planet b


Launch of the Planet-B spacecraft took place from Kagoshima Space Center on an M-V vehicle on July 4, 1998. Flight operations will be handled by Sagamihara Spacecraft Operations Center, and Martian orbit insertion will take place in October 1999, followed immediately by data collection. Planet-B was renamed Nozomi, or "hope," after liftoff.

The two-year mission objective is to study the structure and dynamics of the atmosphere and ionosphere of Mars, including any interactions with the solar wind. The results obtained will be compared with those obtained from the Pioneer Venus Orbiter mission to better understand the direct interactions between the planetary atmosphere and ionosphere and the solar wind.
