Chandrayaan-5 to have heavier lander with longer mission life: ISRO Chief
Bengaluru (PTI): India is planning to collect samples from the Moon and bring them back to Earth under Chandrayaan-4, while Chandrayaan-5 will involve a heavier lander with a longer mission life, ISRO Chairman V Narayanan said on Wednesday.
He also spoke about ISRO's future missions including the one to study Venus and the other on Mars landing mission.
"Now we are working on the continuation of the Chandrayaan programme. In Chandrayaan-4, we plan to collect samples and bring them back. Chandrayaan-5 will involve a heavier lander with a longer mission life," he said at the inaugural ceremony of ISRO's fourth edition of the Space Science and Technology Awareness Training (START 2026) programme here.
He recalled that in Chandrayaan-3, the lander's mission life was only 14 days.
"In the future mission, we are talking about a life of around 100 days. The rover will also be heavier. Chandrayaan-3 had a rover of about 25 kg, while the future mission will have a rover of about 350 kg," Narayanan said.
Referring to ISRO's future programmes like the Venus Orbiter Mission, he said, "We have already accomplished the Mars Orbiter Mission, and now we are working on a Mars landing mission."
"These are some of the projects being discussed for government approval. So there is a lot of interest in the science area."
He noted that under Prime Minister Narendra Modi, the vision of the space programme has been expanded and said, "We are currently working on the Gaganyaan programme and are planning to send our own astronauts into space and bring them back safely, possibly within the next two years."
"We are also planning to build our own space station by 2035. Additionally, we are working on landing Indians on the Moon and bringing them back safely by 2040. Brainstorming activities have already begun. So there are many activities happening in the space sector. Apart from application-related activities that ensure food security, water security, communication, and safety for citizens, there are many initiatives planned in the science area as well," he added.
Narayanan noted that India's space programme has accomplished 10 scientific missions so far, including AstroSat, which recently completed a decade in orbit and was still functioning very well.
He also highlighted India's various lunar exploration missions -- Chandrayaan-1, Chandrayaan-2, and Chandrayaan-3 -- saying they led to many scientific discoveries.
"We are progressing in a big way," he added.
Highlighting the successful Chandrayaan-3 mission in the year 2023, the ISRO chairman said that India became the first country to successfully achieve a soft landing near the south pole of the Moon.
"Not only did we achieve the landing, but many discoveries were made. Around eight minerals were identified, seismic activity was studied, and the thermal profile of the Moon's surface was understood. Electron clouds were also studied. So many discoveries have come from that mission," he added.
Referring to the launch of Aditya-L1, the ISRO chairman said, "India is the fourth country to successfully place a satellite to study the Sun, and a large amount of data has already come out, and we have released the data as well."
Emphasising India's Space Vision 2047, he recalled that the country, which started with very humble beginnings, has developed significant capabilities.
"Today, we have the capability to conceive, design, and build our own launch vehicles, as well as conceive, build, and place satellites in orbit. Fifty years ago, we did not have this capability. Today, we can build satellites and the payloads required for them," Narayanan said.
Citing an example, he said that earlier optical cameras used lenses that were only about one inch in diameter.
"But today, in ISRO, cameras with optics of about 1.7 metres in diameter and almost one foot in thickness are being developed. These optics are being built at the LEOS (Laboratory For Electro Optics Systems) laboratory in Bengaluru for space observation. Many such activities are happening in the space sector," he noted.
He pointed out that the US, after 1969 and almost after 50-55 years, has again shown interest in landing on the Moon.
"The Artemis programme is already a very vibrant programme, with many activities going on. An accord was signed in 2023, and India is also a signatory to that accord," he said.
Speaking about China and Russia leading efforts to build the International Lunar Research Station (ILRS), the ISRO chairman noted, "When we talk about such space stations, one aspect is technology development. The second aspect is the large number of scientific experiments that will take place there. There is also a lot of competition today."
"There was a time when only government organisations across the world carried out space activities. Today, companies like SpaceX have advanced significantly. In fact, they have overtaken many others in terms of launches," he added.
He said that the main idea behind programmes like START 2026 is to encourage the next generation of youngsters to develop interest in this field and to build scientific temper so that they can become great leaders in building the nation.

LPG crisis: Karnataka temples gear up to stock wooden logs for ‘Prasada’
Bengaluru (PTI): Temples in Karnataka have started preparations to stock wooden logs fearing that the LPG shortage could hamper the ‘Prasada’ preparation and distributions to the devotees.
The looming LPG crisis in the state in the wake of Iran-Israel conflict has made the temple managements jittery.
According to the Akhila Karnataka Hindu Temple Archakas Federation (AKHTAF) president M S Venkatachalaiah, there is no immediate crisis in the temples.
“We have LPG cylinder stock that can last for a week but if this scarcity continues then there will be a problem in serving Prasada (offerings to the deity) to the devotees,” AKHTAF president said.
He added that many temples in the state have started stocking wooden logs to overcome the LPG crisis.
“Our temples have started preparing to store wooden logs to prepare Prasada though currently we don’t have a problem, at least for a week,” Venkatachalaiah told PTI.
Another priest working in a temple belonging to the state Endowment Department said the temples may have to go back to the traditional way of cooking as done in the ancient time using wood.
The LPG crisis has not affected the mid-day meal programme for government school students yet, though there was a meeting in the Education Department to find ways to tackle if crisis deepens, sources associated with the Mid-day Meal programme said.
Meanwhile, the largest partner of the Mid-day Meal programme in the country is Akshaya Patra.
The NGO said they do not depend much on LPG gas cylinder.
“The LPG crisis has not affected us. Our kitchens are steam-based, and we generate steam through boilers which run on electricity. That’s point number one. Point number two—gas is used only for very minor things, mainly for seasoning. That is the tadka,” an Akshaya Patra executive told PTI.
According to him, the NGO has has a gas reserves for about nearly one month across India, though gas is used in very small quantities every day.
He pointed out that the Mid-day meal programme will not be affected because in one or one-and-a-half weeks, schools will close owing to summer vacation.
Akshaya Patra feeds 23.5 lakh children across more than 24,000 schools across India, in 16 states and three Union Territories, he said.
