Apollo 17, then and now

By Phil Plait | September 9, 2011 10:17 am

Last week, NASA released new, higher-res images of three Apollo landing sites taken by the Lunar Reconnaissance Orbiter. BABloggee Rick Sheppe had a cool idea: why not compare these to ones taken by the Apollo astronauts themselves? In fact, by grabbing a frame taken by a 16mm movie camera on board the Apollo 17 ascent module as they left the Moon, you can compare the views seen by astronauts and LRO directly!

So I did it. I took a frame from the 16mm camera on Apollo 17, and the LRO pic of the same area. After rotating and adjusting the contrast of the original Apollo 17 picture a wee bit, here is what I got:

Coooool. The original Apollo 17 picture is on top, and the LRO pic on bottom.

If you’re curious, NASA has labeled some of the features in the Apollo pic. In that original picture you can clearly see the bottom half of the lunar module on the surface (the bug-like landing module had two parts; a lower half (the descent stage) that stayed on the Moon to save weight, and an upper half (the ascent module) that is what carried the astronauts back to orbit, and is where the camera was that took this shot), as well as several craters, boulders, and the scuffed surface tracks from the astronauts’ boots and the rover as they ambled and rode across the Moon.

It's been too long since we walked on the Moon

BABloggee Jason Marsh sent me an interesting picture he put together. He was thinking about what was current in our culture when Apollo 17 went to the Moon… the last time a human set foot on another world.

The date was 1972. Here’s what he put together:

Hmmm. Gas lines. Viet Nam. Nixon. Elvis with Nixon. Disco.

It’s been too long. We need to go back. I certainly hope the President and Congress can figure out how; my biggest gripe about Obama’s space plan (scroll down to Point #4 in that link) is ignoring the Moon for other goals. I think we do need to go back to the Moon, create a base and then a colony there, and use that knowledge to go to asteroids and beyond (even concurrently, to tell the truth).

Posters like this one really drive the point home. It’s been too long.

… and the flag was still there

This is very, very cool: The Lunar Reconnaissance Orbiter, currently orbiting the Moon just 50 km off the surface, has taken more shots of the Apollo 17 landing siteand has seen the actual U.S. flag!

Behold (and salute):

Well, lookit that! It’s fuzzy and small and hard to be sure it’s the flag in the picture, but there it is. It does match maps made of the Apollo 17 landing site, so it’s definitely the flagpole we’re seeing there.


Compare this picture to that taken by the 16mm movie camera on the Ascent Module right after Apollo 17 lifted off the Moon; you can see many of the same features. I spent a minute looking for the rover in the LRO picture, then remembered that the astronauts moved it well off to one side, about 100 meters, before they left the Moon so that the video camera on board could record their ascent (it was remotely controlled from Earth by an operator named Ed Fendell, who had tried to film the launch of Apollo 15’s and 16’s Ascent Module but missed; with Apollos 15 and 16 technical issues prevented the ascent from being filmed, but with 17 he made it, and that’s the movie you always see in documentaries). However, you can see it in this larger overview from LRO:


[Again, click to make a giant leap.]

Incredible. The LRO page on this has more details, including comparisons of the images from LRO to ones taken in situ from Apollo 17. Remember too that these LRO images have a resolution of 50 cm (18 inches) per pixel!

Wow. Wowee wow wow.

Back to the flag, there’s a curious thing about it. The flag itself was nylon, and that tends to get brittle when exposed to ultraviolet light — which is relentless and plentiful on the airless Moon (the thermal pounding it’s taken between day and night can’t help either). I’ve often wondered what we’ll find when we go back to the Apollo landing sites; I half-expect to see red, white, and blue powder off to one side of the flagpole, and no actual flag left on the pole. This picture, as frakkin’ amazing as it is, is still just barely too low resolution to be able to say for sure, I think. The shadow is only a pixel or so in size and so it’s hard to say what’s what.

Still, Holy Haleakala. Apollo 17’s flag. I wonder what Gene Cernan and Jack Schmitt thought when they saw this picture. And I wonder when we’ll go back.

Tip o’ the spacesuit visor to Guillermo Abramson. [Edited to add: Apparently I am late to this game. While catching up on other blogs just now, I saw that both Emily Lakdawalla and Nancy Atkinson already wrote about this!]
