This educational video depicts an inside tour of the International Space Station and hosted by NASA Astronaut Sunita (Suni) Williams orbiting the earth in zero gravity. During the overview, Sunita explains the station's structure which is divided into two pressurized modules sections, the Russian Orbital Segment (ROS) and the United States Orbital Segment (USOS), which is shared by many nations but funded by NASA until 2024. Roscosmos (Роскосмос), the governmental body responsible for the space science program in Russia and general aerospace research, has endorsed the continued operation of ISS through 2024, but has proposed using elements of the Russian Orbital Segment to construct a new Russian space station called OPSEK. The ESA (European Space Agency) also uses the ISS for research and experiments. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of re-boost maneuvers using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits around the earth per day. Sunita Lyn "Suni" Williams (born September 19, 1965) is an American NASA astronaut officer of Indian-Slovenian descent and holds the records for total spacewalks by a woman (seven) and most spacewalk time for a woman (50 hours, 40 minutes). Williams was assigned to the International Space Station as a member of Expedition 14 and Expedition 15. In 2012, she served as a flight engineer on Expedition 32 and then commander of Expedition 33. Space translated into Hindi and Slovenian is अंतरिक्ष and vesolje respectively.
