We open with the countdown to destruction—the MESSENGER spacecraft’s impact on Mercury ended its spectacularly successful mission. Principal Investigator Sean Solomon joins us immediately after this big finish. Emily Lakdawalla adds her congratulations for the MESSENGER team, and shares exciting new images of Pluto from New Horizons. “May the fourth be with you,” says Bruce Betts on this week’s post-Empire, pre-Chapter 7 What’s Up segment.
