New research may help scientists accurately measure the mass of neutrinos for the first time.

New research may help scientists accurately measure the mass of neutrinos for the first time.
Neutrinos are the smallest known subatomic particles in the universe, and they're passing through the Earth (and your body) constantly.
This computer simulation shows a neutrino being detected at the Sudbury Neutrino Observatory in Canada, where researchers are trying to find out more about the tiny, mysterious particles. But the latest researchsuggests it may be better to measure the mass of neutrinos in space than the laboratory.

Radar Imaging Satellite (RISAT-1) successfully placed in its final orbit

The Radar Imaging Satellite (RISAT-1), launched by PSLV-C19 on April 26, 2012, has now been placed in its final Polar Sun-synchronous Orbit of 536 km height.
It may be recalled that PSLV-C19 had placed RISAT-1 in a polar orbit of 470 km X 480 km. As planned, on April 27-28, 2012, the satellite propulsion system was used in four orbital maneuvers to raise height of the orbit of RISAT-1 to 536 km. The satellite is now in its final orbital configuration and in good health.In the coming days, various elements of the C-band Synthetic Aperture Radar will be tested and calibrated as a prelude to payload operations.
As compared to the optical remote sensing satellites that depend upon sunlight, the Synthetic Aperture Radar of RISAT-1 transmitsits own radar pulses (at 5.35 GHz) to study the objects on Earth. This facilitates
1. cloud penetration and
2. imaging even without sunlight. For RISAT-1, imaging sessions around both 6 AM and 6 PM have been chosen
