Starship Asterisk*

And this is a detail of the ISS:

I have two more amazing images for you! Both show the same thing — the International Space Station crossing the Sun — but in different ways.

The first is, once again, from Thierry Legault:

Wow! You can clearly see the station (with Atlantis docked on the left!) as it crosses the Sun. Here’s a slight closeup:

There’s a nice sunspot pair there in the upper right; the one on the right looks like a face, actually. Cute. This shot was taken at 1/8000th of a second, which froze the action nicely. He has higher resolution pictures on his webpage for this event.

The second picture is slightly different:

It was taken by Heiko Mehring and obviously shows a series of silhouettes as the ISS and Atlantis crossed the Sun. You can clearly see the same sunspots, but the path of the spacecraft is slightly different, and the spots look a bit different as well. The equipment Heiko used was less fancy than what Thierry has, but you can still see a lot of detail in the image. It really is amazing that we can see such detail on the station from the ground!

I really want to as well.

The big yellow thing is the Sun. But look at the upper right section. See those two dark blips? The one on the left is the Shuttle Orbiter Atlantis and on the right is the International Space Station! Incredibly, Thierry caught them as they passed directly in front of the Sun! To give you an idea of how talented Thierry is, the entire transit lasted just over half a second.

Click to embiggen. I mean it, click it. The full-scale image is drop-dead incredible. Mind you, Atlantis had just started its pitch maneuver, designed to show its belly to the crew on the ISS so they can inspect it for heat tile damage. That means this image was taken shortly before the Orbiter docked with the station, on May 16th. Thierry was in Madrid specifically to get this shot.
