ISRO AT ITS BEST

By
PSLV-C31
Polar Satellite Launch Vehicle, in its 33rd  flight (PSLV-C31), launches IRNSS-1E, the fifth satellite of the Indian Regional Navigation Satellite System (IRNSS). The launch took place from the Second Launch Pad (SLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.  As in the previous four launches of IRNSS satellites, PSLV-C31 uses ‘XL’ version of PSLV. This is the eleventh time ‘XL’ configuration was flown, earlier ten being PSLV-C11/Chandrayaan-1, PSLV-C17/GSAT-12, PSLV-C19/RISAT-1, PSLV-C22/IRNSS-1A, PSLV-C25/Mars Orbiter Spacecraft, PSLV-C24/IRNSS-1B, PSLV-C26/IRNSS-1C, PSLV-C27/IRNSS-1D, PSLV-C28/DMC-3 and PSLV-C30/ASTROSAT  mission .

IRNSS-1E
IRNSS-1E is the fifth navigation satellite of the seven satellites constituting the IRNSS space segment. Its predecessors, IRNSS-1A, 1B, 1C and 1D were launched by PSLV-C22, PSLV-C24, PSLV-C26 and PSLV-C27 in July 2013, April 2014, October 2014 and March 2015 respectively. IRNSS-1E has a lift-off mass of 1425 kg. The configuration of IRNSS-1E is similar to that of IRNSS-1A, 1B, 1C and 1D. 
IRNSS -1E carries two types of payloads – navigation payload and ranging payload. The navigation payload of IRNSS-1E will transmit navigation service signals to the users. This payload will be operating in L5-band and S-band. A highly accurate Rubidium atomic clock is part of the navigation payload of the satellite. The ranging payload of IRNSS-1E consists of a C-band transponder which facilitates accurate determination of the range of the satellite. IRNSS-1E also carries Corner Cube Retro Reflectors for laser ranging.
PSLV-C31 Successfully launches IRNSS-1E  on January 20, 2016 at 09:31 Hrs (IST) from Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, the spaceport of India.

A new planet out there?

By
On Jan. 20, 2016, scientists announced the discovery of what could be a giant planet in the Kuiper Belt at the outer edge of our solar system. Nicknamed "Planet Nine," the world is a behemoth - about 10 times the mass of the Earth. It would take the planet between 10,000 and 20,000 years to orbit the sun. The evidence for existence of Planet-9. Evidence for Planet Nine was unveiled by researchers Mike Brown and Konstantin Batygin at the California Institute of Technology in Pasadena, California. The scientists used mathematical modeling and computer simulations to make the find, but have not actually observed the planet directly.

Dark Matter

Dark matter , doesn't the word relates to something mysterious out there?, Something which is revolving around our minds? Well actually it does!. The question that comes into the mind is "what do we mean by dark matter"? Dark matter refers to the hypothetical invisible substance in the universe. The universe has fixed shape(as it can be curved by mass) , so where did this mass come from? We know that galaxies also have a fixed shape ,though it changes slightly, but the overall picture seems to be more or less similar because they are bound to that shape. This shape, the curve due to mass, the "extra mass" all this points to something that is missing out there!! this is referred to as dark matter. Dark because  it is invisible to us and matter because it has mass and occupies the empty space in the universe and provides those galactic bodies a support structure. The distribution of the content of the universe. source : Google Now the term dark energy ...
