ISS launched in 1998 by five countries, operating in low Earth orbit. Station travels at approximately 17,700 mph in orbit. Makes 16 orbits per day, covering 700,000 km in one day. First orbital velocity is 7.9 km/s
International Space Station orbits Earth at 250 miles altitude. Station travels at 17,500 mph, completing orbits every 90 minutes. NASA uses ISS to study space living conditions
Roscosmos was formed in 1992 from merging Russian Federal Space Agency. Soviet Union achieved space milestones in 1950s-1960s including first human in space. Soviet space programs faced major disasters like 1960 R-16 missile explosion
