►The ISS solar array surface will be large enough
to cover the U.S. Senate Chamber more than three times over.
►The ISS will be larger than a five-bedroom
house.
►The ISS will have an internal pressurized volume
of
46,000 cubic feet, or about 1.5 Boeing 747s.
►The solar arrays wingspan (240 ft) will be
longer than
that of a Boeing 777 model 200/300 model, which is
212 ft.
►Fifty-two computers will control the systems on
the
ISS.
►Forty-three space flights will have been
conducted on
three different types of launch vehicles over a five-year
period.
►Over 120 telephone-booth size rack facilities
will be installed in the ISS for operating the spacecraft systems and research
experiments.
►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.
►The ISS will weigh almost one million pounds.
That's the equivalent of more than 30 auto.
►The ISS will measure 361 feet end-to-end. That's
equivalent to the length of a football field including the end zones.
►2.6 million lines of software code on the ground
will support 1.5 million lines of flight software code.
►8 miles of wire will connect the electrical
power system.
►In the International Space Station's U.S.
segment alone, 1.5 million lines of flight software code will run on 44
computers
►communicating via 100 data networks transferring
400,000 signals (e.g. pressure or temperature measurements, valve positions,
etc.).
►The ISS will manage 20 times as many signals as
the Space Shuttle.
►Main U.S. control computers have 1.5 gigabytes
of total main hard drive storage in U.S. segment compared to modern
PCs, which have 20-40 gigabyte hard drives.
►The entire 55-foot robot arm assembly will be
able to lift 220,000 pounds, which is the weight of a Space Shuttle orbiter.
►The 110 kilowatts of power for the ISS will be
supplied by an acre of solar panels.
►Over the next 20 years, there will be 260 ISS
spacewalks. There have only been 138 spacewalks in NASA history.
