Like other crew members on the space station, Mr. Pettit conducted experiments, talked with students and exercised for hours to maintain his health and to stave off loss of bone density. But the most eye-catching work he performed in orbit was his photography.
Most people on Earth will never get a chance to go to space. “I could try to give them a glimpse through my imagery,” Mr. Pettit said during a news conference a couple of weeks after his return.
Mr. Pettit noted that hard-core photographers always want to have a camera in hand. “I could look out the window and just enjoy the view,” he said. “But when I’m looking out the window, just enjoying the view, it’s like, ‘Oh, wow, a meteor. Oh, wow. Look at that. Man, there’s a flash there. What’s that?’ And, ‘Oh, look at that, a volcano going off.’ It’s like, ‘OK, where’s my camera? I got to record that.’”
Sometimes he set up five cameras at once in the space station’s cupola module, where seven windows provide panoramic views of space and Earth.
Space photography is often much like night photography. Stars are dim, and exposures lasting seconds or minutes are needed to gather enough photons. But in orbit, nothing is sitting still. The space station is zooming around Earth at about five miles per second, and the Earth is also rotating.
Sometimes, Mr. Pettit took advantage of the motion for artistic beauty — lights below blurring into glowing lines, while the stars above traced arcs in the sky.
