ARISS is plotting a course to continue our mission in the government and commercial space realm beyond the targeted decommissioning of the ISS in the 2030 timeframe. Read more about our activities in these infographics, and in a blog post at ariss.org.
I stand deeply humbled to receive the nation’s highest peacetime gallantry award from the Hon’ble President of India today. While this honour bears my name, it does not belong to me alone. It is a reflection of collective courage, quiet sacrifices, and unwavering commitment shared by countless individuals who serve the nation with selflessness. Representing India in space was the privilege of a lifetime. Wearing this medal today is an even greater honour, for I do so on behalf of my colleagues—those who worked tirelessly behind the scenes, who made sacrifices, and who believed in a mission larger than themselves and larger than any one individual. I extend my heartfelt gratitude to the Government of India and to the people of this country, whose love, encouragement, and boundless curiosity for space exploration continue to inspire me. This medal is not just a milestone; it is a responsibility—a reminder that our journey has only begun, and that we must work to ensure that the dream of space travel becomes accessible to many more Indians. Thank you for your trust and faith. Jai Hind. Jai Bharat. #shux #india #shubhanshushukla #space #ashokchakra
The ARISS-USA team couldn't have picked a better weekend to have a SPARKI event at KSC. We hosted educators with upcoming STEM contacts ... they learned how SPARKI kits help students explore wavelengths and ham radio, bringing hands-on STEM learning into the classroom. 📻✨

It was a historic Live Satellite (ISS) demo conducted amongst mesmerizing 12000 students! Thank you Vedic Mission Trust, AMSAT-INDIA & UPARC for giving me opportunity to carryout interesting Talk on ISS, ARISS Program, Ham Radio, followed by LIVE ISS Sat Demo. 73 @VU2EXP Rajesh
AMSAT INDIA & Upagrha Amateur Radio club (ISRO) participated in 25th Rashtra Katha Shivir Pransla Gujarat, India. Live Amateur Radio demo using the ISS X Band repeater. 12000 students witnessed this event. VU2EXP, Rajesh Vagadia from AMSAT INDIA at the antenna and VU2JEL, Balaji from UPARC (ISRO) are seen in this video. @PMOIndia @isro @ARISS_Intl @gagan_shux @Somnath176 @IndianAstronaut
Believe it or not- Everything you see in this frame is falling. 😅 When I first reached the International Space Station, I had this strange hesitation: if I let go of something, won’t it just fall? On Earth, that’s exactly what happens. In space, though, my early instinct was to politely hand over items to crew-mates (one of them is quietly smirking in the background at my dismal lens changing skills 😅) instead of just releasing them. The funny part? They were just as cautious at first—so we ended up passing things around like an overly careful game of “hot potato.” Here’s the catch: nothing actually falls away in orbit. As you see in this video if I let go of the lens, it doesn’t drop—it hovers. Why? Because both the lens and I are falling at the same speed around Earth. No relative falling = no “down.” This idea goes all the way back to Isaac Newton’s legendary thought experiment: imagine standing on a tall mountain and throwing a ball. Toss it gently—it arcs down nearby. Throw harder—it travels farther before dropping. Throw it so fast that as it falls, Earth’s surface curves away beneath it? The rate of drop matches the curvature of the Earth. Congratulations—you’ve just put that ball in orbit. It’s falling forever, but it never hits the ground. That’s what orbit really is: perpetual free fall. Astronauts don’t feel weightless because gravity has disappeared—gravity up here is still about 90% as strong as at Earth’s surface. We feel weightless because we and everything around us are constantly falling together. Floating in space is really just falling—forever. 🌍✨ #shux #iss #space #shubhanshushukla #isro #axiom4 #newton #tiborkapu
25 years ago today students at Luther Burbank School in Illinois made history with the world's first school-to-@Space_Station contact via amateur radio. Just weeks ago, another Illinois school—Lincoln Magnet—continued the tradition, helping cap off 2025 with 77 STEM contacts worldwide. From 1 to thousands: Inspiring the next generation! Congratulations to all involved!

Space reached Udaipur—and with it came imagination, curiosity, and a room full of fearless young dreamers. I had the absolute joy of being part of the play “Google Kar Le Re,” brought to life by an incredibly talented group of children who owned the stage with confidence and creativity. While my acting skills clearly didn’t come close to matching theirs, I couldn’t have asked for a better experience. Sharing the stage with them, laughing along, and weaving in my own journey was deeply fulfilling. More than anything, it was an opportunity to underline a belief I hold close to my heart: that audacious dreams, when paired with persistence, can take you far beyond what seems possible. If stories from space can spark even one young mind to look up, ask questions, and refuse to give up on their dreams, then every moment on that stage was worth it. Udaipur reminded me once again that the future doesn’t just watch the stars—it dares to reach them. #shux #space #shubhanshushukla #india #isro #kids
