Physical Research Laboratory Scientists Find Three New Craters on Mars Surface

Sub: Science and tech

Sec: Space sector

Key Points:

• Discovery:
  • Scientists from the Physical Research Laboratory (PRL) in Ahmedabad have discovered three new craters on Mars.
  • The craters are located in the Tharsis volcanic region on Mars.
• Approval and Naming:
  • The International Astronomical Union (IAU) Working Group for Planetary System Nomenclature approved the names for the three craters based on PRL’s recommendation.
• Details of the Craters:
  • Lal Crater:
    • Named after Devendra Lal, a renowned Indian geophysicist and former Director of PRL (1972-1983).
    • Size: 65 km wide.
    • Coordinates: Centered at -20.98° and 209.34°.
  • Mursan Crater:
    • Named after a town in Uttar Pradesh.
    • Size: 10 km wide.
    • Location: Superimposed on the eastern side of the rim of the Lal Crater.
  • Hilsa Crater:
    • Named after a town in Bihar.
    • Size: 10 km wide.
    • Location: Superimposed on the western side of the rim of the Lal Crater.
• Scientific Importance:
  • Lal Crater:
    • Located in the Tharsis volcanic region, the entire area of the Lal Crater is covered with lava.
    • Sedimentary Deposits:
      • Geophysical evidence indicates the presence of materials other than lava, including a 45-meter thick sedimentary deposit in the subsurface.
      • This provides compelling evidence of water movement, transporting large volumes of sediment into the Lal Crater.
    • Significance:
      • This discovery confirms that Mars was once wet, as water moved significant amounts of sediment, indicating past water activity on Mars.

Conclusion:

• The discovery of the three new craters and the evidence of past water activity in the Lal Crater enhances our understanding of Mars’ geological history and its potential to have harbored life. This significant finding highlights the contributions of Indian scientists to planetary science and the study of Mars.

Physical Research Laboratory (PRL)

About:

• Establishment: The Physical Research Laboratory (PRL) was founded in 1947 by Dr. Vikram Sarabhai, who is considered the father of India’s space program.
• Location: Ahmedabad, Gujarat, India.
• Affiliation: PRL operates under the Department of Space, Government of India.

Mission:

• PRL is dedicated to advanced research in space and allied sciences. It focuses on the fundamental aspects of physical sciences, including astronomy, space science, and atmospheric sciences.
