MOM Results from Mars

We all have been eagerly waiting for MOM to bring the scientific wealth from Mars. Except for the few pretty COLOUR images from MCC (Mars Color Camera), the common man in India has almost forgotten MOM (Mars Orbiter Mission). The highly exciting rendezvous with comet Sliding Spring on Mars did not yield any results to the public yet. On the part of NASA, their baby MAVEN (Mars Atmosphere and Volatile EvoultioN) churned out a set of data saying that the incidence indeed pumped an appreciable amount of elements (e.g. Sodium) into the Martian atmosphere. Yesterday evening, my friend Mr. Srinivas Laxman, broke the news that finally a facebook page of ISRO has flashed a color image obtained by MSM (Methane Sensor for Mars) payload. I stopped taking my dinner and rushed to the ISRO site and was excited to see that MOM has indeed climbed the first step in bringing the path breaking science at the door steps of ISRO scientists? Why so... Let me explain...

Please refer to my earlier post on MOM payloads ; here while narrating each instrument, I had also graded them on a 10-point scale system. On this scale, MSM gets a grade of 7, which is next to MENCA getting 8. It is due to the huge impact factor which is, in a way, in the form of bringing answers to the question "Whether Life exists on Mars? " that these 2-instruments stand out as the sole representatives of bringing cutting edge results.

It would be a pleasant music to the ears of Dr. Michael Mumma of NASA's Goddard (GSFC) who has been the pioneer of tracking the methane on Mars by ground based telescopes; while the Indian origin Prof. S.K Atreya, Univ. of Michigan,  a veteran on studying planetary atmospheres would also be very keen to note the same.

Have a look at the image:

Basically it is the reflectance image of Mars collected till Dec. 16th, 2014 at a reference wavelength centred around 1.65 micron.

What does this mean ??? This means a lot ... I am too excited for the following reasons:
1. It means the payload MSM has worked wonderfully well. Unlike its well trusted policy of employing heritage tagged instruments, it is a first time attempt by ISRO in employing a Fabry-Perot etalon based instrument; every thing seems to have worked well... starting from the conceptual stage to the execution of Flight Model. This is like scaling Mt. Everest for an instrument specialist like me.

2. The image quality is excellent, which means the optics, detectors and data acquisition has worked to its optimal efficiency; while the 1.65 micron is the reference channel which measures the nearby background, the characteristic methane band is situated in next vicinity and hence it can be declared that the instrument is fully operational.  The MSM instrument is designed to measure ppb (parts per billion) level of Methane; in a recent news update the CURIOSITY rover has taken a U-turn (compared to a negative outcome for Methane detection) to announce that it has detected a 10-time (ppb level) spike of Methane in its SAM instrument.

3. Last but not the least: It has indeed opened up the skies in hunting down the elusive/episodal  methane, as if MSM is declaring that: Where are you... I am comin....

  1. Nice and significant points..

  2. Thanks for the comment... please do have a look at my earlier post where I had explained and predicted the future for these payloads of MOM.

Mars Orbiter Mission (MOM): Indian Mission for Mars

Introduction:
Come November 3rd week this year, a billion aspirations filled PSLV-XL would be roaring into the skies of Bay of Bengal from a sleepy town of Sriharikota in the Indian state of Andhra Pradesh. It was also mentioned in some occasions (unofficially); as the target is Mangal the planet mars and hence the space craft, yaan in Hindi named Mangalyaan. Nobody had ever thought that when the then Prime Minister Sri Atal Bihari Vajpayee (with a think tank comprising of one of the most popular presidents, Dr. A.P.J. Abdul Kalam) declared that India will aspire to go to the Moon in his inspirational speech from the Red Fort in Delhi on 15th August (2003), it will be a giant leap for the Indian space community and for that matter for every Indian.

What a success it was for Chandrayaan, the maiden Indian attempt to the most lovable heavenly body. India had lined up its space probe (2008) along with SELENE (Japan, 2007), Change (China, 2007) and LRO (USA, 2009). When reaching the moon …

MOM'S MARCH to MARS

Billion hearts were beating harder than the thrust of PSLV-XL which lifted MOM (India's Mars Orbiter Mission) into a  text book like (as ISRO officials call) 247 X 23,500 km orbit. Oh... by the way, the triple M treat continues (as a tradition of this post)... The pulse of the nation can be gauged by 25,000 likes just during the launch (~ 44 minutes), now 187, 000 and the count is ON for the official MOM's FB page ; also the ISRO site getting repeatedly hanged during the launch. The most heartening part of the successful launch in my view is: a bunch of primary school kids appearing in the TV- panel discussion  (mainly girls... another vow.. for the growth of India) were mesmerizing the local people here in this state by explaining each small step taken by MOM and its developers. To put it in president Kalam's words the young minds got ignited; it is indeed a Giant step for the entire nation. The fever of Mars odyssey has gripped the nation; every local newspaper carried …
