SPOT6 reached to SHAR
The Satish Dawan Space Centre in Nellore district at Sriharikota will launching PSLV C-21 rocket(100th rocket) with French satellite SPOT6(800kg) and a small Japanese satellite weighing around 15kg in the month of September.This is the hundredth rocket in the 49 years of ISRO history.
Cabinet Clears Mars mission
The Union Cabinet on 03 August 2012 cleared the Indian Space Research Organization(ISRO) mission to Mars next year November The project envisages putting a spacecraft in the red planet’s orbit to study its atmosphere with the help of the polar Satellite launch vehicle. India joins the United states , Russia, Europe, Japan and China in undertaking such an
effort. The spacecraft will have a scientific payload of 25 kg and its proposed to be placed in an orbit of 500 x 80,000 km around the planet.The mission is estimated to cost about Rs $450 crore.
Curiosity Landed on Red Planet
The Robotic Explorer Curiosity blazed through the pink skies of mars, steering itself to gentle landing inside again crater for the most ambitious dig yet into the red planet. It was NASA’s seventh landing on earth’s Neighbor.In November 2011 American Space Research Centre NASA Launched the curiosity into the space. On 6 Aug 2012 the Curiosity landed safely on the Mars.The Voyage to Mars took more than eight months and spanned 352m million miles(566 million kilometers). It sliced through Martian atmosphere ay 13,000mph(21,000kph). The first of what scientists predict will be enormous
amounts of Information, Including a possible answer to whether Mars ever supported conditions for Organic life, to find evidence of life itself,alive or fossilized-its raft of 10 scientific instruments will hunt for carbon based compounds considered essential to microbial life. It stays 2 years in Mars to collect all these Information. This is the next space mission of NASA after 1970. Ashwini, Indo-American scientist involved in this mission.

A new oxidant in the atmosphere identified
Scientists have found for the first time unequivocal evidence of another oxidant playing a vital role in the formation of gaseous sulphuric acid in the atmosphere. Until now, it was thought that the combination of OH (hydroxyl radical) oxidant with sulphur dioxide (SO) was the dominant way by which gaseous sulphuric acid is formed in the atmosphere. They found the new oxidant has “significant capacity” to oxidise sulphur dioxide.
Largest 3D Map of Galaxies
Astronomers have unveiled the largest ever 3D map of the sky, encompassing massive galaxies and distance black holes, based on sloan digital sky survey III(SDSS- III). These galaxies are captures by a 2.5 meter wide -angle telescope located at the Apache Point observatory in New Mexico.The release Includes of 200 million galaxies and spectra of 1.35 million galaxies, according to a Harvardsmith soniam statement with SDSS-III.
Agni-II Test Fired Successfully
Surface to Surface missile Agni-II soared to a successfully test fired on 9 august 2012 at Wheeler Island of the Odisha. It have a height of 20km and weighted as 17 tonnes and have the capacity to carry a nuclear war head of weighing one ton. The missile Ranging Agni-I 700km , Agni-II 2,000 km , Agni- III-3,300km. The future projects are Agni 4 andAgni 5 to launch.
Print High Resolution Images Without Ink aNew Technology Developed
The team of scientists with Indian origin has developed a new technology of printing high resolution images without ink. The Institute of materials research and Engineering in Singapore has demonstrated that 1,00,000 dots per inch(dpi) can
produce sharp and full spectrum color images.Which can be applicable in reflect colour displays , anti-counterfeiting, and high density optical recording.Karthik Kumar says that size and spacing of the nanodots is critical to the final image quality. “The closer the dots are together and because of their small size, the higher the resolution of the image.
Nanotechnology for Solar panel efficiency
A University of Houston researchers has developed a nano particle coating for solar panel that makes it easier to keep them clean. This helps in keeping them efficient and cuts maintains cost. NASA spies cosmic supermom Scientists have found a cosmic supermom, a galaxy that gives birth to more stars in a day than Earth’s does in a year. Astronomers used NASA’s Chandra X-ray telescope to spot this distant gigantic galaxy creating about 740 new stars a year. By comparison,
our Milky Way Galaxy spawns just about one new star each year.
Prithvi-II missile test, a Success
The strategic Forces Command, which is in charge of nuclear weapons, successfully fired the surface to surface Prithvi-II missile from Chandipur in Odisha’s Balasore district on 25th August 2012, confirming yet again that the armed forces are
capable of launching nuclear missiles independently.
China Military test fires 14,000km range missile
The china central television(CCTV) reported that the china’s military had successfully tested the new 14,000 rang Dong feng-41 Intercontinental Ballistic Missile (ICBM). It have the capacity to carry 10 nuclear war heads.
Blue moon on 31st August 2012
When a full moon appears in the night sky for the second time in a calendar month ,it is called a ‘blue oon’.The next blue moon will occur on July 31,2015.
In US, India’s First C-17 transport aircraft takes shape
Now the Indian Air Force is planned to introduce a C-17 Globemaster III heavy lift military planes in place of old Cargo planes for the next year June. So India made deal with Boeing for $410 crores in the last year.C-17 has the capacity to fill oil in the air.
very usefull for me
