Google commemorates 100th birth anniversary of Vikram Sarabhai

Widely regarded as the father of India’s Space programme, today marks the birth centenary of Vikram Sarabhai. India and ISRO will be marking this day with events in Ahmedabad and Bangalore. Google marked the day with a doodle.

A few interesting facts I came across during my research for the book The Indian Space Programme:

  • 1930 – He accompanied Gandhi on his Salt March to Dandi
  • 1935 – Got a letter of introduction to Uni of Cambridge from Rabindranath Tagore
  • 1942 – Married Mrinalini Swaminathan during a very low key ceremony at her home in Bangalore.
  • 1947 – Completed his PhD viva in Manchester England under scrutiny Nobel laureate Professor Patrick Blackett
  • 1950s Praful Bhavsar and UR Rao completed their PhD under Sarabhai
  • 1961 – Wrote to the Government of India proposing a space satellite programme for India
  • 1966 – When Bhabha suddenly, Sarabiz took over as Chairman of the DAE and secretary at the AEC, his first goal was to steer India away from Bhabha’s vision of an India with a nuclear bomb
  • 1969 – He signed the MoU with NASA Administrator to initiate the SITE programme which brought satellite TV in 1975 to rural villages in India

Chapter 7 in my book is on Vikram Sarabhai. The best-researched book about his life and work is – Vikram Sarabhai: A life by Amrita Shah.

Buzz Aldrin in Yorkshire

To commemorate the 50th anniversary of Apollo 11- reposting this 10-minute interview with Buzz Aldrin recorded on 30 April 2008. This was originally posted as episode 12. Some of the topics we spoke about were

  • Only became an astronaut after he failed to acquire a Rhodes scholarship.. twice!
  • Saw the Aurora borealis (Northern lights) from New Jersey
  • Saw more stars from Texas or Hawaii than when is space. The visor protection prevented him from seeing anything in the night sky except the Earth and the Sun from the lunar surface.
  • Dedicated his PhD thesis to the “the crew members of this country’s present and future manned space programs”.
  • Was concerned that his illness from Hepatitis may have impacted his NASA selection.
  • In 2002 he whacked a guy (persistent conspiracy theorists) at the “spur of the moment”.
  • Agrees that the film “In the shadow of the Moon” portrayed an accurate representation of the manned mission to the Moon

Chandrayaan-2 – Back to the Moon

Pragyan Touchdown. – Scheduled for 01:55 IST on 7 September 2019

[ycd_countdown id=5360]

T+
Successful Launch on 14:43 IST on Monday 22 July 2019

Second Attempt: Monday 22 July 10:13 BST (14:43 IST)
First Attempt: Sunday 14 July – 22:21 BST. ** Launch aborted at T- 56M 24s**

Reason for abort: The third stage of the GSLV Mk3 uses a cryogenic engine where liquid Hydrogen and liquid Oxygen are the propellents. Loading these propellents (first Oxygen and then Hydrogen) is completed just minutes prior to lift off.  A Helium container above the Oxygen tank began to leak at a particular pressure. It was the detection of this leak at T-56 minutes that the mission was aborted. ISRO engineers have confirmed that they can make the fix at the launch pad without the need to return the launch vehicle to the Vehicle Assembly Building.

Reschedule: The new launch date is 22nd July 2019 at 10:13 BST. Chandrayaan-2 was going to take 54 days to get to the Moon, the delayed departure will be compensated for during the Earthbound manoeuvres. It will now take 47 days to get to the Moon. The original landing date of 6th September will not change.

If all goes to plan (weather is looking a little dodgy) Chandrayaan-2, India’s second moon mission will lift off from India’s Space Port – Sriharikota at 22:21 BST. This will be India’s second Moon mission since Chandrayaan-1 launched in 2008. 

This mission consists of an orbiter, lander and a rover. It will be launched on a GSLV Mk3, India’s “heavy lift” launcher. To date, the GSLV-Mk3 has had 3 successful flights (one of which was suborbital). Click on any image to open gallery view.

David Baker has been involved with the USA since childhood. First attending a US school in England and then studying in the US under a scholarship program sponsored by Senator Clinton P Anderson. He returned to the USA and worked for NASA on various programs from Gemini to the SpaceShuttle. After leaving NASA, he set up one of the earliest private space sector companies in London.

(Note – following questions on the veracity of his Phd, David Baker resigned from the BIS as the editor of Spaceflight on 25th March 2021.)

Today he is the editor of the British Interplanetary Society’s monthly journal – Spaceflight and a prolific author of space books. Some of the topics we spoke about include

  • Early interest in space and astronomy stimulated by milestones such as breaking of the sound barrier, Sputnik and Gagarin’s flight.
    Completed his PhD in Earth and Planetary physics.
  • Worked for Nasa between 1965 and 1984. Mainly in the mission
    Setup a consultancy in 1984 to bring US launch and satellites services to the wider international community.
  • Setup a consultancy in 1984 to bring US launch and satellites services to the wider international community
  • Delayed the launch of STS-41B in February 1984 carrying payloads for Indonesia and Western Union but problems with the payload Assist Modules did not meet the insurance certification requirements.
  • Was involved in the purchase by India its 4 INSAT satellites (INSAT 1A-1D) from Ford Aerospace in the USA.
  • Published over 110 books and more in the pipeline to mark the 50th anniversary of Apollo 11.
