Chandrayaan-3 Completes Last Moon-Bound Manoeuvre

By LokMarg

Indian Space Research Organisation (ISRO) on Wednesday successfully carried out the final orbit reduction manoeuvre of the Chandrayaan-3 spacecraft, a week ahead of its scheduled landing on the moon.

“Today’s successful firing, needed for a short duration, has put Chandrayaan-3 into an orbit of 153 km x 163 km, as intended. With this, the lunar bound manoeuvres are completed,” ISRO said today.

The spacecraft that was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on July 14 this year is expected to touchdown on the South Polar region of the Moon on August 23.

A GSLV Mark 3 (LVM 3) heavy-lift launch vehicle was used for the launch of the spacecraft that was placed in the lunar orbit on August 5 and since then it has been through a series of orbital manoeuvres been lowered closer to the moon’s surface.

Today’s fifth and final orbit-reduction manoeuvre was performed from ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru.

With the lunar-bound manoeuvres now concluded, ISRO said that the focus of the Chandrayaan-3 mission shifts towards the next stages of preparations as the Propulsion Module and the Lander Module gear up “for their separate journeys.”

Separation of the Lander Module from the Propulsion Module is planned for August 17.

Union Minister Jitendra Singh posted on X, “A step closer towards the MOON! Today’s successful firing, needed for a short duration, has put Chandrayaan3 into an orbit of 153 km x 163 km, as intended. With this, the lunar bound maneuvres have been completed.”

ISRO is attempting to make a successful soft landing on the Moon, which will make India the fourth country in the world to achieve the feat, joining the ranks of the United States, Russia and China.

India’s third lunar mission, Chandrayaan-3, marks the country’s second attempt at a gentle lunar landing. It is a follow-up to Chandrayaan-2, the moon mission that failed in 2019. It will show off India’s complete capability for a secure lunar landing and roaming.

The components of Chandrayaan-3 include several electronic and mechanical subsystems designed to ensure a gentle and safe landing, including guidance and control systems, propulsion systems, and navigation sensors. There are also systems for releasing the rover, antennas for two-way communication, and other onboard electronics.

Chandrayaan-3’s declared goals include a secure and soft landing, lunar rover wandering, and in-situ scientific research. (ANI)

The Chandrayaan-3 spacecraft, which covered about two-thirds of the distance to the Moon since its launch, successfully entered into the Lunar orbit on Saturday, according to ISRO.

“MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity,” Indian Space Research Organisation (ISRO) tweeted. 

“Chandrayaan-3 has been successfully inserted into the lunar orbit. A retro-burning at the Perilune was commanded from the Mission Operations Complex (MOX), ISTRAC, Bengaluru. The next operation – reduction of orbit – is scheduled for Aug 6, 2023, around 23:00 Hrs. IST,” ISRO added. 

Chandrayaan-3, India’s third lunar exploration mission, was launched on GSLV Mark 3 (LVM 3) heavy-lift launch vehicle successfully from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on July 14.

Notably, this is the fourth country after the US, China, and Russia, that landed its spacecraft on the surface of the moon and demonstrate the country’s ability for a safe and soft landing on the lunar surface.

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.

Chandrayaan-3 components include various electronic and mechanical subsystems intended to ensure a safe and soft landing such as Navigation sensors, propulsion systems, guidance & control among others. Additionally, there are mechanisms for the release of Rover, two-way communication-related antennas and other onboard electronics.

The stated objectives of Chandrayaan-3 are safe and soft landing, rover roving on the moon’s surface, and in-situ scientific experiments.

The approved cost of Chandrayaan-3 is Rs. 250 crores (Excluding Launch Vehicle Cost).Chandrayaan-3’s development phase commenced in January 2020 with the launch planned sometime in 2021. However, the Covid-19 pandemic brought an unforeseen delay to the mission’s progress.Chandrayaan-3 is the ISRO’s follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing on the lunar surface in 2019 and was eventually deemed to have failed its core mission objectives.

The key scientific outcomes from Chandrayaan-2 include the first-ever global map for lunar sodium, enhancing knowledge on crater size distribution, unambiguous detection of lunar surface water ice with IIRS instrument and more. The mission has been featured in almost 50 publications.

Chandrayaan-3: Spacecraft Covers Two-Thirds Of Distance To Moon

By LokMarg

The Chandrayaan-3 spacecraft, which was launched on GSLV Mark 3 (LVM 3) heavy-lift launch vehicle successfully from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on July 14, has covered about two-thirds of the distance to the Moon.

“The spacecraft has covered about two-thirds of the distance to the moon. Lunar Orbit Injection (LOI) set for Aug 5, 2023, around 19:00 Hrs. IST,” Indian Space Research Organisation (ISRO) tweeted Friday.

Chandrayaan-3, India’s third lunar exploration mission, will make India the fourth country after US, China, and Russia, to land its spacecraft on the surface of the moon and demonstrate the country’s abilities for safe and soft landing on the lunar surface.

The spacecraft was successfully launched onboard LVM-3 on July 14, 2023, at 14:35 IST. The spacecraft is currently undergoing a series of orbit manoeuvres with the objective of reaching the moon’s orbit.

Chandrayaan-3 will take nearly 33 days from the launch date to reach the orbit of the moon. 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.

Chandrayaan-3 components include various electronic and mechanical subsystems intended to ensure a safe and soft landing such as Navigation sensors, propulsion systems, guidance & control among others.

Chandrayaan-3 launch

Chandrayaan-3: Spacecraft Lifts Off Successfully From Sriharikota

By LokMarg

The wait is over as Chandrayaan-3 was launched on GSLV Mark 3 (LVM 3) heavy-lift launch vehicle successfully from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota as per scheduled launch time.

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.
Chandrayaan-3, India’s third lunar exploration mission, will make India the fourth country after US, China, and Russia, to land its spacecraft on the surface of the moon and demonstrate the country’s abilities for safe and soft landing on lunar surface.

Chandrayaan-3 is the ISRO’s follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing on the lunar surface in 2019 and was eventually deemed to have failed its core mission objectives.

Chandrayaan-3 will be inserted into the Lunar Transfer Trajectory after the orbit raising maneuvers. Covering a distance of over 300,000 km, it will reach the Moon in the coming weeks. Scientific instruments onboard will study the Moon’s surface and enhance our knowledge.

Chandrayaan-3 is equipped with a lander, a rover and a propulsion module. It weighs around 3,900 kilograms.

Moon serves as a repository of the Earth’s past and a successful lunar mission by India will help enhance life on Earth while also enabling it explore the rest of the solar system and beyond.

July 14, 2023 will always be etched in golden letters in the annals of India’s space sector history, said Prime Minister Narendra Modi, ahead of the launch of much-awaited Chandrayaan-3, India’s third lunar mission.

“This remarkable mission will carry the hopes and dreams of our nation,” PM Modi had tweeted earlier.

“Thanks to our scientists, India has a very rich history in the space sector. Chandrayaan-1 is considered to be a path breaker among global lunar missions as it confirmed the presence of water molecules on the moon. It featured in over 200 scientific publications around the world,” PM Modi wrote on Twitter.

“Till Chandrayaan-1, the moon was believed to be a bone-dry, geologically inactive and uninhabitable celestial body. Now, it is seen as a dynamic and geologically active body with the presence of water and sub-surface ice,” he added, asserting it might be potentially inhabited in the future.

Chandrayaan-2 was equally pathbreaking because data from the Orbiter associated with it detected the presence of chromium, manganese and sodium for the first time through remote sensing. This will also provide more insights into the moon’s magmatic evolution, PM Modi stated.

The key scientific outcomes from Chandrayaan-2 include the first ever global map for lunar sodium, enhancing knowledge on crater size distribution, unambiguous detection of lunar surface water ice with IIRS instrument and more. The mission has featured in almost 50 publications.

Extending best wishes for the Chandrayaan-3 mission, PM Modi urged people to know more about this lunar mission and the strides India has made in space, science and innovation. “It will make you all very proud,” he added.

Chandrayaan-3’s development phase commenced in January 2020 with the launch planned sometime in 2021. However, the Covid-19 pandemic brought an unforeseen delay to the mission’s progress.

K Sivan, former director of ISRO, told ANI that the success of mission Chandrayan-3 will give a morale boost to programmes like Gaganyan, India’s first manned space mission.

Former ISRO scientist Nambi Narayanan, who has been instrumental in the country’s space sector innovation, said on Thursday the Chandrayaan-3 mission is going to be successful and a game-changer event for India.

”Chandrayaan-3 will definitely be a game changer for India and I hope it will be successful. India will become an inspiration to the entire world. Let’s wait for the launch and pray for the best,” Nambi Narayanan told ANI.

“I’m assuming, and I hope that it will be a successful mission. Because whatever the problem in Chandrayaan-2, actually, we corrected the whole thing. From the failure, we have understood all mistakes (on our part),” Narayanan, the recipient of India’s third highest civilian honour, ‘Padma Bhushan’, told ANI.(ANI)

Chandrayaan-3 countdown

Chandrayaan-3: Countdown Begins For India’s Third Moon Mission

By LokMarg

Chandrayaan-3, 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 ANI 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)
