Obituary: UR Rao – pioneering satellite technologist and proponent of ‘ISRO Culture’

UR Rao

[vc_row][vc_column][vc_column_text]~By Dinesh C Sharma

The Indian Space Research Organistaion (ISRO) is today counted among the best space agencies globally. Much of the credit for this goes to UR Rao who helped the agency master technology for making complex communication, weather and remote sensing satellites with limited resources and difficult circumstances such as technology denial.

Having started his career as a doctoral student of Vikram Sarabhai in 1954 at Physical Research Laboratory (PRL) in Ahmedabad, Udupi Ramachandra Rao spent his scientific career spanning almost half a century for developing and nurturing the Indian space programme. After a brief stint in America as a postdoc at Massachusetts Institute of Technology (MIT) and Jet Propulsion Laboratory (JPL), Rao returned to India at the behest of Sarabhai.

Throughout the 1960s, Sarabhai was feverishly trying to put together a plan for developing space technology applications in India after having successfully set up the sounding rocket facility at Thumba in Kerala. He asked Rao, who had worked on spacecraft systems while being at NASA, to prepare a blueprint for development of space technology in India. Then he asked Rao to implement the plan. The rest of Rao’s life was spent in doing so, beginning with the fabrication of India’s first satellite – Aryabhata – launched in April 1975.

Aryabhata, weighing 358 kg, was built from scratch by a young team of engineers and scientists put together by Rao at a newly created facility in the Peenya industrial estate in Bangalore. The facility later became the ISRO Satellite Centre with Rao as its founding director. The Soviets launched Aryabhata from the Kapustin Yar Cosmodrome, without charging any fee, purely as a friendly gesture. This was followed by launch of Bhaskara 1 and 2, and Rohini series of satellites.

If Aryabhata got a free launch from the Soviet Union, the first experimental communication satellite – Ariane Passenger Payload Experiment (APPLE) – was launched for free on a development flight of Ariane vehicle of European Space Agency (ESA) from Kourou in 1981.

The American media ridiculed India’s foray into space when it was ridden with other problems as poverty. News weekly, Newsweek, carried a picture of APPLE being transported from the hanger to test center in a bullock cart with a caption ‘Collision of Centuries’. Many years later, Rao explained in an interview why the satellite was carried on a bullock cart: “We had to ship the satellite for EMC (Electromagnetic Interference/Capability) testing, and trucks made of metals were throwing off reflections that were affecting the satellite’s antenna. Then somebody hit on the idea of a bullock cart, which is made of wood. It worked perfectly.” 

With the experience gained from building experimental satellites in the 1970s, Rao came up with an ambitious idea of building larger communication, remote sensing and multi-purpose satellites with practical applications. Thus were born the legendary series of Indian satellites in the 1980s – the INSAT (Indian National Satellite) and IRS (India Remote Sensing Satellite) – which provided communication, broadcasting, weather and earth observation services to a variety of Indian users. Thus within two decades, Rao could demonstrate the applicability of space technology for national development, as envisioned by his mentor Sarabhai. This is despite the problems Rao was facing in the 1980s with successive failures of Augmented Satellite Launch Vehicle (ASLV).

In all, over 20 satellites were designed and launched under his guidance. Besides laying the foundation for self-reliance in satellite building, Rao is credited with building a new way of executing complex technology project – which many call the ‘ISRO Culture’. All space projects are complex, challenging, multi-disciplinary, time-critical, and – in the case of India – have to be executed with limited budget. Rao mastered this art. Leveraging his experience of working with NASA, Rao introduced a matrix management structure for managing projects by ensuring optimal use of available resources. The ISRO culture encompasses decentralized decision making for technology development, systems engineering, quality assurance, peer review and thorough failure assessment. Actually this is what differentiates ISRO from other scientific agencies in India.   

Rao came from a humble background. He was born in Udupi in Karnataka. “I saw a train for the first time when I had to go to Bellary for Intermediate. I had never seen a train because no trains used to come to Udupi. They used to come to Mangalore, which is about 58 km from Udupi. Udupi was a taluka at that time, but there were four rivers, at each river you had to take a boat to cross and then take another one. It was a big effort going to Bangalore from Udupi,” Rao had recalled in an interview a few years ago.

He first thought of space technology while doing M. Sc. at Banaras Hindu University. “I said I wanted to be a space scientist. I was not sure my own professor would have welcomed it because at that time space was not a hot subject, but I had a dream. The main thing is we must dream and then you have to just dedicate yourself for that.” (India Science Wire)[/vc_column_text][/vc_column][/vc_row]

MK Stalin predicts frequent PM Modi visits to Tamil Nadu before assembly election

MK Stalin has said Prime Minister Narendra Modi will visit Tamil Nadu more often ahead of the Assembly election, calling the tours politically motivated and questioning the Centre’s support to the state.

MK Stalin

Tamil Nadu Chief Minister M. K. Stalin has predicted that Prime Minister Narendra Modi will increase his visits to the state as the Assembly election, expected in April or May, draws closer.

Speaking ahead of the polls, the DMK president said the Prime Minister has already begun touring Tamil Nadu and is likely to visit frequently in the coming months. He claimed that such visits could create discomfort within the BJP-led National Democratic Alliance (NDA), as alliance partners may fear the political impact of repeated appearances.

Stalin calls visit politically motivated

The Chief Minister described the Prime Minister’s scheduled programmes in the state as “politically motivated”. PM Modi is set to attend various events in Madurai in southern Tamil Nadu, including the inauguration of the first phase of the AIIMS hospital project. He is also expected to visit the Thiruparankundram Temple amid the Karthigai Deepam-related controversy and participate in a public meeting organised by the NDA.

Stalin said he has been working for all sections of the population, including those who did not vote for his party. In contrast, he remarked that some leaders are visible in the state only during election time and increase their visits as polls approach.

Criticism over Union Budget allocations

The DMK leader also criticised the BJP-led central government, accusing it of neglecting Tamil Nadu. He pointed out that while approval was recently granted for the Gujarat Metro project, there were no major announcements or allocations for Tamil Nadu in the Union Budget.

Stalin asserted that voters would remember the lack of significant measures for the state. He framed the upcoming election as a contest between Tamil Nadu and the NDA, stating that the state should be governed from Fort St George in Chennai rather than from Delhi.

The ruling DMK is currently allied with several smaller parties and, at present, the Congress, as it seeks a third consecutive term in office. Its principal rival, the AIADMK, is aligned with the BJP as part of the NDA.

Shashi Tharoor questions Centre over Kerala name change to Keralam

Shashi Tharoor has criticised the Centre’s decision to approve renaming Kerala as Keralam, questioning its impact and pointing to the lack of major projects for the state.

Congress MP Shashi Tharoor has criticised the central government over its decision to approve the renaming of Kerala as ‘Keralam’, arguing that the move prioritises symbolism over development.

Reacting to the Union Cabinet’s approval, Tharoor said that the state’s name has always been ‘Keralam’ in Malayalam and questioned the practical impact of introducing the Malayalam term into English usage.

“It has already been ‘Keralam’ in Malayalam. So now, a Malayalam word is coming into English. I don’t know what difference it makes,” he said, adding that the state has not received major projects such as an AIIMS or new institutions from the Centre. He also pointed out that no significant allocations were made for Kerala in the Union Budget.

In a separate post on X, Tharoor raised what he described as a “small linguistic question” about what residents of the state would be called if the name change is implemented. Referring to existing terms such as “Keralite” and “Keralan”, he remarked that alternatives like “Keralamite” sounded like a microbe and “Keralamian” like a rare earth mineral.

The Union Cabinet, chaired by Prime Minister Narendra Modi, cleared the proposal on Tuesday. The move comes ahead of the upcoming state Assembly elections, in which 140 members of the legislative assembly are to be elected. The poll schedule is yet to be announced by the Election Commission of India.

The state assembly had earlier passed a resolution seeking the change in official records. Chief Minister Pinarayi Vijayan had moved the resolution in 2024, urging the Union government to adopt the name ‘Keralam’ in all languages listed in the Eighth Schedule of the Constitution.

He had stated that the demand for a united Kerala for Malayalam-speaking people dates back to the national freedom movement.

Tamil Nadu potboiler: Now, Sasikala to launch new party ahead of election

Sasikala has announced the launch of a new political party ahead of the Tamil Nadu Assembly elections, positioning herself against AIADMK chief Edappadi K Palaniswami.

Published

In a significant political development ahead of the Tamil Nadu Assembly elections, expelled AIADMK leader V. K. Sasikala has announced that she will float a new political party and contest the polls by fielding her own candidates.

Speaking in Madurai before heading to Pasumpon for a public event, Sasikala said she would unveil her party’s flag later in the evening. She indicated that more details regarding the party’s structure and plans would be shared at the gathering.

The event venue carries political symbolism. Pasumpon is the birthplace of Thevar leader Muthuramalinga Thevar, and Sasikala herself belongs to the influential Thevar community in southern Tamil Nadu. The programme was held as part of birth anniversary events of former Chief Minister J. Jayalalithaa.

Direct challenge to EPS

Sasikala’s move is being viewed as a direct political challenge to AIADMK general secretary Edappadi K. Palaniswami (EPS). After Jayalalithaa’s death in 2016, Sasikala briefly took control of the party and had appointed Palaniswami as Chief Minister. However, following her conviction in the disproportionate assets case, she served a four-year prison term, and during that period, she was expelled from the party.

Palaniswami later aligned with O. Panneerselvam, whom Sasikala had earlier removed from the Chief Minister’s post. The two leaders subsequently adopted a dual leadership arrangement within the party and government.

Sasikala remains disqualified from contesting elections until 2027 due to her conviction. Nevertheless, she has stated that she intends to field candidates under her new party banner.

Fragmented Thevar vote base

Over the years, expulsions within the AIADMK — including Sasikala, her nephew TTV Dhinakaran and O Panneerselvam — have led to divisions within the Thevar support base. Political observers have linked this fragmentation to the party’s weakened electoral performance in the elections following Jayalalithaa’s passing.

While Dhinakaran has returned to the NDA fold, reports suggest Palaniswami is opposed to any arrangement that includes Sasikala or Panneerselvam. OPS, meanwhile, has exited the NDA.

Sasikala has repeatedly criticised Palaniswami, describing him as a betrayer, while he maintains that his leadership stems from the support of AIADMK legislators rather than her backing.

The AIADMK has not issued an official statement on Sasikala’s announcement. However, a senior party leader questioned her political standing, pointing out her disqualification from contesting elections and referring to legal issues linked to Jayalalithaa’s death.

With the Assembly polls approaching, Sasikala’s re-entry into active politics could further complicate the opposition space in Tamil Nadu and influence electoral calculations, particularly in the southern districts.
