Bhuvan gives you an easy way to experience, explore and visualize IRS images over Indian region.
ISRO is well known amongst space faring nations for its world-leading reputation in developing new, indigenous and innovative service oriented applications using remote sensing technology.
Over the past 2 decades, ISRO has mastered the art of developing these unique applications using various spectral, spatial and temporal resolutions offered by the versatile IRS satellites and these have been successfully institutionalized in many important areas of policy making, natural resources management, disaster support, and enhancing the quality of life across all sections of the society.
Bhuvan, an ambitious project of ISRO
Bhuvan is an initiative to showcase this distinctiveness of Indian imaging capabilities including the thematic information derived from such imagery which could be of vital importance to common man with a focus on Indian region. Bhuvan, an ambitious project of ISRO to take Indian images and thematic information in multiple spatial resolutions to people through a web portal through easy access to information on basic natural resources in the geospatial domain.
Bhuvan showcases Indian images by the superimposition of these IRS satellite imageries on 3D globe. It displays satellite images of varying resolution of India’s surface, allowing users to visually see things like cities and important places of interest looking perpendicularly down or at an oblique angle, with different perspectives and can navigate through 3D viewing environment.
The degree of resolution showcased is based on the points of interest and popularity, but most of the Indian terrain is covered upto at least 5.8 meters of resolution with the least spatial resolution being 55 meters from AWifs Sensor. With such rich content, Bhuvan opens the door to graphic visualisation of digital geospatial India allowing individuals to experience the fully interactive terrain viewing capabilities.
Bhuvan brings a whole lot of uniqueness
Multi-resolution images from multi-sensor IRS satellites of India is seamlessly depicted through the Bhuvan web portal by enabling a common man to zoom into specific area of interest at high resolution. Bhuvan brings a whole lot of uniqueness in understanding our own natural resources whilst presenting beautiful images and thematic vectors generated from varieties of geospatial information.
Bhuvan will also attempt to bring out the importance of multi-temporal data and to highlight the changes taking place to our natural resources, which will serve as a general awareness on our changing planet.
There are lot more special value added services which will be enabled onto the web portal in due course of time and each one of those services are going to be unique to preserving and conserving our precious natural resources through public participation. We are sure the common man will get rich benefits from these Indian geospatial data services in days to come.

Laurels for India on successful moon landing
France, chair of the 27-nation European Union has lauded India on the successful lunar exploration mission, which, it stressed, confirmed "India's eminent position among the world-class scientific and technological powers".
"France, on behalf of the European Union, warmly congratulates India for the successful landing of the Moon Impact Probe and the launch of the lunar exploration programme," the French embassy said in a statement here.
"This remarkable success of the Indian space vehicle confirms anew India's eminent position among the world-class scientific and technological powers," it said.
"France and the European Union look forward to the strengthening of the existing scientific cooperations with India in the field of space, which are particularly promiseful for the development of science and knowledge worldwide," the statement underlined.
In a milestone for the country's space programme, India planted its national colours on the moon Thursday as the foil-wrapped Moon Impact Probe landed in the Shakelton crater near the lunar South Pole.
The Moon Impact Probe, dropped from the larger, unmanned Chandrayaan-1 orbiter, sampled the thin lunar atmosphere during a half-hour free fall.
Chandrayaan-1, India's first unmanned lunar probe, was launched Oct 22. After the US, then USSR, and Japan, India is the fourth country to land a probe on moon.

Chandrayaan-1 reaches final orbit
Destination Moon
It is yet another historic day in India’s space odyssey. Chandrayaan-1 successfully reached its intended operational orbit at a height of about 100 km from the lunar surface. This followed a series of three orbit reduction manoeuvres during the past three days by repeatedly firing the spacecraft’s 440 Newton Liquid Engine.
As part of these manoeuvres, the engine was fired totally for about 16 minutes. As a result, the farthest point of Chandrayaan-1’s orbit (aposelene) from the moon’s surface was first reduced from 7,502 km to 255 km and finally to 100 km. The nearest point (periselene) was reduced from 200 km to 182 km and finally to 100 km.
With this, the carefully planned complex sequence of operations to carryChandrayaan-1 from Earth orbit to operational lunar orbit has been completed. During these operations, Chandrayaan-1’s liquid engine, built by Liquid Propulsion Systems Centre (LPSC), Thiruvananthapuram, was fired ten times. In its current orbit, Chandrayaan-1 takes about 2 hours to go round the moon once.
From this orbit passing over the moon’s polar regions, it will conduct chemical, mineralogical and photogeological mapping with 11 instruments (payloads). Two of them — Terrain Mapping Camera (TMC) and Radiation Dose Monitor (RADOM) — have already been successfully switched on. TMC has taken pictures of the Earth and the moon.
The next major event of the mission is the release of the Moon Impact Probe (MIP) and its landing on the moon’s surface.

After Moon, ISRO plans mission to Sun
After the Chandrayaan-I moon odyssey, it's 'Mission Sun' for the Indian Space Research Organisation.
Scientists at ISRO are in the advanced stage of designing a spacecraft, named 'Aditya', to study the outermost region of the Sun called corona.
"That's a mini satellite. In fact, the design is just getting completed," ISRO Chairman G Madhavan Nair told PTI.

"During solar maxim...which is happening...we would like to see the type of emissions which are taking place in the Sun and how it interacts with the ionosphere and atmosphere and so on," he said.
According to Dr Jayati Datta, deputy programme director, Space Science Office, ISRO, Aditya is the first space basedSolar Coronagraph intended to study corona.
'Aditya' would be the first attempt by the Indian scientific community to unravel the mysteries associated with coronal heating, coronal mass ejections and the associated space weather processes and study of these would provide important information on the solar activity conditions, she said.
We will have total map of the moon, says ISRO
"A basic understanding of the physical processes and continuous monitoring would help in taking necessary steps towards protecting ISRO's satellites either by switching them off or putting them on a stand-by mode as warranted by the background conditions," Datta aaid.
The temperature of the solar corona goes beyond a million degrees. From the Earth, corona can be seen only during total solar eclipses, mainly due to the bright solar disc and the scattering of the sunlight by the Earth's atmosphere. One has to go beyond the atmosphere to be able to mask the bright solar disc and study the corona.
Chandrayaan may reveal moon mysteries
The space borne coronagraph 'Aditya' in would study the Coronal Mass Ejection and consequently the crucial physical parameters for space weather such as the coronal magnetic field structures, evolution of the coronal magnetic field etc, Datta said.
"Completely new information on the velocity fields and their variability in the inner corona, having an important bearing on the unsolved problem of heating of the Corona, would be obtained," she explained.
Activities towards 'Aditya Mission' have been initiated with the involvement of scientists from ISRO centres and prime national research institutes in the country.

ISRO is planning to launch 'Aditya Mission' during the next high solar activity period. However, the exact date/time is not yet confirmed. "Aditya' is an indigenous/Indian mission. So far, there is no plan of putting any foreign payload on board Aditya mission," Datta said, adding that the United States, the European Space Agency and Japan [Images] have flown missions to study Sun and solar corona/activities.
The sun, which is highly turbulent and dynamic, sends out large chunks of charged particles and emits highly energetic electromagnetic radiation in all directions.
These radiations, on reaching Earth, cause severe near-Earth-space disturbances called Geomagnetic storms, which affect communication links, disturb power lines in high altitudes, cause aurora in polar regions and affect satellite systems directly and also indirectly through changes brought about in the near Earth atmosphere.

Chandrayaan dips lower in moon orbit
India's first unmanned lunar spacecraft Chandrayaan-1 was pushed further towards the moon's surface in the first orbit-lowering manoeuvre late Sunday, a top space agency official said.
India's first unmanned lunar spacecraft Chandrayaan-1 was pushed further towards the moon's surface in the first orbit-lowering manoeuvre late Sunday, a top space agency official said.
'The first orbit lowering operation was carried out successfully at 20.03 hrs IST by firing the liquid engine onboard the spacecraft for 57 seconds. All systems are functioning satisfactorily,' Indian Space Research Organisation (ISRO) Director S. Sathis told IANS here.
In this elliptical orbit, Chandrayaan will be circling the moon over its polar regions at 200 km periselene (nearest point from moon) and 7,500 km aposelene (farthest point from moon).
'Further orbital manoeuvres are planned over the coming days to lower the spacecraft gradually to its designated slot of 100x100 km from the lunar surface for conducting various experiments, including high resolution remote sensing of the moon,' Satish said.
The operation was carried from the spacecraft control centre of the space agency's telemetry, tracking and command network (Istrac) here along with its deep space network (DSN) at Byalalu, about 40 km from this tech hub.
Chandrayaan was successfully put into the lunar orbit Saturday after an 18-day voyage, making it the first ever Indian-built spacecraft to break away from the earth's gravitational field and get captured by the moon's equally powerful gravity.
Chandrayaan carries 11 scientific instruments, including six foreign payloads - two from the US, three from the European Space Agency (ESA) and one from Bulgaria. The remaining five are indigenously designed and developed by various centres of the state-run ISRO.
The spacecraft was blasted off Oct 22 onboard the 316-tonne polar satellite launch vehicle (PSLV-C11) from the Satish Dhawan space centre at Sriharikota spaceport, about 80km north of Chennai.
