Слайд 3


Key questions for MESSENGER Key questions for MESSENGER to answer: Why is Mercury so dense and iron-rich? What is the geologic history of Mercury? What is the structure of Mercury's core? What is the nature of Mercury's magnetic field? What are the unusual materials at Mercury's poles?

Слайд 4


What do we already know about What do we already know about Mercury? Mercury’s density is the highest of any planet It’s exotic atmosphere is the thinnest among all the terrestrial planets It is the only terrestrial planet, besides Earth, to possess a magnetic field Temperatures on Mercury vary from the highest in the solar system at its equator to among the coldest in its permanently shadowed poles

MESSENGER was launched on August 3, 2004 from Cape Canaveral Air Force Station, Florida MESSENGER was launched on August 3, 2004 from Cape Canaveral Air Force Station, Florida The probe used flybys of Earth, Venus, and is using Mercury itself to get into Mercury’s orbit The trip to Mercury is taking 7 years, but scientific research will be possible during that time.

Слайд 6


MESSENGER used gravity assists from Earth, Venus, and Mercury to lower its speed MESSENGER used gravity assists from Earth, Venus, and Mercury to lower its speed Each gravity assist changed the shape, and tilt of MESSENGER’S orbit to get it ready for orbit insertion The first of two gravity assist flybys of Venus occurred on October 24, 2006. A second of two gravity assisted flybys of Venus occurred on June 5, 2007.
