The mission that has been in operation for 30 years has been jeopardized by the failure of the second data recorder.

NASA scientists are working with the JAXA and ISAS to determine the best path forward for the project.

Researchers at JAXA spotted the problem with the recorder. Scientists are trying to determine the cause of the damage. NASA said that attempts to recover the second recorder have so far been unsuccessful.

No one can hear the Earth's magnetic field boom.

On July 24, 1992, the "tail-region" of Earth's magnetic field was studied by the "geotail" mission. When the sun is shining.

A stream of charged particles and energy from the sun, encounter the magnetosphere, charged particles inside this structure travel along magnetic field lines and flow out in a wake behind the Earth.

The activity was monitored using a suite of equipment including the MGF and several particles instruments.

Our understanding of how energy and matter from the sun affect Earth's neighborhood and how the magnetosphere's magnetic field lines move and rebound is dependent on the understanding ofgeotail.

In addition, during a dozen close flybys of the moon early in its mission, Geotail was able to identify some elements in the moon's atmosphere.

The first data recorder to fail was on the 20th anniversary of the mission. For the past decade, the data recorder has operated alone. The original length of the mission was just four years, but it has lasted more than 30 years.
