A few hours before last week’s lunar eclipse started here in the States, the phenomenal astrophotographer (and frequent BA Blog photo contributor) Thierry Legault was in Normandy, France, and got a magnificent picture of a different sort of transit involving the Moon:
Wow. You definitely need to click to enlunanate and get the giant version. The full Moon would be enough to make this a nice picture, but look more carefully, just above the bright rayed crater Tycho. See that weird silhouette?
Hmmm. Come to think of it, the Moon is about 380,000 km away, so it’s roughly 900 times more distant than the space station in this picture. However, it’s also 35,000 times bigger, so even its much greater distance doesn’t diminish its dominance in this photo. It’s a stark reminder that we’ve explored very little of the millions of square kilometers of lunar surface.
Also on his page, Thierry has a couple of gorgeous lunar eclipse images well worth your time to look at. In fact, just go to his site and poke around. Thank me later — much later, because you’ll be there a while.

@4. ^ Gary Ansorge : Indeed. Me too.
Wow. Magnificent photo. Superb work by Thierry Legault once again.
Imagines the International Space Station was *really* orbiting the moon. Acting as an interplanetary (Interlunar? Selene-drical?) exploration spacecraft rather than just being in Low Earth Orbit. Sighs.
PS. Thanks, BA, for reminding us all in your chosen title that the word “satellite” also applies to the natural as well as the artificial bodies.

This is, without a doubt, one of the coolest photos I’ve seen this year.
It really makes you think what things will look like when or if anyone ever builds a a space station ala “2001: A Space Odyssey” at a lagrange point or something.
December 30th, 2010 at 9:07 am
This is a good addendum to your post the other day debunking the supposed space ships traveling to Earth to destroy the human race in 2012.
This is a great demonstration of the scales involved.

@MTU:
“Imagines the International Space Station was *really* orbiting the moon.”
No. Not this crap again. It cannot be done. ISS is not built to work, operate and survive in this environment. Ther is no possibility and no sense in moving ISS to orbit around Moon. Just… stop…
December 30th, 2010 at 10:01 am

December 30th, 2010 at 1:21 pm
I just had a thought (it happens from time to time): I know one of the astronauts who is either on the ISS (I still think of the station as Alpha, because that’s what the first crew called her) or was up there recently enjoyed taking photographs of the Earth’s surface from that vantage. If that camera were pointing at Normandy as Legault was taking his picture, would that not be a perfect example of the Nietzschean quote, “If you stare into the Abyss long enough the Abyss stares back at you”?
December 30th, 2010 at 2:41 pm
My first thought when I saw the pic (unmagnified) was of a TIE Fighter… I can’t be the only one right?
December 30th, 2010 at 3:19 pm
I want to be on the ISS.
December 30th, 2010 at 3:50 pm
@Tanstaafl
I decided that must be the camera exposure time.
Roughly 90 minutes per orbit.
Roughly 1/4 minute (time) to cover 1 degree (arc)
So, something like 7 seconds to pass across the moon’s disk.
At least, that’s what is on the back of my imaginary envelope.
December 30th, 2010 at 4:22 pm
I’m actually surprised the ISS is 1/35,000th the size of the Moon’s diameter. I’d have thought the Moon was bigger than that. Then again, the human brain was never designed (figuratively, non-creationistically speaking) to conceptualize such enormous sizes.
December 30th, 2010 at 7:00 pm
Re: how did he get the image without moon-saturation
..perhaps two image overlay? One of moon focus, one of ISS focus, overlay and both ceom out perfectly in focus? Just thinking….probably wrong.

Absolutely stunning picture. I am in awe of the amount of detail on the moon itself, let alone the awesomeness of the transiting ISS.
Question for everyone: What’s the peculiar bright white spot at about nine o’clock on the moon’s disk here? I’m guessing it’s just a peculiar crater (well, I’m hoping it’s not a Cyberman advance base for an upcoming invasion, anyway), but why is it so bright?

http://en.wikipedia.org/wiki/Aristarchus_(crater)
“why is it so bright?”
The impact that created it was more recent than almost any other major lunar feature’s origin (except Tycho). Aristarchus’s exposed material hasn’t had as much time to be darkened by the solar wind as most other lunar surface.
December 30th, 2010 at 11:56 pm
Re: Joel
That bright spot is Hoaglands secret base on the moon…
…or perhaps a coincidental alignment giving reflection of a crater a nice bright appearance?

I don’t have the math skills to do the calculations, but that 0.55 second IS the length of the pass of the ISS in front of the moon. I’ve watched it cross the sky, and it moves!
I’m sure M. Legault timed his shot perfectly; in fact, he may well have taken a burst of shots. The 5D can take 3.9 frames per second. As far as getting the exposure to correctly expose both the moon and the silhouette of the ISS, he just shot for the moon. The ISS is just an unlit black shape in front of it.
I want to do this! With CalSky, a great telescope, a great camera to attach to it, and a lot of practice, it could be done. In fact, this would be much easier than his amazing video captures of the ISS as it whips across the sky. If you know the ISS is going to cross in front of the moon at an exact time in a given place, then you just get to that place, aim you scope and camera at the relatively still moon, focus, take some preview shots to get the exposure right, and shoot a burst at the right time. The final shot will be great just as long as you catch the ISS in front of the big old (half a degree wide) moon (and, of course, have great seeing and a sturdy mount). For the video, you’d have to get the fast-moving ISS into the very center of your field of view, lock on it, and record the tiny shape on the tiny sensor in your planetary camera.
The newest DSLRs have such great noise reduction that you can use ISOs as high as 1600, so exposure times can be very short, freezing the moment so that bad seeing doesn’t blur the shot. I have a Canon 500D coming in the mail, and several fairly decent scopes. I think I’ll give this a try. I’ll just keep my expectations low.
I envy him his equipment, his patience, and his amazing skill!
December 31st, 2010 at 12:37 am
Wait, maybe I do have the math skills to make a guesstimate. When it crosses the entire sky (180 degrees) at a given location, the ISS takes about five minutes, or 300 seconds. The moon is about 1/2 degrees across, so, 1/360 the distance across the sky. 300/360 = .83 seconds, which is pretty close to .55. The angle was no doubt less than straight across the sky, and/or the ISS didn’t cross the entire face of the moon.
Sorry for the pedantry! Maybe I’m way off here, anyway.
December 31st, 2010 at 3:28 am
@Gary #4, @MTU #5: The Moon in the picture is full (or pretty close anyway), which means both the station and the Moon are lit equally well. The Sun is behind the photographer. That’s why the brightness of the moon does not dominate (well, not by much) the picture.
It als helps that ISS’s solar panels are always directed towards sun, which means it was probably as bright as it gets when the picture was taken.
@Monkey #28: for all practical purposes the Moon and the Station are both in ‘infinity’ range, which means they both can be pictured with same focus setting.

I love these pictures of spacecraft transiting celestial bodies. Besides the fact that they are beautiful, they inspire me in that they combine the awesomeness of space with the astonishing reminder that we are still putting things in it of our own creation, and that we coexist in a spectacular universe. Seeing them both in the same picture is also a powerful reminder that, despite our baby steps and steps backwards, we humans are still in space, man! That we are part of the universe too, and that we ill hopefully be exploring it for a long time to come.

About the problem of moon light saturating the image.
Well, it actually saturates!
Thus the ISS is totally dark in this picture, but you can see details just because the background is so clear.
About focus: probably 420 km and 380.000 km are not so different, from a scope focus point of view.
On a standard camera they would both be “infinite”, definitely.
January 5th, 2011 at 4:22 am
@36 Actually, an ISS pass lasts about 9 minutes, even almost 10, on a given location and this doubles your estimates, but of course the moon “occultation” can last much less.
Let’s say that a pass of this kind can last no more than about 1.7 seconds in the most favorable case.
Please go to http://www.amsat.org, section ‘passes’ to calculate times of passes above your location.
When this happens you can normally do two things: listen to 143.625 and 145.800 MHz FM, listening fro some activities and, if the pass is justbefore dawn or little after sunset, SEE the ISS with the naked eyes, as a bright star passing by. I bet you will impress your friends!
