After Glitch, New Horizons to Resume Science Operations July 7, Before Pluto Encounter

The newest maps of Pluto, as of two weeks before closest approach. A black and white reflectance map has been combined with a natural color map to produce the map in the center. Four dark patches of about the same size and spacing can also be seen in these and other recent images. Image […]

For several decades, Mars has been a busy place, with orbiters, landers, and rovers providing unprecedented views of the Red Planet. Another exciting possibility which has yet to be realized is an airplane, which could soar through […]

Muddy Mars: New Evidence for Liquid Water Flows Within Past Million Years

Illustration of debris flows inside Istok crater on Mars, which have provided evidence of large amounts of flowing water and mud in the past. The flows are very similar to ones on Earth in Arctic regions such as Iceland. Image Credit: Nature Communications

The fact that Mars used to have large amounts of liquid […]
