Latest Mariner 10 Stories
Ten years ago, on August 3, 2004, NASA’s MESSENGER spacecraft blasted off from Cape Canaveral, Florida, for a risky mission that would take the small satellite dangerously close to Mercury’s surface, paving the way for an ambitious study of the planet closest to the Sun.
Traveling to remote locations sometimes involves navigating through stop-and-go traffic, traversing long stretches of highway and maneuvering sharp turns and steep hills. The same can be said for guiding spacecraft to far-flung destinations in space. It isn’t always a straight shot.
With some inspiration by the Cassini team's plans to image the Earth on July 19, scientists working with NASA's MESSENGER spacecraft orbiting Mercury are preparing to catch the Earth in a series of images taken of natural satellites around the Sun's closest planet.
According to an analysis of images provided by NASA's Mercury-orbiting MESSENGER, a period of heavy volcanic activity gave Mercury a makeover about 4 billion years ago, erasing the first 400 to 500 million years of its history.
Fifty years ago this Friday, America's space exploration ushered in a new era when NASA's Mariner 2 spacecraft became the first ever to study a planet other than our own.
Eight years ago this month, in 2004, the MESSENGER space probe was launched on a six-and-a-half year, 4.9-billion mile journey to be the first spacecraft to orbit the planet Mercury.
In Roman mythology Mercury was the “Messenger of the Gods,” – as well as a god of trade, thieves and travel. It is thus fitting – apart from the trade and thieves aspect – that the MESSENGER program has been so carefully studying the inner most planet in our solar system.
The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...
