Is it some kind of magic or the gift which god provided to us for inducing life? Is it a special quality which belongs to only certain living beings or is it spread across the whole universe uniformly? In this paper we travel across the Universe and our thoughts and fathom the Consciousness

Over the past few years, real-time 3D shape measurement technologies have been advancing drastically rapidly.One of the Main technique in the 3D profile measurment is by using Structured Light. Here we project a structured light on a surface and take an image of structured light on the surface for retrieval of phase which inturn will help in 3D Profile retrieval. In this project, Various Phase retrieval methods of optical fringe projection techniques are tested.The Pros and Cons of the techniques have been analysed. A Novel way of unwrapping the wrapped phase obtained after phase extraction from the fringes using unscented kalman filter has been analysed,studied and implemented. Various simulations and examples are also attached to compleme...

The launch vehicle - PSLV-C25 successfully injected the Spacecraft into an Elliptical Parking Orbit around earth. It was a near perfect launch for the Mangalyan spacecraft, the 25th successful mission carried out by the PSLV rocket, the trusted workhorse of ISRO. The spacecraft first going into orbit around the earth signalled the start of its 300-day voyage to the Red Planet. If everything goes well during this complex and challenging journey through deep space, it will be put into the Mars orbit on September 24, 2014. The orbiter weighs about 1,350 kg and will carry five instruments to conduct a battery of remote-sensing experiments on the availability of methane on the Red Planet, its upper atmosphere, its surface features, mineralogy and so on. One of the main objectives of the first Indian mission to Mars is to develo...

the Satish Dhawan Space Centre at Sriharikota at 2.38 pm. The launch vehicle - PSLV-C25
successfully injected the Spacecraft into an Elliptical Parking Orbit around earth. It was a near
perfect launch for the Mangalyan spacecraft, the 25th successful mission carried out by the PSLV
rocket, the trusted workhorse of ISRO.
The spacecraft first going into orbit around the earth signalled the start of its 300-day
voyage to the Red Planet. If everything goes well during this complex and challenging journey
through deep space, it will be put into the Mars orbit on September 24, 2014. The orbiter weighs
about 1,350 kg and will carry five instruments to conduct a battery of remote-sensing
experiments on the availability of methane on the Red Planet, its upper atmosphere, its surface
features, mineralogy and so on.
One of the main objectives of the first Indian mission to Mars is to develop the
technologies required for design, planning, management and operations of an interplanetary
mission. From technological viewpoint, ISRO is looking at the mission that would help in
design and realisation of a Mars orbiter with a capability to survive and perform Earth bound
manoeuvres, cruise phase of 300 days, Mars orbit insertion / capture, and on-orbit phase around
Mars. It will also explore possibilities of deep space communication, navigation, mission
planning and management and incorporate autonomous features to handle contingency
situations.The scientific objectives which ISRO intends to achieve is the exploration of Mars
surface features, morphology, mineralogy and Martian atmosphere.
