Current Affairs
Science & Technology
Science and technology current affairs is examined in a specific and fairly predictable way. Questions are rarely about the science itself; they are about the mission name, the launching organisation, the objective, the orbit or the destination — the identifying facts around a development rather than its technical content.
That is good news for candidates without a science background. Understanding the physics of a launch vehicle is not required; knowing which organisation launched it, what it carried and where it was going generally is.

Science and technology — September 2026
Science and technology current affairs this month: ISRO and fusion
Two items, both of the kind a science question is built from — a launch vehicle, a satellite, an orbit, a first; a device, a frequency, a facility, an international project.
| Date | What happened | Why it is asked |
|---|---|---|
| 17–19 September | SEMICON India 2026 opened at Yashobhoomi on the theme “Silicon to Systems”. The Prime Minister inaugurated the fifth SEMICON India on 17 September 2026 at Yashobhoomi, Dwarka, New Delhi, organised by the India Semiconductor Mission, MeitY and SEMI on the theme “Silicon to Systems: Building the Ecosystem” and running to 19 September: more than 600 companies from 52 countries, six country pavilions (Japan, South Korea, Malaysia, the Netherlands, Singapore and Sweden), twelve state pavilions and a “Sand to Silicon to Systems” value-chain walk-through. Twelve projects stand approved under the Semicon India programme and three of the first-phase units have begun commercial production. | Edition, venue, theme, organisers and the six pavilion countries are asked; so is the count of approved projects. (Prime Minister’s Office note of 16 September 2026; inauguration confirmed by agreeing reports of 17 September.) |
| 10 September | A 400-kW gyrotron was commissioned on the SST-1 tokamak. The Institute for Plasma Research, Gandhinagar, commissioned an 82.6 GHz, 400 kW gyrotron and integrated it with SST-1, the Steady State Superconducting Tokamak, on 10 September 2026. The gyrotron is a high-power microwave source for electron cyclotron resonance heating of the plasma, an upgrade on the earlier 42 GHz system, and supports India’s work under the international ITER project. | The institute, the tokamak’s name, the frequency and the ITER connection are what a science question uses. (Institute for Plasma Research, 10 September 2026.) |
| 4 September | GSLV-F17 launched EOS-05, India’s first geosynchronous imaging satellite. In the early hours of 4 September 2026 GSLV-F17, the 19th GSLV flight, lifted the 2,367-kg EOS-05 (GISAT-1A) from the second launch pad at Sriharikota into a transfer orbit from which the satellite raises itself to geosynchronous orbit at about 36,000 km. EOS-05 is India’s first imaging satellite designed to work from geosynchronous orbit, for near-real-time imagery in disaster, cyclone, agriculture and weather monitoring, and it was ISRO’s first successful launch of 2026 after the PSLV-C62 failure of 12 January. | Vehicle, satellite name, orbit type and the “first” are the facts; the 2021 loss of EOS-03 on GSLV-F10 is the natural comparison question. (ISRO, 4 September 2026.) |

Show answerHide answer
B. Institute for Plasma Research, Gandhinagar — The Institute for Plasma Research in Gandhinagar, on its SST-1 (Steady State Superconducting Tokamak), India’s fusion research device linked to ITER.
Q3EOS-05 (GISAT-1A), launched by GSLV-F17 in September 2026, is notable as India’s first
- ARadar imaging satellite

Show answerHide answer
B. Imaging satellite operating from geosynchronous orbit — The first Indian earth-imaging satellite designed to operate from geosynchronous orbit, giving near-real-time imagery; the earlier attempt, EOS-03 on GSLV-F10 in 2021, was lost.

What gets asked
The recurring categories
- Space missions — the mission name, the launch vehicle, the organisation, the objective and the destination or orbit. The most heavily examined science category by some margin.
- Defence technology — missile and aircraft names, their range or role, the developing organisation and induction status.
- Health and biotechnology — vaccines, disease outbreaks, medical approvals and the institutions involved.
- Emerging technology — artificial intelligence, quantum computing, semiconductors and the policy around them, generally at a conceptual level.
- Awards and recognitions in science — the prize, the field and the recipient.
Method
How to study it without a science background
Record the identifying facts rather than the mechanism. For a space mission: the name, the vehicle, the organisation, the objective, the destination. For a defence system: the name, the role, the range if stated, the developing organisation. That is what the questions ask, and it is entirely accessible to a candidate from any background. Where an examination does want conceptual understanding — UPSC in particular — a general grasp of what a technology does and why it matters is sufficient without technical depth.

Questions
Science & Technology — FAQs
Do I need a science background for science current affairs?
No. Questions are rarely about the science itself — they ask for the mission name, the launching organisation, the objective, the destination, the range of a system or the recipient of a prize. Those are identifying facts, accessible to a candidate from any background. Where an examination wants conceptual understanding, as UPSC sometimes does, a general grasp of what a technology does and why it matters is sufficient without technical depth.
Which science topics are examined most?
Space missions by a clear margin — the mission name, the launch vehicle, the organisation, the objective and the destination or orbit. After those, defence technology with system names, roles and developing organisations; health and biotechnology developments including vaccines and approvals; emerging technology such as artificial intelligence, quantum computing and semiconductors, generally at a conceptual level; and scientific awards with the field and recipient.
How should I record science current affairs?
As identifying facts on a themed page rather than as explanations. For a space mission: name, vehicle, organisation, objective, destination. For a defence system: name, role, range where stated, developing organisation. One line each. That is exactly what the questions ask for, it keeps the page short enough to revise weekly, and it avoids the trap of writing explanations you will never re-read.
