Episode 71: TATA Institute for Fundamental Research

By Gurbir Dated: May 25, 2015 Leave a Comment

 

Homi Bhabha 1909 - 1966
Homi Bhabha 1909 – 1966

The Indian Space Program was initiated by a brilliant nuclear physicist Homi Bhabha who pretty much immediately handed over the space program to Vikram Sarabhai. Bhabha himself pursued the goal of establishing premier scientific institutions for fundamental research in India. At the time he regarded scientific institutions to be critical for the new emerging independent India. Whilst working in the Indian Institute of Science, in 1945 he came up with the idea of an institution for fundamental research and went on to establish the Tata Institute for Fundamental Research (TIFR) which continues to operate today.

Although separate organisations, the connection between ISRO and TIFR remains strong to this day. Many of the instruments and subsystem onboard ISRO’s satellites are designed and constructed within TIFR. In this episode, the former director of TIFR, Professor Mustansir Barma talks about Homi Bhabha, his achievements in physics and the role of the TIFR in modern India.

Images and video from the partial Solar Eclipse 20 March 2015

By Gurbir Dated: May 7, 2015 Leave a Comment

Some images and short videos of the eclipse recorded from northwest England during a mostly cloudy morning of 20th March 2015. I used a video camera piggy-backed on my driven Vixen 102mm telescope along with a Cannon 550D at the prime focus for a few stills.  A mylar filter was used most of the time on both the scope and video camera but occasionally removed because the attenuation provided by the clouds was sufficient. Although mostly cloudy throughout the eclipse there were several intervals when the sun was not completely obscured and is when these recordings were made.

The video was shot using a Panasonic HDC HS900 camera and the first 4 still images are from that camera too. Click on any image to open gallery view.

 If you are intrigued by the birds in the images above. Here are the video clips from which they came at one tenth normal speed.

Episode 70: India’s Deep Space Network and ISRO Satellite Centre

By Gurbir Dated: April 30, 2015 Leave a Comment

Indian Deep Space Network India’s space program is now over half a century old. During this time its Infrastructure has evolved. This episode looks at the current communication capabilities used to support space vehicles during launch, in Earth orbit or on a interplanetary missions.

ISRO has an extensive network of ground stations on the Indian mainland, off-shore and neighbouring countries (Mauritius and Fiji) and collaborates with Norway, Russia, USA and European countries for mission specific needs. ISRO also has ship borne resources it deploys to meet individual mission profiles.

 

ISRODish1 copy‘s flagship deep space antenna is the 32m fully steerable dish at Byalalu close to Bangalore. It was established for the 2008 Moon mission and has been the primary resource for communicating with its Mars Orbiter Mission. Byalalu is also the central site for India’s Regional Navigation Satellite System IRNSS due to come in to full operation in 2016.

This conversation was recorded in March 2014 with the then director of the ISRO Satellite Centre SK Shivakumar who had been project leader that established the 32m antenna.

ISRO’s updated website – an overview

By Gurbir Dated: January 4, 2015 Leave a Comment

On 21st December 2014 ISRO updated its website (www.isro.org duplicated at www.isro.gov.in).  Even over the first few days after the update there have been additional minor updates so some of the screen dumps below may not precisely match what you may see.

Although there are still some shortcomings, the new clean, fresh user interface offers simpler navigation to information that has largely always been available but is now easier to get to. The new website is welcomed for another reason. Until the launch of ISRO’s Mars Orbiter Mission, ISRO did not really invest time and effort in its interface with the public. ISRO’s online presence is an international resource not just a national one. It is not useful only for the Indian nationals living abroad but the growing global community fascinated by space exploration and sees ISRO contribution as a critical endeavour for humanity’s future beyond Earth.

ISRO publishes much of what it does but could do more. Why the reluctance?  Could it be that ISRO feels a little overwhelmed by the established players with their substantial budget and impressive achievements? Material published after the demise of the USSR indicated it used its accomplishments in space to revive its global reputation. The launch of Sputnik in 1957 and then Gagarin six years later, changed how the USSR was perceived by the international community. ISRO is likewise helping India to step outside the shadow of a third world country. January 2014 started with a successful test of its indigenous cryogenic engine and ended with an equally successful crew module test launched atop its largest rocket GSLV3 in December. There was also a small matter of its Mars Orbiter Mission arriving at Mars in September to global acclaim. Although ISRO is finally beginning to recognise the strategic value of engaging with social media including Facebook, YouTube and Twitter, the engagement to date is at best – just a start.

Before highlighting some of the upsides of the updated website, I will start with an omission which oddly I found personally extremely  disappointing.

A mission statement in the header of the original website but missing from the new.

The vision expressed in the original homepage “The Indian Space Research Organisation Space Technology in the service of Human kind”. What it meant to ISRO or what it should mean to others was something ISRO never explained.  I was surprised by how sad I felt to see it missing. It did echo of something greater than just national ambitions and in using Humankind and not Mankind, ISRO hinted at a more pluralistic and egalitarian vision.  It is a key omission which I hope ISRO will reinstate in a future revision.

OK so what’s new. The 1990s style website which used multiple fonts of different sizes, colours and styles and the animated gifs has given way to a new uncluttered, slicker and clean home page. It is easier on the eye and consistent with modern web designs. Although potentially slow when using the mobile 3G network the new website has been optimised for mobile phone access.  The ISRO timeline (available via the About page or Footer) lists clickable hyperlinks to key ISRO  milestones from 1962 to the present works surprisingly well even on a mobile phone, although ISRO itself was formally established in 1969.

Both
The old and the new

Instead of cramming the home page with information, the new top-level menus point to specific areas like Missions, Spacecraft, Launchers, Applications, Media and About. The home page has many high quality images you only get to see if you scroll down. Excellent images but the home page is probably not the best place for them. First time visitors, especially those using mobile devices or low-bandwidth connection will experience a slow and disappointing response. For the first time, hi-res images and videos are now available under the Media menu. Announced almost a year ago ISRO’s dedicated YouTube channel has not yet made an appearance.

Shortening the length of the home page would also allow visitors easier access to the footer which really does contain some useful links (i.e. International Cooperation, Space Policy and ISRO’s Data Portal) that may otherwise be overlooked.    The redesign could also include a window to ISRO’s twitter feed.

Footer
Interesting and useful links in the footer but the overly lengthy home page renders the footer some what inaccessibl

One of the lesser known of ISRO’s sources is its Data Portal. By definition, as a portal it is not a data repository but a collection pointers to resources. Many of these sources have been available for a long time but have largely gone unknown and therefore unused. Although there is a need to increase the quantity and quality of the data available,  through this portal ISRO makes available the services for which ISRO was established directly to the public.

ISRO’s Data portal. I expect this is the one area that will grow in the quantity of data available in the coming years

The publications section has several brochures and documents for download in pdf format. Although it has some way to go, one of the more mature products from ISRO is known as Bhuvan.

Bhuvan is a multi-language Graphical Information Service available for and developed in India using indigenous datasets. Bhuvan, meaning Earth is a Google Maps like service launched in 2009. It provides high resolution 2D and 3D maps of many parts of India using satellite data collected over many years. The services available include

  • Disaster Services – which include realtime and historical information on Cyclone, Drought, earthquake, Flood, Fire and Landslide.
  • For Indian fisherman ISRO advisories known as Potential Fishing Zone (PFZ), recommends where they should go and fish.  These advisories are generated using Sea Surface Temperature and relative abundance of Chlorophyll derived from satellite imagery.
  • Ministry of the Environment and Forest – plot of lakes & rivers, land degradation and land use (since 2005-2011)

Bhuvan is an indian service designed for the benefit of the Indian population using using indigenous data and infrastructure. It is governed by the 2011 Remote Sensing Data Policy, so whilst that policy restricts public access to high resolution data for areas deemed to be in the interest of national security, the  same data is freely available to anyone via Google Earth.

This is the first overhaul the ISRO website has received in several years. Although there is much more  available than indicated in this short review, ISRO is not yet exploiting the full potential of social media.  In the global headlines that followed the success of the Mars Orbiter Mars, ISRO’s ability to bring costs down featured prominently. Sure, every rupee spent on publicity is a rupee  unavailable to its space program. But that is a false economy.

No one does outreach and publicity better than NASA but no one has a similar budget or the long-standing tradition. ISRO may not have the marketing skills or the experience but it does have the technical skills and the tech savvy people who can exploit social media.  ISRO needs a greater strategic commitment to policy, procedures and resources to showcase its achievements.    A greater use of its twitter account (say at least one tweet per day)  is one easy win that ISRO can implement right now without excessive cost or effort.

ISRO has notched up some truly remarkable achievements to date and has ambitious plans for the coming years. ISRO has a very poor track record of recording its activities that future historians (and ISRO itself) will lament. Of all the media – social media is probably the least expensive and most effective. Now that ISRO has recognised its value it should step up and engage with it fully.
