Amazing photo shows spacewalking astronauts from the ground – Space.com

Here's a spacewalk as you've probably never seen one before.

Last Wednesday (March 23), NASA astronaut Raja Chari and the European Space Agency's Matthias Maurer spent nearly seven hours outside the International Space Station, performing a variety of maintenance work.

Amazingly, astrophotographer Sebastian Voltmer managed to capture a snapshot of the spacewalk action from the ground and from Maurer's hometown of Sankt Wendel, Germany, no less.

In photos: The most memorable spacewalks of all time

"Yesterday I witnessed the #spacewalk shortly after sunset. Here comes a first photo. #ESA #astronaut Matthias Maurer was just 'climbing' at this moment. The rod-shaped structure (Canadarm2) is the robot arm. Greetings from Matthias Maurer's hometown it was very exciting. #iss," Voltmer tweeted on Thursday (March 24).

Maurer is actually visible in the International Space Station image, as Voltmer notes in the annotated image he posted on Twitter along with the above description. And so is Chari, Voltmer added in a Sunday tweet, which he published after taking a bit more time to analyze the photo with the help of photographer Phillip Smith.

"I feel like I just made a once-in-a-lifetime image," Voltmer wrote at SpaceWeather.com, which featured the photo in its online gallery. "It's probably the first ground-based picture showing two spacewalkers on the ISS at the same time."

Voltmer used a Celestron 11-inch EdgeHD telescope on a GM2000 HPS mount and an ASI290 planetary camera to get the shot, he told Space.com via email. You can find more of his work at his Instagram page and learn more about him here.
