PremiumChandrayaan-3 Highlights: Indian Space Research Organization (ISRO) will wait another 14 days to establish contact with Chandrayaan-3's Vikram lander and Pragyan rover. ISRO will continue attempts to revive the Chandrayaan-3 lander and rover till the next sunset on the Moon which is slated for October 6.
However, ISRO Chief S Somnath said that it is not certain when the contact with Chandrayaan-3 instruments will be established.
ISRO shared an update saying that it made efforts to establish communication with the Vikram lander and Pragyan rover to ascertain their wake-up condition, but as of now, no signals have been received from them. However, the space agency added that it would continue efforts to establish contact.
After a 40-day journey into space, the Chandrayaan-3 lander, 'Vikram', touched down on August 23 at the uncharted lunar South Pole making India the first country to do so. After transversing over 100 meters on the lunar surface from the Shiv Shakti Point, the touchdown spot of the lander Vikram on the lunar surface, the rover Pragyan was safely parked and set into sleep mode on September 2. Check all the latest updates here.
Former ISRO scientist Mayilsamy Annadurai and Padma Shri Awardee has said that Pragyan rover has good chances of revival. “I am pretty hopeful about Pragyan rover because it has been tested, but, with respect to Vikram lander, we will have to wait and see," he said as quoted by HT Tech.
Indian Space Research Organisation (ISRO) Chief S Somnath on Monday gave a special message and urged the people to participate in the Chandrayaan 3 Maha Quiz, on government site MyGov.in and celebrate the historic lunar landing.
In a video posted by ISRO on X, S Somnath says, "All of you know MyGov is a platform through which you are able to participate in the space quiz program. So don't forget to look at mygov.in. Log in and search for the space quiz program. Be a part of it. Support us, inspire us, get inspired."
Chandrayaan-3 is the follow-up mission of 2019's Chandrayaan-2 Mission which was partially successful as per the ISRO. In the previous Moon mission, the Vikram lander of the Chandrayaan-2 crashed while attempting the soft landing on the Moon's surface due to a technical glitch. However, this time scientists are optimistic about safe soft-landing as they have made certain changes in creating the Chandrayaan-3 spacecraft to avoid the same mistakes. Read more here.
As the Sun rises on the Moon for the next fifteen days, ISRO scientists are working day and night to revive the Chandrayaan-3's Vikram lander and Pragyan rover after a 15-day-long slumber. This will help in boosting the chances of extension over and above what has already been an entirely successfully complete mission.
Earlier, former ISRO scientist Tapan Mishra said that even if the rover fails to revive and the lander works, it will be a miracle. While speaking to ANI, he said, “Originally the Chandrayaan lander rover was designed for only 14 days of operation. It is expected that the temperature will go down to -140 degrees Celsius or lower, in the Southern pole it can reach down to -200 degrees Celsius. At this temperature, no plastic material, no carbon power material or no electronics can survive. They will crack. But I'm hopeful that ISRO must have done a lot of thermal management thing."

August 23: Vikram lander made a historic soft soft landing on the Moon's south pole.
August 24: Ch-3 Rover ramped down from the Lander and India took a walk on the moon
August 27: The first observations from the ChaSTE payload onboard Vikram Lander
August 28: LIBS confirms the presence of Sulphur (S) on the lunar surface through unambiguous in-situ measurements.
August 30: APXS on-board Ch-3 rover detects the presence of minor elements
August 31: ILSA listens to the movements around the landing site. RAMBHA-LP on-board Chandrayaan-3 measures near-surface plasma content
September 2 and 4: Both the lander and the rover were put into sleep mode earlier this month on September 4 and 2 respectively, ahead of the lunar night setting in on Earth's only natural satellite
September 22: Efforts to establish communication with lander and rover are underway.
After conducting experiments on the moon from August 23 to September 4, the rover and lander modules of Chandrayaan-3 were put to sleep in a bid to survive the extremely frigid atmosphere at the south pole of the moon.
"Vikram Lander and Pragyan Rover have been in deep sleep for almost two weeks now. It is almost like taking out something from the freezer and then trying to use it. The temperatures would have gone beyond -150 degrees Celsius," ISRO Chairman Madhavan Nair told ANI.
“The solar heat will warm up the instruments and also recharge the batteries. If both these conditions are successfully met, there is a fairly good chance that the system will be operational again."
Former ISRO scientist Tapan Mishra said that confirming the presence of water is the next important thing.
“There was a lesser induced spectroscopy instrument. It has shown us all the expected metals there. It has also shown us the presence of oxygen there, but we are looking for water. The oxygen can come from the breaking of any other silicon material which is actually the basis of all the rocks anywhere in the universe, also it can come from the breaking up of water. But if we could detect hydrogen there, detecting the presence of hydrogen would conclusively prove that there is water because hydrogen is never part of any other compound. So in that case we will be able to conclusively prove that there is water there. We have remote sensing-wise shown the presence of water. Now physically also we will able to show," he added.
The Vikram lander aboard Chandrayaan-3 lander touched down at the uncharted lunar South Pole on August 23 after a 40-day journey through space. The Pragyan Rover was safely parked and set into sleep mode on September 2 after transversing over 100 meters on the lunar surface from the Shiv Shakti Point.
“We had a plan to move the rover to almost 300-350 metres. But due to some reasons...the rover has moved 105 metres there," officials said on Friday.
ISRO said that it will continue to make attempts to establish contact with Chandrayaan-3's lander Vikram and rover Pragyan.

As the second phase of the Chandrayaan-3 lunar mission is about to begin with Pragyan Rover and Vikram lander awakening, Former ISRO Chairman K Sivan said, on "We have to wait and see. It has undergone a lunar night. Now the lunar day starts. So, now they will try to wake up. If all the systems are functioning, it will be alright...This is not the end, a lot more new Sciences will come. Even now the Chandrayaan-1's data has brought in a lot of discoveries. So, I hope that a lot of new things will come. Scientists will keep trying. So, this is not the end of the story..." (ANI)
As of now, Chandrayaan-3's lander is positioned at Shiv Shakti Point, awaiting the sunrise and reactivation. Before putting them to sleep, the lander and rover conducted experiments to explore the lunar atmosphere and surface properties for the intended 14 Earth days.
Ahead of the second phase of the Chandrayaan-3 lunar mission, former Indian Space Research Organisation ISRO chief K Sivan expressed optimism and said that the success of the wakeup call regarding the Vikram lander and Pragyan rover is something which "we have to wait and see".
Speaking to ANI on the second phase of the Chandrayaan-3 lunar mission, the Ex-ISRO chief said, "The success of the wake-up call is something we will have to wait and see. Now the lunar day starts soon, so they will try to wake up soon. All the systems are functioning, it will be alright."
Opposition MPs in the Lok Sabha on Thursday accused the BJP of politicising the success of the Chandrayaan-3 mission and said the government should increase budgetary allocation for promoting research and development in science and technology.
Congress MP Dean Kuriakose alleged that the BJP was politicising the success of the third moon mission by claiming that everything has been done after 2014. It was Jawaharlal Nehru who coined the term 'scientific temper' which is now used the world over, he claimed and demanded that there should be a mini science museum and science centre in all Lok Sabha constituencies.

The Vikram Lander and the Pragyan rover performed different set tasks on the lunar surface after landing. This included finding the presence of sulphur and recording relative temperature. Pragyan travelled over 100 m (330 feet), confirming the presence of sulphur, iron, oxygen and other elements on the moon.

As Indian Space Research Organisation (ISRO) preps to revive Chandrayaan-3's Vikram lander and rover from 'sleep mode' after almost two weeks, Nilesh M Desai, Director, Space Applications Centre (SAC) on Friday said that the 'revival' of the lander and the rover is "automatic" and cannot be nudged from the Earth.
The Director of the Space Applications Centre, one of the major centres of the Indian Space Research Organisation (ISRO), said that signals will come as soon as the solar-powered lander and rover are charged because of the sunrise, which happened in the lunar surface on September 22.
However, Desai said that till now no signals have come and that the efforts to establish contact with the Chandrayaan-3's lander Vikram and the rover Pragyan are underway. (ANI)
ISRO will wait till the next lunar sunset on October 6 in order to revive the Vikram lander and Pragyan rover of Chandrayaan-3.
“We don’t know when it will wake up. It could be tomorrow, or it could also be on the final day of the lunar day. But we are trying. It will be a great achievement if the lander and rover wake up," ISRO Chief S Somnath said on Saturday.

"As it is clear in ISRO's tweet, efforts are on to establish contact with the Lander and the Rover. It will automatically revive and send signals. Till now, no signals have come," the ISRO scientist told ANI.
Both the lander and the rover were put into sleep mode earlier this month on September 4 and 2 respectively, ahead of the lunar night setting in on Earth's only natural satellite. Desai said that on September 22, dawn broke on the moon and people would be informed once signals were recieved.
Observing a 50-50 per cent chance of the revival, the scientist further said that if the electronics survive the cold temperature we will recieve signals. "Otherwise, the mission has already done its job," he added.
The scientist added that if the lander and rover are revived, experiments on the moon's surface will continue.
Meanwhile, Padma Shri awardee and former ISRO scientist, Mylswamy Annadurai said, "...I am pretty hopeful about Pragyan because it has been tested...But, with respect to Lander, we will have to wait and see..." on ISRO's attempt to revive Vikram Lander and Pragyan Rover of Chandrayaan-3. (ANI)
If ISRO is able to revive the lander and the rover, the information that is derived from experiments that could once again be conducted by the Chandrayaan-3 payloads would be a "bonus". Former ISRO scientist Tapan Mishra said that confirming the presence of water would be the next important thing. Read more here
After putting the rover into sleep mode, ISRO had said, "The rover completed its assignments. It is now safely parked and set into sleep mode. APXS and LIBS payloads are turned off... Currently, the battery is fully charged. The solar panel is oriented to receive the light at the next sunrise expected on September 22, 2023." "The receiver is kept on. Hoping for a successful awakening for another set of assignments! Else, it will forever stay there as India's lunar ambassador," the country's space agency had said in a post on X.

“We had a plan to move the rover to almost 300-350 metres. But due to some reasons...the rover has moved 105 metres there," officials said on Friday.
Space scientist Suvendu Patnayak explained “The Chandrayaan-3 landed successfully and it worked for almost 14 days. It was designed to work for 14 days (on the moon). Its life period was only 14 days because the moon's temperature falls down to (-) 250 degrees during the (lunar) nighttime. So it worked during the sun hours or daytime and during that, it had already given all the data (it was supposed to)."
Patnayak recently superannuated as the deputy director of Pathani Samanta Planetarium in Bhubaneswar.
“It is very difficult for few electronic components to work in such a huge range of temperature. So it was expected it would not work after 14 days…But a few scientists are very hopeful that it may work again. So if it works again, it will be a boon for us and we will perform the same experiments again and again," Patnayak added
