Lun ar Orbit

Lunar Orbit basics: 

Lunar Orbit basics 1 : Aposelene ( Apoapsis) - 7502 Km 2 : Periselene ( Periapsis ) - 200 Km

Lunar Orbit Insertion: 

Lunar Orbit Insertion Chandrayaan-1 successfully completed the lunar orbit insertion operation on 8 Nov 2008 at 16:51 IST This maneuver involved firing of the liquid engine for 817 seconds (about thirteen and half minutes) when the spacecraft passed within 500 km from the Moon. The satellite was placed in an elliptical orbit that passed over the polar regions of the Moon, with 7502 km aposelene (point farthest away from the Moon) and 504 km periselene (nearest to the Moon). The orbital period was estimated to be around 11 hours. With the successful completion of this operation, India became the fifth nation to put a vehicle in lunar orbit

MIP ( Moon Impact Probe): 

MIP ( Moon Impact Probe) The Moon Impact Probe (MIP) developed by the Indian Space Research Organization (ISRO), India's national space agency, was a lunar probe that was released by ISRO's Chandrayaan-1 lunar remote sensing orbiter. The Moon Impact Probe separated from the moon-orbiting Chandrayaan-1 on 14 November 2008, 20:06 and crashed, as planned, into the lunar south pole after a controlled descent. The MIP struck the Shackle ton Crater at 20:31 on 14 November 2008 releasing underground debris that could be analyzed by the orbiter for presence of water/ice.

MIP Payload: 

MIP Payload The MIP carried three instruments: Radar Altimeter – which measured the altitude of the probe during descent and provided information on qualifying technologies for future landing missions. The operating frequency band was 4.3 GHz ± 100 MHz Video Imaging System – acquired close range images of the surface of the Moon during descent and before impact. The video imaging system consisted of an analog CCD camera. Mass Spectrometer based payload CHACE – measured trace constituents of the lunar atmosphere during descent. This instrument was a quadruple mass spectrometer with a mass resolution of 0.5 amu and sensitivities to partial pressures on the order of 1.3×10 −11 pascals.

MIP Objectives: 

MIP Objectives Design, development and demonstration of technologies required for impacting a probe at the desired location on the Moon. Qualify technologies required for future soft landing missions. Scientific exploration of the Moon from close range. Chardrayaan-1 is the first Indian Mission to the Moon devoted to high-resolution remote sensing of the lunar surface features in visible, near infrared, X-ray and low energy gamma ray regions.

Chandrayaan Remote Control: 

Chandrayaan Remote Control Ground Segment for Chandrayaan-1 comprises of three major elements : the Ground Station Network including the Indian Deep Space Network (IDSN) , Mission Operations Complex (MOX) Indian Space Science Data Centre (ISSDC) . This trio of ground facility ensures the success of the mission by providing to and fro conduit of communication, securing good health of the spacecraft, maintaining the orbit and attitude to the requirements of the mission and conducting payload operations. The ground segment is also responsible for making the science data available for the Payload Scientists along with auxiliary information, in addition to archiving of payload and spacecraft data. Payload Operation Centre's (POCs) also form a part of the Ground Segment .

Slide 11: 

It was a tremendous achievement in Indian space research program soon after historic launching of Chndrayaan-1 to the orbit of the Moon.  Once again India has proved that India is one of the advanced countries as concern to the space borne technology in the world. Being a one of the world’s advanced research centre the ISRO have had ambitious moon mission plan before long time ago but it had implemented since 2003.
