The four astronauts of the private Ax-4 mission to the ISS represent four different countries, so the food they're carrying up has a very international flavor.
Building on the Moon is a challenge we have yet to fully grasp. Plenty of projects have grandiose plans from using blood sweat and tears to create bricks out of regolith to building towers to wirelessly transmit power between isolated locations. However, these projects all but ignore one of the most important types of material we use commonly here on Earth - ceramics. A new paper from Dr. Alex Ellery, an Engineering professor at Carleton University in Ottawa, discusses why ceramics are so critical to the development of the lunar economy, and points to further developments in materials science that must be completed in order to manufacture and utilize them on the surface of the Moon.
