Thanks to Ralf Vandebergh for another excellent image of ATV! Ralf has captured a number of in-flight images of ATV-3 so far and this time he’s acquired Edoardo Amaldi attached to the ISS (click on the ‘Continue reading’ link below the image to read Ralf’s comments).
We have had much luck tracking ATV on its way to the ISS: good weather during the entire trajectory from an often-cloudy country, The Netherlands. But since docking, the weather’s turned cloudy. Still, I wanted to have a docked image taken in the same window as the docking. This succeeded finally on 2 April. Although the atmosphere looked relatively steady, there were some problems with internal turbulence in the open (Newtonian-type) telescope. Additionally, you notice the recent reboosts of the station to an altitude of over 400 km in the resolution. I have taken ISS images at altitudes of 350 or even 340 km. An experienced photographer immediately notices the difference of 50 km altitude, and I wonder if the crew notices much of this difference. However, the resulting image shows some nice details so it will appear on my website for sure.
