This is the final phase of Moon Landing.

23 Aug 2023, 17:53 IST

What comes after Rough Break Phase?

Once the Lander Module has reached a height of 7.5 kilometers from the lunar surface, the rough breaking phase will end. After that a 10 second period of Altitude Hold Phase will come where the propulsion will be adjusted to fix the orientation of the Lander as well as to do necessary course corrections. 

23 Aug 2023, 17:50 IST

ALS has taken over the landing

ALS or Autonomous Landing Sequence is a program that will control the entire landing process on its own. As a result, there will be no human intervention needed. From propulsion to sensors, everything is being handled by it. 

23 Aug 2023, 17:47 IST

Rough Breaking Phase has started

During this phase, the velocity of the Lander Module will be brought down from 1680 m/s to 358m/s. The altitude of the module will go from 30km to 7.4km to the surface of the Moon. In total, this phase will continue for a duration of 690 seconds (11.5 minutes).

ISRO chief says he's prepared for contingency

If all sensors fail, if everything fails it will still make a landing provided the propulsion system works well. This is how it has been designed. Even if two of the engines do not work also this time the lander will be able to land. It has been designed in such a way that it should be able to handle multiple failures. If the algorithms work well we should be able to do a vertical landing," ISRO chairman S. Somnath said.

Lunar touchdown looms as the nation watches

India is on the verge of a historic achievement as its third lunar mission, Chandrayaan-3, prepares for a soft and successful landing on the Moon's south polar region at approximately 6:04 pm today, August 23. In the event of adverse conditions, an ISRO scientist mentioned that the landing might be rescheduled to August 27. However, ISRO has expressed confidence that the lander will likely encounter no issues today. Report: India's Chandrayaan-3 Mission: Lunar touchdown looms as the nation watches

23 Aug 2023, 14:32 IST

Chandrayaan-3's different approach for success

In a press conference, ISRO chairperson S. Somnath said, “Instead of a success-based design in Chandrayaan-2, we are doing a failure-based design in Chandrayaan-3 —we are looking at what can go wrong and how to deal with it,” as quoted by the Indian Express.

The report by Indian Express has also delved into the changes that ISRO has implemented to avoid a similar fate as the previous lunar mission. This time ISRO has expanded the landing area and has chosen a spot with a 4 km x 2.4 km area, instead of a 500 sq meters area like the last time. The larger area is supposed to give the Chandrayaan-3 team more leeway in planning the landing.

More fuel has been added to the lander this time. This is likely to help it stay afloat longer and find alternative landing spots if need be. Additionally, this will also enable the lander to abandon the landing attempt if something goes wrong and try again after stabilizing its thrusters.

The delicate nature of the moon landing

Landing on the moon is no easy feat. The conditions are so harsh that even the slightest calculation error in figuring out the right time and path can lead to a failed mission. For instance, the Chandrayaan-3 lunar mission has been scheduled for 1 lunar day. One lunar day is 14 Earth days and this particular duration has been chosen since the rover cannot handle the extreme change in temperature once the lunar night rolls around. So, to ensure the rover has the right conditions, it will have to land precisely at lunar dawn.

Other factors such as payload weight, angle of detachment for the lander, speed at touch-down, and many more are considered in order to ensure a successful mission.

23 Aug 2023, 14:00 IST

What will Vikram Lander do after its landing?

After landing, the propulsion module will continue in its current orbit for months or even years. The Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload aboard the module will carry out a series of experiments, such as a spectroscopic study of the Earth's atmosphere, measurement of variations in polarization from the clouds on Earth, and collection of Exoplanet signatures that would qualify for our habitability.

What went wrong in the Chandrayaan-2 mission?

The Chandrayaan-2 mission began hitting all the right chords, but the problem arrived in the last phase of the mission when the lander and the rover were supposed to reach the lunar surface. On September 6, 2019, the lander deviated from its trajectory. According to reports, it was said to be a software glitch that increased the thrust on five of the engines on the lander and caused the crash.

23 Aug 2023, 13:30 IST

Why is a soft landing on Moon such a challenging thing?

The Russian Luna-25 mission met an unfortunate end when the spacecraft crashed on the lunar surface. Chandrayaan-2 also suffered a similar fate. The question is, why is a soft landing on Moon so difficult? 

Moon has a thin atmosphere and low pull of gravity. Both of these factors make it quite difficult to assess propulsion correctly to navigate to the surface. What makes it even more difficult is that the entire process is controlled remotely from the Earth while there is no conceivable way for the operators on Earth to correctly assess the situation.

Ex-ISRO chief Madhavan Nair warns of a crucial maneuver ahead of Moon landing

Ahead of the scheduled attempt at Moon landing, ex-ISRO chief Madhavan Nair has highlighted the crucial and complex maneuver the space agency will have to make in order to ensure a successful touchdown. Speaking to PTI, he said, “It's a very complex maneuver. We narrowly missed it (in the Chandrayaan-2 mission) in the last two kms. So there are a host of things that have to work in unison: thrusters, sensors, altimeters, computer software, and all those things. Any glitch happening anywhere...we can be in trouble”. 

23 Aug 2023, 12:30 IST

What is Chandrayaan-3 doing differently this time?

Learning from the mistakes, in a press conference, ISRO chairperson S. Somnath said, “Instead of a success-based design in Chandrayaan-2, we are doing a failure-based design in Chandrayaan-3 —we are looking at what can go wrong and how to deal with it".

23 Aug 2023, 12:14 IST

Goals of Chandrayaan-3 mission

Chandrayaan-3 has two main goals: First, to show that it can land safely and gently on the Moon, and second, to use a small rover for about 14 Earth days, which is equal to one lunar day. The rover is light, weighing only 26 kilograms. It will do scientific tests to learn about the Moon's origin, its rocks, and its composition, and analyze the environment.

Pragyan rover's journey after landing

The rover will get two weeks (one lunar cycle) to study the atmosphere of the Moon. The Pragyan rover is solar-powered and can only communicate with the Lander. Vikram Lander, on the other hand, can communicate with Earth directly and share all the data. As an emergency backup, the Chandrayaan-2 orbiter can also be used for communication.

23 Aug 2023, 10:43 IST

What happens after the lunar landing

If the Chandrayaan-3 mission is able to successfully land on the Moon, the Vikram Lander will open up on one side, creating a ramp for the Pragyan rover. Pragyan rover, which has the tricolor and ISRO logo on it, will move out of the lander after a period of 4 hours. Moving at a speed of 1 cm per second, it will use its navigation cameras to scan the surface of the Moon. Its main objective is to collect data on the composition structure of the Moon's atmosphere. On the other hand, Vikram Lander will also be collecting data on near-surface plasma, density, thermal properties, seismicity, and structural composition of the Moon's crust and mantle.

23 Aug 2023, 10:26 IST

Chandrayaan-3 components

The Chandrayaan-3 spacecraft has three components — a lander (Vikram), a rover (Pragyan), and a propulsion module. The lander and rover separated from the propulsion module on August 17 and commenced their descent toward the lunar surface. Meanwhile, the propulsion module will stay in orbit for months and years, and carry out its own series of experiments. Recently, the Lander Module (LM) of Chandrayaan-3 made contact with the orbiter or propulsion module of Chandrayaan-2, establishing two-way communication.
