Guys, unfortunately there won't be unmanned Gaganyaan this year

1st mission will be in early 2023
2nd Mission will be in late 2023
manned mission will be some time in 2024, most likely late 2024.

Personally ,I don't even believe this time line, manned flight may be slipped to early or mid 2026 in my opinion

EXCLUSIVE: No Gaganyaan unmanned flight this year - The Week

^ Is ISRO itself stating this? Not good, after building up hopes. At least the GSLV Mark 3 for Chandrayaan-3 is ready. They should accelerate that program. As well as the conventional civilian launches.

I feel conflicted about the constant shifting of the timeline.

From 2021 to 2022 to 2023 and now 2024 which i am 90% sure will shift further to 2025-26.

Anyways
better late than never,safety should always be a priority.

let everything to go safe. Why so hulla over 2-3 years of delay? you guys are making it like it will be delayed by decades.
You all know the situation of the country since last 1-2 yrs, delays were expected.

Chandrayaan-3 planned later this year now. Gaganyaan, probably coz of being a more complex mission (or the haste for LPEM), has been dropped for two years.

Department of Space demonstrates entanglement based quantum communication over 300m free space along with real time cryptographic applications

On 27 January 2022, scientists from the two premier laboratories of Department of Space (DOS), viz. Space Applications Centre (SAC) and Physical Research Laboratory (PRL), both from the city of Ahmedabad, have jointly demonstrated quantum entanglement based real time Quantum Key Distribution (QKD) over 300m atmospheric channel along with quantum-secure text, image transmission and quantum-assisted two-way video calling. The demonstration was conducted at SAC, Ahmedabad, between two buildings separated by a distance of 300 m. This experiment and demonstration were repeated over several nights to ensure the repeatability and robustness of indigenously developed QKD system capable of seamlessly generating and utilizing secure keys for various applications.

Shri. S. Somanath, Chairman, ISRO / Secretary, DOS has witnessed this live breakthrough demonstration at SAC, Ahmedabad. Shri. Nilesh M Desai, Director SAC and Dr. Anil Bhardwaj, Director PRL were also present during the demonstration. Various images were encrypted using generated quantum key and transmitted over classical channel from one building to another building separated by 300m and decrypted at the receiving terminal in real time.

This is yet another significant step towards the development of the planned Satellite Based Quantum Communication (SBQC). This feat comes after the earlier breakthrough demonstration of quantum secure videoconferencing by SAC-ISRO using ‘prepare-and-measure’ quantum communication technology, in free space, over a distance of 300 m on 19 March 2021.

In order to achieve this technology feat, scientists developed various key technologies like robust & high brightness entangled photon source (EPS), BBM92 protocol implementation, NavIC enabled synchronization, polarization compensation technique etc. A cryptographic application software suite with integrated quantum security has also been developed and demonstrated for text, image, video encryption/decryption.

The BBM92 protocol based quantum communication link was demonstrated in the experiment. The secure-key-rate achieved was ~1.8 kbps, with Quantum Bit Error Rate (QBER) of less than 10%. Quantum entanglement was achieved with Bell’s parameter and quantum visibility greater than 2.2 and 80% respectively.

With these developments, ISRO, Department of Space is getting ready for satellite based demonstrations of fundamental quantum mechanics experiments as well as quantum communication for future-proof data security.

Good news, though overdue. If they have solved the technical issue, then( excuse the layman's reasoning) why not launch this first, since it is the most easy to assemble? Probably something to do with prioritising the PSLV/Risat-1A and Oceansat-3.

Last year during ground test, the rocket motor of SSLV didn't perform well.
