'A solid motor, once ignited, burns until the propellant is exhausted. It cannot simply stop mid-burn,' said a retired senior ISRO official. 'That is what makes this failure puzzling.' Venkatachari Jagannathan reports on the latest PSLV failure.
Prime Minister Narendra Modi was accorded a warm reception as he arrived at the Indian Space Research Organisation headquarters in Bengaluru on Saturday morning.

The Indian Space Research Organisation is gearing up to turn on several probes, a day after the box carrying the Moon Impact Probe, armed with the tricolour, crash-landed on the lunar surface to mark India's presence on the moon.Scientists at ISRO told rediff.com that the groundwork to detach eight other payloads from Chandrayaan-1, in order to conduct further studies on the moon, was underway.
Chandrayaan-3 mission's lander 'Vikram' chose a relatively flat region on the lunar surface to touch down, images captured by its camera showed.
India is now on the Moon and the success of the lunar mission has sounded the bugle for the emergence of a developed nation, Prime Minister Narendra Modi said on Wednesday as Chandrayaan-3 landed successfully on the lunar surface.
The Indian Space Research Organisation said it successfully carried out an "extremely challenging" controlled re-entry experiment of the decommissioned orbiting Megha-Tropiques-1 (MT-1) satellite.
The ISRO had said it would attempt softlanding on the lunar surface on August 23.
Skyroot Aerospace has become the first private company in India to give wings to the Indian space programme, after the sector was opened to private players by the Centre in 2020.
A visibly emotional Modi addressed scientists at the Indian Space Research organisation's command centre in Bengaluru, who were involved in the Chandrayaan-3 mission and lauded them for their efforts.
August 23, the day the Chandrayaan-3 lander touched down on the lunar surface, would be celebrated as 'National Space Day'.
"Progressively, you can imagine that it becomes that much more difficult, with each passing hour, the available power on the battery gets drained out, and there won't be anything left for it to power and operate", an ISRO official said.
The test vehicle development flight (TV-D1) is aimed at testing the crew module that will carry Indian astronauts during the human spaceflight late next year.
All spacecraft parameters are normal, the Bengaluru headquartered space agency said after the maneuver on the spacecraft.
Crossing a major milestone in the country's space history, ISRO's Mars Orbiter mission ventured out of Earth's sphere of influence for the first time in an attempt to reach the red planet's orbit
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."
As scientists at the Indian Space Research Organisation (ISRO) gear up for the much-awaited soft landing of the Chandrayaan-3 spacecraft on the Moon's surface, the space agency may postpone the touchdown to August 27 in the event that health parameters of the lander module are found to be "abnormal", a senior official has said.
About 80 per cent of Indians have a favourable view of Prime Minister Narendra Modi and around seven in 10 Indians believe their country has recently become more influential, according to a survey by the PEW Research Center.
'Today onwards, the onboard thrusters will be fired and Chandryaan-3 will be taken away from Earth for an eventful landing on Moon's surface on August 23'
Indian Space Research Organisation's plan to soft land Chandrayaan-2's Vikram module on the Lunar surface did not go as per script in the early hours of Saturday, with the lander losing communication with ground stations during its final descent.
'I am extremely excited to be at the ISRO Centre in Bengaluru to witness the extraordinary moment in the history of India's space programme,' Modi tweeted earlier in the day.
Hours before Chandrayaan-2's 'Vikram' module's proposed soft landing on the Lunar surface, Indian Space Research Organisation chairman K Sivan said on Friday things are progressing as per plan for the much-awaited event.
India became the fourth country to make its mark on the moon when Chandrayaan-I's MIP landed on the moon's surface on Friday, at approximately 8.30 pm IST.The MIP, proudly bearing the Indian tricolour, crash landed on the moon's surface after being detached by Chandrayaan-1.The Indian Space Research Organisation's command room has confirmed that it has received its first signal from the MIP.
'We hope one of these days we will get a message that can make us feel very relieved,' Krishna said.
Even as the scientists and staff at Mission Operations Complex broke into applause, the core team members thanked all those who had worked on the mission. Quietly and without jingoistic boasting of their stupendous achievement. And that is the most remarkable aspect of ISRO -- they let their work do the talking, notes Minnie Vaid, author of Those Magnificent Women And Their Flying Machines, ISRO's Mission to Mars.
Nirmala Sitharaman, Amit Shah, Arvind Kejriwal and Rahul Gandhi also expressed solidarity with ISRO.
The ISRO is aiming for a soft landing of the lander in the South Pole region of the moon where no country has gone so far.
Two de-orbit manoeuvres of Vikram Lander, to bring it further down, have been planned to prepare for its landing in the south polar region of the moon.
