Blue Origin i NASA Pokreću NEO Hunter: Kako Planiraju Zaštititi Zemlju Od Asteroida

Blue Origin najavljuje saradnju sa NASA kako bi zajedno razvili koncept pod nazivom Near-Earth Object Hunter (NEO Hunter) — misiju osmišljenu da otkrije, presretne i po potrebi preusmeri potencijalno opasne asteroide pre nego što ugroze Zemlju.

Šta je NEO Hunter?

NEO Hunter je koncept koji bi koristio komercijalnu platformu Blue Ring kompanije Blue Origin u partnerstvu sa NASA-inim Jet Propulsion Laboratory (JPL). Blue Ring bi mogao da posluži kao nosač i stanica za manje letelice, ali i da primeni kombinaciju tehnika za odbranu — od ionskog snopa (ionski potisak) koji postepeno menja putanju objekta do direktnog kinetskog udara kojim se ubrzano menja orbitna putanja.

Zašto je to važno?

Ovakav pristup nadograđuje ranija postignuća svetske nauke, pre svega NASA-inu misiju DART iz 2022. godine, kada je direktni udar letelice promenio orbitu mesečastog tela Dimorphos i pokazao da je odstupanje opasnog objekta izvodljivo. NEO Hunter bi proširio alatni set dostupnih metoda i povećao brzinu reagovanja u slučaju stvarne pretnje.

Kako se NASA trenutno priprema?

NASA je od 2016. godine formalizovala rad kroz Planetary Defense Coordination Office, dok JPL prati objekte čije orbite dolaze unutar 4.6 miliona milja (oko 7,4 miliona km) od Zemlje — prag koji smatraju „potencijalno opasnim“. Takođe se radi na svemirskom teleskopu NEO Surveyor, planiranom za lansiranje najranije u septembru 2027., sa zadatkom da otkrije 90% objekata veličine oko 460 stopa (oko 140 m) i većih koji dolaze unutar ~30 miliona milja (~48 miliona km) od Zemljine orbite.

O Blue Originu

Kompaniju Blue Origin osnovao je Jeff Bezos 2000. godine, sa sedištem u saveznoj državi Washington. Blue Origin je zadobio prepoznatljivost zahvaljujući suborbitalnim letovima letelicom New Shepard, koji su trenutno privremeno obustavljeni dok kompanija radi na razvoju lunarnih sletnih sistema za NASA-in program Artemis. Prema izveštajima, kompanija je 2025. izvela više lansiranja teške rakete New Glenn, a dodatna lansiranja su planirana za 2026. godinu.

Kolika je stvarna pretnja?

Trenutno nema poznatih neposrednih pretnji po Zemlju. Ipak, nedavna viđenja meteora i rast javnog interesa podstakli su dodatne aktivnosti u praćenju i pripremi. NEO Hunter je u konceptualnoj fazi i, ukoliko bude realizovan, doprineo bi širem spektru odgovora — od ranog otkrivanja do tehničke intervencije.

Zaključak: Partnerstvo između komercijalnog sektora i NASA-e moglo bi ubrzati razvoj fleksibilnih i bržih rešenja za planetarnu odbranu, a koncept NEO Hunter prikazuje kako bi takva saradnja mogla izgledati u praksi.

Napomena: Sve informacije su zasnovane na javnim najavama i izveštajima poteklim od Blue Origina i NASA-e; detalji misije NEO Hunter još uvek su u konceptualnoj fazi i podložni su promenama.

Firefly's Blue Ghost lunar lander captures its shadow on the moon's surface after completing a successful landing March 2 near a volcanic feature on the moon called Mons Latreille. The vehicle became the first of two landers manufactured by a U.S. company to reach the moon is 2025 in crucial missions to lay the groundwork for NASA to return humans to the lunar surface in the years ahead.

Athena, the lunar lander on Intuitive Machines' IM-2 mission, captured this image of the moon's surface with Earth seen in the distance ahead of a March 6 landing attempt. While the lander was the second U.S. vehicle to reach the moon within a week, it ultimately landed on its side, which hindered much of its mission.

NASA astronaut Suni Williams is helped out of a SpaceX Dragon spacecraft March 18 following a return to Earth after a nine-month stay at the International Space Station. She and NASA astronaut Butch Wilmore crewed the Boeing Starliner, which had launched in June 2024 on a failed test flight that was meant to return them to Earth a few days later.

Butch Wilmore reacts after he and Suni Williams and two other astronauts splashed down March 18 in a Crew Dragon space capsule following their return to earth from the International Space Station off the coast of Florida. The astronauts' extended stay at the orbital outpost dominated the news cycle for months.

Launched March 31 from Florida using a SpaceX Dragon capsule, the mission became t first ever human spaceflight over the Earth's polar regions.

Pop musician Katy Perry emerges April 14 from Blue Origin's New Shepard capsule in West Texas following a brief flight to the edge of space. Perry was part of an all-women crew that also included broadcast journalist Gayle King that took the ride from Blue Origin's facility called Launch Site One. The high-profile launch attracted plenty of headlines and even drew some backlash from those who viewed the mission as a wasteful publicity stunt.

Blue Origin's New Shepard rocket carrying astronauts Aisha Bowe, Amanda Nguyen, Kerianne Flynn, Gayle King, Katy Perry, and Lauren Sanchez lifts off April 14 from Launch Site One near Van Horn, Texas. Blue Origin has since launched five more human spaceflights on the New Shepard in 2025.

Formerly called Project Kuiper, the venture has since been renamed Amazon Leo. Since its debut April launch, Amazon Leo has deployed 180 of 3,000 satellites planned for its first constellation, which could challenge SpaceX's Starlink.

A group of Blue Origin employees with their friends and families gather on the beach in Cape Canaveral for the launch of Blue Origin's second New Glenn rocket in 2025. Following its January debut, the rocket launched for the second time Nov. 13 from Launch Complex 36 at Cape Canaveral Space Force Station, sending NASA's twin ESCAPADE spacecraft on their trek to Mars.

Darkness falls Nov. 9 as a Blue Origin New Glenn rocket is prepped for its second-ever launch from the Cape Canaveral Space Force Station. Blue Origin is developing the towering rocket for heavy-lift missions that could see Jeff Bezos' company compete with Elon Musk and SpaceX.

A SpaceX Super Heavy booster carrying the Starship spacecraft lifts off Oct. 13, 2025, on its 11th ever test flight at the company's launch pad in Starbase, Texas. The launch was Starship's fifth of 2025, and second consecutive successful test flight following a year that was early on marked by explosive failures. SpaceX is developing the rocket for future missions that would help NASA astronauts land on the moon and also potentially transport the first humans to Mars.
