This week, we are—or I am, at least—saying "never say 'never.'" Our lead story is also on the cover of Scientific American's latest (and freshly redesigned!) print edition, and makes a thorough, thought-provoking argument for why we'll never live in space. Personally speaking, I wouldn't bet on our becoming truly extraterrestrial anytime soon. But I wouldn't bet against it, either. "Never," after all, is a very strong statement to make, extending as it does into the unknowable depths of eternity. But enough about my opinions; read the article, then share what you think! Elsewhere, we have stories on strangely discordant black holes, next steps in NASA's studies of unidentified anomalous phenomena, spacecraft-smacking solar outbursts, and much more. Be sure to also read this week's blast-from-the-past "From the Archive" selection, which in 2016 offered an expert-authored overview of the OSIRIS-REx asteroid sample return mission now slated to drop its precious payload back on Earth this Sunday, circa 11am Eastern Daylight Time. |
