The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000. It has been inhabited continuously since that date. The last pressurized module was fitted in 2011, and an experimental inflatable space habitat was added in 2016. The station is expected to operate until 2030. Development and assembly of the station continues, with several new elements scheduled for launch in 2020. The ISS is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurized habitation modules, structural trusses, solar arrays, radiators, docking ports, experiment bays and robotic arms. ISS components have been launched by Russian Proton and Soyuz rockets and American Space Shuttles.

The ISS serves as a micro-gravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS maintains an orbit with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It circles the Earth in roughly 92 minutes and completes 15.5 orbits per day.

The ISS is a joint project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station is divided into two sections, the Russian Orbital Segment (ROS) and the United States Orbital Segment (USOS), which is shared by many nations. As of January 2018, operations of the American segment were funded until 2025. Roscosmos has endorsed the continued operation of ISS through 2024, but has proposed using elements of the Russian segment to construct a new Russian space station called OPSEK.

Dragon is a reusable cargo spacecraft developed by SpaceX, an American private space transportation company. Dragon is launched into orbit by the company’s Falcon 9 two-stage-to-orbit launch vehicle.

During its maiden flight in December 2010, Dragon became the first commercially built and operated spacecraft to be recovered successfully from orbit. On 25 May 2012, a cargo variant of Dragon became the first commercial spacecraft to successfully rendezvous with and attach to the International Space Station (ISS). SpaceX is contracted to deliver cargo to the ISS under NASA’s Commercial Resupply Services program, and Dragon began regular cargo flights in October 2012. With the Dragon spacecraft and the Orbital ATK Cygnus, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry.

On 3 June 2017, the CRS-11 capsule, largely assembled from previously flown components from the CRS-4 mission in September 2014, was launched again for the first time, with the hull, structural elements, thrusters, harnesses, propellant tanks, plumbing and many of the avionics reused while the heat shield, batteries and components exposed to sea water upon splashdown for recovery were replaced.

SpaceX has developed a second version called Dragon 2, which includes the capability to transport people. Flight testing is scheduled to complete in the first half of 2019 with the first flight of astronauts, on a mission contracted to NASA, scheduled to occur later the same year.

The International Space Station’s High Definition Earth Viewing (HDEV) experiment is an external camera platform located on the Columbus module of the space station. In addition to providing beautiful views of Earth, one of the goals of HDEV is to monitor the longevity and quality of its image sensors in the space environment. HDEV operations began April 30, 2014 and only a single bad pixel has been identified.

The unpiloted SpaceX Dragon cargo craft arrived at the International Space Station May 6, two days after launch atop a Falcon 9 rocket from the Cape Canaveral Air Force Station, Florida. Expedition 59 Flight Engineers David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA used the Canadian-built Canadarm2 robotic arm to capture Dragon before turning the operation over to robotic ground controllers who maneuvered Dragon for its installation to the Earth-facing port of the Harmony module where it was bolted into place for a month-long stay. Dragon is delivering almost three tons of supplies and scientific experiments to the orbital outpost.
