Taking to X (formerly Twitter), ISRO said, "Chandrayaan-3 Mission. Chandrayaan-3 Rover to MOX, ISTRAC, Moon walk begins!"
The 'top leadership' of the National Testing Agency is under the scanner over alleged irregularities in competitive exams National Eligibility-cum-Entrance Test and National Eligibility Test, Union Education Minister Dharmendra Pradhan said on Saturday even as he denied any paper leak in the Council of Scientific and Industrial Research-University Grants Commission NET, which was postponed a day ago.
The lessons learned from the failure of Chandrayaan-2 contributed to the success of India's third lunar mission, former space scientist with the Indian Space Research Organisation (ISRO) Nambi Narayanan said, after the successful touchdown of the 'Vikram' lander on the lunar South Pole.
Chandrayaan-3 is now in an orbit, which when closest to Earth is at 173 km and farthest from Earth is at 41,762 km, the space agency said.
After Chandrayaan-3 touched down on the Moon, the Congress on Wednesday said it is a collective success of every Indian and ISRO's achievement reflects a saga of continuity and is truly fantastic.
This camera that assists in locating a safe landing area -- without boulders or deep trenches -- during the descent is developed by Ahmedabad-based Space Applications Centre (SAC), a major research and development centre of ISRO.
ISRO has to select astronauts, training them to withstand the space environment, and then bring them back to earth and rehabilitate them.
Former National Aeronautics and Space Administration (NASA) Official Mike Gold has said Chandrayaan-3's success is a triumph of Indian innovation, human capital and the capabilities that will take India even further.
India's ambitious third Moon mission's spacecraft Chandrayaan-3 after the launch on July 14, had entered into lunar orbit or the Moon's orbit on August 5.
Aditya-L1 is the first Indian space-based observatory that will study the Sun from a halo orbit around the first Sun-Earth Lagrangian point (L1), which is located roughly 1.5 million km from the Earth.
Connecting with people is the first step to creating greater awareness for the brand and that in turn, believes ISRO chief K Sivan, will translate into the institution becoming a place that people want to work in.
Only three countries (United States, Russia and China) have successfully landed spacecraft on the airless lunar surface.
Here is a glimpse of the journey of India's third lunar exploration venture has taken so far.
Modi gave these directions during a meeting to review the preparedness of the Gaganyaan mission and the first demonstration flight of the crew escape system test vehicle scheduled for October 21.
The Luna-25 spacecraft crashed into the Moon after it spun into an uncontrolled orbit, Russia's Roscosmos space agency said on August 20.
Antrix, ISRO's commercial arm, is eyeing 10% of the $357 billion global market.
The mission objectives of Chandrayaan-3 are to demonstrate a safe and soft landing on the lunar surface, to demonstrate rover roving on the Moon, and to conduct in-situ scientific experiments.
An ISRO official said: "Unless and until everything is intact (lander), it's very difficult (to re-establish contact). Chances are less. Only if it had soft-landing, and if all systems functioned, then only communication can be restored. Things are bleak as of now."
This would be the 44th flight of the PSLV and the third launch by ISRO this year.
The Centre on Saturday night announced that the probe into alleged irregularities in the medical entrance exam NEET will be handed over to the CBI for a comprehensive investigation.
Here is ISRO's SAC Director, Nilesh M Desai explains the crucial stage of soft landing.
'When a Project Director is appointed, the whole organization -- including the Chairman ISRO -- works for his success. It is a lesson that has been of abiding value all through the other projects I have worked on,' recalls the late President, one of the earliest pioneers at ISRO.
So, if ISRO is able to revive them as the Sun rises on the Moon again, information that is derived from experiments that could once again be conducted by the Chandrayaan-3 payloads would be a "bonus".
The launch is tentatively scheduled at 09.28 hrs IST on November 25, 2019 subject to weather conditions, ISRO said.
According to the space agency, Chandra's Surface Thermophysical Experiment measured the temperature profile of the lunar topsoil around the south pole, to understand the thermal behaviour of the Moon's surface.
The ISRO had apparently suspended those operations 10 days ago following night fall on the Moon.
The five-day course aims to raise awareness among students on remote sensing technology and its use for the study of planet earth and its environment.
Microsat-R, an imaging satellite, is meant for military purposes, but the ISRO did not give any details about it.
The earth observation satellite would provide real-time images of the country and also be able to quickly monitor natural disasters.
The soft landing of the spacecraft is planned for late August. The mission is expected to be supportive to future interplanetary missions.
The space agency had got support from the entire nation, despite it losing communication with the lander ahead of the touchdown, with people from all walks of life praising ISRO and its scientists for the achievement.
The 436-kg EMISAT and other satellites would be launched from the Satish Dhawan Space Centre in Sriharikota.
The Chandrayaan-2 will conduct the next level of scientific studies on the Moon, writes T E Narasimhan.
Data collected around L1 would provide insights into the origin, acceleration, and anisotropy of solar wind and space weather phenomena, it said.
Despite the chill in bilateral ties, Pakistan's media on Thursday gave front-page coverage to India's historic moon landing while a former minister even called it a 'great moment' for Indian Space Research Organisation.
The video showed the Moon in bluish green colour with many craters.
ISRO has said once the Lunar night falls, there would be no sunlight for the lander to generate power for its working and also it was not designed to operate in the heavy cold temperature of Moon during the phase.
