 India’s heaviest, largest and most powerful satellite GSAT-11 was successfully launched by an Arianespace rocket from the French Guiana. Blasting off from the Ariane Launch Complex in Kourou, the Ariane-5 vehicle injected the GSAT-11 into the orbit in a flawless flight lasting about 33 minutes. The satellite will play a vital role in providing broadband services across the country and also be a platform to demonstrate new generation applications. As per the ISRO Chairman K Sivan, GSAT-11 is going to be the richest space asset for India and it will provide something like 16 Gbps data link services to the country.
About GSAT-11 in Brief:  The satellite has 38 spot beams as well as eight sub-beams, which will cover the entire country, including the remote places.
  • Launch Mass: 5854 kg.
  • Mission Life: 15 Years.
  • Power: 13.6 kW Ariane-5 VA-246.
  • Type of Satellite: Communication.
  • Manufacturer: ISRO.
  • Application: Communication.
  • Orbit Type: GTO.

 The Indian Space Research Organisation (ISRO) has successfully launched PSLV-C43.This launch took place from the first launch pad of the Satish Dhawan Space Centre in Sriharikota. Marking the 45th mission that uses the polar satellite launch vehicle (PSLV) rocket, ISRO launched its latest Earth-mapping satellite, HysIS, as part of the mission. The HysIS satellite adds a mass of 360kg to the payload, and launched beside 30 other satellites from eight nations. Out of these, 23 are from the United States. These smaller satellites will add a weight of 281.4kg to the payload, and adds to ISRO’s list of 239foreign satellites that have already been launched.

 University Grants Commission, UGC has decided to set up a Consortium of Academic and Research Ethics (CARE) which will prepare a fresh list of credible quality journals in the non-science disciplines. The commission stated that the percentage of research articles published in poor quality journals is reported to be high in India which has adversely affected its image. CARE will be headed by the UGC Vice Chairman. Members of CARE will prepare lists of quality journals in their respective disciplines within a defined timeframe. These lists will be critically analysed and curated for quality by a special cell at the entrusted institution using defined criteria. Reference List of Quality Journals’ will be maintained by the CARE and this will be used for all academic purposes.

 NASA’s InSight spacecraft landed on Mars after nearly a 7 months, 458-million-kilometre journey, and a 6.5-minute parachuted descent through the Red Planet’s atmosphere. The 360-kg lander also shared its first photo from Mars, showing an area called Elysium Planitia, where it will dig five meters below the surface. The $993-million mission will measure the Mars’ internal heat and study quakes.

 GSAT-29 communication satellite, which is being carried by Indian Space Research Organisation (ISRO)’s Geosynchronous Satellite Launch Vehicle (GSLV-Mk III) was launched into space. The satellite aims at solving the communication barriers faced by Village Resource Centres (VRCs), which are responsible for providing space-based services to ISRO from rural areas.
The launch took place from the Satish Dhawan Space Centre in Sriharikota. The GSAT-29 is a communication satellite with a weight of 3,423 kg. According to ISRO, this will be the second developmental flight of GSLV-Mk III rocket with a rated carrying capacity of four tonnes. GSAT-19 was the first of the series that was sent up into the orbit in June 2017.
