ExtremeTech.com has this story about newly restored nuclear test footage. From the article, “Lawrence Livermore National Laboratory (LLNL) is in the process of restoring those films, and they’ve uploaded the first batch to YouTube.”

From this story on sciencemag.org:

“NASA’s Curiosity rover usually keeps its instruments firmly focused on Mars’s ground, zapping grit with its laser or drilling cores in bedrock. But every few days, the SUV-sized robot, like any good dreamer, shifts its sights upward to the clouds.
