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 delayed Boeing Crewed Flight Test all the way back to July

Starliner Capsule secured to Atlas Rocket

It looked like Boeing would have a fantastic April with the launch of its first crewed flight of the Starliner spacecraft. However, now it seems like we’re going to have to wait until July before we see this milestone launch from the company to the International Space Station.

SpaceX CRS-27 Dragon resupply mission launches toward the International Space Station

Hot on the heels of the splashdown of the Crew-5 mission, SpaceX launched the uncrewed CRS-27 Dragon spacecraft to resupply the International Space Station.

Liftoff atop a Falcon 9 rocket came at 8:30 p.m. EDT March 14, 2023, from Launch Complex 39A at Kennedy Space Center in Florida. The autonomous spacecraft is set to dock to the ISS about a day later to deliver some 6,000 pounds (2,700 kilograms) of supplies to the seven-person Expedition 68 crew living aboard the orbiting laboratory.

The Falcon 9 first stage that flew in support of this mission, B1073, successfully landed on the SpaceX drone ship “A Shortfall of Gravitas” less than 10 minutes after launch, which was positioned downrange in the Atlantic Ocean. This was the seventh recovery for this booster.

Overall, this was SpaceX’s 17th launch of 2023 — the 16th for a Falcon 9 rocket. The company plans to fly as many as 100 missions this year.
