Episode 90 – An update on ISRO’s activities with S Somanath and R Umamaheshwaran

By 10 Comments

R Umamaheshwaran (Scientific Secretary) and S Somanath (Director of the Vikram Sarabhai Space Centre)

This interview with S Somanath (director of the Vikram Sarabhai Space Centre) and R Umamaheshwaran (Scientific Secretary) was recorded on 24th October 2019 during the International Astronautical Congress in Washington DC. It was not focused on a specific theme but rather an update on all things ISRO – current and future activities. We spoke about ISRO’s potential participation with NASA on its Artemis programme, ISRO’s innovative Orbital Platform (repurposing the 4th stage of a PSLV), Human Spaceflight and Gaganyaan, Small Satellite Launch Vehicle, Semi Cryogenic engine development, potential new launch site Kulasekharapattan, Chandrayaan-2 and future international collaboration.

The award-winning book mentioned is Integrated Design for Space Transportation System by B.N Suresh and K. Suresh.

The conversation started with India’s bid to be the host for IAC2022. The other candidates were Brazil, Singapore and Azerbaijan. The day after this recording it was announced that the International Astronautical Federation selected Azerbaijan.

Some of the topics we covered are listed below

  • India, along with Singapore, Azerbaijan and Brazil were candidate countries to host 2022 IAC. India hosted the IAC 1988 and 2007. This interview was recorded a day before the announcement was made. Baku, the capital of Azerbaijan was selected as the host for 2022.
  • Potential ISRO participation with NASA’s Artemis programme return to the Moon. Italy and Japan will join NASA. (ISRO remains uncommitted at this stage).
  • PS4 Orbital Platform – ISRO is making use of the 4th stage of the PSLV to host payload in LEO for several months after it has completed the delivery of the primary payload(s). It will be augmented with RCS and propulsion system to maintain attitude and orbit – potentially indefinitely! Solar panel on the outside will deliver up to 100W. End of mission, the platform will comply with agreed guidelines – to a minimum perigee of 500km if not deorbit.
  • Gaganyaan – Coming up parachute tests by end of this year, launch abort t(in-flight) test. Uncrewed test flight next year and 2021. Crewed flight to LEO by 2022 is still on target.
  • Crew selection process is still progressing. Selection criteria require test pilot experience so females will not be part of the first crew. The first flight will consist of a crew of 3. Initially, a team of 4 will go to Russia for astronaut training – a single backup. (Surprising – I would have expected at least 6 for two teams – primary and back up).
  • Human Spaceflight and Exploration conference in Bangalore, India in January 2020. This mission is to generate public awareness of India’s Gaganyaan programme. Rakesh Sharma and astronauts from other countries will also be present.
  • Small Satellite Launch vehicle (SSLV) to address the newly developing market for small satellites. Currently, small satellites use rideshare that does not offer customised timing or orbit. Both are determined by the primary payload. The SSLV to only from Sriharikota.
  • The reference in the Indian (Google translation from original Telegu) press for a proposed new launch site in Kulasekharapattan is not really taken seriously by ISRO. Initially to be launched from Sriharikota but may develop a mobile launcher in the future. Sea launch is not under consideration at the present.
  • Alternative launch sites may come in the future but currently, Sriharikota’s launch capacity is not being used fully.
  • ISRO’s first mission to Venus (Shukriyaan) to be launched in 20203. Mass and mission architecture already defined. Aditya-L1 – launch in the second half of 2022. Mars Orbiter Mission 2, architecture not yet finalised – may include lander and rover. No date yet.
  • Chandrayan-3 – not announced yet but there will be a Chandrayaan-3 and more.
  • Failure Analysis Committee investigating. ISRO has a fairly good idea from the data on what went wrong. So far – hard landing resulting in spacecraft damage. Why did it happen? The problem is a minor due to “dispersion”? i.e. something was off-nominal but would not say if hardware or software issue? The FAC report will be publically published.
  • Space station – announced by the ISRO chairman. It will happen but no timeline.
  • Reusable Launch Vehicle second mission will involve an airdrop and land on a strip at Chitradurga in Karnataka. Target date – December 2019.
  • Semi cryogenic engine. Engine development in progress with a target date of 2022. Testing and significant progress will take place AFTER the Gaganyaan mission is over.
  • Next GSLV-Mk3 scheduled for mid-2020 for comsat launches.
  • Will India use the name “astronaut”? ISRO will conduct something in the way of a public poll and make a formal decision.
  • Gaganyaan will not be one-off. May go to the Moon, ISS or participate in Artemis. ISRO not ruling out anything.
  • ISRO continuing to cooperate with Russia, France, ESA, the USA, Collaboration with China is also possible. Two experiments from the Indian Institute of Science will be conducted on the Chinese Space Station. Collaboration with China in science is straight forward but at the agency level – that may come in the future

Episode 84: NASA after the Shuttle. SLS and The Gateway

David Baker

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. He was present in mission control in 1970 and witnessed the drama of Apollo 13 first hand.

He joined the British Interplanetary Society in 1965, published his first article in the society’s journal Spaceflight in 1969 and since 2011 has been the editor of that very journal -Spaceflight. To date, he has published a remarkable 110 books by the close of 2018 with a few more in the pipeline for 2019 to mark the fiftieth anniversary of Apollo 11.

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

In this episode, we talk about the current status of the space programme in the US and the changing role of NASA.

  • The USA has not been able to launch US astronauts from the USA since the retirement of the Space Shuttle in 2011. NASA found itself in a similar position between 1975 (Apollo Soyuz Test programme) and the first Space Shuttle in 1981.
  • Why NASA dropped the Ares programme and why its replacement, the Space Launch System (SLS) schedule remains unclear. The first SLS mission, uncrewed – Exploration Mission-1 (EM-1) by 2020 and the second crewed mission, Exploration Mission-2 (EM-2) by 2023.
  • The successor to the ISS, the “Gateway” is an international project for a space station in lunar orbit. Only about a third of the size of the ISS and it will have fewer international partners.
  • The gateway is seen by Russia as an American lead programme. Will Russia participate with the gateway or consider a joint Russia/China human spaceflight programme?
  • China/USA cooperation in space has been prohibited ny US law. What prospects that this will change?

Heads of Space Agency Press Conference IAC2018

This is my recording of the Heads of Space Agency press conference, 1st October – the first day of IAC2018. This video was not initially intended to be published. But here it is unedited – some may find it of interest.

In Attendance:Left to right

  • Dmitry Loskutov in place of Dmitry Rogozin – (Roscosmos)
  • Hiroshi Yamakawa – (JAXA)
  • Johann-Dietrich Woerner – (ESA)
  • Maggie Aderin-Pocock (Moderator – BBC)
  • Jim Bridenstine – (NASA)
  • K. Sivan – (ISRO)
  • Sylvain Laporte – Canadian Space Agency (not present)
  • Zhang Kejian, China National Space Administration (not present)

Some notes

Head of Roscosmos Dmitry Rogozin – prevented by sanctions against Russia to travel to Germany. Replaced by Dmitry Loskutov.

Bridenstein:

  • Experiments on ISS from 103 countries
  • Gateway – Open architecture, a fraction of the size of the ISS is not in LEO so has no radiation protection from the Van Allen Belts
  • Reduced electromagnetic radiation from Earth. May allow new experiments in astrophysics
  • Multiple trips to the lunar surface from the Gateway and hence potential for new science experiments on the surface.
  • Question: Is NASA subsidising SpaceX?  Did not deny it outright at the outset.
  • NASA’s goal is to establish a capability, reduce costs, and enhance innovation. Ultimately, more customers for SpaceX, not just NASA, and more service providers – not just SpaceX.
  • My question is: when will the US law prohibiting US/China collaboration in space end? 
  • Answer: The law expires and is renewed every year. (Left it open ended really). 
  • Question: Is China’s space programme too close to the Chinese military? Answer: This is a concern for US government, and NASA will do what its government permits it to do 

Sivan

  • India has no plans for human missions to the Moon.
  • Regarding India cooperating with China on human spaceflight training, he left it open-ended. I think he was aware of the deal that the Modi administration was making with Russia (announced a few days later), but could not say anything at this press conference.

Woerner:

  • ESA Astronauts are learning Chinese. Will fly with China in the future but no date yet.
