Expedition 43 Flight Engineer Samantha Cristoforetti of the European Space Agency (ESA) photographed the giant solar arrays on the International Space Station on Feb. 12, 2015.

The space station's solar arrays contain a total of 262,400 solar cells and cover an area of about 27,000 square feet (2,500 square meters) – more than half the area of a football field. A solar array’s wingspan of 240 feet (73 meters) is longer than a Boeing 777’s wingspan, which is 212 feet (65 meters). Altogether, the four sets of arrays can generate 84 to 120 kilowatts of electricity – enough to provide power to more than 40 homes. The solar arrays produce more power than the station needs at one time for station systems and experiments. When the station is in sunlight, about 60 percent of the electricity that the solar arrays generate is used to charge the station’s batteries. At times, some or all of the solar arrays are in the shadow of Earth or the shadow of part of the station. This means that those arrays are not collecting sunlight. The batteries power the station when it is not in the sun.

Time And Space


Here’s a paper plane to put all other paper planes to shame. This miniature model of a Boeing 777 (an Air India 777-300ER, to be specific) is the obsessively-awesomely-detailed work of Luca Iaconi-Stewart, who has been working on the project for 5 years using… wait for it… nothing but manila folders and dabs of glue. But look closely, it may be made of paper, but this jetliner is nearly as complicated as the real thing. The doors open and close on paper hinges, the landing gear retracts up into the fuselage. It’s astonishing.

The idea for the project grew out of his love of airplanes—and the “massing models” he made from manila paper in a high school architecture class. Soon after he found a super-detailed diagram online of an Air India 777-300ER, Iaconi-Stewart was drawing forms in Adobe Illustrator, printing them on manila, and wielding his X-Acto knife. “There’s something rewarding about being able to replicate a part in such an unconventional medium,” he says.

5 years may sound like a fairly long time to spend on a single project, but to give you an even better idea of the painstaking amount of effort and attention to detail involved, consider that Iaconi-Stewart spent an entire summer simply creating the plane’s seating sections: “20 minutes for an economy seat, four to six hours for business class, and eight hours for first class.”

He designed the engines in about a month and assembled them in four. The tail he rebuilt three times. When his classes at Vassar took up too much time—he actually stopped work on the 777 for two years because of college—Iaconi-Stewart dropped out. “I’m fortunate to have parents willing to give me a fair amount of latitude,” he says. They’re going to have to give a little more: When this project is finished, probably early this year, he might start building an even bigger model.

The images we’ve share here barely scratch the surface. Visit Luca’s Flickr stream for many more photos of his incredible project and click here for time-lapse process videos. Luca thinks he’ll be finished with his model early this year and is considering building an even bigger model next.

The GE90 Engine

Specifically designed for the Boeing 777, the GE90 is the world’s most powerful turbofan engine.

The GE90 series of engines are built exclusively for Boeing’s 777 aircraft. The GE90 first debuted in 1995 aboard a British Airways 777 and the early GE90 models boasted outputs between 74,000 and 94,000 lbs of thrust. GE developed the first carbon-fiber composite fan blade for the GE90 engine in 1995 and has since improved upon that with larger models (-110B and -115B variants). These larger variants are now built exclusively for Boeing’s largest 777 models (777-200LR and 777-300ER). The GE90 us now the best-selling engine for that aircraft family.
