Chandrayaan-2’s orbiter or mother spacecraft has zeroed in on a crater on the moon named after 20th century’s acclaimed radio physicist Sisir Kumar Mitra. Images of the crater are among the second set of pictures of the northern craters sent by the orbiter.

The Mitra crater is on the edge of another crater. The pictures were taken by the Terrain Mapping Camera-2 around 2. 15 p.m. on August 23. The orbiter was then around 4,300 km from the moon, the Indian Space Research Organisation said in its update on Monday.

At 25 degrees Kelvin (minus 248 degrees Celsius), the northern polar region is believed to be one of the coldest spots in the solar system.

The first set of pictures of August 21 came from the camera on the lander which is riding atop the orbiter. The lander is set to separate from the orbiter on September 2 in preparation for its landing on the moon on September 7.

Prof. Mitra (1890-1963) also lends his name to the S. K. Mitra Centre for Research in Space Environment of the University of Calcutta.
