description Nozomi Overview
Nozomi, called Planet-B before launch, was Japan's first Mars probe, launched by the Institute of Space and Astronautical Science in July 1998. A propellant shortage after launch forced a revised multi-year trajectory using lunar and Earth flybys, and later propulsion and electrical faults, attributed in part to solar-flare damage, left the spacecraft unable to brake into Mars orbit when it arrived in December 2003. Nozomi passed by Mars and remains in heliocentric orbit, ending the mission without achieving orbit.
help Nozomi FAQ
What was Nozomi called before launch, and what was Japan trying to study?
Nozomi was called Planet-B before launch and became Japan's first Mars probe. The mission was designed to study Mars's upper atmosphere and its interaction with the solar wind.
Why did Nozomi take a revised route to Mars?
A propellant shortage after its July 1998 launch made the original trajectory impossible. Mission planners used lunar and Earth flybys to reshape the route and save fuel.
Which organization launched Nozomi?
The Institute of Space and Astronautical Science launched Nozomi in July 1998. That organization later became part of JAXA.
Did Nozomi reach Mars orbit?
Nozomi did not enter Mars orbit because propulsion and electrical problems prevented the final approach. The mission was formally abandoned in 2003.
