New Delhi [India], July 13 (ANI): <keyword id="8011274" type="General" weightage="20" keywordseo="chandrayaan-3" source="Orion">Chandrayaan-3</keyword>, India's third lunar exploration mission, will make India the fourth country to land its spacecraft on the surface of the moon and demonstrate the country's abilities for safe and soft landing on lunar surface. The countdown for the launch of the mission began on Thursday at 14:35:17 IST ahead of take-off on Friday from the Satish Dhawan Space Centre in Sriharikota. The spacecraft will be launched on a GSLV Mark 3 (LVM 3) heavy-lift launch vehicle. This will be Indian Space Research Organisation's (ISRO) follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing in 2019. The 'Launch Rehearsal' simulating the entire launch preparation and process has been concluded by the ISRO. A day ahead of the Chandrayaan-3 mission, a team of ISRO scientists on Thursday visited and offered prayers at Tirupathi Venkatachalapathy Temple in Andhra Pradesh with a miniature model of Chandrayaan-3. If all goes well, Chandrayaan-3 will be the first spacecraft to land on Moon's South Pole, demonstrating India's technical prowess and bold spacefaring ambitions. Chandrayaan-3 mission will demonstrate a safe and soft landing on the lunar surface, rover roving on the moon and conducting in-situ scientific experiments. ISRO invited citizens to witness the launch of the much-awaited Chandrayaan-3 from the viewing gallery at Sriharikota. During the Chandrayaan-2 mission, ISRO lost contact with the lander when it was just a notch away from the moon's surface. The journey from Earth to the moon for the to-be-launched spacecraft is estimated to take around a month and the landing is expected on August 23. Upon landing, it will operate for one lunar day, which is approximately 14 Earth days. One day on Moon is equal to 14 days on Earth. K Sivan, former director of ISRO, told that the success of mission Chandrayan-3 will give a morale boost to programs like Gaganyan. "We understood what went wrong with Chandrayan-2 when we could not land on the moon's surface, we recreated the failure modes and we ensured that this time we have success. The challenge is the same as Chandrayan-2, same environment for landing. This time we hope that we have done enough based on the lesson of Chandrayan-2 that gives us more confidence. In space there are always unknown unknowns...hope that all issues are addressed and that we emerge with success," he said. "We are getting tech landing on a celestial body. By landing successfully, we will acquire landing technology and it will be good for future generations. A number of scientific experiments are planned and scientists will have more knowledge of the moon's geology and the earth's origin," he added. Mylswamy Annadurai, Mission Director of Chandrayaan-1, said Chandrayaan-3 is a very important mission. "We have shown that we can orbit, but we could not do a soft landing, By doing so this time we can show that Chandrayan-1 was not an isolated success. Internationally, the world is looking back to the moon, the real seeding for that came from Chandrayaan-1. So we need to make this mission successful," he told ANI. "Hard lessons were learnt from Chandrayaan 1 and 2. At every step, we are supposed to have a plan B. There were some setbacks in Chandrayaan- 2. This time we are back on track. We are clear on what we want to do and it will ensure we can softly land on the surface of the moon. The target of landing is also larger, all elements have been tested multiple times, we hope this is a success...," he added. Chandrayaan-3's development phase commenced in January 2020 with plans to launch it somewhere in 2021, but the COVID-19 pandemic caused delays in the development process. The major discovery of the Chandrayaan-1 mission, launched in 2008, is the detection of water (H2O) and hydroxyl (OH) on the lunar surface. Data also revealed their enhanced abundance towards the polar region. The primary science objective of the mission was to prepare a three-dimensional atlas of both the near and far sides of the Moon and to conduct chemical and mineralogical mapping of the entire lunar surface with high spatial resolution, Vikram Sarabhai Space Centre under ISRO had said. Moon serves as a repository of earth's past and a successful lunar mission by India will help in enhancing life on Earth and prepare to explore the rest of the solar system - and beyond. Director of Indian Space and Research Organisation (ISRO), S Somanath, had said that if everything goes well, the spacecraft will land on the moon on August 23. The date has been decided based on sunrise on the moon but if it gets delayed, then landing may take place next month, he said. (ANI)

The GSLV Mark 3 (LVM 3) heavy-lift launch vehicle, which will release the moon <keyword id="1609912" type="General" weightage="20" keywordseo="lander" source="Orion">lander</keyword> and rover into space, will lift off from Satish Dhawan Space Centre in Andhra Pradesh's Sriharikota at 2.30 pm. The countdown for the launch began on Thursday at 14:35:17 IST, ahead of the lift-off on Friday. Chandrayaan-3 will be ISRO's follow-up attempt after the <keyword id="229677" type="General" weightage="20" keywordseo="chandrayaan-2-mission" source="Orion">Chandrayaan-2 mission</keyword> faced challenges during its <keyword id="943223" type="General" weightage="20" keywordseo="soft-landing" source="Orion">soft landing</keyword> on the lunar surface in 2019 and was eventually deemed to have failed its mission objectives. The 'Launch Rehearsal' simulating the entire launch preparation and process was concluded earlier by the ISRO. Chandrayaan-3 is equipped with a lander, <keyword id="18004591" type="General" weightage="20" keywordseo="a-rover-and-a-propulsion-module" source="Orion">a rover and a propulsion module</keyword>. It weighs around 3,900 kilograms. The ISRO's third lunar exploration mission is equipped with eight payloads. The experiments to be carried out by Chandrayan 3 include the Vikram lander (named after Space scientist Vikram Sarabhai) which will carry 4 instruments, Pragyan (Saanskrit for Wisdom) rover will carry two instruments and Propulsion Module or the Orbiter will carry one experiment. Vikram lander's experiments include Chandra's Surface Thermophysical Experiment (ChaSTE) to measure surface thermal properties, Instrument for Lunar Seismic Activity (ILSA) to measure seismicity around the landing site, Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) to study the gas and plasma environment, and Passive laser retroreflector array provided by NASA for lunar ranging studies. While the Pragyan (Saanskrit for Wisdom) rover will carry two instruments to study the surface elemental composition - Alpha Particle X-ray Spectrometer (APXS) that will help determine the elemental composition of the lunar soil and rocks around the landing site and Laser Induced Breakdown Spectroscope (LIBS) which will conduct qualitative and quantitative elemental analysis in order to infer the chemical and mineralogical composition of the lunar surface. The Propulsion Module or the Orbiter will carry Spectropolarimetry of Habitable Planet Earth (SHAPE) to study Earth's spectral and polarimetric measurements from lunar orbit. This helps scientists analyse the reflected light from exoplanets and determine whether they would qualify for habitability. The journey from Earth to the moon for the spacecraft is estimated to take about a month and the landing is expected on August 23. Upon landing, it will operate for one lunar day, which is approximately 14 Earth days. One day on the Moon is equal to 14 days on Earth. K Sivan, former director of ISRO, told that the success of mission Chandrayan-3 will give a morale boost to programmes like Gaganyan, India's first manned space mission. Chandrayaan-3's development phase commenced in January 2020 with the launch planned sometime in 2021, but the Covid-19 pandemic brought an unforeseen delay to the mission's progress. The major discovery of the Chandrayaan-1 mission, launched in 2008, was the detection of water (H2O) and hydroxyl (OH) on the lunar surface. Data mined by the rover then also revealed their enhanced abundance towards the polar region.

The space agency has planned for the launch of CARTOSAT-3 satellite, ninth in the series, from the second launch pad at spaceport of Sriharikota, about 120kms from here on November 27 at 09.28 am. "26 hours countdown for the launch of PSLV-C47 mission commenced today at 0728hrs from SDSC SHAR, Sriharikota. Launch is scheduled at 0928 hrs IST on November 27, 2019," ISRO said in its update on Tuesday. PSLV-C47 on its 49th mission would carry CARTOSAT-3 along with 13 commercial nano satellites from the United States. CARTOSAT-3 is a third generation agile advanced satellite having high resolution imaging capability. With an overall mass of 1,625kgs, CARTOSAT-3 would address the increased user's demands for the large scale urban planning, rural resource and infrastructure development, coastal land use and land cover. PSLV-C47 is the 21st flight of PSLV in the 'XL' configuration (with six solid strap-on motors), ISRO said. The 13 commercial nano satellites from the United States are being carried as part of the commercial arrangement with NewSpace India Ltd (NSIL), Department of Space. Among the 13 nano-satellites are FLOCK-4P, 12 in numbers, with mission objective of earth observation, and one satellite named MESHBED, whose mission objective is communication test bed. ISRO said Wednesday's launch would be the 74th launch vehicle mission from <keyword id="6356967" type="COMPANY" weightage="20" keywordseo="satish-dhawan-space-centre">Satish Dhawan Space Centre</keyword>, Sriharikota. The mission life of CARTOSAT-3 would be for five years. The launch of CARTOSAT-3 and 13 other commercial nano satellites follows ISRO's moon mission <keyword id="53289" type="PERSON" weightage="20" keywordseo="Chandrayaan-2">Chandrayaan-2</keyword> on July 22, which failed to manage a soft landing on the moon, and would have been the country's first had it been successful.

And, it’s only the beginning. The agency has its ‘hands full’ until March with 13 planned launches, according to the chairman, K Sivan. "We are having 13 mission up till March. These 13 missions comprise of 6 large vehicle missions and 7 satellite missions… Our hands are full," he said at the post-launch press conference. A new rocket in the works The Small Satellite Launch Vehicle (SSLV) is a new design by ISRO which is expected to conduct its <a href="https://www.businessinsider.in/isros-new-company-just-made-its-first-sale-to-an-american-firm-to-come-aboard-a-rocket-that-doesnt-exist-yet/articleshow/70588829.cms">maiden flight</a> in January. The rocket is based on the design of another ISRO rocket, the Polar Satellite Launch Vehicle (PSLV) but the final changes are yet to be unveiled. Since it’s a smaller rocket it can only carry 500 kilograms, but its main selling point isn’t its capacity — but the time it takes to get ready. According to ISRO, it will only take three days to prepare for an SSLV launch as compared to the months it takes to prepare for launches using other rockets. "The small satellite ecosystem is expanding at an accelerated pace," according to ResearchAndMarkets <a href="https://www.prnewswire.com/news-releases/global-small-satellite-launch-services-market-h1-2019---2033---growing-demand-for-launch-and-the-onset-of-scheduled-dedicated-launch-services-300964484.html">report</a>. India is one of the players in the market that sees the demand for more rideshare capacity. It plans to meet the upcoming demand by providing dedicated services and launch flexibility. Even though the details of the rocket haven’t been officially disclosed, it has already landed its first customer — Spaceflight. The company bought a payload aboard the SSLV in August. Sivan told <a href="https://www.thehindu.com/news/national/isros-mini-launcher-sslv-is-unborn-but-has-2-flights-booked/article28859854.ece">The Hindu</a> that a single earth observation satellite will be launched to test the SSLV before the end of the year before the rocket is launched commercially in early 2020. Large vehicle launches Since the SSLV is the smallest vehicle that ISRO has, large vehicle missions imply that ISRO will be using the Geosynchronous Satellite Launch Vehicle (GSLV) that can launch up to 2-tonne class of communication satellites or the PSLV rockets that can carry up to 1,750 kilograms. The upgraded variant of the GSLVs, the GSLV Mk III, is capable of launching 4-tonne class of satellites. It’s also called the ‘<a href="https://www.businessinsider.in/countdown-for-bahubali-to-fly-with-chandrayaan-2-to-begin-on-sunday/articleshow/70202041.cms">Bahubali</a>’ of rockets and was used to launch India’s second mission to the moon — <a href="https://www.businessinsider.in/indias-most-powerful-launcher-will-carry-chandrayaan-2-on-moon-mission/articleshow/70202043.cms">Chandrayaan 2</a>. Missions using these rockets are launched from the Satish Dhawan Space Center in Sriharikota. "As usual, team ISRO will rise to the occasion to meet the challenges and requirements, and make every mission a grand success," said Sivan.
