Why Luna-25 is Faster than Chandrayaan-3

The race to the Moon’s south pole is heating up, with India and Russia both launching missions to the region in recent months. Luna-25, Russia’s first mission to the Moon in over 40 years, is expected to land on the south pole on August 21-23, while India’s Chandrayaan-3 is scheduled to land on August 23-24.
So why is Luna-25 expected to arrive at the Moon sooner than Chandrayaan-3? There are a few reasons:
Direct trajectory: Luna-25 is taking a more direct trajectory to the Moon, which will save time and fuel. Chandrayaan-3, on the other hand, is taking a more indirect route that will allow it to conduct more science experiments along the way.
Lighter payload: Luna-25 is much lighter than Chandrayaan-3, which means it requires less fuel to travel to the Moon. The lander weighs just 1,750 kilograms, while Chandrayaan-3 weighs 3,900 kilograms.
More efficient engines: Luna-25’s engines are more efficient than Chandrayaan-3’s engines, which will also help it to travel to the Moon faster.
In addition to these factors, Luna-25 also has the advantage of being launched from Russia’s Vostochny Cosmodrome, which is located closer to the equator than India’s Satish Dhawan Space Centre. This means that Luna-25 has a slight head start in terms of orbital velocity.
Of course, there are still a few days left before either mission lands on the Moon, so anything could happen. But as things stand, Luna-25 is the clear favorite to arrive at the Moon first.
What will Luna-25 and Chandrayaan-3 do on the Moon?
Both Luna-25 and Chandrayaan-3 are designed to study the Moon’s south pole, which is a region that has never been explored by humans or robots. The two missions will use a variety of instruments to study the lunar soil, exosphere, and geology. They will also look for signs of water ice, which could be a valuable resource for future human exploration.
Luna-25 will be the first Russian mission to the Moon since Luna-24 in 1976. It is a joint project between the Russian space agency Roscosmos and the European Space Agency (ESA). The lander will carry a variety of instruments, including a drill that will be used to collect samples of lunar soil.
Chandrayaan-3 is India’s third lunar mission. It is a follow-up to the Chandrayaan-1 and Chandrayaan-2 missions, which both orbited the Moon. Chandrayaan-3 will land a lander and rover on the south pole. The lander will carry a variety of instruments, including a spectrometer that will be used to study the composition of the lunar soil. The rover will be able to move around and explore the surrounding area.
Both Luna-25 and Chandrayaan-3 are important missions that will help us to learn more about the Moon. They are also a sign of the growing international interest in lunar exploration.
