ISRO demonstrated the Reusable Launch Vehicle Autonomous Landing Mission (RLV LEX) on 2nd April, 2023 at the Aeronautical Test Range (ATR), Chitradurga, Karnataka. The autonomous landing was carried out under the exact conditions of a Space Re-entry vehicle’s landing “high speed, unmanned, precise landing from the same return path” as if the vehicle arrives from space. Landing parameters such as Ground relative velocity, the sink rate of Landing Gears, and precise body rates, as might be experienced by an orbital re-entry space vehicle in its return path, were achieved. The RLV LEX demanded several state-of-the-art technologies including accurate Navigation hardware and software, Pseudolite system, Ka-band Radar Altimeter, NavIC receiver, indigenous Landing Gear, Aerofoil honey-comb fins and brake parachute system
PSLV-C55/TeLEOS-2 mission

Both belong to Singapore. They were launched into an Eastward low inclination orbit
GSLV-F12/NVS-01 Mission
The mission was successfully accomplished on 29th May, 2023. GSLV deployed the NVS-01 navigation satellite. NVS-01 is the first of the second-generation satellites envisaged for the Navigation with Indian Constellation (NavIC) services. NVS series of satellites will sustain and augment the NavIC with enhanced features. This series incorporates L1 band signals additionally to widen the services. For the first time, an indigenous atomic clock will be flown in NVS-01.
Gaganyaan Service Module Hot tests
ISRO successfully tested the Gaganyaan Service Module Propulsion System (SMPS) on July 19, 2023 at ISRO Propulsion Complex (IPRC) , Mahendragiri. This test involved five liquid apogee motor (LAM) engines with a thrust of 440 N and sixteen reaction control system (RCS) Thrusters with a thrust of 100 N. The Service Module of Gaganyaan is a regulated bi-propellant based propulsion system that caters to the requirements of the Orbital Module, performing orbit injection, circularization, on-orbit control, de-boost manoeuvring and SM based abort (if any) during the ascent phase. The 440 N Thrust LAM engines provide the main propulsive force during the mission ascending phase, while the RCS thrusters ensure precise attitude correction. ISRO successfully carried out two more hot tests on the Gaganyaan Service Module Propulsion System (SMPS) at ISRO Propulsion Complex (IPRC), Mahendragiri on July 26, 2023.
Crew Module Recovery trials
On February 7, 2023, ISRO, along with Indian Navy carried out initial recovery trials of Crew Module in the Water Survival Test Facility (WSTF) of the Indian Navy, at Kochi. The trials were part of the preparation for crew module recovery operations for the Gaganyaan mission that will be carried out in Indian. As the safe recovery of the crew is the final step to be accomplished for any successful human spaceflight, it is of paramount importance and it has to be carried out with the minimum lapse of time. Hence the recovery procedures for various scenarios need to be extensively practiced by carrying out a large number of trials.
PSLV-C56/DS-SAR Mission
The mission was successfully accomplished on 30th July, 2023. The DS-SAR satellite is developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering. Once deployed and operational, it will be used to support the satellite imagery requirements of various agencies within the Government of Singapore.
Aditya-L1 Mission
On September 02, 2023, Aditya-L1 spacecraft – India’s first solar observatory as launched on board PSLV C57. Aditya L1 is the first space based Indian mission to study the Sun. The spacecraft will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This will provide a greater advantage of observing the solar activities and its effect on space weather in real time. The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors. Using the special vantage point L1, four payloads will directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium The spacecraft underwent a 
series of manoeuvers and is currently on its way to the Sun-Earth Lagrange Point 1(L1), having escaped the Earth’s 
Sphere of Influence.
Gaganyaan Test Vehicle-D1 launch
The first developmental flight of Test Vehicle (TV-D1) was successfully accomplished with the in-flight abort demonstration of the Crew Escape System (CES) on October 21, 2023 from FLP, SDSC, Sriharikota. In-flight Abort Demonstration of Crew Escape System (CES) at Mach number 1.2 with the newly developed Test Vehicle followed by Crew Module separation & safe recovery was successfully demonstrated. TV-D1 Crew Module was safely recovered from sea with the help of Indian Navy and transported back to ISITE, Bengaluru.
