![]() Four different cargo spacecraft deliver science, cargo and supplies: Northrop Grumman’s Cygnus, SpaceX’s Dragon, JAXA’s HTV, and the Russian Progress.A spacecraft can arrive at the space station as soon as four hours after launching from Earth. ![]() Eight spaceships can be connected to the space station at once.The 55-foot robotic Canadarm2 has seven different joints and two end-effectors, or hands, and is used to move entire modules, deploy science experiments and even transport spacewalking astronauts.Eight miles of wire connects the electrical power system aboard the space station.The space station is 356 feet (109 meters) end-to-end, one yard shy of the full length of an American football field including the end zones.space shuttles and five on Russian Proton/Soyuz rockets. The large modules and other pieces of the station were delivered on 42 assembly flights, 37 on the U.S.The solar array wingspan (356 feet, 109 meters) is longer than the world’s largest passenger aircraft, the Airbus A380 (262 feet, 80 meters).Astronauts and cosmonauts have conducted 232 spacewalks (and counting!) for space station construction, maintenance and upgrades since December 1998.To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day.The living and working space in the station is larger than a six-bedroom house (and has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window).The acre of solar panels that power the station means sometimes you can look up in the sky at dawn or dusk and see the spaceship flying over your home, even if you live in a big city.Peggy Whitson set the U.S. record for spending the most total time living and working in space at 665 days on Sept.In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets.An international crew of six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes.The space station has been continuously occupied since November 2000.243 individuals from 19 countries have visited the International Space Station.
