They say they have directly established (證實 ) the temperature of Mars four billion years ago. The scientists say carbonate minerals (碳酸鹽礦物 ) formed on Mars at about 18176。C. They reached the finding after studying a meteorite (隕星 ) that had its beginnings near the Martian surface. Today, the average temperature on Mars is 63176。C. The finding was reported on the website of the Proceedings of the National Academy of Sciences. Assistant Professor Woody says 18176。C is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the pla had water. Geology Professor John was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information.
