First day Images from Cartosat -2 Series Satellite



Cartosat-2 is an advanced remote sensing satellite with a single panchromatic camera (PAN) capable ofproviding scene-specific spot imageries for cartographic applications. The camera is designed to provide imageries with better than one meter spatial resolution and a swath of 10 km. The satellite will have high agility with capability to steer along and across the track up to + 45 degrees. It will be placed in a sun-synchronous polar orbit at an altitude of 630 km. It will have a revisit period of four days. The re-visit can be improved to one day with suitable orbit manoeuvres.
                           
                                      
Several new technologies like two mirror on axis single camera, Carbon Fabric Reinforced Plastic based electro optic structure, lightweight, large size mirrors, JPEG like data compression, advanced solid state recorder, high-torque reaction wheels and high performance star sensors are being employed in Cartosat-2.
Cartosat-2 suffered from some problems after launch. An improved Cartosat 2A was launched in 2008. Cartosat 2Bfollowed in 2010.
                                         
                               Beginning with Cartosat 2C, a Multi-spectral camera was added and a lower 505 km orbit for better ground reslution was introduced.

                             
Cartosat 2C was launched in June 2016. Cartosat 2D will follow in February 2017 and Cartosat 2E is planned for late 2017

Location: Kottarakkara, Kerala, India

ISRO to Launch Record 83 Satellites on a Single Rocket

ISRO to Launch Record 83 Satellites on a Single Rocket ISRO Tuesday said it would launch a record 83 satellites in one go using its workhorse PSLV-C37 toward the end of January. "We are working for a January launch. It will be toward the end of January. The date has to be fixed," Indian Space Research Organisation Chairman A S Kiran Kumar told reporters in Bengaluru. Of the 83 satellites, 80 belong to Israel, Kazakhstan, Netherlands, Switzerland and the US. They weigh about 500kg. The three Indian satellites are Cartosat-2 series, weighing 730kg as primary payload, and INS-IA and INS-1B, weighing 30kg. Setting a record in its space programme, ISRO in June had successfully launched 20 satellites, including its earth observation Cartosat-2 series, in a single mission on board PSLV-C34 from the spaceport in Sriharikota in Andhra Pradesh. The space agency had earlier sent 10 satellites into orbit in a single mission in 2008. Calling 2016 a "good"

VAINU BAPPU Father of Modern Indian ASTRONOMY

Image
Manali Kallat Vainu Bappu  (August 10, 1927 – August 19, 1982) was an  Indian  astronomer and president of the  International Astronomical Union . Bappu helped establish several astronomical institutions in India——including the  Vainu Bappu Observatory  named after him—and also contributed to the establishment of the modern  Indian Institute of Astrophysics . In 1957, he discovered the  Wilson-Bappu effect  jointly with  American  astronomer  Olin Chaddock Wilson . He is regarded as the father of modern Indian astronomy. Manali Kallat Vainu Bappu Vainu Bappu was born in an Thiyya family on August 10, 1927, in  Chennai , as the only child of Manali Kukuzhi and Sunanna Bappu.His family originally hails from  Thalassery  in  Kerala . His father was an astronomer at the Nizamiah Observatory in  Andhra Pradesh .He attended the  Harvard Graduate School of Astronomy  for his  PhD  after obtaining postgraduate degree from the  Madras University . Bappu, along with two of his

Astronomy

ജ്യോതിഃശാസ്ത്രം Astronomy  is a natural science which is the study of celestial objects (such as stars, galaxies, planets, moons, asteroids, comets and nebulae), the physics, chemistry, andevolution of such objects, and phenomena that originate outside the atmosphere of Earth, including supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. A related but distinct subject, physical cosmology, is concerned with studying the universe as a whole. Astronomy is one of the oldest sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and  Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astr
