On NASA's Day of Remembrance, we pause to remember of those who gave their lives to advance the cause of exploration. As we push the edge of the envelope in this new era of exploration, NASA will uplift their legacies by embracing our core value of safety.

Lots of Moon action this month—and we don’t just mean Orion’s journey! On the evening of Dec. 1, the Moon will appear very close to Jupiter. A few days later, it’ll cover up Mars and end the month by sliding past Saturn and Jupiter. Our What’s Up! guide has all the details.
