''Mars mission is a publicity stunt'': Madhavan Nair

Bangalore, Jul 24: India's 'Moon Man' has contested ISRO's contention that the upcoming 'desi' Mars orbiter mission would undertake meaningful research, and dubbed the Rs 450 crore venture as a "publicity stunt".

"ISRO is embarking on an extravagant mission which at best can serve as a publicity stunt", G Madhavan Nair, a former chief of the Bangalore-headquartered Indian Space Research Organisation, told PTI here.

The country was facing an acute shortage of communication transporters, noted Nair during whose tenure of six years as ISRO Chairman and Secretary in the Department of Space, 25 successful space missions were accomplished, including India's maiden moon venture Chandrayaan-I.

ISRO should have solved this issue by following the K Kasturirangan Committee recommendation, he argued.

"Even if the launch takes place, it will be yet another PSLV launch only. One has to wait nearly eight months before anything of MARS is heard. This is an issue which needs a serious review by the scientific community", Nair said.

According to him, GSLV was the vehicle identified because it could take a respectable satellite of nearly 1,800 kg. This could have provided more than a dozen instruments on board and the spacecraft would have been placed in a near circular orbit for a meaningful remote sensing mission of Mars.

"But what is the fate of the much hyped Mars Orbiter Mission (ISRO's mars mission as conceived now) - there were delays in solving the problems of GSLV so a study was undertaken see what can be done with PSLV. Nearly 1500 kg satellite can be taken to Mars, but due to fuel limitation it could at best be placed in an elliptical orbit of 380 km perigee and 80000 km apogee. No one would attempt a resource survey or mapping mission with such widely varying altitudes", Nair said.

ISRO Chairman K Radhakrishnan told PTI recently the Mars mission would undertaken meaningful research.

The primary objectives of the mission, according to ISRO, are to demonstrate India's technological capability to send a satellite to orbit around Mars and conduct meaningful experiments such as looking for signs of life, take pictures of the red planet and study Martian environment.

ISRO is going to start in August first week the assembly of PSLV-C25, the rocket on board of which the Mars orbiter would be launched any day between October 21 and November 7.

Elaborating further, Nair said though there was an initial estimate of 25 kg for the scientific instruments, on detailed analysis provision it was reduced to a meagre 14 kg.

This may further come down.

As it stands today, there could be just five instruments -- a Mars Colour camera (MCC) to take pictures of Mars; Mass Methane Sensor (MMS) to study the amount and origin of Methane on Mars; Lyman Alpha Photometer (LAP), to study the ratio of Hydrogen and Deuterium on Mars; Mars Exosphere Neutral Composition Analyser (MENCA), to study Martian atmosphere AND Thermal Infrared Imaging Spectrometer (TIS).

"Constraints on mass are likely to reduce these payloads," he said.  "With such skeletal instruments on board a spacecraft travelling at altitudes varying from 380 and 80,000 km what meaningful science can be done is a big question mark. This is exactly a case of cutting the head to suit the hat," he contended.

Nair said in Chandrayaan-I when the number of instruments had to be increased, the propulsive power of PSLV was enhanced whereas for Mars Orbiter Mission the desired rocket was not available and the spacecraft was curtailed to an insignificant size.

"Not only that, many of the sub-systems of (the proposed) Chandrayan-2 were cannibalised for the Mars Mission delaying the more meaningful Chandrayan-2.

Chandrayan-2 may take place in 2016 or beyond. China is going with similar mission to moon later this year, not to Mars," he said.

"Mission to Mars is claimed to be complex and challenging. No one familiar with orbital mechanics will appreciate this. The sequence for Mars Mission is identical from the earth's orbit. It will be catapulted on path which will reach near moon or Mars. It may take five days to Moon and eight months to Mars because of the long distance. One has to wait and watch and nothing significant needs to be done during this long wait."

New Delhi, Jan 22: The BJP on Wednesday cited statements of several opposition leaders to accuse them of "abusing" Hindus for their appeasement politics and referred to the Congress as "Muslim League Congress".

Seeking apologies from Congress president Sonia Gandhi and NCP chief Sharad Pawar, BJP spokesperson Sambit Patra said leaders of these parties have used the ongoing protests against the amended citizenship law to "abuse" Hindus.

Chavan has said in a public meeting that the Congress decided to join hands with the Shiv Sena to form government in Maharashtra as Muslims wanted the party to stop the BJP, Patra stated, claiming that it shows the opposition party has nothing to do with people belonging to other religions, including Hindus.

Patra also referred to a statement from an NCP leader to attack the opposition.

Asked about Congress leader Mallikarjun Kharge's reported jibe at the RSS for its "non-participation" in the freedom movement, the BJP leader shot back, asking if parents of Sonia Gandhi, who is of Italian origin, had fought in India's independence struggle.

The Indian National Congress, he said referring to the opposition party's full name, should be called "Muslim League Congress".

New Delhi, Feb 14: AAP convenor Arvind Kejriwal has invited Prime Minister Narendra Modi to his swearing-in ceremony scheduled to take place at the Ramlila Maidan on February 16, senior party leader Gopal Rai said on Friday.

Rai, the convenor of the Aam Aadmi Party's Delhi unit, said a letter was sent to the prime minister on Friday morning.

All seven Delhi MPs and eight newly-elected BJP MLAs have also been invited for the oath-taking ceremony, Rai told news agency.

No chief minister or political leaders from other states will be part of the event as it will be a "Delhi-specific" ceremony, Rai had said on Thursday.

Kejriwal, through front-page advertisements in newspapers, has urged Delhiites to attend his oath-taking ceremony as he is set to become the chief minister of Delhi for the third consecutive term.

Kejriwal will take oath as Delhi Chief minister along with his cabinet at Ramlila Maidan at 10 am on Sunday.

New Delhi, Jan 24: Although India's Ujjwala programme encouraged adoption of liquefied petroleum gas (LPG) for cooking among the poor, households availing the scheme have not shifted away from using highly polluting fuels like firewood, a study reveals.

The researchers, including those from the University of British Columbia (UBC) in Canada, found that additional incentives to encourage regular use of cooking gas are necessary for a complete transition to clean cooking fuel among poor rural households.

They noted that about 2.9 billion people across Asia, Africa, and Latin America burn solid fuels like firewood to meet their cooking energy needs.

This has significant negative implications for public health, the environment, and societal development, according to the researchers.

Through the Pradhan Mantri Ujjwala Yojana (PMUY), India has provided capital cost subsidies to poor women to adopt a clean-burning cooking fuel or LPG.

The researchers explained that within the first 40 months of the scheme, more than 80 million households obtained LPG stoves.

However, the full benefits of LPG adoption depend on near complete replacement of polluting fuels with LPG, according to a research-based policy brief published in the journal Nature Energy.

The scientists said this cannot be assumed solely on the basis of LPG presence in the household.

"Our research shows that Ujjwala was able to attract new consumers rapidly, but those consumers did not start using LPG on a regular basis," Abhishek Kar, a postdoc at Columbia University in the US, told PTI.

The study analysed LPG sales data for over 25,000 consumers, including PMUY beneficiaries, as well as general rural LPG consumers in Koppal district of Karnataka.

The scientists employed data covering all LPG purchases of PMUY beneficiaries through their first year in the programme.

They also assessed the general rural population's purchases during their first five years as consumers to assess the effect of experience on use.

The findings estimate that an average rural family needs to purchase five 14.2 kilogramme-cylinders annually to meet half of their cooking needs.

However, the study said just seven per cent of PMUY beneficiaries in Koppal purchased five or more cylinders annually, suggesting that the beneficiaries seldom use LPG.

The general (nonPMUY) consumers in this region use on average two times more LPG cylinders than PMUY beneficiaries, the researchers noted.

Yet, only 45 per cent of nonPMUY consumers use five or more cylinders per year -- even after several years of experience with LPG, they said.

The team assessed price and seasonal factors affecting LPG use among the general population over a three-year period.

It found that LPG consumers are sensitive to price and seasonality -- LPG cylinder refill rates are lower in the summer when agricultural activity is limited, and cash is scarce.

"There was no scheme incentives to promote use, except general LPG subsidies which is available to all, including the urban middle class," said Kar, who was a Ph.D. scholar at UBC when the research was published.

"If there is no additional income, what cost would a poor family on an already tight budget cut to pay for an extra expense on a regular basis.

"Ujjwala has started the scheme of 5 kg-cylinder in response, but the impact of that on LPG sales is still publicly unknown," he said.

These findings, the researchers noted, suggest the need for additional measures to promote regular LPG use for all rural populations.

Although the finding come from a single district in Southern India, it may also apply to other areas with similar socio-economic conditions, they said.

A more expansive evaluation of PMUY would help design targeted incentives to transform infrequent users to regular users, according to the researchers.
