Moon Impact Probe(MIP) The impact probe weighing 29 kg will ride piggyback on the top deck of the main orbiter and will be released at a predetermined time after the orbiter reaches the final 100km orbit to impact at a pre-selected location. During the descent phase it is in spin-stabilized configuration. The total flight time from release to impact on Moon will be close to twenty minutes. Major Objectives: Design, development and demonstration of technologies required for impacting a probe at a desired location on the moon. Qualify technologies required for future soft landing missions. Exploration of the moon from close range. Payload Configuration Details There will be three major payloads in the Moon Impact Probe Radar Altimeter - for measurement of altitude of the Moon Impact Probe above the lunar surface and qualify technologies for future landing missions. The operating frequency band is 4.3 GHz ± 100 MHz Video Imaging System - for acquiring images of the surface of moon from the descending probe. The video imaging system consists of analog CCD camera along with a video decoder Mass Spectrometer - A state-of-the-art Quadrupole mass spectrometer with a mass resolution of 0.5 amu and sensitive to partial pressure of the order of 10-15 torr for measuring the constituents of tenuous lunar atmosphere during descent. The dimension of the impact probe is 375 mm x 375 mm x 470 mm MIP Structure with all its subsystems Impact Probe Mission Profile
At 8:34 pm Indian time Friday night (1504 UTC), India became the fourth country to land its flag on the Moon.
The unmanned lunar orbiter Chandrayaan-1 ejected its Moon Impact Probe (MIP), which hurtled across the surface of the Moon at 1.5 kilometres per second (3000 miles per hour), and successfully crash landed near the Moon's south pole.
Besides carrying three important scientific instruments, the lunar probe also carried the image of the Indian national flag, painted on all sides.

Chandrayaan-1 (meaning 'Moon craft' in Sanskrit) reached its target lunar orbit on Wednesday.  The orbiter will remain in a circular orbit 102 kilometres above the Moon's surface for two years.  Its instruments will be gradually commissioned over the next few days.

With this landing, India became both the fourth country to place a flag on the Moon and the fifth group to send a spacecraft to the Moon. The other countries which have sent spacecraft to the Moon are the United States, the former Soviet Union, Japan, and China, along with the European Space Agency (ESA), a consortium of 17 countries.  
Japan and China currently each have scientific satellites orbiting the Moon, though China has not yet put a spacecraft on the moon's surface.

The MIP has a mass of 29 kg, is about the size of a microwave oven, and was designed and assembled in India.
After the orbiter ejected it, the probe took about 25 minutes to reach the Moon's surface. 
On-board digital cameras made a high resolution movie of the surface during descent, and scientists also conducted measurements with the probe's mass spectrometer and radar altimeter.
Data was beamed back to India via the orbiter, and it is currently being processed and analysed.

Data from the altimeter experiments will be used to refine the instrument in order to control the soft landing of a future probe.  
Plans are already being prepared for the Chandrayaan-2 to be launched by 2012.

India's first lunar mission was launched from the Satish Dhawan Space Centre on the Andhra Pradesh coast on October 22.
The launch vehicle was an Indian designed and built rocket that had been previously proven by carrying scientific and commercial payloads to earth orbit, including weather and communications satellites.
The cost of this mission is estimated at 340 crore (3.4 billion) rupees (US$78 million). 
The mission carries five scientific instruments built by India's technology sector, and six developed cooperatively with foreign nations.

Goals for the orbiter include making a detailed map of the Moon's chemical make-up and mineral resources, as well as a three-dimensional digital map of the entire surface. 
The mission will examine the surface for sources of water, and take comparison photos of the light side and dark sides of the surface.
