I'm super excited about returning people to the Moon. But Lunar Gateway is a bad mission architecture that really reduces the cost-effectiveness of returning to the Moon. It costs way more delta-v to reach the Gateway and then proceed to the lunar surface than just to go straight to the surface.

I really hope the new administration takes the opportunity to revise the mission architecture.
