A self-portrait, snapped by Japan Aerospace Exploration Agency astronaut Aki Hoshide, shows the wonder of space.
Aboard the International Space Station (ISS), astronaut and engineer Aki Hoshide used a digital camera to snap a self-shot while performing maintenance.
Hoshide and fellow Astronaut Sunita Williams, who can be seen in the reflection on Hoshide's helmet, were on a six-hour, 28-minute spacewalk, during which they installed and repaired a Main Bus Switching Unit and installed a camera on the space station's robotic arm, according to NASA.
Reflected in Hoshide's helmet is the Earth, while the Sun appears over his left shoulder. Sure makes you appreciate the ozone layer.
