Ancient asteroid strikes on Mars may have 'produced key ingredients for life'



According to a new study, if Mars' atmosphere was once right in hydrogen, ancient asteroid impacts may have produced fixed forms of nitrogen, known as nitrites and nitrates, which are 'key ingredients for life.' When NASA's Curiosity rover discovered nitrate on the Gale Crater, scientists did not know where it had come from. The study gives a potential answer to that question.
