• Where did  the Martian water go?

  • Is it lost or simply frozen?

  • If it's lost, what enabled it to escape the planet?

  • If it's frozen, where is the tremendous amount of water stored?

These are the questions that the ASPERA-3 experiment is helping to answer through the study of the solar wind/atmosphere interaction in near-Mars space. This device is onboard the Mars Express spacecraft launched in June of 2003. No instrument with similar scientific objectives has flown or is scheduled to be flown to Mars.
