This is incredible, since this launch was just 5 months ago and they did all failure analysis and improvements in just 5 months. And this is very fast in rocket industry.
@@jigsaw2281 bhai unhone bola ki ye bahut hi acchi chij hai ki ISRO sab kuchh public ke liye available kara uske kaaran hum abhi video dekh paa rahe hai
Wow, watched your video after some time. Amazed by your experience. And perplexed by the processes in place by ISRO. I can definitely take some inspiration in my Software Engineering designs from this!
6:47 It clearly depicts how that net like structure helps in minimising the weight without compromising structural rigidity. It's a good idea to make a video on design and manufacturing aspects of isro's rockets and how they are manufacturing them.
Whoa that'll put lot of loading on lower stage tanks! Anyways I was wondering how (and who) manufacture these high melting point superalloys to fabricate intricate parts like fuel pumps and injector nozzles etc. Would be great if you make a video on that.
Its good to see how ISRO is publishing reports in public and explaining criterias Its well known for the tax payers also .... Hopes for the next SSLV launch 🤞
आसान भाषा में रॉकेट के टेक्निकल terms को बहुत ही सही explain किया है। बस एक correction - rocket में initial phase me open loop guidance ke peeche ka मुख्य कारण ये है कि यदि रॉकेट अपने पथ से ज्यादा विचलित भी हो जाए तो होने दे, क्योंकि correction ke चक्कर में atmosphere की वजह से रॉकेट टूट भी सकता है।
Chandrayaan 3 phir se delayed ho gya because isro ko pehele LVM-3 ko commercial missions k liye use Krna hai... Let's hope ki ish saal CY3 launch ho jaye 🙏
Good info bro. Your channel is probably the only one that goes into this much detail about our Space sector. Though I'm proud of what ISRO has been doing. I feel they should be more open, their communication with the public is poor to say the least. Look how NASA or SpaceX doing in that aspect. significantly more people are excited when they announce a new program, a now rocket, new tech,... therefore there is more interest in learning about space, rockets, etc. But in ISRO's case there is only a small community, who are interested in such things. I hope this changes in the times to come. I hope in that process more people be inspired and actually want to take up space tech, engineering and go on to become good engineers and scientists who will drive our country forward, we have a huge potential in this sector.
just look at videos of ISRO missions with title containing "failed", it has lakhs of views but successful missions have in thousands people love failures over success of others
Wow, so more then mechanical we do mistake in onbord logic system. But i am happy we learn from mistake ,and hope they not do same mistake in future development of rockets.
I went from over the top Indian space ship to down to earth technical explanation. It's refreshing to see reasonable people explaining things so reasonably.
I think it is more important for ISRO to share the failure investigation report publicly because it wants to do more commercial launches. No doubt ISRO launches are most economical but if any organisation is more transparent to customers then it adds to customers' confidence. I think report should have as much information as necessary not more not less.
Accountability is great.For a government organisation like ISRO,it's very decent time taken to give failure analysis.I am happy that they care about taxpayer's money
Sir please answer this question, What if we convert Vikram-S into a mack 5 missile. It is cheaper than other options. We just need to attach seaker and warhead to it. Please answer sir 👍👍♥️
already such missiles exist, redundancy ka kiya karoge, plus it will become difficult for skyroot to use some software as certain software only can be used for non defence. and missiles are not as simploe as attach warhead on SRB and fly, itna saimple hota toh sab karte na ?
Even if we did that, it would become a ballistic missile. India already has a comprehensive asensal of ballistic missiles(Agni series, K series, Pralay and Shaurya being the main ones).
Does SSLV use a relatively new technology for INS implementation, resulting in the possibility of incapacitating due to vibration as you mentioned? If not, then I believe the tech is already quite mature, and might have been used in PSLV or GSLV as well which are quite successful as we know. Then, how can one explain the failure of INS?
IANA scientist. I watched some video about how rockets can navigate by looking at the stars in the sky, called Star Tracker. Maybe this cannot be used because of the high velocity, bright sunlight, reflections from existing orbital debris, etc? If not for those factors (or if those can be overcome) that would be a very good backup navigation system capable of withstanding all kinds of flight path deviations.
NAVIC, magnetometers(3d compass) etc. Are state sensors (final state value) and most state sensors suffer from some inaccuracy which is corrected with sensor fusion of state sensors with delta sensors (rate of change of state) like accelerometers and gyroscopes. This is likely why NAVIC alone is not the preferred choice of guidance but it may be a somewhat reasonable backup in an emergency. If you are interested, I'd suggest reading up on algorithms used for sensor fusion like kalman filter. To be more confusing, accelerometers can act as both delta and state sensor. As state orientation sensor to point to direction of gravitational force which dominates all other acceleration in most of the common cases near a gravitational body, as delta sensor for magnitude and direction of acceleration (once gravitational acceleration is filtered out) to calculate change of speed and from that distance travelled. This could be an interesting topic for a video :)
The FAC summary actually says that the VTM bypass was programmed. "VTM ignition was bypassed as programmed since it could be a deterrent to the success of salvage option in some cases." And, the reason for transparency is apparent. :p
hi . thanks for this video. navic system data may need some relativistic correction, because there are many fast moving systems symultaneously. It will be very complex to choose which values to rely on. it is very fun physics why such things happen.
Thank you for the explanation. Give a download button to download this video instead of usual third party tool. People need to save this video for reference.
So looks like design is not challenged enough in isro, many things are assumed that too in a real launch, not a failure based thought. Not discounting all achievements by isro but i doubt top mgnt is listening any callout from bottom. Same issue was with nasa. Communication is only top to bottom. It works most of the time but not everytime.
Why the satellite at high altitude during injection time for example Apogee is 510km perigee is 520km but during injection of satellite isro telemetry shows 540 550km height why?will it lose height and comes to 510*520km orbit finally
Mujhe ek question hain: If Solid Rocket Booster dosent give throttling power then how they control the direction of rocket ? Is there a communication system on the rocket which helps ?
why isro telemetry display lshows for example perigee of 520km, Apogee of 525km and altitude of 540km during injection of satellite,my question is if the orbit of 520*525km then why it is injected at 540km height does it lose height and comes to orbit(520*525km)finally? I hope u understand please reply me

No that's for hot staging. They fire the 2nd stage while attached to 1st stage so no seperation retro rockets are needed

Indian arm forces do not prefer liquid fuel missiles due their maintenance and refueling,they prefer mostly solid fuel missiles.

Awesome Video GS, Well Explained
Excited for Upcoming D2 launch
Thanks!
Does the stage detach first and then the engine for next stage starts and rocket moves on or engine starts first and then detach the earlier stage ?
Detach, seperate, after time time fire
Let's Go SSLV D2 launch 🥳

If not, then I believe the tech is already quite mature, and might have been used in PSLV or GSLV as well which are quite successful as we know. Then, how can one explain the failure of INS?
Use new ins developed with MEMS Gyros and a different accelerometer

What is difference btwn semi cryogenic and cryogenic ? And why is so much diffrence in there fuel.

mast video tha .....well explained
Does the final stage stays in the same orbit of satellite for somedays before it decays?
Equipment Bay , not baby. You will find similar structures in PSLV and GSLV too
Bhai INS ka capacity increase nahi ho sakta kya? Jis se woh jaldi saturate naa ho.
GooD Video Pranav.
Bhai inko code ke mamle me thora aur redundancy pehle se sochna chahiye yha
Won't the finalstage damages operational satellites if it decays uncontrollably?
So looks like design is not challenged enough in isro, many things are assumed that too in a real launch, not a failure based thought. Not discounting all achievements by isro but i doubt top mgnt is listening any callout from bottom. Same issue was with nasa. Communication is only top to bottom. It works most of the time but not everytime.
What happens to finalstage after injecting satellites will the isro controllably(guided)deorbit or make it fall and burn in earth's atmosphere?
Stay in orbit for some time. After few months or years slowly decay and burn up on reentey
PLS do a video on this
Why the satellite at high altitude during injection time for example Apogee is 510km perigee is 520km but during injection of satellite isro telemetry shows 540 550km height why?will it lose height and comes to 510*520km orbit finally
