Isaacman’s corrosion comments were in response to a question about the future of the HALO module. NASA halted development of the Lunar Gateway a little more than a month ago, preferring to focus on lunar surface activities instead of a small lunar space station. The Gateway’s corrosion issues, which had persisted for months, remained a well-kept secret until Isaacman disclosed the issue. Since Gateway’s demise, Northrop has been positioning the HALO module as an option for a surface habitat, and Europe may also suggest that I-HAB be used on the surface as well. Is a fix even “warranted”? The Gateway entities have sought to minimize the habitation module damage due to corrosion, with both Northrop and Thales suggesting that the problem with the HALO module will be fixed by the end of the third quarter this year, or five months from now. However Isaacman sounds less certain about this, indicating that fixing the problem is not straightforward nor a guarantee.…
