Beginning July 1, we’ll be able to see all the moon’s phases. Many of the Apollo landing sites are on the lit side of the first quarter moon. But to see these sites, you’ll have to rely on images for lunar orbiting spacecraft. On July 9, the full moon rises at sunset and July 16 is the last quarter. The new moon begins on July 23 and is the phase we’ll look forward to in August, when it will give us the total solar eclipse. The month of July ends with a first quarter moon. Credit: NASA
Observing images of craters on Mars provides scientists insight into the water that carved them and the Red Planet's history of water activity.

What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
