzine i tehnologije izvan današnjih mogućnosti. Koncept je zasad teorijski, ali može pomoći u planiranju budućih misija dok agencije rade na naprednoj propulziji i energetskim rešenjima.
Moguća Prečica Do Marsa: Nova Teorija Nudi Kružno Putovanje Kraće Od Godine Dana
NASA released thousands of new photos taken during the Artemis II mission around the moon. The astronauts selected for the mission thoroughly documented the 10-day voyage, which included an April 6 lunar flyby as they traveled more than a quarter-million miles from Earth.
Novo istraživanje sugeriše da bi modeliranje po uzoru na rane orbite asteroida moglo otvoriti bržu rutu do Marsa — i nazad — koja bi, u idealnim uslovima, trajala manje od jedne godine za ceo kružni put.
Šta je otkriveno?
Marcelo de Oliveira Souza, kosmolog sa State University of Northern Rio de Janeiro, proučavao je ranu predviđenu putanju bliskog Zemlji asteroida 2001 CA21. U članku objavljenom u časopisu Acta Astronautica on navodi da bi humanoj letelici bila moguća slična, vrlo direktna trajektorija do Marsa ako bi se lansiranje pažljivo tempiralo u odnosu na orbite Zemlje i Marsa.
Mogućnosti za 2031. godinu
Souzina analiza ukazuje da bi 2031. mogla ponuditi povoljan prozor za dve verzije kružnog putovanja sa ukupnim trajanjem od približno 153 i 226 dana. To su znatno kraći periodi od uobičajenih planova koji, zbog čekanja orbitalnih prozora, često traju oko tri godine za povratnu misiju sa ljudskom posadom.
Međutim, obe varijante zahtevaju brzine i performanse daleko iznad onoga što današnje rakete i sistemi za sletanje mogu da pruže.
Tehnička ograničenja i praktičnost
Souzin predlog je zasad uglavnom teorijski: traži veoma visoke brzine pri prelasku između orbita, kao i napredne sisteme za usporavanje i sletanje na Mars. To znači da bi, iako trajektorije postoje u računarskim modelima, njihova primena zahtevala ključna tehnološka unapređenja pre nego što postanu praktične za posade.
Kako se ovo uklapa u planove NASA
NASA koristi programe poput Artemis za prikupljanje iskustva u slanju ljudi i opreme dublje u svemir, što bi moglo pomoći pripremama za buduće misije na Mars. Separatno, agencija planira lansiranje prve nuklearno-pogonjene letelice nazvane Space Reactor-1 oko 2028. godine, sa planiranim dolaskom do Marsa oko 2030. Ta letelica bi mogla rasporediti tri helikoptera slična Ingenuity-ju radi izviđanja potencijalnih mesta sletanja i detekcije podzemnih izvora vode.
Fisioni nuklearni pogon na letelici mogao bi biti ključan na Marsu gde prašne oluje mogu danima ili nedeljama smanjivati efikasnost solarnih panela, čineći stabilan izvor energije važnim za misije i eventualne ljudske aktivnosti.
Zaključak
Ideja da se iskoriste prirodne orbite asteroida kao „prečice“ do Marsa je intrigantna i potencijalno korisna za planiranje budućih misija. Ipak, ostaje veliki jaz između teorijskih modela i trenutnih inženjerskih mogućnosti. Dalja istraživanja i tehnološki razvoj biće neophodni da bi se ovakve rute ostvarile u praksi.

NASA released thousands of new photos taken during the Artemis II mission around the moon. The astronauts selected for the mission thoroughly documented the 10-day voyage, which included an April 6 lunar flyby as they traveled more than a quarter-million miles from Earth.

The crew of Artemis II captured a breathtaking image of a celestial event known as an "Earthset," in which the Earth dropped below the lunar horizon. The image is reminiscent of the iconic "Earthrise" photo that NASA astronaut Bill Anders captured in 1968 during the Apollo 8 mission that showed our planet rising on the lunar horizon.
Artemis II Commander Reid Wiseman of NASA took this stunning photograph of Earth from the Orion spacecraft's window on April 2. The image is reminiscent of the iconic "blue marble" image captured during the Apollo 17 mission in 1972.
In this new image from the Artemis II crew, NASA explains that what is depicted is the "divide between night and day, known as the terminator, cutting across Earth."

One of the most well-known photographs of Earth, the "blue marble" image was taken by the crew of the final Apollo mission (Apollo 17) as the crew made its way to the moon in 1972.
Voyager 1's 1990 photo of Earth, widely referred to as the "pale blue dot," was taken at a distance of 3.7 billion miles from the sun, making it the first photo taken beyond all the planets in our solar system. This image was created in 2020 or the 30th anniversary of the iconic picture using modern image-processing software and techniques to revisit the well-known Voyager view.
Because the International Space Station orbits so close to Earth's atmosphere (about 250 miles high,) the outpost and the astronauts who have lived aboard it have been the source of plenty of spectacular photos of our planet for 25 years. This recent photo, taken April 6, 2026, shows auroras glowing over the Indian Ocean.
