Those TV broadcast banners that take up the bottom third of the screen really don't work with tall skinny rockets, do they? Perhaps they could compromise, filling the sides of the screen, rather than the bottom, when they're covering a rocket launch! - Ed Kyle
^ How can the booster be in a initial higher orbit than the s/c? where the booster engines fired again after releasing the s/c ?
April 28, 2012Radar 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 transmits its own radar pulses (at 5.35 GHz) to study the objects on Earth. This facilitates cloud penetration andimaging even without sunlight. For RISAT-1, imaging sessions around both 6 AM and 6 PM have been chosen.
