the Indian space program has come a long way since its inception in the 1960s. It all began with the establishment of the Indian National Committee for Space Research (INCOSPAR) in 1962, which was later reconstituted as the Indian Space Research Organisation (ISRO) in 1969. Since then, the program has achieved numerous technological milestones, including the launch of India's first satellite Aryabhata in 1975 and the successful insertion of the Mars Orbiter Mission (MOM) into Martian orbit in 2014. the Indian space program has also made significant contributions to the fields of remote sensing, satellite communication, and meteorology. This article provides a brief overview of the history of the Indian space program, highlighting its achievements and ongoing missions. We will delve into how the program has evolved over the years, the challenges that it has faced, and the future goals of the Indian space agency. By the end of this article, readers will have a good understanding of the Indian space program and its place in the global space industry.
The Early Development of the Indian Space Program: Aiming for the Stars
India’s space program began with humble beginnings in the 1960s. At that time, India was just starting to gain independence from British rule and was still considered a developing country. Despite this, India aimed to join the elite club of countries that had successfully launched satellites into orbit around Earth.
The Birth of ISRO
In 1962, the Indian National Committee for Space Research (INCOSPAR) was formed under Dr. Vikram Sarabhai's leadership, who is considered as father of Indian space program. It later became known as the Indian Space Research Organization (ISRO). The primary goal behind creating INCOSPAR was to develop indigenous capabilities in space technology and research.
First Rocket Launches
India’s first rocket launch occurred on November 21, 1963 when a Nike-Apache sounding rocket carrying sodium vapour payload was launched from Thumba Equatorial Rocket Launching Station (TERLS), located near Thiruvananthapuram in Kerala state. This marked India’s entry into space research.
The first satellite launch attempt by India took place on July 18th, 1980 when Rohini Satellite RS-1 was placed atop SLV-3 rocket but it failed during its flight itself due to an internal malfunctioning caused by a software bug.
SLV-3 Rocket Program
ISRO then embarked upon developing its own satellite launch vehicle named Satellite Launch Vehicle – III or SLV-3 which successfully launched Rohini Satellite RS-D1 on July 18th,1983 thus making India only seventh nation at that time which had capability to design and launch its own satellites.
The successful development of SLV-III paved way for further advancements in ISRO's capabilities including successful development and launches of Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV) which were used to launch several Indian and foreign satellites in orbit.
The Importance of Remote Sensing
Another significant achievement for ISRO during 1980s was its emphasis on remote sensing. In 1988, India launched its first remote sensing satellite, IRS-1A, which provided valuable data on natural resources and land use patterns. Today, India is a world leader in remote sensing technology with a fleet of satellites providing crucial data for various applications like agriculture, forestry management and disaster management.
Expansion and Competition: India’s Rise as a Space Power
The 1990s saw India’s space program expanding rapidly with increased funding, technology transfer from foreign players and successful launches of various satellites. This led to international recognition of ISRO's capabilities in space technology. In this section, we will explore the significant milestones achieved by ISRO during this period.
INSAT Series Satellites
ISRO launched a series of satellites under Indian National Satellite System (INSAT) which provided telecommunications, broadcasting and meteorological services to the country. INSAT-2B was launched in 1993 which further improved communication facilities across the nation.
PSLV Launches
The Polar Satellite Launch Vehicle (PSLV) saw numerous successful launches during this period including launching eight satellites simultaneously into orbit on May 26th, 1999. The PSLV also became an attractive choice for foreign satellite owners looking for low-cost launch options.
Moon Mission: Chandrayaan-1
ISRO's first mission to moon was Chandrayaan-1 which lifted off on October 22nd,2008 with aim to map lunar surface and detect water molecules thereon using its instruments like Terrain Mapping Camera(TMC), Hyper-spectral Imager(HySI), Lunar Laser Ranging Instrument(LLRI), among others. On November 14th,2008 it successfully placed Moon Impact Probe(MIP) containing Indian tricolor flag atop lunar surface becoming fourth nation ever after US,Russia & China to do so. It also discovered evidence of water molecules on moon's surface which caused global excitement among scientific community.
Mars Mission: Mangalyaan
India launched its Mars Orbiter Mission named Mangalyaan on Novemeber5th,2013 with aim to study Martian atmosphere , geology & search for methane gas signature indicating possible signs of life thereon using its instruments like Methane Sensor for Mars(MSM), Mars Exospheric Neutral Composition Analyser(MENCA), among others. On September 24th,2014 it successfully entered Martian orbit becoming first nation to do so in its first attempt and also achieved Guinness World Record for least expensive Mars mission ever undertaken.
Collaboration with Foreign Countries
ISRO also collaborated with foreign space agencies during this period like NASA, ESA (European Space Agency) and JAXA (Japanese Aerospace Exploration Agency) on various missions. India's successful launch of PSLV-C37 rocket which carried a record 104 satellites including 96 US satellites in February 2017 was widely appreciated by international space community.
Chandrayaan and Mangalyaan: India’s Trailblazing Missions to the Moon and Mars
India's Chandrayaan and Mangalyaan missions have been significant achievements of the Indian space program. In this section, we will explore these two missions in detail.
Chandrayaan-1
Chandrayaan-1 was India's first mission to the moon which was launched on October 22nd, 2008 by ISRO. The primary objective of this mission was to map the lunar surface, study its mineral composition and search for water molecules using a suite of scientific instruments.
Discoveries
-
Discovery of water molecules: One of the major discoveries made by this mission was that there was evidence of water molecules on the moon's surface. This discovery had global implications as it meant that future human missions could potentially extract water from lunar soil for drinking or as rocket fuel.
-
Mapping Lunar Surface: The spacecraft had five scientific payloads including Terrain Mapping Camera (TMC), Hyper-spectral Imager (HySI) an X-ray Spectrometer (C1XS) among others which took high resolution images & provided detailed maps showing topography and mineral composition across entire surface.
Mission End
The mission ended prematurely on August 29th, 2009 when all communication with spacecraft was lost due to technical failure resulting in loss of valuable information collected during its operation period.
Mangalyaan
Mangalyaan is India’s first interplanetary mission which aimed at studying Mars' atmosphere, geology & search for methane gas signature indicating possible signs of life thereon using a suite of scientific instruments. It lifted off from Sriharikota Space Center in Andhra Pradesh state on November5th,2013 aboard PSLV-C25 rocket.
Achievements
-
Entry into Martian orbit : On September 24th,2014 Mangalyan successfully entered Martian orbit becoming only fourth nation after US, Russia & China to reach red planet and also achieved the feat in its first attempt which was a major milestone for India's space program.
-
Discovery of Methane Gas : One of the major discoveries made by this mission was that there was trace amount of methane gas signature detected in Martian atmosphere. This discovery has significant implications as it could be a possible indication of past or present life on Mars.
Cost Effective Mission
One of the most notable features about Mangalyaan was that it became world's least expensive Mars mission ever undertaken costing only $74 million USD compared to NASA's Curiosity rover which costed over $2.5 billion USD.
Future Missions
ISRO is planning several future missions including Chandrayaan-3 and Aditya-L1 (to study Sun) among others with aim to further expand its knowledge about cosmos while developing indigenous technologies for space exploration.
