iwali also known as Deepavali and the"festival of lights", is an ancient Hindu fes-tival celebrated in autumn every year. Thefestival spiritually signifies the victory oflight over darkness, knowledge over igno-rance, good over evil, and hope over de-spair. The festival preparations and ritualstypically extend over a five day period, butthe main festival night of Diwali coincideswith the darkest, new moon night of theHindu Lunisolar month Kartika. In theGregorian calendar, Diwali night falls be-tween mid-October and mid-November.Before Diwali night, people clean, reno-vate and decorate their homes. On Diwalinight, Hindus dress up in new clothes ortheir best outfit, light up diyas (lamps andcandles) inside and outside their home,participate in family puja typically to Lak-shmi - the goddess of wealth and prosper-ity. After puja (prayers), fireworksfollow,then a family feast includingmithai(sweets), and an exchange of gifts betweenfamily members and close friends. Diwalialso marks a major shopping period in na-tions where it is celebrated.Diwali is an important festival for Hindus.The name of festive days as well as the rit-uals of Diwali vary significantly amongHindus, based on the region of India. Inmany parts of India, the festivities startwith Dhanteras, followed by NarakaChaturdasi on second day, Diwali on thethird day, Diwali Padva dedicated to wife-husband relationship on the fourth day, andfestivities end with Bhau-beej dedicated to

sister-brother bond on the fifthday.Dhanteras usually falls eighteen daysafter Dussehra.On the same night that Hindus celebrateDiwali, Jains celebrate a festival of lightsto mark the attainment of moksha by Ma-havira, and Sikhs celebrate Bandi ChhorDivas.Diwali is an official holiday in India,Nepal, Sri Lanka, Myanmar, Mauritius,Guyana, Trinidad and Tobago, Suriname,Malaysia, Singapore and Fiji.Diwali is celebrated by Hindus, Jains, andSikhs to mark historical events, stories ormyths, but they all spiritually mark the vic-tory of light over darkness, knowledgeover ignorance, good over evil, hope overdespair. In the Yoga, Vedanta, and Samkhyaschools of Hindu philosophy, a central be-lief is that there is something beyond thephysical body and mind which is pure, in-finite, and eternal, called the Atman. Thecelebration of Diwali as the "victory ofgood over evil", refers to the light of higherknowledge dispelling all ignorance, the ig-norance that masks one's true nature, not asthe body, but as the unchanging,infinite,immanent and transcendent reality.With this awakening comes compassionand the awareness of the oneness of allthings, and knowledge overcomes igno-rance. Diwali is the celebration of thisInner Light over spiritual darkness, knowl-edge over ignorance, right over wrong,good over evil.

Diwali is the festival of lights. It is also knownas’ Deepawali’. It is celebrated in our countrywhich joy and happiness every year. It is one ofthe biggest festival of Hindus. Usually it comes

in the month of October and November aftertwenty days of Dussehra, on the 13th day of thedark fortnight of the month of Ashwin. It is cel-ebrated in the memory of coming back home ofLord Rama along with his wife Sita & brotherLaxman after 14 years of exile. It is believedthat on this day, Lord Rama returned to his king-dom, Ayodhya, after killing the demon, KingRavana and people lighted earthen

diyas all around their house andcelebrated his victory over Raa-van. It is asymbol of vic-tory of good over evil.Since then, the festi-val is celebratedby lighting diyasand candles todrive away thedarkness ofAmavasya and the

dark of ignorance.Homes are deco-rated on the day ofdiwali and sweetsare distributed.Laxmi Puja is per-formed in the evening and blessings of Goddessof Wealth is seeked. People present diwali giftsto their near and dear ones. Earlier, it was cele-brated with diyas but slowly it took the form oflights, lighting lamps, candles and crackers.Now a days, people burn dangerous fire crack-

ers limitlessly. Crackers have big hand in pollut-ing our environment. The toxic substances usedin the firecrackers release toxic gases that areharmful to the health of all living beings. The

noise of the crackers cause immense suffering tobirds and animals. Diwali is the festival of lightsand not burning of the limitless crackers whichtakes the form of air and noise pollution. Weshould minimize the use of firecrackers duringdiwali celebrations and other celebrations. Noise-less diwali has become the concept for the lastfew years. It is slowly gathering momentum too.But it has not yet reached that level to which weall can say that yes, we celebrated a noiselesssafe and pollution free diwali. A festival must betreated like a festival not like enjoyment or nui-

sance. There is no need to pollute the envi-ronment for this.

We must take stepsto make ourselves and

others aware to put an endto noise throughrallies and hoard-ings. We must notbuy unlimitedcrackers instead ofthat we can help a

poor with thatmoney. These days,trend of diwali

greetings, diwalimessages, diwalicards, diwali

ecards, diwali calen-dar, diwali greeting cards, diwali flash,diwalithemes, diwali screensaver, diwali images, diwalirangoli, diwali scraps, diwali designs, diwalipainting is going on. It seems and feels very niceto wish each other by different means. But wemust also make each other aware of the harms ofthe pollution caused by the firecrackers that leadsdirectly or indirectly to global warming. Hence,Say ‘NO’ to Crackers and play a safe, noiselessand pollution free Diwali.

Is Diwali the Festival ofLights Or Crackers?

A giant interplanetary leap to MarsRintu Nath

India created history on its maiden attempt in an interplan-etary mission. On 24 September 2014, Indian Space Re-search Organisation (ISRO) successfully placed MarsOrbiter Mission (MOM) spacecraft, also known as Man-galyaan, in the orbit of Mars. MOMis an orbiter craft designed to orbitMars in an elliptical orbit. For thenext six to ten months, MOM willremain a satellite of Mars, click pic-tures and sniff out details on the at-mosphere and morphology of thered planet. India is the first country to reachMars’s orbit on a maiden venture,and the first Asian country to launcha successful Mars mission, all with much less expenditurethan any other Mars mission before it.MOM is India's first interplanetary mission and ISRO hasbecome the fourth space agency in the world to reachMars, after the Russian Federal Space Agency (ROSCOS-MOS), US space agency NASA, and the European Space

Agency (ESA). Before ISRO, only the European SpaceAgency could place its orbiter right in the first attempt(‘Mars Express’ in 2003). However, India can claim to bethe first country to achieve the distinction, as the European

Space Agency is a conglomeration ofseveral countries. Japan and Chinaare the other Asian countries that hadattempted Mars missions, but failed.Accomplished at a cost of around Rs450 crore, which in itself is anachievement as the most economicalinterplanetary space mission till date,the Mars Orbiter Mission is an am-bitious leap forward for India’s spaceprogramme.

After its launch on 5 November 2013, Mangalyaan hastravelled over 670 million kilometres (radio distance is210 million kilometres) between Earth and the red planetduring its 300 days’ journey. A number of manoeuvringwas done by ISRO scientists to ensure successful insertionof the orbiter into Mars orbit.

The Mars Orbiter will be ableto capture full-globe views whenit is near the apoapsis of its orbit(farthest from the surface). Thespacecraft will spend most of its time near apoapsis. As a re-sult, the Mars Orbiter will be able to capture a series ofglobal views of Mars at different phases and of differentparts of the planet over time.

When the spacecraft is closer to Mars, it will be able to capture detailed viewof a part of the planet’s surface.

As it goes around Mars in a highly elliptical orbit, with theclosest point of around 420 km and the farthest of around80,000 km, the Mars Orbiter will employ five instruments todo scientific studies like exploration of surface features, mor-phology, and mineralogy and studyof Martian atmosphere.Interestingly, only three days beforeISRO’s Mangalyaan arrived atMars, on 21 September, NASA’sMAVEN (Mars Atmosphere andVolatile Evolution) spacecraft suc-cessfully entered Mars’ orbit. BothMangalyaan and MAVEN will sup-plement each other in solving themystery of Mars’ missing water. While on the ground, Curiosity - NASA’s robotic rover con-tinues to search for local evidence of past and present water,MAVEN’s investigation, along with those of Mangalyaan,will provide necessary data to scientists for better understand-ing of the planet. Together, these missions could reveal theentire planet’s geological history. Mission objectivesMars Orbiter Mission is India's first interplanetary mission toplanet Mars with an orbiter craft designed to orbit Mars. Themission is designed to demonstrate India’s capability to per-

form deep space communication, navigation, mission plan-ning, and management; and incorporate autonomous featuresto categorise and handle contingency situations. Although the mission is primarily a technological mission, it

has a number of scientific objectives likeexploration of Mars’ surface features,morphology, mineralogy and its atmos-phere.The Mars Orbiter carries five sci-entific payloads to observe Martiansurface, atmosphere and exosphere ex-tending up to 80,000 km for a detailedunderstanding of the evolution of theplanet, especially the related geologicand the possible biogenic processes. Thepayloads consist of a camera (Mars

Colour Camera), two spectrometers, a radiometer, and a pho-tometer. Together, they have a weight of about 15 kg.Considering the critical mission operations and stringent re-quirements for spacecraft navigation to put the orbiter in grav-itational sphere of influence of Mars, ISRO has alreadyachieved the technological objective. While writing this article, four out of five instruments havealready been activated. Mars Colour Camera (MCM) has cap-tured and sent back breathtaking views of Mars. The imagesreturned from the Mars Orbiter are truly captivating.

It was in 2008 when ISRO launched its first Moon missionChandrayaan-1. The Mars mission was conceptualised dur-ing this time. A feasibility study was conducted in 2010 andsubsequently the project was approved by Government ofIndia. Scientists from ISRO, Physical Research Laboratory (PRL),and Hindustan Aeronautics Limited (HAL) took about 15months for the design and construction of the spacecraft andpreparation of the launch vehicle, aiming for a target launch

date of 28 October 2013. The launch date was calculated tomeet the trans-Mars injection requirements needed to placethe Mars Orbiter into the correct heliocentric Mars transferorbit. Scientists of ISRO calculated the manoeuvring se-quence and procedure of the orbiter based on the location ofthe launch, the orbital insertion parameters at Mars, resourceavailability in the spacecraft, the orbital positions of Earthand Mars at the time of the Mars Orbiter’s arrival at the grav-itational sphere of influence of Mars and many other factors.

Construction on the Mars Orbiter was successfully completedon schedule on 2 October 2013, and the spacecraft wasshipped to its launch site in Sriharikota. The orbiter was in-tegrated on top of its PSLV-XL (Polar Satellite Launch Vehi-cle) rocket – which had been under assembly since August2013.The use of the PSLV-XL rocket was a change from the orig-inal mission proposal that recommended the use of the more-powerful Geosynchronous Satellite Launch Vehicle (GSLV).However, the GSLV had failedtwice in 2010 and to find thecause of failure took time. ISROdid not want to take a chance anddecided to use the tried and testedpolar satellite launch vehicle(PSLV). Time of launch was cru-cial. If it could be done sometimein November 2013, less energywould be required to insert theorbiter in the gravitational field ofinfluence of Mars. If launch is de-layed, ISRO would have to waittill 2016 when the next Marslaunch window would open.Therefore ISRO decided to launchthe mission with a PSLV-XLrocket that carried six stretched solid rocket motors using 12tons of solid propellant instead of the 9 tons used in the stan-dard PSLV variant.The switch in launch vehicle, however, meant that MOMcould no longer be launched directly into a Mars transferorbit. Rather, the craft would have to be launched into anelongated Earth orbit, and then perform a series of orbit-rais-ing manoeuvres to raise its apogee while using Earth’s grav-ity to sling-shot it into the correct Mars transfer orbit.As launch preparations continued, MOM’s launch date wasrescheduled from 28 October to 5 November 2013 becauseof the delayed arrival of a necessary telemetry ship at the FijiIslands in the Pacific, which would track the satellite afterlaunch. On 5 November 2013, the orbiter was launched on

time at 14:38 hrs IST from the First Launch Pad at the SatishDhawan Space Centre. Over the next 42 minutes, the PSLV-XL inserted the orbiter into Earth orbit, a process completedat 15:20 hrs IST.The successful launch of the Mars Orbiter Mission markedIndia’s entry into interplanetary space.A series of five planned orbit raising manoeuvres began, con-trolled by engineers at the Spacecraft Control Centre atISRO’s telemetry, tracking and command network in Peenya,

Bangalore.Of the five planned manoeuvres,the first was a 416-second firingof the spacecraft’s liquid engine(LAM), the second a 570.6-sec-ond burn, and the third a 707-sec-ond burn. At this point, the MarsOrbiter’s apogee was 71,636km.During the fourth burn, anunder-burn prevented the space-craft’s apogee from reaching theplanned 1,00,000 km. Instead, theorbiter was in a 78,276-kmapogee orbit. The resulting under-burn mandated the addition of asupplementary orbit raising ma-noeuvre of the orbiter. After this

supplementary orbit raising manoeuvre (starting at 05:03 hrsIST on 12 November 2013, with a burn time of 303.8 sec-onds) height of the apogee was increased from 78,276 kmto 1,18,642 km.The fifth orbit raising manoeuvre of the orbiter took place on16 November 2013, with a burn time of 243.5 seconds.Height of the apogee now increased from 1,18,642 km to1,92,874km.With the needed apogee achieved, spaceflight controllers ini-tiated a 1328.89-second engine firing manoeuvre on 1 De-cember 2013 to place the orbiter into a heliocentric transferorbit towards the red planet. Trans-Mars Injection (TMI) op-eration was completed successfully at 00:30 hrs IST on 1 De-cember 2013.

Cruise to MarsAfter leaving Earth orbit, a total of three trajectory coursemanoeuvres were performed to ensure that the Mars Orbiteris aligned into the proper trajectory for arrival at Mars.On 22 September 2014 at 14:30 hrs IST, spacecraft con-trollers successfully fired the 440N liquid apogee motor for3.9 seconds. The test firing confirmed the engine’s viabilityfor planned orbital insertion operations 41 hours later.Mars Orbital Insertion (MOI)

As the Mars Orbiter approached Mars for orbital insertion,the spacecraft reoriented itself to align its thrust with thecraft’s line of travel. Once in the proper orientation, the or-biter, already under the influence of Mars’s gravity, passedinto the shadow of Mars. This entry into the Martian shadowoccurred five minutes before the start of the Mars Orbit In-sertion (MOI) burn. As the MOI burn began, Mars Orbiter’smain liquid engine and eight smaller thrusters fired to beginreducing the vehicle’s velocity to 1,098.7 metres per second.

As this burn began, the spacecraft moved behind Mars asviewed from the telemetry and tracking stations on Earth,thereby severing the radio communications link between thespacecraft and ground controllers. The duration of the mis-sion-critical MOI burn occurred while communications withthe spacecraft were blocked. After the MOI burnOnce the MOI burn was completed, the spacecraft began re-orienting itself to point its main communications antenna to-ward the location where Earth will be when the spacecraftemerged from the communications blackout period. WithMOI burn successfully accomplished, the Mars Orbiter en-tered a highly elliptical orbit around the red planet at 07:30IST on 24 September 2014, marking the success of the firstIndian interplanetary mission.International cutting edgeDespite being a technology demonstration, the MOM willmorph into a truly scientific mission as it carries five sophis-ticated equipment. The Mars Colour Camera (MCC) is the"eye of the mission", meant to capture images and informa-tion about the surface features and composition of the Mars.

MCC has already captured and sent back global view anddetailed views of Mars.The global scientific community is very excited about India'seffort to send the first dedicated methane gas sensor to Mars.The presence of methane gas, also called "marsh gas", onEarth is one of the clinching signs of the presence of carbon-based life forms. Findings of ISRO’s Mars Orbiter will bevital in supplementing the findings of MAVEN and otherspacecraft orbiting Mars and surface rovers like Curiosityand Opportunity. With new data, global scientific commu-nity would be one step closer in unfolding the mystery of thered planet. Through spearheading cutting edge technologydemonstration like MOM, ISRO has once again proved thescience and technology capability of India. Way aheadISRO can now look forward with confidence to its other fu-ture missions the second Moon mission - Chandrayaan-2 thatis to land a rover on the Moon's surface, possibly in 2017;launching Aditya-1 a spacecraft to study the Sun; and theambition of putting Indians in Earth orbit as part of itsHuman Spaceflight Programme.
