40 Years after Apollo 11: July 21

Originally written on July 21th, 2009…

Neil and Buzz, after spending about 20 hours on the Moon, head back up to join Mike in the command/service module. And as we’ve seen almost every step of the way with Apollo, they’ve left behind the part of their ship they won’t need anymore to save on fuel. All that’s coming back up to orbit is 44 pounds of rocks and soil, Neil, Buzz, and 10,000 pounds of aluminum and steel to keep them alive and safe. Once the two ships have docked, Neil and Buzz will move all their stuff – and their prized lunar samples – over to the command/service module. Then they’ll eject the lunar module, leaving it to orbit the Moon. A few hours later, they’ll fire the big rocket on the end of the service module to escape the Moon’s gravity and head home to Earth (that little blue thing off in the distance.)

40 Years after Apollo 11: July 20 – Landing Day!

Originally written on July 20th, 2009…

While working on this little chronicle, there have been days when I’ve really had to search to find pictures that were definitely from that day. Not so here. Around 300 pictures were taken on the surface of the Moon on this day 40 years ago. I’ll try to find a few of the less common ones.

But first, a note about the landing. It almost didn’t happen.

Neil and Buzz were heading for the surface, the lunar module’s rocket firing all the way, as there was no atmosphere to use to slow their decent. The rocket had to fire, and it had to fire all the way down. And that meant it was using fuel. And there was only so much room for fuel. That will become a problem in a minute.

Early in the decent, other problems were cropping up. The antenna, which was supposed to automatically point back to Earth, kept moving a little off the mark, causing the signal to drop out. Then Houston would have to call Mike in the command module and ask him to relay info to Neil and Buzz in the lunar module. Just when that problem was settling down…

“Program alarm!”

As you may know, the guidance computer in the lunar module was less powerful than an iPhone. How were they able to use something so primitive to do something so complex as land on the Moon? For one thing, the LM computer was only programmed to land on the Moon. It didn’t have a fancy graphic display, its user interface was a keypad with about as many keys as an ATM, and it could not be used to open a Word doc (not that any existed.) All it did was take input from the sensors on the LM and make small adjustments to the attitude and speed of the ship as it descended towards the Moon.

But now, suddenly, on the little pocket calculator-like display of the computer, Neil and Buzz saw “1202.” That may not seem ominous, but in the literally hundreds of hours of simulator time they’d been through, they’d never seen that code pop up!

Back on Earth, someone knew what “1202” meant. For every person sitting at a console in Mission Control, there was a whole room full of people in another part of the building to support that person. One of those guys, Steve Bales, was in charge of knowing everything there was to know about the LM computer’s program. He quickly called his guy in Mission Control. “We’re go on that.” And the call went up to Neil and Buzz. “We’re go on that alarm.” That’s all they needed to hear.

Later, they would find out that the alarm went off because the computer was overloaded. You see, they’d forgotten to turn off the radar used to dock and undock with the command module, so the computer was getting too much input and running out of memory. Apollo 11 was almost scuttled due to the ’60’s version of a spinning rainbow beach ball.

Now they were close to the surface, and Neil saw another problem. The area where they were supposed to land was strewn with 10-foot tall boulders. Not a good place to set down. So he grabbed the controls from the computer and pushed the ship forward. They were skimming across the lunar surface, Neil looking for a safe place to land, Buzz calling out the ever decreasing fuel numbers. Finally, Neil found a good spot, eased the speed back, and landed the LM. With about 15 seconds of fuel left.

After everything was shut down, Neil took the first picture from the surface of the Moon.

Neil got out first. After saying his (possibly) flubbed historic line, “That’s one small step for [a] man, one giant leap for Mankind,” he took this first picture while on the surface. That bag there is called a “jett bag.” Since weight is at such a premium, the astronauts throw out their trash. Yes, first picture, and you can see we’re already litterbugs.

AS11-40-5850

Neil took this picture of Buzz coming down the ladder after him. The surface of the Moon is very bright. It’s like one big bounce board. That’s why Buzz shows up so well in this picture, even though he’s in the LM’s shadow. That’s also why you don’t see any stars in Moon pictures. In order to take a picture of something bright (like the surface of the Moon,) you have to use a fast shutter speed and close the iris down on the camera. Otherwise everything would be washed out. Under those conditions, starlight is far too faint to show up.

AS11-40-5868

Here’s the plaque on the side of the lander. It says, “Here men from the planet Earth first set foot upon the Moon. July 1969, A.D. We came in peace for all Mankind.”

AS11-40-5899

And then, kinda-sorta opposite to that, we have Buzz in front of the American flag. Why does it stand straight out like that, even though there’s no air (and therefore no wind) on the Moon? Well, they planned ahead. You can see the horizontal bar at the top of the flagpole. The flag is attached to it and it’s holding it out. It looks a little crumpled at the bottom because the flag is made of lightweight nylon fabric, and in that light gravity, it doesn’t even have enough weight to straighten itself out. Also, they didn’t pack an iron aboard Apollo 11.

AS11-40-5875

Here Buzz is checking the little cheat sheet attached to his suit’s wrist. This is one of the most iconic photos from Apollo 11. The version here is the original, a little tilted, not exactly framed, and with the LM leg visible. That gold pole sticking into the middle of the frame is a landing probe. There was one on the bottom of each LM leg, so they’d know exactly when they made contact with the surface.

AS11-40-5903

Just for fun, here’s a less iconic image from that day. Just like vacation photos, not every snap deserves a frame.

AS11-40-5916

This shot gives you a sense of scale. That huge 363 foot tall Saturn V rocket was needed just to get this lightweight little ship to the Moon. But they’re going to leave the Moon with even less spaceship than they came with. Only the top part of the LM, the part not covered in foil, is going to blast off from the Moon.

AS11-40-5927

And that’s it. After 2 1/2 hours on the Moon, Neil and Buzz went back inside. On later Apollo flights, the astronauts would stay on the surface longer, do multiple EVA’s, and even sleep in the LM. But this was the trial. This was to answer the question, “Can we even do this?” Here’s the face of the first man to walk on the Moon to give you an answer.

AS11-37-5528

Neil and Buzz will stay on the surface for a few more hours, then they’ll start the long journey home.

40 Years after Apollo 11: July 19

I wrote a series of posts about Apollo 11 on the 40th anniversary of the mission back in 2009. It’s a cool story. So here it is again, day by day, using only pictures I could confirm were taken on the day in question…

Apollo 11 has arrived in lunar orbit. As they swung around the far side of the Moon, they fired the service module rocket to slow them down enough to be captured by the Moon’s gravity.

AS11-37-5439

Now, Neil and Buzz have floated over to the lunar module and separated from the command/service modules. (Here the LM is upside down, rotating so Mike in the command module can make sure everything looks okay.)

AS11-44-6598

From the lunar module, Neil and Buzz can look back at Mike, who is now the most alone person in the universe.

40 Years after Apollo 11: July 18

I wrote a series of posts about Apollo 11 on the 40th anniversary of the mission back in 2009. It’s a cool story. So here it is again, day by day, using only pictures I could confirm were taken on the day in question…

Apollo 11 is coasting to the Moon. Of the huge 363 foot tall rocket that blasted off from Florida, only a small portion remains. As each stage of the rocket fires and uses up its fuel, it is jettisoned so they don’t have to carry the extra weight.

The command module (where the astronauts are,) service module (holding fuel, water and oxygen,) and the lunar module are the only parts of that huge original rocket that are heading to the Moon. Here, let me show you with a clip from “Apollo 13…” (Future generations: If the video doesn’t play, that’s because it’s copy-written material and someone finally noticed…)

Except for the particular astronauts and the tension of whether or not Kevin Bacon could dock it (which was wholly created for dramatic purposes,) that’s pretty much how it went on Apollo 11.

Now that the lunar module is attached, the astronauts have gone in to check it out and make sure everything survived the shock and vibration of launch.

Here’s Buzz in the lunar module, taking out his sunglasses as the bright sun is shining through the windows.

The weight of the lunar module had always been an issue. Every pound of weight meant more fuel needed to land on the Moon. Since there’s no atmosphere on the Moon, you can’t glide in like a space shuttle or use parachutes. You have to fire the rocket to slow your descent, and KEEP firing it all the way down. Every pound was more weight the rocket would have to support.

My uncle worked at Grumman while they were building the lunar module. He said there was a company wide contest: if anyone could find a legitimate way to shave one pound off the lunar lander, they would get a $1,000 bonus (back then, enough to buy a car!)

Everything you see in this picture is somehow incredibly vital to landing on the Moon and keeping Neil and Buzz safe while doing it…

Safety is important, especially when home is getting so far away…

Here are Neil and Buzz in the Lunar Module flight simulator at the Cape. They kept practicing, simulating the landing, until just a couple of days before launch. They also tried to simulate every sort of emergency or glitch that could pop up. There was one that was almost missed… but we’ll get to that on July 20, landing day…
