In my latest piece for The Planetary Report, I argue that we’ve largely lost the rhetorical ability to defend the unquantifiable values of space exploration—beauty, curiosity, discovery—in the face of an unrelenting focus on utilitarian pragmatism.

Credit to Sean Duffy today for showing up today and getting excited about this potential biosignature discovery. He wasn't involved in this budget process, and this is an great moment to engage and build his excitement for NASA science. Huge opportunity for science community!

Here's what I hope to see answered in today's Mars discovery announcement:
- Perseverance is facing a 23% budget cut next year — will this be reconsidered?
- Will this reignite the effort to pursue MSR?
- If not, are humans expected to return these samples? When? Can humans land at Jezero?
