[Key Points of the Announcement]
  • Using atmospheric models, they demonstrated that formaldehyde (H2CO), a material for life-related molecules such as amino acids and sugars, was continuously generated in the Martian atmosphere approximately 3.8 to 3.6 billion years ago.
  • It is suggested that sugar, a life-material molecule, was continuously formed in the ancient seas of Mars.
