Episode 92: Revisiting Panspermia with Prof. Wickramasinghe

By Gurbir Dated: January 1, 2021 Leave a Comment

Prof. Chandra Wickramasinghe

The idea of Panspermia, that life exists throughout the universe and spreads via asteroids, comets and cosmic dust, has been around for a long time. Two of the strongest advocates were Professor Fred Hoyle and Professor Chandra Wickramasinghe. 

In this episode I spoke at length with Professor Wickramasinghe about his long and distinguished career championing the idea of panspermia the covering the topics:

  • Initial difficulties in establishing Panspermia as a legitimate and respectable topic for scientific study.
  • Professor Wickramasinghe’s journey in 1960 form Cylon (as it was known at the time) to Cambridge as Hoyle’s Phd student.
  • His personal recollections of Fred Hoyle (initially his Phd supervisor and later collaborator) and Arthur C Clarke, who had made Cylon his home in the late 1950s.
  • His views on how the research on Panspermia has developed and where it stands today

Episode 69: Mars Orbiter Mission

By Gurbir Dated: November 18, 2014 Leave a Comment

Dr Mylswamy Annadurai is the program director for the Mars Orbiter Mission (MOM) launched in 2013 by the Indian Space Research Organisation. He served as the program director for the 2008  Chandrayaan-I mission to the Moon and is continuing that role for the Chandrayaan-2 currently in development.

ISROThis interview  was recorded in his office at   the ISRO’s Satellite Centre  in Bangalore on 26th March 2014 after MOM had been launched but before it had arrived at Mars.

India’s Mars Orbiter Mission

India launched its Mars Orbiter Mission (MOM) with its Polar Satellite Launch Vehicle (PSLV) launcher and everything, including the weather, performed as expected. The 1340KM Mars bound probe with a 15km  package of five science instruments will arrive at Mars in December next year.

Currently MOM is in Earth orbit where it will remain for another week.  Why? Because the Indian Space Research Organisation (ISRO) is still working on its more powerful launcher the Geosynchronous Launch Vehicle (GSLV) so had to use the less powerful but extremely reliable PSLV. Hence the modest science package and the requirement of six orbits of Earth for gravity assist.    Several engine firings  on  November 6, 7, 8, 9 and  11 are required, each one  increasing MOM’s speed. A final burn on 16th November will finally supply it the speed it needs to reach Mars. With another critical engine burn is required for arrival in Martian orbit on 1st of December. If that burn, almost a year from now fails, MOM will fly past Mars and be lost in space.

India’s space program was founded almost 50 years ago on the principle that space technology is an essential instrument for national development. Although commercial, military and scientific elements have since crept in, improving the quality of life for the huge Indian population, remains its primary objective.

ISRO has designated this as a technology demonstrator, India is building on the its Chandryaan-1 mission from 2008 but the engineering and technical challenges are an order of magnitude higher. ISRO was successful in reaching the Moon on its first attempt, it is hoping to do likewise with Mars.

Here is a 4 minute clip of my audio interview on Voice of Russia. I am introduced as a science journalist which of course I am not.

India and Space

By Gurbir Dated: October 28, 2013 Leave a Comment

November 21st 2013 marks 50 years of the Indian space program. From humble beginnings devoid of infrastructure, experience or trained engineers, India today has an established track record of designing, building and launching satellites for its own national needs and commercially for others.

The next few podcast offer a glimpse of the people and achievements of this half a century old story .. so far.

Episode 62: An interview with Amrita Shah from the Indian Institute of Science in Bangalore. Author of the most comprehensive biography on Vikram Sarabhai (Vikram Sarabhai :  A Life). Book review of this fascinating book here.

Episode 63: Rakesh Sharma – India’s only spaceman. A video interview recorded in August 2013 where Rakesh Sharma talks about his spaceflight, its aftermath and his views on human spaceflight. Two minute trailer below.

Episode 64 – Bangalore Astronomical Society. Probably the most productive amateur astronomical society in India with a huge presence online and thus an international footprint.

Episode 65 – Professor UR Rao. A look back at the contribution of former ISRO chairman who was originally recruited in to the Indian Space program by Vikram Sarabhai. Whilst working at NASA in the early 1960s, a cosmic ray scientist Rao worked on several Pioneer and Explore spacecraft. Rao was in Dallas waiting to meet Kennedy on that fateful day…

Episode 66 –  Interview with director at the Vikram Sarabhai Space Centre originally known as Thumba Equatorial Rocket Launch Station. TERLS was the site of India’s first rocket launch in to space on 21st November 1963.

Rakesh Sharma two minute trailer
