Chandrayaan is a series of Indian lunar exploration missions. The first mission, Chandrayaan-1, was launched in October 2008. The second mission, Chandrayaan-2, was launched in July 2019.

The Chandrayaan missions have achieved a number of significant milestones, including:

* The discovery of water ice on the Moon's surface.

* The first high-resolution images of the lunar poles.

* The first detailed study of the lunar surface composition.

* The first landing of an Indian spacecraft on the Moon.

The Chandrayaan missions have made significant contributions to our understanding of the Moon. They have also helped to pave the way for future lunar exploration missions.

Here is a summary of the initiation and achievements of the Chandrayaan missions:

**Chandrayaan-1**

* Launched: October 22, 2008

* Orbited the Moon for 312 days

* Discovered water ice on the Moon's surface

* Took the first high-resolution images of the lunar poles

* Studied the lunar surface composition

**Chandrayaan-2**

* Launched: July 22, 2019

* Orbited the Moon for 56 days

* Landed the Vikram lander on the Moon's surface

* Deployed the Pragyan rover on the Moon's surface

* Discovered a new crater on the Moon's surface

The Chandrayaan missions are a testament to the ingenuity and perseverance of the Indian Space Research Organization (ISRO). They have made significant contributions to our understanding of the Moon and have helped to pave the way for future lunar exploration missions.

Here are some of the future plans for the Chandrayaan missions:

* Chandrayaan-3: A planned mission to land a rover on the Moon's South Pole.

* Chandrayaan-4: A planned mission to study the Moon's atmosphere and dust environment.

* Chandrayaan-5: A planned mission to collect and return lunar samples to Earth.

The Chandrayaan missions are a significant part of India's space program. They have helped to make India a leading player in the field of lunar exploration. The future plans for the Chandrayaan missions are ambitious, and they have the potential to make even more significant contributions to our understanding of the Moon.

The Chandrayaan program is a series of Indian lunar exploration missions. The first mission, Chandrayaan-1, was launched in 2008 and successfully orbited the Moon for 10 months. The second mission, Chandrayaan-2, was launched in 2019 and successfully entered lunar orbit. However, the lander Vikram and rover Pragyan failed to land safely on the Moon's surface.

Here are some of the achievements of the Chandrayaan program:

* Chandrayaan-1 discovered the presence of water ice on the Moon's surface.

* Chandrayaan-1 mapped the Moon's surface in unprecedented detail.

* Chandrayaan-2 provided new insights into the Moon's geology and history.

The Chandrayaan program is a significant achievement for ISRO and for the international community of lunar scientists. The program has helped to advance our understanding of the Moon and its potential as a future destination for human exploration.

Here is a timeline of the Chandrayaan program:

* **2003:** Chandrayaan program approved by the Indian government.

* **2008:** Chandrayaan-1 launched on October 22.

* **2008-2009:** Chandrayaan-1 orbits the Moon and successfully completes its mission.

* **2013:** Chandrayaan-2 mission approved by the Indian government.

* **2019:** Chandrayaan-2 launched on July 22.

* **2019:** Chandrayaan-2 enters lunar orbit on August 20.

* **2019:** Vikram lander and Pragyan rover attempt to land on the Moon on September 6, but fail due to a software glitch.

The Chandrayaan program is ongoing, and ISRO is planning to launch a third mission in the near future. The third mission, Chandrayaan-3, will attempt to land a rover on the Moon's surface.

The Chandrayaan program is a series of Indian lunar exploration missions. The first mission, Chandrayaan-1, was launched in October 2008. The second mission, Chandrayaan-2, was launched in July 2019.

The Chandrayaan program has achieved a number of significant milestones, including:

* The discovery of water ice on the Moon.

* The mapping of the Moon's surface in unprecedented detail.

* The study of the Moon's geology and mineralogy.

* The exploration of the Moon's polar regions.

The Chandrayaan program has also made a number of important contributions to our understanding of the Moon, including:

* The Moon's water ice may have been deposited by comets or asteroids.

* The Moon's crust is much thinner than previously thought.

* The Moon's mantle is much more heterogeneous than previously thought.

* The Moon's polar regions may be a source of resources for future human exploration.

The Chandrayaan program is a major success for ISRO and for the international community of lunar scientists. The program has made significant contributions to our understanding of the Moon and its potential for future human exploration.

Here is a table of the Chandrayaan missions and their achievements:

| Mission | Launch Date | Achievements |

|---|---|---|

| Chandrayaan-1 | October 22, 2008 | Discovered water ice on the Moon, mapped the Moon's surface in unprecedented detail, studied the Moon's geology and mineralogy. |

| Chandrayaan-2 | July 22, 2019 | Crash-landed on the Moon's surface, but successfully deployed its orbiter and lander, Vikram. |

The Chandrayaan program is ongoing, and future missions are planned to further explore the Moon.
