Former ISRO Chariman UR Rao becomes first Indian to be inducted into IAF Hall of Fame

Former ISRO Chairman and space scientist Prof Udupi Ramachandra Rao became the first Indian to be inducted in the Hall of Fame of International Astronautical Federation (IAF).

He was inducted during the closing ceremony of the 67th IAF Congress 2016 held at Guadalajara, Mexico for his outstanding contribution to the progress of astronautics.

About UR Rao

  • He had served as Chairman of Indian Space Research Organisation (ISRO) from 1984 to 1994.
  • Under his guidance, ISRO had designed more than 20 satellites including India’s first satellite Aryabhatta.
  • Under his leadership, India had initiated the development of the geostationary launch vehicle GSLV and the development of cryogenic technology in 1991.
  • He was also responsible for successful launch of INSAT satellites during his stint at ISRO.
  • He also had served as the first Chairman of Antrix Corporation, the commercial arm of the ISRO. He has published more than 260 scientific and technical papers in various journals.
  • He had played pivotal role in promoting the use of space technology for broadcasting, meteorology, education, disaster warning and remote sensing.
  • Awards and Honours: Padma Bhushan (1976). He was inducted into the Satellite Hall of Fame, Washington in March 2013 by the Society of Satellite Professionals International.

IAF Hall of Fame: It consists of a permanent gallery of these personalities, including biographical information, citation and a picture in a special part of the IAF web presence.

ISRO successfully launches 8 satellites into two different orbits

The Indian Space Research Organisation (ISRO) for first time has successfully launched eight satellites into two different orbits in a single mission.

These satellites were launched onboard of Polar Satellite Launch Vehicle C35 (PSLV C35) from the first launch pad of the Satish Dhawan Space Centre, Sriharikotta.

It was PSLV’s longest and most complex mission. It is also for the first time PSLV has successfully placed satellites in two different orbits in single mission.

Key Facts

  • Among the eight satellites launched, three satellites were from India, three from Algeria and one each from Canada and United States.
  • SCATSAT-1 satellite of India weighing 371 kg was the primary payload and remaining other seven customer satellites were secondary payloads (5 foreign and 2 domestic satellite) weighing 304 kg in total.
  • SCATSAT-1 satellite: It is weather satellite that was placed in polar sun synchronous orbit of 730 kilometer height.
  • It will provide weather forecasting services meant for ocean and weather forecasts, cyclone detection and tracking through wind-vector products. It will have life of five years.
  • Pratham: It is a 10-kg satellite developed by students from Indian Institute of Technology (IIT), Bombay.
  • It will be used to study the total electron count in space with a resolution of 1km x 1km location grid.
  • PISAT: It is a 5.25-kg satellite made by students of Bengaluru’s PES University. It will take pictures of earth for remote sensing applications.
  • Three Algerian satellites: Alsat-1B (103 kg), Alsat-2B (110 kg) and Alsat Nano (7 kg). They will be used for remote sensing, earth observation, and technology demonstration.
  • Pathfinder-1: It is US satellite owned by BlackSky. It weighs 44 kg and has a high resolution imaging microsatellite.
  • NLS-19: It is Canadian satellite developed by University of Toronto. It is a nano-satellite weighing 8 kg. It will be used for experiments for reducing space debris.

Comment

  • It was longest and most complex mission because most countries launch satellites in a single orbit and even if multiple satellites are injected in a sequence in the same orbit.
  • However, in this mission PSLV launched its payloads in two different orbits by following twin-orbit manoeuvre. It was recently accomplished by European Space Agency’s Vega rocket.
  • This is a challenging two-in-one mission also puts India in a unique league of nations having the capability to achieve two different orbits in a single mission.
  • This successful mission also has enhanced marketability and versatility of PSLV, ISRO’s workhorse and also increased its unique position global satellite launch services market.
