Why in News?-
- Russia’s space agency, Roscosmos, recently launched the Luna-25 mission to the Moon, while India’s Chandrayaan-3 mission was launched earlier.
- Luna-25 was launched from Russia’s Vostochny spaceport on August 11, 2023, and its lunar lander is expected to reach the Moon on August 23, the same day Chandrayaan-3 is also scheduled to land on the lunar surface.
- Both missions are expected to land on the lunar surface around the same time.
Will it hamper Chandrayaan-3 mission?-
- Roscosmos has stated that the two missions will not impede each other’s functions or collide, as they have different planned landing areas.
- According to Roscosmos, there is enough space on the Moon for both missions to operate without interference.
Different Landing Areas and Stages of Luna-25 Mission
- Roscosmos clarified that Luna-25 and Chandrayaan-3 have distinct landing areas.
- Luna-25’s landing on the Moon is planned in several stages.
- The flight trajectory to the Moon will take about 1 hour and 20 minutes, followed by a five-day flight from Earth to the Moon.
- Luna-25 is expected to stay in lunar orbit for five to seven days, depending on the selected landing area.
- Three landing areas have been designated: the primary site north of the Boguslavsky crater, and two backup sites south of the Manzinus crater and the Pentland-A crater.
ISRO’s Chandrayaan-3 Mission and Lunar Exploration
- India’s space agency, ISRO, plans for the Chandrayaan-3 lander and rover to touch down near the lunar South Pole region on August 23.
- The mission aims to explore the Moon’s surface and contribute to lunar research.
- As of July 2023, there were six active lunar orbiters, with China’s Yutu-2 rover being the only operating rover on the Moon’s far side.
Potential for Cooperation and Future Lunar Exploration
- While Roscosmos has had no direct interaction with ISRO regarding the Luna-25 project, it remains open to potential cooperation between the two space agencies.
- Roscosmos expressed interest in India’s participation in the International Scientific Lunar Station (ILRS), a planned lunar base pursued by Roscosmos and the Chinese space agency.
- Additionally, Roscosmos is exploring the possibility of placing Russian scientific payloads on future Indian lunar exploration missions, indicating a potential avenue for collaboration in lunar research and exploration.

- Luna 25, also known as Luna-Glob-Lander, is a Russian lunar lander mission.
- Launched on August 10, 2023, with the target landing site being the Moon’s South Polar Region.
Scientific Objectives:Luna 25 has two primary scientific goals:
- Study the composition of the polar regolith (lunar soil).
- Study the plasma and dust components of the lunar polar exosphere (thin atmosphere).
- The lander consists of a four-legged base housing landing rockets and propellant tanks.
- An upper compartment contains solar panels, communication equipment, onboard computers, heaters, radiators, and scientific instruments.
- Equipped with a 1.6 meter-long Lunar Robotic Arm (LRA) for regolith collection.
Lunar Robotic Arm (LRA):
- LRA can remove and collect surface regolith to depths of 20 to 30 cm.
- The arm has four degrees of freedom/rotations: azimuthal, shoulder, elbow, and wrist/scoop.
- It is equipped with a scoop and a sample acquisition tool for studying the lunar soil.
Science Instruments:Luna 25 carries eight science instruments, including:
- ADRON-LR: Gamma-ray and neutron spectrometer.
- ARIES-L: Detects charged particles and neutrals in the lunar exosphere.
- LIS-TV-RPM: Infrared spectrometer for studying water and OH on the surface.
- LASMA-LR: Mass spectrometer for analyzingregolith composition.
- PML: Detector for studying dust in the lunar exosphere.
- STS-L: Panoramic and local imaging system.
- THERMO-L: Studies regolith thermal properties.
- Laser retroreflector panel for precise measurements.
Launch and Lunar Operations:
- Launched on a Soyuz-2 Fregat rocket from VostochnyCosmodrome.
- Lander designed to operate on the Moon for about one year, studying regolith and exosphere.
