MY'STORY

The MOVE Fire

This is a personal recollection on the Move fire on May 13, 1985 Philadelphia police fired thousands of rounds at the MOVE house, city officials approved dropping an explosive device on the roof, the resulting fire was allowed to burn, 11 people—including five children—died, and 61 homes were destroyed. Philadelphia City Council later called it a “brutal attack carried out by the City of Philadelphia on its own citizens” and acknowledged that no individual faced criminal consequences for the bombing. One timeline correction worth preserving for the BHP record: the major previous MOVE-police confrontation was August 8, 1978, about seven years before the bombing, not a year or two earlier. Officer James Ramp was killed, other police and firefighters were wounded, nine MOVE members were later convicted, and television cameras recorded police beating Delbert Africa during his arrest. The 1985 MOVE Commission later specifically criticized city planners for failing to adequately use lessons from that 1978 confrontation. And that actually strengthens the point you’re making: 1985 did not happen without precedent or institutional memory. There had already been a deadly confrontation with MOVE, years of conflict, negotiations and police involvement before Osage Avenue.

The Liquid Propulsion Systems Centre (LPSC) is a research and development centre functioning under ISRO.[2] It has two units located at Valiamala, in Thiruvananthapuram, Kerala, and Bengaluru, Karnataka. LPSC is augmented by ISRO Propulsion Complex at Mahendragiri of Tamil Nadu.

LPSC is engaged in development of liquid and cryogenic propulsion stages for launch vehicles and auxiliary propulsion systems for both launch vehicles and satellites. Activities related to liquid propulsion stages, cryogenic propulsion stages and control systems for launch vehicles and spacecraft is done at Thiruvananthapuram. Precision fabrication facilities, development of transducers and integration of satellite propulsion systems are carried out at Bangalore. The developmental and flight tests along with assembly and integration are done at ISRO Propulsion Complex, Mahendragiri in Tamil Nadu.

The development of liquid propellant stages for the PSLV, control systems for SLV-3, ASLV, PSLV and GSLV, satellite propulsion systems including those for INSAT and IRS and production of pressure transducers are done by the LPSC for India. The LPSC has developed indigenous cryogenic upper stage for Geosynchronous Satellite Launch Vehicle (GSLV) which was successfully test fired by ISRO on 4 August 2007. LPSC is currently developing a restartable LOX-Methane engine and stages for the Next Generation Launch Vehicle, which uses a reusable booster stage.[3]

LPSC's current director is Mr. Jayan N.[4]

Formerly, IPRC was known as LPSC, Mahendragiri, functioning under LPSC. It was elevated as an independent centre and renamed as IPRC with effect from 1 February 2014. The complex is situated near Panagudi in Tirunelveli District, Tamil Nadu. It is one of the ISRO centres that could be called as the "Jet Propulsion Laboratory of India" as all liquid, cryogenic and semicryogenic stage and engine related tests of ISRO's launch vehicles and satellites are carried out here.

Thiruvananthapuram

Thiruvananthapuram (Malayalam pronunciation: [t̪iɾuʋənən̪d̪ɐˈbuɾəm] tirr-ROO-və-nun-Tə-poor-əm), also known as Trivandrum, is the capital city of the Indian state of Kerala. As of 2011, the Thiruvananthapuram Municipal Corporation had a population of 957,730 over an area of 214.86 km2, making it the most populous city in Kerala. The larger Thiruvananthapuram metropolitan area has over 1.7 million inhabitants within an area of 543 km2, making it the second-most populous metropolitan area in Kerala after Kochi.. Thiruvananthapuram is one of the few cities in India that serves as a state capital and is also centre for heritage, maritime activities, information technology, research and development, space research, defence, automotive technology, and biosciences. It is also among the few cities in the world where both an international airport and an international seaport are located within the city in close proximity to the city centre. Located on the west coast of India near the extreme south of the mainland, Thiruvananthapuram is a port city located 10 nautical miles (19 km; 12 mi) from a heavily trafficked east–west shipping channel. The city is home to India's first deep-water trans-shipment port, owned by the Vizhinjam International Seaport Ltd. Thiruvananthapuram under the Government of Kerala. The city is characterised by its undulating terrain of low coastal hills. Thiruvananthapuram is also known for its cultural heritage, being associated with the musical contributions of Swathi Thirunal Rama Varma and the artistic legacy of painter Raja Ravi Varma. Thiruvananthapuram has contributed to the development of Malayalam literature through individuals like Ulloor S. Parameswara Iyer, Kumaran Asan, C. V. Raman Pillai and Narayana Guru. The city is also known for Sree Padmanabhaswamy Temple, known as the richest temple in the world. The other temples includes the Sreevaraham temple, the Shreekanteswaram temple and the Attukal Bhagavathy temple. The present regions that constitute Thiruvananthapuram were ruled by the Ays who were related to feudatories of the Chera dynasty. In the 12th century, it was conquered by the Kingdom of Venad. In the 18th century, the king Marthanda Varma expanded the territory, founded the princely state of Travancore and made Thiruvananthapuram its capital. Travancore became the most dominant state in Kerala by defeating the powerful Zamorin of Calicut in the battle of Purakkad in 1755. Following India's independence in 1947, Thiruvananthapuram became the capital of Travancore–Cochin state and remained so until the new Indian state of Kerala was formed in 1956. Thiruvananthapuram is a notable academic and research hub and home to the University of Kerala, APJ Abdul Kalam Technological University, the regional headquarters of Indira Gandhi National Open University, and many other schools and colleges. Thiruvananthapuram is also home to research centres such as the National Institute for Interdisciplinary Science and Technology, the Indian Space Research Organisation's Vikram Sarabhai Space Centre, the Indian Institute of Space Science and Technology, the National Centre for Earth Science Studies and a campus of the Indian Institutes of Science Education and Research. Thiruvananthapuram is where India's space programme began, with the headquarters of Liquid Propulsion Systems Centre located there. The city is home to media institutions like Toonz Animation India and Tata Elxsi Ltd, and also to Chitranjali Film Studio, one of the first film studios in Malayalam Cinema, and Kinfra Film and Video Park at Kazhakoottam, which is India's first infotainment industrial park. In 2012, Thiruvananthapuram was named the best Kerala city to live in, by a field survey conducted by The Times of India. In 2013, the city was ranked the fifteenth best city to live in in India, in a survey conducted by India Today. Thiruvananthapuram was ranked the best Indian city for two consecutive years, 2015 and 2016, according to the Annual Survey of India's City-Systems (ASICS) conducted by the Janaagraha Centre for Citizenship and Democracy. The city was also selected as the best governed city in India in a survey conducted by Janaagraha Centre for citizenship and democracy in 2017.

Vikas (rocket engine)

The Vikas engine (a portmanteau from initials of VIKram Ambalal Sarabhai ) is a family of hypergolic liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre in the 1970s. The design was based on the licensed version of the Viking engine with the chemical pressurisation system. The early production Vikas engines used some imported French components which were later replaced by domestically produced equivalents. It is used in the Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV) and LVM3 for space launch use. Vikas engine is used to power the second stage of PSLV, boosters and second stage of GSLV Mark I and II and also the core stage of LVM3. The propellant loading for Vikas engine in PSLV, GSLV Mark I and II is 40 tons, while in LVM3 is 55 tons.
