A space history project led by Amazon.com founder Jeff Bezos has exciting news out today: Apollo mission F-1 engines have been recovered from deep beneath the surface of the Atlantic ocean, as the "F-1 Recovery Project" years in the making reaches a successful conclusion.
Here's video of the Remote Operated Vehicles recovering the engines from the ocean floor.
The F-1 rocket engine is still a modern wonder — one and a half million pounds of thrust, 32 million horsepower, and burning 6,000 pounds of rocket grade kerosene and liquid oxygen every second. On July 16, 1969, the world watched as five particular F-1 engines fired in concert, beginning the historic Apollo 11 mission. Those five F-1s burned for just a few minutes, and then plunged back to Earth into the Atlantic Ocean, just as NASA planned. A few days later, Neil Armstrong stepped onto the moon.
"We're excited to be bringing a couple of your F-1s home," Bezos said to NASA.
And Boing Boing has a statement from NASA Administrator Charlie Bolden:
It was a live broadcast, and there was a panel of scientists on one side of the studio, with us on the other. I was 23. The programming was a little looser in those days, and if a producer of a late-night programme felt like it, they would do something a bit off the wall. Funnily enough I’ve never really heard it since, but it is on YouTube. They were broadcasting the moon landing and they thought that to provide a bit of a break they would show us jamming. It was only about five minutes long. The song was called Moonhead — it’s a nice, atmospheric, spacey 12-bar blues.
This data visualization of the Apollo 11 moon mission gathers social and technical data from the 1969 lunar landing in video form. The horizontal axis is an interactive timeline.
The horizontal axis is an interactive timeline. The vertical axis is divided into several sections, each corresponding to a data source. At the top, commentators are present in narratives from Digital Apollo and NASA technical debriefings. Just below are the members of ground control. The middle section is a log-scale graph stretching from Earth (~10E9 ft. away) to the Moon. Utterances from the landing CAPCOM, Duke, the command module pilot, Collins, the mission commander, Armstrong, and the lunar module pilot, Aldrin, are plotted on this graph. The graph is partially overlaid on a composite image of the lunar surface.
This is the space suit worn by Apollo 17 commander Eugene Cernan, the last human being to set foot on the Moon.
Side note: I knew these suits were heavy. I had not realized how heavy. With 26 layers of material in the suit, a portable life-support system strapped on, and other mechanical systems attached, the whole thing weighed in at 185 pounds on Earth.
This week marks the 40th anniversary for Apollo 15, the less famous of manned lunar missions including Apollo 11, Apollo 13 ("NASA's finest hour"), and Apollo 14 (the one where Alan Shepard played golf on the moon).
Ben Cosgrove of LIFE points us to a related gallery of classic images, and explains:
While Armstrong and Aldrin walking on the lunar surface was mind-blowing, the idea of Irwin and Scott cruising around on a 450-pound moon buggy that they'd carted a quarter-million miles from Earth -- during a basically flawless mission when Scott and Irwin spent three full days on the moon's surface -- makes XV the coolest of all the Apollo missions.
