ISRO lauches INSAT 3DR using indigenous engine denied by Russia

       ISRO makes India proud again with successful launch of its INSAT-3DR, an advanced weather satellite, which was placed in orbit around 17 minutes after GSLV-F05 took off from Satish Dhawan Space Centre in Sriharikota at 4.50pm. The GSLV – F05 was propelled by a indigenous cryogenic engine – upper stage.

      Cryogenic engine are the ones which has capability to out heavy (2000 KG ) satellites to geostationary orbits (36,000 Kms above ground). Twenty years ago, Russia used to supply this engines for our satellite launches. Owing to geopolitics, after intervention from USA, the super critical engines were denied to us. Starting in the mid-1990s, ISRO has developed its own cryo engine and has tested it on three vehicles since 2010. The latest one is upper stage which is the first time used for operational launch.  Previous launches were developmental. An operational flight means ISRO will not be testing any components, flight parameters or flight routes. The launch will solely be about the mission: delivering the payload.

INSAT 3D

  The 2,211kg INSAT – 3DR satellite, which will provide meteorological and search and rescue data services to the country, was injected into the geostationary transfer orbit. The satellite, with the help of its propellant, will be raised to the final geostationary orbit after two days.

    It can be used to predict weather conditions, rainfall and communicate during severe weather conditions. It can provide information about radiation, sea surface temperature, snow cover, cloud motion and fog

ISRO is doing a wonderful job for a while and we all INDIANS should be proud of it.

       India’s space agency ISRO placed 20 satellites in space recently at one go , more than half are for US, only 3 for India. ISRO’s efforts makes India compete for bigger share of $300 billion global space industry.

ISRO’s PSLV-C34

All You Need To Know about ISRO’s recent launch:

  • The maximum number of satellites that ISRO has been able to launch in a single mission so far is ten. This was achieved in June 2008 when it placed those satellites into various low earth orbits. The idea behind launching so many satellites is reducing cost of the mission.
  • The rocket’s main cargo is India’s 725.5 kg Cartosat-2 series satellite for earth observation. This satellite is similar to the earlier Cartosat-2, 2A and 2B. The images sent by Cartosat satellite will be useful for cartographic, urban, rural, coastal land use, water distribution and other applications.
  • Chennai’s Sathyabama University and College of Engineering, Pune have also sent up one satellite each with PSLV-C34.
  • The Cartosat will take more than half of the weight of all the payloads put together. The rest of the satellites weighed about 560 kg at lift–off.
  • The total weight of all the satellites on the rocket is 1,288 kg. Thirteen of the satellites are from USA including the 12 Dove satellites from Planet Labs organisation, each of which weighs just 4.7 kg. There are two Canadian satellites and one each from Germany and Indonesia.
  • According to ISRO, the 110 kg SkySat Gen2-1 belonging to Terra Bella, which is owned by Google. The small earth imaging satellite can capture sub-metre resolution imagery and high definition video.
  • The 1.5 kg Sathyabamasat from Sathyabama University will collect data on greenhouse gases while the 1 kg Swayam satellite from College of Engineering, Pune will provide point-to-point messaging services to the HAM radio community.
  • Till date India has launched 57 foreign satellites successfully.
