NASA scientists pored Wednesday over stunning new images of Mercury as their MESSENGER probe began a year-long mission to map the surface of the solar system's least-understood planet.
For the first time, Earth has a regular orbiting eye-in-the-sky spying on the solar system's smallest and strangest planet, Mercury.
A desk-sized NASA spacecraft is riding the brakes all the way to Mercury, about to pull a tricky maneuver Thursday night to become the first man-made object to orbit the tiny planet.
Geologists, engineers and like-minded sceptics will meet in earthquake-devastated Christchurch Sunday to mock "junk science" predictions another major tremor will hit the city this weekend.
