3. Chandrayaan-1
Chandrayaan-1 (Sanskrit: चन्द्रयान-१: Moon vehicle was India's first lunar probe. Chandrayaan-1, India's first mission to Moon, was launched successfully on October 22, 2008 from SDSC-Satish Dhawan, SHAR, Sriharikota.
The mission included a lunar orbiter and an impactor*. India launched the spacecraft using a PSLV-XL rocket, serial number C11.[01]
The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon.
*Impactor – (spacecraft), a craft designed for high velocity landing

4. Chandrayaan-1 - Introduction
The spacecraft carries 11 scientific instruments(payloads)built in India, USA, UK, Germany, Sweden and Bulgaria.
The mission was a major boost to India's space program, [01]as India researched and developed its own technology in order to explore the Moon. [01]  
The vehicle was successfully inserted into lunar orbit on 8 November 2008.
 India the fourth country to place its flag on the Moon. [01]

7. Chandrayaan-1 – Mission Objective
The probe impacted near the crater Shackleton at 20:31 ejecting sub-surface soil that could be analyzed for the presence of lunar water ice. [01]
The estimated cost for the project was ₹3.86 billion. Theremote sensing lunar satellite had a mass of 1,380 kg (3,040 lb) at launch and 675 kg (1,488 lb) in lunar orbit. [01]  
It carried high resolution remote sensing equipment for visible, near infrared, and soft and hard X-ray frequencies.
Over a period, it was intended to survey the lunar surface to produce a complete map of its chemical characteristics and three-dimensional topography. 

8. Chandrayaan-1 – Mission Objective
The lunar mission carried five ISRO payloads and six payloads from other space agencies including NASA, ESA, and the Bulgarian Aerospace Agency, which were carried free of cost. [01]
Chandrayaan operated for 312 days as opposed to the intended two years but the mission achieved 95% of its planned objectives. [01]
Among its many achievements, the greatest achievement was the discovery of the widespread presence of water molecules in the lunar soil. [01]

Mass
Dimensions
1,380 kg at launch, 675 kg at lunar orbit,[01] and 523 kg after releasing the impactor.

10. Impact of the MIP on the lunar surface
The Moon Impact Probe (MIP) crash landed on the lunar surface on 14 November 2008, 15:01 UTC (20:31 Indian Standard Time (IST)) near the crater Shackleton at the south pole. The MIP was one of eleven scientific instruments (payloads) on board Chandrayaan1.[01]
The MIP separated from Chandrayaan at 100 km from lunar surface and began its nosedive at 14:36 UTC (20:06 IST). going into free fall for thirty minutes. As it fell, it kept sending information back to the mother satellite which, in turn, beamed the information back to Earth. The altimeter then also began recording measurements to prepare for a rover to land on the lunar surface during a second Moon mission – planned for [01]
Following the successful deployment of the MIP, the other scientific instruments were turned on, starting the next phase of the mission.[01]

14. Awards for Chandrayaan1
The American Institute of Aeronautics and Astronautics (AIAA) has selected ISRO's Chandrayaan1 contributions to space science and technology. [01]
The International Lunar Exploration Working Group awarded the Chandrayaan1 team the International Cooperation Award in 2008 for accommodation and tests of the most international lunar payload ever (from 20 countries, including India, the European Space Agency of 17 countries, USA, and Bulgaria).[01]
US based National Space Society awarded ISRO the 2009 Space Pioneer Award in the science and engineering category, for the Chandrayaan1 mission.[01]

15. Team : Chandrayaan1
The scientists considered instrumental to the success of the Chandrayaan1 project are:[01]
G. Madhavan Nair – Chairman, Indian Space Research Organisation
Dr. T. K. Alex – Director, ISAC (ISRO Satellite Centre)
Dr.Mylswamy Annadurai – Project Director, Chandrayan1
S. K. Shivkumar – Director – Telemetry, Tracking and Command Network
Mr. M.Pitchaimani – Operations Director, Chandrayan1
Mr. Leo Jackson John – Spacecraft Operations Manager, Chandrayan1
Dr. K. Radhakrishnan (scientist) – Director, VSSC George Koshy – Mission Director, PSLVC11
Srinivasa Hegde – Mission Director, Chandrayaan1
Prof. J N Goswami – Director of Physical Research Laboratory and Principal Scientific Investigator of Chandrayaan1

16. Chandrayaan 2 Chandrayaan2
ISRO is currently developing a second version of Chandrayaan named Chandrayaan2 possibly to be launched in 2016—2017.[01] The Indian Space Research Organization (ISRO) plans to include a robotic rover as a part of its second Chandrayaan mission. The rover will be designed to move on wheels on the lunar surface, pick up samples of soil or rocks, do onsite chemical analysis and send the data to the Earth via the Chandrayaan2 orbiter, which will be orbiting the Moon.
