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.

Is Diwali the Festival of
Lights Or Crackers?
Rajesh Anchara, III Sem
Diwali is the festival of lights. 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.

A giant interplanetary leap to Mars

India created history on its maiden attempt in an interplanetary mission. On 24 September 2014, Indian Space Research Organisation (ISRO) successfully placed Mars

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

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.

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.

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.

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.
