This facility could replace the International Space Station

Vast Space has unveiled its proposed design for a facility that it says can replace the International Space Station (ISS), which will be decommissioned in 2031 after more than three decades in near-Earth orbit.

According to a video (below) released by California-based Vast Space this week, Haven-2 would — just like the current ISS — consist of multiple modules and be built up over several years. But compared to the ISS, the new station would feature a more modern, clutter-free environment for astronauts to live and work.

The first module of Haven-2 could be fully operational by 2028, thereby ensuring an overlap of operations between the existing facility and the new one.

After that, Vast will send more advanced and efficient life support technologies via additional modules. The new station will even get a module almost identical to the ISS’s Cupola, the panoramic window from which astronauts are able to make Earth observations and take photos of our planet. It will also receive a robotic arm — like the Canadarm 2 at the ISS — to assist with maintenance and upgrade work to the exterior of the facility.

“Haven-2 is being designed with compatibility in mind, ensuring that international partners can integrate seamlessly into this next-generation platform,” said Andrew Feustel, a Vast adviser and veteran NASA astronaut with over 23 years of experience and three ISS missions under his belt. “This vision of global cooperation in space will create opportunities for scientific and technological advancements, benefiting new and current sovereign partners, as well as industries around the world.”

Before that, Vast Space wants to prove its ability to build a functioning space station by launching the Haven-1 module in 2025. Haven-1 is a single-module facility that can host up to four astronauts at a time, and will be the first commercial space station to reach orbit if Vast Space is able to stick to its plan.

With NASA considering a number of proposals for the ISS replacement, a successful deployment of Haven-1 would surely boost Vast Space’s chances of being selected by the space agency to construct the larger and more complex Haven-2 facility for operations in near-Earth orbit.

SpaceX just launched a private crew to orbit — watch the highlights
SpaceX launches Fram2 private mission on March 31, 2025.

SpaceX has just launched its first private crew to orbit since the Polaris Dawn mission in September 2024.

A Falcon 9 rocket launched the Fram2 crew from the Kennedy Space Center in Florida at 9:46 p.m. ET on Monday, March 31.

NASA’s Starliner astronauts say they’d ride the spacecraft again
NASA’s Boeing Crew Flight Test astronauts (from top) Butch Wilmore and Suni Williams pose on June 13, 2024 for a portrait inside the vestibule between the forward port on the International Space Station’s Harmony module and Boeing’s Starliner spacecraft.

“We were always coming back, and I think people need to know that.” So said NASA astronaut Butch Wilmore as he and fellow astronaut Suni Williams took questions for the first time since returning from their longer-than-expected stay in orbit.

Wilmore and Williams flew to the International Space Station (ISS) in June 2023 in the first crewed flight of Boeing’s Starliner spacecraft. The test mission was only supposed to last eight days, but technical issues with the spacecraft prompted NASA to bring the vehicle home empty, leaving Wilmore and Williams waiting for a ride home.

SpaceX is about to launch its first private human spaceflight mission in nearly seven months.

The mission, set to lift off on Monday evening, will use a Falcon 9 rocket and Crew Dragon spacecraft to send four civilians into a polar orbit, in what will be a first for a human spaceflight mission.
