  2. After seeing this video I remember a dialogue from welcome film by Anil Kapoor "tu goliya barta re jayga aur yaha koi mera game baja dega" wase hi ISRO goliya barta reh Gaya aur NASA ne uski game baja di..😂😂

  3. India ko ab free of cost karne ke koi jarurat nahi h nasa se toh billons of dollar lena chaye tha agar free of cost karna h toh aaise country k karo jo hamare sabse aache dost h na ke selfish US ab nasa yeh thode bolega ke india ka tha contribution

  4. ये कुछ इस तरह हुआ था –
    2008 में इसरो ने चंद्रयान-1 को चन्द्रमा पर भेजा । चंद्रयान-1 में कई pay-load थे जिनमें इसरो का MIP और नासा का M3 भी था । इसरो ने अपने MIP को चन्द्रमा पर पानी की खोज करने लिए बनाया था । चंद्रयान-1 से MIP को चन्द्रमा के दक्षिणी ध्रुव की ओर छोड़ा गया । 6100 किलोमीटर प्रति घंटे की गति से MIP चन्द्रमा की सतह से टकराया जिससे वहाँ एक गहरा गड्ढा हो गया और चन्द्रमा की बहुत सारी भूमिगत मिट्टी ऊपर फूट पड़ी । जैसे ही ये मिट्टी इतनी ऊँची उछली कि वो सूर्य के प्रकाश की जद में आ सके और सूर्य की किरणों को परावर्तित कर सके, ठीक उसी समय चंद्रयान-1 में लगे नासा के M3 उपकरण ने उन परावर्तित किरणों को कैद कर लिया जिनका अध्ययन करने पर उनमें पानी की उत्सर्जन रेखाएँ मिलीं । इससे ये सिद्ध हो गया कि उस मिट्टी में पानी मौजूद था । इसरो का कहना है कि उसके MIP ने भी चन्द्रमा से टकराने से पहले पानी की मौजूदगी का पता लगा लिया था और उन सिग्नलों को चंद्रयान-1 तक भेज भी दिया था पर पर्याप्त सबूत ना होने के कारण इसरो ने इस मामले में कोई research प्रकाशित नहीं की ।
    ध्यातव्य रहे कि नासा ने पिछले एक दशक से चन्द्रमा पर कोई मिशन नहीं भेजा था पर भारत के चंद्रयान-1 से श्रेय छीनने के लिए उसने अगले ही वर्ष 2009 में LRO और LCROSS को चन्द्रमा पर भेज दिया । इनमें LCROSS को चन्द्रमा के दक्षिणी ध्रुव पर गिराया गया और LRO द्वारा उस विस्फोट का विश्लेषण कर वहाँ पर पानी की मौजूदगी को पक्का कर लिया गया । LRO पर लगे LEND न्यूट्रॉन डिटेक्टर से न्यूट्रॉन किरणों को चन्द्रमा के ध्रुवों पर छोड़ा गया । उन न्यूट्रॉन किरणों के चन्द्रमा पर मौजूद पानी से अभिक्रिया होने को रिकॉर्ड किया गया । ऐसा कई वर्षों तक किया गया और चन्द्रमा के ध्रुवों का एक water-ice profile बनाया गया जिसे आप वीडियो में देख सकते हैं । इसी के साथ ही नासा को ये श्रेय मिल गया कि उसने ही सबसे पहले चन्द्रमा पर पानी की सटीक मौजूदगी के बारे में बताया है । इसरो के जिस प्रोजेक्ट के परिणामों से प्रेरित होकर नासा ने चन्द्रमा पर मिशन भेजा था, उस चंद्रयान-1 को भुला दिया गया । इंटरनेट पर उपलब्ध अमरीकी वीडियोज़ पर चंद्रयान-1 का ज़िक्र भी नहीं मिलता । इसरो ने भी नासा के M3 को मुफ़्त में ले जाकर बड़ी भूल की ।

  5. Cnn news: NASA DISCOVERS WATER ON MOON.
    REPORT:NASA has reported to find water on moon on polar caps. "This was done by only NASA without any involvement of any other space research agency". NASA is reputed space agency who never uses others data.

  6. भारतीय अपना सदियों पुराना खोजा जा चूका ज्ञान फिर से खोज निकालेंगे । ये तो शुरुवात है । जय हिन्द

  7. mission kis ka tha ye baat aap janete hai ……… hum jante hai…… america janta hai…duniya janti hai……..or yakin maaniye ISRO ka loha duniya manti hai………PTA NAHI HAMARE KABIL SCIENTIEST KAB VIDESHO KI TARAF NA BHAAG KE APNE DESH KO AAGE LE JANE KE BAARE ME SOCHNA SHURU KARENGE………SUNA HAI NASA MAIN BAHUT SAARE SCIENTIST INDIAN HAI…………

  8. Nasa ko is baat ko to accept krna chahiye ki isse pahle ke jo mission the unke satellite moon ke polar ke Crater or dark spots ke utne achhi tarah se orbit me nhi the bharat ke chandrayan ne jo image bheji thi.

  9. ISRO is great. Free of cost service dena ek saraahniya kaam hai. NASA ke hi instrument ne paani ki khoj ki hai, isliye shreya NASA ko hi jayega. Lekin jo khoj hui hai ussey aagey chalkar insanon ka hi bhala hoga. Shreya milna ya na milna bahut jyada mayney nahi rakhta.

  10. Why are scientists sure of water on the Moon?

    Scientists say they have definitive evidence for water ice on the surface of the Moon. The ice deposits are found at both the north and south poles, and are likely to be ancient in origin.

    The result comes from an instrument on India's Chandrayaan-1 spacecraft, which explored the Moon between 2008 and 2009. Details of the work have been published in the journal Proceedings of the National Academy of Sciences (PNAS). The distribution of the ice deposits is patchy. At the lunar south pole, most of the ice is concentrated in craters. At the northern pole, the water-ice is both more sparse and more widely spread. The Moon Mineralogy Mapper (M3) instrument aboard Chandrayaan identified three specific signatures of water-ice at the lunar surface.

    M3 not only picked up the reflective properties one would expect from ice, but was able to directly measure the distinctive way its molecules absorb infrared light. This meant that M3 could differentiate between liquid water and vapour and solid ice. Temperatures on the Moon can reach a searing 100C in daytime, which doesn't provide the best conditions for the survival of surface ice. But because the Moon is tilted on its axis by about 1.54 degrees, there are places at the lunar poles that never see daylight.

  11. When will NASA go to the Moon again?

    The unmanned Orion probe, currently under development, will blast off into space atop NASA’s Space Launch System (SLS) for a three-week lunar voyage. Orion will journey more than 40,000 miles (64,373 km) beyond the dark side of the Moon before the NASA craft returns home.

    Exploration Mission-1 (EM-1) will be the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida. The first in a series of increasingly complex missions, EM-1 will be an uncrewed flight test that will provide a foundation for human deep space exploration, and demonstrate NASA’s commitment and capability to extend human existence to the Moon and beyond.

  12. Where is the scope for life on the Moon?

    Scientists have found ice scattered across the Moon's surface. And it's a discovery that surely could have major consequences for other things up there, too.

    So, across the surface of our nearest neighbour is frozen ice, hiding out in places in the polar regions that aren't touched by the sun. The breakthrough has prompted discussion a moon village that could allow people to live on the moon.

    From there, we could launch into the rest of our neighbourhood, providing vast new opportunities for space exploration. And, as ever, it has prompted discussion of whether the water spread throughout our Solar System might mean alien life is living far nearer to us than we think.

    Does it mean there might be aliens?

    Probably not. NASA's ruling principle in its search for aliens has been to follow the water, since that is thought to be required for any kind of life, but that doesn't necessarily mean that life exists everywhere water does. The environment on the Moon is still unremittingly harsh. It is freezing cold in the shade where the ice is, and devastatingly hot out of it; almost certainly too difficult for life. And that's not to get started on the radiation that pounds the Moon's surface. Of course, we can't say for sure there aren't aliens; nobody can, until we've scoured the entire Moon.

    There might be forms of life that look entirely different to what we expect, and which are able to live in very harsh environments – we have certainly found such organisms down here on Earth. There are much better moons to go hunting for aliens on in our own solar system, anyway.

  13. Who is preparing for a second lunar journey?

    India will launch its second lunar mission on January 3 next year, which will land on the moon with a lander and rover. “We are aiming to launch the mission on January 3 next year, but the window to land on the lunar surface is open till March 2019,” Indian Space Research Organisation (ISRO) chairman K Sivan told reporters in Bengaluru.

    The Rs 800-crore ($114 million) lunar mission named “Chandrayaan-2” comes over a decade after India went up to the lunar orbit on November 8, 2008 after the “Chandrayaan-1” launch on October 22 onboard a Polar Satellite Launch Vehicle (PSLV) rocket from the spaceport in Sriharikota in Andhra Pradesh.

    The 3,890-kg Chandrayaan-2, which will be launched onboard the Geosynchronous Satellite Launch Vehicle (GSLV) Mk-3, will orbit around the moon and study its lunar conditions to collect data on its topography, mineralogy and exosphere.

    A lander with rover, which will separate from the spacecraft, will orbit the moon, and then gradually descend on the lunar surface at a designated spot. The rover’s instruments will observe and study the lunar surface. The lander has been named “Vikram” as a tribute to the pioneer of India’s space program and former ISRO chairman (1963-71), Vikram Sarabhai, Sivan said.

    This is the first time India will have a rover landing on the moon nearly 50 years after American astronaut Neil Armstrong walked on the eerie lunar surface in 1969. The Indian space agency, which was targeting the second lunar mission this year, has had to make design and functional changes to Chandrayaan-2, causing the delay and pushing the mission to January next year. For its Chandrayaan-1, ISRO had carried a moon impact probe vehicle to crash land on the surface from the lunar orbit.

  14. Just how wrong can we be about alien life?

    Days before Mars was scheduled to record the closest distance from Earth in 15 years, scientists reported having spotted a sizable salt-laden lake under the ice on the southern polar plain of Mars, a body of water that raises hopes that more water — and maybe even primitive life — exists on the Red Planet. The reservoir that was detected — about 20 kilometres in diameter, shaped like a rounded triangle and located 1.5 kilometres beneath the ice surface — represents the first and the largest stable body of liquid water ever found on Mars, said the report in the journal Science. "Water is there. We have no more doubt," co-author Enrico Flamini, the Italian space agency's Mars Express mission manager, said.

    Any hint of any amount of water present in any form on any planet or its satellite gets people and scientists alike. But there is no need for that excitement. Just because you cannot survive without water does not mean the aliens cannot either.

    When scientists say they are looking for ‘life’, or the conditions for ‘life’ on Mars or elsewhere in the universe, they assume that ‘life’ anywhere else is going to be similar to what it is on Earth, when alien life forms would have developed in environments completely different from ours and therefore not require what we assume to be substances ‘essential for life’.

    Scientists have speculated that some life in the universe could be based on silicon rather than carbon, but in the universe, carbon is about 15 times more abundant than silicon. Maybe some life forms are not based on water, but are based on other liquids such as the methane/ethane lakes of Titan.

    Most scientists begin with what they are most familiar with: water and carbon-based life. They make this assumption not because they think this is the only possibility, but because this is what they know how to look for. Just like you look under the lamp post for your keys not because that is the only place you could have lost them, but because that is the only place where you can see anything. As scientists, their job is to invent new instruments and move the lamp post so they can look further afield.

    Our best guesses about the nature of life elsewhere probably come from the most fundamental features of life on Earth. These include, carbon-based chemistry and water as the liquid. But even life that is not based on carbon or water will require some source of energy, such as light from the Sun or chemical energy at hydrothermal vents at the bottom of the ocean.

    When scientists speculate about the kind of life that might exist in the newly discovered lake beneath the south polar cap of Mars, they assume that it will need a source of energy. When they do science they have to use instruments with limitations. They have to use the instruments that are available. If their assumptions are wrong, then their instruments will be inappropriate. That might leave them looking for polar bears in the tropics. If so, they will find nothing and move on.

    Maybe with a new instrument they can look for grizzly bears in the tropics. That is how science moves forward.
