Kolkata (West Bengal) : As the Chandrayaan-3 spacecraft, which has covered about two-thirds of the distance to the Moon since its launch, successfully entered into the Lunar orbit on Saturday, former ISRO scientist Tapan Mishra said the lunar mission was an illustration of the country breaking new grounds in space exploration.
Speaking to ANI in Kolkata, Mishra said, "Our rockets (launch vehicles) are not very powerful. Once the rockets escape the earth, they need a velocity of 11.2 km/s to make further progress. Since our launch vehicles don't operate at such velocity, we resorted to the sling-slot mechanism."
Earlier, on Saturday, a post in the official Twitter handle of ISRO read, "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."
“MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity,” Indian Space Research Organisation (ISRO) added in another tweet. 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.
India will become only the fourth country after the US, China, and Russia to land 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. (ANI)
