A Apollo XI regressou há 53 anos

 
Apollo XI foi a quinta missão tripulada do Programa Apollo e a primeira a realizar uma alunagem, no dia 20 de julho de 1969. Tripulada pelos astronautas Neil Armstrong, Edwin 'Buzz' Aldrin e Michael Collins, a missão cumpriu a meta proposta pelo Presidente John F. Kennedy em 25 de maio de 1961, quando, perante o Congresso dos Estados Unidos, afirmou que:

"Eu acredito que esta nação deve comprometer-se em alcançar a meta, antes do final desta década, de pousar um homem na Lua e trazê-lo de volta à Terra em segurança"

- Presidente JFK, 25 de maio de 61

Composta pelo módulo de comando Columbia, o módulo lunar Eagle e o módulo de serviço, a Apollo XI, com seus três tripulantes a bordo, foi lançada do Cabo Canaveral, na Flórida, às 13.32 UTC de 16 de julho, na ponta de um foguetão Saturno V, sob o olhar de centenas de milhares de espectadores que enchiam estradas, praias e campos em redor do Centro Espacial Kennedy e de milhões de espectadores pela televisão em todo o mundo, para a histórica missão de oito dias de duração, que culminou com as duas horas e quarenta e cinco minutos de caminhada de Armstrong e Aldrin na Lua.

Columbia floats on the ocean as Navy divers assist in retrieving the astronauts

     

On July 24, the astronauts returned home aboard the Command Module Columbia just before dawn local time (16:51 UTC) at 13°19′N 169°9′W, in the Pacific Ocean 2,660 km (1,440 nmi) east of Wake Island, 380 km (210 nmi) south of Johnston Atoll, and 24 km (13 nmi) from the recovery ship, USS Hornet.

At 16:44 UTC the drogue parachutes had been deployed and seven minutes later the Command Module struck the water forcefully. During splashdown, the Command Module landed upside down but was righted within 10 minutes by flotation bags triggered by the astronauts. "Everything's okay. Our checklist is complete. Awaiting swimmers," was Armstrong's last official transmission from the Columbia. A diver from the Navy helicopter hovering above attached a sea anchor to the Command Module to prevent it from drifting. Additional divers attached flotation collars to stabilize the module and position rafts for astronaut extraction. Though the chance of bringing back pathogens from the lunar surface was considered remote, it was considered a possibility and NASA took great precautions at the recovery site. Divers provided the astronauts with Biological Isolation Garments (BIGs) which were worn until they reached isolation facilities on board the Hornet. Additionally astronauts were rubbed down with a sodium hypochlorite solution and the Command Module wiped with Betadine to remove any lunar dust that might be present. The raft containing decontamination materials was then intentionally sunk.
