  • Vikram 1 Mission Aagaman Successful

    Vikram 1 lifted-off as if in a hurry from the First Launch Pad on 18 July 2026 at 12:05 PM. It cleared the launch pad and headed to orbit and placed two satellites in orbit. We now have India’s first successful launch of a launch vehicle by a non-governmental entity.

    I live-tooted on Mastodon where things remain calm. People just went crazy on X. A stream of congratulations followed.

    Before lift-off

    I have been recovering after a surgery earlier in the week. Hence, my father was also at home. I casted the webcast on YouTube on my TV. I was active on WhatsApp, Mastodon, and X.

    The webcast commentary frequently spoke over the callouts. You could hear the callouts better on the X webstream. However, I was not able to cast the X webstream on the TV.

    The lift-off reached a hold 5 minutes before lift-off scheduled for 11:30 AM. We saw that it was a Navigation Monitoring Failure hold. After a few minutes of discussions, the Automatic Launch Sequence was re-started with the lift-off time set to 12:05 PM. There were some anxious faces in the Mission Control Center.

    Countdown and Lift-off

    I breathed the first sigh of relief when the countdown went beyond the 5 minute mark. As the countdown went into 5 second call outs to each second countdown to zero, there was a great sense of being part of history.

    I felt there was a brief pause before the launch vehicle leaped off the launch pad. Lift-off and clearing the launch pad was an important launch milestone. The launch vehicle had not exploded on or off the launch pad. That was an achievement!

    The camera angle immediately after lift-off felt weird. The cheers from the Skyroot Aerospace team went over the calls for MaxQ. The graphs were textbook for the first two stages.

    There were some beautiful on-board camera views. The blue Earth just beyond the plume of the solid stage was a sight to behold.

    Trouble (that did not affect the overall launch) seems to start after the Stage III cutoff. There was a combined coast phase where the spent third stage flew with the fourth stage. When the third stage separated, it seemed to push towards the fourth stage and hit it gently.

    There seemed to be worry also when there seemed to be a temporary loss of signal from the vehicle a little after fourth stage ignition and well before satellite separation.

    It may have been because the signal switch between Indonesia and Australia or because the stage may have rolled.

    We got back to images of the Earth in the background. There was another round of celebration. More followed when the satellites separated. The indications on the screen seemed to indicate they had planned somethings that didn’t work but they skipped mentioning them until they happened.

    Dawn of a new era of private Indian rocketeers

    The image of the Sun rising over the payloads seen through the Cosmic diamond was just a goosebump-inducing experience.

    I switched off the webcast after the end of the stream with the announcement of completion of a mission. I then hung out on X asking questions and listening to answers.

    Payloads

    Grahaa Space announced that it has achieved mission objectives.

    Cosmoserve Space said that “The robotic petals which were supposed to open could not do so due to an unusual settling of the petals which might have been caused by a combination of extreme space conditions.”

    There was nothing heard about the Skyroot’s SCOPE satellite.

    There was independent confirmation of mission success by Space Force.

    Congratulations and God Speed! Skyroot Aerospace.

    The live webcast was taken down and a new trimmed video was uploaded after the Prime Minister’s mobile number leaked on the live webcast.

  • Skyroot’s Historic Launch

    I understand if you could not be a part of history in 1980.

    I hope you will take the time to watch the attempt on 18 July 2026 at 11:30 am (IST). India’s launch of the first private sector-built launch vehicle from Sriharikota. Watch here.

  • Vikram 1

    Before the launch of Vikram 1, I wanted to put together what is known from various online sources about the launch vehicle and the various payloads that will fly.

    The first launch by a private launch vehicle from Indian soil is on the horizon. The latest NOTAM put out seems to point at a launch sometime after July 12 (and latest by August 4) from the First Launch Pad at Satish Dhawan Space Center, Sriharikota. NOTAMs can change. The first mission of Vikram 1 is the Flight Test 1 or Mission Aagaman (Arrival).

    [Update [10 July 2026]: The latest NOTAM puts the launch at after July 18.]

    Vikram 1 is a four stage launch vehicle. The first three stages are solid and the fourth stage is liquid. The first three stages are powered by the Kalam 1200, Kalam 250, and Kalam 100 engines respectively. The fourth stage is called an Orbital Adjustment Module is powered by four Raman 2 engines.

    Skyroot Aerospace has been building a launch vehicle since their first test of Kalam 5 in December 2020. Their subsequent tests tested out bigger size solid motors – the Kalam 250 in March 2024. They also worked on the liquid fuelled Raman 2 engines since July 2023.

    Visit the Skyroot Aerospace YouTube channel for some wonderful videos.

    Skyroot Aerospace’s first launch was the Vikram S. Named after Dr. Vikram Sarabhai—the father of India’s space program—it successfully reached a peak altitude of 89.5 km during its historic maiden flight on November 18, 2022, from the Satish Dhawan Space Centre. They launched from their own launch pad.

    There have been reports in regional media about the launch as the rocket segments moved from their factory in Hyderabad to Sriharikota. The fuel that the solid stages were to be used were to be filled at ISRO Solid Propellant Plant (SPP) at Sriharikota.

    Skyroot announced the payloads on 6 July 2026.

    Dcubed (Deployables Cubed GmbH) is a German NewSpace hardware manufacturer headquartered near Munich, specializing in in-space manufacturing and deployable space technologies. They are widely known for producing high-performance micro-actuators, release nuts, launch locks, and deployable solar arrays designed to maximize payload power while minimizing launch volume. Dcubed plans to demonstrate its proprietary space hardware technologies: the uD3PP (micro Dcubed Pin Puller) and the mD3RN (micro Dcubed Release Nut).

    Grahaa Space (legally registered as zSpaze Technologies Pvt. Ltd.) is a prominent Bengaluru-based Indian spacetech startup focused on Earth observation. Founded by former ISRO scientist Dr. Loganathan Muthuswamy and ex-IBM/Dell executive Ramesh Kumar V, the company is building an advanced constellation of nano-satellites in Low Earth Orbit (LEO) designed to stream near-real-time, high-resolution geospatial video data.

    Their first mission, Solaras S2 which flew on South Korea’s HANBIT-NANO operated by Innospace launched on December 23, 2025, from the Alcântara Space Center in Brazil due to a launch failure. This is their next mission.

    Cosmoserve Space is an emerging Indian space technology startup specialized in Active Debris Removal (ADR) and space sustainability. Founded in 2025 by former ISRO scientist Chiranjeevi Phanindra, the company is headquarted in Hyderabad. They are developing autonomous, robotic spacecraft designed to safely de-orbit dead satellites and dangerous orbital clutter.

    The founders page on the Cosmoserve website puts Skyroot’s founder Pawan Chandana as a Founding Partner. Pawan gets to play a role in both putting satellites in orbit and helping with their end of mission.

    Cosmoserve released their mission patch in a video on LinkedIn. Varun Guru posted a nice explainer on how the mission is expected to work on X.

    There is very little known about the satellite that Skyroot has built.

    Cosmos Diamonds is sending a lab grown orbit into space. Watch this video for more:

    I hope they also reveal the story behind the micro sculpture. I was able to find the website of the artist Ajay Kumar Mattewada.

    While the focus will primarily be on the launch vehicle, I had fun learning about these ‘payloads’ as well.

  • Skyroot Aerospace unveils Dhawan 1

    Skyroot Aerospace unveiled the Dhawan 1 cryogenic engine today.

    Skyroot Aerospace is a commercial launch vehicle service provider company based in Hyderabad. They hope to build a fleet of three small satellite launch vehicles called Vikram 1, Vikram 2 and Vikram 3. They hope to launch Vikram 1 in December 2021.

    Dhawan 1 is a cryogenic engine that uses liquefied natural gas (LNG) and liquid oxygen as cryogenic propellants. The company says that their engine is 100% 3D printed in India. This will form the last stage of the Vikram 2 rocket. Vikram 2 is capable of lofting 520 kg to Low Earth Orbit (LEO). Skyroot dedicated the engine to Prof. Satish Dhawan on his birth centenary.

    Today is Prof. Satish Dhawan’s birth centenary. He was a fluid dynamics expert who was director of the Indian Institute of Science (IISc), Bengaluru before becoming Chairman, ISRO after the death of Dr. Vikram Sarabhai, the founder of the Indian space program. He is credited with building up India’s communication and remote sensing satellite systems as well as development of India’s workhorse PSLV.

    India also has had a tough time working with cryogenic engines. It tried to procure cryogenic engines from Russia. This was blocked by the USA. Following this, India began developing an indigenous cryogenic engine in the 1990s. Following many failures atop the GSLV, it finally became successful only in 2014. ISRO has since developed a stable of cryogenic rocket engines. Given this history, Skyroot’s success is appreciable.

    They received a lot of attention in August 2020, when they became the first Indian aerospace company to test their Raman engine. Raman is the upper stage bi-propellant liquid rocket engine used for Vikram 1. Vikram 1 is capable of lofting 315 kg to Low Earth Orbit (LEO). A few days back they also fired the ballistic evaluation model motors of their solid rocket engines. They have shared the videos on their YouTube channel.

    I am waiting to watch a static fire test of this cryogenic engine and also the first flight of Vikram 1. Good luck to Skyroot Aerospace.
