Martian Blueberries

According to Researchers from Physical Research Laboratory, Ahmedabad the Blueberries in India and “Martian Blueberries” share similar characteristics.

What are Martian Blueberries?

  • Martian blueberries are small spherical haematites.
  • The Mars rover “Opportunity” discovered them in 2004 on the planet Mars.

Composition of Martian blueberries:

  • Martian Blueberries are made of iron oxide compounds called haematites.
  • These haematites are known to form in oxidising environments through precipitation from aqueous fluids (water like fluid).
  • Hence, the presence of haematites suggests that water was present on Mars.
  • It also indicates that the planet had an atmosphere with oxygen as haematites need oxygen to stabilise.

Similar Haematite Concentrations on Earth

  • Researchers from India have been studying the Jhuran formation in Kutch, Gujarat.
  • They have similar morphology – spherical and similar mineralogy – a mixture of haematite and goethite.
  • Further, it has been also argued that the transformation of Mars from the wet and humid to dry and arid environment is mimicked by the history of Kutch in Gujarat.
