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.

Post-ISS NASA might look very different than we expected

Next year we will pass the milestone of a quarter century of a continued human presence in space thanks to the International Space Station. Led by NASA’s efforts to lead in LEO, NASA plans to take the lead in the commercial space station market as well. However, NASA’s method might not be what we expect it to be.

SpaceX shows off render of future ISS deorbit vehicle

Earlier this month, NASA selected SpaceX to be the builder of the vehicle that will be tasked with deorbiting the International Space Station in the 2030s. While no design was shared, it was said to be built on Dragon heritage hardware. In a new render, SpaceX shows off that it’s not just based on it, it’s basically just a long Dragon.

Earth-based surgeons control robot aboard ISS in historic experiment

In an experiment conducted over the weekend, surgeons stationed on Earth achieved a significant milestone by remotely controlling a small robot to perform surgery aboard the International Space Station. This highly anticipated event, involving the cutting of rubber bands as part of a surgical simulation, marks the first surgery of its kind in orbit that plays a giant leap in the development of space surgery capabilities.
