Introduction:

In the vastness of the universe, the pace of human exploration of space has never stopped. At 17:05 p.m. on July 14, Indian Chandrayaan-3 successfully launched, embarking on an unknown journey. However, the good times did not last long, and the emergence of orbital deviations brought huge challenges to the task.

The orbit deviation of Indian Chandrayaan-3 was relatively large, and the Perigee and Apogee were lower than the original plan.

India's Chandrayaan-3 launch was initially successful, but behind the joy was a series of worrying intelligence data. According to the data of the United States Space Force 18SDS, Chandrayaan-3 entered an orbit that was significantly different from the original plan. The Perigee was about 32 kilometers lower than expected, and the Apogee was about 194 kilometers lower.

In addition, orbit deviation also imposes higher requirements on fuel consumption and flight operations. In order to raise the Apogee to the preset altitude, Chandrayaan-3 needs to consume more fuel. However, currently we are not clear about its fuel redundancy situation, which may lead to insufficient fuel supply and further affect the success of landing and subsequent missions.

In addition, Chandrayaan-3 needs to conduct multiple orbit changes and near moon braking operations on the Orbit of the Moon to adjust the orbit and gradually approach the moon. However, the existence of orbital deviations makes these operations more complex and difficult. Compared with the conventional scheme that only a few countries such as China and the United States need orbit change operations, the Indian Chandrayaan-3 needs frequent operations, which will consume more time and fuel and increase the risk of mission failure.

In the face of these challenges, the four small thrust variable thrust engines carried by Chandrayaan-3 will face greater pressure. The total thrust is less than half of Chang'e 3 and Chang'e 4, which means that the propulsion efficiency of Chandrayaan-3 is low, which further aggravates the uncertainty of the mission.

Although India has made some achievements in the space field and accumulated the experience of Chandrayaan-1, Chandrayaan-2 and the Mars probe MOM, the current orbital deviation has brought significant uncertainties and risks to the mission of Chandrayaan-3. There are still huge challenges and suspense whether we can successfully reach the Orbit of the Moon.

Chandrayaan-3 may face the problem of fuel shortage, because it needs more fuel to lift more orbits.

The Indian Chandrayaan-3 is facing a serious challenge - the problem of fuel supply. Due to orbital deviation, Chandrayaan-3 needs to consume more fuel in order to raise the Apogee to a predetermined height. However, at present, we are not clear about the fuel redundancy carried by Chandrayaan-3, which makes the success of the mission a major uncertainty.

When a spaceship moves from low orbit to a higher orbit, it needs to carry out thrust acceleration to overcome Gravity of Earth and finally enter the target orbit. However, raising more orbits means higher fuel consumption. Since Chandrayaan-3 entered a large orbit deviation, more fuel is needed to correct the orbit and raise the Apogee to the required height. But if the fuel supply is insufficient, the prospects for mission success will become worrisome.

In addition, Chandrayaan-3 is also faced with the challenge of multiple near moon braking and orbit change operations in Orbit of the Moon. These operations require precise calculations and thrust control to adjust the orbit and gradually approach the lunar surface. However, due to the uncertainty of fuel supply, Chandrayaan-3 may not be able to perform all scheduled operations, thus reducing the probability of success of the mission.

For space missions, the importance of fuel is self-evident. The spacecraft needs sufficient fuel reserves to complete various mission stages, including entering the target orbit, orbit change, lunar braking, and final landing. If the fuel is depleted, the spacecraft will be unable to continue flying or complete critical operations, making mission failure possible.

However, in space missions, fuel supply is limited. The spacecraft must consider fuel consumption during the design phase and make reasonable redundancy planning. For Chandrayaan-3, the lack of fuel redundancy may have a significant impact on the success of the mission.

India needs to accurately assess the fuel reserves carried by Chandrayaan-3 and ensure that it is sufficient to complete all stages of the mission. At the same time, they also need to be flexible and make corresponding adjustments based on real-time data and situations to maximize the success rate of tasks.

Although India has accumulated some experience and technical capabilities in the space field, facing the risk of insufficient fuel, there is still huge uncertainty whether Chandrayaan-3 can successfully reach Orbit of the Moon. This requires a combination of precise calculations, scientific decision-making, and skilled operations from the Indian team to overcome challenges and achieve the great goal of exploring the sea of stars.

Chandrayaan-3 conducted multiple orbit change and near moon braking operations in Orbit of the Moon, which took a long time and challenged fuel consumption and flight safety.

After the Indian Chandrayaan-3 entered orbit, it was faced with a series of complex manipulation operations, including multiple orbital changes and near moon braking, to achieve the ultimate goal of reaching the moon. However, these operations are time-consuming and pose significant challenges to fuel consumption and flight safety.

In order to adjust its orbit and gradually approach the moon, Chandrayaan-3 needs to conduct continuous orbit change operations. Orbit change means changing the speed and direction of a spacecraft to enter a predetermined orbit. In Orbit of the Moon, the orbit change frequency is higher, because it needs to slightly adjust the spacecraft's orbit path to ensure accurate approach to the moon surface. However, this operation requires precise calculations and exquisite thrust control to avoid excessive or insufficient orbit changes, which can affect the smooth progress of subsequent tasks.

In addition to track change, Chandrayaan-3 also needs to carry out many near moon braking operations. The braking of the near moon is to slow down and reduce the speed of the spacecraft as it approaches the moon, in order to achieve a safe landing. However, this braking process involves precise control and timing of thrust. Moreover, the near moon braking also requires stability during flight to avoid excessive friction and damage to the spacecraft structure.

These complex control operations not only consume time, but also pose challenges to fuel consumption and flight safety. Due to the increased demand for lifting the Apogee due to the track deviation, Chandrayaan-3 will need more fuel to complete the orbit change and lunar braking operations. This increases the pressure on fuel supply, making the success of the task even more uncertain.

In addition, prolonged control and flight pose higher requirements for the reliability and safety of spacecraft systems. During the whole mission, Chandrayaan-3 must maintain stable communication and navigation, as well as good energy management and thermal control, to ensure the normal operation of the spacecraft and the safety of astronauts.

Faced with these challenges, India needs to fully evaluate the fuel reserves of its spacecraft and develop precise control plans. At the same time, they also need to maintain real-time communication with the spacecraft and make flexible adjustments according to changing circumstances. This requires the team to have strong technical capabilities and flight experience to cope with complex mission environments.

Although Chandrayaan-3 is faced with difficulties such as time-consuming, increased fuel consumption and flight safety challenges under orbital deviation, the Indian team will work hard to overcome these problems and strive to achieve the great goal of exploring the moon. Their determination and effort will be the key factors determining the success of the task. Let's look forward to and support their exploration journey together.

It is difficult for Chandrayaan-3 to land, and there is only one chance to land at Lunar south pole.

In the lunar exploration mission of Indian Chandrayaan-3, it is faced with a very challenging task - landing at Lunar south pole. However, due to the limitation of orbit deviation and mission design, Chandrayaan-3 has only one opportunity to carry out this important landing operation.

The Lunar south pole region is a landing site full of risks and challenges. First, the terrain of the Lunar south pole is complex and changeable, including high mountains, deep valleys and steep slopes. This terrain makes the landing process more difficult, requiring the lander to accurately control the descent speed and attitude to avoid collisions with ground obstacles.

Secondly, due to the rotation of the moon, the lander needs to accurately calculate and predict the landing time. Once the ideal landing window is missed, it is impossible to try again, because the fuel supply is limited, Chandrayaan-3 is unable to make a second landing. This makes the landing mission to the Lunar south pole a golden opportunity.

In addition to the challenges of terrain and time window, Lunar south pole is also facing environmental factors such as extreme low temperature and extreme light. The surface temperature of the moon can reach minus 200 degrees Celsius, posing higher requirements for the tolerance of landers and detectors. In addition, in Lunar south pole, the solar illumination time is relatively short, which further limits the working time and mission execution ability of the lander.

In response to these challenges, the Indian team must accurately calculate and control the descent speed, attitude, and offset of the lander to ensure safe landing and avoid any potential damage. They also need to make full use of the instruments and sensors on the probe to quickly obtain and analyze key data of the landing site to support subsequent scientific research and survey missions.

Although Chandrayaan-3 faces huge challenges and risks, the Indian team will do its utmost to cope with them. They will rely on advanced navigation technology, accurate calculation and flexible operation to achieve the goal of landing at Lunar south pole. At the same time, they will also rely on global scientific cooperation and technological support to jointly promote human exploration of the moon.


The variable thrust engine with low thrust used on Chandrayaan-3 may affect the success of the mission.

The thrust of the variable thrust engine used on Chandrayaan-3 is relatively small, which may have an important impact on the success of the mission. Thrust is a key factor in various control operations of spacecraft, directly affecting the efficiency and accuracy of flight.

In the mission of Chandrayaan-3, insufficient thrust may have negative effects on many aspects. Firstly, insufficient thrust will affect the accuracy of the orbit change operation. Chandrayaan-3 needs to carry out multiple orbit change operations to adjust its orbit path and gradually approach the moon. However, due to the limited thrust, the orbit change operation will be limited, resulting in a reduction in the accuracy of adjustment, which may even affect whether Chandrayaan-3 can successfully enter the scheduled Orbit of the Moon.

Secondly, insufficient thrust will also have an impact on braking operations in recent months. In order to achieve a safe landing in Orbit of the Moon, Chandrayaan-3 needs to conduct multiple near lunar braking operations to slow down and adjust its orbit. However, due to the low thrust, braking operations in recent months may require longer time and distance, increasing the complexity of the task and the amount of fuel consumed.

In addition, insufficient thrust poses challenges to the landing phase. Chandrayaan-3 has only one chance to land at Lunar south pole, which requires that the lander can accurately control the descent speed and attitude to avoid collision with ground obstacles. However, low thrust may limit the precise control ability of the lander, increasing the risk and difficulty of landing.

In order to meet the challenge of insufficient thrust, the Indian team needs to fully evaluate the performance of the variable thrust engine carried by Chandrayaan-3, and develop corresponding flight plans and strategies. They may need to calculate the timing and use of thrust more accurately to maximize the effectiveness and success rate of the task.

At the same time, insufficient thrust also reminds us to fully consider the performance and thrust requirements of the propulsion system when designing spacecraft. The continuous improvement and innovation of propulsion technology will provide more options and possibilities for future Space exploration.

Conclusion:

The fate of Chandrayaan-3 is still shrouded in fog, full of unknown and challenges. However, regardless of success or failure, the courage and effort of the Indian team are worthy of our admiration. Let's look forward to their dream of exploring the sea of stars and strive together, and hope that they can overcome difficulties and achieve outstanding achievements. Regardless of the outcome, this exploration will pave the way for human space exploration and inspire us to continue pursuing unknown boundaries.
