ISRO Achievements of 2022: The year 2022 was an important one for the Indian Space Research Organisation (ISRO) because the space agency conducted its first mission of the Small Satellite Launch Vehicle, completed the first commercial mission of India’s heaviest launch vehicle, and achieved important milestones for the Gaganyaan Programme, among other accomplishments. This year, India’s first high throughput satellite broadband service was launched with ISRO infrastructure. 

ISRO launched India’s first virtual space museum in August. The Indian space agency also launched India’s first privately developed rocket, Vikram-S. Recently, ISRO shared the first images of Earth captured by Earth Observation Satellite OceanSat-3 from space. 

Here are some of the most important feats achieved by ISRO this year. 

December 2022

Hypersonic vehicle trials: On December 9, 2022, ISRO and Headquarters, Integrated Defence Staff, jointly conducted hypersonic vehicle trials. “The trials achieved all required parameters and demonstrated hypersonic vehicle capacity,” ISRO said in a mission update. 

A hypersonic vehicle flies faster than five times the speed of sound, or Mach 5, and can enable a new class of flight vehicles that enable faster access to space, rapid military response at long range, and faster means of commercial air travel, according to an article published in the book, Lightweight Composite Structures in Transport. An aeroplane, missile or spacecraft can serve as a hypersonic vehicle. Rocket boosters can be used to develop a hypersonic vehicle. 

Since a hypersonic engine uses oxygen from the atmosphere, the need to carry oxygen aboard the aircraft is eliminated. This reduces significant vehicle weight. 

In order to produce a particular amount of thrust, the engine requires less than one-seventh the propellant that rockets need. 

In September 2020, India became the fourth country to research and test defence weapons, after China, Russia and the United States.

India has tested a Hypersonic Technology Demonstrator Vehicle (HSTDV) missile that travelled six times faster than the speed of sound. 

Australia, France, Germany and Japan are developing hypersonic weapon technology, and Iran, Israel and South Korea are conducting “foundational research” on hypersonic weapons, according to an article published by Voice of America. 

MoU with Vyom Space: On December 6, 2022, ISRO and the Indian National Space Promotion and Authorisation Centre (INSPACe), an autonomous agency under the Department of Space, Government of India, signed a Memorandum of Understanding (MoU) with a private firm Vyom Space Exploration and Services. The MoU was signed to develop niche technology in the field of space, with special focus on a human and cargo transportation capsule programme.

The images were captured using the Ocean Colour Monitor (OCM) and Sea Surface Temperature Monitor (SSTM) sensors. 

PSLV-C54 Mission: On November 26, 2022, ISRO launched OceanSat-3A along with eight nano-satellites, as part of the PSLV-C54 or EOS-06 mission. OceanSat-3A is also called EOS-06. The other payloads launched were BhutanSat, a Bhutanese satellite, a nano-satellite called Anand, developed by Pixel India, and other nano-satellites developed by Dhruva Space, Astrocast and Spaceflight USA, a Seattle-based aerospace company.

The satellites were launched atop a Polar Satellite Launch Vehicle (PSLV), from First Launch Pad, Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh. 

OceanSat-3A is an Indian satellite designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on OceanSat-2, and will facilitate the potential of applications in other areas, according to The main objectives of the satellite are to study surface winds and ocean surface strata, monitor phytoplankton blooms, study suspended sediments and aerosols in the water, and observe chlorophyll concentrations.

OceanSat-3A, the third flight unit of the OceanSat programme, has a mass of 960 kilograms, operates at 1,360 Watts, and has been placed into a sun-synchronous orbit. 

India’s first private launchpad in ISRO campus: On November 25, 2022, Indian space-tech firm Agnikul Cosmos launched the country’s first private launchpad and mission control centre inside the ISRO campus at Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh. Agnikul Cosmos, a private aerospace manufacturer, has designed the launchpad, and will operate it.

The establishment of India’s first private launchpad marks a significant step in opening the Indian space sector to private players, ISRO says on its website. The facility inside the ISRO campus has a launchpad and mission control centre, the latter being four kilometres away from the launchpad.

Gaganyaan Parachute Test: On November 18, 2022, ISRO successfully completed the Integrated Main Parachute Airdrop Test (IMAT) of Gaganyaan’s crew module deceleration system, marking a significant milestone for the Gaganyaan Programme. The Vikram Sarabhai Space Centre, where many Gaganyaan activities are being carried out, conducted this major development test at the Babina Field Fire Range (BFFR) in Jhansi district, Uttar Pradesh.

The Gaganyaan Programme aims to demonstrate indigenous capability to undertake human spaceflight missions to low-Earth orbit.

The Parachute system for the Gaganyaan crew module consists of 10 parachutes. During the descent of Gaganyaan astronauts towards Earth in the future, two apex cover separation parachutes will be deployed in the initial stage. These parachutes serve as protection covers for the crew module parachute deployment. After this, two drogue parachutes will be deployed to stabilise the descent and bring down the velocity of the astronauts. 

After the release of drogue parachutes, three pilot chutes will be used to extract three main parachutes individually, ISRO says on its website. This will help reduce the speed of the Gaganyaan crew module to safe levels before landing. Of the three main parachutes, two are sufficient to land the astronauts on Earth. The third parachute is redundant. 

Complex testing methods such as rail track rocket sled (RTRS) will test the performance of the smaller parachutes, and aircraft or helicopters will evaluate the performance of the main parachutes. A rocket sled is a test platform that slides along a set of rails, propelled by rockets, and provides a controlled environment for high-velocity impact, aerodynamic and acceleration tests for articles such as payloads, aircraft and missiles, among others. 

The Integrated Main Parachute Airdrop Test is important because it simulated a scenario in which one main parachute failed to open. This parachute test is the first in a series of tests planned to simulate different failure conditions of the Gaganyaan Parachute system. The system will be deemed qualified to be used in the first human spaceflight mission if all the tests are successful.

In order to conduct the airdrop test, a five-tonne dummy mass, equivalent to the crew module mass, was taken to an altitude of 2.5 kilometres, and dropped using the Indian Air Force’s (IAF’s) IL-76 aircraft. 

According to ISRO, the fully inflated main parachutes reduced the payload speed to a safe landing speed during the test, which lasted about two to three minutes. The airdrop test was successful, as the payload mass landed softly on the ground.

ISRO and the Defence Research and Development Organisation (DRDO) have designed and developed the parachute-based deceleration system for the Gaganyaan crew module. 

Despite the fact that one of the main parachutes was prevented from opening in this simulated test, the inflated main parachutes successfully landed the payload on the ground. In this way, the first in a series of development tests planned to evaluate the performance of the Gaganyaan parachute system was successful.

Launch of India’s first privately-developed rocket: On November 18, 2022, ISRO launched India’s first privately developed launch vehicle, Vikram-S, as part of the Prarambh mission. Prarambh was the maiden mission of Hyderabad-based space-tech startup Skyroot Aerospace, and received support from ISRO as well as INSPACe.

Vikram-S was successfully launched into space from Sriharikota. The rocket carried three customer payloads, manufactured by Space Kidz India, Bazoom Q Armenia and N-Space Tech India.

Vikram-S was developed in a record time of two years, and was powered by solid fuels. It has cutting-edge avionics and all-carbon fibre core structures. 

Vikram-S has a mass of 345 kilograms, a length of six metres, a diameter of 0.375 metres, a peak vacuum thrust of seven tonnes, can carry payloads weighing up to 83 kilograms to a maximum altitude of 100 kilometres, and has solid rocket boosters that have been 3D-printed to ensure spin stability. 

The successful launch of Prarambh makes Skyroot Aerospace the first private space company in India to launch a rocket into space, marking the beginning of a new era for the Indian space sector, which was opened up for commercialisation in 2020.

Antriksh Jigyasa: In November this year, ISRO launched a virtual platform called ‘Antriksh Jigyasa’, meaning ‘Space Curiosity”. This is a knowledge portal for exploring space science, technology, engineering and mathematics (STEM) and active learning. Antriksh Jigyasa offers self-paced online courses on space science, technology and their applications.

The launch vehicle is a catalyst for the Indian Space Programme, because it will ensure the launch of heavy payloads into low-Earth orbit.

September 2022

Hybrid motor test: The Vikram Sarabhai Space Centre successfully test-fired a hybrid motor at the ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu, on September 20, 2022.

The test-fire was supported by the Liquid Propulsion Systems Centre (LPSC), a research and development centre functioning under ISRO. A hybrid motor, unlike solid-solid or liquid-liquid combinations, uses solid fuel and liquid oxidizer. The 30 kilonewton hybrid motor tested by ISRO used Hydroxyl-terminated polybutadiene (HTPB) as the solid fuel, and liquid oxygen as the oxidizer, which are compounds readily reacting with most organic material without any energy input.

SSLV-D1 Mission: On August 7, 2022, ISRO launched the maiden flight of its smallest launch vehicle. The Small Satellite Launch Vehicle (SSLV) took flight from First Launch Pad, Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The mission, called SSLV-D1, was the first developmental flight of the launch vehicle. 

The primary payload of SSLV was an Earth Observation Satellite called Microsat 2A or EOS-02. A satellite named AzaadiSAT was also launched into space as a co-passenger on SSLV.

However, SSLV failed to place Microsat 2A and AzaadiSAT into the intended circular orbit. As a result, the satellites are no longer usable, ISRO said in a mission update. 

SSLV-D1 was supposed to place the two satellites into a 356-kilometre circular orbit. However, the satellites were instead placed into a 356 km × 76 km elliptical orbit. 

ISRO said that the space agency will soon launch SSLV-D2, the second flight of SSLV.
