NASA Administrator Bill Nelson will appear at a committee meeting of the House Science, Space, and Technology Committee on Wednesday, and the meeting could be full of intrigue when the subject of NASA’s Artemis Program to land humans on the Moon and SpaceX comes up.

We can probably expect some happy talk as Nelson—who as a US Senator in 2011 championed development of the Space Launch System rocket alongside Kay Bailey Hutchison—references the recent stacking of the booster’s core stage with its solid rocket motors at Kennedy Space Center. After a decade and more than $20 billion in costs, NASA’s large SLS rocket is indeed finally getting closer to its first test launch.
