6. There are few things which need correction in your article. First India is not a Federal structure, so the approval is not given by Federal government. Correct term would be Central government. I am really surprised how quickly the Indian origin folks forget their roots (or wont remember what government structure is followed in India) and rather cozy up to US way of talking.

Second and most important, “Certain Russian commitments didn’t materialize”???? Not surprised that you have selective amnesia about how US blocked the tech transfer and purchase of cryogenic engines from Russia on the pretext that it will violate MTCR (Missile Technology Control Regime) treaty. Can anybody tell which missile in the world uses Cryogenic Engines? And to ask about MTCR treaty’s application it self – Recent news about Saudi Arabia purchasing DF21 missile from China – why didn’t US block it since its clear violation of MTCR???

GSLV has 2 versions of the rocket, your statement that payload will double for GSLV holds good for first version. The second or also called as Mark III can actually launch 4.5ton category satellite’s on par with rest of the world. Read up more about the topic before you jump at the keyboard to write such myopic article.

7. and hey……ESA’s Space Express is launched on a Russian Soyuz rocket, which you conveniently ignored before proceeding with your Macaulayite preaching.

So ISRO is the first Space agency that successfully launched and orbited a Mars mission in the fist attempt…now beat that.

A renewed U.S.-India partnership for the 21st century

By Narendra Modi and Barack Obama September 30 at 8:00 AM

Narendra Modi is prime minister of India. Barack Obama is president of the United States.

As nations committed to democracy, liberty, diversity and enterprise, India and the United States are bound by common values and mutual interests. We have each shaped the positive trajectory of human history, and through our joint efforts, our natural and unique partnership can help shape international security and peace for years to come.

Ties between the United States and India are rooted in the shared desire of our citizens for justice and equality. When Swami Vivekananda presented Hinduism as a world religion, he did so at the 1893 World’s Parliament of Religions in Chicago. When Martin Luther King Jr. sought to end discrimination and prejudice against African Americans, he was inspired by Mahatma Gandhi’s nonviolent teachings. Gandhiji himself drew upon the writings of Henry David Thoreau.

As nations, we’ve partnered over the decades to deliver progress to our people. The people of India remember the strong foundations of our cooperation. The food production increases of the Green Revolution and the Indian Institutes of Technology are among the many products of our collaboration.

Today our partnership is robust, reliable and enduring, and it is expanding. Our relationship involves more bilateral collaboration than ever before — not just at the federal level but also at the state and local levels, between our two militaries, private sectors and civil society. Indeed, so much has happened that, in 2000, then-Prime Minister Atal Bihari Vajpayee could declare that we are natural allies.

After many years of growing cooperation since, on any given day, our students work together on research projects, our scientists develop cutting-edge technology and senior officials consult closely on global issues. Our militaries conduct joint exercises in air, on land and at sea, and our space programs engage in unprecedented areas of cooperation, leading us from Earth to Mars. And in this partnership, the Indian American community has been a vibrant, living bridge between us. Its success has been the truest reflection of the vitality of our people, the value of America’s open society and the strength of what we can do when we join together.

Still, the true potential of our relationship has yet to be fully realized. The advent of a new government in India is a natural opportunity to broaden and deepen our relationship. With a reinvigorated level of ambition and greater confidence, we can go beyond modest and conventional goals. It is time to set a new agenda, one that realizes concrete benefits for our citizens.

This will be an agenda that enables us to find mutually rewarding ways to expand our collaboration in trade, investment and technology that harmonize with India’s ambitious development agenda, while sustaining the United States as the global engine of growth. When we meet today in Washington, we will discuss ways in which we can boost manufacturing and expand affordable renewable energy, while sustainably securing the future of our common environment.

We will discuss ways in which our businesses, scientists and governments can partner as India works to improve the quality, reliability and availability of basic services, especially for the poorest of citizens. In this, the United States stands ready to assist. An immediate area of concrete support is the “Clean India” campaign, where we will leverage private and civil society innovation, expertise and technology to improve sanitation and hygiene throughout India.

While our shared efforts will benefit our own people, our partnership aspires to be larger than merely the sum of its parts. As nations, as people, we aspire to a better future for all; one in which our strategic partnership also produces benefits for the world at large. While India benefits from the growth generated by U.S. investment and technical partnerships, the United States benefits from a stronger, more prosperous India. In turn, the region and the world benefit from the greater stability and security that our friendship creates. We remain committed to the larger effort to integrate South Asia and connect it with markets and people in Central and Southeast Asia.

As global partners, we are committed to enhancing our homeland security by sharing intelligence, through counterterrorism and law-enforcement cooperation, while we jointly work to maintain freedom of navigation and lawful commerce across the seas. Our health collaboration will help us tackle the toughest of challenges, whether combating the spread of Ebola, researching cancer cures or conquering diseases such as tuberculosis, malaria and dengue. And we intend to expand our recent tradition of working together to empower women, build capacity and improve food security in Afghanistan and Africa.

The exploration of space will continue to fire our imaginations and challenge us to raise our ambitions. That we both have satellites orbiting Mars tells its own story. The promise of a better tomorrow is not solely for Indians and Americans: It also beckons us to move forward together for a better world. This is the central premise of our defining partnership for the 21st century. Forward together we go — chalein saath saath (चलें साथ साथ ).

What sorcery is this? Get your 3D glasses to look at Mars the way I do!

In fact, Mars Express made ESA the first nation/ region to succeed at its first attempt. Both Japan (Nozomi) and China (Yinghuo 1) have attempted
Mars probes which failed. So this is a major first for India, in Asia’s “mini space race”.

Mod hat off. Let's please celebrate achievements here on their own merits instead of making essentially futile comparisons of the "first", "better", etc. variety, which never seem to accomplish anything but raising tensions.

Holy. Ares!

THAT is a full-disk image of Mars taken by India’s Mars Orbiter Mission, or MOM. It was just released this morning and shows nearly an entire hemisphere of the planet.

It’s gorgeous. There’s so much to see! North is to the upper left (roughly the 11:00 position), and the pole looks like it’s covered in a cloudy haze [Update (Sep. 29, 2014 at 17:40 UTC): Ah, according to my friend and fellow science writer Carolyn Collins Petersen, that's a dust storm brewing there.]. The huge, lighter-colored region just to the right and above center is called Arabia Terra, a 4,500-kilometer stretch of uplands that is one of the oldest terrains on Mars. It’s hard to tell from this wide-angle shot, but it’s heavily eroded and covered with craters.

Just below it is a long dark feature called Terra Meridiani (“Meridian Land”; though you could fancifully call it “Middle Earth”). The rover Opportunity is there, still roaming around and poking at the rocks there. This whole area shows evidence that is was once under water.
Nestled in the northern part of Terra Meridiani is the crater Schiaparelli, which is more than 460 km across! That’s huge, far larger than the crater left by the dinosaur-killer impact here on Earth. Straight up from it in Arabia Terra you can also see the crater Cassini (also more than 400 km wide), and to the right, just inside the dark region called Syrtis Major, is the crater Huygens, which is about the same size as Schiaparelli. The astronomers Cassini and Huygens studied Saturn, which is why the Cassini probe is named what it is, and the lander probe it sent to the moon Titan is named Huygens. Those astronomers really get around.

I could go on and on; you can see Hellas Basin as a smooth, butterscotch-colored area to the lower right just on the edge, and the ices of the south pole at the bottom. There are craters galore, and all sorts of wind-eroded areas that so many scientists will happily spend the rest of their lives studying.

But for me, right now, what makes me sigh in awe is the overall perspective of this picture. We’re seeing the entire face of the planet here, a perspective we don’t always get from our probes, sent to study Mars in detail. And the added touch of it not being fully lit—you can see the day-night line, called the terminator, cutting across the planet to the upper left—really drives home that what we’re seeing here really is an entire world, a huge expanse of territory just calling out for us to explore and understand.

There’s a lot of solar system out there to look at, and it fills me with joy to know we’re doing just that.

Rocket fuel, not so much. Of course there is no absolute requirement for O2. CO, HCN, hell Fe+3 can be used with methane to provide an reaction with favourable enthpy.

Venus has some Methane too. What I gather from Wiki is that it may be not as much as on Mars or Titan. Is it too hot for life to survive? Ther emust be an optimum reaction rate.

...High Technology, Space and Health Cooperation

Fundamental science and high technology cooperation has been a critical pillar of the strategic partnership, the two leaders confirmed, and they looked forward to renewing the Science and Technology Agreement in order to expand joint activities in innovative technology. The Prime Minister welcomed the United States as a partner country, for the first time, at India’s annual Technology Summit in November 2014. In addition, they committed to convene the ninth High Technology Cooperation Group (HTCG). They plan to launch new partnerships to source and scale innovation for the benefit of citizens in both countries and to harness innovation to solve global development challenges.

The President welcomed India’s contribution and cooperation on high-energy physics and accelerator research and development with the U.S. Department of Energy. The President thanked the Prime Minister for his offer to have U.S. institutions partner with a new Indian Institute of Technology.

The leaders committed to partner on the Digital India initiative, with the goal of enhancing digital infrastructure, deploying e-governance and e-services, promoting industry collaboration, and digitally empowering India’s citizens. The President welcomed India's proposal to establish the Global Initiative of Academic Networks (GIAN, or Knowledge) under which India would invite and host up to 1,000 American academics each year to teach in centrally-recognized Indian Universities, at their convenience.

The two leaders exchanged congratulations on the successful entry into orbit of their respective Mars missions, which occurred two days apart. They welcomed the establishment and planned first meeting of the NASA-ISRO Mars Joint Working Group under the U.S.-India Civil Space Joint Working Group. The leaders also look forward to the successful conclusion of a new agreement to support the NASA-ISRO Synthetic Aperture Radar (NISAR) mission, to be launched in 2021.

RELEASE 14-266
U.S., India to Collaborate on Mars Exploration, Earth-Observing Mission

In a meeting Tuesday in Toronto, NASA Administrator Charles Bolden and K. Radhakrishnan, chairman of the Indian Space Research Organisation (ISRO), signed two documents to launch a NASA-ISRO satellite mission to observe Earth and establish a pathway for future joint missions to explore Mars.While attending the International Astronautical Congress, the two space agency leaders met to discuss and sign a charter that establishes a NASA-ISRO Mars Working Group to investigate enhanced cooperation between the two countries in Mars exploration. They also signed an international agreement that defines how the two agencies will work together on the NASA-ISRO Synthetic Aperture Radar (NISAR) mission, targeted to launch in 2020.

“The signing of these two documents reflects the strong commitment NASA and ISRO have to advancing science and improving life on Earth,” said NASA Administrator Charles Bolden. “This partnership will yield tangible benefits to both our countries and the world.”

The joint Mars Working Group will seek to identify and implement scientific, programmatic and technological goals that NASA and ISRO have in common regarding Mars exploration. The group will meet once a year to plan cooperative activities, including potential NASA-ISRO cooperation on future missions to Mars.

Both agencies have newly arrived spacecraft in Mars orbit. NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft arrived at Mars Sept. 21. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars. ISRO’s Mars Orbiter Mission (MOM), India’s first spacecraft launched to Mars, arrived Sept. 23 to study the Martian surface and atmosphere and demonstrate technologies needed for interplanetary missions.

One of the working group’s objectives will be to explore potential coordinated observations and science analysis between MAVEN and MOM, as well as other current and future Mars missions.

“NASA and Indian scientists have a long history of collaboration in space science,” said John Grunsfeld, NASA associate administrator for science. “These new agreements between NASA and ISRO in Earth science and Mars exploration will significantly strengthen our ties and the science that we will be able to produce as a result.”The joint NISAR Earth-observing mission will make global measurements of the causes and consequences of land surface changes. Potential areas of research include ecosystem disturbances, ice sheet collapse and natural hazards. The NISAR mission is optimized to measure subtle changes of the Earth’s surface associated with motions of the crust and ice surfaces. NISAR will improve our understanding of key impacts of climate change and advance our knowledge of natural hazards.

NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band) to measure changes in our planet’s surface less than a centimeter across. This allows the mission to observe a wide range of changes, from the flow rates of glaciers and ice sheets to the dynamics of earthquakes and volcanoes.

Under the terms of the new agreement, NASA will provide the mission’s L-band synthetic aperture radar (SAR), a high-rate communication subsystem for science data, GPS receivers, a solid state recorder, and a payload data subsystem. ISRO will provide the spacecraft bus, an S-band SAR, and the launch vehicle and associated launch services.

NASA had been studying concepts for a SAR mission in response to the National Academy of Science’s decadal survey of the agency’s Earth science program in 2007. The agency developed a partnership with ISRO that led to this joint mission. The partnership with India has been key to enabling many of the mission’s science objectives.

NASA’s contribution to NISAR is being managed and implemented by the agency's Jet Propulsion Laboratory (JPL) in Pasadena, California.

NASA and ISRO have been cooperating under the terms of a framework agreement signed in 2008. This cooperation includes a variety of activities in space sciences such as two NASA payloads -- the Mini-Synthetic Aperture Radar (Mini-SAR) and the Moon Mineralogy Mapper -- on ISRO’s Chandrayaan-1 mission to the moon in 2008. During the operational phase of this mission, the Mini-SAR instrument detected ice deposits near the moon’s northern pole.

prasannasimha: Unfortunately, when I was in high school (and studied in Telugu medium till intermediate and that too one school per year and in one year two schools), all books (and majority of the teachers) were uninspiring, biology, though continued till 10th class, was almost done with by 7th class for composite math students. My interest is mostly in Bioinformatics, and computational biology and biological computation. But then I think the last one is not really a viable alternative to General Purpose Computers but certainly has merit as an embedded computing devices into into micro/nano-bio-electro-mechanical systems compute some very specific and simple albeit important functions.

Probably we should start a thread in Science and Tech forum for inter-disciplinary science research generally in the world and specifically in India with no politics/policy/religion of any kind. I might do it in a few days with strict guidelines and immediate reporting to Mods of any infringement of the guidelines happens.
