Labor Day Weekend Open Thread Enjoy your Labor Day holiday weekend, everyone. I’ll check in when I can. Southern Sunrise - The rising sun highlights Earth's atmospheric layers in a high-resolution picture taken August 27 by astronaut Ron Garan from aboard the International Space Station. The picture was taken as the orbiting lab passed over Rio de Janeiro, Brazil, and Buenos Aires, Argentina. Flying high above Earth, the ISS completes an orbit every 90 minutes, so astronauts see 16 sunrises each 24-hour day.
