ASTITVA Issue: X October 2014 To all members of CURAJ family 2 DIWALI iwali also known as Deepavali and the "festival of lights", is an ancient Hindu festival celebrated in autumn every year. The festival spiritually signifies the victory of light over darkness, knowledge over ignorance, good over evil, and hope over despair. The festival preparations and rituals typically extend over a five day period, but the main festival night of Diwali coincides with the darkest, new moon night of the Hindu Lunisolar month Kartika. In the Gregorian calendar, Diwali night falls between mid-October and mid-November. Before Diwali night, people clean, renovate and decorate their homes. On Diwali night, Hindus dress up in new clothes or their best outfit, light up diyas (lamps and candles) inside and outside their home, participate in family puja typically to Lakshmi - the goddess of wealth and prosperity. After puja (prayers), fireworks follow,then a family feast includingmithai (sweets), and an exchange of gifts between family members and close friends. Diwali also marks a major shopping period in nations where it is celebrated. Diwali is an important festival for Hindus. The name of festive days as well as the rituals of Diwali vary significantly among Hindus, based on the region of India. In many parts of India, the festivities start with Dhanteras, followed by Naraka Chaturdasi on second day, Diwali on the third day, Diwali Padva dedicated to wifehusband relationship on the fourth day, and festivities end with Bhau-beej dedicated to sister-brother bond on the fifth day.Dhanteras usually falls eighteen days after Dussehra. On the same night that Hindus celebrate Diwali, Jains celebrate a festival of lights to mark the attainment of moksha by Mahavira, and Sikhs celebrate Bandi Chhor Divas. 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, and Sikhs to mark historical events, stories or myths, but they all spiritually mark the victory of light over darkness, knowledge over ignorance, good over evil, hope over despair. In the Yoga, Vedanta, and Samkhya schools of Hindu philosophy, a central belief is that there is something beyond the physical body and mind which is pure, infinite, and eternal, called the Atman. The celebration of Diwali as the "victory of good over evil", refers to the light of higher knowledge dispelling all ignorance, the ignorance that masks one's true nature, not as the body, but as the unchanging, infinite,immanent and transcendent reality. With this awakening comes compassion and the awareness of the oneness of all things, and knowledge overcomes ignorance. Diwali is the celebration of this Inner Light over spiritual darkness, knowledge over ignorance, right over wrong, good over evil. 3 ‘ ’ I Sem dsanz ljdkj dh rjQ ls fn, x, funsZ”k dk ikyu djrs gq, jktLFkku d¢Unzh¸k fo|kYk¸k esa 2 vDVwcj dks lqcg 9%30 cts ls lQkà vÇÒ¸kku dh “kq#vkr dh xbZ A bLk volj ij lh ;w jkt ds dqyiÇr v©j lÒh f”k{kd deZpkjh v©j fo|kFkÊ mIkfLFkRk FksaA bl vfÒ¸kku dh “kq:vkr dqYkifRk us iwjs tks“k ds lkFk fd;kA mUgksaus us dgk fd ;g dsoy ,d fnu dh ckr ugha gS gesa ;g lQkbZ ges“kk gh djuh gksxhA ogka mifLFkr fo|kfFkZ;ksa us ;g izfrKk Hkh yh fd ge gesa“kk vius vkl&ikl dh lQkbZ j[ksaxs vkSj ,slk ekgkSy cuk nsaxs fd yksx lQkbZ djus ds fy, [kqn c [kqn izsfjr gks tk;saxAs ogka mifLFkr] dYpj ,oa ehfM;k foHkkx ds fo|kFkhZ vfHkeU;q us dgk fd LoPN “kjhj esa gh LoPN eu dk okl gksrk gSA blfy, gesa vius ru dh lQkbZ ds fy, eu dh lQkbZ Hkh j[kuh gksxhA vxj ge nhikoyh ioZ dh ckr Hkh djsa rks Hkh bl ioZ esa lcls vf/kd egRrk lQkbZ dh gSA bl ioZ esa ge ?kj dk dksuk&dksuk lkQ djrs gSa rkfd gekjs ?kj esa y{eh dk okl gksA lgh ek;uksa esa rks bldk vFkZ ;g gS fd LoPNrk gh /ku gSA In every aspect of life, purity and holiness, cleanliness and refinement, exalt the human condition . . .

It is also known as’ Deepawali’. It is celebrated in our country which joy and happiness every year. It is one of the biggest festival of Hindus. Usually it comes in the month of October and November after twenty days of Dussehra, on the 13th day of the dark fortnight of the month of Ashwin. It is celebrated in the memory of coming back home of Lord Rama along with his wife Sita & brother Laxman after 14 years of exile. It is believed that on this day, Lord Rama returned to his kingdom, Ayodhya, after killing the demon, King Ravana and people lighted earthen diyas all around their house and celebrated his victory over Raavan. It is asymbol of victory of good over evil. Since then, the festival is celebrated by lighting diyas and candles to drive away the darkness of Amavasya and the dark of ignorance. Homes are decorated on the day of diwali and sweets are distributed. Laxmi Puja is performed in the evening and blessings of Goddess of Wealth is seeked. People present diwali gifts to their near and dear ones. Earlier, it was celebrated with diyas but slowly it took the form of lights, lighting lamps, candles and crackers. Now a days, people burn dangerous fire crackers limitlessly. Crackers have big hand in polluting our environment. The toxic substances used in the firecrackers release toxic gases that are harmful to the health of all living beings. The noise of the crackers cause immense suffering to birds and animals. Diwali is the festival of lights and not burning of the limitless crackers which takes the form of air and noise pollution. We should minimize the use of firecrackers during diwali celebrations and other celebrations. Noiseless diwali has become the concept for the last few years. It is slowly gathering momentum too. But it has not yet reached that level to which we all can say that yes, we celebrated a noiseless safe and pollution free diwali. A festival must be treated like a festival not like enjoyment or nuisance. There is no need to pollute the environment for this. We must take steps to make ourselves and others aware to put an end to noise through rallies and hoardings. We must not buy unlimited crackers instead of that we can help a poor with that money. These days, trend of diwali greetings, diwali messages, diwali cards, diwali ecards, diwali calendar, diwali greeting cards, diwali flash,diwali themes, diwali screensaver, diwali images, diwali rangoli, diwali scraps, diwali designs, diwali painting is going on. It seems and feels very nice to wish each other by different means. But we must also make each other aware of the harms of the pollution caused by the firecrackers that leads directly or indirectly to global warming. Hence, Say ‘NO’ to Crackers and play a safe, noiseless and pollution free Diwali. 5 Anurag Verma, III Sem 6 ‘ ’ ‘ ’, PhD Scholar, CMS tkus fdrus fQYeh jhyksa dks csdkj djus ds ckn fp=iV ij ,d ÞxkbZMß mrjk gksxk, ftlus nsokuan dks egt dksbZ uk;d ;k fdjnkj u j[k dj ,d fdEonUrh cuk fn;k A fQYe dk eq[; fdjnkj ,d vke balku gksdj Hkh egkuk;d cu tkrk gS vkSj dgkuh fQYeh gksdj Hkh thou n'kZu dh rjg fn[krh gS A nsonklh dh csVh] BqdjkbZ gqbZ C;kgrk dks çJ; nsdj lkekftd dqjhfr;ksa ls vk¡[ks feykus okyk galrk [ksyrk gqvk eLrekSyk ckadk ukStoku vpkud gh çkS<+ vkSj vlk/kkj.k lk fn[kus yxrk gS A dgkuh ;gha [kRe ugha gksrh ---- ;g rks balku ds bZ'oj cuus dh xkFkk gS ftlesa nsoRo ls igys ,d euq"; dk ,d euq"; ds :i mRFkku vkSj iru nksuks gSa A gokvksa lax ckrsa djrk viuh eu ethZ dk ekfyd jktw xkbZM rks iSjksa esa ca/kh gqbZ csfM+;ksa ds lkFk ykpkj gj jkst ?kqVrh gqbZ jksth A t:jrean dh enn djuk---fdlh dk lkFkh cu mlds liuks¡ dks gdhdr esa cnyuk tgka ekuoh; ewY;ksa ds mR—"Vrk dk iSekuk gS rks ogh¡ bldk cstk Qk;nk mBkuk] ;su & dsu çdjs.k ml viuk gd tek;s j[kus dh dksf'k'k djuk iru dh ijkdk"Bk, jktw ftUnxh ds bu nksuksa igyqvksa dks oä ds lkFk thrk gS A xkbZM dk gj ,d Ýse gjsd –'; fdlh 'kkL=h; laxhr dh jkfxuh tSlh gS] tks n'kZdksa dks vkfRed vkuan dk vglkl fnykrh gS A var esa nqfu;koh vuqHkoksa ls nhf{kr gks pqds jktw ds fy, u dksbZ nhu gS u dksbZ nqfu;k u fdlh dks pkgrs jgus dk lq:j u gh fdlh dks ftrk nsus dk xq#j A Hkys gh og nks od~r dh jksVh dh lqfo/kk dks ns[krs gq, egkRek cus jgus ds Lokax jprk gS ijUrq bl vfHku; esa ikgh Hkkoukvksa dh ckfj'k esa l{ke gS A rks vkb, fey dj xqtkfj'k jaxrrk dh iw.kkZgqfr varr% mls vius çk.kksa dks Lokg% dj ds nsuh djs--- jkek es?k ns, es?k ns js, vks vYykg es?k ns js, ';kek es?k ns gksrh gS A vkt laosnukvksa dh lq[kkM+ ds bl nkSj esa dksbZ ,slk xkbZM es?k ns es?k ns js ------ A 7 Anurag Verma, III Sem 8 Entrepreneur in Action epartment of Economics and Economic Society have successfully organized the event “Entrepreneur in Action” on October 16th 2014.

On 24 September 2014, Indian Space Research Organisation (ISRO) successfully placed Mars Orbiter Mission (MOM) spacecraft, also known as Mangalyaan, in the orbit of Mars. MOM is an orbiter craft designed to orbit Artist's rendering of the Mangalyaan Mars in an elliptical orbit. For the orbiting Mars next six to ten months, MOM will (Source Wikipedia) remain a satellite of Mars, click pictures and sniff out details on the atmosphere and morphology of the red planet. India is the first country to reach Mars’s orbit on a maiden venture, and the first Asian country to launch a successful Mars mission, all with much less expenditure than any other Mars mission before it. MOM is India's first interplanetary mission and ISRO has become the fourth space agency in the world to reach Mars, after the Russian Federal Space Agency (ROSCOSMOS), US space agency NASA, and the European Space The ISRO’s Mars Orbiter captured this global view of Mars with its Mars Colour Camera on 28 September 2014, from a distance of 74,500 kilometres [Source: ISRO] The Mars Orbiter will be able to capture full-globe views when it is near the apoapsis of its orbit (farthest from the surface). The spacecraft will spend most of its time near apoapsis. As a result, the Mars Orbiter will be able to capture a series of global views of Mars at different phases and of different parts of the planet over time. Agency (ESA). Before ISRO, only the European Space Agency could place its orbiter right in the first attempt (‘Mars Express’ in 2003). However, India can claim to be the first country to achieve the distinction, as the European Space Agency is a conglomeration of several countries. Japan and China are the other Asian countries that had attempted Mars missions, but failed. Accomplished at a cost of around Rs 450 crore, which in itself is an achievement as the most economical interplanetary space mission till date, the Mars Orbiter Mission is an ambitious leap forward for India’s space programme. After its launch on 5 November 2013, Mangalyaan has travelled over 670 million kilometres (radio distance is 210 million kilometres) between Earth and the red planet during its 300 days’ journey. A number of manoeuvring was done by ISRO scientists to ensure successful insertion of the orbiter into Mars orbit. ISRO’s Mars Orbiter took this photo of the hazy limb of Mars on 24 September 2014, just two hours after entering orbit, from an altitude of about 8,449 kilometres.

Journey to Mars It was in 2008 when ISRO launched its first Moon mission Chandrayaan-1. The Mars mission was conceptualised during this time. A feasibility study was conducted in 2010 and subsequently the project was approved by Government of India. Scientists from ISRO, Physical Research Laboratory (PRL), and Hindustan Aeronautics Limited (HAL) took about 15 months for the design and construction of the spacecraft and preparation of the launch vehicle, aiming for a target launch date of 28 October 2013. The launch date was calculated to meet the trans-Mars injection requirements needed to place the Mars Orbiter into the correct heliocentric Mars transfer orbit. Scientists of ISRO calculated the manoeuvring sequence and procedure of the orbiter based on the location of the launch, the orbital insertion parameters at Mars, resource availability in the spacecraft, the orbital positions of Earth and Mars at the time of the Mars Orbiter’s arrival at the gravitational sphere of influence of Mars and many other factors.

Cruise to Mars After leaving Earth orbit, a total of three trajectory course manoeuvres were performed to ensure that the Mars Orbiter is aligned into the proper trajectory for arrival at Mars. On 22 September 2014 at 14:30 hrs IST, spacecraft controllers successfully fired the 440N liquid apogee motor for 3.9 seconds. The test firing confirmed the engine’s viability for 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 the craft’s line of travel. Once in the proper orientation, the orbiter, already under the influence of Mars’s gravity, passed into the shadow of Mars. This entry into the Martian shadow occurred five minutes before the start of the Mars Orbit Insertion (MOI) burn. As the MOI burn began, Mars Orbiter’s main liquid engine and eight smaller thrusters fired to begin reducing the vehicle’s velocity to 1,098.7 metres per second. ....Next page 17 A giant interplanetary leap to Mars... As this burn began, the spacecraft moved behind Mars as viewed from the telemetry and tracking stations on Earth, thereby severing the radio communications link between the spacecraft and ground controllers. The duration of the mission-critical MOI burn occurred while communications with the spacecraft were blocked. After the MOI burn Once the MOI burn was completed, the spacecraft began reorienting itself to point its main communications antenna toward the location where Earth will be when the spacecraft emerged from the communications blackout period. With MOI burn successfully accomplished, the Mars Orbiter entered a highly elliptical orbit around the red planet at 07:30 IST on 24 September 2014, marking the success of the first Indian interplanetary mission. International cutting edge Despite being a technology demonstration, the MOM will morph into a truly scientific mission as it carries five sophisticated equipment. The Mars Colour Camera (MCC) is the "eye of the mission", meant to capture images and information about the surface features and composition of the Mars. MCC has already captured and sent back global view and detailed views of Mars. The global scientific community is very excited about India's effort to send the first dedicated methane gas sensor to Mars. The presence of methane gas, also called "marsh gas", on Earth is one of the clinching signs of the presence of carbonbased life forms. Findings of ISRO’s Mars Orbiter will be vital in supplementing the findings of MAVEN and other spacecraft orbiting Mars and surface rovers like Curiosity and Opportunity. With new data, global scientific community would be one step closer in unfolding the mystery of the red planet. Through spearheading cutting edge technology demonstration like MOM, ISRO has once again proved the science and technology capability of India. Way ahead ISRO can now look forward with confidence to its other future missions the second Moon mission - Chandrayaan-2 that is to land a rover on the Moon's surface, possibly in 2017; launching Aditya-1 a spacecraft to study the Sun; and the ambition of putting Indians in Earth orbit as part of its Human Spaceflight Programme. 18 Happy Diwali by ASTITVA Editorial Team
