ISRO's 20-in-1 mission successful


PSLV-C34 lifts off with satellites from Satish Dhawan Space Centre; a look at top 10 facts

The Indian Space Research Organisation (ISRO) on Wednesday set a new record of launching 20 satellites, including India’s Cartosat-2 series and those the U.S., Germany, Canada and Indonesia.
At 9:26 a.m., ISRO’s workhorse PSLV C-34 lifted off from the Satish Dhawan Space Centre at Sriharikota.

PSLV performs tricky experiments
The vehicle will not only put 20 satellites into the same orbit — the highest number of satellites to be put into orbit by a PSLV — but it will perform two tricky experiments of the same nature. Fifty minutes after the satellites are injected into the orbit from the fourth stage of the vehicle, its engine will be re-ignited for five seconds. Then it will be shut down for 50 minutes and re-ignited for another five seconds, according to K. Sivan, Director, Vikram Sarabhai Space Centre, Thiruvananthapuram.Continue reading…
Top 10 facts:
» India’s earth observation spacecraft Cartosat-2 Series satellite and 19 co-passenger satellites together weighing about 560 kg at lift-off would be injected into a 505 km polar Sun Synchronous Orbit.
» The primary satellite to be carried by PSLV C-34 rocket is similar to Cartosat-2, 2A and 2B satellites launched earlier. The imagery to be sent by the satellite would be useful for cartographic applications, coastal land use and regulation, utility management like road networking, water distribution, creation of land use maps, precision study, change detection to bring out geographical and manmade features and various other Land Information System and Geographical Information System applications.
» LAPAN-A3 (Indonesia): The microsatellite is for Earth observation and is intended to be used to monitor land use, natural resource and environment.
» M3MSat (Canada): Maritime Monitoring and Messaging Micro-Satellite is a technology demonstrator mission jointly funded and managed by Defense Research and Development Canada (DRDC) and the Canadian Space Agency (CSA). The satellite’s primary mission is to collect and study Automatic Identification System signals from low-Earth orbit.
» GHGSat-D (Canada): Built by Space Flight Laboratory of the University of Toronto Institute for Aerospace Studies, the Earth observation satellite is meant for measuring the atmospheric concentration of greenhouse gases (Carbon Dioxide and Methane).
» BIROS (Germany): Berlin Infrared Optical System (BIROS) is a small scientific satellite from the German Aerospace Center and its mission objective is the remote sensing of high temperature events.
» SkySat Gen2-1 (U.S.): Designed and built by Terra Bella, a Google company based in Mountain View, California in the U.S., the small Earth imaging satellite is capable of capturing sub-meter resolution imagery and HD video.
» Dove Satellites (U.S.): A total of 12 Flock-2P Earth imaging satellites are to be launched in this mission. They would be packed in three dispensers.
» Sathyabamasat (Sathyabama University, Chennai): The satellite aims to collect data on green house gases.
» Swayam (College of Engineering, Pune): The satellite aims to provide point to point messaging services to the HAM (amateur radio) community.
