u/Ohsin · 11 pointsr/ISRO

There is good summary on page itself but some points still.

On PS4 Orbital platform

It'll have 100W of power and long duration orbital life.
Spin-stabilization is being rejected and a separate RCS module would be implemented as PS4's native RCS is not suitable for long duration operation.

On human spaceflight
Multiple air-drop tests planned to examine parachute performance. One is planned before 2019 end.
Multiple inflight abort tests (starting mid 2020) to verify crew escape system in various stages of flight.
December 2020 is being aimed for first Gaganyaan (uncrewed) flight.
Crew of four crew will be chosen (1 backup) selection process still underway (contradicting media reports).
No separate official term for Indian astronauts yet.

On SSLV
First 2 launches under ISRO later NSIL will undertake its operations. First launch 2019 end or start of next year.
Mobile launcher can be considered, sea launch not being considered due to large costs involved.
SSLV stages road transportable but currently will only launch from SHAR.
Not committing to new launch site at Kulasekarapattinam despite media reports suggesting otherwise.

On Venus orbiter mission (Shukrayaan).
Aiming at 2023 launch.
Payload development and design under progress.
Mass of spacecraft has been finalized (no number given)

Aditya-L1
In final stage of development and targeting second half of 2020 launch.

MOM-2
Still in early Mission Definition Phase!
No target dates yet. Even though in parliament they have said 2024.
Lander or surface probe is still being considered.

Chandrayaan-3
No announcement yet.

Chandrayaan-2
Fairly good idea on "Hard Landing".
Apparently nothing major was wrong and can fly again on same configuration.
Failure Analysis Committee report should be released soon.

On RLV LEX (Landing experiment)
Will perform Autonomous landing after being airdropped from helicopter at airstrip in Chitradurga, Challakere.
Aiming to execute by December 2019.

On Semi cryogenic (Kerolox) SCE-2000 engine.
Implementation of new stage with SCE-200 engine after 2022.
Would only implement new stage to GSLV Mk III after Gaganyaan project as it is being human rated.

Edit: /u/AstrotalkUK I think the book they mentioned is this one.
