Bigelow’s BEAM Could Stay on ISS Longer, See Greater Use

BEAM was attached to the International Space Station (ISS) last year for a two-year test of inflatable module technology. At present, it’s not being used by the crew, but the company’s Tweet hints at possible uses and a longer mission.

SpaceNews has a bit more information:

In a statement to SpaceNews Jan. 18, company founder Robert Bigelow said more details about any agreement with NASA about extended use of BEAM would be released at a later date. “We are excited that BEAM may serve multiple uses that could extend its time attached to station well beyond the original two-year expected period,” he said. “We will be happy to provide more specifics as this process develops shortly.”

NASA spokeswoman Cheryl Warner said Jan. 18 that the agency was still in discussions with Bigelow about “next steps” for BEAM. “The BEAM demonstration is providing valuable data regarding how the materials and an expandable structure perform in the space environment,” she said. “We are in discussions with Bigelow Aerospace to evaluate the next steps for the module.”

Robert Bigelow has previously suggested there was commercial interest in the module. As a NASA press conference in April 2016 prior to the launch of BEAM, he said there were four different groups, both countries and companies, interested in flying experiments in BEAM. “We’re hoping that, maybe in half a year or something, we can get permission from NASA to accommodate these people in some way,” he said then.

The current plan is to detach the BEAM from its berthing port in 2018 and destroy the module in Earth’s atmosphere. That will free up the port for other uses.

NASA issued a request for information last year about commercial modules that could attached at that port and at other locations on the space station. The agency hopes the new modules could form the basis of a permanent commercial space station once ISS is decommissioned, which is scheduled for 2024.

It’s unlikely that any of the commercial modules would be ready to fly by the time the original BEAM experiment is scheduled to end. So, there would be time available to both extend the module’s time on orbit and use it experiments.

    That’s pretty cool. The Axium guys will not be pleased.

      I doubt it. BEAM is too small and lacks the capabilities to be a permanent module. This would be an extension until something better is available for the Node 2 docking port. Axiom wouldn’t be ready to fly next year, so a BEAM extension won’t directly affect their plans.

      Bigelow has proposed attaching a B330 to the station, but I don’t think it would be attached where BEAM is now. I don’t think there’s enough room at that part of the station to accommodate something as large as the B330.

      Also remember that ports other than the Node 2 one are available as long as the company replaced the port they are using with one at the other end of their module.

      Axiom wasn’t going after that berthing port anyway. They are interested in Harmony Forward, where PMA-2 is right now.

        It would be interesting if Axion and Bigelow can be pair and then attached to a port. I suspect that both are going to be modified over time for living quarters.

    It’s a little frustrating that astronauts always cluster in the centre of BEAM for photo-ops. Combined with the black stripes it greatly reduces the apparent internal size of the module. (Both width and length.)

    http://www.leonarddavid.com

    I don’t think I’ve seen a photo taken diagonally across the interior, nor one of an astronaut at the actual back of the module. And I’ve only seen one photo where astronauts have even their legs outside the central truss.

          Astronaut at the end of the BEAM and legs not in core. And the lower left image on the “ingress” set is basically a diagonal shot. BEAM is not very big.

            Ah, then no. That’s not what I meant.

            The astronaut in the centre two shots is not at the actual end. That end-cup is a metre or so deep. I meant you never see an astronaut next to the cup, outside the truss-frame, at the very end of the module.

            And diagonal, I meant a shot from inside the module, corner to opposite corner. The last shot comes close, but you can see by the rail to the right of frame that the photographer is still inside the central truss, not against the wall of the module.

            The type of shots taken, combined with the line markings on the walls and that end cup, make it look much shorter and narrower than it is. (The actual walls are a good metre of so beyond either side of the central frame. But is looks like the inside is a narrow tube, rather than a spherical shape.)

              The lower left and lower right images in the ingress set – the astronauts are in the “cup” area. The one on the lower right is actually “sitting” within it. Click on the image, it opens full sized in a new tab, you’ll see what I mean.

              I’m not sure you’d get a better idea of the size from a diagonal picture from within the module. It is fairly small.

                It’s over 3m wide, and 4m long.

                How big is the room you’re in right now?

                Those are its external dimensions. Its internal dimensions are smaller, it has a pressurized volume of 565 cubic feet (16 cubic meters), per https://www.nasa.gov/featur

                The walls of Bigelow modules are about 18 inches (0.45 m) thick, two walls would be 36 inches or .91 meters. Let’s assume the berthing port and bulkhead at the end of the module are half that. With expanded external dimensions of 4 m length x 3.23 m diameter, the walls give the module internal dimensions of roughly 3.55 length x 2.32 m diameter. Input those numbers for the volume of a cylinder gives us about 15 cubic meters, on the order of what the actual volume is. I presume the wall thicknesses on the berthing port and the bulkhead on the end of the module are actually thinner than 18 inches, which probably makes up the majority of the discrepancy, and the curve of the walls the rest.

                Dug around a bit and found a video of the ingress, where they have a video camera inside BEAM and are moving around, from 1:08 to 1:50 you can get a feel for the size of it.

                A few neat pictures in the NSF thread.

                The video shows my point. When the camera is against the rails of the central truss, there’s a lot of gap between the rails and the walls, which is not apparent in the photos because of the optical illusion created by the black lines. And when the astronaut is working in the “cup”, when he “sits” on the edge, he reaches his full torso length, with arms slightly above his head, to reach the back of the “cup”.

                The photos give a deeply false impression of the size of the BEAM. Making it look much smaller than it is.

                It is still pretty small. Just eyeballing it, from a rail to a wall is about the same distance, perhaps a bit less, as it is from one rail to another.

                from a rail to a wall is about the same distance, perhaps a bit less, as it is from one rail to another.

                Or nearly three times the apparent width in the photos. Which was my original point… 12 posts ago.

    I always figured they wouldn’t just dump it.

    It may be small, but there’s a LOT you could do with it. For example, something along these lines could be cool: https://uploads.disquscdn.c

    McAfee does not like that website. You may want to find out why and correct it.

    No McAfee is the anti-virus software organisation. It runs a black list of sites. Somehow your site is on the blacklist.

    McAfee in now owned by Intel.
