preface
Space exploration has been one of the most exciting areas in the history of science. Recently, India's lunar program has attracted much attention, and they have sent the Chandrayaan-3 and Pragian lunar rovers to the south pole of the moon, intending to make a name for themselves on the international stage. Unfortunately, however, this feat ended in failure, and the Pragian lunar rover went into hibernation mode and failed to complete its mission. The incident sparked widespread controversy and a discussion about whether space exploration is a science and technology competition or an international arena. Does India's defeat mean that only a few countries will emerge from the space race? If you are also interested, please like and support, let's read on.
Background to the lunar exploration program
When India's Chandrayaan-3 successfully landed on the south pole of the moon and carried the Pragian lunar rover, space exploration enthusiasts around the world were excited. It's a high-profile space race, and India seems poised for a successful splendor. However, a sudden news changed everything: the rover went dormant and failed to fulfill any mission. Is this success or the greatest irony?
Different ways to go to the moon
First, let's review the background of this moonshot race. India has adopted a less common way to land on the moon, which requires rockets to fire multiple times around the Earth before entering the Earth-Moon transfer orbit. This method is both inefficient and fuel-intensive, resulting in India having to cut the weight of its lunar landing equipment. In contrast, China's Chang'e series uses a more efficient way to land on the moon, carrying more scientific instruments and equipment.
The gap between devices
Compared with China's Chang'e series, there is a huge gap between the equipment of India's Chandrayaan-3. The Chang'e series carries a number of scientific instruments, while Chandrayan-3 carries only two X-ray detectors and laser detectors, and the lunar rover is as light as a feather, only 26 kilograms. Compared with the Chinese Jade Rabbit, it can almost be said to be "lagging behind by a long margin". This strategy of "cutting the foot" on the lunar rover is now obvious.
Lunar environment and insulation challenges
The lunar environment is extremely harsh, with no atmosphere, and huge temperature differences between day and night, ranging from minus 190 degrees Celsius to 130-150 degrees Celsius. Therefore, thermal insulation is essential for the proper operation of the detector. China's Jade Rabbit has a nuclear-powered heating device that ensures that the body is maintained at the right temperature, which can be controlled between minus 50 and 70 degrees Celsius. However, India's lunar rover has no heat source, insulation or insulation, making it nearly impossible to succeed in such a harsh environment.
The impact of the international community
Why is India going all-in on this seemingly low-chance lunar landing? The answer is simple: since the end of the Cold War, only China has successfully landed on the moon, and other countries such as Israel, Japan, and Russia have tried but failed. In this case, if India becomes the second country to successfully land on the moon, it will have a positive impact on its international prestige. This also explains its relatively low investment in the project, with Chandrayaan-3 costing only $75 million, and India choosing the most challenging lunar landing site to boost the mission's newsworthiness.
Task result and reason for failure
However, the final mission result was that the rover went dormant and failed to fulfill its mission. This failure is not only disappointing, but also provokes people to think about the reasons for the failure. In addition to the technical challenges, India's lunar mission had significant shortcomings in its design and execution. Unlike China, India seems to focus more on social impact than on the requirements of science and technology. This made India's mission appear hasty and immature, which ultimately led to failure.
The competition for space exploration
Space exploration is a competitive field, and success requires a combination of science, technology, and more. China has made remarkable progress in this regard, and the construction of a lunar base and deep space exploration have become strategic goals of China's space industry. At the same time, India has tried to boost its international prestige through its success in space, but this short-sighted approach is not destined to lead to long-term success.
conclusion
The failure of India's lunar rover, Pragian, is not only regrettable, but also a reminder that space exploration requires a combination of science, technology and many aspects. International prestige, important as it is, is no substitute for actual scientific and technological prowess. China's success in space exploration is well deserved, while India's failure is a valuable lesson, and I hope they can learn from it and achieve more success in space exploration in the future. In the field of space exploration, there are endless stories of success and failure. The failure of India's Pragian lunar rover is a regrettable attempt, but also a reminder of the reality of space exploration. This failure teaches us that space exploration is not just an arena of international prestige, but also a challenge of science, technology and resilience.
However, failure is not the end. It should be a new starting point, inspiring more innovation and effort. We can learn more from our failures, refine our technology, improve our ability to execute, and be well prepared for the journey of discovery ahead. China's path of space exploration tells us that strength and perseverance are the keys to success, and science and technology are the driving force for mankind. So let's stay tuned for space exploration and expect more surprises and breakthroughs. Whether on Earth or in the universe, the spirit of human exploration never stops.
