ISRO Scientists Discuss Mars, Venus Plans At Cospar 2012
By Srinivas Laxman | Top News
July 23, 2012

ISRO scientists are working hard to launch a mission to Mars, and contemplating its plans for Venus.

ЦитироватьAsianScientist (Jul. 23, 2012) – The Indian Space Research Organization (ISRO) has been bitten by the Red Planet bug!

Scientists at the space agency are working hard to launch a mission to Mars. What better proof of this fact than the fact that ISRO is not waiting for the much-awaited formal approval from the government to start designing the science instruments for this mission?

Engineering models of two of the payloads are ready, and tests are in full progress.

Rajmal Jain of the Ahmedabad-based Physical Research Laboratory, (PRL) an affiliate of ISRO, told Asian Scientist Magazine on Friday that the mechanical structure of the Plasma and Current Pace Experiment (Pace) instrument weighing 2.99 grams is now ready.

The instrument will study the Martian atmosphere and has undergone vibration and other tests at the Space Application Center (SAC) in Ahmedabad. The payload was a joint developed by SAC and PRL.

He said that the work on the flight model will begin soon.

Kurian Mathew of SAC said work was in progress on a payload called the Miniature Electro-Optic Sensor weighing three kilograms, which has a Mars color camera.

    "The engineering model is ready, but we are doing some more tests," he said.

He explained that the total weight of all the Mars-bound payloads was 10.5 kg necessitating the removal of some of the instruments.

If the mission gets approved then it will be launched from Sriharikota in November 2013. The rocket will be the advanced version of the four-stage Polar Satellite Launch Vehicle (PSLV) known as PSLV-XL which was used for the Chandrayaan-1 mission to the moon.

In a session on Venus, Sanjay Limaye of the University of Wisconsin, said "We hope ISRO looks to Venus as a possible target."

Limaye, who has been involved with the Venus mission said that "international co-ordination and collaboration is essential for a systematic exploration of Venus 2018 and beyond."

    "Finding an answer to questions about Venus that are relevant for earth will require us all to work together. Participate and contribute," he told the international community of space scientists.

ЦитироватьИндия собирается покорять Марс[/size]
Сегодня, 10:04              

Индия планирует покорить Марс в следующем году.

Индийские ученые ждут согласия правительства на отправку первой миссии на Марс. После получения разрешения в октябре 2013 года к Марсу стартует индийский межпланетный зонд, который будет изучать планету с орбиты.

Проект находится на последней стадии утверждения и ждет решения о выделении 22,6 миллионов долларов на сборку и запуск аппарата.

Космический аппарат планируют запустить с космодрома на острове Шрихарикота в южном штате Андхра-Прадеш. Запуск будет произведен с помощью индийской ракеты-носителя PSLV.

В настоящее время индийское космическое агентство ISRO работает над улучшением двигателя ракеты. Испытания данного этапа должны быть завершены к ноябрю текущего года.

Космический аппарат будет нести девять научных инструментов, для исследования климата и геологии планеты, ее жизни. К Марсу планируют доставить 25 кг научного оборудования. Зонд выйдет на околомарсианскую орбиту с минимальной высотой 500 км.

Большой объем работы выполнен, новое оборудование планируют сдать в ближайшее время.[/size]

Интересно, на индийский зонд еще можно воткнуть наш прибор, к примеру детектор альбедо нейтронов для поиска воды на Марсе? Да, такой прибор на Одиссее есть, на "Любопытстве", но все же...

ЦитироватьIndia aims to crack 'methane mystery' with Mars mission[/size]
Last Updated: Tuesday, August 28, 2012, 15:00

 Bangalore: India's proposed mission to Mars in November next year will attempt to crack the "methane mystery", a veteran space scientist has hinted.

 Speaking to PTI here, former Chairman of Indian Space Research Organisation, Prof U R Rao noted that when the country undertook the Chandrayaan-1 lunar mission, "we didn't know we are going to detect water (on the moon)".

 "First time it has happened (detecting water on the moon) in spite of the fact that we were a late entrant (on exploring moon)," said Rao, a globally respected figure in the field of space.

 Rao, Chairman of the selection committee which finalised experiments to be conducted vis-a-vis the Mars orbiter mission, said: "We have selected very good experiments. One of the experiments is essentially to look for methane...Where the methane comes from (what could be producing methane gas detected in the Martian atmosphere)."

 He said there are many open questions vis-a-vis the Red planet. Right now, there is life only on earth. "Venus is so near to earth, yet it is so inhospitable. Mars is so near to the earth, yet it has very, very thin atmosphere, very little of oxygen. Mars has some magnetic materials all over but it does not have a magnetic field, why, There is very little known of Mars," Rao observed.
 

 Rao said Mars has a great amount of relevance because in about "500 years or lesser, we might be able to use Mars as a resource for earth."

 "We are running out of resources in the world," he said. "There are many people who believe Mars can be made hospitable and of course it requires a lot of efforts."

 ISRO aims to do quite a good number of scientific experiments with its Mars mission. "Some experiments have been selected and some are on the waiting list. The weight capability is not high. Total weight of the experiments selected can?t be more than 15 kg," he added.

 According to ISRO officials, the cost of the proposed unmanned Mars orbiter mission is Rs 450 crore. The orbiter is planned to be launched using India's Polar Satellite Launch Vehicle (PSLV-XL) from Satish Dhawan Space Centre, Sriharikota.

ЦитироватьQualms About India's Plan for a 2013 Mars Mission[/size:8837aa7114]
by Pallava Bagla on 21 August 2012, 1:15 PM

NEW DEHLI—Prime Minister Manmohan Singh made it official in his 15 August Independence Day address: India will be launching a $100 million spacecraft to Mars, possibly as soon as November 2013. However, the mission is already being criticized for extravagance and poor planning.

The project, which received cabinet approval a few weeks ago, would place a satellite in an elliptical orbit around the Red Planet and monitor its atmosphere. Among the instruments being considered to ride aboard the craft—known as Mangalyaan or "auspicious vehicle to Mars"—are a multispectral camera, sophisticated spectrometers, and a highly sensitive methane sensor. One aim, according to documents obtained by Science from the national space agency, is to assess "whether Mars has a biosphere or even an environment in which life could have evolved."

Mangalyaan would be "a national waste," says G. Madhavan Nair, the former chair of the Indian Space Research Organisation (ISRO). He oversaw India's first imaging mission to the moon, Chandrayaan-1, launched in 2008, but recently has fallen out with ISRO management. He describes the Mars project as "a half-baked, half-cooked mission being attempted in undue haste with misplaced objectives."

Skeptics also can be found among social scientists such as Jean Drèze, a development economist at the Delhi School of Economics here. "I don't understand the importance of India sending a space mission to Mars when half of its children are undernourished and half of all Indian families have no access to sanitation," Drèze told the Financial Times. He suggested it was "part of the Indian elite's delusional quest for superpower status."

A top government official who reviewed the Mangalyaan project but didn't want to be named rejects the argument that India should give priority to social spending, saying: "I think we have heard these arguments since the 1960s about a poor country not needing or affording a space program. If we can't dare dream big it would leave us as hewers of wood and drawers of water! India is today too big to be just living on the fringes of high technology."

Physicist Krishan Lal, president of the Indian National Science Academy here, says it would have been "better if the larger scientific community were also consulted by ISRO on the scientific merits of the Mars mission," as was done before the initiation of the moon probe. Still, Lal says of the Mars program: "I welcome this development."

Others question the tone of the prime minister's announcement. Why is it called a "huge step," some ask, if six nations have already attempted missions to Mars, and the United States now has two NASA rovers beaming data back from the planet's surface? And why, they ask, is India in a hurry to undertake a mission alone in 2013? The plan contrasts with Chandrayaan-1, which included international partners and took more than a decade to build and launch.

D. Raghunandan, a mechanical engineer and secretary of the independent Delhi Science Forum here, sees the Mars project as "a highly suboptimal mission with limited scientific objectives." He argues that ISRO should have waited until a larger rocket—the Geosynchronous Satellite Launch Vehicle (GSLV)—is available, which he says was "really the original plan." But ISRO defends its decision to use the smaller Polar Satellite Launch Vehicle, saying that GSLV is out of commission due to two back-to-back failures in 2010. According to ISRO, India would miss the earliest opportunity to reach Mars if it waited for the bigger GSLV to be up and running. Mars makes an approach to Earth in 2013; if India missed that launch window it would have to wait until 2016 for the next good opportunity.

Other experts suggest that it is not so much the planetary configuration as Earthbound geopolitical considerations that weigh on India's mind, specifically the rivalry with China. China has been ahead of India in reaching many space goals—including a survey of the moon—but Indian leaders may see the Mars race as a chance for India to take the lead. In November 2011, China's orbiter Yinghuo-1, which was set to ride to Mars on the Russian satellite Phobos-Grunt, ended in disaster when managers lost control of the satellite. This gave India a chance to march ahead.

ISRO's current head, K. Radhakrishnan, told Science in June that "it is high time ISRO got out of making assembly line repeats of the Polar Satellite Launch Vehicle and communication satellites." That is best done by industry, he argued. He said that the nation's "next big challenge" was to go to Mars.

Critics say it is a huge challenge. Nair, for example, says that the highly elliptical orbit planned for Mangalyaan will take it far from the planet most of the time, and in his opinion the "minuscule 25 kg scientific payload" may not be able to contribute much to the understanding Mars. Nair feels money would be better spent improving the big GSLV rocket. It could launch a more robust Mars mission and be used for India's planned missions to study an asteroid, and even for human space flight.

Even The Times of India urged caution in a 9 August editorial, arguing that when the economy is in doldrums, "the Indian space program would do well to grow at its own pace rather than proceed with expensive and imitative projects out of a false sense of national pride." But ISRO doesn't agree; in an official document submitted to the government for the approval of the Mars mission, it says, "India cannot afford to lag behind in its independent exploration of the Red Planet."

А ведь ещё работы в Солнечной системе непочатый край: одних астероидов тысячи и сотни тысяч, причём очень и очень разных разных, и о большинстве известно только из телескопических наблюдений.... про транснептуновые объекты и вспомнить страшно - полно довольно крупных тел (вкл. карликовые планеты), все очень разные, и о всех очень скудная информация.

Емнис, "вулканоиды" размером более 70-100 км внутри орбиты Меркурия не обнаружены - то есть могут быть несколько астероидов на круговых устойчивых орбитах, но размерами в несколько км или несколько десятков км и не более. То есть карликовых планет рядом с Солнцем нет.

ЦитироватьMars mission aimed at scientific development, not space war: ISRO[/size]
PTI

Sriharikota (AP) Sep 9:

ISRO today denied it is locked in a space war with China and said its Mars Mission was aimed at learning more valuable lessons as a scientific community.

"We never raced with anybody. In space, science drives technological development and that will subsequently result in developing an application," ISRO chief Dr K. Radhakrishnan said in reply to a question from a reporter on whether India is locked in a space war with China.

He said the Mars Mission has relevance and one may understand many problems, including methane (there). "The mission, approved recently by the Cabinet, is a challenge and ISRO is geared to face it," he said.

K. Radhakrishnan said the Mars Mission is a time-bound programme which would ensure development of new technology and applications. He mentioned India is one among the top six countries to have a successful space programme.

The satellite would be ready by November 2013 and the conducive period to launch it would be during that time when Mars would come close to Earth, he said. "Challenges include developing new technology, reliable launch vehicle and the objective was to achieve an elliptical orbit of 500 km closest and 80,000 km farthest," he said.

The mission would involve a voyage of 300 days and there would be a series of operations after the vehicle leaves Earth's orbit, the ISRO chief said.

"From the lessons learnt in Chandrayaan (lunar) mission, we need to build on-board automation so that the satellite will manage itself in any eventuality," he said.[/size]

On the mission to Mars next year, Radhakrishnan said that India was not in race with China on this. "We have our own learning from the mission," he told newspersons after the successful launch of PSLV-C21. "It (Mars) is a challenging mission where we will develop new technologies."

The Union Cabinet recently cleared ISRO's mission to Mars.

The project, which comes close on the heels of the Chandrayaan mission to the moon, envisages putting a spacecraft in the red planet's orbit to study its atmosphere, with the help of the PSLV.

The launch is slated for November next year from the Sriharikota range, 80 km north off Chennai. The Space Commission gave its clearance for the mission in December last. The spacecraft will have a scientific payload of 25 kg and is proposed to be placed in an orbit of 500x80,000 km around the planet. This will be a major milestone in the country's space programme, he said.[/size]
