Why in news?

• While speaking at the ISRO headquarters in Bengaluru, PM Modi announced that the point where the Chandrayaan-3 lander touched down on the lunar surface would be named Shiv Shakti.
• Later, ISRO chief K Somnath said that the country has every right to name the landing site.
• The Moon does not come under the jurisdiction of any one country. This raises the question about naming of points on moon’s surface.
  • In 1966, the United Nations Office for Outer Space Affairs came out with the Outer Space Treaty.
  • Setting some common principles for space exploration, the Treaty said in its Article II:
    • Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.

Existing Indian Names on the Moon

• The naming of the landing site is not the first incident.
• Several Indian names are already there on the Moon. We have a Sarabhai crater on the Moon.
• Following the 2008 mission Chandrayaan-1, a spot where the probe crashed (as it was meant to for the purposes of the mission), was named “Jawahar Sthal” after the first Prime Minister, Jawaharlal Nehru.
  • ISRO had suggested to name the impact site after Nehru. It was on his birthday the landing was made, and he had long championed undertaking scientific developments and research in India.
  • International Astronomical Union (IAU) later accepted it, making it official.

Who names landing sites on the Moon?

• International Astronomical Union (IAU)
  • The IAU is the primary organization responsible for the official naming of celestial bodies and their surface features, including those on the Moon.
    • IAU was founded in 1919. It determines some other rules for Space activities. India is among its 92 members countries.
    • Its mission is to promote and safeguard the science of astronomy in all its aspects, including research, communication, education and development, through international cooperation.
  • They have established guidelines and procedures for naming lunar craters, mountains, valleys, and other features.
• An informal practice of naming
  • Many mission sites first see names being given to them informally.
  • An informal practice of naming landmarks was common during the Apollo missions.
  • Names were given to the small craters and mountains near each landing site (e.g., Shorty, St. George, Stone Mountain) but official names were used as well (e.g., Hadley Rille).
    • Most of the informal names assigned during Apollo were later given “official” status by the IAU.
• Historical and Cultural References
• Lunar features are sometimes named after historical figures, scientists, astronauts, or cultural references.
• For example, many lunar craters are named after famous scientists and explorers.
• Space Agencies
  • National and international space agencies, such as NASA and ESA (European Space Agency), may play a role in suggesting names for lunar sites, especially those of significant scientific or historical importance.

How does IAU consider names for planetary objects?

• IAU’s Working Groups normally handle this process.
• These groups are made up of experts in planetary science, lunar geology, and related fields. They propose and review names for lunar features.
• Upon successful review by vote of the members of the Working Group, names are considered approved as official IAU nomenclature, and can be used on maps and in publications.
• Any objections to them can be raised by mailing the IAU General-Secretary within three months from the time the name was placed on the website.

Are there any norms for naming Space objects?

• Yes, the IAU gives several suggestions.
• For planetary objects, it states the name should be simple, clear, and unambiguous and should not duplicate existing names.
• It has a host of other rules, such as:
  • No names having political, military or religious significance may be used, except for names of political figures prior to the 19th century.
  • Commemoration of persons on planetary bodies should not normally be a goal in itself, but may be employed in special circumstances.
    • Persons being so honored must have been deceased for at least three years, before a proposal may be submitted.
