Thumba is a suburb of Thiruvananthapuram city, capital of Kerala, India.


History

Till 1963, the obscure village of Thumba would not have merited a second look. A quintessential Kerala fishing hamlet with thatched huts, coconut groves and peaceful sea, it was an unlikely setting for a rocket launch station. However, it did have something that caught the interest of Dr Vikram Sarabhai, the father of India’s space programme. A small church dedicated to St Mary Magdalene that was located on the Earth’s magnetic equator.

The magnetic equator is an imaginary line around the planet that connects all the points where a magnetic needle, when freely suspended, is horizontal. It is scientifically important because the magnetic equator is all where the Equatorial Electrojet exists – a stream of electrons whizzing across the sky, about 110-120 km above the Earth’s surface.

Sounding rockets, or the first rockets sent out by any space programme, test and study these electrons for research in the fields of physics, astronomy, and meteorology. These rockets are the baby steps taken before the establishment of a full-fledged space programme and Dr Sarabhai felt that Thumba was the best place to launch them. In fact, Thumba’s location at 8°32’34” N and 76°51’32” E is ideal for low-altitude, upper atmosphere and ionosphere studies.

So, one fine day, Dr Sarabhai and his fellow scientists (including Dr APJ Abdul Kalam) went to Thumba to talk to the then-bishop of Trivandrum who lived in the house adjacent to the church. They were interested in acquiring the church and the nearby land for their first rocket launch. Instead of giving them a definite answer, Reverend Peter Bernard Pereira asked them to attend the Sunday mass that week, where he would put the question to the parishioners.

At the mass, the bishop explained the scientific mission and asked the permission of his congregation to hand over the church to the scientists. In his book Ignited Minds: Unleashing the Power Within India, Dr. A.P.J. Abdul Kalam has described this particular incident beautifully.

Thanks to the Reverend’s efforts, permission was granted, the paperwork was done and the villagers relocated to a new village with a brand new church in 100 days flat. The bishop’s home was quickly converted into an office, the church became the workshop, and cattle sheds served as storage houses and laboratories. Undeterred by the little funding and few facilities, a handful of enthusiastic young Indian scientists began assembling their first rocket.

Carefully selected by Dr Sarabhai, the then-chairman of the national committee on space research, these young scientists and engineers had been trained in sounding rocket assembly and launching at NASA’s Wallops Island launching facility in Virginia, United States. The early recruits included former President APJ Abdul Kalam, and veteran scientist R Aravamudan.

In the initial stages, Thumba had no canteen or facilities of any sort, so the scientists would cycle every day to the railway station at Trivandrum for their breakfast and dinner (they would get their lunch packed). In those days, the only jeep was always busy, so the scientists had to either walk or use a cycle to move within the range. While weekdays would be very busy, the scientist would have nothing much to do during holidays or weekends. So, they would either go to the beaches at Kovalam or Shankumukham or catch an old Hollywood movie at Srikumar theatre.

Back then, even rocket parts and payloads were transported by bullock carts and bicycle to the launch pad. It was in these unassuming settings that India staged its first launch—that of a Nike-Apache rocket supplied by NASA. This is how it happened.

After six months of labour, on 21 November 1963, India was ready for its very first rocket launch. Many eminent names in science and technology had gathered for the occasion, including Dr Homi J. Bhabha (the father of Indian nuclear programme) and Dr P R Pirashoty (the founder-director of Indian Institute of Tropical Meteorology). The Governor of Kerala was also there along with the district collector and the bishop.

When the rocket was rolled out on to the launch pad, the sultry air was thick with tension. And almost immediately the things started going awry. As the rocket was being hoisted onto the launcher, the hydraulic crane developed a leak. Somehow, it was manually shifted into position. Next, remote system of the launcher malfunctioned. Once this was fixed, things finally seemed in order. As the alarm sounded to clear the area around the launch pad, the team of scientists held their breath.

At 6.25 pm, the world was watching as the rocket streaked away into the gathering dusk. Minutes later, a sodium vapour cloud had emerged in the sky high above, tinted orange by the setting sun. India had successfully put its first signature on space.

An elated Dr. Sarabhai sent a telegram home saying: “Gee whiz wonderful rocket show.” Dr Kalam later remembered how the very next day, Dr Sarabhai had congratulated the happy team and spoken to them about his dream of an Indian satellite launch vehicle. And over the years, Indian Space Research Organisation (ISRO) has not only fulfilled the visionary leader’s dream, but has also made India’s space programme the envy of the world with its ‘success on a shoestring’.

Fifty three years later, Thumba is the hub of all space programmes helmed by the Indian Space Research Organisation (ISRO). The Vikram Sarabhai Space Centre at Thumba has given India launch vehicles, geo-stationary satellites (used for telecommunications, television transmission and weather forecasting) and some of the finest remote sensing satellites.

As for the little church that helped India reach for the stars, it now houses a space museum replete with a fascinating array of rockets, satellites and other astronomical equipment.

Location and geography

Thumba is a vast village bordering Meenumkulam in the east, St. Dominic's Vettucaud in the north, and Kochuthura in the south; towards its west is the Arabian Sea. While the border with Meenumkulam is the Parvathi Puthannaar canal, the border with Kochuthura is the Rajiv Gandhi Nagar road. The entire village is flat at sea-level and the ground near to the coast is made of tan coloured beach sand. This is in stark contrast to the rest of the village where the ground is made of white sand where, till the developments of the late 1990s, large amounts of a medicinal herb with white flowers called Thumba grew in abundance, hence the name. TERLS dedicated to the United Nations on February 2, 1968.

Overview

First rocket launched from Thumba Equatorial Rocket Launching Station in 1963

Thumba became well-known to the out-siders after the establishment of Thumba Equatorial Rocket Launching Station (TERLS), which was the first of that kind in India. TERLS was founded in Thumba in 1962 in the district of Trivandrum on the southern tip of India very close to earth's magnetic equator to launch sounding rockets. Thumba also happened to be one of the farthest points from Pakistan and China.

Dr. H G S Murthy, D Eswar Das, M R Kurup and A. P. J. Abdul Kalam were amongst the initial team of rocket engineers.[1]

Rocket launches

First rocket launch:

The first sounding rocket, Nike-Apache, was launched rocket on 21 Nov 1963. The Rohini Sounding Rocket (RSR) program to develop indigenously developed and fabricated sounding rockets launched the first single-stage Rohini (RH-75) rocket (32 kg rocket with 7 kg payload to ~10 km altitude) in 1967, followed by a two-stage Rohini rocket (100 kg payload to over 320 km altitude).[2]

Other launches:

Apart from Indian payload, sounding rockets from many other countries (including United States, Russia, Japan, France, Germany) were also launched from Thumba, as part of mutual international collaboration. TERLS developed infrastructure for all aspects of rocketry, ranging from rocket design, rocket propellant, rocket motor casting, integration, payload-assembly, testing, evaluation besides building subsystems like payload housing and jettisonable nose cone. Fibre-reinforced plastic composite materials for nose cone were used in early programs at TERLS.

The rocket launch from TERLS came to a stand-still in 2000. Later in 2002, the rocket launchings were resumed from TERLS.[3] ISRO announced their plans to launch 180 number of RH-200 rockets from TERLS over the next five years.
