• As of August 8, 2007 , the number of crewmembers and visitors who have traveled to the ISS included 177 different people representing 11 countries.
• Living and working on the ISS is like building one room of a house, moving in a family of three, and asking them to finish building the house while working full time from home.
• As of August 8, 2007 , there have been 64 launches to the ISS (42 Russian flights and 22 US Shuttle flights).
• At Assembly Complete, 80 space flights will have been scheduled to take place using five different types of launch vehicles.
EVA
• As of February 2007: there have been 81 Spacewalks (EVAs) (28 Shuttlebased, 53 ISS-based) totaling 498 hours and 3 minutes.
Mass
• The mass of the ISS currently is 213,843 kg (471,444 lb).
• At Assembly Complete, the ISS will be about four times as large as the Russian space station Mir and about five times as large as the U.S. Skylab.
• At Assembly Complete, the ISS will have a mass of almost 419,600 kg (925,000 lb). That’s the equivalent of more than 330 cars.
• The entire 16.4-m (55-ft) robot arm assembly will be able to lift 99,790 kg (220,000 lb), which is the mass of a Space Shuttle orbiter.
Habitable Volume

• The ISS has about 425 m 3 (15,000 ft 3 ) of habitable volume—more room than a conventional three-bedroom house. There are 9 research racks on board plus 16 system racks and 10 stowage racks.
• At Assembly Complete, more than 120 telephone-booth-size rack facilities will be installed in the ISS for operating the spacecraft systems and research experiments.
• When completely assembled, the ISS will have an internal pressurized volume of 935 m 3 (33,023 ft 3 ), or about 1.5 Boeing 747s, and will be larger than a five-bedroom house.
Physical Dimensions
• A solar array’s wingspan of 73 m (240 ft) is longer than that of a Boeing 777, which is 65 m (212 ft).
• At Assembly Complete, the ISS will measure 110 m (361 ft) end to end.
Electrical Power
• The solar array surface area currently on orbit is 892 m 2 (9,600 ft 2 ).
• At Assembly Complete, 12.9 km (8 mi) of wire will connect the electrical power system.
• Currently, 26 kW of power is generated.
• At Assembly Complete, the solar array surface area is 2,500 m 2 (27,000 ft 2 ), an acre of solar panels.
• At Assembly Complete, there will be a total of 262,400 solar cells.
• At Assembly Complete, a maximum 110 kW of power, including 30 kW of long-term average power for applications, is/will be available.
Meals
• Approximately 3,630 kg of supplies are required to support a crew of three for about 6 months.
• Based on input from ISS crew members, the most popular on-orbit foods are shrimp cocktail, tortillas, barbecue beef brisket, breakfast sausage links, chicken fajitas, vegetable quiche,
macaroni and cheese, candy-coated chocolates, and cherry blueberry cobbler. The favorite beverage to wash it all down? Lemonade.
Crew Hours
• While a year of Space Shuttle operations (seven crew members, 11-day missions, five flights per year) results in 9,240 total crew hours, 1 year of ISS operations—26,280 total crew hours
(three crew, 365 days) — is almost three times that amount.
Environmental Control
• ISS systems recycle about 6.4 kg (14 lb) or 6.42 L (1.7 gal) of crew-expelled air each day. 2.7 kg (6 lb) of that comes from the
• The ISS travels an equivalent distance to the Moon and back in about a day. That’s equivalent to crossing the North American continent about 135 times every day.
Data Management
• Fifty-two computers will control the systems on the ISS.
• The data transmission rate is 150 Mb per second downlink with simultaneous uplink.
• Currently, 2.8 million lines of software code on the ground will support 1.5 million lines of flight software code, which will double by Assembly Complete.
• In the International Space Station’s
