The next launch from

The Indian Space Research Organization (ISRO) has carried out the first integrated test of an intermediate configuration of its 2000kN Semicryogenic Engine at its newly commissioned Semicryogenic Integrated Engine & Stage Test facility at the ISRO Propulsion Complex.
If we increase the Mk-3 production rate to 6 as Somnath sir said then we can completely replace Russia in the commercial launch industry. With Mk-3's back-to-back commercial launches we have shown our intent and capability now we just need to accelerate the Mk3 production rate.
In 2023,
@ISRO
decided to provide access to remote sensing data from 44 satellites dating back to 1986. Would you like to know the peculiar reason behind this decision, or why the government forced ISRO to do so?

Here is the reply to another RTI that I filed in January 2024:
> The first unmanned flight of Gaganyaan will carry both the crew module and service modules.
> The objective of the first flight is to validate all critical hardware required for the mission.
That's very true. In just two years, we will see a Chinese private company launching a reusable rocket more powerful and efficient than ISRO's rockets. If we progress at ISRO standard pace, we will continue to play catch-up forever.
👉 Ten out of twelve transponders are assigned for the South Asia satellite. Only Bhutan, Bangladesh, and Maldives have established ground infrastructure for utilizing the South Asia satellite.

This is how the fully stacked crew module will look after service module integration. It will measure 3.58m in height, 3.5m in diameter, and weigh around 8200kg.
Now some important questions about the Gaganyaan program:
👉 Even though
@isro
is developing its own Intra Vehicular Activity (IVA) suits but for Gaganyaan mission
a well proven and time tested Russian spacesuit will be used.
Elena Geo Systems, a Bengaluru-based space tech company, has designed and developed an indigenous Navic chip. They have already received an order of 10,000 chips, which will be fabricated in Taiwan.

👉 Regarding SSLV We will continue to see very few launches of SSLV as mass production will only start after isro complete transfers of technology to the private industry.
👉 In one interview Somnath Sir stated that India currently lacks the capability to manufacture the crew capsule. As per
@isro
they are exploring both internal and external routes to realize the crew module hardware.
The test is a major milestone before integrating the complete engine and its qualification. The Liquid Propulsion Systems Centre of ISRO is designing and developing the engine with Indian industry participation,

Public at 7pm today.
ISRO has had a very extensive remote sensing program over the years. ISRO successfully pioneered remote sensing instrument capabilities worldwide, and to this day, we have some of the highest resolution satellites in space.
and it will power the booster stages of future launch vehicles using the Liquid Oxygen-Kerosene propellant combination. The newly established test facility is capable of testing semi-cryogenic engines up to 2600 kN thrust
Geosynchronous Satellite Launch Vehicle (GSLV) has been launched 15 times: 6 times with 🇷🇺 cryogenic engines and 9 times with indigenous cryogenic engine. Out of these 9 were successful launches 4 were complete failures and 2 were partial failures.
GSLV-F14 getting ready for launch on 17th it will place INSAT-3DS metrological satellite in Geo transfer orbit. INSAT-3DS will complement the existing INSAT-3D and INSAT-3DR satellites.

To understand the demand, I submitted a RTI request to National Remote Sensing Centre (NRSC) to understand the utilization of the products. It is well understood that the majority of the utilization of these products is internal to ISRO and the government.
In response to the RTI I filed in January 2024 where I had requested the amount invested in R&D from the financial year 2001-2023 but they just provided me from 2020-2023.

Thread on Iraqi Launch vehicle
Al-Abid:
In the late 1980s Iraq initiated a program to develop a satellite launch vehicle with the aim of placing a 100-300 kg payload into a 200-500 km orbit thereby aiming to become the first in the Arab world.
Even then, the revenue doesn't match the satellite's cost.
For example:
Let's consider Resourcesat-2, India's most successful remote sensing satellite, with a successor in Resourcesat-2A. Now, whether it is really successful or not, we will decipher.
A glorious 23 years of flawless service with zero crashes comes to an end. No worries, we need to figure out what went wrong fix it and improve.

@isro
can you please use CY2 OHRC to click some pictures of the
@ispace_HAKUTO_R
landing site? It's a small request from the Indian space community.
Here's how the fully stacked SCE-200 will look. While it is true that the sce-200 is based on the ukrainian RD-810 engine, it is important to note that the RD-810 has never been used in an actual flight.

We sent India £33.4 million in foreign aid cash in 2022/23. But the total is set to rise to £57 million in 2024/25.
Anybody think we should send money to India?
Or no we shouldn't & agree with me, charity starts at home?
But now let's calculate the cost of:
Making,
Launching, and
Maintaining.
According to media reports, the cost of the Resourcesat-2 satellite is 200 Crore. Adding to that the launch cost of 90 crore and maintenance cost of 10 crore for ground stations, commanding, downlinking,
On average, 3-3.5 crore of this revenue comes from the combination of both Resourcesat-2 and Resourcesat-2A. Out of ISRO's approximately 30 satellites, 2 of them generate more than 30% of the revenue. This is likely why ISRO continues to refer to them as successful.
The total revenue would be 27 crore. So, ISRO actually made 27 crore INR in the last decade by investing a cost of 600 Crore INR. Now, think, is it really successful? There isn't enough demand in the country (or elsewhere, because NRSC also sells data to outside the country too)
ISRO successfully completed final hot test of human-rated L110-G stage Vikas engine for Gaganyaan program marking a major milestone in India's human spaceflight program.
It's not about race, but rather about the actual scientific contributions toward understanding our closest celestial body whether CY-3 lands near south-pole before or after luna-25. We Indians will share the same amount of happiness and pride.

The data still seems to be coming (kudos to exceeding the satellite's lifetime). The first satellite was launched in 2011 and the second satellite in 2016.
Let's assume they actually sold 3.5 crore data every year from 2016-2021 and 2 crore data every year from 2011-2016.
@RVCJ_FB
This is misleading and incorrect the said details is about CH-3 orbiter not CH-3 lander. The lander just had 490 Liters of fuel and survival on moon doesn't depends on fuel but battery and solar panels.
Important Next 5 Years for
@isro
and What We Can Expect:
1. Indian vyomanaut on board the ISS.
2. Approval for Shukrayaan and Lupex by 2025.
3. MK-3 with SC-120 stage
4. NGLV design Finalisation.
5. 4th country in the world with independent human spaceflight capability.
for the satellites they build to compensate the cost incurred by taxpayers. The sad part is that , CAG did this analysis and already identified this problem in 2011 itself before the launch of first satellite.
A major upcoming milestone in the Chandrayaan-3 mission which will involves the separation of Vikram lander from the Propulsion module. During this event Vikram will bid adieu to the PM after separation vikram will perform two deorbit burns to achieve the 100*30 km orbit.
archiving, and salaries to scientists (which I've estimated conservatively), it would amount to a total cost of 300 crore. 2 satellites would cost 600 crore. Both of these were planned for a 5-year lifetime.
