Description
Three missions, including two rovers, are arriving at Mars this month. We preview some of the unique aspects of the Mars Perseverance rover, and we explore the curious case of a giant galaxy with, apparently, no central black hole. Hear how merging black holes might use gravitational waves to shoot across the cosmos, plus a poetic sponsor, and the word Scutum is said way too many times.
Episode Sponsor
Sonnet One
Wisps of air that scarce provide life or heat
Blow with such acceleration they burn
Metallic skin on headlong rush to meet
Harsh surface where we hope so much to learn.
Rocks and sand, dense, opaque, illuminate
Eons past to SuperCam and SHERLOC.
X-rays and radar, shine and penetrate
the fog of history, turn back the clock.
To stand, or rather roll, on barren plains
with Ingenuity to test the skies
And UV lasers to dissect remains
Find the perfect sample to later rise.
O Perseverance, land safely on Mars
And further our dream of reaching the stars.
