Mars Express: ASPERA

The ASPERA Energetic Neutral Atoms Analyser studies how the solar wind interacts with the Martian atmosphere to throw light on the mechanisms by which water vapor and other gases could have escaped from Mars in the past. The instrument uses a technique known as energetic neutral atom imaging to visualize the charged and neutral gas environments around Mars. The ASPERA Principal Investigator is Dr. Rickard Lundin, Swedish Institute of Space Science, Kiruna, Sweden.

The primary source for ASPERA data is the ESA Planetary Science Archive.

Through a cooperative agreement between ESA and NASA, the PDS Geosciences Node and the PDS PPI Node are hosting copies of the ASPERA data archive.

• Copy of ASPERA NPI and ELS Data at the PDS PPI Node (UCLA)
• Copy of ASPERA NPI Data at the PDS Geosciences Node
  • Nominal Mission
  • Extended Mission
• Copy of ASPERA ELS Data at the PDS Geosciences Node

More information about ASPERA is on the ASPERA web site.

January 10, 2007. This site now has ASPERA data, both NPI and ELS, acquired from 13 November 2003 to 31 December 2006.
