Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Suisei Mission

Suisei (Planet-A) was a mission to flyby comet 1P/Halley planned by Japan's Institute of Space and Astronautical Science (ISAS). Launched on 18 August 1985, Suisei carried two instruments in order to study the growth and the decay of the cometary object's hydrogen corona, and the interaction of the solar wind with the cometary ionosphere. Suisei encountered 1P/Halley on 8 March 1986 at a distance of 151,000 kilometers on the sunward side.

The spacecraft's thrusters were depleted of hydrazine on 22 February 1991 causing future planned encounters to be canceled. ISAS had planned to send Suisei by 21P/Giacobini-Zinner on 24 November 1998 and 55P/Tempel-Tuttle on 28 February 1998.

SBN lead the effort to archive the data from Suisei into the PDS.
