> Artemis’ Orion has been designed with an array of features to protect both humans and hardware in a worst-case scenario. A stowage bag or other material found onboard might be used to construct a temporary radiation shelter inside the spacecraft.

> As per NASA, the crew might need to stay in this storm shelter for at least a day. Extreme space weather would not prevent the crew from carrying out "critical mission activities," though, thanks to the protective radiation vests.

That's good. Hope it's enough.

> During periods of severe solar activity, astronauts might potentially construct a shielded habitat using local resources, such as lunar soil, dirt, and rocks. For instance, walls about one meter thick can be built by 3D printing building blocks from lunar dust (regolith).

They'll need to pack a fair amount of equipment and spend some time setting this up, but it would be worthwhile.

The initial HLS lander should also be big enough to fit in some kind of hardy radiation protection room as well. Astronauts on a moonwalk should have enough warning time to return to the lander and take shelter.
