NASA astronaut Sunita Williams completed the #BostonMarathon in 2007 in 4:23:46 from the International Space Station while orbiting the Earth at ~17,500 mph. First person to run a marathon in space. She qualified for Boston on Earth with a time of 3:29:57 in the Houston Marathon. #WomenInSTEM
An official NASA portrait of astronaut Sunita Williams wearing a full white Extravehicular Mobility Unit (EMU) spacesuit. The bulky suit displays an American flag patch on the left shoulder, a mission patch on the right, and various controls on the chest pack; she holds the gold-visored helmet. With long dark hair framing her smiling face, she poses confidently in front of a large draped American flag against a cloudy Earth-toned backdrop, symbolizing American space exploration.A color photograph of NASA astronaut Sunita Williams captured mid-stride running on a treadmill in zero gravity, secured by a white harness and bungee cords attached to her waist and shoulders. She wears a navy blue sleeveless top and shorts, athletic shoes, and gray socks, with her curly dark hair floating weightlessly. The busy ISS module around her features blue handrails, equipment racks, cables, monitors, and various floating items.

Thailand to send aircraft carrier for flood relief as rains intensify
Thailand was preparing on Tuesday to send an aircraft carrier with relief supplies and medical teams to its south, where more heavy rain intensified the worst floods in years, which have killed 13 people and hobbled rescue and evacuation efforts.
