The Week in Science: Astronauts and Biopsies

I slept a bit later today, so my writing time is short.  Let me capture a few snippets.

--I think of the Artemis mission astronauts heading back to Earth today.  I read about all the processes that have to happen for them to have a safe return and not burn up in re-entry or sink to the bottom of the ocean.

--Earlier this week, when war drums rattled with what seemed to be threats of nuclear annihilation, I thought of the astronauts who might have to stay in space longer--but how long is possible?  I thought of all the songs and novels that have stranded astronauts as part of the plot.  Happily these space travelers are returning to a world that has not been decimated by a nuclear weapon.

--It has been a good teaching week, as last paper assignments start to come together.  But we're all tired.  It's palpable.

--I had three spots biopsied when I went to the dermatologist in March.  Happily, two of them are benign, but the one on my back is a Basal cell carcinoma. So I go in later today for additional scraping and burning (but no stitches). And happily, no melanoma.  Not a huge deal--I'm at the point when I feel lucky that it can be done in the office, with no stitches. And it's not a melanoma.
