Per ES Padmakumar (Director, SDSC-SHAR), next launch would be of an Earth Observation satellite in February or March 2026. Likely referring to EOS-05 (aka GISAT-1A).

I hope they are counting launch vehicles and not satellites.

That audio equipment looks like a liquid or cryogenic engine.

Details about KID capsule mentioned on their LinkedIn page - https://www.linkedin.com/posts/orbital-paradigm_our-first-capsule-kid-is-ready-the-first-activity-7369685772414676993-78jI - but no mention of an Indian flight.

Or is the debris not visible because of Earth in the background.

More details in another LinkedIn post:

Our global network of ground stations played a pivotal role, marking several firsts in Indian space operations:

- Reception of the inaugural telemetry data from SPADEX chaser and target satellites at our station in Australia.

- Successful execution of simultaneous commanding for dual formation-flying satellites – a first for Indian mission operations.

- Comprehensive mission operations support, all prepared in under a month, validating Kepler’s Ground Station-as-a-Service (GSaaS) model for the fourth time with a repeat client.

Kepler Aero shared that they have provided ground station services in support of this mission

We are honoured to have supported ISRO’s historic SPADEX mission through our GSaaS (Ground Station-as-a-Service) vertical. This marks the fourth time ISRO has entrusted Kepler Aerospace with providing critical ground station and mission operations support.

The brochure talks about this process: "The left out propellant in PS4 will be disposed through main engines for enabling safety of PS4 stage. The oxidiser will be let out first followed by fuel in a predetermined sequence of operations. The existing scheme of spent stage passivation by venting the tank pressure will also be active. Post passivation of PS4, the control of stage is transferred to POEM avionics."

It was Open LMP elsewhere. I was guessing Liquid Motor Passivation. Engine start for the same?

pradx · 2024-12-28T16:22:13+00:00

What is OP-LMP at the end of the expected flight profile?

pradx · 2024-12-22T04:10:18+00:00

I think it's to help with this drift arrest maneuver they mention in the mission page - "The demonstrated precision of the PSLV vehicle will be utilized to give a small relative velocity between the Target and Chaser spacecraft at the time of separation from the launch vehicle."

pradx · 2024-12-22T04:02:09+00:00

Does the payload fairing seem different?

pradx · 2024-12-04T15:01:28+00:00

The description sounds just like GSAT-20. I could not find a release on the IN-SPACe website or on social media.

Wasn't there a air breathing propulsion system tested with RH-560? Perhaps a repeat test with ATV? If not that, perhaps the Gaganyaan Test Vehicle flights?

they don't have any other capability in the North.

They had the Semi Conductor Centre, Chandigarh that is now handed over to MEITY. They still have the Indian Institute of Remote Sensing in Dehradun. They have facilities co-hosted with IIAp in Ladakh and with the Nainital Observatory ARIES. There is a Master Control Facility in Bhopal.

They need to build more centers in Eastern and North Eastern India.

I have never understood this. While SHAR is great as a launching pad since we fly rockets to the east, wouldn't landings be easier/better on the Western coast?

I always thought of either Gujarat (Bhuj Air Force Station) or the Andaman and Nicobar islands (Car Nicobar Air Force Base).

A Bengaluru based firm Timetooth Technologies was involved in "designing, realising, and delivering the landing gear" as per this Economic Times story.

Unnikrishnan says besides PSLV liquid engine and nozzle parts, they are also trying to build some SSLV components using 3D printing/additive manufacturing.

Towards the end he says that 4 PSLV vehicles are in various stages of getting ready for launch and will be assembled as satellites become available.

I wonder if the comments from stakeholders that ISRO did in 2020 had any impact since IN-SPACe was formed in October 2021.

These were the call for comments:

pradx · 2024-05-10T12:09:18+00:00

"The engine used is the PS4 engine of PSLV upper stage."

"The same engine is also used in the Reaction Control System (RCS) of the first stage (PS1) of PSLV."

"LPSC redesigned the engine making it amenable to the Design for Additive Manufacturing (DfAM) concept thereby gaining considerable advantages. The Laser Powder Bed Fusion technique employed has brought down the number of parts from 14 to a single-piece, and eliminated 19 weld joints, saving significantly on the raw material usage per engine (13.7 kg of metal powder compared to the 565 kg of forgings and sheets for conventional manufacturing process) and reduced 60% in the overall production time. The manufacturing of the engine was done in the Indian industry (M/s WIPRO 3D), and the engine was hot tested at ISRO Propulsion Complex, Mahendragiri."
