Red Planet had ‘recent’ volcanism BBC

Mars appears to have been volcanically active more recently than previously supposed, according to growing evidence from Europe’s Mars Express orbiter.
New estimates suggest volcanoes could have been active between one million years ago and 20 million years ago, but more work is needed to refine the dates. Previous spacecraft data suggested that volcanism on Mars ceased some time around 600-500 million years ago. Some researchers even speculate Mars could be volcanically active today.
