Video: Skyroot tests retro engine of Vikram-1 that will trigger stage separation
Skyroot Aerospace has successfully completed the developmental tests of the Vikram-1 rocket's retro motors as it steps closer to India's first privately built orbital rocket Hyderabad-based startup announced that all six firings of these retro engines met their target thrust and differential delay specifications, ensuring a smooth and reliable separation of the rocket's first stage during retro motors, the smallest solid propulsion units on the Vikram-1, play a crucial role in the vehicle's multi-stage retro motors successfully completed the developmental tests! The smallest solid motors on the vehicle they're vital for clean separation of Stage 1. Six firings confirm they are hitting all target thrust and differential delay specs for a smooth jettison. Skyroot Aerospace (@SkyrootA) May 27, 2025advertisement During ascent, these motors fire to decelerate the spent first stage, enabling a clean jettison and minimizing the risk of collision or debris between stages. This stage separation is a critical maneuver in any multi-stage rocket, directly impacting mission reliability and the safety of payload recent tests, conducted as part of a broader series of qualification campaigns, included six successful static firings. Each test validated the motors' ability to deliver precise thrust and timing, both vital for ensuring that the first stage separates cleanly from the rest of the company emphasised that these results mark a major step forward in preparing the Vikram-1 for its maiden orbital flight, expected later this year."In that critical window, precision takes over: four jettison motors start firing in perfect sync within milliseconds, delivering nearly 10 tons of retro thrust for about a second to counter residual force and cleanly push Stage-1 toward Earth, avoiding collision with Stage-2. This precise maneuver minimizes the no-control zone, ensuring a smooth transition before Stage-2 ignites and takes command of the mission," Pawan Kumar Chandana, Co-founder and CEO of Skyroot Aerospace Vikram-1, designed to deliver up to 480 kg to low Earth orbit, features three solid propulsion stages and advanced systems for stage separation and trajectory control. With the retro motors now flight-proven, Skyroot is one step closer to joining the ranks of private companies capable of launching satellites into orbit—a landmark for India's burgeoning private space Watch

Skyroot successfully tests stage separation system for Vikram-1 rocket
Hyderabad: As spacetech startup Skyroot Aerospace gears up for the launch of India's first privately built orbital rocket , Vikram-1, into low Earth orbit (LEO) later this year, the company achieved yet another milestone. It successfully tested the stage separation system of the rocket. As part of this, the Hyderabad-based startup tested the separation of stage 2 of the rocket from stage 3. "Clean separation, smooth execution! Our team just nailed the stage separation test of Vikram-1. The ultra-low shock pneumatic separation system we developed in-house worked like a charm, smoothly separating Stage 2 from Stage 3 – in another boost to our journey to orbit!" Skyroot Aerospace said on social media platform X. "Imagine separating two rocket stages in space within a few milliseconds – without generating a shock – pulling them apart by 1.2 metres with just a few cms of clearance between the nozzle and internal fuel tanks and propelling the separating stage with enough energy to reach the required jettisoning velocity within 0.2 seconds. This is what it takes to separate rocket stages in the deep vacuum of space – and we've now qualified our proprietary stage separation and jettisoning system for flight. Another critical milestone on the path to the launch of Vikram-1," Pawan Kumar Chandana, Co-founder & CEO, Skyroot Aerospace, announced on X. The latest test is part of the battery of tests conducted by Skyroot over the past couple of months in preparation for the launch of Vikram-1 later this year. These include the structural rigidity test of Kalam-1200, the carbon composite stage-1 motor that is touted as the longest monolithic motor casing developed in India using Skyroot's proprietary filament winding process. Kalam-1200 will propel Vikram-1 from the ground through the Earth's atmosphere. The startup also tested Raman 50N mini thrusters that will be integrated into Vikram-1's orbital adjustment module and provide pitch and yaw control during flight. Earlier in May this year, Skyroot also qualified Vikram-1's interstages, which are four load-bearing structures that will house the avionics, separation systems, and critical sensors and will play a key role in maintaining the structural integrity of the rocket throughout its ascent into orbit. In April this year, Skyroot also ran pre-flight tests on the mission computer of the launch vehicle as well as the composite nozzle and flex nozzle control system of Kalam-1200, the first stage of the rocket.

ISRO mission fails as PSLV suffers third-stage anomaly
New Delhi: In a rare failure, India's main rocket PSLV developed problems a few minutes after take-off and failed to place earth observation satellite EOS-09 into the intended orbit in an early morning launch on Sunday. In a short statement, ISRO said the problem was observed in the third stage but did not give any details. 'Today's 101st launch was attempted. PSLV-C61 performance was normal till second stage. Due to an observation in the third stage, the mission could not be accomplished,' ISRO said. This was the 101st mission launched by ISRO, and the 63rd one using the PSLV rocket, which is the most successful launch vehicle developed by India's space agency. PSLV has failed on only two earlier occasions, the first time during its inaugural flight in 1993 and then in 2017 when the C-39 mission had been unsuccessful. 'Heartbreaking to see a failure in PSLV today. I still remember my time at ISRO and how shaken we were when PSLV-C39 failed in 2017 after more than two decades of successful flights. It's a powerful reminder of how complex and unforgiving spaceflight can be, even for proven workhorses like PSLV,' said Pawan Kumar Chandana of Skyroot, a private space company that is developing its own launch vehicles.

Skyroot Aerospace en route to Earth orbit
As soon as the exam ended and the bell rang, what did we do with our question papers? Some of us tossed them back in our bags to foretell our marks, while others fancied themselves to be Picassos and Van Goghs, turning the sheets into their personal doodle pads. But then there were those who meticulously folded the paper to create rockets, pretending to be India's top scientists before the next period started. Because rockets — they're fascinating, aren't they? Well, Pawan Kumar Chandana's fascination skyrocketed to the point where he, along with his friend Naga Bharath Daka, founded Skyroot Aerospace, which launched India's first privately developed rocket. A former ISRO scientist and IIT Kharagpur alumnus, Pawan now leads a team of over 350 individuals building world-class launch vehicles. He speaks with CE about Skyroot's ascent, Vikram-I, and what lies ahead. Excerpts Skyroot is very clear about its mission to 'open space for all'. In an era where many are looking to 'conquer' space, where does this thought come from? Space was always meant to be a place to explore, learn from, and utilise thoughtfully to improve lives on Earth. Astronauts say that from up there, you don't see boundaries and regional differences, but just this beautiful blue marble that sustains life like no other planet we know of. Earth is a unique place in the vast galaxy, and what we achieve in space, be it through satellite communications or deep space exploration, should be for the benefit of all on Earth. Our purpose at Skyroot is to enable this by democratising access to space. Once we remove the barriers to space for nations, startups, and even universities alike, we can build incredible technological solutions that can impact how we live, communicate, irrigate, plan our cities, protect the environment, and more. This one is for our curious readers — why the name 'Skyroot'? We aim high and soar skyward — not for the sheer thrill of it, but for the very rooted belief that what's up there improves lives on Earth. Were you always interested in space? I come from a very humble family. Good values and good education were the dinner topics; space at the time felt so far off. But as I grew up, my deep passion for technology and the cosmos grew. Even as rockets fascinated me, I did not know that I would one day be building them. The turning point was at IIT-Kharagpur. I came to know that ISRO was coming to the campus for recruitment. At that time, most IIT students preferred to join consumer tech companies or global software giants, and even ISRO did not frequent IITs so often. But my single-minded focus then was to join ISRO, because I knew space was my calling. You were a scientist at ISRO for several years. How was your stint there and what fuelled you to set up Skyroot? The six years I spent at ISRO were incredibly rewarding. It was a fulfilling dream to be part of building a rocket. I had the opportunity to be part of the team that built the biggest rocket ISRO was then developing — the LVM3, or the Bahubali rocket. ISRO was also a great vantage point to observe how the rest of the world was developing their space technologies. I could see the rise of private companies in the US and other countries, which were building rockets innovatively and cost efficiently. Private space programmes were broadening the horizon of who could access and build for space. I could see how the future of space was evolving. And yet, there was no Indian private company building rockets. So, I found the second chapter of my space calling. In 2018, my friend Bharath and I started Skyroot. We wanted to build an Indian company that could go global and develop rockets for the world. In 2022, Skyroot launched India's first privately developed rocket, Vikram-S. And recently, you test-fired Kalam-100, the third stage of Vikram-I. Can you tell us more about this? As the saying goes, it is rocket science — it is incredibly challenging. Numerous systems and subsystems have to sync in perfect harmony for a rocket to launch successfully. You have to test and test again until you perfect every small aspect of a rocket. And even then, there are external challenges such as unexpected weather. The margin of error is very slim. The true test is to launch a rocket. And that is what makes Vikram-S special. It was a validation for the technologies that we had developed at Skyroot. It was our small writing in the sky to showcase where we have reached, and where we plan to go further. Now, we are preparing to validate the second part of that, i.e., where we plan to go. With Vikram-I, we aim to place satellites from across the world into Earth's orbit. No private company in India has done this before. So, we have to test every aspect of this seven-storey-tall rocket before placing it vertically on the launchpad. This includes static fire of all the three solid stages, numerous short and long duration firing of the liquid engines, and more. In the recent test, we fired the third stage of the rocket called Kalam-100, which is designed to operate completely in space. The test evaluated its ballistic performance, thermal insulation, nozzle actuation, and other key parameters — and it was a great success. For the uninitiated — what does it take to build a rocket? Audacity and perseverance. Of course, there is a lot of technological innovation and iterations involved. But building a rocket is not a linear journey. No rocket has ever been built without some failure or another. You will face setbacks on the way. You have to learn from them just as you do from your successes. At Skyroot, we have been fortunate to have built a team that is as passionate as any of us are on this mission. What are the common challenges that startups in the space sector face, and what advice do you have for them? Space-tech endeavours are time- and capital-consuming. There will be setbacks and challenges that will test you. It is important to maintain a consistent long-term perspective when crafting strategies, rather than succumbing to the allure of short-term gains. That's my advice to entrepreneurs starting out as well: stay resilient and stay true to your trajectory. A rocket doesn't take a straight line to space... building a space startup is a similar journey. How can we cultivate the interest of children and youngsters in space? Science fiction movies and books have done wonders in sparking interest in space among young minds. Beyond that, we need to make space education more accessible and engaging. Schools can incorporate space-related topics into their curriculum, organise visits to research institutes and startups, and invite professionals from the space industry. The young minds should get an opportunity to see and work with technology. Can you tell us about the upcoming goals you have? Future launch vehicles, such as Vikram-II, are being developed. Our immediate goal remains the maiden flight of Vikram-I, slated for the second half of this year, and to learn from that to make further improvements to the launch vehicle. With Vikram-I, we want to offer satellite launches into a variety of orbits at a high frequency. If all goes well, you are going to see a lot of Vikram-I launches from India in the coming years.
