<p>It was a Saturday Science Thriller like no other! The&nbsp;much-anticipated ISRO rocket launch that was originally scheduled for 8:00 am, was rescheduled twice within an hour (to 8:30 and 8:45). At 8:45 am, as people and journalists at the spaceport looked skywards, the vehicle did not lift off. As the countdown timer was at minus five seconds, the computer had put the launch on hold, owing to an anomaly in engine ignition.&nbsp;Videos from the launchpad showed the rocket emitting red fumes, indicating that it was just moments away from launch. The ISRO Chief had acknowledged the anomaly and said that their team would identify the fault and schedule the launch after the fault was rectified. When most people lost hope, ISRO had silently rectified the issue within an hour and launched at 10 am sharp.&nbsp;</p>

<p>After the setback on the launchpad, ISRO Chief Dr S. Somanath said, "The lift-off attempt of TV-D1 could not happen today...We had a very smooth Automatic Launch Sequence leading up to the command to lift off the engine...But the engine ignition has not happened in the nominal course, we have to find out what went wrong with that. The entire vehicle is safe." While it seemed that the launch would happen only weeks later, ISRO was quick to rectify the issue with their computer systems and resume the countdown.</p>

<p>A few seconds after the clock struck 10:00 am, amid hazy skies, the only indication of the Test Vehicle having lifted off was the loud rumble of the liquid-fuelled Vikas engine that powers the Test Vehicle. Soon after, the flight events happened precisely in the planned sequence.&nbsp;As per the plan, 61 seconds from lift-off, the vehicle reached an altitude of 11.9km&nbsp;and a speed of Mach1.2 (1480kmph) and that's when the rocket shut down, as pre-programmed. Immediately, the Crew escape system triggered and the top portion of the rocket comprising the escape system and the crew module ejected itself higher and farther away from the rocket. They travelled a couple of kilometres higher away from the rocket. 90 seconds after lift-off, at around 17km&nbsp;altitude, the crew escape system and crew module separated. While the rocket and the crew escape system rapidly fell into the sea, the crew module used multiple parachutes to gradually descend and splash down, almost 10 km away from the spaceport's shore. From lift-off to splashdown, this mission took place in nine minutes, and the ISRO Mission Control broke into a celebration as the parachutes deployed during the crew module descent.</p>

<p>In his post-mission address, ISRO Chief Dr. S. Somanath said, 'TV-D1' fully accomplished its objectives. "Crew module has safely landed. I'm very happy to announce a successful mission accomplishment. The crew module has splashed down at the required velocity and this confirmation data has been received. The recovery activity will continue to happen" he added.&nbsp;</p>

<p>Explaining the delay, the anomaly and the suspense, Somanath said that the initial delay was owing to weather-related issues. "Thereafter, the computer detected an anomaly in the rocket and put the launch on hold, with barely 5 seconds to go for lift-off. "We understood that the non-conformance(error detected) was due to a monitoring anomaly in the system. We identified and rectified it very fast and took our time to refill the gases in the rocket and again went for the launch" he elaborated. Referring to the process of rapidly identifying and rectifying the anomaly, Somanath said that it was training for the team, in preparation for the Gaganyaan astronaut mission.&nbsp;</p>

<p>According to 'TV-D1' Mission Director Sivakumar, the three components in this test - Test Vehicle rocket, Crew Escape System and Crew Module had performed perfectly in their maiden attempt. The ISRO Chief said that more data from this mission would be available, once the crew module is recovered and handed over to ISRO at the Chennai Port. WION had first reported that two Indian ships INS Shakti and SCI Saraswati would be waiting at a safe distance to recover the empty capsule. INS Shakti is a fleet tanker of the Indian Navy and SCI Saraswati is a multi-purpose support vessel (meant to supply offshore installations and serve research purposes) of the Shipping Corporation of India. Notably, both these vessels are capable of having helicopters on board, thereby acting as a force multiplier and offering airborne assistance to their respective primary missions.&nbsp;Visuals beamed to ISRO, from aerial assets showcased the crew module recovery activity at sea. The activity involved multiple large vessels and smaller crafts.</p>

ISRO delivers a Saturday Space Science Thriller, Gaganyaan maiden test flight 'TV-D1' successful

<p><meta name="uuid" content="uuidPwxfue4YP6cq" /><meta charset="utf-8" /></p>

<p>Mahendra Singh Dhoni was one of the several excited citizens who waited to witness Chandrayaan-3's successful landing on Earth's Moon. On Wednesday, Mahendra Singh Dhoni had his eyes glued to the television like millions of other Indians.&nbsp;</p>

<p>When the historic moment arrived at 06:04 pm IST, Dhoni reacted in a typical nonchalant fashion. India's former captain is famous for his calm and composed demeanour, on and off the cricket pitch. While others around him applauded, the cricketing legend clapped on his thighs. He was wearing a tank t-shirt and shorts. However, his reserved reaction does not imply a lack of enthusiasm. Anyone who knows MS Dhoni will understand that his behaviour during the most grand victories is serene.&nbsp;</p>

<p>Many celebrities have reacted to the successful landing of Chandrayaan-3 on social media. However, Mahendra Singh Dhoni is not very active on any such platform. Here's a video of him watching the iconic event.</p>
