Scott Bolton

Juno Principal Investigator and Associate Vice President of the Southwest Research Institute’s Science and Engineering Division

Have you seen its stunning image of Jupiter’s south pole? The Juno orbiter is surpassing expectations and delivering surprising science. Scott Bolton, the mission’s Principal Investigator, is back with a thrilling report. We’ve reached another key milestone along LightSail 2’s road to space. Planetary Society Digital Editor Jason Davis fills us in. Bill Nye gets from India to William Shatner in less than three minutes, and Bruce Betts escorts us across the night sky in What’s Up.

Jupiter’s south pole from Juno (multi-orbit mosaic) This image shows Jupiter’s south pole, as seen by NASA’s Juno spacecraft from an altitude of 52,000 kilometers. The oval features are cyclones, up to 1,000 kilometers in diameter. Multiple images taken with the JunoCam instrument on three separate orbits were combined to show all areas in daylight, enhanced color, and stereographic projection.Image: NASA / JPL-Caltech / SwRI / MSSS / Betsy Asher Hall / Gervasio Robles
