International Space Station

The International Space Station is a collaborative project between five space agencies: NASA, Roscosmos, JAXA, ESA, and CSA; and 16 nations. The Space Station serves as a floating laboratory in Low-Earth orbit. First launched in 1998, the station has been continually occupied by humans since 2000 and sees continual updates.

Partner Nations and Space Agencies

The International Space Station, in its name, is an international cooperation between both space agencies and nations. All these nations support funding for maintaining and providing experiments and crew for the station.

NASA and Boeing set new date for second Starliner test ahead of astronaut missions

Boeing is positioned to start flying astronauts to the International Space Station for NASA as soon as this year, but the Starliner spacecraft must complete an orbital flight test without crew. NASA and Boeing now have a new date set for when the OFT-2 mission will be conducted. If successful, Boeing’s Starliner will join SpaceX’s Crew Dragon in transporting astronauts from the U.S. to the ISS for NASA’s Commercial Crew program.

Most of us down here on Earth are aware that the International Space Station (ISS) exists and that astronauts spend about six months at a time there. But what we donā€™t seem to consider are the challenges introduced by living in such a zero-gravity environment. Thatā€™s exactly what Pablo Nespoli, an astronaut who has spent a total of 313 days onboard the ISS, decided to write a book about.
