MESSENGER will orbit Mercury for one Earth year following two flybys of that planet. The orbital phase will use the flyby data as an initial guide to perform a focused scientific investigation of this enigmatic world. According to NASA “The MESSENGER mission will investigate key science questions using an optimized set of seven miniaturized instruments plus the spacecraft communication system:

- What is the origin of Mercury's high density?

- What are the composition and structure of its crust?

- What is Mercury's tectonic history, and is its surface shaped by volcanism?

- What is the nature and origin of Mercury's magnetic field?

- What are the characteristics of the thin atmosphere and miniature magnetosphere?

- What is the nature of the mysterious polar caps?"

       The MESSENGER mission is managed for NASA by the Johns Hopkins University Applied Physics Laboratory in Laurel, MD. The path of the satellite will start with a single gravity assist flyby of Earth, two of Venus, and three of Mercury, before going into orbit about Mercury in 2011. The spacecraft will reach escape velocity of 25,000 mph, 35,000 km/hr. The schedule is the following:

       - 2008/08, Earth flyby

       - 2006/10, Venus flyby

MUSES.....Japan, ISAS, satellite, scientific, HEO. MUSES-A, HALCA or HITEN, a small lunar probe, was launched into Earth orbit on January 24, 1990. MU SPACE ENGINEERING SPACECRAFT. The spacecraft was then known as MUSES-A, but was renamed to HITEN once in orbit. The 430 lb probe looped out from Earth and made its first lunar flyby on March 19, where it dropped off its 26 lb midget satellite, HAGOROMO. Japan at this point became the third nation to orbit a satellite around the Moon, joining the Unites States and USSR. The smaller spacecraft, HAGOROMO, remained in orbit around the Moon. An apparently broken transistor radio caused the Japanese space scientists to lose track of it. HAGOROMO's rocket motor fired on schedule on March 19, but the spacecraft's tracking transmitter failed immediately. The rocket firing of HAGOROMO was optically confirmed using the Schmidt camera (105-cm, F3.1) at the Kiso Observatory in Japan. HITEN made multiple lunar flybys at approximately monthly intervals and performed aero-braking experiments using the Earth's atmosphere. HITEN made a close approach to the moon at 22:33 JST (UTC+9h) on February 15, 1992 at the height of 423 km from the moon's surface (35.3N, 9.7E) and fired its propulsion system for about ten minutes to put the craft into lunar orbit. The following is the orbital calculation results after the approach: Apoapsis Altitude: about 49,400 km Periapsis Altitude: about 9,600 km Inclination : 34.7 deg (to ecliptic plane) Period : 4.7 days.
