What Spacecraft Visited Mercury?

After Mariner 10, it took until 2004 for another spacecraft to orbit Mercury: the MESSENGER mission (MErcury Surface, Space ENvironment, GEochemistry and Ranging). MESSENGER successfully completed an exhaustive map of Mercury’s surface as well as confirmed water ice in polar craters. Europe and Japan’s joint BepiColombo probe is gearing up for its seven-year journey to…

How Mercury Gets Into Water

Mercury released into the air from coal-fired power plants, burning household waste or mining ore deposits can reach soil and water resources where bacterial processes may transform it into organic mercury-methylmercury forms. Methylmercury travels up the food chain, poisoning fish and wildlife that humans then ingest as well as finding its way into our drinking…

Is Mercury in Retrograde Today?

Mercury governs communication, and approximately three to four times every year it appears to move backwards – this phenomenon is known as Mercury Retrograde periods. Mercury Retrograde spans nine weeks and runs between Sagittarius and Capricorn, creating an alternating back-and-forth motion, offering the opportunity to review goals and dreams, according to McCord. Now is an…

How Earth Is Like Mercury

Like Mercury, rocky planets may undergo changes due to internal forces which push and pull at crustal material, creating landforms such as volcanoes, mountains, and canyons. These forces are known as tectonics and may contribute to landform formation such as volcanoes. Scientists have various hypotheses as to what caused Mercury’s scarred surface, one being its…
