International Space Station: 15 Facts for 15 Years in Orbit
A new type of “sunrise” dawned above Earth on Nov. 20, 1998, with the launch of the first piece of the International Space Station.
Fifteen years ago Wednesday (Nov. 20), the Russian-built Zarya, or “Sunrise,” module, also known as the functional cargo block (FGB), lifted off atop a Proton rocket from the Baikonur Cosmodrome in Kazakhstan to begin the most complex scientific and engineering project in history.
Zarya supported orientation control, communications and electrical power for the emerging outpost. Two weeks after its launch, Zarya was joined on orbit by Unity, the station's first connecting node. [Building the International Space Station (Photos)]
It would take 13 years for the space station's assembly to be declared “complete,” although it is still being expanded. Today, the station is an active laboratory with hundreds of science experiments being conducted onboard, advancing humanity's knowledge about how to live in space and how to improve life on Earth.
To mark the 15th anniversary, SPACE.com partner collectSPACE.com compiled a countdown of 15 facts about the International Space Station.
15 Sunrises, sunsets
Circling Earth at 17,500 miles per hour (28,000 kilometers per hour) every 92 minutes, the crew members aboard the International Space Station “experience 15 or 16 sunrises and sunsets every day,” NASA's Earth Observing System (EOS) Project Office describes.
“The whole station glows with the light of dawn,” Canadian astronaut and former ISS commander Chris Hadfield told NPR in a recent interview. “You can see the dawn come across the world towards you.”
“Then you go back to work and wait another 92 minutes, and it happens again. It's not to be missed, and I tried to watch as many sunrises and sunsets as the work would allow,” he said.
- Since the launch of the first “Sunrise” (Zarya), the station has “seen” more than 175,000 sunrises and sunsets.
- 14 Rooms
- The space station today has more livable room than a six-bedroom house — spread across 14 pressurized modules or components.
There are three laboratories — the U.S. Destiny module, European Columbus module and Japan's Kibo lab — and three connecting nodes (Unity, Harmony and Tranquility). On the Russian side, there are two docking compartments (Pirs and Rassvet), the Zarya FBG and Zvezda service module. [15 Years of Space Station Science and Construction (Video)]
Quest serves as the U.S. operating segment's airlock and the Leonardo permanent multipurpose module (PMM) acts as a closet for storage space. The Kibo module also has its own supply closet (the “JLP”) and lastly is the Cupola, a seven-windowed observatory.
The space station's internal volume is about the same as a Boeing 747 jumbo jetliner.
13 Years of continuous residency
It took two years of construction before the space station was ready for tenants. The three-member Expedition One crew, NASA astronaut William Shepard and cosmonauts Sergei Krikalev and Yuri Gidzenko, arrived at the orbiting outpost on Nov. 2, 2000, and the space station has been continuously occupied ever since.
Initially, the station's crew was limited to three people, and for a period of time, that was reduced to only two. Today, the Expedition 38 crew has six members.
Over the past 4,766 days (as of Nov. 20), 88 people have lived aboard the space station as resident crew members, with another 120 or so people visiting the orbiting outpost to help with construction and deliver supplies.
12 Months for the first yearlong mission
To date, the longest expedition on board the International Space Station was 215 days and 8 hours, logged by the Expedition 14 crew of Michael Lopez-Alegria and Mikhail Tyurin from September 2006 to April 2007. Their seven months in space was one and a half months longer than the typical resident crew's stay, which averages about five and a half months in duration.
But as attention turns to sending astronauts out into the solar system, NASA and its international partners are now preparing for the first yearlong stay on the space station.
Beginning in March 2015, NASA astronaut Scott Kelly and Roscosmos cosmonaut Mikhail Korniyenko will live and work on the orbiting complex for 12 months. Their stay will further inform scientists' understanding of how the human body reacts to extended exposure to microgravity.
11 Hundred hours spacewalking
Earlier this month, two cosmonauts ventured outside the space station to mount a camera platform and perform a symbolic relay holding an Olympic torch. It was the 174th spacewalk in the space station's history, bringing the total time spent on ISS extravehicular activities (EVA) to 1,094 hours and 39 minutes, or 45.6 days.
“I remember pre-ISS talking about the hundreds, or more than one hundred, EVAs that are going to be required for assembly [of the space station] and thinking that was a huge mountain to climb,” ISS Expedition 16 astronaut Dan Tani said in December 2007 after completing the station's 100th spacewalk.
One hundred and thirteen (113) expedition crew members have donned either U.S. EMU or Russian Orlan suits to work on assembling and maintaining the space station.
10 Space agencies sending astronauts
Fifteen nations partnered to build the International Space Station — the U.S., Russia, Japan, Canada and members of the European Space Agency (ESA) — but the people who have visited the ISS have not been limited to those countries.
In addition to NASA, Roscosmos, the Japan Aerospace Exploration Agency (JAXA), Canadian Space Agency and ESA, astronauts have visited the outpost representing five other space agencies, including France's CNES, Brazil's AEB, Malaysia's Angkasa, South Korea's KARI and Italy's ASI.
9 Hundred, 25 thousand pounds in orbit
When Zarya launched in 1998, it weighed 42,600 pounds (19,300 kg). A decade and a half later, the International Space Station now masses almost one million pounds — 925,000 pounds (420,000 kg).
The station is the largest spacecraft ever assembled or flown in space, spanning the length and width of an U.S. football field.

8 Space tourist flights
Not every individual to fly to the station did so under the auspices of a country or space agency. Seven so-called “space tourists,” or “spaceflight participants,” funded their own multimillion dollar trips to the space station under an agreement with Roscosmos and the U.S. space tourism agency Space Adventures. [The International Space Station: Inside and Out (Infographic)]
California businessman Dennis Tito was the first to pay his own way to the station in 2001.
Following Tito into orbit were South African software developer Mark Shuttleworth, New Jersey entrepreneur Gregory Olsen, Iranian-American engineer Ahousheh Ansari, Hungarian-American Microsoft Office inventor Charles Simonyi, second-generation U.S. astronaut and computer game pioneer Richard Garriott and Canadian Cirque du Soleil co-founder Guy Laliberte.
- Simonyi enjoyed his first space trip in 2007 so much that he returned for another flight two years later.
- 7 Visiting vehicles
- Zarya's launch began the effort, but it wasn't until NASA's space shuttle delivered and mated the Unity module that the International Space Station was really born.

The shuttle fleet was critical to the assembly of the space station, delivering to orbit the truss segments that formed the outpost's backbone, as well as most of the modules. When the ISS was completed, the orbiters were retired.
Six other spacecraft have and continue to supply and staff the station.
Since Expedition 1 in 2000, Russia's Soyuz has been the primary means for astronauts and cosmonauts to travel to and from the outpost. Similarly, the station's primary cargo craft has been Russia's unmanned Progress craft, which on Nov. 25 will lift off for the 53rd flight to the station.
JAXA's H-II Transfer Vehicle (HTV) and ESA's Automated Transfer Vehicle (ATV) have each resupplied the station four times to date.
Most recently, NASA has contracted with U.S. companies SpaceX and Orbital Sciences to send cargo to the space station on their Dragon and Cygnus vehicles, respectively. Moving forward, the U.S. space agency is also planning to hire private spacecraft to fly its astronauts to and from the space station, with flights starting in 2017.
6 Sleep stations
Although the space station is often compared (including in this article) to the volume of a six-bedroom house, the ISS does not include traditional bedrooms for its resident crew. Rather, six phone-booth-size pods serve as sleep stations and private space for each astronaut and cosmonaut.
“Originally, they were going to put us all in one habitation module with sleep stations all around it, but the way the station was eventually built, we have sleep stations inside [Unity] Node 2, which is in the forward part of the station, and inside the service module, which is in the aft,” Chris Hadfield described in a video he filmed about sleeping in space.
“Inside each one is just a sleeping bag tied to the wall. You might think it's uncomfortable not having a mattress and a pillow but without gravity, you don't need anything to hold you up. You can just completely relax and you don't even need a pillow,” said Hadfield.

Fun ISS Facts for Kids
The International Space Station, more commonly known as the ISS is what we are going to learn about.
The ISS is the ‘International’ Space Station, which means that the space station is an international project. The ISS is not the first space station. There have been others, however what is special about the ISS is that the project is a multi national effort by a number of nations. These nations are listed below.
The space station is an artificial satellite, which means it orbits the Earth from space. The moon is an example of a natural satellite, and the difference is that the artificial satellite is man made.
The ISS was built in many stages and has been a joint effort by all the countries involved since it was launched way back in 1998. So the ISS has already been in orbit of a number of years.
The station is serviced by spacecraft from many of the participating countries. The station can carry up to 6 crew members and most of the time the station has a full crew.
So, what purpose does the ISS serve and why was the ISS built?
The purpose of the ISS is to act as a laboratory that constantly orbits the Earth in space. The station conducts many tests and experiments for the different space agencies and will also play an important role in in future missions to the moon, Mars and other places in the solar system.
The cost to build and maintain the station is very expensive, and is one of the most if not the most expensive things ever constructed.
The crew of the ISS spend most of their days on the station working on projects, with some free time for themselves in their quarters. Its not easy to eat, drink, sleep or do anything else really on the station, however there are good systems in place for the crew to manage.
The ISS is a wonderful man made creation, and its vital for future space exploration.

International Space Station Fun Facts – Online Star Register
– 21 Apr 2017
How easy is it for you to brush your teeth in the morning? Can you easily wash your face? What if the water coming from your faucet started to float? These are some of the things that the astronauts on the International Space Station deal with on their mission. Read on to learn more about the International Space Station.
The International Space Station serves as a scientific laboratory in space. Each day that passes scientists and astronauts learn more about living in space, eating in space, and space’s effects on the human body. We have listed below many interesting facts about the International Space Station.
HOW FAST DOES IT TRAVEL?
The International Space Station travels in orbit around Earth at a speed of roughly 17,150 miles per hour (that’s about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes! It Orbits the Earth 16 Times a Day.
- WHICH WAY DOES IT ORBIT?
- The ISS is prograde meaning it travels in the direction of the Earth’s rotation.
- HOW HIGH IS IT ABOVE THE EARTH?
The average distance in miles above Earth’s surface the ISS orbits is 250 kilometers. On a clear day, the ISS is easily visible to the naked eye from the ground.
WHO OWNS THE ISS?
The International Space Station is a co-operative program between Europe, the United States, Russia, Canada, and Japan for the joint development, operation and utilization of a permanently inhabited Space Station in low Earth orbit
ASTRONAUTS ON THE ISS
HOW MANY PEOPLE ARE USUALLY ON THE ISS?
There are three people permanently on the station, and the crew that rotates out periodically.
When the shuttle goes up, it carries up to seven additional people so they can have as many as ten at a time when the shuttle is there.
And when Russian ship goes up, usually there are two people aboard, so there are either three, five or ten people on the station. It is permanently manned at a level of three.
- HOW LONG DO THE ASTRONAUTS STAY ON THE ISS?
- The ISS missions, called expeditions, usually last about six months.
- HOW DO THEY CLEAN THEIR CLOTHES?
Astronauts aboard the ISS incinerate their dirty laundry through atmospheric reentry. ISS astronauts are instructed to wear their underwear for up to a week before changing to a clean pair.
Of course, the temperature-controlled atmosphere of the ISS is much cleaner than Earth’s, and the lack of gravity means clothes don’t stick to their bodies as much.
But astronauts do have to exercise frequently to prevent muscle atrophy.
DO ASTRONAUTS SHOWER ONBOARD THE ISS?
