NASA discovers fresh 'blast pattern' near south pole of Mars
US space agency NASA has discovered a fresh "two-toned blast pattern" near the south pole of Mars, captured by the Mars Reconnaissance Orbiter (MRO). The impact crater had formed sometime between July and September 2018, NASA planetary scientist Ross Beyer said. "Itâs notable because it occurred in the seasonal southern ice cap, and has apparently punched through it," he added.
