Problem is budget. No budget no expansion in human resource, so pressure will automatically come.

Aiyyooo SSLV successfully test fired!!! I hope they released videos i am so hard rn!!!!! AAAAAAAAAAAAAh!!Sorry I read the ISRO website, but it says that the launch is expected in May
Ground testing of Solid Booster Stage (SS1) for Small Satellite Launch Vehicle (SSLV) - ISRO
The ground testing of the newly developed solid booster stage (SS1) for the new launch vehicle of ISRO i.e. Small Satellite Launch Vehicle (SSLV) was carried out today, March 14 2022 at Satish Dhawan Space Centre Sriharikota at 1205 hrs. All the propulsion parameters during the test are found...www.isro.gov.in
I like your date of March 25-31 a lot more. Is this still possible?

New interview of Dr. Pawan Goenka chairman of INSPAC with Pallala Baagla.
Few months back i saw him visiting private space startups like Agnikul and Skyroot and I kinda liked it that he was actively promoting private players. His new video further provides some insights,
-> Space plan is ready
-> INSPAC will act as a promoter as well as a regulator for space related activities (will try to streamline the regulations process into a single window clearance)
-> He actively stresses on the need of Private-public partnership, ISRO handholding and using the strength of startups.
-> One of the good things that i liked was his focus on 'creating demand' and not being stagnant with practical goals more we will know later but i like the start.
-> Some interesting info about private players and promoting space related activities among the masses, better outreach which is always nice.
The only thing now i want is isro releasing the video of test fire of the SS1 of the SSLV.

Indian built S-band SAR on Gulfstream aircraft
The ISRO L- & S-band Airborne SAR (ASAR) instrument is a testbed for the NISAR mission. NASA and ISRO collaborated to conduct simultaneous collection of L- & S-band (24 and 9 cm wavelengths) Synthetic Aperture Radar (SAR) imagery over selected North American sites for the development and refinement of algorithms in advance of the NISAR Mission anticipated to launch in 2022. ASAR was repackaged for installation aboard the NASA’s C-20A (Gulfstream-III) and by utilizing the antenna pod and navigation package for the NASA UAVSAR radar system.
The North America ISRO-ASAR science campaign sites were jointly selected by NASA’s ASAR Science Team and ISRO’s NISAR science team to support Earth science and applications research topics. Phase 1 of the campaign took place from December 4–16, 2019. The science topics range from Cryosphere (glaciers, sea ice, freeze/thaw), Hydrology (soil moisture, snow, lakes/rivers), Earth Surface and Interior (lava flow geology, landslides, volcanic processes), and Terrestrial Ecology (biomass, agriculture, forest), Applications (oil spills), permafrost, and calibration/validation.

OneWeb receives Indian operating licence

OneWeb receives Indian operating licence
The question of whether India would ever refuse OneWeb an operating licence has never been in doubt. Now OneWeb has received its all-important Global Mobile Personal Communications by Satellite (GMPCS) licence.
The formal permission came from India’s Department of Telecommunications (DoT), paving the way for OneWeb to launch its broadband service in India later this year. The launch in India though is likely to get delayed beyond the initially expected May 2022 timeline, due to challenges brought by the ongoing Russia-Ukraine war and a severe slow-down in launching the remaining one-third of its satellite fleet.
OneWeb’s largest shareholder is Bharti Group. OneWeb has about 428 satellites in orbit out of a target 600 needed for a near-global service.
Timing is everything for the embryonic service, and India’s massive potential recognised by plenty of would-be rivals.
For example, SpaceX’s Starlink service was warned – and lost its CEO – when it emerged that it was soliciting subscribers without an operating licence.
In February a major rival to Bharti emerged in the shape of Mukesh Ambani-owned Jio Platforms (JPL) which partnered with Luxembourg’s SES to deliver fast broadband from space services across India and neighbouring markets using its geostationary (GEO) and medium earth orbit (MEO) satellite constellations. A separate Jio arm has also applied for a GMPCS licence.
Besides Starlink there’s also the Jeff Bezos-backed Amazon/Project Kuiper scheme, although not a single Kuiper satellite has yet launched. There’s also India talk from Ottawa-based Telesat which is in discussion with another giant Indian conglomerate, Tata Group.

Failure analysis report of F10 failure

GSLV-F10/EOS-03 Mission Failure: Failure Analysis Committee submits conclusions & recommendations
The GSLV-F10/EOS-03 Mission lifted-off normally from Sriharikota on August 12,2021 at 0543 hrs after a smooth countdown of 26 hours. In the flight, the performance of the first stage (GS1), the strap-on stages (L40) and the second stage (GS2) were satisfactory and in accordance with the pre-flight predictions. However, the onboard computer aborted the mission at 307 seconds into the flight leading to mission failure.
Initial investigations with the post-flight data conducted immediately after the launch indicated that an anomaly in the Cryogenic Upper Stage led to the mission abort. A National level Failure Analysis Committee (FAC) consisting of experts from academia & ISRO, was constituted to identify the causes of the anomaly and to recommend corrective actions for future missions. The FAC has thoroughly reviewed the flight data along with all data related to the activities ranging from the stage preparation at the launch complex, countdown to lift-off. The Failure Analysis Committee recommended a series of computer simulations & confirmatory ground tests to simulate the conditions very close to the GSLV-F10 flight scenario and validate the findings of the Committee. Subsequently, the respective teams have completed the simulations & ground tests and presented the results, based on which FAC has completed its deliberations and presented its findings and conclusion on March 24, 2022.
The time line of flight events and major observations on the Cryogenic Upper Stage in the GSLV-F10 mission along with all previous GSLV missions, were thoroughly discussed and deliberated. FAC observed that a deviation in performance of the Cryogenic Upper Stage (CUS) was observed at 297.3 sec after lift-off due to which the onboard computer aborted the mission at 307 sec.The ground servicing of the Cryogenic Stage was normal and the required lift-off conditions were achieved. However, subsequent to lift-off, the Committee observed that the build-up of pressure in the propellant (Liquid Hydrogen or LH2) tank during the flight was not normal leading to a lower tank pressure at the time of ignition of the engine. This resulted in anomalous operation of the Fuel Booster Turbo Pump (FBTP) mounted inside the LH2 tank which feeds the main turbopump of the engine resulting in insufficient flow of Liquid Hydrogen into the engine thrust chamber. Detailed studies indicate that the most likely reason for the observed reduction in LH2 tank pressure is a leak in the respective Vent and Relief Valve (VRV), which is used for relieving the excess tank pressure during flight. Computer simulations as well as multiple confirmatory ground tests, closely simulating the conditions in the GSLV-F10 flight, validated the analysis by the FAC.
The FAC concluded that the lower LH2 tank pressure at the time of CUS engine ignition, caused by the leakage of Vent & Relief Valve (VRV) resulted in the malfunctioning of the Fuel Booster Turbo Pump (FBTP) leading to mission abort command & subsequent failure of the mission. The most probable reason for the leakage of VRV valve is attributed to the damage in the soft seal that could have occurred during the valve operations or due to contamination and valve mounting stresses induced under cryogenic temperature conditions.
The committee has submitted comprehensive recommendations to enhance the robustness of the Cryogenic Upper Stage for future GSLV missions, which includes an active LH2 tank pressurization system to be incorporated to ensure sufficient pressure in the LH2 tank at the appropriate time before engine start command, strengthening of Vent & Relief Valve and associated fluid circuits to avoid the possibility of leakage along with the automatic monitoring of additional cryogenic stage parameters for giving lift-off clearance .
