(1/9) Most of us know the rocket engines used on #ISRO's rockets. But not as many know the smaller engines they built for use on their satellites to perform precise orbit raising/trajectory correction burns.

Let's get familiar with some of the lesser known engines of ISRO 🧵

(2/9) But first we gotta learn a few terms. A rocket engine runs in Blowdown or Regulated mode.

In Blowdown mode the propellant is pressurized with a fixed amount of helium. So as prop. is consumed, the pressure in the prop. tanks decreases.

(3/9) But in Regulated mode more Helium is continuously added to the tanks to keep a constant internal pressure.

Knowing this is important as it tells you if a spacecraft needs pressurant tanks in addition to prop. tanks.

Okay let's see the engines-

OneWeb Constellation Summary:

OneWeb Constellation operates in a LEO Polar Orbit. Satellites are arranged in 12 rings (Orbital planes) with 49 satellites in each plane. The orbital planes are inclined to be near polar (87.9 Deg.)

The orbital planes are 1200 km above the Earth. Each satellite completes a full trip around the earth every 109 minutes. Theearth is rotating underneath satellites, so they will always be flying over new locations on the ground.

@gauravcsawant

RB Sreekumar, former Gujarat top cop, accused of fabricating evidence in #Gujaratriots case is also accused of framing #ISRO scientist Nambi Narayanan in a false espionage case.
The year was 1994.
Sreekumar was then working as Dy Dir Subsidiary Intelligence Bureau (SIB) in Kerala

Narayanan was working on the cryogenic engine technology at #ISRO. He was falsely accused of selling top secret documents to foreign handlers including in #Pak. The aim was to arrest The scientist & sabotage India's efforts to make cryogenic engine.
The scientists were *tortured*

The High Court said there was not even a *scintilla of evidence* regarding the scientists being influenced by any foreign power.
Supreme Court in 2018 said the case against Nambi Narayanan was malicious & awarded a compensation of Rs 50 lakh. Narayanan was a successful scientist

@BaluSreevidya

From my memory of what I learned from my father on ISRO and @NambiNOfficial

The day the news came out in Kerala Newspapers calling NN a traitor, my father said a person like him can never be a traitor. Something with that name too.

Political vendetta and CIA behind this.

1. Rajiv Gandhi wanted India to develop cryogenic engines in India. CIA as expected said no.

They didn't leave it at that. When Russia was willing to help India, CIA wanted to ensure this did not happen.

2. Antony and Ummen Chandy were conspiring against K Karunakaran, the last

Hindu Chief Minister of Kerala. They used State Police for their nefarious plan.

What CIA orchestrated through their assets and State Police became a good plot for Antony-UC league to bring KK down.

Mariam Rasheeda, known to be a CIA agent later on was brought in from

#ISRO truck blocked in Kerala!
Reason why India’s TIP (Kerala) is kept so rogue! #PortStates
Pls read d thread!🙏

On sunday workers union demanded “gawking wages” for an ISRO truck.
A practice where headloaders charge money for STARING at people loading/unloading cargo.🙄

2/10 It’s a banned practice yet workers union protested for it. This is jst ONE example of hw c0mmies work. They create a ruckus when not provided gawking wages. A #sinister practise to make KERALA an UNDESIRABLE location for investments.Ports of KERALA face similar issues.

3/10 Why ports of Kerala r so important? India is well placed geographically and since ancient times we hv hd ports which helped India prosper. Why did #VascoDeGama arrive in Kerala? Kerala was always an opening to Indian subcontinent. Thats why! (Pic: yozivag)

And…. it took off today. 👍 #ISRO has posted update: “Performance of 1st and 2nd stages was normal. However, Cryogenic Upper Stage ignition did not happen due to technical anomaly. The mission couldn't be accomplished as intended.” Will have to wait to see the impact of this.

ISRO’s GSLV failed to put EOS-03 in orbit. This launch was to be followed by other launches.

This was the 14th launch of GSLV and 4th failure. Last time GSLV developed anomaly in 2010. indianexpress.com/article/explai…

This is how #JoeBiden hurt #ISRO. 👇There were back to back attempts to sabotage ISRO’s projects. My video about—Joe Biden, ISRO & a SPY RACKET.👇 This man if elected will not jst side with China, bt will impede INDIA’s growth. The spy racket is a proof!!

This is y Joe Biden is wrong for India.

Now the question is was there an attempt to sabotage Chandryaan-2's launch also? Only time will tell.

Adding this tweet thread here, coz it proves how Joe has been consistently pro-China.
