• 2023 - Autonomous RLV Landing Experiment

  • The Reusable Launch Vehicle (RLV) named ==Pushpak== was designed for complex maneuvers and autonomous landings. An Indian Airforce Chinook helicopter lifted Pushpak to 4.5 km altitude and released it 4 km from the runway. Pushpak then autonomously flew to the runway, made necessary adjustments, and landed precisely using its brake parachute, landing gear brakes, and nose wheel steering.

PSLV-C57/Aditya-L1 Mission

Sep 2,2023:launch of Aditya-L1 by PSLV-C57

Jan 6, 2024 : Halo-Orbit Insertion (HOI)

Aditya L1 shall be the first space based Indian mission to study the Sun.

The spacecraft shall 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.

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.

Payloads made by Indian Institute of Astrophysics IIA - Bangalore and Inter University Centre for Astronomy and Astrophysics - IUCAA - Pune

Lagrange Points are positions in space where the gravitational forces of a two-body system like the Sun and Earth produce enhanced regions of attraction and repulsion. These can be used by spacecraft as “parking spots” in space to remain in a fixed position with minimal fuel consumption.

In-situ scientific experiments

Mission 3 :

Instrument for the Lunar Seismic Activity (ILSA) payload on Chandrayaan 3 Lander — the first Micro Electro Mechanical Systems (MEMS) technology-based instrument on the moon — has recorded the movements of Rover and other payloads.
Additionally, it has recorded an event, appearing to be a natural one, on August 26, 2023. The source of this event is under investigation.

ILSA payload is designed and realised LEOS, Bangalore. The deployment mechanism is developed by URSC, Bengaluru.

Laser-Induced Breakdown Spectroscope (LIBS) instrument onboard the Rover unambiguously confirms the presence of
Sulphur (S) in the lunar surface near the south pole, through first-ever in-situ measurements.

Al, Ca, Fe, Cr, Ti, Mn, Si, and O are also detected, as expected. Search for Hydrogen (H) is underway.
LIBS instrument is developed at the
Laboratory for Electro-Optics Systems (LEOS)/ISRO, Bengaluru.

Another instrument The Alpha Particle X-ray Spectroscope (APXS) has detected S.

Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere - Langmuir Probe (RAMBHA-LP) payload onboard Chandrayaan-3

The initial assessment indicates that the plasma near the lunar surface is relatively sparse.
These quantitative measurements potentially assist in mitigating the noise that Lunar plasma introduces into radio wave communication. Also, they could contribute to the enhanced designs for upcoming lunar visitors.

RAMBHA-LP payload development is led by SPL/VSSC, Thiruvananthapuram.

ISRO makes breakthrough demonstration of free-space Quantum Key Distribution (QKD) over 300 m

A number of key technologies were developed indigenously to accomplish this major feat, which included the use of indigenously developed NAVIC receiver for time synchronization between the transmitter and receiver modules, and gimbal mechanism systems instead of bulky large-aperture telescopes for optical alignment.

The demonstration has included live videoconferencing using quantum-key-encrypted signals. This is a major milestone achievement for unconditionally secured satellite data communication using quantum technologies.
