So while doing microgravity research is technically possible, both cost, paperwork and timeliness are major factors negatively affecting the likelihood that a corporation will attempt to use the ISS to perform said research.<br /><br />I suppose we will have to wait and see, but I suspect it is likely that Bigelow has been contacted by at least a few companies/governments looking for access to his hab space. Just because corporations aren't using the ISS for research doesn't mean that they don't want to.<br /><br />
