@AgniVesa_07 @GoI_MeitY @MIB_India @HMOIndia Why don't you guys do something about these racist accounts and fake propaganda against Indians? Why not issue legal notices to @X and @nikitabier for amplifying these accounts and letting them continue unchecked?

[NASA Administrator Jared Isaacman @NASAAdmin]

We go where we need to be, and today that was @NASAKennedy.

Some of my senior engineers and I spent time at @blueorigin with @JeffBezos and @davill, speaking with the workforce and seeing the damage at LC-36 firsthand. I appreciated the opportunity to hear directly from those working through the aftermath and better understand the challenges ahead.

There is a lot of work to do, but this is exactly why people choose careers in aerospace, whether at NASA, Blue Origin, or across the industry. The talent in this field thrives under pressure and performs at its best when solving the toughest problems.

We have been saying for months at NASA that we are not going to sit on our hands and wait for the capabilities necessary to achieve the nation’s most pressing objectives. We are going to take an active role alongside our partners, just as we did in the 1960s, to overcome setbacks, remove obstacles, and deliver the intended outcomes.

@NASA is committed to helping the Blue team recover, continue to advance their lunar lander and get New Glenn back to launching as soon as safely possible.

America’s greatest achievements in space were never the result of avoiding setbacks. They came from overcoming them. We have done it before, and we will do it again🇺🇸

Here's our video of the explosion at Launch Complex 36. It happened about 9 pm ET (0100 UTC) as Blue Origin was beginning a static fire test of its New Glenn rocket.

[Blue Origin @blueorigin]

We experienced an anomaly during today's hotfire test. All personnel have been accounted for. We will provide updates as we learn more.

Liftoff of Starship!

[AgniKul Cosmos @AgnikulCosmos]

Humbled to share that we successfully test fired 4 semi-cryogenic rocket engines simultaneously, as a cluster.

All the 4 engines are 3d printed as single pieces of hardware - designed and manufactured in-house at AgniKul Cosmos Rocket Factory - 1. As with all our propulsion systems, these 4 engines are also powered by electric motor driven pumps.

This test involved calibrating 8 pumps, 8 motors and tuning 8 speed control algorithms to work together in perfect sync to achieve uniform startup, steady state and shutdown performance across the entire system. As with the last cluster test, to the best of our knowledge, this is the first time such a test has been performed in India with semi cryogenic engines.

We are extremely grateful to have the opportunity to be building world class, original space technology from India, for the world with the support of @iitmadras @isro and @INSPACeIND

From here on, the addition of engines to our clusters will likely increase non-linearly. #Agnibaan #RocketEngineCluster #ElectricPumpFedEngines #Agnilet #SinglePieceEngine #3dprinting #RocketEngineTest #AdditiveManufacturing #Agnikul #AgnikulCosmos #StartupIndia #MakeinIndia #madeinIndiaForTheWorld

India's CDAC & UAE’s G42 agree to build one of the world’s most powerful supercomputers, an 8 Exaflop machine, to boost India’s artificial intelligence programme.

[Dhruva Space @DhruvaSpace]

🇮🇳 Excited to share that #DhruvaSpace has secured INR 105 Crores #RDIF backing to develop ‘Project Garud’, advancing India’s Private-sector 500 kg-class Satellite capability for constellation-scale missions.

[DRDO @DRDO_India]

DRDL Hyderabad has conducted second successful extensive long-duration test of Actively Cooled Full Scale Scramjet Combustor, achieving a run time of over 1200 seconds at its state-of-the-art Scramjet Connect Pipe Test (SCPT) Facility on May 09, 2026. This is major advancement towards Hypersonic Missile Programme

[DRDO @DRDO_India]

Advanced Agni missile with MIRV (Multiple Independently Targeted Re-Entry Vehicle) system was successfully tested from Dr. APJ Abdul Kalam Island, Odisha on 08th May 2026.

The missile was flight tested with Multiple payloads, targeted to different targets spatially distributed over a large geographical area in Indian Ocean Region.

@Astro_Neel @thesuyashsingh ...If the antenna periodically points toward and away from earth the received signal strength would naturally rise and fall in a repeating pattern maybe even without catastrophic instability

[Ankur Tripathi @_ankurtripathi_]

@Astro_Neel @thesuyashsingh The cyclic signal variation could simply result from antenna gain and polarization changes as its orientation changes relative to the ground station...

[Ankur Tripathi @_ankurtripathi_]

@_phnx_1 @Astro_Neel @thesuyashsingh People online are over interpreting amateur telemetry without access to its actual attitude data... especially since ACS tuning in orbit is extremely difficult and sensor calibration can behave differently in real space conditions :(

[Ankur Tripathi @_ankurtripathi_]

@Astro_Neel @thesuyashsingh ...Could this rotation simply be part of the normal detumbling and commissioning phase ?? or might it indicate some issue during separation or attitude stabilization?

[Ankur Tripathi @_ankurtripathi_]

@Astro_Neel @thesuyashsingh Rotation rate of about 0.052 rad/s (~3°/s) is not catastrophic but obviously SAR imaging requires extremely accurate pointing stability... So eventually the satellite would need to become highly stable for proper OptoSAR operations...

[GalaxEye @GalaxEye]

Mission Drishti Update : Contact with the satellite is firmly established.

[Sarvam @SarvamAI]

We are excited to announce that Sarvam is partnering with @PixxelSpace to power the AI backbone of India's first orbital data centre satellite.

This is a first for the country, with India-built AI models running on an India-built satellite and both training and inference happening directly in orbit, without any dependence on foreign cloud or ground infrastructure.

[ISRO @isro]

Congratulations to GalaxEye on the successful launch of Mission Drishti!
A significant milestone in India’s space journey, with
world’s first OptoSAR satellite and India's largest privately built satellite, advancing all-weather Earth observation capabilities.

ISRO is proud to support this achievement by enabling access to its satellite testing facilities fostering innovation and handholding India’s emerging private space sector.

Best wishes to the team at @GalaxEye for continued success in strengthening the nation’s space ecosystem and advancing cutting-edge technology.
