Image of Mercury captured by NASA's Mariner 10 spacecraft, the first probe to visit Mercury.(Image credit: NASA/JPL/USGS) Even though Mercury is the closest planet tothe sun, its surface can still be extremely cold, thanks to its lack of a heat-trapping atmosphere. The temperature during ...
As the iron core of the planet cooled and contracted, the surface of the planet became wrinkled. Scientist have named these wrinkles, Lobate Scarps. These Scarps can be up to a mile high and hundreds of miles long. Mercury has a molten core. In recent years scientists from NASA have come...
NASA’sMESSENGER spacecraft, the first to orbit the planet, revealed more information than ever before, including discoveries of an unusually large core, magnetic field, and evidence of water ice on Mercury’s poles. It orbited the planet for four years before ending its mission. ...

He could travel very quickly from place to place just like the planet Mercury moves quickly around the sun. 10. Mercury’s surface has ice on it. In 2012, NASA’s MESSENGER spacecraft discovered water ice inside some of Mercury’s craters. Being so close to the sun, you might find it...
NASA's MESSENGER orbiter was the second spacecraft to visit Mercury. When it arrived in March 2011, it became the first spacecraft to orbit the planet. The mission came to an abrupt end on April 30, 2015, when the spacecraft, which had run out of fuel, purposely crashed onto the plane...
