BA 2100
The BA 2100, or Olympus, is a conceptual inflatable space habitat by Bigelow Aerospace. The larger BA 2100 would extend the volume and capabilities of the B330 module, which is under development as part of the Bigelow Commercial Space Station. As with the B330 module, the number in the name refers to the number of cubic meters of space offered by the module when fully expanded in space.
The mass of the BA 2100 could be as low as, but would more likely be "in the range of 100 metric tons". It is substantially larger than the B330, with the docking ends of the module alone estimated at approximately in diameter. The concept model showed the docking ports at both ends. The BA 2100 would require the use of a super heavy-lift launch vehicle and would require an fairing for launch. Suitable vehicles include the Block 2 version of the Space Launch System, designed for a payload capacity to low Earth orbit, or the satellite delivery version of the SpaceX Starship, planned to carry to LEO.
Pressurized volume of single BA 2100 module is, compared to volume of the whole International Space Station.
