GSLV-F18 success brings relief, but ISRO faces resource crunch

The successful GSLV-F18 launch of NVS-03 on 30 October 2026 comes as relief for ISRO after two PSLV failures in May 2025 and January 2026. A Hindu editorial warns that staff shortages, tight funding, slow procurement and technical setbacks threaten India's space ambitions. It calls for predictable funding, more scientists, domestic manufacturing and a national space law.

  3. Note3 / 7

    TECHNICAL AND OPERATIONAL CHALLENGES

    • Launch reliability: PSLV-C61 (2025) and PSLV-C62 (2026) both had problems in the third stage.
    • Satellite failure: NVS-02 (2025) did not reach its intended orbit because of an oxidiser-valve malfunction.
    • Complex missions: Gaganyaan, India's human spaceflight programme, and the Bharatiya Antariksh Station need advanced testing and human-rated systems.
    • Import dependence: Specialised electronic components are imported, exposing projects to supply disruptions.
    • Continuity: NavIC needs regular satellite replacement to keep services running.

    KEY CONCEPTS

    1. What is the difference between PSLV and GSLV?

    PSLV is ISRO's workhorse for low and sun-synchronous orbits. GSLV, with a cryogenic upper stage, carries heavier satellites to geosynchronous transfer orbit.

    1. What is IN-SPACe?

    The Indian National Space Promotion and Authorisation Centre authorises and supports private space activities, set up in 2020.

    1. What is NSIL?

    NewSpace India Limited is a public sector company under the Department of Space that commercialises ISRO's technology and launch services.

    1. What is the Indian Space Policy, 2023?

    It defines roles for ISRO, IN-SPACe, NSIL and private firms. It is a policy, not a law.

  7. Note7 / 7

    WAY FORWARD

    These are the editorial's suggestions, not adopted policy.

    • Fund predictably: Raise allocations for satellite replacement, launch vehicles and research.
    • Make components at home: Modernise the Semiconductor Laboratory, Mohali, and use the Electronics Component Manufacturing Scheme.
    • Strengthen people: Fill vacancies, expand specialised training and retain senior scientists.
    • Restructure: Empower NSIL and IN-SPACe to expand commercial and private activity.
    • Create a NavIC operator: Separate routine navigation services from ISRO's research role.
    • Pass a space law covering authorisation, liability, insurance and private participation.

    With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements: 1. IRNSS has three satellites in geostationary and four satellites in geosynchronous orbits. 2. IRNSS covers entire India and about 5500 sq. km beyond its borders. 3. India will have its own satellite navigation system with full global coverage by the middle of 2019. Which of the statements given above is/are correct?

    1. 1 only
    2. 1 and 2 only
    3. 2 and 3 only
    4. None
    Show answer

    Answer: A. Only statement 1 is correct, so the answer is (a) 1 only. Statement 1 is CORRECT. The IRNSS space segment is a constellation of seven satellites, called NavIC. Three sit in geostationary orbital slots and the remaining four in geosynchronous orbits with the required inclination and equatorial crossings in two different planes. Statement 2 is INCORRECT. IRNSS is designed to serve users in India and the region extending up to 1500 km from its boundary, which is its primary service area, with an extended service area beyond that. The figure of 5500 square kilometres both misstates the distance and uses the wrong unit for it. Statement 3 is INCORRECT. IRNSS is a regional system, and India will not have a satellite navigation system with full global coverage by the middle of 2019. SOURCE: ISRO IRNSS programme page, and The Hindu report on IRNSS-1I completing the navigation fleet. HOW TO CRACK IT: Read the unit, not just the number. Statement 2 offers an area in square kilometres where coverage beyond a border must be a distance, and 5500 square kilometres would be a trivially small patch. Unit mismatch is a quiet but reliable tell. The name itself, Indian Regional Navigation Satellite System, disposes of statement 3.

    Consider the following statements with regard to involvement of private entities in India's space programme: 1. Indian National Space Promotion and Authorisation Centre (IN-SPACe) is an autonomous agency formed to facilitate participation of private entities. 2. Agnikul Cosmos launched the world's first flight using 3D-printed rocket engine. 3. Skyroot Aerospace has developed liquid fuel for GSLV. Which of the statements given above is/are correct?

    1. 1 only
    2. 2 and 3 only
    3. 1 and 2 only
    4. 1, 2 and 3
    Show answer

    Answer: C. IN-SPACe (Indian National Space Promotion and Authorisation Centre) was established in 2020 as an autonomous body under the Department of Space to promote, support, and authorize private sector participation in India's space ecosystem. Statement 1 is correct: The Indian National Space Promotion and Authorisation Centre (IN-SPACe) is an autonomous agency formed to facilitate participation of private entities. It was established in 2020 as a single-window autonomous agency to encourage, support, and authorize private sector participation in India's space activities. Statement 2 is correct: Agnikul Cosmos launched the world's first flight using a 3D-printed rocket engine. Agnikul Cosmos achieved this milestone through its Agnibaan SOrTeD mission, which used a single-piece 3D-printed semi-cryogenic engine. Statement 3 is incorrect: Skyroot Aerospace developed the Vikram-S suborbital rocket using solid propulsion technology. It has not developed liquid fuel systems for GSLV, whose cryogenic engines were developed by ISRO. Statements 1 and 2 are correct, so the answer is Option (c).

    With reference to India's satellite launch vehicles, consider the following statements: 1. PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites. 2. Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth. 3. GSLV Mk III is a four-staged launch vehicle with the first and third stages using solid rocket motors, and the second and fourth stages using liquid rocket engines. Which of the statements given above is/are correct?

    1. 1 only
    2. 2 and 3
    3. 1 and 2
    4. 3 only
    Show answer

    Answer: A. Only statement 1 is correct, so the answer is (a) 1 only. Statement 1 is CORRECT. The PSLV is designed mainly to deliver earth observation or remote sensing satellites of up to about 1750 kg to sun-synchronous circular polar orbits at 600 to 900 km altitude, while the GSLV is designed mainly to deliver communication satellites to the highly elliptical Geosynchronous Transfer Orbit. Statement 2 is INCORRECT. Appearing permanently fixed in the sky describes a geostationary satellite. PSLV payloads go chiefly to polar sun-synchronous and lower earth orbits, so they do not appear fixed. Statement 3 is INCORRECT. GSLV Mk III is a three-stage heavy lift vehicle with two solid strap-ons, a core liquid booster and a cryogenic upper stage, not a four-staged vehicle in the configuration described. SOURCE: The Hindu explainer on the difference between GSLV and PSLV; ISRO launch vehicle pages. HOW TO CRACK IT: The reasoning chain runs from orbit to function. A satellite appears fixed only if it orbits at the same rate the Earth rotates, which requires geosynchronous altitude, and that is the GSLV's job. Fixing the vehicle to the orbit, and the orbit to the mission, resolves statements 1 and 2 together and leaves only the stage count to check.
