Apollo 11 First Stage liftoff in Ultra Slow Motion

An evening pause: This footage was taken on July 16, 1969 at 500 frames per second, and shows only what happened at the base of the launch tower as the engines of the Saturn 5 rocket ignited and lifted the rocket into the air. Though the video is more than 8 minutes long, the actual events recorded lasted only about 30 seconds, beginning 5 seconds before T minus 0.

What struck me most as I watched this was the incredible amount of complex engineering that went into every single small detail of the rocket and the launch tower and launchpad. We tend to take for granted the difficulty of rocket engineering. This video will make you appreciate it again.

It is also mesmerizing. A lot happens in a very short period of time.

Bezos gives museum recovered Saturn V engines

Jeff Bezos today personally delivered to the Seattle Musuem of Flight the restored remains of two Apollo Saturn V engines that his company recovered from the ocean floor in 2013.

Over the course of two and a half years, the experts at the museum worked to stabilize the F-1 engine parts, halting the corrosion caused by the salt water. The engines were not restored, however. Rather they were conserved in their “as found” condition to preserve their full history, from the sky to the sea.

In the process, the Cosmosphere was able to reveal and research the parts’ serial numbers and identify the flight history for most of the large parts. The conservators were able to tie the components to the Apollo 11 and Apollo 12 missions in 1969 and to Apollo 16 in 1972.

The Apollo 11 components will be donated to the Smithsonian National Air and Space Museum in Washington.

The Saturn V was more noisy and ghostly than I had ever expected and it had grown much taller and certainly more threatening since last week. The venting fuel made loud hissing sounds when relief valves popped or opened up suddenly. It was very easy to let your imagination infect your brain. This is a very dangerous place and everything seems to be moving in the heavy foggy mist. There was no way to talk to each other, heck, we could barely see each other and…we hadn’t thought of this problem so we held onto each others yellow protective clothing like kindergartners crossing the street. We all wore safety helmets but they just did not make you feel like you were really safe.

This was also the first test launch of the Saturn 5, so the unknowns were significantly magnified.

NASA and Jeff Bezos today confirmed that one of the Saturn 5 first stage engines recovered from the ocean floor was from the Apollo 11 launch.
