Chandrayaan-3 VS. Luna-25, Russian mission. How Close Is The Moon’s South Pole?


Chandrayaan-3’s lander module is set to separate from the propulsion module, intensifying the race to the Moon’s south pole. On Wednesday (August 16), Roscosmos reported that Chandrayaan-3 is trailing Luna-25, which completed its lunar orbit. Communication is stable, and all Luna-25 systems work. Navigational factors are measured in sessions.

Chandrayaan-3 entered a crucial phase Wednesday. The ISRO reported that Chandrayaan-3 entered a 153 km by 163 km orbit after its fifth and final lunar-bound maneuver.

After today’s brief firing, Chandrayaan-3 reached a 153 km by 163 km orbit, as anticipated. Now lunar maneuvers are accomplished. The Propulsion and landing Modules must prepare for their trips on “ISRO on X (formerly Twitter).

The Space Race

Chandrayaan-3 will land first on the Moon’s south pole. Due to its fast trajectory, Luna-25 may land on the moon before Chandrayaan-3. Scientists dispute which spacecraft will land on the Moon’s south pole first.

The proximity and potential overlap of their landing dates—August 21–23 for Luna 25 and August 23–24 for The launch of Chandrayaan-3—has sparked worldwide concern.

The next phases for Chandrayaan-3

Chandrayaan-3 launched. After entering lunar orbit on August 5, orbit reductions occurred on August 6, 9, and 14. Chandrayaan-3 was lowered and raised above the lunar poles by ISRO.

The lander will detach from the propulsion module on August 17. The lander should finish the Moon’s surface journey alone following separation.

The lander must “deboost” to reach a 30 km Perilune and a 100 km Apolune.

ISRO will try a soft landing on the Moon’s south pole from this orbit on August 23. The ISRO must slow the lander from 30 miles to land. ISRO chairman S. Somanath stated the “trick we have to play” is verticalizing the spacecraft.

Chandrayaan-3 (2019) follows Chandrayaan-2 in end-to-end Moon landing and roaming.

Mission goals of Chandrayaan-3:

  • To demonstrate a soft, safe lunar landing.
  • Displaying the Moon rover and doing in-situ experiments.

The lander will softly land on the Moon and deploy the rover for in-situ chemical analysis. For lunar research, the lander and rover include scientific payloads.

Chandrayaan-3’s propulsion module?

The propulsion module propels the lander “from launch vehicle injection to the final 100 km circular polar orbit around the moon.” After the split, it will collect data for several months. The SHAPE payload will add value to the Propulsion Module after landing Module separation.

the ISRO payload will analyse “spectral and polarimetric measurements of Earth from lunar orbit.” “Future discoveries of smaller planets would allow probing into a variety of exoplanets that would qualify.

The next phases of Luna 25

The first modern Russian moon mission, Luna-25, began on August 10. The Russian spacecraft’s initial photographs were taken on Sunday (August 13).

“These photographs depict the device’s design against the Earth and moon backgrounds, showcasing our departure from Earth forever. Luna-25’s soft landing near the moon’s south pole in five to seven days is a major milestone.

The world awaits both missions’ crucial Moon composition, history, and resource findings.

The Moon’s south pole’s geology and water resources are intriguing. The relatively unknown region is vital for future lunar missions, including NASA’s Artemis-III effort to return humans to the Moon after five decades.

India or Russia would softly land on the Moon’s south pole first. The space race is crucial for exploration and becoming a worldwide space power.
