Text extracted from a NASA press release 12 November 1998

12 Nov 1998
"In the first step of a two-step process, NASA has selected five proposals for detailed study as candidates for the next missions in the Agency's Discovery Program of lower-cost, highly focused scientific spacecraft.

In a unique step for this program, NASA has also decided to fund a co-investigator to provide part of an instrument to study the interaction between the solar wind and the atmosphere of Mars. It is scheduled to fly aboard the European Space Agency's Mars Express spacecraft in 2003. NASA plans to consider such investigations, categorized as "Missions of Opportunity," in all future Discovery and Explorer program Announcements of Opportunity."

"The solar wind science hardware to be built as part of the selected Mission of Opportunity is intended for an instrument called the Analyzer of Space Plasmas and Energetic Atoms, or ASPERA-3. The principal investigator for this instrument is Dr. R. Lundin of the Swedish Institute of Space Physics in Kiruna, Sweden. The co-investigator being funded by NASA is Dr. David Winningham of the Southwest Research Institute, San Antonio, TX. NASA will provide approximately $5.3 million for the electron and ion spectrometer to be prepared for launch in 2003 aboard the Mars Express mission."
