ISRO gearing up for Gaganyaan mission's first abort test of crew escape system this month-end
Bengaluru (PTI): ISRO plans to undertake an inflight abort test of the crew escape system by this month-end using a test vehicle developed as part of the country's ambitious maiden human spaceflight venture Gaganyaan.
"Preparations are going on. All vehicle systems have reached Sriharikota (for the launch). Final assembly is progressing. We are getting ready for launch by the end of October," Director of Vikram Sarabhai Space Centre (VSSC) S Unnikrishnan Nair told PTI on Thursday.
"(With) this crew escape system, we will demonstrate (validate) in different conditions like high dynamic pressure and for transonic conditions," Nair added
Thiruvananthapuram-based VSSC is the lead centre of ISRO under the Department of Space.
An ISRO official said the crew escape system (CES) is the most important element in Gaganyaan.
According to ISRO officials, this month's launch of the test vehicle TV-D1 would be the first of the four abort missions of the Gaganyaan programme. It would be followed by the second test vehicle TV-D2 mission and first uncrewed mission of Gaganyaan (LVM3-G1).
The second series of test vehicle missions (TV-D3 & D4) and LVM3-G2 mission with robotic payload is planned next. The crewed mission is planned based on the outcome of the successful test vehicle and the missions in which no crew is on board, they said.
The test vehicle is a single-stage rocket, based on liquid propulsion, developed to validate the CES performance at different critical Mach numbers but Nair said it can be used for many purposes including space tourism.
"We are taking (the test vehicle) to transonic conditions. That means crossing the Mach number of one. We will go to something like Mach number of 1.2. That reaches around 12 km altitude. From there, the escape system will be activated, and that will go some 20 km, and from there the crew module will be released," he explained.
"This vehicle can be used for space tourism, if any industry is interested. Same vehicle can take a crew module to 100 km and then come back. That's possible. If anybody is interested, this vehicle can be used for that," Nair said.
The Crew Module is habitable with Earth-like environment in space for the crew. It is of double-walled construction consisting of a pressurised metallic inner structure and unpressurised external structure with thermal protection system.
It houses the crew interfaces, human centric products, life support system, avionics and deceleration systems. It is also designed for re-entry to ensure safety of the crew during descent till touchdown.
According to ISRO officials, the Gaganyaan project would demonstrate India's capability of taking a crew of two to three members to a circular orbit of about 400 km around the earth for a one-to-three days mission and bring them back safely to earth, by landing in a designated location in Indian sea waters.
The LVM3 rocket, the heavy lift launcher of ISRO, is identified as the launch vehicle for the Gaganyaan mission. It consists of solid stage, liquid stage and cryogenic stage. All systems in LVM3 are re-configured to meet human rating requirements and christened Human Rated LVM3 (HLVM3).
Nair said the LVM3 cannot be used for conducting tests to validate CES, saying it's an expensive rocket.

Deep societal faultlines persist despite 75 years of independence: Justice Ujjal Bhuyan
Judge cites denial of home to Muslim girl, opposition to Dalit women cooking mid-day meals
Hyderabad, February 23, 2026: Supreme Court judge Justice Ujjal Bhuyan has said that despite repeated affirmations of constitutional morality by courts, deep societal faultlines rooted in caste and religious discrimination continue to shape everyday realities in India.
Speaking at a seminar on “Constitutional Morality and the Role of District Judiciary” organised by the Telangana Judges Association and the Telangana State Judicial Academy in Hyderabad, Justice Bhuyan reflected on the gap between constitutional ideals and social practices.
He cited a recent instance involving his daughter’s friend, a PhD scholar at a private university in Noida, who was denied accommodation in South Delhi after her surname revealed her Muslim identity. According to Justice Bhuyan, the landlady bluntly informed her that no accommodation was available once her religious background became known.
In another example from Odisha, he referred to resistance by some parents to the government’s mid-day meal programme because the food was prepared by Dalit women employed as cooks. He noted that some parents had objected aggressively and refused to allow their children to consume meals cooked by members of the Scheduled Caste community.
Describing these incidents as “the tip of the iceberg,” Justice Bhuyan said they reveal how far society remains from the benchmark of constitutional morality even 75 years into the Republic. He observed that while the Constitution lays down standards of equality and dignity, the morality practised within homes and communities often diverges sharply from those values.
He emphasised that constitutional morality requires governance through the rule of law rather than the rule of popular opinion. Referring to the evolution of the doctrine through judicial decisions, he cited Naz Foundation v Union of India, in which the Delhi High Court read down Section 377 of the Indian Penal Code, holding that popular morality cannot restrict fundamental rights under Article 21. Though the judgment was later overturned in Suresh Kumar Koushal v Naz Foundation, the Supreme Court ultimately restored and expanded the principle in Navtej Singh Johar v Union of India, affirming that constitutional morality must prevail over majoritarian views.
“In our constitutional scheme, it is the constitutionality of the issue before the court that is relevant, not the dominant or popular view,” he said.
Justice Bhuyan also addressed the functioning of the district judiciary, underlining that trial courts are the first point of contact for most litigants and form the foundation of the justice delivery system. He stressed that due importance must be given to the recording of evidence and adjudication of bail matters.
Highlighting the role of High Courts, he said their supervisory jurisdiction under Article 227 of the Constitution is intended as a shield to correct grave jurisdictional errors, not as a mechanism to substitute the discretion or factual appreciation of trial judges.
He recalled that several distinguished judges, including Justice H R Khanna, Justice A M Ahmadi, and Justice Fathima Beevi, began their careers in the district judiciary.
On representation within the judicial system, Justice Bhuyan noted that Telangana has made significant strides in gender inclusion. Out of a sanctioned strength of 655 judicial officers in the Telangana Judicial Service, 478 are currently serving, of whom 283 are women, exceeding 50 per cent representation. He added that members of Scheduled Castes, Scheduled Tribes, minority communities, and persons with disabilities are also represented in the state’s judiciary.
He observed that greater representation of women, marginalised communities, persons with disabilities, and sexual minorities would help make the judiciary more inclusive and reflective of India’s diversity. “The judiciary must represent all the colours of the rainbow and become a rainbow institution,” he said.
Justice Bhuyan also referred to the recent restoration by the Supreme Court of the requirement of a minimum three years of practice at the Bar for entry-level judicial posts. While acknowledging that the requirement ensures practical exposure, he cautioned that its impact on women aspirants, especially those from rural or small-town backgrounds facing social and financial constraints, would need to be carefully observed over time.
Concluding his address, he reiterated that the justice system must strive to bridge the gap between constitutional ideals and lived realities, ensuring that the rule of law remains paramount.
