The 12 months 2023 has been a busy one for the Indian Space Research Organisation (ISRO) with the house company already efficiently finishing 4 missions efficiently up to now 5 months. While it is a milestone in itself, the house calendar for India will proceed to stay packed for the approaching months, as a number of the largest house missions—together with the much-awaited Chandrayaan-3, India’s third lunar mission, Aditya-L1, the solar mission, and the uncrewed and crewed missions of Gaganyaan—are additionally progressing at a promising tempo, scientists assured.
Senior scientists from the division of house mentioned that after the success of the Small Satellite Launch Vehicle (SSLV) D2 or SSLV-D2/EOS-07 mission that was accomplished in February, the second batch of 36 OneWeb satellites in March, the Polar Satellite Launch Vehicle (PSLV-C55) mission carrying two Singapore satellites, TeLEOS-2 and Lumelite-4, and the launch of India’s first second technology navigation satellite tv for pc, NavIC or NAVigation with the Indian Constellation, ISRO is now gearing up for India’s third lunar mission, Chandrayaan-3. This will possible be adopted by Aditya-L1.
“2023 and 2024 are very exciting years for Indian space missions. We have some heavy-duty missions planned for the year ahead and we are very excited about it. The immediate missions that we are working towards are Chandrayaan-3 and Aditya-L1, India’s moon and sun missions,” a senior ministry official confirmed.
Here’s a more in-depth take a look at what ISRO’s calendar seems like for the remainder of the 12 months and the subsequent.
Chandrayaan-3
ISRO chairman S Somnath confirmed that the launch window for Chandrayaan-3 will open on July 12 this 12 months. All the assessments across the mission have been accomplished and the launch automobile has arrived at ISRO’s Satish Dhawan Space Centre (SDSC) in Sriharikota in preparation for the July launch.
The Chandrayaan programme, also referred to as the Indian lunar exploration programme, is an ongoing collection of outer house missions by ISRO. The first moon rocket, Chandrayaan-1, was launched in 2008, and was efficiently inserted into lunar orbit.
Chandrayaan-2 was efficiently launched and inserted into the lunar orbit in 2019, however its lander “crash-landed” on the moon’s floor when it deviated from its trajectory whereas trying to land on September 6, 2019, as a result of a “software glitch”, in response to ISRO’s mission doc.
In May, the house company began the meeting course of for the payloads for Chandrayaan-3, a transfer to make sure that the house company is ready to stick with the launch date of July, senior officers from the division of house mentioned. The meeting occurred on the UR Rao Satellite Centre (URSC) in Bengaluru, earlier than it was despatched to the Sriharikota house port for the launch.
Chandrayaan-3 consists of an indigenous lander module, a propulsion module and a rover. Its aims embody creating and demonstrating new applied sciences required for interplanetary missions. The lander could have the aptitude to mushy land at a specified lunar website and deploy the rover, which is able to perform in-situ chemical evaluation of the lunar floor.
The major perform of the propulsion module is to hold the lander module from launch automobile injection until the ultimate lunar 100km round polar orbit and separate the lander module from the propulsion module. Apart from this, the propulsion module additionally has one scientific payload as a worth addition, which shall be operated post-separation of the lander module.
Chandrayaan-3 shall be launched by Launch Vehicle Mark-3 (LVM3) rocket from Satish Dhawan Space Centre, Sriharikota. The propulsion module will carry the lander and rover configuration until the 100 km lunar orbit.
Aditya-L1
Aditya-L1, however, is India’s first devoted scientific mission to review the solar. Earlier, this mission was conceived as Aditya-1 with a 400kg class satellite tv for pc carrying one payload, the VELC, and was deliberate to be launched in an 800km low earth orbit.
However, since a satellite tv for pc positioned within the halo orbit across the first Lagrangian Point (L1) of the sun-earth system has the most important benefit of repeatedly viewing the solar with none occultation/eclipses, the Aditya-1 mission was renamed as Aditya-L1 mission, which shall be inserted in a halo orbit across the L1—1.5 million km from the earth in direction of the solar.
This will present a better benefit of observing the photo voltaic actions and its impact on house climate in actual time. The spacecraft will carry seven payloads to look at the photosphere, chromosphere and the outermost layers of the solar—the corona—utilizing electromagnetic and particle and magnetic subject detectors.
Scientists defined that utilizing the particular vantage level L1, 4 payloads instantly view the solar, and the remaining three payloads perform in-situ research of particles and fields on the Lagrange level L1, thus offering essential scientific research of the propagatory impact of photo voltaic dynamics within the interplanetary medium. The main goal of this mission is to review the photo voltaic higher atmospheric (chromosphere and corona) dynamics, chromospheric and coronal heating, physics of the partially ionised plasma, initiation of th/e coronal mass ejections, and flares.
ISRO officers mentioned that after the Chandrayaan-3 mission, the subsequent big-ticket mission for the house company shall be Aditya-L1, which is more likely to be scheduled for August this 12 months.
Gaganyaan (uncrewed and crewed missions)
ISRO’s Gaganyaan mission envisages demonstration of human spaceflight functionality by launching a crew of three members to an orbit of 400km for a three-day mission and bringing them again safely to earth, by touchdown in Indian sea waters. However, earlier than India sends its chosen astronauts to house, there shall be a collection of uncrewed assessments—at the moment scheduled for early 2024—to make sure that the techniques are secure for human journey.
“The mission is achieved by an optimum technique by contemplating inhouse experience, expertise of Indian business, mental capabilities of Indian academia and analysis establishments together with leading edge applied sciences obtainable with worldwide businesses,” ISRO said in its mission document.
“The prerequisites for Gaganyaan mission include development of many critical technologies including human rated launch vehicle for carrying crew safely to space, life support system to provide an earth like environment to crew in space, crew emergency escape provision and evolving crew management aspects for training, recovery and rehabilitation of crew,” the document stated.

Last month, the Indian Navy along with ISRO released a recovery training plan for India’s first human space flight mission at the Water Survival Training Facility at INS Garuda, Kochi. The space agency is hoping to complete its test vehicle missions and pad abort tests—two key tests for the mission—this year before the unmanned flights are conducted in the first quarter of 2024. The manned mission is expected to happen in the second half of next year, officials said.
NISAR
NASA-ISRO Synthetic Aperture Radar or NISAR as it is being called, is another mission to look forward to in 2024. This is the first time that National Aeronautics and Space Administration (NASA), the US civil space programme, and ISRO are collaborating on an Earth-observing mission. NASA’s Jet Propulsion Laboratory (JPL) is leading the US part of the project and is providing the mission’s L-band SAR (synthetic aperture radar) and the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. ISRO is partnering to provide the spacecraft bus, the S-band SAR, the launch vehicle, and associated launch services and satellite mission operations.
“Once in operation, NISAR will be able to collect measurements day and night, in all weather conditions, and its trove of data will help researchers better understand a broad range of Earth science topics, including landslides, groundwater loss, and the carbon cycle,” JPL said in a statement issued in February.
The US leg of the mission has been completed and the payloads were officially handed over to Isro early this year. After a few rounds of tests, the mission will be ready for launch “early next year”, ISRO scientists mentioned.
