NASA planetary scientist Chris McKay has stated an engineered bacterium under development is intended to produce feedstock for 3D printed houses, not for terraforming Mars.[^3]

McKay, of the agency's Ames Research Center, described the organism as "not very interesting, not very new yet". The comments appeared in Scientific American on 2 October 2026.

In separate remarks made during an online astronomy discussion on Friday, BRIN Space Research Center researcher Andre Pandie said the centre's equatorial observatory location provides much clearer sky views for astronomers.[^1] The observatory hosts a 3.8 metre telescope used for coordinated observations with facilities including Switzerland's Zimmerwald Observatory.[^2]
