    Chandrayaan-3 live news: What are the lander and rover capable of?

    1. The lander has the capability to soft land at a specified lunar site and deploy the rover that will carry out in-situ chemical analysis of the moon's surface during the course of its mobility.
    2. The lander and the rover have scientific payloads to carry out experiments on the lunar surface.

    Chandrayaan-3 live news: Where would India's rank be if ‘Vikram’ lands successfully on Moon

    If the Chandrayaan-3 mission succeeds in landing a robotic lunar rover in ISRO's second attempt in four years, India will become the fourth country to master the technology of soft-landing on the moon's surface after the US, China and the former Soviet Union.

    The race to the uncharted south pole of the Moon is also hotting up with Russia's Luna-25 also gearing up for lunar landings next week. The proximity, possible overlap, of their landing dates -- August 21-23 for Luna-25 and August 23-24 for Chandrayaan-3 -- has heightened excitement in the scientific community worldwide.

    Chandrayaan-3 live news: Next action before landing on lunar surface

    After Thursday's separation, the lander is expected to undergo a "deboost" (the process of slowing down) to place it in an orbit, where the Perilune (the orbit's closest point to the Moon) is 30 kilometres and Apolune (farthest point from the Moon) is 100 km, from where the soft landing on the south polar region of the Moon will be attempted, ISRO sources said.

    Meanwhile, the Propulsion Module will continue its journey in the current orbit for months/years, the country's space agency said.

    Chandrayaan-3 live news: What is the between India and Russia

    Luna-25's launch on August 11 was facilitated by a robust Soyuz-2 Fregat booster, while ISRO selected the Launch Vehicle Mark-III for the Chandrayaan-3 mission launched on July 14.

    Notably, Luna-25 benefits from excess fuel storage, eliminating concerns about fuel efficiency. This advantage allows Luna-25 to pursue a more direct trajectory, Dr K Sivan, former ISRO chairperson told to PTI. In contrast, Chandrayaan-3's limited fuel-carrying capacity necessitated a more circuitous route to reach the Moon.

    Furthermore, Luna-25 boasts a leaner lift-off mass of 1,750 kilograms, significantly lighter than Chandrayaan-3's 3,800 kilograms. This reduced mass empowers Luna-25 to achieve acceleration more efficiently.

    Chandrayaan-3 live news: What did ISRO chief say about Moon landing?

    1. ISRO Chairman S Somanath had recently said the most critical part of the landing is the process of bringing the velocity of the lander from 30 km height to the final landing
    2. The ability to transfer the spacecraft from horizontal to vertical direction is the "trick we have to play" here. 
    3. "The velocity at the starting of the landing process is almost 1.68 km per second, but this speed is horizontal to the surface of the moon. The Chandrayaan-3 here is tilted almost 90 degrees, it has to become vertical. So, this whole process of turning from horizontal to vertical is a very interesting calculation mathematically. We have done a lot of simulations. It is here where we had the problem last time (Chandrayaan-2)," Somanath explained.

    Chandrayaan-3 news live: What went wrong with Chandrayaan-2?

    The Chandrayaan-2 mission faced a setback on September 7, 2019, when the Vikram lander deviated from its intended path during the landing attempt, resulting in a loss of communication with the lander carrying the Pragyan rover.

    Despite this unforeseen outcome, the orbiter component of Chandrayaan-2 remains operational, orbiting the moon and gathering valuable scientific information. This mission marks a significant milestone in India's space exploration endeavours.

    Chandrayaan-3 and Russia’s Luna-25: race to Moon's south pole heats up

    The race to the uncharted south pole of the Moon is quickening with India’s Chandrayaan-3 and Russia's Luna-25 gearing up for lunar landings next week, each mission holding significant implications beyond the thrilling competition in the skies.

    While Chandrayaan-3 plans to be the first to land on the Moon's south pole, Luna-25's swift trajectory has cast new light, say experts as anticipation builds up. The proximity, possible overlap, of their landing dates -- August 21-23 for Luna-25 and August 23-24 for Chandrayaan-3 -- has intensified global scrutiny.

    Chandrayaan-3 or Russia's Luna 25: Which lander will touch the Lunar surface first?

    Roscosmos stated that its Luna 25 spacecraft will take about five days to travel to the Moon. It will then spend around five to seven days in lunar orbit before descending to one of three potential landing sites near the pole, reported Reuters.

    This timeline indicates that Russia's mission could reach the lunar surface around the same time as or shortly before the Indian mission.

    Roscosmos, however, assured that the two missions won't interfere with each other, as they have separate landing areas planned. The Russian Space Agency stated, “There is no danger that they interfere with each other or collide. There is enough space for everyone on the moon,” Reuters added.
