After the Moon and Mars, ISRO eyes Venus for next exploration mission

earth-2
After the successful launch of its Mars orbiter, the Indian Space Research Organisation (ISRO) is now viewing Venus as possibly the next planet it can study and explore.
“Besides the Mars-2 mission, we are looking at Venus and even an asteroid for exploration. A project has to be formulated for this before we chart out a proper roadmap for the explorations.  Venus is our neighbour and has many scientific challenges and aspects that need to be studied. Exploring an asteroid is also challenging task,” Dr Kiran Kumar, Isro chairman, told HT.
In 2014, India created history in space when its Mars orbiter slipped into the Red Planet’s orbit in its maiden attempt.
India became the first Asian country to reach Mars and the first in the world to enter the orbit of the planet in its first attempt.

Regarding the Saarc satellite, Dr Kumar said that it would be launched before December 2016. “The activities related to this project are in progress and we should begin building the satellite soon.”
Moving beyond satellite launches and planetary explorations, Isro is also aggressively working with many government departments on optimising the usage of space tools and data.
A national meet on space is likely to be held in Delhi next month, where ministries and departments of the government will give presentations on how they are using space tools in their workings. From civil aviation to railways, tribal affairs to health, postal to agriculture the number of government departments working with Isro has increased to more than 60 in the past few months.

Biggest commercial mission! ISRO to launch 5 British satellites on July 10


Indian Space Research Organization (ISRO) on Sunday announced that it will be launching five British satellites on July 10, which will be the thirtieth flight of the PSLV (Polar Satellite Launch Vehicle) and the biggest ever commercial mission by the Indian space reasearch centre.

In the heaviest ever commercial mission undertaken by ISRO and its commercial arm Antrix, the country’s workhorse the Polar Satellite Launch Vehicle (PSLV) will put in orbit five foreign satellites from the spaceport of Sriharikota in Andhra Pradesh on July 10.

With the overall lift-off mass of the five satellites amounting to about 1,440 kg, this mission becomes the heaviest commercial mission ever undertaken by Antrix/ISRO, the Indian space agency said.
In its 13th flight, PSLV-C28 will launch three identical DMC3 optical earth observation satellites built by Surrey Satellite Technology Limited (SSTL), United Kingdom (UK).

The three DMC3 satellites, each weighing 447 kg, will be launched into a 647 km Sun-Synchronous Orbit (SSO) using the high-end version of PSLV (PSLV-XL), ISRO said on its website.  PSLV-C28 will be the ninth flight of PSLV in ‘XL’ configuration.

In addition, the rocket will also carry two auxiliary satellites from UK - CBNT-1, a technology demonstrator earth observation micro satellite built by SSTL, and De-OrbitSail, a technology demonstrator nano satellite built by Surrey Space Centre, it said.

Accommodating the three DMC3 satellites each with a height of about 3 metre within the existing payload fairing of PSLV, was a challenge, ISRO said.

To mount these satellites onto the launcher, a circular Launcher adaptor called L-adaptor and a triangular deck called Multiple Satellite Adapter-Version 2 (MSA-V2), were newly designed and realised by ISRO for this specific purpose.

Dwarf planet Ceres reveals pyramid-shaped mystery



OK, this is just too much.
First, NASA's Dawn probe spotted curiously sparkly bright spots on the surface of Ceres, the dwarf planet that lies in the asteroid belt between Mars and Jupiter.
Beats us, the scientists said.
Now, cameras on the tractor-trailer-size spacecraft have captured a baffling structure rising 3 miles above the planet's cratered surface.
Conveniently, the thing looks an awful lot like a pyramid.
    "Intriguing," the NASA scientists said.


    To be fair, the agency offered no suggestion that the towering structure is an offering to some long-lost space emperor or home to our new alien overlords.
    And, to be even more fair, it's probably just a really tall mountain in a solar system filled with wondrous and strange natural phenomena.
    But the Dawn mission has done nothing but stoke imaginations since the discovery of mysterious bright spots on the surface of the dwarf planet in February and the beginning of the probe's orbit in March.
    Folks have claimed to have spotted giant alien motherships hovering over the planet, bat-winged spaceships parked on its surface and even evidence of alien cities.
    But the mystery only deepened with the most recent batch of images showing even more bright spots alongside the largest one, which NASA said looks to stretch some 6 miles.
    Many, of course, insist that the spots look for all the world like brightly lit cities twinkling on the shadowed surface of the distant dwarf planet.
    I knew it! There's gambling going on on Ceres! #aliens pic.twitter.com/QP6PB6JFho

    — Chris Reher (@Chris_Reher) June 13, 2015
    Of course, NASA hasn't traveled down that road. Scientists, they say, still don't know what the spots are. Maybe ice. Maybe salt.
    "But scientists are considering other options, too," NASA said coyly.
    But #itsaliens, right?

    Huge Saltwater Ocean Found on Jupiter Moon Ganymede

    15-033i1

    Artistic Impression of Ganymede (Largest Moon in the Solar System)

    NASA has confirmed that Ganymede, one of the moons orbiting Jupiter, has a saltwater ocean lying below its icy exterior, making it a viable location for life to flourish.

    The scientists studying the planet and its outlier moons through the Hubble Telescope shared the news in a statement Thursday, saying that the ocean may bear more liquid than all the water on Earth combined.

    Ganymede is an anomaly among moons. It is the largest known moon in our solar system, and the only one that generates its own magnetic field. This attribute produces a phenomenon called aurorae—strips of radiant electrified gas that circle Ganymede’s poles. Because Ganymede is situated so close to its mother planet, any changes to Jupiter’s magnetic field directly affect that of its moon. So when Jupiter’s magnetic field shifts due to the planet’s rotation, Ganymede’s aurorae “rock” back and forth in a sort of cosmic mating dance.

    Observing the interplay between the planet and its moon, scientists surmised that an ocean works against Jupiter’s magnetic pull, causing Ganymede to rock less violently than they had anticipated. Once they had observed the planet with the Hubble Telescope, the researchers built computer models that supported speculation that Ganymede has a salty ocean.


    Researchers believe the subterranean ocean is 10 times as deep as Earth’s oceans.


    Since water is necessary to sustain life, it’s possible that these oceans may confirm the long-suspected presence of life on other planets, or on moons such as Titan and Enceladus.


    NASA has speculated since the 1970s that there was water on Ganymede. A 2002 Galileo mission confirmed that the moon had its own magnetic field, but the findings weren’t concrete enough to corroborate suspicion that Ganymede had a vast ocean beneath its outer crust—until now. In a statement, an assistant administrator of NASA’s Science Mission Directorate, John Grunseld, said, “A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth.”

    Russia to create joint orbital station with India, China

    brics-logo1

    Russia is exploring the possibility of a joint manned orbital station with India and China as part of a common strategy to create technological alliances and may take up the matter with the two Asian space giants in July.
    "Moscow could propose to China and India to create a joint manned orbital station at the summit of the BRICS emerging economies in Russia's Ufa in July," a document drafted by the expert council at Russia's military and industrial commission said.
    The experts recommend "working out the possibilities of an international manned project with BRICS (Brazil, Russia, India, China, and South Africa) countries as part of a common strategy of creating technological alliances", Itar Tass reported.
    The proposal comes after months of speculation that the crisis in Ukraine would doom U.S.-Russia space cooperation. For two decades this effort has largely been focused on the International Space Station project (ISS), which is due to end in 2020. NASA has proposed extending it to 2024, but Russia has suggested it might duck out and instead build its own space station — possibly with the participation of China.
    The BRICS project would be roughly analogous to the ISS, a $150 billion project involving 15 nations. Anchored by the United States and Russia, the world's leading spacefaring powers, the ISS allows countries with less advanced spaceflight capabilities to either join onto the station's Russian and American segments or contribute smaller segments.
    A BRICS space station would likely emerge from a similar two-nation partnership, again with Russia in a driver's seat. The Military-Industrial Commission recommended approaching either China or India — both countries that have well-developed and increasingly ambitious space programs. The proposal would then allow other BRICS members to join.
    India has yet to put a man in space without hitching rides on other nations' rockets. Last year, it demonstrated its rising capabilities after launching an unmanned satellite to Mars on a shoestring budget.
    China is perhaps the best partner for such a project. China already launches its own astronauts into space, and is designing its own medium-sized space station. The placement of Russia's new Vostochny Cosmodrome in Russia's Far East also makes close cooperation with China far easier.

    Planets orbiting Kepler 444 suggest there’s ancient life in the Milky Way

    red_star_by_enricoagostoni

    NASA’s exoplanet hunting Kepler space telescope has encountered a few problems as of late, but there’s still a mountain of data for astronomers to dig through from the last four years. Astronomers analyzing Kepler data recently uncovered something unusual — a solar system about 117 light years away in the direction of Lyra called Kepler-444 with at least five Earth-sized planets. That would be unusual enough, but this planetary system is also extraordinarily ancient at roughly 11.2 billion years.
    Astronomers are intrigued by this discovery for several reasons. First, that’s a lot of small rocky planets. Kepler detects alien worlds by the transit method. It watches distant suns for slight dips in brightness that indicate a planet has passed between it and the telescope. These events can be used to calculate the characteristics of the planet, but it works best for larger worlds (super Earths and gas giants). Spotting five planets between the size of Mercury and Venus (basically a little smaller than Earth) is unusual.

      Kepler-444
    Artistic Depiction of Kepler 444 with its Star
     The age of Kepler-444 is also something to note. At 11.2 billion years old, the planets orbiting this star were already older than Earth is now when our sun ignited 4.5 billion years ago. The universe itself is only 13.8 billion or so years old, making Kepler-444 one of the oldest stars in the Milky Way. It would have been from the first generation of stars that dotted the sky. Kepler-444 is still very sun-like because it’s 25% smaller and cooler. That means it burns through its nuclear fuel more slowly.
    Finding small rocky planets that are billions of years older than Earth suggests that advanced life may have existed in the universe for a very long time. Life on Earth might be very new by comparison. Just think, planets similar to Earth were forming more than 7 billion years before Earth formed, and some of them could have supported life. If other first-generation stars like Kepler-444 have planets, uncountable civilizations could have come into being eons before the first single-cell life appeared on Earth.
    The planets orbiting Kepler-444 themselves are not able to support life as we know it. All five planets are packed very close to the parent star with orbits closer than that of Mercury in our solar system. With solar years less than 10 Earth days, they definitely stood out in the Kepler data. The surfaces of these worlds have been baked by the intense heat, reducing any organic material to cinders.
    Kepler-444 isn’t a bastion of alien life, but it improves our understanding of planetary formation and points us in a new direction. Astronomers are anxious to find other ancient stars with rocky planets in hopes they might prove more hospitable to life. What if there was still something alive on one of these ancient worlds? That might sound like science fiction right now, but maybe it won’t always be — there’s still a lot of data from Kepler, and future telescopes will improve our ability to spy distant exoplanets.

    SpaceX, Boeing on Track to Take Astronauts to Space Station by 2017

    6e336ff4a48cc206652aa9e6551a8e5d_large

    The agency will use the partnership to end dependency on Russia

    SpaceX has completed the first certification milestone in its CCP commitment, and will spend much of 2015 testing abort solutions for its formerly cargo-only Dragon capsule. (Abort procedures are more critical in crewed missions.) A launchpad abort will be tested in the next two months at Cape Canaveral, and an in-flight abort test will follow "later this year," according to SpaceX President and COO Gwynne Shotwell. Uncrewed missions to the ISS with the new capsule will start in 2016, and the company is still working out the makeup of its first test flight crew.

    spacex-boeing
    "I DON'T EVER WANT TO HAVE TO WRITE ANOTHER CHECK TO ROSCOSMOS."

    The company is also working on outfitting its Dragon capsule with propulsive landing, Shotwell said, which could improve reusability by dispensing with the need to splash down in water. Instead, the capsule would land right at Johnson Space Center, using rockets on the bottom to help control the descent. That's not the only new technology the company is working on. It hopes to outfit its Falcon 9 rockets with wings and retrorockets so they can land on autonomous barges in the ocean.

    Boeing has completed the first two certification milestones for its CST-100 spacecraft. NASA has signed off on parts of its commercial crew operation, including designs for the control center, training systems, flight simulators, and software. Boeing has also started building its crew access tower on the Atlas V launchpad, and that construction will continue in between uncrewed Atlas V launches.

    The CST-100 will undergo a critical design review in March, and if approved, will let the company launch "full-bore" into manufacturing, according to VP and General Manager of Boeing Space Exploration John Elbon. Boeing's spacecraft can fit up to seven crew members, and is also being designed with reusability in mind. According to Elbon, the plan is for the capsule to be recovered, refurbished, and reused up to 10 times.

    When asked how this all fits in with the 2016 budget, Bolden said he's "very optimistic." "Congress has, I think, kind of started to understand the critical importance of commercial crew and cargo. They've seen, as a result of the performance of our providers, that this is not a hoax. It's not a myth. It's not a dream," he said. "It's something that really is happening."

    Scientists Discover Exoplanet With Rings Far More Impressive Than Our Saturn

    J1407b

    Children and adults alike marvel at the rings around Saturn. In a model of our solar system, Saturn—and its rings—is typically the one that gets the most attention.

    But while it is easy to be fascinated by Saturn, astronomers have recently found an exoplanet with an even grander expanse of wings that is sure to wow a new generation of stargazers.

    “The star is much too far away to observe the rings directly, but we could make a detailed mode based on the rapid brightness variations in the star light passing through the ring system. If we could replace Saturn’s rings with the rings around J1407b, they would be easily visible at night and be many times larger than the full moon,” explains lead researcher Matthew Kenworthy. “The details that we see in the light curve are incredible. The eclipse lasted for several weeks, but you see rapid changes on time scales of tens of minutes as a result of fine structures in the rings.”

    Study co-author Eric Mamaek, who first found the rings of the planet, comments, “The planetary science community has theorized for decades that planets like Jupiter and Saturn would have had, at an early stage, disks around them that then led to the formation of satellites. However, until we discovered this object in 2012, no-one had seen such a ring system. This is the first snapshot of satellite formation on million-kilometer scales around a substellar object.”

    The University of Rochester professor of physics and astronomy goes on to say, “This planet is much larger than Jupiter or Saturn, and its ring system is roughly 200 times larger than Saturn’s rings are today. You could think of it as a kind of super Saturn.”

    NASA unveils 100-millionth picture of the sun

    10948933_770503933005593_281558100_n

    An instrument onboard the Solar Dynamics Observatory captured NASA's 100-millionth image of the sun. Four telescopes work parallel to capture eight images of the sun and cycle through 10 different wavelengths every 12 seconds.

    A National Aeronautics and Space Administration instrument aboard a sun-viewing spacecraft has captured its 100-millionth image of the sun.

    The instrument, on the Solar Dynamics Observatory, is the Atmospheric Imaging Assembly and uses four telescopes. The photo was taken Jan.19, according to NASA.

    https://www.youtube.com/watch?v=7VVxdN79QZY

    In the nearly five years since its start in 2010, Solar Dynamics Observatory has captured images of the sun "to help scientists better understand how the roiling corona gets to temperatures some 1,000 times hotter than the sun's surface, what causes giant eruptions such as solar flares, and why the sun's magnetic fields are constantly on the move," NASA says.

    Researchers: Solar system may have Planet X , Planet Y

    planet-surface-18356-1920x1080

    The presence of two additional planets might explain the unexpected orbital features of some trans-Neptunian objects.

    Scientists have postulated the existence of possibly two undiscovered planets beyond the orbit of Neptune to explain discrepancies in the orbits of extreme trans-Neptunian objects (ETNO). The objects have orbits that take them beyond the orbit of the planet Neptune.

    Theory predicts that they be randomly distributed and that their orbits must have a semi-major axis with a value around 150 AU; an orbital inclination of nearly zero degrees; and an angle of perihelion, the point in the object’s orbit at which it is closest to the Sun, of zero to 180 degrees.

    However, a dozen ETNO do not fit these orbital criteria. These objects have semi-major axis values of 150 to 525 AU, orbital inclinations of around 20 degrees, and angles of perihelion far from 180 degrees.

    According to a statement, a new study by astrophysicists at the Complutense University of Madrid (UCM) and University of Cambridge have calculated that these orbital discrepancies could be explained by the existence of at least two additional planets beyond the orbits of Neptune and dwarf planet Pluto. Their study suggests that the gravitational pulls of those two planets must be disturbing the orbits of some smaller ETNO.

    However, there are two difficulties with the hypothesis. One is that current models of the formation of our solar system do not allow for additional planets beyond Neptune. Secondly, the team’s sample size is very small, only 13 objects. However, additional results are in the pipeline, which will expand the sample.

    “This excess of objects with unexpected orbital parameters makes us believe that some invisible forces are altering the distribution of the orbital elements of the ETNO and we consider that the most probable explanation is that other unknown planets exist beyond Neptune and Pluto,” said Carlos de la Fuente Marcos of UCM and lead author on the study.

    The new findings have been published in two papers published in the journal Monthly Notices of the Royal Astronomical Society Letters.

    Philae sleeps, but Rosetta's not done yet

    Follow us on Google+ , Twitter and Facebook

    Its battery dead, the European lander is lost in a crater somewhere on a huge comet. But the orbiter that brought it there still has plenty of science left to do.

    Rosetta

    As of Saturday morning, the Philae lander is in a digital coma somewhere on the surface of comet 67P/Churyumov-Gerasimenko. But even if the history-making little robot never wakes again, the Rosetta mission and the orbiter of the same name still have a long journey ahead of them.

    The plan was for Philae to land at a targeted site on the comet, firing harpoons into the surface of the icy rock to keep itself locked in place for a long trip around the sun. The strong grip was particularly important since a comet this size has only a tiny fraction of the gravity of a place like Earth, leaving little Philae at risk of floating off into space.

    But when showtime came, there were problems with Philae's downward thrusters and with firing the harpoons. The European Space Agency reports that the lander bounced off the surface of the comet twice and eventually landed somewhere else without much access to the sunlight its solar panels need to keep it functioning.

    Friday evening, Philae used its remaining energy to upload all its data before going into hibernation mode. There was a time slot early this morning during which, the ESA had reported, communication with the lander was possible, but that time has now come and gone.

    Still, Rosetta remains.

    Even if Philae stays lost in a comet crater for the next year, the orbiter that traveled almost half a billion miles to get to this point will continue to orbit the comet and its lost lander.

    Right now, Rosetta has been pulling out to a 30 kilometer orbit of the comet. It will come closer again early next month to get more details on the comet -- some of its flybys will be as close as 8 kilometers to the comet. There's a whole lot of potential science and data about comets, planets and our solar system packed in that process, building up to the trio's closest encounter with the sun, next August.

    Before that point there may also be better opportunities to rouse Philae.

    3D-printed engine parts future of space launches: NASA

    Follow us on Google+ , Twitter and Facebook

    17104-nasa-logo

    A team of NASA researchers has found that 3D manufactured copper parts could withstand the heat and pressure required of combustion engines used in space launches.

    The US space agency and California-based rocket and missile propulsion manufacturer Aerojet Rocketdyne (AR) conducted 19 hot-fire tests on four injector and thrust chamber assembly configurations at NASA's Glenn Research Centre.

    "The successful hot fire test of engine components provides confidence in the additive manufacturing process and paves the way for full-scale development," said Tyler Hickman, lead engineer for the test at Glenn.

    3D printing approach is changing the speed, cost and flexibility of designing and building future machines for space and earth applications.

    The work is a major milestone in the development and certification of different materials used in the manufacturing process.

    Copper alloys offer unique challenges to the additive manufacturing processes.

    "Additively manufactured metal propulsion components are truly a paradigm shift for the aerospace industry," added Paul Senick, Glenn project manager.

    This will improve efficiency and bring down the cost of space launches and other earth applications, he concluded.

    A Universe of Blue Dots? --"Water Common During the Formation of All Planetary Systems"

    Follow us on Google+ , Twitter and Facebook

    pic-hyper-terra

    The new SciFi blockbuster, Interstellar, shows astonauts from post apocalyptic earth, destroyed by what appears to be a modern dust-bowl, catapulted into the unknown of outer space in the hopes of finding a new home for the human race, only to discover an extraterrestrial tidal wave on a distant exo planet. How realistic is the premise of an alien water planet? New findings suggest it's based on solid science.
    "This is an important step forward in our quest to find out if life exists on other planets," said Tim Harries, from the University of Exeter's Physics and Astronomy department, who was part of the research team. "We know that water is vital for the evolution of life on Earth, but it was possible that the Earth's water originated in the specific conditions of the early solar system, and that those circumstances might occur infrequently elsewhere. By identifying the ancient heritage of Earth's water, we can see that the way in which our solar system was formed will not be unique, and that exoplanets will form in environments with abundant water. Consequently, it raises the possibility that some exoplanets could house the right conditions, and water resources, for life to evolve."
    The implication of these findings is that some of the solar system's water must have been inherited from the Sun's birth environment, and thus predate the Sun itself. If our solar system's formation was typical, this implies that water is a common ingredient during the formation of all planetary systems.

    To date, the Kepler satellite has detected nearly 1,000 confirmed extrasolar planets. The widespread availability of water during the planet-formation process puts a promising outlook on the prevalence of life throughout the galaxy.

    A pioneering new study has shown that water found on Earth predates the formation of the Sun – raising hopes that life could exist on exoplanets, the planets orbiting other stars in our galaxy. The ground-breaking research set out to discover the origin of the water that was deposited on the Earth as it formed.

    It found that a significant fraction of water found on Earth, and across our solar system, predates the formation of the Sun. By showing that water is 'inherited' from the environment when a star is born, the international team of scientists believe other exoplanetary systems also had access to an abundance of water during their own formation.

    As water is a key component for the development of life on Earth, the study has important implications for the potential for life elsewhere in the galaxy.

    Scientists have previously been able to understand the conditions present when stars are formed by looking at the composition of comets and asteroids, which show which gases, dust and, most importantly, ices were circling the star at its birth.

    The team of international scientists were able to use 'heavy water' ices – those with an excess of water made with the element deuterium rather than hydrogen – to determine whether the water ices formed before, or during, the solar system's formation.

    ISRO plans second mission to Mars in 2018

    Follow us on Google+ , Twitter and Facebook


    earth-space-hd-wallpaper-1920x1080-9805

    The Indian Space Research Organisation (ISRO) is planning to launch second mission to Mars with a lander and rover to carry out more experiments on the red planet.

    The proposed plans come after the Indian space agency has successfully placed its unmanned Mars Orbiter Mission spacecraft to the Martian orbit in September.

    ISRO satellite centre director Shiva Kumar was quoted by IANS as saying: "We plan to launch a second mission to Mars in 2018, probably with a lander and rover, to conduct more experiments for which we have to develop new technologies.

    "We will be able to take the Mars-2 mission after launching the second mission to the moon (Chandrayaan-2) in 2016 with our own lander and rover, which will help us develop a separate lander and rover for the red planet."

    The agency is looking to launch the programme in 2018 as the missions to Mars can be launched at two year intervals.

    ISRO intends to have fully operational heavy rockets ready by then to carry communication satellites weighing around 3t into the geo-stationary orbits around the earth.

    In line with this plans, the agency has developed the geo-synchronous satellite launch vehicle (GSLV Mark I-III) to launch heavier communication satellites.

    GSLV Mark-III is scheduled to take its first partial test flight in early December.

    ISRO chairman Radhakrishnan was quoted by The Hindu as saying that the test flight will lead to a 'future workhorse vehicle that will stay with us for many years'.

    Tests will be conducted on unmanned crew module of the three-stage launch vehicle, to evaluate heating during its re-entry and its behaviour in the crucial space phase.

    Isro to Test Crew Module in December for India's First Human Space Flight

    index

    India will launch an unmanned crew module in December onboard a heavy rocket to test its re-entry into the atmosphere for the country's maiden human space flight, the space agency chief said Thursday.
    "We will send an unmanned crew module on the experimental GSLV-Mark III rocket in December and test its re-entry into the earth's atmosphere for a human space flight plan in future," Indian Space Research Organisation (Isro) Chairman K. Radhakrishnan told reporters in Bangalore on the margins of an engineers conclave.

    Weighing 3.6 tonnes, the crew module will be put into orbit 100-120km up in a satellite and brought back to Earth for checking its re-entry characteristics when carrying two Indian astronauts in the proposed human space flight.

    "Though the actual human space flight will be in an orbit around earth at a height of 270km for a week, the experimental flight with the crew module in a spacecraft will go up to 100-120km above earth to test its heat shield survive very high temperatures (about 1,500 degrees Celsius) during the re-entry into the atmosphere," Radhakrishnan noted.

    The crew module will have a parachute that will open up after re-entry into the atmosphere and fall into sea for retrieval.

    "The parachute will open up for soft landing of the spacecraft carrying the crew module in the Bay of Bengal, about 450 km away from Andamans (islands), and will be retrieved by a boat," Radhakrishnan said.

    The previous UPA government had sanctioned Rs. 145 crores to Isro for developing a crew module that will fly two Indian astronauts into space, space suits, life support systems and related technologies for the human space flight programme.

    The heavy rocket (GSLV) will, however, have a passive cryogenic stage - liquid nitrogen at super cooled temperature and gaseous nitrogen instead of liquid hydrogen and liquid oxygen.

    The space agency is integrating the rocket with the crew module at its Sriharikota spaceport in Andhra Pradesh, about 90 km northeast of Chennai.

    China's Main Competitor in Space Exploration is India, Not Russia

    China-India-Flag

    China's principal competitor in space exploration is India, not Russia, researcher at the Russian Centre for Analysis of Strategies and Technologies Vasily Kashin told RIA Novosti on Friday.

    "China and India are two new space powers. They have vast resources and consider their space programs from the national prestige perspective ," the expert said.

    He added that China and India are following Russian and US footsteps in space exploration.

    "China's more developed space-rocket industry and immense resources have let it take the lead in the two countries' space race," Kashin argued.

    Despite being behind China in space exploration, India has a significant advantage, according to the researcher.

    "China is still under rigid restrictions on any form of cooperation with the United States, including on the purchase of components...The Chinese are forced to do many things on their own and they sometimes cannot produce components of a required level. The Indians have less resources, but they are in good relations with everyone. India can cooperate with both Russia and the West, adopting their best technologies," Kashin concluded.

    Earlier on Friday, China launched an experimental spacecraft to the moon orbit, which is to return to Earth in eight days. The spacecraft is to test out re-entry into the Earth's atmosphere for the planned 2017 Chang'e-5 lunar mission.

    The Indian Space Research Organisation (ISRO) has announced that the country's most ambitious space project - Mars Orbiter Mission (MOM) - is scheduled for launch on 28 October.

    Last week, ISRO scientists gave a detailed presentation about the Mars mission before a national committee of experts. After reviewing the status of MOM, the panel of experts, including former ISRO chairman UR Rao, space expert Roddam Narasimha and professors from Indian Institute of Science, gave approval to launch the mission on 28 October.

    Earlier, ISRO officials allotted a launch window of 21 October to 14 November, but now the launch date has been fixed for 28 October though the final date of the launch window remains the same (19 November).
