Fourteen months before taking that celebrated first step on the moon, astronaut Neil Armstrong took a ride in a bizarre test vehicle at a training facility in Houston--and narrowly escaped death when it veered out of control and crashed.
It was May 6, 1968. Armstrong was strapped into what was called the Lunar Landing Research Vehicle (later versions were called the Lunar Landing Training Vehicle), an ungainly rocket- and jet-powered craft designed as a simulator for the lunar module that would take astronauts to the surface of the moon.
Armstrong was about 30 feet above the ground when the LLRV's rockets failed. The craft lurched violently and began to lose altitude. Armstrong struggled to regain control before deciding it was a lost cause. He ejected from the LLRV moments before it crashed and exploded, as can be seen in this video.
Despite the incident, Armstrong praised the craft humorously dubbed the "flying bedstead," saying it did "an excellent job of factually capturing the handling characteristics of the lunar module in the landing maneuver."
In fact, the simulator that nearly cost Armstrong his life may have saved his life and that of fellow Apollo 11 astronaut Buzz Aldrin the day they touched down on the moon. As the website of NASA's Dryden Flight Research Center explains:
The worth of the LLRV-LLTV program was realized during the final moments before Apollo 11 astronauts Neil Armstrong and Edwin "Buzz" Aldrin completed the first moon landing in the LM named Eagle. As the two men were getting close to the moon's surface, Armstrong saw they were nearing a rocky area. He disregarded the LM's automatic landing system and switched to manual control during the last moments of descent. Armstrong landed the LM on a safer, more suitable spot and was able to report, "Houston, Tranquility Base here...the Eagle has landed."
Liberty Bell 7 Sinks
After the second manned space mission in 1961, the Liberty Bell 7 capsule was afloat in the Atlantic ocean, awaiting recovery. Astronaut Gus Grissom reported that he heard a dull thud as the hatch blew open--the module began filling with water, and Grissom had to struggle to escape before it sank. Did Grissom "screw the pooch," as Tom Wolfe famously wrote in <i>The Right Stuff</i>? Or was there a mechanical malfunction? The world may never know.
Phobos-Grunt was a 2011 Russian mission to return a sample of soil from Mars' moon Phobos. It would have been the first such sample ever returned to earth. Because of a malfunction in the craft's propulsion system, however, Phobos-Grunt never made it out of low-earth orbit. It remained there, crippled, until early 2012, when its orbit decayed and it disintegrated in the atmosphere off the coast of Chile.
Mars Climate Orbiter Burns Up
This 1998 orbiter mission was supposed to study Mars' climate history and determine if the planet ever held life-sustaining water. But the $125 million craft never made it to Mars, burning up in the atmosphere on the day it was supposed to enter orbit. What caused the costly incident? One team of engineers had performed their calculations in metric units, while another used English units.
Soyuz 5 Lands Hard
After participating in the first in-flight transfer of cosmonauts from one spacecraft to another, pilot Boris Volynov (pictured), led Soyuz 5 back toward Earth. When the service module failed to detach, the craft plummeted toward earth upside-down, subjecting Volynov to extreme heat. The craft subsequently crashed hundreds of miles off course in the Ural mountains, breaking several of Volynov's teeth in the impact and leaving him to awaiting rescue in -38 degree (F) temperatures. He walked "a few kilometers" to a village and took shelter until help arrived. (<a href="http://www.wired.com/science/discoveries/news/2009/01/dayintech_0116">Source</a>)
Hubble Telescope Can't See
Although NASA's Hubble Space Telescope has produced incredible images of space for more than 20 years, it was nearly a failure of galactic proportions. After its launch in 1990, Hubble produced only blurry, grainy pictures due to a faulty mirror. Luckily, it was fixed three years later, and went on to capture some of the most incredible space images ever seen.
Kwangmyŏngsŏng Program Flounders
North Korea has attempted to launch its Kwangmyŏngsŏng satellites four times, and met with four failures. North Korean Umha-2 rockets, pictured, were used on the second and third launches but could not bring their satellite payloads into orbit. Fortunately, all the missions were unmanned.
H-IIA Rocket Self-Destructs
H-IIA is the launch system of the Japanese Aerospace Exploration Agency (JAXA). Its sixth launch was supposed to deliver a spy satellite into orbit, but a rocket booster failed to detach properly from the H-IIA, making the rocket too heavy to enter orbit. Ground control sent a destruct command to the rocket shortly after.
Glory Sputters Out
Climate science was dealt a blow in March 2011, when NASA's Glory satellite--which was supposed to study humans' effect on the Earth's atmosphere--failed to launch. The Taurus XL rocket carrying the observation satellite crashed into the Pacific after liftoff when Glory's protective casing didn't open.
Cluster Breaks Up
Cluster, a group of spacecraft launched by the European Space Agency (ESA) in 1995, were lost when launch vehicle Ariane 5 failed to reach orbit. The launch vehicle, on its maiden voyage, self-destructed after a software error caused it to veer off-course. What was the problem? A glitch similar to the issue that doomsayers said would bring disaster at 11:59:59, December 31, 1999. This time, however, the threat was real.
Apollo 13 'Fails Successfully'
NASA's most famous black eye came on April 14, 1970, when an oxygen tank on Apollo 13's service module exploded and the crew narrowly managed to abort the mission safely. The damaged service module that began the drama is pictured here, courtesy of <a href="http://www.alanbeangallery.com/">Alan Bean</a>, Apollo astronaut and "first artist on another world."
Naro-1 was a carrier rocket created for South Korea's Korean Aerospace Research Institute. Both attempts to launch Naro-1 ended in failure, with one disintegrating in the atmosphere and another exploding before making it to space.
