Chandrayaan-3: Live broadcast of Chandrayaan-3 moon landing will be shown in many schools in India

Read About Chandrayaan-2

The much-awaited landing of the third edition of India’s lunar mission series is less than 48 hours away. The Indian Space Research Organization (ISRO) has also announced that it plans to telecast the event live starting at 5.20 pm that day. At the same time, the government has issued an order to show the live telecast of Chandrayaan-3 landing on the moon in all the schools of the state.

Lending attempt for Chandrayaan-3

India attempted to land the lander on the Moon in the year 2019 under the Chandrayaan-2 mission. However, just before it crashed, communication with the lander was lost. This time ISRO has taken many extra precautions for successful landing.These include failure-based design rather than success-based design. ISRO chief Somnath has said that instead of success-based design in Chandrayaan-2, ISRO chose failure-based design in Chandrayaan-3 (Chandrayaan-3 Live), focusing on what could fail and how to keep it safe and ensure a successful landing.

Somnath said, “We looked at a lot of failures – sensor failure, engine failure, algorithm failure, calculation failure. So, whatever the failure is we want it to be fixed. So different failure scenarios are calculated and programmed The most critical part of the landing is the process of reducing the velocity of the lander to a soft landing on the Moon from an altitude of 30 km.We have to shift it from horizontal to vertical direction. The velocity at the beginning of the landing process is approximately 1.68 km per second, but this velocity is horizontal to the lunar surface.

Chandrayaan-3

Chandrayaan-3 is tilted almost 90 degrees here, it has to be made vertical. That’s why the process of changing from horizontal to vertical is important. We have done a lot of simulations. This is where we had a problem last time (Chandrayaan-2). This time many technical changes have been made for the successful landing of Chandrayaan-3. With this the area of ​​the landing spot has been increased. At the time of Chandrayaan-2, the landing site was small. Solar panels have also been increased.

Orbiter of Chandrayaan-2 will help in successful landing

Astronomer Priya Hasan said that Chandrayaan-2’s rover will help in soft landing of Chandrayaan-3’s landing module (lander and rover). The orbiter accompanied Chandrayaan-2, which is still circling around the Moon, he said. In a soft landing, the lander descends at a very high speed of about 6,000 kmph, he said.

Suddenly it has to apply brakes and make a landing on the surface. We know that the surface is full of potholes. For this precautions were also taken in Chandrayaan-2. But it didn’t work. Now we have the good advantage that the orbiter is operational since 2019. The orbiter has mapped the entire surface of the Moon very well.We haven’t had such accurate maps of the Moon before. Thanks to Chandrayaan-2, we now have such accurate maps of the Moon. There is no orbiter in Chandrayaan-3 as Chandrayaan-2 orbiter is still working. The lander of the Chandrayaan-3 mission has been named after Vikram Sarabhai, who is considered the father of the Indian space programme.

Live Streaming

It will be telecast live on ISRO’s website isro.gov.in and ISRO’s official YouTube channel as well as on DD National. For this, instructions have been given to make arrangements for projector and TV etc.

Meanwhile, news agency ANI quoted a senior ISRO scientist as saying on Monday that if any factor appears to be unfavourable, we will postpone the landing of the module on the Moon till August 27.

Successfully lending

The Chandrayaan-3 mission has made history by successfully landing on the moon’s south pole, an area that has not before been studied but is expected to be rich in water ice.
