ISRO Updates Lander for Next Moon Mission
The Indian Space Research Organisation (ISRO) has announced that it has made changes to the lander for its next moon mission.
The lander, which was originally designed with five engines, will now have four engines. In addition, the software has been updated.
ISRO says that the changes were made in response to the lessons learned from the last moon mission, Chandrayaan-2. In September 2019, Chandrayaan-2's lander, Vikram, lost contact with Earth shortly before it was due to land on the moon.
The cause of the failure is still unknown, but ISRO believes that the changes to the lander will help to prevent a similar failure from happening in the future.
The updated lander is expected to be launched in 2023. Once it lands on the moon, it will collect data about the lunar surface and atmosphere. The data will help scientists to better understand the moon and its history.
New Delhi: India's Chandrayaan-3 is set to launch today at 2:35 pm from Sriharikota in Andhra Pradesh. The mission is carrying the hopes of an entire nation, as it will make India the fourth country to land on the moon.
Top 10 Most Points of Chadrayaan-3 2023
1. The moon lander Vikram will be perched on a GSLV Mark 3 heavy-lift launch vehicle, also known as the Bahubali rocket. The GSLV stands 43.5 meters tall, half the height of Delhi's Qutb Minar. Renamed Launch Vehicle Mark 3 (LM-3), the journey will take over 40 days, and the spacecraft is expected to touchdown on the moon on August 23.
2. The Indian Space Research Organisation (ISRO) is hoping for better luck with its next moon mission, after its last attempt in July 2019 ended in failure.
3. The main lacuna in the last Chandrayaan-2 mission was that there were off-nominal conditions that were initiated in the system. Everything was not nominal. And the craft was not able to handle the off-nominal condition for a safe landing," ISRO Chief S Somnath told NDTV in an exclusive interview.
4. The discovery of water molecules on the Moon was a major surprise in 2008, when it was made by India's first moon mission, Chandrayaan-1. The finding has since been confirmed by other missions, and it has led to a renewed interest in the Moon as a potential source of resources for future human exploration.
5. Vikram is designed to land on the moon gently. Once it has landed safely, it will release the rover Pragyan. Pragyan will then explore the moon's surface for a lunar day, which is equal to 14 Earth days. During its time on the moon, Pragyan will conduct a variety of scientific experiments.
6. The scientists hope to analyze the lunar soil, rove around the moon's surface, and also log moonquakes.
7. ISRO has made changes to its lander for its next moon mission. The agency has reduced the number of engines from five to four, and has also updated the software. These changes were made after learning from the last moon mission, which experienced some technical difficulties. The lander has undergone rigorous testing, and ISRO is confident that it is ready for its next mission.
8. Somanath explained that the new mission had been designed to land successfully even if some of its components failed. They had considered several scenarios, such as sensor failure, engine failure, algorithm failure, and calculation failure. For each scenario, they had developed measures to counteract it.
9. India's maiden mission to the Moon, Chandrayaan-1, launched in October 2008. It remained operational until August 2009, when contact with the spacecraft was lost.
10. In 2019, the Chandrayaan-2 lander veered off course and crashed into the Moon. The orbiter, however, is still circling the lunar surface and sending back data.
Conclusion
In 2019, the Chandrayaan-2 lander veered off course and crashed into the Moon. The In conclusion, the Chandrayaan-3 mission is a major milestone for India's space program.
Building on the knowledge and experience gained from previous missions, Chandrayaan-3 is well-positioned to overcome the challenges of a lunar landing and make significant scientific discoveries.
The mission's goals of exploring the lunar surface, returning samples to Earth, and advancing lunar exploration technologies will help us to better understand the Moon's geology and origin, and could even shed light on the origins of life on Earth.
