We’ve got Mars and Saturn at sunset, The ISS is headed back for multiple passes, and we learn about more ice discovered in our solar system -- in a sort of unusual spot -- as HPR’s Dave Lawrence speaks with Christopher Phillips from the Mauna Kea Astronomy Outreach Committee for this week’s Stargazer report.

This image was released Oct. 15. The location in question, Kandinsky crater, is at Mercury's north pole, and at one time could have have water or water ice in it. It was spotted thanks to the Messenger spacecraft's Wide Angle Camera. Comparing to the image on the left, the view on the right is the same image, but has brightness and contrast enhanced to highlight the crater floor.
