LAUNCHING OF MANGALYAAN
Mangalyaan is a space mission of isro.The mission was carried under the guidance of Dr.mylswamy
annadurai.Mangalyaan was launched from satish dhawan space center,
sriharihota,andrapradesh.It is launched by using polar statellite launch vehicle
PSLV-C25 on 5 november 2013.It spent a month in geo-centric, lower earth orbit and then
injected to the orbit of mars on 24 september 2014.The mission is a technology administrator to develop technology
for inter-planetary mission. The total cost is about 454 crore($74million).
MISSION OBJECTIVESThe primary objective included the task ofDesign and realisation of mars orbiter with a capability o perform earth-bound manoeuvres,cruise phase of 300 days, mars orbit insertion/ capture and on orbit phase around mars.Deep-space communication,navigation,mission planning and management.Incorporate autonomous features to handle cotingency situations .The secondary objective is to explore mars surface features,morphology,mineralogy and martian atmosphere.
PAYLOADSMangalyaan consist of 15kg scientific payload
consist of five instruments.PAYLOADS

STUDIES
ATMOSPHERIC STUDIESLYMAN-ALPHA PHOTOMETER
Lyman alpha photometer(LAP) is a photometer is an absorption cell photometer.
It measures the relative abundance of deuterium and hydrogen from Lyman-alpha emission in the Martian upper atmosphere
(typically Exosphere and exobase). Measurement of D/H (Deuterium to Hydrogen
abundance Ratio) allows us to understand especially the loss process of water from
planet.
METHANE SENSOR FOR MARS(MSM)MSM is designed to measure Methane (CH4) in
the Martian atmosphere with PPB accuracy and map its sources.
Data is acquired only over illuminated scene as the sensor measures reflected solar radiation.
Methane concentration in the Martian atmosphere undergoes spatial and temporal
variations. Hence global data is collected during every orbit.
PARTICLE ENVIRONMENT STUDIESMARS EXOSPHERIC NEUTRAL
COMPOSITION ANALYSERMENCA is a quadruple mass spectrometer capable of analysing the neutral composition in the range of 1 to 300 amu with unit mass resolution in the exosphere. The heritage of this payload is from Chandrayaan’s Altitudinal Composition Explorer (CHANCE) payload aboard the Moon Impact Probe (MIP) in Chandrayan-1 mission.
SURFACE IMAGING STUDIESTHERMAL INFRARED IMAGING
SPECTROMETER(TIS)TIS measure the thermal emission and can be
operated during both day and night. Temperature and emissivity are the two basic physical parameters estimated from thermal
emission measurement. Many minerals and soil types have characteristic
spectra in TIR region. TIS can map surface composition and mineralogy
of Mars.
MARS COLOUR CAMERA(MCC)
This tri-colour Mars Colour camera gives images & information about the surface features and composition of Martian surface. They are useful to monitor the dynamic events and weather of Mars. MCC will also be used for probing the two satellites of Mars – Phobos & Deimos. It also provides the context information for other science payloads
CURRENT STATUS OF MANGALYAAN
The spacecraft is being monitored from the spacecraft control centre at ISRO TELEMETRY,TRACKING AND COMMAND NETWORK(ISTRAC) in bangalore with
support from INDIAN DEEP SPACE NETWORK(ISDN).The mangalyaan has successfully completed its six
months in the mars orbit.According to the ISRO news report march 24,2015-the
mission has extended up to another six months because of the statellite has 37 kilograms fuel left,which can easily
help it to lies in the mars orbit.
AWARDSISRO’s mars mission team has won the
prestigious award 2015 space pioneer award in the science and engineering category.
The award was given by national space society during the national space society’s 2015
international space development conference to be held in toronto from may20-24.
