Science and Technology: India's Achievements
Science and Technology: India's Achievements
This topic closes the science block and usually contributes 1 question, most often on a space mission. It is the only part of the science section that changes with time, so learn the fixed milestones thoroughly and add recent launches in a short, dated list rather than rewriting your notes each month.
ISRO's Landmark Missions
| Mission | Launched | Outcome |
|---|---|---|
| Chandrayaan-1 | 22 October 2008 | Confirmed water molecules on the Moon |
| Mars Orbiter Mission (Mangalyaan) | 5 November 2013 | Entered Mars orbit on 24 September 2014 |
| Chandrayaan-2 | 22 July 2019 | Lander lost; orbiter still working |
| Chandrayaan-3 | 14 July 2023 | Soft landing on 23 August 2023 near the lunar south pole |
| Aditya-L1 | 2 September 2023 | Reached the L1 point in January 2024 to study the Sun |
| NISAR | 30 July 2025 | Dual-frequency Earth observation satellite |
India's Mars Orbiter Mission is remembered for succeeding at the first attempt. Chandrayaan-3 is remembered for the south-pole landing, an area no country had soft-landed in before.
Two Names That Came Out of Chandrayaan-3
- The landing site was named Shiv Shakti point.
- 23 August is now observed as National Space Day, marking the date of the landing.
Both were announced after the mission and both are standard one-line questions now. Gaganyaan is India's human spaceflight programme, running uncrewed test flights before a crewed mission; check the latest status close to your exam rather than trusting an older book.

Institutions Worth Knowing
| Body | Full form | Note |

| ISRO | Indian Space Research Organisation | Headquarters at Bengaluru |
| SDSC SHAR | Satish Dhawan Space Centre | Launch centre at Sriharikota |

| CSIR | Council of Scientific and Industrial Research | Research laboratories |
| BARC | Bhabha Atomic Research Centre | Nuclear research, Mumbai |
How to Prepare This Topic
- Fix the six milestone missions above — they will not change.
- Keep one page for launches in the twelve months before your exam.
- Learn dates as day and month only where a day has been named, such as 23 August.
- Do not memorise satellite technical specifications; papers ask purpose and year.
चंद्रयान 3 — 23 अगस्त 2023, चंद्रमा के दक्षिणी ध्रुव के पास, लैंडिंग स्थल का नाम शिव शक्ति पॉइंट।
TRE pointer: The north-pole-versus-south-pole swap is the single most common error on Chandrayaan-3, and the second is confusing the launch date of 14 July with the landing date of 23 August. National Space Day is a newer fact that older coaching material still misses entirely, which makes it a genuine advantage. With five options, −1/3 for a wrong answer and a compulsory option E for skipping, a mission you cannot date confidently is safer left unattempted than guessed.
60-Second Recap
- Chandrayaan-1 in 2008 confirmed water molecules on the Moon.
- Mangalyaan launched 5 November 2013, reached Mars orbit 24 September 2014, at the first attempt.
- Chandrayaan-3 launched 14 July 2023 and landed 23 August 2023 near the lunar south pole.
- The landing site is Shiv Shakti point; 23 August is National Space Day.
- Aditya-L1 launched September 2023 and reached L1 in January 2024 to study the Sun.
- ISRO headquarters at Bengaluru; launches from Satish Dhawan Space Centre, Sriharikota.
Frequently Asked Questions
When did Chandrayaan-3 land and where?
It landed on 23 August 2023 near the south pole of the Moon, after launching on 14 July 2023. No country had achieved a soft landing in that region before. The launch and landing dates are frequently offered as alternatives in the same question, so keep both fixed.
Why is 23 August observed as National Space Day?
Because it marks the day Chandrayaan-3 made its soft landing on the Moon in 2023. The landing site was named Shiv Shakti point at the same time. Both facts date from after the mission, so older study material usually omits them entirely.
What was special about India's Mars Orbiter Mission?
India reached Mars orbit at its very first attempt, which no other country had managed. The mission launched on 5 November 2013 and entered Mars orbit on 24 September 2014, operating far beyond its planned life while studying the Martian atmosphere and surface.
How much science and technology should I prepare for BPSC TRE?
Keep it proportionate. The topic usually yields one question in Part-II, so the six landmark missions, the two Chandrayaan-3 names, and the main research institutions are enough. Depth in the deficiency-disease and acid tables earns more marks than depth in satellite specifications.
Next step: Science rewards recall, and recall is built by testing rather than rereading. Take this chapter's questions in the BPSC TRE 4.0 mock test on ExamAtlas — same five-option pattern, same −1/3 negative marking, so you find out which tables you actually know.
